To evaluate whether a liposomal bupivacaine incisional block decreases postoperative pain and represents an opioid-minimizing strategy after scheduled cesarean delivery. In a single-blind, randomized controlled trial among opioid-naive women undergoing cesarean delivery, liposomal bupivacaine or placebo was infiltrated into the fascia and skin at the surgical site, before fascial closure. Using an 11-point numeric rating scale, the primary outcome was pain score with movement at 48 hours postoperatively. A sample size of 40 women per group was needed to detect a 1.5-point reduction in pain score in the intervention group. Pain scores and opioid consumption, in oral morphine milligram equivalents, at 48 hours postoperatively were summarized as medians (interquartile range) and compared using the Wilcoxon rank-sum test. Between March and September 2017, 249 women were screened, 103 women enrolled, and 80 women were randomized. One woman in the liposomal bupivacaine group was excluded after randomization as a result of a vertical skin incision, leaving 39 patients in the liposomal bupivacaine group and 40 in the placebo group. Baseline characteristics between groups were similar. The median (interquartile range) pain score with movement at 48 hours postoperatively was 4 (2-5) in the liposomal bupivacaine group and 3.5 (2-5.5) in the placebo group (P=.72). The median (interquartile range) opioid use was 37.5 (7.5-60) morphine milligram equivalents in the liposomal bupivacaine group and 37.5 (15-75) morphine milligram equivalents in the placebo group during the first 48 hours postoperatively (P=.44). Compared with placebo, a liposomal bupivacaine incisional block at the time of cesarean delivery resulted in similar postoperative pain scores in the first 48 hours postoperatively.

INTRODUCTION: Many patients suffer from mild, moderate or severe pain during or after root canal therapy. Theoretically, post-operative pain control can be achieved by using long-acting local anesthetics. The aim of this study was to evaluate the efficacy of a long acting anesthesia, bupivacaine, on preventing post-operative pain associated with endodontic treatment, and to compare it with lidocaine. MATERIALS AND METHODS: This study was a double blind and randomized clinical trial on 30 patients' anterior maxillary teeth. The patients were divided into two groups of fifteen. One group was administered lidocanine (2% with 1:100000 epinephrine) local anesthesia and the other group was given bupivacaine (0.5% without epinephrine). The pain in patients were compared using the visual analogue scale (VAS) at definite times i.e. before treatment, during treatment and 2,4,6,8,10,12,24,36 and 48 hours after operation. Data were analyzed using One-way ANOVA tests. RESULTS: Bupivacaine significantly decreased postoperative pain compared to lidocaine. Postoperative pain was directly related to preoperative pain. Women reported more pain, though significant difference in postoperative pain report was not found between different ages. CONCLUSION: In conclusion, a single dose of bupivacaine 0.5% used in infiltration anesthesia could be more effective in reduction or prevention of post-operative endodontic pain compared with lidocaine.

First trimester abortions especially cervical dilation and suction aspiration are associated with pain, despite various methods of pain control. Compare different methods of pain control during first trimester surgical abortion. We searched multiple electronic databases with the appropriate key words, as well as reference lists of articles, and contacted professionals to seek other trials. Randomized controlled trials comparing methods of pain control in first trimester surgical abortion at less than 14 weeks gestational age using electric or manual suction aspiration. Outcomes included intra- and postoperative pain, side effects, recovery measures and satisfaction. Two reviewers independently extracted data. Meta-analysis results are expressed as weighted mean difference (WMD) or Peto Odds ratio with 95% confidence interval (CI). We included forty studies with 5131 participants. Due to heterogeneity we divided studies into 7 groups:Local anesthesia: Data was insufficient to show a clear benefit of a paracervical block (PCB) compared to no PCB or a PCB with bacteriostatic saline. Pain scores during dilation and aspiration were improved with deep injection (WMD -1.64 95% CI -3.21 to -0.08; WMD 1.00 95% CI 1.09 to 0.91), and with adding a 4% intrauterine lidocaine infusion (WMD -2.0 95% CI -3.29 to -0.71, WMD -2.8 95% CI -3.95 to -1.65 with dilation and aspiration respectively).PCB with premedication: Ibuprofen and naproxen resulted in small reduction of intra- and post-operative pain.Analgesia: Diclofenac-sodium did not reduce pain.Conscious sedation: The addition of conscious intravenous sedation using diazepam and fentanyl to PCB decreased procedural pain.General anesthesia (GA): Conscious sedation increased intraoperative but decreased postoperative pain compared to GA (Peto OR 14.77 95% CI 4.91 to 44.38, and Peto OR 7.47 95% CI 2.2 to 25.36 for dilation and aspiration respectively, and WMD 1.00 95% CI 1.77 to 0.23 postoperatively). Inhalation anesthetics are associated with increased blood loss (p<0.001).GA with premedication: The COX 2 inhibitor etoricoxib, the non-selective COX inhibitors lornoxicam, diclofenac and ketorolac IM, and the opioid nalbuphine were improved postoperative pain.Non-pharmacological intervention: Listening to music decreased procedural pain.No major complication was observed. Conscious sedation, GA and some non-pharmacological interventions decreased procedural and postoperative pain, while being safe and satisfactory to patients. Data on the widely used PCB is inadequate to support its use, and it needs to be further studied to determine any benefit.

Objectives. The objective of this narrative review was to examine the usage of ketamine as a postoperative analgesic agent across a wide variety of surgeries. Design. A literature search was performed using the phrases “ketamine” and “postoperative pain.” The authors analyzed the studies that involved testing ketamine's effectiveness at controlling postoperative pain. Effectiveness was assessed through various outcomes such as the amount of opiate consumption, visual analog scale (VAS) pain scores, and persistent postoperative pain at long-term follow-up. Results. While many different administration protocols were evaluated, delivering ketamine both as a pre- or perioperative bolus and postoperative infusion for up to 48 hours appeared to be the most effective. These effects are dose-dependent. However, a number of studies analyzed showed no benefit in using ketamine versus placebo for controlling postoperative pain. While ketamine is a safe and well-tolerated drug, it does have adverse effects, and there are concerns for possible neurotoxicity and effects on memory. Conclusions. In a number of limited situations, ketamine has shown some efficacy in controlling postoperative pain and decreasing opioid consumption. More randomized controlled trials are necessary to determine the surgical procedures and administrations (i.e., intravenous, epidural) that ketamine is best suited for. PMID:26495312

Topical metronidazole (10 percent) has been previously demonstrated to decrease postoperative pain after hemorrhoidectomy. The aim of this study was to evaluate the effect of topical metronidazole (10 percent) in reducing postoperative and after-defecation pain of hemorrhoidectomy. A double-blind, randomized trial was conducted to compare posthemorrhoidectomy pain with use of topical metronidazole (10 percent) vs. placebo carrier, applied to surgical site. Forty-seven patients were randomly allocated to receive metronidazole (n=25) or placebo (n=22). Pain was assessed using a visual analog scale preoperatively and on postoperative hours 6 and 12 and at days 1, 2, 7, and 14. The use of narcotic, additional analgesics, and complications were recorded. (Pain scores were calculated and compared with baseline values and control group (t test, SPSS ver.10). Patients in the topical metronidazole group had significantly less postoperative pain than those in the placebo group up to day 14 (P

OBJECTIVES Video-assisted thoracoscopic surgery (VATS) and median sternotomy (MS) are two approaches in lung-volume reduction surgery (LVRS). This study focused on the two surgical approaches with regard to postoperative pain. METHODS In this prospective, non-randomized study, pain was measured preoperatively and postoperatively using the visual analog scale (VAS) and the brief pain inventory (BPI). Incentive spirometry (IS) assessed restriction of the thoracic cage due to pain. Factors associated with treatment complications, medication usage, hospital stay, operating times, and chest-tube duration differences were examined between groups. RESULTS Of 85 patients undergoing LVRS, 23 patients underwent reduction via MS and 62 patients via bilateral VATS. VAS scores revealed no difference in postoperative pain except for VAS scores on days 6 (PM) and 7 (PM). BPI scores yielded higher scores in the VATS group on postoperative day (POD) 1 in the reactive dimension, but no other overall differences. MS patients receiving tramadol consumed a higher mean amount than VATS patients on POD 5 and POD 6. IS change from baseline to postoperative were similar between groups, and increased pain correlated with decreased IS scores on POD 1. Chest-tube duration, complications, and pain medication were similar between groups. CONCLUSIONS Bilateral VATS and MS offer similar outcomes with regard to postoperative pain and complications. These results suggest that the choice of LVRS operative approach should be dependent on disease presentation, surgeon expertise, and patient preference, not based upon differences in perceived postoperative pain between MS and bilateral VATS.

Local external cooling of the surgical field after joint surgery is intended to enhance recovery and to facilitate the use of outpatient surgery by reducing pain and improving mobility. We hypothesized that the effects of postoperative cooling and compression after knee arthroscopy would be reflected in changes in the concentrations of metabolic and inflammatory markers in the synovial membrane. Forty otherwise healthy patients who were to undergo knee arthroscopy were included in the study, and half were randomized to receive postoperative cooling and compression. Microdialysis of the synovial membrane was performed postoperatively, and the concentrations of prostaglandin E₂ (PGE₂), glucose, lactate, glycerol, and glutamate as well as the ethanol exchange ratio (which indicates blood flow) were measured. The temperature of the knee was monitored, and postoperative pain was assessed by the patient with use of a visual analog scale, a numeric rating scale, and the need for rescue medication. Application of the cooling and compression device after knee arthroscopy significantly lowered the temperature in the operatively treated knee (as measured on the skin, within the joint capsule, and intra-articularly). The cooling and compression appeared to decrease inflammation, as indicated by a temperature-sensitive decrease in the PGE₂ concentration. The hypothermia also decreased the metabolic rate of the synovial tissue and thus decreased energy requirements, as shown by the stability of the lactate concentration over time despite the decreased blood flow that was indicated by the increasing ethanol exchange ratio. No effect of the compression and cooling on postoperative pain was detected. Local cryotherapy and compression after knee arthroscopy significantly lowered the temperature in the knee postoperatively, and the synovial PGE₂ concentration was correlated with the temperature. Since PGE₂ is a marker of pain and inflammation, the postoperative local cooling and compression appeared to have a positive anti-inflammatory effect.

To compare clinical efficacy and complication rate as measured by postoperative falls and development of peripheral neuritis between intra-articular blockade and femoral nerve block in patients undergoing arthroscopic hip surgery. An institutional review board approved retrospective review was conducted on a consecutive series of patients who underwent elective arthroscopic hip surgery by a single surgeon, between November 2013 and April 2015. Subjects were stratified into 2 groups: patients who received a preoperative femoral nerve block for perioperative pain control, and patients who received an intra-articular "cocktail" injection postoperatively. Demographic data, perioperative pain scores, narcotic consumption, incidence of falls, and iatrogenic peripheral neuritis were collected for analysis. Postoperative data were then collected at routine clinical visits. A total of 193 patients were included in this study (65 males, 125 females). Of them, 105 patients received preoperative femoral nerve blocks and 88 patients received an intraoperative intra-articular "cocktail." There were no significant differences in patient demographics, history of chronic pain (P = .35), worker's compensation (P = .24), preoperative pain scores (P = .69), or intraoperative doses of narcotics (P = .40). Patients who received preoperative femoral nerve blocks reported decreased pain during their time in PACU (P = .0001) and on hospital discharge (P = .28); however, there were no statistically significant differences in patient-reported pain scores at postoperative weeks 1 (P = .34), 3 (P = .64), and 6 (P = .70). Administration of an intra-articular block was associated with a significant reduction in the rate of postoperative falls (P = .009) and iatrogenic peripheral neuritis (P = .0001). Preoperative femoral nerve blocks are associated with decreased immediate postoperative pain, whereas intraoperative intra-articular anesthetic injections provide effective postoperative pain control in patients undergoing arthroscopic hip surgery and result in a significant reduction in the rate of postoperative falls and iatrogenic peripheral neuritis.

Assessment of postoperative pain is a fundamental aspect of post-surgical care. When surgery is performed as an outpatient, the parents are mainly responsible for the assessment of pain, but they may not always correctly evaluate their children's pain. This makes it necessary to have tools that help them to assess postoperative pain reliably. The Parent's Postoperative Pain Measurement (PPPM) is a behavioral measurement tool of post-operative pain developed to help parents to assess their children's post-operative pain. The purpose of this work was to translate this scale into Spanish, and validate the psychometric properties of the Spanish version of the scale. Participants were 111 children aged 2 to 12 years, who had undergone surgery, and one of their parents. After the operation, the children's level of pain was assessed, and the parents completed the PPPM scale in Spanish. The PPPM items in Spanish showed good internal consistency (Cronbach alpha between 0.784 and 0.900) and the scale scores were closely related to the global pain assessment (Spearman's rho correlation between 0.626 and 0.431). The score on the scale decreased between the day of the operation and the next day, and discriminated well between children undergoing surgery qualified as low/moderate pain and high pain. We conclude that the Spanish version of the PPPM scale evaluated in this study, has good psychometric properties to assess postoperative pain by parents at home.

Effective pain management is an essential component in the perioperative care of surgical patients. However, postoperative pain after maxillofacial fracture repair and its optimal therapy has not been described in detail. In a prospective cohort study, 95 adults rated their pain on the first postoperative day after maxillofacial fracture repair using the questionnaire of the Quality Improvement in Postoperative Pain Management (QUIPS) project. Quality Improvement in Postoperative Pain Management allowed for a standardized assessment of patients' characteristics and pain-related parameters. Overall, the mean maximal pain and pain on activity (numeric rating scales) were significantly higher in patients with mandibular fractures than in patients with midface fractures (P = 0.002 and P = 0.045, respectively). In patients with mandibular fractures, a longer duration of surgery was significantly associated with higher satisfaction with pain intensity (P = 0.015), but was more frequently associated with postoperative vomiting (P = 0.023). A shorter duration of surgery and an absence of preoperative pain counseling in these patients were significantly correlated to desire for more pain medication (P = 0.049 and P = 0.004, respectively). Patients with mandibular fractures that received opioids in the recovery room had significantly higher strain-related pain (P = 0.017). In patients with midface fractures, a longer duration of surgery showed significantly higher levels of decreased mobility (P = 0.003). Patients receiving midazolam for premedication had significantly less minimal pain (P = 0.021). Patients with mandibular fractures seem to have more postoperative pain than patients with midface fractures. Monitoring of postsurgical pain and a procedure-specific pain-treatment protocol should be performed in clinical routine.

The prevalence of unrelieved postoperative pain is high and may lead to adverse effects including prolonged hospitalization and delayed recovery. Distraction may be an effective pain-relieving strategy, and can be implemented by several means including affective imaging, games, and possibly music. The aim of this study was to explore the effect of music therapy on postoperative pain. Fifty-seven patients (24 females, 33 males; mean +/- SD age 39.9 +/- 14.35 years [range 15 to 69 years] were matched for age and sex and then nonselectively assigned to either an experimental (n = 27) or a control (n = 30) group. Music was played intermittently to members of the experimental group during the first 24 hour postoperative period. Pain intensity was measured using the Pain Verbal Rating Scales (VRS). Significant decreases in pain intensity over time were found in the experimental group compared to the control group (p < 0.0001). In addition, the experimental group had a lower systolic blood pressure and heart rate, and took fewer oral analgesics for pain. These findings suggest that music therapy is an effective nonpharmacologic approach for postoperative pain management.

In recent years, gabapentin has gained popularity as an adjuvant therapy for the treatment of postoperative pain. Numerous studies have shown a decrease in pain score, even with immediate postoperative activity, which is significant for early post-op ambulation and regaining functionality sooner. However, studies have been in conclusive in patients undergoing lower extremity orthopedic surgery. For this reason, we hoped to study the effect of gabapentin on postoperative pain in patients undergoing total knee arthroplasty, total hip arthroplasty, or a hip fracture repair. This was done in the setting of ensuring adequate postoperative analgesia with regional blocks and opioid PCA, as is protocol at our institution. Given the sedative effects of gabapentin and the potential for improving postoperative sleep patterns, we also studied the drug's effect on this aspect of our patient's postoperative course. We utilized the Pittsburg Sleep Quality Index and Visual Analog Scale for pain to obtain a more objective standardized score amongst our study population. Our results indicate that gabapentin does not offer any additional relief in pain or improve sleep habits in patients who have received either a femoral or lumbar plexus block for lower extremity orthopedic surgery. This trial is registered with NCT01546857. PMID:28348503

Multimodal pain protocols have been proposed to achieve improved long-acting postoperative analgesia. Controlling postoperative pain after joint arthroplasty is especially important as it relates to patient satisfaction and outcomes. The purpose of this study was to compare the postoperative pain, time to ambulation, and overall narcotic usage between patients who received either a femoral nerve block with a periarticular bupivacaine injection or a periarticular bupivacaine and extended-release liposomal bupivacaine injection after primary total knee arthroplasty. A total of 597 consecutive primary total knee arthroplasties performed between September 1, 2012 and August 31, 2014 received preoperative celecoxib, oxycodone, and transdermal scopolamine. Intraoperatively, patients either received a single-dose bupivacaine femoral nerve block along with 30-mL 0.25% bupivacaine periarticular injection (group A) or a 60-mL periarticular injection alone (20-mL liposomal bupivacaine, 30-mL 0.25% bupivacaine, and 10-mL saline; group B). The postoperative pain scores, narcotic usage, and time to ambulation were retrospectively collected from the electronic medical record. These outcomes were compared between treatment groups. There were 325 patients in group A compared with 272 in group B during the time frame. There was no difference among age, gender, race, and body mass index between the groups. Group B demonstrated a decreased need for breakthrough pain medication (16.9% vs 36.3% P < .001), decreased pain 12 hours postoperatively (3.2 vs 3.6 P < .003), and an earlier time to ambulation (29.5 hours vs 32.2 hours, P < .017). There was no difference in hospital length of stay (2.8 vs 2.6 days, P = .123). On controlling for demographic factors, patients in group B were able to ambulate 2.3 hours earlier than those in group A (coefficient = -2.3, P = .049). Liposomal bupivacaine resulted in a decrease need for breakthrough pain medication, improved pain scores at 12 hours, and an earlier time to ambulation compared to a combined femoral nerve block and periarticular bupivacaine injection.

Recent meta-analyses have concluded that low-dose intravenous ketamine infusions (LDKIs) during the postoperative period may help to decrease acute and chronic postoperative pain after major surgery. This study aims to evaluate the level of pain at least 3 months after surgery for patients treated with a postoperative LDKI versus patients who were not treated with a postoperative LDKI. Administrative and Ethics Board approval were obtained for this study. We performed a retrospective chart review for all patients receiving LDKI, and equal number of age-, sex-, and surgery-matched patients who did not receive LDKI. Low-dose ketamine was prepared using 100 mg of ketamine in 100 ml of normal saline and run between 50 and 200 mcg/kg/h. We reviewed 115 patients with LDKI and 115 without LDKI. The average age was 63.1 years, 73% of the patients were men and sex was evenly distributed between LDKI and non-LDKI. The average duration of the ketamine infusions was 26.8 h with the average dose being 169.9 mg. At an average of 9 months after surgery, 42% of the ketamine group and 38% of the nonketamine group stated that they had had pain on discharge. Of these patients, 30% of the ketamine group and 26% of the nonketamine group still had pain at the time of the phone call. Women in both groups had more acute and chronic pain than men. These results show that LDKI does not promote a decrease in long-term postoperative pain.

The aim of this study was to describe stress symptoms among adolescents before and after scoliosis surgery and to explore correlations with postoperative pain. Scoliosis surgery is a major surgical procedure. Adolescent patients suffer from preoperative stress and severe postoperative pain. Previous studies indicate that there is a risk of traumatisation and psychological complications during the recovery period. A prospective quantitative cohort study with consecutive inclusion of participants. A cohort of 37 adolescent patients aged 13-18. To assess the adolescents' experiences before surgery and at six to eight months after surgery, the Trauma Symptom Checklist for Children - Alternative version, Youth Self-Report and Kiddie Schedule for Affective Disorder and Schizophrenia for children 12-18 were used. The Visual Analogue Scale was used for self-report of postoperative pain on day three. Rates of anxiety/depression and internalising behaviour were significantly higher before surgery than six months after. Preoperative anger, social problems and attention problems correlated significantly with postoperative pain on day three. At follow-up, postoperative pain correlated significantly with anxiety, social problems and attention problems. The results of this study indicate a need for interventions to reduce perioperative stress and postoperative pain to improve the quality of nursing care. Attention to preoperative stress and implementation of interventions to decrease stress symptoms could ameliorate the perioperative process by reducing levels of postoperative pain, anxiety, social and attention problems in the recovery period. © 2016 John Wiley & Sons Ltd.

Midurethral slings are commonly used to treat stress urinary incontinence. Pain control, however, may be a concern. Liposomal bupivacaine is a local anesthetic with slow release over 72 hours, demonstrated to lower pain scores and decrease narcotic use postoperatively. The purpose of this study was to examine the impact of liposomal bupivacaine on pain scores and narcotic consumption following retropubic midurethral sling placement. This randomized, placebo-controlled trial enrolled women undergoing retropubic midurethral sling procedures with or without concomitant anterior or urethrocele repair. Subjects were allocated to receive liposomal bupivacaine (intervention) or normal saline placebo injected into the trocar paths and vaginal incision at the conclusion of the procedure. At the time of drug administration, surgeons became unblinded, but did not collect outcome data. Participants remained blinded to treatment. Surgical procedures and perioperative care were standardized. The primary outcome was the visual analog scale pain score 4 hours after discharge home. Secondary outcomes included narcotic consumption, time to first bowel movement, and pain scores collected in the mornings and evenings until postoperative day 6. The morning pain item assessed "current level of pain"; the evening items queried "current level of pain," "most intense pain today," "average pain today with activity," and "average pain today with rest." Likert scales were used to measure satisfaction with pain control at 1- and 2-week postoperative intervals. Sample size calculation deemed 52 subjects per arm necessary to detect a mean difference of 10 mm on a 100-mm visual analog scale. To account for 10% drop out, 114 participants were needed. One hundred fourteen women were enrolled. After 5 exclusions, 109 cases were analyzed: 54 women received intervention, and 55 women received placebo. Mean participant age was 52 years, and mean body mass index was 30.4 kg/m 2 . Surgical and demographic characteristics were similar, except for a slightly higher body mass index in the placebo group (31.6 vs 29.2 kg/m 2 ; P=.050), and fewer placebo arm subjects received midazolam during anesthesia induction (44 vs 52; P=.015). For the primary outcome, pain score (millimeter) 4 hours after discharge home was lower in the intervention group (3.5 vs 13.0 millimeters; P=.014). Pain scores were also lower for subjects receiving liposomal bupivacaine at other time points collected during the first three postoperative days. Furthermore, fewer subjects in the intervention group consumed narcotic medication on postoperative day 2 (12 vs 27; P=.006). There was no difference in satisfaction with pain control between groups. Side-effects experienced, rate of postoperative urinary retention, and time to first bowel movement were similar between groups. Finally, no serious adverse events were noted. Liposomal bupivacaine decreased postoperative pain scores following retropubic midurethral sling placement, though pain was low in both the intervention and placebo groups. Participants who received liposomal bupivacaine were less likely to use narcotics on postoperative day 2. For this common outpatient surgery, liposomal bupivacaine may be a beneficial addition. Given the cost of this intervention, however, future cost-effective analyses may be useful. Published by Elsevier Inc.

To determine whether massage therapy improves postoperative mood, pain, anxiety, and physiologic measurements; shortens hospital stay; and decreases occurrence of atrial fibrillation. Two hundred fifty-two adults undergoing cardiac surgery were randomized to usual postoperative care (n=126) or usual care plus two massages (n=126). Assessments of mood, depression, anxiety, pain, physiologic status, cardiac rhythm, and hospital length of stay were completed. Logistic and linear regressions were performed. Preoperative pain, mood, and affective state scores were positively associated with postoperative scores; however, there were no postoperative differences between groups for any measures (P=.11 to .93). There were no differences in physiologic variables except lower postoperative blood pressure after massage (P = .01). Postoperative atrial fibrillation occurrence (P = .6) and median postoperative hospital length of stay (P = .4) were similar between groups. Massage therapy is feasible in cardiac surgical patients; however, it does not yield therapeutic benefit. Nevertheless, it should be a patient-selected and -paid option.

OBJECTIVE: To compare two thoracotomy closure techniques (pericostal and transcostal suture) in terms of postoperative pain and pulmonary function. METHODS: This was a prospective, randomized, double-blind study carried out in the Department of Thoracic Surgery of the Luzia de Pinho Melo Hospital das Clínicas and at the University of Mogi das Cruzes, both located in the city of Mogi das Cruzes, Brazil. We included 30 patients (18-75 years of age) undergoing posterolateral or anterolateral thoracotomy. The patients were randomized into two groups by the type of thoracotomy closure: pericostal suture (PS; n = 16) and transcostal suture (TS; n = 14). Pain intensity during the immediate and late postoperative periods was assessed by a visual analogic scale and the McGill Pain Questionnaire. Spirometry variables (FEV1, FVC, FEV1/FVC ratio, and PEF) were determined in the preoperative period and on postoperative days 21 and 60. RESULTS: Pain intensity was significantly greater in the PS group than in the TS group. Between the preoperative and postoperative periods, there were decreases in the spirometry variables studied. Those decreases were significant in the PS group but not in the TS group. CONCLUSIONS: The patients in the TS group experienced less immediate and late post-thoracotomy pain than did those in the PS group, as well as showing smaller reductions in the spirometry parameters. Therefore, transcostal suture is recommended over pericostal suture as the thoracotomy closure technique of choice. PMID:25210961

Expansive open-door laminoplasty (EOLP) is a useful technique for multiple-level cervical spondylotic myelopathy. The common postoperative complications of EOLP include moderate to severe neck pain, loss of cervical lordosis, decrease of cervical range of motion, and C5 palsy. We modified the surgical technique to lessen these complications. This study is aimed to elucidate the efficacy of modified techniques to lessen the complications of traditional procedures. We collected data from 126 consecutive patients treated at our institution between August 2008 and December 2012. Of these, 66 patients underwent conventional EOLP (CEOLP) and the other 60 patients underwent modified EOLP (MEOLP). The demographic and preoperative data, axial pain visual analog scale scores at 2 weeks and 3 months postoperatively, clinical outcomes evaluated using Nurick score and Japanese Orthopedic Association recovery rate at 12 months postoperatively, and radiographic results assessed using plain films at 3 months and 12 months postoperatively for both groups were compared and analyzed. There were no significant differences regarding the preoperative condition between the CEOLP and MEOLP groups (p > 0.05). The Japanese Orthopedic Association recovery rate of the MEOLP group was 70.3%, comparable to the result of the other group (70.2%). Postoperative axial neck pain, loss of range of motion, and loss of lordosis of cervical curvature decreased significantly in the MEOLP group (p < 0.05). The complications of temporary C5 nerve palsy found in the CEOLP group did not exist in the MEOLP group. MEOLP is a minimally invasive surgical method to treat multiple-level cervical spondylotic myelopathy, which decreases postoperative complications effectively. Copyright © 2014.

Effective pain management after anterior cruciate ligament (ACL) reconstruction improves patient satisfaction and function. To collect and evaluate the available evidence from randomized controlled trials (RCTs) on pain control after ACL reconstruction. Systematic review. A systematic literature review was performed using PubMed, Medline, Google Scholar, UpToDate, Cochrane Reviews, CINAHL, and Scopus following PRISMA guidelines (July 2014). Only RCTs comparing a method of postoperative pain control to another method or placebo were included. A total of 77 RCTs met inclusion criteria: 14 on regional nerve blocks, 21 on intra-articular injections, 4 on intramuscular/intravenous injections, 12 on multimodal regimens, 6 on oral medications, 10 on cryotherapy/compression, 6 on mobilization, and 5 on intraoperative techniques. Single-injection femoral nerve blocks provided superior analgesia to placebo for up to 24 hours postoperatively; however, this also resulted in a quadriceps motor deficit. Indwelling femoral catheters utilized for 2 days postoperatively provided superior analgesia to a single-injection femoral nerve block. Local anesthetic injections at the surgical wound site or intra-articularly provided equivalent analgesia to regional nerve blocks. Continuous-infusion catheters of a local anesthetic provided adequate pain relief but have been shown to cause chondrolysis. Cryotherapy improved analgesia compared to no cryotherapy in 4 trials, while in 4 trials, ice water and water at room temperature provided equivalent analgesic effects. Early weightbearing decreased pain compared to delayed weightbearing. Oral gabapentin given preoperatively and oral zolpidem given for the first week postoperatively each decreased opioid consumption as compared to placebo. Ibuprofen reduced pain compared to acetaminophen. Oral ketorolac reduced pain compared to hydrocodone-acetaminophen. Regional nerve blocks and intra-articular injections are both effective forms of analgesia. Cryotherapy-compression appears to be beneficial, provided that intra-articular temperatures are sufficiently decreased. Early mobilization reduces pain symptoms. Gabapentin, zolpidem, ketorolac, and ibuprofen decrease opioid consumption. Despite the vast amount of high-quality evidence on this topic, further research is needed to determine the optimal multimodal approach that can maximize recovery while minimizing pain and opioid consumption. These results provide the best available evidence from RCTs on pain control regimens after ACL reconstruction. © 2015 The Author(s).

To assess the impact of a short hypnotic session on postoperative anxiety and pain in major orthopaedic surgery. Despite specific information given before a scheduled paediatric surgery, perioperative anxiety can become important. Randomised Clinical Study. The study is an open single-centre randomised clinical study comparing a "control" group versus a "hypnosis" group receiving a short hypnosis pre-induction session as additional experimental analgesic procedure. The primary endpoint was the postoperative anxiety, blindly assessed using a visual analogue scale. The study involved 120 children (age 10-18 years). The results showed no difference between control group versus hypnosis group. Twenty-four hours after surgery (Day+1), the patient's anxiety score was not different between control and hypnosis groups (median [Q1-Q3]: 1 [0; 3] vs. 0 [0; 3], respectively, p = .17). Each group experienced a significant decrease in anxiety level between the day before surgery (Day-1) and the day after surgery (Day+1) (median ([Q1-Q3]) difference of the anxiety score: 2 [4; 0] and 2 [4; 0], respectively, p < .0001 in each group). The postoperative pain scores were low and not different between groups (median [Q1-Q3]: 2 [0; 3] in control group vs. 3 [1; 3] in hypnosis group, p = .57). This randomised study on a short hypnosis session performed in the operating room prior to a major surgery showed no difference in postoperative anxiety and pain levels. The decrease in anxiety and pain levels may be due to the addition of nurse pre-operative interviews and optimisation in communication in the operating room. As postoperative anxiety level was low in both control and hypnosis groups, nurse pre-operative interviews and nurse training in hypnosis may contribute to the optimisation of global management and decrease the postoperative anxiety level. © 2017 John Wiley & Sons Ltd.

To examine whether the addition of intravenous dexamethasone during total knee arthroplasty (TKA) would be effective at reducing postoperative pain scores and postoperative opioid consumption. A total of 102 patients undergoing TKA were placed into two groups: 55 subjects received intraoperative dexamethasone 8 mg intravenously (treatment group) and 47 did not receive dexamethasone at any time during the perioperative period. Comparison was made using the 0-10 numeric pain rating scale and the amount of opioids used in each group. Patients who received dexamethasone required significantly less oral opioids compared to the control group. Pain scores at 24 h post-surgery were significantly less for the dexamethasone group compared to the control group. There was no difference between groups in regards to patient-controlled analgesic dose or pain scores in the post-anesthesia care unit, at 12 or 48 h post-surgery. A single dose of dexamethasone given intraoperatively significantly decreased oral narcotic consumption and decreased pain scores 24 h postoperatively. Dexamethasone appears to be a safe modality to use to control pain in patients undergoing TKA. © 2017 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

Nasal packing is usually performed to control bleeding after endoscopic sinus surgery (ESS). Although new packing materials have been developed, they still cause pain. This study was designed to evaluate the effect of lidocaine-soaked packs on pain after ESS. A prospective, randomized, double-blind controlled trial was conducted in 63 patients with CRS undergoing ESS. At the conclusion of the operation, 2% lidocaine-soaked biodegradable synthetic polyurethane foam and saline-soaked polyurethane foam were inserted in both nasal cavities of 31 patients and 32 control patients, respectively. The same lidocaine or saline was reapplied into the nasal packs at postoperative 8 hours. Pain was evaluated using a visual analog scale at postoperative 1, 4, 8, 16, 20, and 24 hour(s). The number of gauze that cleaned the blood around the nose was counted. Heart rate, rhythm, and blood pressures were checked preoperatively and postoperatively to evaluate the influence of lidocaine on vital signs. Postoperative pain decreased in lidocaine group at all of the postoperative time periods (p < 0.05). Lidocaine reduced postoperative bleeding at postoperative 8 and 24 hours. Changes of blood pressure from preoperative values in the lidocaine group were not different from those in the control group (p > 0.05). Heart rate in the lidocaine group was more stable than that in the control group (p < 0.05). Lidocaine-soaked packs significantly reduced postoperative pain without serious changes on vital sign. These findings suggest that topical lidocaine application to nasal packs could be a useful method to reduce pain during the early postoperative period after ESS.

To compare the incidence of postoperative pain after the use of calcium hydroxide powder mixed with normal saline or 0.2% chlorhexidine digluconate as intracanal medicament. Fifty-five subjects aged 17-60 years with teeth diagnosed to have apical periodontitis. Two-visit conventional root canal treatment of seventy teeth. The teeth were divided by randomization (balloting) into two groups: control group and experimental group, each with thirty-five teeth treated with calcium hydroxide mixed with normal saline or with 0.2% chlorhexidine digluconate as intracanal medicament respectively. Incidence of postoperative pain was assessed using the universal pain assessment tool and whether or not analgesic was taken. Incidence of post-operative pain. Postoperative pain occurred only at 1-day and 1-week reviews. In the control group, the overall incidence of pain was the same at both review periods (5.7%), while the experimental group showed a slight decrease in incidence between 1-day (17.2%) and 1-week (11.4%) reviews. Incidence of flare-ups was more in the experimental group (11.4%) than in the control group (5.7%). No significant statistical differences between the two groups were observed (p > 0.05). The incidence of postoperative pain was lower in the normal saline treatment group, but the difference was not statistically significant.

To determine whether preoperative epidural administration of morphine and detomidine would decrease postoperative lameness after bilateral stifle arthroscopy in horses. Prospective clinical controlled study. Eight adult horses that had bilateral arthroscopic procedures, including drilling of cartilage and subchondral bone within the femoropatellar joints. Horses were randomly separated into 2 groups. Preoperatively, 4 horses were administered a combination of epidural morphine (0.2 mg/kg) and detomidine (30 microg/kg), and 4 horses were administered an equivalent volume of epidural saline (0.9% NaCl) solution. Postoperative pain was assessed using 6 video recordings made at hourly intervals of each horse at a walk. Assessments began 1 hour after recovery from anesthesia. The recordings were scrambled out of sequence and evaluated by 3 observers, unaware of treatment groups, who scored lameness from 0 to 4. Lameness scores of the 2 groups of horses were compared using a Wilcoxon's rank sum test. Heart and respiratory rates were also measured at each hourly interval and compared between groups using a repeated-measures ANOVA; statistical significance was set at P <.05. Preoperative administration of epidural morphine and detomidine significantly decreased lameness and heart rates after bilateral stifle arthroscopy. The greatest decrease was detected at hours 1 and 2 after recovery from anesthesia. We conclude that horses undergoing a painful arthroscopic procedure of the stifle joint benefit from the administration of preoperative epidural morphine and detomidine. Preoperative epidural administration of detomidine and morphine may be useful in decreasing postoperative pain after stifle arthroscopy as well as pain associated with other painful disorders involving the stifle joint, such as septic arthritis and trauma.

2013-10-01

Ambulatory knee surgery is a common procedure with over 100,000 knee arthroscopies performed in the U.K. in 2010-2011. Pain after surgery can decrease patient satisfaction, delay discharge, and decrease cost effectiveness. Multi-modal therapies, including complementary therapies, to improve pain control after surgery have been recommended. However, a comprehensive review of the literature regarding the use of complementary therapies to enhance pain control after ambulatory knee surgery is lacking, and this article aims to address this deficit. CINHAL, EMBASE, MEDLINE, AMED and CENTRAL databases were searched. Only Randomised Controlled Trials were included. All eligible papers were quality assessed using the Jadad system, and data was extracted using piloted forms. Two independent reviewers performed each stage of the review. Full details of the study methodology can be found on Prospero, a systematic review register. Five studies satisfied our eligibility criteria: three reporting on acupuncture, one on homeopathy, and one on acupoints. Acupoint pressure was the only study that demonstrated reduced pain compared with placebo. This study was the least methodologically robust. Arnica, although demonstrating a significant reduction in swelling, did not affect post-operative pain. Acupuncture did not affect post-operative pain; however, a reduction in ibuprofen use was demonstrated in two studies. Before recommending complementary therapy for routine use in ambulatory knee surgery, further work is required. Two areas of future research likely to bear fruit are demonstrating robust evidence for the effect of acupoint pressure on post-operative pain, and quantifying the positive effect of homeopathic arnica on post-operative swelling.

This study was designed to investigate whether stepwise tapering of remifentanil at the end of surgery could decrease postoperative pain scores and requirements of rescue analgesics after remifentanil-desflurane anesthesia in patients with thyroidectomy. Sixty two patients undergoing thyroidectomy under general anesthesia were randomly allocated into two groups. All patients were anesthetised with desflurane and high-dose remifentanil. Remifentnail was infused at the rate of 0.3 μg/kg/min until the end of surgery in patients of the control group (group A) whereas remifentanil was tapered gradually from 0.3 to 0.1 μg/kg/min until the end of surgery for at least 30 minutes in patients with group B. Pain scores (0-100 numerical rating scale, NRS), rescue analgesic requirements and adverse events were assessed at 30 min, 2 h, 6 h, 12 h, and 24 h after operation. There was a significant decrease in pain scores at 30 min (20 [0-80] vs. 50 [0-100], P = 0.002) and 2 h (30 [10-60] vs. 40 [20-80], P = 0.018) after surgery in group B compared with group A. In addition, rescue analgesics are less required in group B than in group A postoperatively (2 [1-3] vs. 3 [2,3], P = 0.039). There were no significant differences in adverse events between the two groups. Tapering of remifentanil at the end of surgery decreased postoperative pain scores immediately after thyroidectomy with desflurane and high-dose remifentanil anesthesia.

The objective of this study was to compare the safety, difficulty of removal, and postoperative pain profile of radiofrequency ablation versus standard electrocautery removal of tonsils. A prospective, blinded study was designed to remove 1 tonsil with each of the 2 methods. Time of operation, estimated blood loss, difficulty of operation, postoperative pain, rate of postoperative hemorrhage, and the patient's preferred technique were evaluated. The operating time was significantly longer (P < 0.007) and the patients reported significantly less pain (P < 0.001) with radiofrequency ablation. There were no differences in blood loss, difficulty of operation, or postoperative hemorrhage rates. The patients preferred the radiofrequency ablation technique (P < 0.001). Radiofrequency ablation is a viable method to remove tonsillar tissue. Operating time for this procedure will likely decrease with experience. There was significantly less pain reported with radiofrequency ablation compared with standard electrocautery.

Objectives Unlike information provided for research, information disclosed to patients for treatment or procedures is largely unregulated and, as such, there is likely considerable variability in the type and amount of disclosure. This study was designed to examine the nature of information provided to parents regarding options for postoperative pain control and their understanding thereof. Methods 187 parents of children scheduled to undergo a surgical procedure requiring inpatient postoperative pain control completed questionnaires that elicited information regarding their perceptions and understanding of, and satisfaction with, information regarding postoperative pain management. Results Results showed that there was considerable variability in the content and amount of information provided to parents based on the method of postoperative pain control provided. Parents whose child received Patient Controlled Analgesia (PCA) were given significantly (P< 0.025) more information on the risks and benefits compared to those receiving Nurse Controlled or intravenous-prn (NCA or IV) analgesia. Approximately one third of parents had no understanding of the risks associated with postoperative pain management. Parents who received pain information preoperatively and who were given information regarding the risks and benefits had improved understanding compared to parents who received no or minimal information (P< 0.001). Furthermore, information that was deemed unclear or insufficient resulted in decreased parental understanding. Discussion These results demonstrate the variability in the type and amount of information provided to parents regarding their child’s postoperative pain control and reinforce the importance of clear and full disclosure of pain information, particularly with respect to the risks and benefits.

It is reported that ketamine, a N-methyl-D-aspertate (NMDA) receptor antagonist, can provide analgesic effect improving postoperative pain management and decrease the supplementary analgesic requirement. We investigated the analgesic sparing effect of ketamine for postoperative pain in children undergoing surgery of body surface. Fifty eight patients (0-9 yrs) who had surgery of body surface were divided into two groups (ketamine : n = 27, Group K or control : n = 31, Group N). Postoperative analgesia extracted from charts was retrospectively evaluated by the times patients used analgesics until discharge after the operations. Chi-square and Mann-Whitney U tests were used for statistical analysis. Results : The ketamine group received an intrave- nous bolus of ketamine (1 mg - kg-1) before surgical skin incision. However, there were no significant differ- ences of usage (Group K vs Group N : 4/27 vs 7/31, P=0.45) and frequency of supplementary analgesic us- ages (P=0.85) among groups. In addition, there were also no significant demographic differences between the two groups. Conclusions : Our investigation suggests that the intravenous bolus of ketamine (1 mg - kg-1) before surgical skin incision does not decrease the supple- mentary analgesic requirements on postoperative pain management in pediatric surgery of the body surface.

Paracervical block is used as a way to decrease postoperative pain in patients having abortions under general anesthesia. To date, no studies have evaluated the efficacy of this practice. Patients were recruited from a university-based family planning clinic. Seventy-two patients seeking abortion under general anesthesia were enrolled into the single-blinded study. Thirty-nine patients were randomized to receive a paracervical block, and 33 were randomized to no local anesthesia. The patients completed a demographic survey and visual analog pain scales for pain prior to and at several time points after the procedure. Data regarding the need for additional pain medications postoperatively were recorded. Analysis of variance single factor and two-sample one-sided t test were used in data analysis. Experimental and control groups were similar in all measured demographic characteristics. They were also similar in gestational age, number of laminaria required, preoperative dilation, operative time, estimated blood loss and reported complications. Postoperative pain was not significantly affected by placement of a paracervical block prior to abortion under general anesthesia. The need for postoperative pain medication during recovery was similar between groups. This study does not support the hypothesized benefit of local anesthesia prior to surgical abortion under general anesthesia to reduce postoperative pain.

Perioperative pain reduction, particularly during the first two days, is highly important for patients after total knee arthroplasty (TKA). Problems are not only caused by medical issues but by organization and hospital structure. The present study shows how the quality of pain management can be increased by implementing a standardized pain concept and simple, consistent benchmarking. All patients included into the study had undergone total knee arthroplasty. Outcome parameters were analyzed by means of a questionnaire on the first postoperative day. A multidisciplinary team implemented a regular procedure of data analyzes and external benchmarking by participating in a nationwide quality improvement project. At the beginning of the study, our hospital ranked 16 th in terms of activity-related pain and 9 th in patient satisfaction among 47 anonymized hospitals participating in the benchmarking project. At the end of the study, we had improved to 1 st activity-related pain and to 2 nd in patient satisfaction. Although benchmarking started and finished with the same standardized pain management concept, results were initially pure. Beside pharmacological treatment, interdisciplinary teamwork and benchmarking with direct feedback mechanisms are also very important for decreasing postoperative pain and for increasing patient satisfaction after TKA.

Effective postoperative pain management after shoulder arthroscopy is a critical component to recovery, rehabilitation, and patient satisfaction. This systematic review provides a comprehensive overview of level 1 and level 2 evidence regarding postoperative pain management for outpatient arthroscopic shoulder surgery. Systematic review. We performed a systematic review of the various modalities reported in the literature for postoperative pain control after outpatient shoulder arthroscopy and analyzed their outcomes. Analgesic regimens reviewed include regional nerve blocks/infusions, subacromial/intra-articular injections or infusions, cryotherapy, and oral medications. Only randomized control trials with level 1 or level 2 evidence that compared 2 or more pain management modalities or placebo were included. We excluded studies without objective measures to quantify postoperative pain within the first postoperative month, subjective pain scale measurements, or narcotic consumption as outcome measures. A combined total of 40 randomized control trials met our inclusion criteria. Of the 40 included studies, 15 examined nerve blocks, 4 studied oral medication regimens, 12 studied subacromial infusion, 8 compared multiple modalities, and 1 evaluated cryotherapy. Interscalene nerve blocks (ISBs) were found to be the most effective method to control postoperative pain after shoulder arthroscopy. Increasing concentrations, continuous infusions, and patient-controlled methods can be effective for more aggressively controlling pain. Dexamethasone, clonidine, intrabursal oxycodone, and magnesium have all been shown to successfully improve the duration and adequacy of ISBs when used as adjuvants. Oral pregabalin and etoricoxib administered preoperatively have evidence supporting decreased postoperative pain and increased patient satisfaction. On the basis of the evidence in this review, we recommend the use of ISBs as the most effective analgesic for outpatient arthroscopic shoulder surgery.

Groin pain following a transobturator (TO) midurethral sling is not uncommon and can be difficult to manage. We sought to determine if decreasing the mesh burden in the groin would decrease pain. The primary objective was to compare the incidence of post-operative groin pain following placement of full-length TVT-Obturator versus the shorter TVT-Abbrevo. Secondarily, we aimed to compare the efficacy between both devices 6 months after surgery. This is a retrospective cohort study of all women who underwent a TO midurethral sling by the division of urogynecology at one institution between 1 January 2007 and 31 October 2013. Charts were reviewed and the incidence of post-operative groin pain in the two groups dichotomized as present or absent and compared using a Chi-squared test. Validated questionnaire scores of the groups were compared using t tests. There were 125 patients who received a TVT-Obturator and 100 patients who received a TVT-Abbrevo. No differences in demographic data were present between the groups. Twelve patients (9.6 %) in the TVT-Obturator group and 1 patient (1 %) in the TVT-Abbrevo group experienced bothersome groin pain (P value = 0.007). The complete pre- and 6-month post-operative ISI, UDI-6 and PFIQ-7 scores were available for 76 (61 %), 47 (38 %), and 45 (36 %) patients following TVT-Obturator and 57 (57 %), 30 (30 %), and 28 (28 %) following TVT-Abbrevo treatment. At 6 months the mean improvement in questionnaire scores for the TVT-Obturator and TVT-Abbrevo groups were as follows: 5.0 and 5.1 for ISI (P value = 0.9), 8.3 and 7.9 for UDI-6 (P value = 0.8), and 4.8 and 6.1 for PFIQ-7 (P value = 0.4). Use of TVT-Abbrevo reduces post-operative groin pain compared with the full-length TVT-Obturator, without any reduction in efficacy.

Pain management after total hip arthroplasty (THA) varies and has been widely studied in recent years. Gabapentin as a third-generation antiepileptic drug that selectively affects the nociceptive process has been used for pain relief after THA. This meta-analysis was conducted to examine the efficacy of gabapentin in THA. An electronic-based search was conducted using the following databases: PubMed, EMBASE, Ovid MEDLINE, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL). Randomised controlled trials (RCTs) involving gabapentin and a placebo for THA were included. The meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Five trials met the inclusion criteria. The cumulative narcotic consumption and the visual analogue scale (VAS) scores at 24 and 48 h postoperatively were used for postoperative pain assessment. There was a significant decrease in morphine consumption at 24 h (P = 0.00). Compared with the control group, the VAS score (at rest) at 48 h was less in the gabapentin group (P = 0.00). The administration of gabapentin is effective in decreasing postoperative narcotic consumption and the VAS score.

Approximately half of all patients who undergo surgery develop postoperative pain, the mechanisms of which are not well understood by anesthesiologists. D2-like receptors in the descending dopaminergic pathway play an important role in regulation of pain transmission in the spinal cord. Impairment of inhibitory neurons in the spinal cord is suggested as part of the mechanism for neuropathic pain, which is one component of postoperative pain. The purpose of this study was to investigate whether impairment of D2-like receptors in the descending dopaminergic pathway in the spinal cord is involved in the decreased postoperative nociceptive threshold in rats. Male Sprague-Dawley rats (250-300 g) were anesthetized with sevoflurane and an intrathecal (IT) catheter was implanted. Six days later, a plantar incision was made. On the following day, saline, a D2-like receptor agonist (quinpirole), or a D2-like receptor antagonist (sulpiride) was administered intrathecally. Thermal and mechanical nociceptive responses were assessed by exposure to infrared radiant heat and the von Frey filament test before and after plantar incision. Plantar incision decreased both thermal latency and the mechanical nociceptive threshold. IT administration of quinpirole inhibited the nociceptive responses induced by plantar incision, but sulpiride had no effect. A D2-like receptor agonist had antinociceptive effects on the hypersensitivity response triggered by a surgical incision, but a D2-like receptor antagonist had no effect on this response. These results suggest that impairment and/or modification of D2-like receptors in the descending dopaminergic pathway in the spinal cord is not involved in the postoperative decrease in nociceptive threshold.

The primary objective of the study was to determine if local infiltration anaesthetic (LIA) reduced total length of hospital stay in total knee arthroplasty (TKA) patients. The study also examined whether LIA improves early pain management, patient satisfaction and range of motion in TKA patients. We conducted a randomized controlled double-blinded study. Fifty patients undergoing TKA were randomized to receive either placebo or LIA at the time of surgery and on the first day post-operatively. Pain scores, level of satisfaction and range of motion were recorded preoperatively and post-operatively. There was no statistical difference between the groups for length of stay, post-operative pain scores, satisfaction scores or range of motion 6 weeks post-operatively. This randomized double-blinded trial did not demonstrate a decrease in pain or reduction of length of stay due to local infiltration analgesia. © 2015 Royal Australasian College of Surgeons.

To identify behavioral alterations in client-owned cats recovering at home following elective ovariohysterectomy or castration and determine owner perceptions regarding severity of postoperative pain. Cohort study. Animals-145 cats undergoing elective ovariohysterectomy (n = 80) or castration (65) at 4 veterinary clinics in Finland. Owners were asked to complete a questionnaire on their cats' behavior during the 3 days after surgery. Owners were also asked to indicate their perceptions of the severity of postoperative pain during these days by use of a 100-mm visual analog scale. Owners consistently indicated that there were changes in their cats' behavior, with the most commonly reported alterations being a decrease in overall activity level, an increase in the amount of time spent sleeping, a decrease in playfulness, and altered way of movement. Changes (ie, either an increase or decrease) in aggressive behavior were rare. Median pain score the day of surgery was 15.0 mm for male cats and 25.0 mm for female cats. Behavior score was significantly associated with day of observation, type of surgery (ovariohysterectomy vs castration), owner-assigned pain score, and veterinary clinic. Results suggested that behavioral alterations can be detected for several days after surgery in cats recovering at home following ovariohysterectomy or castration and emphasized owner concerns about the existence of postoperative pain.

Parecoxib, a prodrug of valdecoxib, a selective COX-2 inhibitor, has been recently introduced for the treatment of moderate to severe postoperative pain. This prospective, open, multicentric study enrolled 260 patients undergoing orthopaedic, gynaecological, dental and general surgery. Postoperatively, patients were treated with parecoxib, 40 mg IM/IV. There was a statistically significant decrease in the mean pain intensity score (p<0.05). At the end of 24 hours, 89.6% of total cases had a very good to total relief of pain. The mean duration of analgesia was 19.26 hours and mean time of onset of analgesia was 16.25 minutes ranging from 11-20 minutes. The laboratory values were within normal limits. The drug was well tolerated. There was no report of any hypersensitivity reaction. This study suggests that parecoxib, in a dose of 40 mg IM/IV, is an effective and safe option for the management of postoperative pain.

Our institution's traditional pain management strategy after shoulder arthroplasty has involved the utilization of postoperative patient-controlled narcotic analgesia. More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. Patients undergoing primary total shoulder or reverse arthroplasty were retrospectively studied. All patients underwent interscalene brachial plexus blockade. "Traditional" patients were provided a patient-controlled analgesic pump postoperatively. TLC patients were given preoperative and postoperative multimodal, non-narcotic analgesic medications and breakthrough narcotics. Morphine equivalent units (MEU) consumed and Visual Analog Scale (VAS) scores for pain (0, 8, 16, and 24 hours) were considered. There were 108 patients in each group. Total postoperative narcotic consumption in the first 24 postoperative hours was 38.5 +/- 81.1 MEU in the "Traditional group" compared to 59.3 +/- 59.1 MEU in the TLC group ( P<0.001 ). Of patients in the TLC group, 88% utilized breakthrough narcotics. VAS pain was significantly higher in the "Traditional group" at 16 hours (4.1 +/- 2.9 vs 3.2 +/- 2.7, P=0.020 ) and 24 hours (4.8 +/- 2.7 vs 3.7 +/- 2.6, P=0.004 ). Those treated with the TLC protocol had greater narcotic utilization but better VAS pain scores at 24 hours after surgery. Both groups experienced rebound pain. While the TLC protocol led to an improved pain experience, further modification of the currently protocol may be necessary to reduce overall narcotic utilization.

Transcutaneous electrical nerve stimulation (TENS) has been applied for pain relief after surgical procedures. This study evaluated whether TENS after video-assisted thoracoscopic surgery (VATS), in addition to opioid administration, decreased postoperative pain and pain medication use. In a controlled trial, 56 patients scheduled to undergo VATS were randomly assigned to TENS plus opioids (Group 1) or opioids alone (Group 2) for 48 h. Forty patients completed the study. Pain scores and use of oral morphine equivalents (OMEs) were not significantly different between the groups during the first and second 24 h. A decreased use of OMEs between the first and second 24 h was significant for Group 1 (P = .005) but not for Group 2 (P = .11); a decreased use of OMEs between groups was not significant (P = .35). A larger, well-powered clinical trial is indicated to evaluate the effects of TENS for pain control after a VATS procedure. Clinical Trial No.: NCT01046695. Crown Copyright © 2015.

Pain Management Strategies in Shoulder Arthroplasty.

PubMed

Codding, Jason L; Getz, Charles L

2018-01-01

Pain control in total shoulder arthroplasty demands a multidisciplinary approach with collaboration between patients, surgeon, and anesthetist. A multimodal approach with preemptive medication, regional blockade, local anesthetics, and a combination of acetaminophen, nonsteroidal antiinflammatory drugs, tramadol, and gabapentinoids postoperatively leads to pain control and patient satisfaction. Assessment of patients' expectations constitutes a vital aspect of the preoperative patient evaluation. Educating and psychologically preparing patients reduces postoperative pain. Patients with anxiety and depression, preoperative narcotic use, and medical comorbidities are at an increased risk for suboptimal pain control. Minimizing narcotic use decreases opioid-related adverse effects and facilitates productive rehabilitation efforts. Copyright © 2017 Elsevier Inc. All rights reserved.

The utilization of peripheral nerve blocks in orthopaedic surgery has paralleled the rise in the number of ambulatory surgical procedures performed. Optimization of pain control in the perioperative orthopaedic patient contributes to improved patient satisfaction, early mobilization, decreased length of hospitalization, and decreased associated hospital and patient costs. Our purpose was to provide a concise, pertinent review of the use of peripheral nerve blocks in various orthopaedic procedures of the lower extremity, with specific focus on procedural anatomy, indications, patient outcome measures, and complications. We reviewed the literature and reference textbooks on commonly performed lower-extremity peripheral nerve block procedures in orthopaedic surgery, focusing on those most commonly used. The use of lower-extremity peripheral nerve blocks is a safe and effective approach to perioperative pain management. Different techniques and timing can have an important impact on patient satisfaction, and each technique has specific indications and complications. For major hip surgery, one of the most commonly used is the lumbar plexus block, which can result in early mobilization, reduced postoperative pain, and decreased opioid-associated adverse events. Associated complications include epidural spread of anesthesia, retroperitoneal hematoma formation, and postoperative falls. For arthroscopic and open knee procedures, the femoral nerve block is frequently used adjunctively. It provides improved early postoperative pain control, early mobilization with therapy, and increased patient satisfaction compared with intra-articular or intravenous opioids alone; it also provides cost savings. However, some studies have shown no significant difference in outcome measures compared with intra-articular opioids alone for arthroscopic anterior cruciate ligament reconstruction. Associated complications include nerve injury, intravascular injection, and postoperative falls. The use of peripheral nerve blocks in lower-extremity surgery is becoming a mainstay of perioperative pain management strategy.

We evaluated the efficacy of dexpanthenol in managing pediatric post-tonsillectomy pain and wound healing and sought to discover which of two surgical tonsillectomy techniques provides better healing and less postoperative pain. One hundred twenty patients who underwent tonsillectomy were equally randomized to thermal welding and cold dissection groups. Dexpanthenol pastilles were given to half of each group. Postoperative throat pain was determined with a visual analog scale on the 1st, 3th, 7th, and 14th days, and mucosal healing patterns were assessed on the 7th and 14th days. Regardless of surgical technique, post-tonsillectomy throat pain was significantly less in the dexpanthenol groups than in the placebo groups (p < 0.05), and tonsillar wound healing was significantly better in the dexpanthenol groups than in the placebo groups (p < 0.05). When a comparison was made with regard to surgical technique, wound healing was significantly better in the cold dissection group (p < 0.05), whereas postoperative throat pain was less in the thermal welding group (p < 0.05). Postoperative administration of dexpanthenol significantly accelerates the wound healing process and decreases tonsillectomy-related pain complaints.

The United States is in a prescription opioid crisis. Orthopedic surgeons prescribe more opioid narcotics than any other surgical specialty. The purpose of this study was to evaluate the state of opioid use after extremity trauma in orthopedic surgery. A computerized literature search of PubMed/MEDLINE was conducted to evaluate the status of opioids after extremity fractures. Six articles were identified and included in the review. Patients who consume more opioids communicate greater pain intensity and less satisfaction with pain control. Intraoperative multimodal drug injection and nerve blockade are viable alternatives for postoperative pain control and can help decrease systemic opioid use. Orthopedic surgeons are overprescribing opioids. Compared to other countries, the United States consumes more opioids with no better satisfaction with pain control. Orthopedic trauma surgeons should tailor their postoperative opioid prescriptions to the individual patient and utilize alternative options in order to control postoperative pain. Patients should be counseled regarding narcotic addiction and dependence. Patients unable to manage pain postoperatively should be followed closely and receive the proper chronic pain management, mental and social health services referrals. Copyright © 2018 Elsevier Ltd.

This prospective, single-center, single-blind, randomized controlled trial aimed to evaluate whether maintaining apical patency (AP) during endodontic treatment increases postoperative pain in molar teeth with necrotic pulp and apical periodontitis. Three hundred twenty qualified patients between 21 and 45 years of age were randomized into 1 of 2 groups (the AP group and the nonapical patency [NAP] group) using a series of random numbers in a 1:1 ratio. Qualified patients were selected from patients who had necrotic pulp and apical periodontitis in the maxillary or mandibular molar teeth. The primary outcome was to assess postoperative pain severity, and the secondary outcome was to evaluate analgesic consumption during the 7-day follow-up period using the visual analog scale (VAS). The VAS consisted of a 100-mm line. Pain severity was evaluated as no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm). The Student t test was used to identify statistically significant differences between the study groups (P < .05). The mean VAS scores were significantly lower in the AP group in the first 5 postoperative days (P < .05); after which, it was nonsignificant. In the NAP group, the postoperative pain increased between 12 and 24 hours, whereas the postoperative pain decreased in the AP group during that period. At 12 and 24 hours, the mean VAS scores for the AP group were 42.90 and 37.78 mm, respectively. The mean VAS scores for the NAP group were 64.46 and 65.74 mm, respectively. None of the patients had severe postoperative pain during the follow-up period. No significant difference was found in analgesic consumption (P > .05) between the groups. The maintenance of AP in molar teeth with necrotic pulp and apical periodontitis was associated with less postoperative pain when compared with NAP.

Minimally invasive laparoscopy provides faster recovery, less pain, fewer complications, and better cosmesis than laparotomy. We aimed to evaluate outcomes of postoperative local anesthesia infiltration at the single-incision laparoscopic surgery (SILS) wound. This prospective, non-randomized controlled study evaluated outcomes of 58 colorectal cancer cases receiving SILS from May 2010 to December 2010. Twenty-nine patients received postoperative infiltration of local anesthesia at the wound site; another 29 patients did not. Demographic, intra- and postoperative data were compared. Postoperative pain was assessed by visual analogue scale and analgesic usage. Local anesthesia group included 16 males, 13 females (mean age, 62.0 ± 15.1 years); no local anesthesia group included 14 males, 15 females (mean age, 58.1 ± 12.7 years). There were no significant differences between groups at baseline (i.e., age, gender, disease stage, tumor location or size) except BMI (25.2 ± 2.8 vs. 23.5 ± 3.4, p = 0.041) was significantly higher. Postoperative pain scores were significantly lower in local anesthesia group than in no local anesthesia group (median VAS score 2.0, IQR 2.0-3.0 vs. VAS score 3.0, IQR 3.0-4.0, respectively, P = 0.024). Our results provide further evidence of SILS safety. Local anesthesia infiltration at SILS wounds decreases postoperative wound pain and analgesic usage.

Chronic stress has been reported to increase basal pain sensitivity and/or exacerbate existing persistent pain. However, most surgical patients have normal physiological and psychological health status such as normal pain perception before surgery although they do experience short-term stress during pre- and post-operative periods. Whether or not this short-term stress affects persistent postsurgical pain is unclear. In this study, we showed that pre- or post-surgical exposure to immobilization 6 h daily for three consecutive days did not change basal responses to mechanical, thermal, or cold stimuli or peak levels of incision-induced hypersensitivity to these stimuli; however, immobilization did prolong the duration of incision-induced hypersensitivity in both male and female rats. These phenomena were also observed in post-surgical exposure to forced swimming 25 min daily for 3 consecutive days. Short-term stress induced by immobilization was demonstrated by an elevation in the level of serum corticosterone, an increase in swim immobility, and a decrease in sucrose consumption. Blocking this short-term stress via intrathecal administration of a selective glucocorticoid receptor antagonist, RU38486, or bilateral adrenalectomy significantly attenuated the prolongation of incision-induced hypersensitivity to mechanical, thermal, and cold stimuli. Our results indicate that short-term stress during the pre- or post-operative period delays postoperative pain recovery although it does not affect basal pain perception. Prevention of short-term stress may facilitate patients' recovery from postoperative pain.

Abstract Background: Robotic cholecystectomy (RC) using port sites in the lower abdominal area (T12-L1) rather than the upper abdomen has recently been introduced as an alternative procedure for laparoscopic cholecystectomy. Therefore, we investigated the time course of different components of pain and the analgesic effect of the bilateral ultrasound-guided split injection technique for rectus sheath block (sRSB) after RC in female patients. Methods: We randomly assigned 40 patients to undergo ultrasound-guided sRSB (RSB group, n = 20) or to not undergo any block (control group, n = 20). Pain was subdivided into 3 components: superficial wound pain, deep abdominal pain, and referred shoulder pain, which were evaluated with a numeric rating scale (from 0 to 10) at baseline (time of awakening) and at 1, 6, 9, and 24 hours postoperatively. Consumption of fentanyl and general satisfaction were also evaluated 1 hour (before discharge from the postanesthesia care unit) and 24 hours postoperatively (end of study). Results: Superficial wound pain was predominant only at awakening, and after postoperative 1 hour in the control group. Bilateral ultrasound-guided sRSB significantly decreased superficial pain after RC (P < 0.01) and resulted in a better satisfaction score (P < 0.05) 1 hour after RC in the RSB group compared with the control group. The cumulative postoperative consumption of fentanyl at 6, 9, and 24 hours was not significantly different between groups. Conclusions: After RC with lower abdominal ports, superficial wound pain predominates over deep intra-abdominal pain and shoulder pain only at the time of awakening. Afterwards, superficial and deep pain decreased to insignificant levels in 6 hours. Bilateral ultrasound-guided sRSB was effective only during the first hour. This limited benefit should be balanced against the time and risks entailed in performing RSB. PMID:27495072

Narrow band imaging cystoscopy can increase the visualization and detection of Hunner's lesions. A single-center, prospective clinical trial was carried out aiming to show the effectiveness of narrow band imaging-assisted transurethral electrocoagulation for ulcer-type interstitial cystitis/painful bladder syndrome. A total of 23 patients (19 women and 4 men) diagnosed as having ulcer-type interstitial cystitis/painful bladder syndrome were included. All typical Hunner's lesions and suspected areas identified by narrow band imaging were electrocoagulated endoscopically after the biopsy of those lesions. Therapeutic efficacy was assessed prospectively by using visual analog scale score of pain, O'Leary-Sant's symptom index, O'Leary-Sant's problem index and overactive bladder symptom score. The mean follow-up period was 22 months. All patients (100%) experienced a substantial improvement in pain. The average visual analog scale pain scores significantly decreased from 7.3 preoperatively to 1.2 1 month postoperatively. A total of 21 patients (91.3%) who reported improvement had at least a 50% reduction in bladder pain, and five reported complete resolution. Daytime frequency was significantly decreased postoperatively. O'Leary-Sant's symptom index, O'Leary-Sant's problem index and overactive bladder symptom score were significantly decreased postoperatively. However, during the follow-up period, a total of six patients had recurrence, and repeat narrow band imaging-assisted transurethral electrocoagulation of the recurrent lesions was carried out for five of the six patients, with good response in relieving bladder pain. Our results showed that narrow band imaging-assisted transurethral electrocoagulation could be a valuable therapeutic alternative in patients with ulcer-type interstitial cystitis/painful bladder syndrome, with good efficacy and reduction of recurrence rate. © 2014 The Japanese Urological Association.

This study compared the analgesic efficacy of postoperative tramadol versus ketamine for preventing pain after mandibular molar extraction. Ninety patients who had undergone molar extraction were randomly divided into 3 groups: group T (tramadol 1 mg/kg), group K (ketamine 0.5 mg/kg), and group P (saline 2 mL). The treatment was applied to the extraction sockets using resorbable gelatin sponges. Pain after extraction was evaluated using a visual analog scale (VAS) 0.5, 1, 2, 4, 6, 12, 24, and 48 hours postoperatively. The VAS scores after extraction were statistically higher in group P than in either treatment group. Group K had the lowest pain intensity. This study shows that topical tramadol and ketamine are effective alternatives for decreasing pain after molar extractions. Copyright © 2015 American Association of Oral and Maxillofacial Surgeons.

Tramadol is a centrally acting weak μ opioid agonist that has few of the adverse side effects common to other opioids. Little work has been done to establish an effective analgesic dose of tramadol specific for surgical laparotomy and visceral manipulation in mice. We used general appearance parameters to score positive indicators of pain including posture, coat condition, activity, breathing, and interactions with other mice, activity events (that is, the number of times each mouse stretched up in a 3-min period) used as an indicator of decreased pain, von Frey fibers, and plasma levels of corticosterone to determine whether tramadol at 20, 40, or 80 mg/kg prevented postoperative pain in male and female C57BL/6 mice. A ventral midline laparotomy with typhlectomy was used as a model of postoperative pain. In male mice, none of the markers differed between groups that received tramadol (regardless of dose) and the saline-treated controls. However, general appearance scores and plasma corticosterone levels were lower in female mice that received 80 mg/kg tramadol compared with saline. In summary, for severe postoperative pain after laparotomy and aseptic typhlectomy, tramadol was ineffective in male C57BL/6 mice at all doses tested. Although 80 mg/kg ameliorated postoperative pain in female C57BL/6 mice, this dose is very close to the threshold reported to cause toxic side effects, such as tremors and seizures. Therefore, we do not recommend the use of tramadol as a sole analgesic in this mouse model of postoperative pain. PMID:26224442

Although not completely painless, breast-conserving surgery is considerably less painful than modified radical mastectomy. Local anesthetics are speculated to reduce postoperative pain when placed at the surgical site. Thus, we conducted a systematic review of randomized controlled trials to evaluate the efficacy of bupivacaine or ropivacaine analgesia for pain relief in breast cancer surgery. PubMed, Embase, the Cochrane Library, Scopus, and the ClinicalTrials.gov registry were searched for studies published up to July 2015. Individual effect sizes were standardized, and a meta-analysis was performed to calculate a pooled effect size by using random effects models. Pain was assessed using a visual analog scale at 1, 2, 12, and 24 h postoperatively. The secondary outcomes included complications and analgesic consumption. We reviewed 13 trials with 1150 patients. We found no difference in postoperative pain reduction at 1, 12, and 24 h after breast cancer surgery between the experimental and control groups. The severity of pain was significantly reduced in the experimental group (weighted mean difference -0.19; 95% confidence interval: -0.39-0.00) at 2 h postoperatively. Moreover, postoperative analgesic consumption did not differ significantly between the groups. No major drug-related complication was observed in any study. Administration of the local anesthetics bupivacaine or ropivacaine during breast cancer surgery decreased pain significantly at only 2 h but did not reduce pain at 12, and 24 h postoperatively.

Kinesio-Taping(®) (K-Tape) is used in sports traumatology with the aim of reducing pain and improving blood and lymph circulation. The main objective of the present study was to assess the efficacy of K-Tape on early postoperative pain after anterior cruciate ligament (ACL) reconstruction. The study hypothesis was that K-Tape significantly decreases pain. A prospective non-randomized comparative study was conducted in 2013-2014 and included all patients who underwent primary ACL reconstruction by hamstring graft. Analgesia was standardized. Two groups, "K-Tape" and "controls", were formed according to the days on which the study physiotherapist was present. The K-Tape compression/decompression assembly was applied immediately postoperatively and maintained for 3days. Patients filled out online questionnaires. The main assessment criterion was mean postoperative pain (D0-D3) on a 0-to-10 scale. Secondary criteria were analgesia intake on the three WHO levels, awakening during the night of D0 due to pain, signs of postoperative discomfort, and patient satisfaction. Sixty patients (30 per group) were included, 57 of whom could be assessed: 28 K-Tape, 29 controls; 44 male, 13 female; mean age, 30.9±8.9 years. At inclusion, the two groups were comparable. There was no significant difference in mean (D0-D3) knee pain intensity: 3.8±2.2 for K-Tape, and 3.9±2 for controls (P=0.93). Analysis of variance (ANOVA) found no significant intergroup difference in evolution of pain (P=0.34). There were no other significant differences on the other assessment criteria. K-Tape showed no efficacy on early postoperative pain following ACL reconstruction. III; prospective non-randomized comparative study. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

The number of total knee replacements performed each year is increasing. Among the main impediments to functional recovery after these surgeries include postoperative edema, pain, lower limb muscle strength deficits, all of which point to a need to identify safe, effective postoperative rehabilitation modalities. The aim of this paper was to evaluate the effectiveness of Kinesio Taping® (KT) method in reducing postoperative pain, edema, and improved knee range of motion recovery after total knee replacement (TKR) operation in early postoperative rehabilitation period. Randomized clinical trial. Inpatient rehabilitation facility. Ninety-four patients, who underwent primary TKR surgery. Using simple randomization, participants were divided into KT group and control group. Both groups received same rehabilitation program and procedures after surgery, except KT group also received KT applications throughout all rehabilitation period. Postoperative pain, edema, restoration of the operated knee flexion and extension were evaluated. The chosen level of significance was P<0.05; in evaluation power of the test β ≤ 0.2. Groups were homogenous to sex, age, BMI, comorbidities, preoperative knee flexion/extension impairment, preoperative pain intensity, anaesthesia, prosthesis implanted (P>0.05). In both groups postoperative pain decreased significantly during rehabilitation period, however less pain was found in KT group from the second postoperative week till the end of inpatient rehabilitation (28th postoperative day) (P<0.05; β ≤ 0.2). Postoperative edema was less intense and subsided more quickly in KT group as well (P<0.05; β ≤ 0.2). No difference was found in improvement of knee flexion (P>0.05). Operated knee extension was found better in KT group then in control at the end of in-patient rehabilitation (P<0.05; β ≤ 0.2). KT was well tolerated by patients. KT technique appeared to be beneficial for reducing postoperative pain, edema, improving knee extension in early postoperative rehabilitation period. This finding implies for health care professionals working in the field of physical medicine and rehabilitation that Kinesio Taping® method is safe and can be used as additional rehabilitation means for patients after TKR.

Intravenous patient-controlled opioid analgesia has been an important improvement in addressing insufficient management of acute postoperative pain for over 40 years. However, there are number of weaknesses for intravenous patient-controlled analgesia, including operator and device error, intravenous line patency issues, and risk of catheter-related infection, all of which contribute to the complications and increase in cost of care. The sublingual sufentanil tablet system is a major evolution in both drug and technological management of postoperative pain. Areas covered: We reviewed the use of the sublingual sufentanil tablet system in management of moderate to severe postoperative pain in hospitalized patients, with a particular focus on the pharmacological properties of sufentanil and clinical use in different surgical patients. Expert opinion: The sublingual sufentanil tablet system can decrease intravenous opioid based patient-controlled analgesia related complications and safety issues. Current clinical studies have demonstrated this noninvasive-novel system to be safe and effective in management of acute pain in the postsurgical setting. Researchers should focus on comparing it with other available patient controlled analgesia modalities and evaluating the efficiency and cost effectiveness of the sublingual sufentanil tablet system.

Pain is a normal finding in the postoperative patient, and noise can accentuate one's perception of discomfort. In this study, physiological measurements, intravenous (IV) opioid administration, length of stay, and satisfaction for postoperative patients who listened to music were compared with patients not provided music during their PACU stay. Of the 213 subjects enrolled, 163 experienced postoperative pain. The mean change in experimental subjects' respiratory rate was significantly lower than the controls. Decreases in heart rate and blood pressure from admission to discharge were similar between the two groups. On average, peripheral oxygen saturation and opioid pain control were not significantly different between control and experimental subjects. Subjects provided with music reported acceptable noise levels and increased satisfaction with their PACU experience. Music intervention is therefore a viable, minimal cost, and alternative therapy that PACU nurses can use to assist patients coping with postoperative pain.

Tong, Yi Cai Isaac; Kaye, Alan David; Urman, Richard D

2014-03-01

In the multimodal approach to the management of postoperative pain, local infiltration and regional blocks have been increasingly utilized for pain control. One of the limitations of local anesthetics in the postoperative setting is its relatively short duration of action. Multivesicular liposomes containing bupivacaine have been increasingly utilized for their increased duration of action. Compared with bupivacaine HCl, local infiltration of liposomal bupivacaine has shown to have an increase in duration of action and causes delay in peak plasma concentration. In this article, we attempt to review the clinical literature surrounding liposomal bupivacaine and its evolving role in perioperative analgesia. This new bupivacaine formation may have promising implications in postoperative pain control, resulting in increased patient satisfaction and a decrease in both hospital stay and opioid-induced adverse events (AEs). Although more studies are needed, the preliminary clinical trials suggest that liposomal bupivacaine has predictable pharmacokinetics, a similar side effect profile compared with bupivacaine HCl, and is effective in providing increased postoperative pain control.

The surgical treatment of adult scoliosis frequently involves long segment fusions across the lumbosacral joints that redistribute tremendous amounts of force to the remaining mobile spinal segments as well as to the pelvis and hip joints. Whether or not these forces increase the risk of femoral bone pathology remains unknown. The aim of this study is to determine the correlation between long segment spinal fusions to the pelvis and the antecedent development of degenerative hip pathologies as well as what predictive patient characteristics, if any, correlate with their development. A retrospective chart review of all long segment fusions to the pelvis for adult degenerative deformity operated on by the senior author at the Duke Spine Center from February 2008 to March 2014 was undertaken. Enrolment criteria included all available demographic, surgical, and clinical outcome data as well as pre and postoperative hip pathology assessment. All patients had prospectively collected outcome measures and a minimum 2-year follow-up. Multivariable logistic regression analysis was performed comparing the incidence of preoperative hip pain and antecedent postoperative hip pain as a function of age, gender, body mass index (BMI), and number of spinal levels fused. In total, 194 patients were enrolled in this study. Of those, 116 patients (60%) reported no hip pain prior to surgery. Eighty-three patients (71.6%) remained hip pain free, whereas 33 patients (28.5%) developed new postoperative hip pain. Age, gender, and BMI were not significant among those who went on to develop hip pain postoperatively ( P < 0.0651, 0.3491, and 0.1021, respectively). Of the 78 patients with preoperative hip pain, 20 patients (25.6%) continued to have hip pain postoperatively, whereas 58 patients reported improvement in the hip pain after long segment fusion for correction of their deformity, a 74.4% rate of reduction. Age, gender, and BMI were not significant among those who continued to have hip pain postoperatively ( P < 0.4386, 0.4637, and 0.2545, respectively). Number of levels fused was not a significant factor in the development of hip pain in either patient population; patients without preoperative pain who developed pain postoperatively ( P < 0.1407) as well as patients with preoperative pain who continued to have pain postoperatively ( P < 0.0772). This study demonstrates that long segment lumbosacral fusions are not associated with an increase in postoperative hip pathology. Age, gender, BMI, and levels fused do not correlate with the development of postoperative hip pain. The restoration of spinal alignment with long segment fusions may actually decrease the risk of developing femoral bone pathology and have a protective effect on the hip.

Pain management after total knee arthroplasty (TKA) and total hip arthroplasty should permit early mobilization with minimal pain. Local infiltration analgesia (LIA) is a new popular method for decreasing postoperative pain. The goal of this meta-analysis is to evaluate the efficacy of LIA in comparison with epidural analgesia. A literature search was performed in PubMed, EMBASE, the OVID database, Web of Science, and the Cochrane Library databases. The risk of bias was assessed using the Cochrane collaboration tool. Outcomes of interest included visual analog scale score, range of flexion, length of stay, and complications. Nine trials involving 537 patients met the inclusion criteria. LIA provides better pain relief and larger range of motion in TKA patients compared to epidural analgesia at the late postoperative period. No significant difference was observed in regard to the length of stay and complications. The current evidence shows that the use of local infiltration is effective for postoperative pain management in TKA patients. More high-quality randomized controlled trials with long-term follow-up are required for examining the long-term efficacy and safety of local infiltration. PMID:27209072

To assess the analgesic efficacy of transversus abdominis plane (TAP) block in patients undergoing colorectal surgery (CRS). The databases of PubMed, ISI Web of Science, and Embase were searched, and randomized controlled studies (RCTs) that compared TAP block to control for relief of postoperative pain in patients who underwent CRS were included. Outcomes, including postoperative pain at rest and with movement, morphine use, postoperative nausea and vomiting, and the length of hospital stay, were analyzed using STATA software. The weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) or relative risk with 95% CI were used to present the strength of associations. A total of 7 RCTs with 511 patients were included. The results of this study suggested that TAP block significantly relieved postoperative pain during postanesthetic recovery after CRS at rest and during movement (WMDs were -0.98 [95% CI -1.57 to -0.38] and -0.68 [-1.07 to -0.30], respectively), and also decreased pain intensity during movement 24 h after CRS (WMD: -0.57 [95% CI -1.06 to -0.08]). TAP block significantly reduced opioid consumption within 24 h when compared to controls, with a WMD of 15.66 (95% CI -23.93 to -7.39). However, TAP block did not shorten the length of hospital stay. TAP block was an effective approach for relief of postoperative pain and reduced postoperative consumption of morphine. More RCTs with large sample sizes are required to confirm these findings. © 2018 The Author(s) Published by S. Karger AG, Basel.

Postoperative pain after total knee arthroplasty remains one of the most important challenges facing patients undergoing this surgery. Providing a balance of adequate analgesia while limiting the functional impact of regional anesthesia and minimizing opioid side effects is critical to minimize adverse events and improve patient satisfaction. We asked whether bupivacaine delivered through an elastomeric device decreases the (1) patients' perception of pain after TKA; (2) narcotic consumption; and (3) narcotic-related side effects as compared with a placebo. In this prospective, double-blind, placebo-controlled study, all patients received standardized regional anesthesia, a preemptive and multimodal analgesic protocol, and a continuous intraarticular infusion at 5 mL/hour through an elastomeric infusion pump. The patients were randomized to receive either an infusion pump filled with (1) 300 mL of 0.5% bupivacaine, the experimental group (n = 75); or (2) 300 mL of 0.9% normal saline solution, the control group (n = 75). Data concerning postoperative pain levels through a visual analog scale, postoperative opioid consumption, opioid-related side effects, and complications were collected and analyzed. Patients in the experimental group receiving the bupivacaine reported a reduction in pain levels in highest, lowest, and current visual analog scale scores compared with the placebo group on the first postoperative day and highest visual analog scale score on postoperative Day 2 along with a 33% reduction in opioid consumption on postoperative Day 2 and a 54% reduction on postoperative Day 3. In patients undergoing TKA, continuous intraarticular analgesia provided an effective adjunct for pain relief in the immediate postoperative period without the disadvantages encountered with other analgesic methods.

The knowledge of the influence of anesthetic techniques in postoperative outcomes has opened a large field of research in recent years. In this second part, we review some of the major controversies arising from the literature on the impact of anesthetic techniques on postoperative outcomes in 6 areas: postoperative cognitive dysfunction, chronic postoperative pain, cancer recurrence, postoperative nausea/vomiting, surgical outcomes, and resources utilization. The development of protective and preventive anesthetic strategies against short and long-term postoperative complications will probably occupy an important role in our daily anesthetic practice. Dynamic postoperative pain control has been confirmed as one of the basic requirements of accelerated postoperative recovery programs ("fast-track surgery"), and it is also a preventive factor for development of chronic postoperative pain. The weight of anesthetic technique on postoperative immunosuppression is to be defined. The potential influence of anesthesia on cancer recurrence, is a highly controversial area of research. The classic pattern of perioperative fluid therapy may increase postoperative complications. On the other hand, the maintenance of normoglycemia and normothermia was associated with a decreased postoperative morbidity. The high volume of surgical procedures means that the adequacy of human, organizational and technological resources have a major impact on overall costs.

Less is more: limiting narcotic prescription quantities for common orthopedic procedures.

PubMed

O'Neill, Daniel Fulham; Webb Thomas, Christopher

2014-11-01

Clinicians are now appreciating that the perception of pain is a multifaceted, biopsychosocial construct. Expectation of postsurgical pain is part of this construct and should be considered preoperatively. It is our belief that by establishing reasonable expectations with preoperative teaching, we can minimize narcotic use and lessen untoward issues that can potentially follow. With this goal in mind, we have been using a comprehensive pre- and postoperative program for our outpatient orthopedic surgery patients for the last 5 years, which includes physical, pharmacologic, and simple sport psychological techniques. We reviewed postoperative prescription narcotic purchases in 133 consecutive surgical patients during the last year (2013). All patients were given a prescription postoperatively for 10 hydrocodone 5-mg/acetaminophen 500-mg tablets, with 1 refill. We then contacted the patients' pharmacies to assess the actual amount purchased. Data were available for 100 patients. Of these, 62 patients had undergone "simple" arthroscopies and 38 had had "open" procedures, including 25 anterior cruciate ligament reconstructions, 4 tibial tubercle osteotomies, and various other surgeries. Of the 62 arthroscopies, 24 patients (39%) refilled their prescriptions, with 4 patients (6%) needing > 1 refill. Of the 38 open procedures, 16 patients (42%) refilled their medications, 2 (5%), more than once. Thus, 89% of patients required ≤ 20 narcotic tablets after undergoing common orthopedic operations. No patient needed chronic narcotic medication. Pain is a complex issue and patient expectation of postoperative pain is one aspect that can potentially affect the amount of narcotics used. By preparing the patient both physically and psychologically, we believe the amount of narcotics used postoperatively can be decreased without affecting pain control. As a result, the multiple possible detriments of having more narcotics available than actually necessary would be lessened. By limiting the overall number of narcotic tablets prescribed, decreased use by the patient when such a medication may no longer be appropriate, and minimized use by others in the household who might have access to it would decrease.

The body areas from where sutures are removed later, where wound healing is delayed. Epidural analgesia is the most effective method but could not be used for postoperative pain. Peripheral nerve blockers also provided excellent analgesia but are not effective in postoperative pain. Infiltration of the surgical wound with local anesthetics is decreased postoperative pain by inhibiting transmission of noxious impulses at the site. The objective of the study was to explore the effect of the local infiltration of the surgical wounds with low-dose of levobupivacaine, ibuprofen, and epinephrine over the sutured muscle wound in postoperative pain. Laparotomy was performed in adult rats under isoflurane anesthesia. During surgery, the surgical wounds were infiltrated with 50μL solution containing 0.3% w/v levobupivacaine, 2mg/mL ibuprofen, and 8mg/mL epinephrine (treatment group) and compared to infiltration of that of water for injection (vehicle group) over the sutured muscle wound before skin closing. Postoperative pain was assessed by rodent grimace scales scoring. The study also carried out for measurement for histopathological examinations and the tensile strength of wound. The one-way ANOVA following the Dunnett Multiple comparisons test was used to show significant differences between parameters at 95% level of confidence. The fall in pain started with three-hour post-surgery in the treatment group. At 24h after the end of the successful infiltration, the treatment group had significant reduction of a pain than vehicle group (p=0.048; q=3.527). After three weeks of the wound were closed, a significant improvement of angiogenesis process (p=0.021) and the tensile strength (p=0.019) for the treatment group as compared to baseline. The experimental study was reported that local infiltration of the surgical wound with levobupivacaine, ibuprofen, and epinephrine combination was effective in the postoperative pain and healing of the surgical wounds.

Transversus abdominis plane (TAP) blocks are increasingly being utilized in microvascular breast reconstruction. The implications of TAP blocks on specific reconstructive, patient and institutional outcomes remain to be fully elucidated. Patients undergoing abdominally-based microvascular breast reconstruction from 2015-2017 were reviewed. Length of stay, complications, narcotic consumption, donor-site pain and hospital expenses were compared between patients that did and those that did not receive TAP blocks with liposomal bupivacaine. Outcomes were subsequently compared in patients with elevated body mass index (BMI). Fifty patients (43.9%) received TAP blocks (27 [54.0%] under ultrasound guidance) and 64 patients (56.1%) did not. Patients with TAP blocks had significantly decreased oral and total narcotic consumption (p=0.0001 and p<0.0001, respectively) as well as significantly less donor-site pain (3.3 versus 4.3, p<0.0001). There was no significant difference in hospital expenses between the two cohorts ($21,531.53 versus $22,050.15 per patient, p=0.5659). Patients with BMI≥25 who received TAP blocks had a significantly decreased length of stay (3.8 versus 4.4 days, p=0.0345) as well as decreased narcotic consumption and postoperative pain compared to patients without TAP blocks. Patients with BMI<25 did not have a significant difference in postoperative pain, narcotic consumption or length of stay between the TAP versus no TAP block groups. TAP blocks with liposomal bupivacaine significantly reduce oral and total postoperative narcotic consumption as well as donor-site pain in all patients after abdominally-based microvascular breast reconstruction without increasing hospital expenses. TAP blocks additionally significantly decrease length of stay in patients with BMI≥25.

Povidone iodine is used primarily as an antiseptic to decrease surgical site infection. Its hemostatic and antiedematous properties in oral surgery also have been investigated recently. A randomized controlled clinical trial was performed in 30 patients undergoing mandibular third molar removal in a split-mouth design. In the study group, a povidone iodine solution with a concentration of 0.5 mg/mL was used as the coolant and irrigant solution, whereas normal saline was used in the control group. Swelling (orotragus and mentotragus distances), trismus (maximum interincisal opening), and pain (visual analog scale score) were evaluated on postoperative days 2 and 7. In the study group, a significant decrease in swelling and trismus was observed at the 2 postoperative visits (P = .00) compared with the control group. The decrease of pain in the study group was not statistically significant at either postoperative visit (P > .05). More patients (63%) were subjectively satisfied with the side treated with povidone iodine. Povidone iodine irrigation is an inexpensive and safe method to lessen the postoperative sequelae of third molar surgery. Copyright © 2015. Published by Elsevier Inc.

2017-12-01

Non-steroidal anti-inflammatory drugs have been shown to effectively decrease postoperative pain and reduce opioid requirements. Flurbiprofen axetil is an injectable non-selective cyclooxygenase inhibitor that has a high affinity for inflammatory tissues to achieve targeted drug therapy and prolonged duration of action. This meta-analysis examined the use of preoperative flurbiprofen axetil and its impact on postoperative analgesia. An electronic literature search of the Library of PubMed, Cochrane CENTRAL, and EMBASE databases was conducted in Feb 2016. Searches were limited to randomized controlled trials. The primary outcome was pain scores. The secondary outcomes included cumulative postoperative opioid consumption and opioid-related adverse effects. A total of nine RCT studies involving 457 patients were included in this study. Compared to patients without perioperative flurbiprofen axetil, patients treated with preoperative flurbiprofen axetil had lower pain scores at 2 h (SMD -1.00; 95% CI -1.57 to -0.43, P = 0.0006), 6 h (SMD -1.22; 95% CI -2.01 to -0.43; P = 0.002), 12 h (SMD -1.19; 95% CI -2.10 to -0.28; P = 0.01), and 24 h (SMD -0.79; 95% CI -1.31 to -0.27; P = 0.003) following surgery. Preoperative flurbiprofen axetil had no significant effect on postoperative opioid consumption (SMD -13.11; 95% CI -34.56 to 8.33; P = 0.23). There was no significant difference between the groups with regard to adverse effects. Compared to patients with postoperative flurbiprofen axetil, however, preoperative flurbiprofen axetil resulted in decreased pain score only at 2 h after operation. Preoperative use of flurbiprofen axetil will result in significantly lower postoperative pain scores, but no difference in nausea, vomiting, and opioid consumption compared to those who did not receive flurbiprofen axetil. However, more homogeneous and well-designed clinical studies are necessary to determine whether preoperative flurbiprofen axetil administration has more efficacy than that given at the end of surgery.

The harvest of iliac crest bone grafts (ICBG) is associated with relevant donor site pain, but may be lowered by the application of lidocaine loaded on biodegradable, hemostatic putty for sustained local analgesic release. The goal of this double-blind controlled trial was to assess the efficacy of adding lidocaine to a hemostatic putty (Orthostat ™) to treat donor site pain following harvest of ICBG in foot and ankle procedures. After ICBG harvest during a foot and ankle procedure, the resulting bone defect was either filled with Orthostat™ (n = 7) or with the same hemostatic putty loaded with lidocaine (Orthostat-L™, n = 7). During the first 72 postoperative hours, donor site and surgical site pain were managed by patient controlled morphine delivery and a peripheral nerve block. Donor site pain was periodically quantified on a Visual Analog (VAS) and a Wong Baker FACES scale. Pain scores were plotted over time to calculate the area under the curve (AUC) to quantify the overall pain experienced in specific time intervals. Orthostat-L™ significantly reduced donor site pain over the first 12 hours postoperatively as evidenced by a significant decrease of the AUC in both VAS (p = 0.0366) and Wong Baker FACES pain score plots (p = 0.0024). Cumulated morphine uses were not significantly decreased with Orthostat-L™. The addition of lidocaine to a hemostatic putty offers a significant ICBG donor site pain reduction over the first 12 postoperative hours. ClinicalTrials.gov NCT01504035.

Although laparoscopic colorectal surgery decreases postoperative pain and facilitates a speedier recovery compared with laparotomy, postoperative pain at trocar insertion sites remains a clinical concern. The objective of this study was to assess the effects of a preoperative ultrasound-guided transversus abdominis plane (TAP) block on pain after laparoscopic surgery for colorectal cancer. In total, 58 patients scheduled to undergo laparoscopic surgery following a diagnosis of colorectal cancer were included in this study. The patients were randomized into TAP and control groups; the TAP group patients received a preoperative ultrasound-guided bilateral TAP block with 0.5 mL/kg of 0.25 % bupivacaine, while the control patients received the block with an equal amount of saline. Pain on coughing and at rest was assessed during postanesthetic recovery (PAR; 1 h after surgery) and on postoperative days (PODs) 1 (24 h), 2 (48 h), and 3 (72 h) by an investigator blinded to group allocations using the numeric rating scale (NRS). The primary outcome was pain on coughing on postoperative day (POD) 1. Fifty-five patients were included in the final analysis, including 28 in the TAP and 27 in the control groups. The pain intensity on coughing and at rest during PAR and on PODs 1, 2, and 3 showed no significant differences between groups. Furthermore, there was no significant difference in postoperative opioid consumption, sedation scores, nausea scores at the four time points, complication rates, and length of hospital stay between groups. In colorectal cancer patients undergoing laparoscopic colorectal surgery, a TAP block did not offer enough benefit for clinical efficacy in terms of postoperative pain or analgesic consumption.

Preemptive Analgesia in Thumb Basal Joint Arthroplasty: Immediate Postoperative Pain with Preincision versus Postincision Local Anesthesia.

Purpose  Currently no guidelines exist for the timing of the injection of anesthetics in surgeries performed under general anesthesia to minimize postoperative pain. To better understand the role of timing of the injection of local anesthesia in hand surgery performed under general anesthesia, we evaluated the effect of pre- versus postincisional local analgesic injection on immediate postoperative pain experience. We hypothesize that the preincisional (preemptive) injection will result in decreased immediate postoperative pain experience and analgesic use when compared with postincisional injection. Methods  Consecutive cases of thumb basal joint arthroplasty performed over a 4-year period were retrospectively reviewed. During the first half of the study period, the surgical site was infiltrated with 0.5% bupivacaine at the completion of surgery following closure. During the second half of the study period, the surgical site was infiltrated with 0.5% bupivacaine prior to skin incision. Data collected included patient demographics, immediate postoperative recovery room (PACU) pain scores, and postoperative opioid consumption in morphine equivalents. Results  Two-tailed t -test identified no significant difference between the pre- and postincision cohorts relative to PACU entrance pain scores and time spent in the PACU. PACU exit pain scores were significantly lower in the preincision cohort. The mean PACU pain score was also significantly lower in the preincision cohort. PACU opioid consumption, converted into morphine equivalents, was found to be 211 mg in the preincision versus 299 mg in the postincision cohort. Conclusion  The preincisional (preemptive) injection of local anesthesia was found to result in lower pain scores during and upon exit of the PACU as compared with the postclosure group. In addition, the preincision cohort also trended toward lower opioid consumption while in the PACU. Consideration should be given to the routine use of preincision injection of local anesthesia to maximize pain relief in a multimodal pain strategy in hand surgical patients. Level of Evidence  Therapeutic level III.

Purpose: Postoperative radiotherapy decreases breast cancer mortality. However, studies have revealed a long-lasting breast pain among some women after radiotherapy. The purpose of this study was to identify risk factors that contribute to breast pain after breast cancer radiotherapy. Methods and Materials: We identified 1,027 recurrence-free women in two cohorts of Swedish women treated for breast cancer. The women had breast-conserving surgery and postoperative radiotherapy, the breast was treated to 48 Gy in 2.4-Gy fractions or to 50 Gy in 2.0-Gy fractions. Young women received a boost of up to 16 Gy. Women with more than three lymph node metastasesmore » had locoregional radiotherapy. Systemic treatments were given according to health-care guidelines. Three to 17 years after radiotherapy, we collected data using a study-specific questionnaire. We investigated the relation between breast pain and potential risk modifiers: age at treatment, time since treatment, chemotherapy, photon energy, fractionation size, boost, loco-regional radiotherapy, axillary surgery, overweight, and smoking. Results: Eight hundred seventy-seven women (85%) returned the questionnaires. Among women up to 39 years of age at treatment, 23.1% had breast pain, compared with 8.7% among women older than 60 years (RR 2.66; 95% CI 1.33-5.36). Higher age at treatment (RR 0.96; 95% CI 0.94-0.98, annual decrease) and longer time since treatment (RR 0.93; 95% CI 0.88-0.98, annual decrease) were related to a lower occurrence of breast pain. Chemotherapy increased the occurrence of breast pain (RR 1.72; 95% CI 1.19-2.47). In the multivariable model only age and time since treatment were statistically significantly related to the occurrence of breast pain. We found no statistically significant relation between breast pain and the other potential risk modifiers. Conclusions: Younger women having undergone breast-conserving surgery with postoperative radiotherapy report a higher occurrence of long-lasting breast pain compared to older women. Time since treatment may decrease the occurrence of pain.« less

ABSTRACT Purpose: To identify perioperative predictors of immediate pain after ureteroscopy, specifically evaluating the impact of hydrodistention from irrigation on pain. Materials and Methods: We retrospectively identified patients who underwent ureteroscopy for the treatment of calculi. Data recorded for these patients included their maximum pain score in the post-anesthesia care unit (PACU), average flow rate of irrigant used during the procedure, patient and stone characteristics, operative procedure, and details of patients' immediate, post-operative course. Spearman's rho was used to determine the relationship between non-parametric, continuous variables. Then, a linear regression was performed to assess which variables could predict the peak pain score. Results: A total of 131 patients were included in the study. A non-parametric correlation analysis revealed that maximum pain score was negatively correlated with being male (r = −0.18, p=0.04), age (r = −0.34, p<0.001), and post-op foley placement (r = −0.20, p=0.02) but positively correlated with the preoperative pain score (r = 0.41, p<0.001), time in the PACU (r = 0.19, p = 0.03), and the morphine equivalent dose (MED) of narcotics administered in the PACU (r = 0.67, p<0.001). On linear regression, the significant variables were age, preoperative pain score, and stent placement. For every ten-year increase in age post-operative pain score decreased by 4/10 of a point (p = 0.03). For every 1 point increase in preoperative pain score there was a 3/10 of a point increase in the maximum pain score (p = 0.01), and leaving a stent in place post-operatively was associated with a 1.6 point increase in the maximum pain score. Conclusions: Hydrodistention does not play a role in post-ureteroscopy pain. Patients who are younger, have higher preoperative pain scores, or who are stented will experience more post-operative pain after ureteroscopy. PMID:27564284

The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane) from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups) with no treatment (control group) or opioid administration (opioid group) where the outcomes of interest were postoperative pain intensity, rescue analgesic consumption, or adverse effects (sedation, nausea and vomiting, bad dream, worsening sleep pattern, and hallucination) 0-24 hours after leaving the operation room were included in the analysis. The pain score reported by the physician during first 4 hours and need for analgesics during 24 hours postoperatively was significantly decreased in the ketamine group versus control group and was similar with the opioid group. In addition, there was no significant difference between ketamine and control groups for adverse effects during 24 hours postoperatively. In the subgroup analyses (systemic and local administration) regarding pain related measurements, peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity and need for analgesics. Preoperative administration of ketamine systemically or locally could provide pain relief without side-effects in children undergoing tonsillectomy. However, considering the insufficient evaluation of efficacy of ketamine according to the administration methods and high heterogeneity in some parameters, further clinical trials with robust research methodology should be conducted to confirm the results of this study.

Arthroscopic anterior cruciate ligament (ACL) reconstruction is a painful procedure requiring intensive postoperative pain management. Femoral nerve block is widely used in ACL surgery. However, femoral nerve block does not cover the donor site of the hamstring tendons. Local infiltration analgesia is a simple technique that has proven effective in postoperative pain management after total knee arthroplasty. Further, local infiltration analgesia covers the donor site and is associated with few complications. It was hypothesised that local infiltration analgesia at the donor site and wounds would decrease pain and opioid consumption after ACL reconstruction with hamstring tendon graft. Sixty patients undergoing primary ACL surgery with hamstring tendon graft were randomised to receive either local infiltration analgesia or femoral nerve block. Pain was scored on the numeric rating scale, and use of opioid, range of motion and adverse effects were assessed at the postoperative recovery unit (0 h), 3, 24 and 48 h, postoperatively. There were no significant differences between the groups in pain intensity or total opioid consumption at any of the follow-up points. Further, there were no differences between groups concerning side effects and range of motion. Local infiltration analgesia and femoral nerve block are similar in the management of postoperative pain after ACL reconstruction with hamstring tendon graft. Until randomised studies have investigated femoral nerve block combined with infiltration at the donor site, we recommend local infiltration analgesia in ACL reconstruction with hamstring tendon graft.

Three hundred and twenty-two Canadian animal health technologists (AHTs) were surveyed to determine their attitudes toward postoperative pain management in dogs and cats following 6 surgical procedures, their concerns regarding the use of opioid analgesics, and their role within veterinary practices with respect to postoperative pain control. Two hundred and sixty-four (82%) returned the questionnaire. Pain perception was defined as the average of pain rankings for dogs and cats (on a scale of 1 to 10) following abdominal surgery, or the value for dogs or cats if the AHT worked with only 1 of the 2 species. Maximum concern about the risks associated with the postoperative use of morphine or oxymorphone was defined as the highest rating assigned to any of the 6 risks evaluated in either dogs or cats. Animal health technologists reported significantly higher pain perception scores than did veterinarians who completed a similar survey 2 years previously. Higher pain perception scores were associated with decreased satisfaction with the adequacy of analgesic therapy in their practice, higher pain control goals, and attendance at continuing education within the previous 12 months. The majority of AHTs (55%) agreed that one or more risks associated with the use of morphine or oxymorphone outweighed the benefits. The 3 issues that were perceived to pose the greatest risk were respiratory depression, bradycardia, and sedation and excitement, for dogs and cats, respectively. Most AHTs (68%) considered their knowledge related to the recognition and control of pain to be adequate, compared with 24% of veterinarians who responded to a similar previous survey. As for veterinarians, experience gained while in practice was ranked as the most important source of knowledge, while the technical program attended was ranked as least important. Over 88% of the AHTs provided nursing care during the postoperative period, monitored animals for side effects of postoperative analgesic therapy, informed veterinarians when animals were in pain, recommended analgesic therapy when they believed it was warranted, reported that animals received analgesics when they believed it was warranted, administered analgesics under the instruction of a veterinarian, and believed they were part of a team working to provide adequate postoperative pain control.

Our objective was to perform a pilot study comparing intracapsular radiofrequency ablation tonsillectomy with subcapsular tonsillectomy in adult patients with keratosis pharyngeous. Patients diagnosed with keratosis pharyngeous between December 2010 and February 2013 were randomized to undergo either intracapsular or subcapsular tonsillectomy using radiofrequency ablation. Postoperative pain scores and amount of pain medication taken were recorded for 2 weeks. A 6-month follow-up questionnaire was used to assess efficacy of the procedure. Twenty-two patients completed the initial 2-week questionnaire. Eighteen completed the 6-month follow-up questionnaire. The amount of pain medication consumed on postoperative days 8 (p = 0.0293), 9 (p = 0.0146), and 10 (p = 0.035) was significantly less in the intracapsular group. Risk of recurrence of tonsilloliths was significantly greater at the 6-month follow-up in the intracapsular cohort (p = 0.0291). Based on these findings, in patients undergoing tonsillectomy for keratosis pharyngeous, intracapsular radiofrequency ablation tonsillectomy may result in decreased pain medication consumption compared with subcapsular tonsillectomy. Intracapsular tonsillectomy, however, resulted in a higher rate of recurrence of tonsilloliths. The benefit of decreased pain medication may be offset by the greater likelihood for symptoms to recur. Larger studies are needed to confirm these findings.

Total hip and knee replacment surgeries are characterized by severe postoperative pain. Local infiltration analgesia is proved to be very effective. However this method has not been widely used in Hungary. To evaluate the efficacy of the local infiltration analgesia with modified components in patients underwent total hip or knee replacement surgery. Data of 99 consecutive patients underwent primary total hip or knee replacement surgery were evaluated prospectively. In all the 99 surgeries modified local infiltration analgesia was applied. Postoperative pain reported on a visual analog scale was recorded as well as the need for further analgetics during the first 18 hours after surgery. The cost of the analgetic drugs was calculated. The control group comprised 97 consecutive patients underwent total hip or knee replacement, where local infiltration analgesia was not applied. Statistical analysis was done. Patients received local infiltration analgesia reported significantly less pain (p<0.001). The need for postoperatively given analgetics was almost 50% less, and the cost of all postoperative analgetics was 47% less than in the control group. In total hip and knee replacement surgeries the modified local infiltration analgesia decreases postoperative pain effectively and contribute to the early mobilization of the patients. Orv.

During arthroscopy for the treatment of patellofemoral lateral hyper-pressure syndrome (LHS), intra-articular morphine or its derivatives (fentanyl) may reduce postoperative pain when combined with anesthetics. We therefore decided to determine whether adding fentanyl to epinephrine and bupivacaine produced an increased analgesia. We randomly distributed 40 patients into two groups. The experimental group (n=20) was given 0.5% bupivacaine (2 mg/kg), epinephrine (100 microg) and fentanyl (2.5 microg/kg). The control group (n=20) received 0.5% bupivacaine (2 mg/kg) and epinephrine (100 microg). Patients underwent chondroplasty and retinacular release, and we assessed pain, time of analgesia and postoperative range of motion at postoperative hours 6 and 24. The age and the grade of patellofemoral chondromalacia (PFC) were similar in both groups (p > 0.05). No differences were found in pain and ranges of motion intraoperatively and at postoperative hours 6 and 24 (p > 0.05) between both groups. The postoperative analgesia time was similar (p > 0.05). Adding intra-articular fentanyl to the combination of epinephrine plus bupivacaine did not decrease pain, and did not increase neither the analgesia time nor the range of motion in patients with LHS undergoing knee arthroscopy.

The purpose of this study was to determine if an intraoperative intraarticular and soft-tissue injection of local anaesthetic, epinephrine, and morphine has a beneficial effect for total knee arthroplasty. A control group of 138 patients (181 knees) received no intraoperative injection. The study group of 171 patients (197 knees) received intraoperative injection of 0.25% bupivacaine with epinephrine and morphine with 2/3 injected into the soft tissues and 1/3 injected into the joint. Patients having bilateral simultaneous procedures received a divided dose. The pain treatment protocol otherwise was identical. Pain, sedation, rescue narcotic usage, narcotic reversal and blood loss were examined. Pain levels during the immediate postoperative period, blood loss, and bleeding indices were reduced with injection. Considerably more control patients required rescue doses of narcotics. Preemptive analgesia with soft tissue and intra-articular injection of long-acting local anesthetic with epinephrine and morphine provides better pain control in the immediate postoperative period, decreases blood loss, and decreases the need for rescue narcotics and reversal agents. This simple, inexpensive method provides an effective adjunct to a multimodal approach in improving the postoperative course of primary total knee arthroplasty.

A single-dose adductor canal block can provide postoperative analgesia for patients undergoing total knee arthroplasty (TKA). The purpose of this study was to assess postoperative opioid consumption after ultrasound-guided single-injection bupivacaine compared with saline adductor canal block for patients undergoing TKA. After institutional review board approval, written informed consent was obtained from patients (>18 years old) undergoing elective TKA. Subjects were randomized into 2 groups as follows: adductor canal blockade with 10 mL of bupivacaine 0.25% with epinephrine 1:300,000 or 10 mL of normal saline. All patients received a periarticular infiltration mixture intraoperatively with scheduled and patient requested oral and IV analgesics postoperatively for breakthrough pain. Personnel blinded to group allocation recorded pain scores and opioid consumption every 6 hours. Pain burden, area under the numeric rating score for pain, was calculated for 36 hours. The primary outcome was postoperative IV/IM morphine (mg morEq) consumption at 36 hours after surgery. Forty (28 women/12 men) subjects were studied. Postoperative opioid consumption was reduced in the bupivacaine 48 (39 to 61) mg morEq compared with saline 60 (49 to 85) mg morEq, difference -12 (-33 to -2) mg morEq (P = 0.03). Pain burden at rest was decreased in the bupivacaine 71 (37 to 120) score · hours compared with saline 131 (92 to 161) score · hours, difference -60 (-93 to -14) score · hours (P = 0.009). Adductor canal blockade with bupivacaine 0.25% with epinephrine 1:300,000 effectively reduces pain and opioid requirement in the postoperative period after TKA. Adductor canal blockade is an effective pain management adjunct for patients undergoing TKA.

During microvascular breast reconstruction, exposure of internal mammary vessels (IMVs) is facilitated by the removal of a portion of the rib resulting in occasional chest contour deformity (CCD). The use of rib plating may reduce CCD and reduce postoperative pain. All patients underwent microvascular breast reconstruction using IMVs. In the retrospective arm, photographs were assessed by a blinded reviewer for CCDs. In the prospective cohort, patients were randomized to rib plating with the Synthes Matrix Rib Plating System or no rib plating. Postoperatively, patients were assessed for CCD and pain. In the retrospective arm, 11 of 98 (11.2%) patients representing 12 of 130 (9.2%) breast reconstructions had a noticeable contour deformity. The average body mass index (BMI) of patients with CCDs was 26.6 kg/m. In the prospective arm, there was 16% (3 of 19) rate of visible and palpable CCDs among controls, compared to 0% rate of palpable and visible contour deformity in the rib plating group. Pain was decreased in the rib plating group on all postoperative days. The pain reduction was statistically significant at rest by postoperative day 30. The majority of patients (9 of 11) with compromised aesthetic outcomes had a BMI less than 30 kg/m, suggesting a paucity of overlying soft tissue contributed to visibility of these bony defects. Rib plating prevented chest contour deformity, reduced postoperative pain, and added limited additional morbidity. We believe that rib plating is a safe, useful adjunct to microvascular breast reconstruction using IMVs, as it may improve aesthetic outcomes and reduce postoperative pain.

Background The number of total hip replacement surgeries has steadily increased over recent years. Reduction in postoperative pain increases patient satisfaction and enables better mobilization. Thus, pain management needs to be continuously improved. Problems are often caused not only by medical issues but also by organization and hospital structure. The present study shows how the quality of pain management can be increased by implementing a standardized pain concept and simple, consistent, benchmarking. Methods All patients included in the study had undergone total hip arthroplasty (THA). Outcome parameters were analyzed 24 hours after surgery by means of the questionnaires from the German-wide project “Quality Improvement in Postoperative Pain Management” (QUIPS). A pain nurse interviewed patients and continuously assessed outcome quality parameters. A multidisciplinary team of anesthetists, orthopedic surgeons, and nurses implemented a regular procedure of data analysis and internal benchmarking. The health care team was informed of any results, and suggested improvements. Every staff member involved in pain management participated in educational lessons, and a special pain nurse was trained in each ward. Results From 2014 to 2015, 367 patients were included. The mean maximal pain score 24 hours after surgery was 4.0 (±3.0) on an 11-point numeric rating scale, and patient satisfaction was 9.0 (±1.2). Over time, the maximum pain score decreased (mean 3.0, ±2.0), whereas patient satisfaction significantly increased (mean 9.8, ±0.4; p<0.05). Among 49 anonymized hospitals, our clinic stayed on first rank in terms of lowest maximum pain and patient satisfaction over the period. Conclusion Results were already acceptable at the beginning of benchmarking a standardized pain management concept. But regular benchmarking, implementation of feedback mechanisms, and staff education made the pain management concept even more successful. Multidisciplinary teamwork and flexibility in adapting processes seem to be highly important for successful pain management. PMID:28031727

Interscalene block (ISB) can provide pain relief after shoulder surgery, but a reliable quantification of its analgesic benefits is lacking. This meta-analysis examines the effect of single-shot ISB on analgesic outcomes during the first 48 hours after shoulder surgery. We retrieved randomized and quasirandomized controlled trials examining the analgesic benefits of ISB compared with none in shoulder surgery. Severity of postoperative pain measured on a visual analog scale (10 cm scale, 0 = no pain, 10 = worst pain) at rest at 24 hours was the designated primary outcome. Secondary outcomes included pain severity at rest and with motion at 2, 4, 6, 8, 12, 16, 32, 36, 40, and 48 hours postoperatively. Opioid consumption, postoperative nausea and vomiting, patient satisfaction with pain relief, and postanesthesia care unit and hospital discharge time were also assessed. A total of 23 randomized controlled trials, including 1090 patients, were analyzed. Patients in the ISB group had more severe postoperative pain at rest by a weighed mean difference (95% confidence interval) of 0.96 cm (0.08-1.83; P = 0.03) at 24 hours compared with no ISB, but there was no difference in pain severity beyond that point. The duration of pain relief at rest and with motion after ISB were 8 and 6 hours, respectively, with a corresponding weighed mean difference in visual analog scale pain scores (99% confidence interval) of -1.59 cm (-2.60 to -0.58) and -2.20 cm (-4.34 to -0.06), respectively, with no additional pain relief benefits beyond these points. ISB reduced postoperative opioid consumption up to 12 hours, decreased postoperative nausea and vomiting at 24 hours, and expedited postanesthesia care unit and hospital discharge. The type, dose, and volume of local anesthetic used did not affect the results. ISB can provide effective analgesia up to 6 hours with motion and 8 hours at rest after shoulder surgery, with no demonstrable benefits thereafter. Patients who receive an ISB can suffer rebound pain at 24 hours but later experience similar pain severity compared with those who do not receive an ISB. ISB can also provide an opioid-sparing effect and reduce opioid-related side effects in the first 12 and 24 hours postoperatively, respectively. These findings are useful to inform preoperative risk-benefit discussions regarding ISB for shoulder surgery.

The Effect of Preoperative Ketorolac on WBC Response and Pain in Laparoscopic Surgery for Endometriosis

PubMed Central

2005-01-01

Surgical stress causes changes in the composition of white blood cells (WBCs). Ketorolac is believed to have analgesic effects and to reduce the stress response and may therefore improve postoperative outcomes. The aim of this study was to assess the effect of preoperative ketorolac on the WBC subsets in patients who had laparoscopic surgery for endometriosis. Fifty patients who had laparoscopic surgery for endometriosis were randomly assigned to one of two groups: the ketorolac group (n = 25) received ketorolac 0.5 mg/kg before the induction of anesthesia, and the control group (n = 25) received saline. White cell count, differential, and pathology studies were done immediately after surgery, on postoperative day 1, and on postoperative day 3. We compared the baseline values within and between the two groups. We also assessed postoperative pain and side effects. The time that elapsed before the first patient request for analgesia, total meperidine dose and VAS (Visual Analog Scale) for postoperative pain were significantly lower in the ketorolac group than in the control group. Compared to the pre- surgical values, there was an increase in total WBC count and percentage of neutrophils, but a decrease in percentages of lymphocytes, monocytes, eosinophils, basophils, and leucocytes. Total WBC count, neutrophils, monocytes, eosinophils and leucocytes showed significant differences between the two groups. The incidences of postoperative side effects, such as nausea, dizziness, headache, and shoulder pain were not different between the groups. Preoperative ketorolac reduced postoperative pain and influenced the WBC response in laparoscopic surgery for endometriosis. PMID:16385658

To assess the effect of platelet-rich fibrin (PRF) on postoperative pain, swelling, trismus, periodontal healing on the distal aspect of the second molar, and progress of bone regeneration in mandibular third molar extraction sockets. Over a 2-year period, 31 patients (mean age, 26.1 yr) who required surgical extraction of a single impacted third molar and met the inclusion criteria were recruited. After surgical extraction of the third molar, only primary closure was performed in the control group, whereas PRF was placed in the socket followed by primary closure in the case group (16 patients). The outcome variables were pain, swelling, maximum mouth opening, periodontal pocket depth, and bone formation, with a follow-up period of 3 months. Quantitative data are presented as mean. Statistical significance was inferred at a P value less than .05. Pain (P = .017), swelling (P = .022), and interincisal distance (P = .040) were less in the case group compared with the control group on the first postoperative day. Periodontal pocket depth decreased at 3 months postoperatively in the case (P < .001) and control (P = .014) groups, and this decrease was statistically significant. Bone density scores at 3 months postoperatively were higher in the case group than in the control group, but this difference was not statistically important. The application of PRF lessens the severity of immediate postoperative sequelae, decreases preoperative pocket depth, and hastens bone formation.

Activation of signal transducer and activator of transcription-3 (STAT3) is suggested to be critically involved in the development of chronic pain, but the complex regulation of STAT3-dependent pathway and the functional significance of inhibiting this pathway during the development of neuropathic pain remain elusive. To evaluate the contribution of the JAK2/STAT3 pathway to neuropathic pain and the potentiality of this pathway as a novel therapeutic target, we examined the effects of the STAT3 inhibitor WP1066 by intrathecal administration in a rat model of bilateral chronic constriction injury (bCCI). The pain behavior tests were performed before the surgery and on postoperative day 3, 7, 14 and 21. L4-L6 dorsal spinal cord were harvested at each time point. Both RT-PCR and Western blot were performed to evaluate the activation of JAK2/STAT3 pathway. To observe the influence of WP1066 on neuropathic pain and its molecular mechanism, WP1066 (10 μl, 10 mmol/L in DMSO) or the same capacity of DMSO as the control were applied through the intrathecal tube on the day before bCCI surgery, and on the postoperative day 3 and 5. Behavioral tests were performed to observe the therapeutic effect on mechanical, thermal and cold hyperalgesia. L4-L6 dorsal spinal cord was harvested on postoperative day fourteen, followed by RT-PCR and Western blot evaluation of the JAK2/STAT3 pathway activation. The mechanical, thermal and cold hyperalgesia of the bCCI rats were significantly decreased when compared with the Sham or the Naïve group at each postoperative time point (P<0.05). JAK2 mRNA and STAT3 mRNA were significantly increased in the bCCI rats, accompanied by SOCS3 mRNA with a similar tendency. Western blot analysis showed that JAK2 and phosphorylated STAT3 increased significantly since 3 days after bCCI. JAK2 peaked on postoperative day 14 while phosphorylated STAT3 peaked on postoperative day 7 and gradually decreased thereafter and SOCS3׳s peak level on postoperative day 3. When WP1066 were administered intrathecally, the pain behaviors of the bCCI rats were significantly improved (P<0.05). WP1066 also inhibited the mRNA level of JAK2, STAT3 and SOCS3 in bCCI rats significantly, together with the protein level of JAK2, phosphorylated STAT3 and SOCS3 on postoperative day 14 as well. Our results found that the JAK2/STAT3 pathway in the spinal cord dorsal horn was significantly activated in the bCCI neuropathic pain rats. WP1066, which inhibited the STAT3 pathway specifically, could partially alleviate the pain behavior of the bCCI rats. So it may serve as a novel therapeutic strategy against neuropathic pain.

Background and objectives The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. Subjects and Methods Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane) from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups) with no treatment (control group) or opioid administration (opioid group) where the outcomes of interest were postoperative pain intensity, rescue analgesic consumption, or adverse effects (sedation, nausea and vomiting, bad dream, worsening sleep pattern, and hallucination) 0–24 hours after leaving the operation room were included in the analysis. Results The pain score reported by the physician during first 4 hours and need for analgesics during 24 hours postoperatively was significantly decreased in the ketamine group versus control group and was similar with the opioid group. In addition, there was no significant difference between ketamine and control groups for adverse effects during 24 hours postoperatively. In the subgroup analyses (systemic and local administration) regarding pain related measurements, peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity and need for analgesics. Conclusion Preoperative administration of ketamine systemically or locally could provide pain relief without side-effects in children undergoing tonsillectomy. However, considering the insufficient evaluation of efficacy of ketamine according to the administration methods and high heterogeneity in some parameters, further clinical trials with robust research methodology should be conducted to confirm the results of this study.

Chandna, Shalu; Kedige, Suresh Dyamappa

2015-01-01

Background: Gingival depigmentation is a periodontal plastic surgical procedure whereby the gingival hyperpigmentation is removed by various techniques such as electrosurgery, cryosurgery, abrasion with diamond bur and lasers. The aim of this study was to determine the pain levels during the gingival depigmentation procedure using electrosurgery and lasers. Materials and Methods: Twenty patients, both male and female, between the ages of 20 and 40 years were randomly allocated into two groups of 10 patients each: Those undergoing depigmentation with electrosurgery (Group I) and those by diode lasers (Group II). Patients of both groups were asked to define the level of pain and discomfort by using the Visual Analog Scale (VAS) intraoperatively, 24 h post-operatively and 1 week post-operatively. Results: Both the groups showed a decrease in the pain levels, which was statistically highly significant 1 week post-operatively when compared 24 h post-operatively. There was a statistically highly significant difference in the pain levels between the electrosurgery and the lasers groups after 24 h (P < 0.001), with the lasers group demonstrating lesser pain and discomfort. Although there was no significant difference between the two groups intraoperatively and 1 week post-operatively on comparison, lesser mean scores were observed for the lasers group. Conclusion: The growing concern for esthetic requires the removal of hyperpigmentated gingival areas to create a confident and pleasant smile, which could be easily attained by using either electrosurgery or lasers. This study concluded that lasers produce lesser pain and discomfort compared with electrosurgery during gingival depigmentation. PMID:25810593

The purpose of this clinical study was to determine the effect of 1- or 2-visit root canal treatment on the postoperative pain in the retreatment cases. Two hundred eighteen cases that required retreatment were included in the study. Obturated and unfilled canal space and the status of periapical tissues were evaluated according to the PAI index. The patients were subcategorized in regard to the presence or the absence of preoperative pain. Approximately half of each category was treated in 1 appointment. After removing the previous root canal obturation materials and biomechanic preparation of root canals, the teeth in the 1-visit group were obturated at the first appointment by using AH 26 sealer and laterally compacted gutta-percha, and those in the 2-visit group were medicated with calcium hydroxide-chlorhexidine combination and then closed with a temporary filling material. One week after the initial appointment, patients were asked about the occurrence of postoperative pain. The level of discomfort was rated as no pain, mild pain, moderate pain, or severe pain (flare-up). Data were statistically analyzed using the chi-squared and Fischer exact tests. Eight patients from the 1-visit group and 2 patients from the 2-visit group had flare-ups. There was a statistical difference between the groups (P <.05). Two-visit root canal treatment was more effective in completely eliminating pain than 1-visit treatment of previously symptomatic teeth (P <.05). Two-visit endodontic treatment with intracanal medication was found to be effective in reducing postoperative pain of previously symptomatic teeth and decreased the number of flare-ups in all retreatment cases.

Local infiltration anesthesia with steroids in total knee arthroplasty: A systematic review of randomized control trials.

Tran, Jonathan; Schwarzkopf, Ran

2015-10-01

Local infiltration anesthesia (LIA) with anesthetics, steroids, NSAIDS, and epinephrine has been shown to be effective in reducing total knee arthroplasty (TKA) postoperative pain. This systematic review explores the functional outcomes of randomized control trials that have compared the use of LIA with and without steroids during TKA. Five studies with 412 patients met the inclusion criteria, 228 received local infiltration anesthesia with steroids (LIAS) and 184 received local infiltration anesthesia without steroids (LIAWS). The use of LIAS in management of postoperative TKA pain has been shown to decrease the length of hospital stay, time required to achieve straight leg raise, and pro-inflammatory signals in patients. Although there is no overwhelming data to suggest LIAS improves postoperative TKA pain, current literature does support its effectiveness in producing other favorable surgical outcomes.

The purpose of this pilot study was to explore the use of massage therapy in children with cerebral palsy undergoing post-operative rehabilitation. Three participants were randomized to massage therapy and another three participants to rest. All children had undergone surgery in one or two lower limbs. Pain, wellbeing, sleep quality, heart rate and qualitative data were collected for each child. The scores of pain intensity and discomfort were low in all participants. Heart rate decreased in participants who were randomized to rest, but no change was found in the massage therapy group. The lack of decrease in heart rate in the study group of massage therapy may imply an increased sensitivity to touch in the post-operative setting. Further research with larger study populations are needed to evaluate how and when massage therapy is useful for children with cerebral palsy. Copyright © 2010 Elsevier Ltd. All rights reserved.

Shoulder surgery can produce severe postoperative pain and movement limitations. Evidence has shown that regional nerve block is an effective management for postoperative shoulder pain. The purpose of this study was to investigate the postoperative analgesic effect of intravenous patient-controlled analgesia (PCA) combined with interscalene nerve block in comparison to PCA alone after shoulder surgery. In this study, 103 patients receiving PCA combined with interscalene nerve block (PCAIB) and 48 patients receiving PCA alone after shoulder surgery were included. Patients' characteristics, preoperative shoulder score and range of motion, surgical and anesthetic condition in addition to visual analog scale (VAS) pain score, postoperative PCA consumption, and adverse outcomes were evaluated. The results showed that PCA combined with interscalene nerve block (PCAIB) group required less volume of analgesics than PCA alone group in 24 hours (57.76 ± 23.29 mL versus 87.29 ± 33.73 mL, p < 0.001) and 48 hours (114.86 ± 40.97 mL versus 183.63 ± 44.83 mL, p < 0.001) postoperatively. The incidence of dizziness in PCAIB group was significantly lower than PCA group (resp., 1.9% and 14.6%, p = 0.005). VAS, nausea, and vomiting were less in group PCAIB, but in the absence of significant statistical correlation. Interscalene nerve block is effective postoperatively in reducing the demand for PCA analgesics and decreasing opioids-induced adverse events following shoulder surgery.

Nasal packing is an option for bleeding control after endoscopic sinus surgery and septoplasty. Although new packing materials have been developed, patients still suffer from pain and require additional analgesics treatments. In this study, a prospective, randomized, and double-blind controlled trial was designed to evaluate the effect of fentanyl-soaked packing on pain after endoscopic sinus surgery and septoplasty. One hundred fifty-two patients who underwent nasal surgeries due to chronic rhinosinusitis or nasal septal deviation were enrolled in this study. At the end of operation, 50 mcg fentanyl-soaked biodegradable synthetic polyurethane foams packing Nasopore or Merocel were applied to a group of 79 patients, and saline-soaked ones were applied to another group of 73 patients. To evaluate the influence of fentanyl on postoperative nasal pain, patients' conditions were assessed via means of Numeric Rating Scale, patient satisfaction, and Ramsay Sedation Scale. In addition, symptoms of headache or sore throat and any signs of cardiopulmonary-relevant indicators were monitored. The fentanyl group had significantly decreased Numeric Rating Scale and increased patient satisfaction in every operation type for the majority of postoperative time periods ( P < .05) with reduced postoperative headache and sore throat compared to the control group. The fentanyl group showed a higher score on Ramsay Sedation Scale than the control group ( P < .05 in group including endoscopic sinus surgery). There were no significant differences in cardiopulmonary-relevant indicators between the 2 groups ( P > .05). Fentanyl group showed significantly reduced postoperative pain without serious adverse effects. We suggest that topical fentanyl application to nasal packs can be a useful method to reduce pain during the early postoperative period after endoscopic sinus surgery and septoplasty.

To determine whether premedication with 45 mg of oral dextromethorphan (DM) given 90 minutes prior to nasal surgery decreases postoperative pain and consequently reduces opioid administration and also, if it reduces the pain of pack removal. This was a prospective, double blind, randomized, controlled study carried out from January 2007 to March 2008 at Al-Moosa General Hospital, Al-Ahsa, Saudi Arabia, in which 38 patients received oral DM (age 28 +/- 11 years), and 38 patients received placebos (age 26 +/- 10 years). Postoperative pain was assessed using a visual analog scale, and a pain score of > or -5 was treated by a rescue bolus dose of morphine sulfate 2 mg every 10 minutes in the post-anesthesia care unit (PACU) and by one gm of paracetamol in the surgical ward until the score became <5. Pain was also assessed during pack removal. The placebo group had a higher pain score in the PACU, and hence a higher morphine consumption than the DM group (7.3 mg +/- 2.6 versus 4.6 mg +/- 1.2, p=0.03). Pain score in the surgical ward was also higher in the placebo group at 4, 8, 12, and 24 hours, but this was insignificant, and was insignificantly lower only at 18 hours (p=0.26). The placebo group had a higher pain score at pack removal than the DM group (7.8 +/- 11 versus 3.5 +/- 15, p=0.004). Preemptive medication with DM reduces opioid administration in the early postoperative period and during pack removal.

Introduction Epidural analgesia provides an important synergistic method of pain control. In addition to reducing perioperative opioid consumption, the deliverance of analgesia into the epidural space, effectively creating a sympathetic blockade, has a multitude of additional potential benefits, from decreasing the incidence of postoperative delirium to reducing the development of persistent postsurgical pain (PPSP). Prior studies have also identified a correlation between the use of epidural analgesia and improved oncological outcomes and survival. The aim of this study is to evaluate the effect of epidural analgesia in pancreatic operations on immediate postoperative outcomes, the development of PPSP and oncological outcomes in a prospective, single-blind, randomised controlled trial. Methods The Epidurals in Pancreatic Resection Outcomes (E-PRO) study is a prospective, single-centre, randomised controlled trial. 150 patients undergoing either pancreaticoduodenectomy or distal pancreatectomy will be randomised to receive an epidural bupivacaine infusion following anaesthetic induction followed by continued epidural bupivacaine infusion postoperatively in addition to the institutional standardised pain regimen of hydromorphone patient-controlled analgesia (PCA), acetaminophen and ketorolac (intervention group) or no epidural infusion and only the standardised postoperative pain regimen (control group). The primary outcome was the postoperative opioid consumption, measured in morphine or morphine-equivalents. Secondary outcomes include patient-reported postoperative pain numerical rating scores, trend and relative ratios of serum inflammatory markers (interleukin (IL)-1β, IL-6, tumour necrosis factor-α, IL-10), occurrence of postoperative delirium, development of PPSP as determined by quantitative sensory testing, and disease-free and overall survival. Ethics and dissemination The E-PRO trial has been approved by the institutional review board. Recruitment began in May 2016 and will continue until the end of May 2018. Dissemination plans include presentations at scientific conferences and scientific publications. Trial registration number NCT02681796. PMID:29374667

Acute remifentanil exposure during intraoperative analgesia might enhance sensitivity to noxious stimuli and nociceptive responses to innocuous irritation. Cyclooxygenase inhibition was demonstrated to attenuate experimental remifentanil-induced hyperalgesia (RIH) in rodents and human volunteers. The study aimed to compare the effects of preoperative and postoperative flurbiprofen axetil (FA) on RIH after surgery. Ninety patients undergoing elective laparoscopic gynecologic surgery were randomly assigned to receive either intravenous placebo before anesthesia induction (Group C); or intravenous FA (1.0 mg/kg) before anesthesia induction (Group F1) or before skin closure (Group F2). Anesthesia consisted off sevoflurane and remifentanil (0.30 μg/kg/min). Postoperative pain was managed by sufentanil titration in the postanesthetic care unit, followed by sufentanil infusion via patient-controlled analgesia. Mechanical pain threshold (primary outcome), pain scores, sufentanil consumption, and side-effects were documented for 24 hours postoperatively. Postoperative pain score in Group F1 was lower than Group C. Time of first postoperative sufentanil titration was prolonged in Group F1 than Group C (P=0.021). Cumulative sufentanil consumption in Group F1 was lower than Group C (P<0.001), with a mean difference of 8.75 (95% confidence interval, 5.21-12.29) μg. Mechanical pain threshold on the dominant inner forearm was more elevated in Group F1 than Group C (P=0.005), with a mean difference of 17.7 (95% confidence interval, 5.4-30.0) g. Normalized hyperalgesia area was decreased in Group F1 compared to Group C (P=0.007). No statistically significant difference was observed between Group F2 and Group C. Preoperative FA reduces postoperative RIH in patients undergoing laparoscopic gynecologic surgery under sevoflurane-remifentanil anesthesia.

Standardization of postoperative care has been shown to decrease postoperative length of stay. In June 2009, we standardized postoperative care for all gastrectomies at our institution. Four years' worth of total gastrectomies (2 years prior to standardization and 2 years after standardization) were reviewed to determine the effect of standardization on postoperative care, length of stay, complications, and readmissions. Between June 2007 and July 2011, 99 patients underwent curative intent open total gastrectomy: 51 patients prior to standardization, and 48 patients poststandardization. Patients were predominantly male (70%); median age was 63; and median body mass index was 26. Standardization of postoperative care was associated with a decrease in median time to beginning both clear liquids and a postgastrectomy diet, earlier removal of epidural catheters, earlier use of oral pain medication, less time receiving intravenous fluids, and decreased length of stay (all P < .01). Groups showed no differences in complication rates, complication severity, diet intolerance, return to our Urgent Care Center, or readmission. Institution of standardized postoperative orders for total gastrectomy was associated with a significantly decreased length of stay and earlier oral feeding without increasing postoperative complications, early postoperative outpatient visits, or readmissions.

To assess the efficacy and safety of circumferential cremasteric lysis in the treatment of adult symptomatic retractile testicles. This is a retrospective chart review of all patients who had undergone circumferential cremasteric lysis at a single institution performed by a single surgeon between January 2010 and December 2011. We evaluated the etiology, pre- and postoperative pain intensity, postoperative pain alleviation, and any surgical complications. We used the Wilcoxon signed-rank test to compare pain levels before and at last follow-up after surgery. Eight patients (mean age, 31.5 ± 10.60; range, 22-51 years) underwent circumferential cremasteric lysis. The procedure resulted in a clinically meaningful and statistically significant difference in postoperative pain intensity. The mean pain levels decreased from 5.6 (preoperatively) to 1.5 (at last follow-up) (5.6 vs 1.5, P < .01, Wilcoxon signed-rank test). The mean follow-up was 21.63 ± 13.70 months (range, 9-50 months). Four patients (50%) reported complete resolution and four (50%) reported partial resolution of their testicular pain at last follow-up. In this limited retrospective study, we demonstrated that circumferential lysis of the cremasteric muscle through a small subinguinal incision is a safe and effective minimally invasive procedure for physical activity-precipitated painful retractile testicular pain.

Demonstration of improved postoperative pain management by implementation of the S3 guidelines on treatment of acute perioperative and posttraumatic pain, by the integrated quality management concept "quality management acute pain" of the TÜV Rheinland or by participation in the benchmark project "Quality improvement in postoperative pain management" (QUIPS). A prospective controlled study (pre-post design) was carried out in hospitals with various levels of care comparing three hospital groups (n = 17/7/3, respectively). Group 1: participation in the QUIPS project (intraclinic and interclinic comparison of outcome data of postoperative pain treatment), group 2: participation in the quality management acute pain program (certified by TÜV Rheinland), group 3: control group with no involvement in either of the two concepts. In all three groups, an anonymous data collection was performed consisting of patient-reported pain intensity, side effects, pain disability and patient satisfaction. Pain therapy intervention was carried out only in group 2 by an integrated quality management concept (certification project: Quality management acute pain) with a package of measures to improve structure, process and outcome quality. The TÜV Rheinland certified clinics (group 2) showed a significant improvement in the pre-post comparison (before versus after certification) in the areas maximum pain (from visual analogue scale VAS 4.6 to 3.7), stress pain (5.3 to 3.9), pain-related impairment (proportion of patients with pain-linked decreased mobility and movement 26% to 16.1%, coughing and breathing 23.1% to 14.3%) and patient satisfaction (from 13.2 to 13.7; scale 0 completely unsatisfied, 15 very satisfied). The clinics with participation in QUIPS for 2 years also showed a significant improvement in stress pain (numeric rating scale NRS for pain 4.5 to 4.2), pain-linked-limitation of coughing and breathing (28% to 23.6%), and patient satisfaction (from 11.9 to 12.4). There were no differences in postoperative nausea and vomiting between any of the groups. The main objective of the certification concept quality management acute pain as a tool for the successful implementation of the S3 guidelines on treatment of acute perioperative and posttraumatic pain, led to a significant improvement in patient outcome. Participation in QUIPS is an ideal supplement to TÜV Rheinland certification and can be recommended as a benchmarking tool to evaluate outcome.

The pain after thyroid surgery is considered of moderate intensity and short duration. Most trials showed significant reduction in pain intensity and severity of pain in patients for whom bilateral superficial cervical plexus block (BSCPB) was done. To assess the postoperative analgesic effect of BSCPB for thyroid surgery. Sixty six euthyroid patients were recruited and assigned to two groups (33 patients each). Group 1 BSCPB and Group 2 standard analgesia. The unpaired Student's t -test and Mann-Whitney test were used for comparison. Statistical significance was stated at p value < 0.05. The median postoperative pain score (NRS) was 3 in the BSCPB group and 5 in the control group ( p =0.002). There was also statistically significant difference at 6th, 12th, and 24th hour showing a lower median pain score in the BSCPB group compared to the control group. The median time was (360 minutes) in the treatment group and (180 minutes) in the control group ( p =0.0006). The median tramadol consumption within 24 hours is 0 mg in the BSCPB group compared to 100 mg in the control group ( p =0.001). BSCPB done for thyroidectomy under general anesthesia decreases the postoperative pain score, total analgesia consumption, and time to first analgesia request.

Background Alpha-2 adrenergic agonists produce safe and effective analgesia, but most investigations studying the analgesic effect of alpha-2 adrenoceptor agonists postoperatively included previous or concomitant administration of other analgesics. Because clonidine potentiates the effect of these drugs, its own intrinsic analgesic effect has been difficult to establish. This study was designed to compare the intraoperative and postoperative effects of epidural clonidine vs bupivacaine for patients undergoing lower abdominal surgery. Methods This randomized controlled trial included 40 patients aged 18-50 who were scheduled for elective lower abdominal surgery. Patients were randomly divided into 2 groups. Group I (n=20) received epidural clonidine; Group II (n=20) received epidural bupivacaine. Intraoperative and postoperative hemodynamics, pain scores, and complications were monitored. Results Mean pain scores were significantly lower in Group I compared to Group II (1.5 ± 0.5 compared to 3.4 ± 1.0, respectively) in the first 12 hours after surgery. Sedation was more prominent in Group I until 9 hours after surgery. Opioid requirements were significantly lower in Group I. Respiratory rate was similar in the 2 groups. Group I had larger decreases from baseline in systolic blood pressure and diastolic blood pressure than Group II. Heart rate in Group I was reduced from baseline, while it was increased in Group II. Less postoperative nausea and vomiting, urinary retention, pruritus, and shivering were observed in Group I. Conclusion Compared to bupivacaine, epidural clonidine provided effective intraoperative and postoperative analgesia in selected patients, resulting in a decreased intravenous pain medication requirement and prolonged duration of analgesia after epidural infusion was discontinued.

To measure and compare postoperative pain and patient satisfaction in patients undergoing either robotic or open laparotomy for surgical staging of endometrial cancer. Prospective, comparative study (Canadian Task Force classification II). University hospital. A total of 142 patients undergoing either robotic or open laparotomy for surgical staging of endometrial cancer. Patients scheduled for surgical staging of endometrial cancer at a single institution were identified. The patients underwent either robotic or open hysterectomy for staging of endometrial cancer. The choice of operative approach (robotic vs laparotomy) was made by the faculty physician before enrollment. Patients participated in the study for up to 48 hours for pain assessments and up to 10 ± 3 days postoperatively for quality of recovery assessments. The following measurements were performed: postoperative pain with the visual analog scale (VAS), 24-hour opioid consumption, and quality of recovery using the Quality of Recovery Questionnaire (QoR-40). The study was terminated owing to futility, given the lack of open procedures at our institution. Despite that lack of statistically significant difference between VAS scores at rest and with leg extension, there was a significant decrease in 24-hour opioid consumption in the robotic group. In addition, the QoR-40 showed an increased perception of recovery in patients within the robotic group compared with the laparotomy group. Patients with endometrial cancer who underwent robotic surgery had decreased postoperative opioid consumption and improved quality of recovery compared with those who underwent surgery via laparotomy.

Breast reduction is one of the most frequently performed plastic surgical procedures in the United States; more than 160,500 patients underwent the procedure in 2005. Many outpatient reduction mammaplasty patients report the greatest postoperative discomfort in the first 48 hours. The authors' investigated the effect of intraoperative topical application of the long-acting local anesthetic agent bupivacaine (Sensorcaine or Marcaine) on postoperative pain, time to postanesthesia care unit discharge, and postoperative use of narcotic medication. In a prospective, randomized, single-blind trial, intraoperative use of Sensorcaine versus placebo (normal saline) was compared. Postoperative pain was quantified using the visual analogue scale, and time to discharge from the postanesthesia care unit was recorded. Patients documented their outpatient pain medication usage. Of the 37 patients enrolled in the study, 20 were treated with intraoperative topical Sensorcaine and 17 received placebo. Patients treated with Sensorcaine were discharged home significantly faster (2.9 hours versus 3.8 hours, p = 0.002). The control arm consistently had higher pain scores in the postanesthesia care unit (although not statistically significant) than the Sensorcaine group using the visual analogue scale system. Furthermore, patients receiving Sensorcaine required significantly less narcotic medication while recovering at home (mean, 3.5 tablets of Vicodin) than the control group (mean, 6.4 tablets; p = 0.001). There were no complications resulting from Sensorcaine usage. This prospective, randomized, single-blind study demonstrates that a single dose of intraoperative Sensorcaine provides a safe, inexpensive, and efficacious way to significantly shorten the length of postanesthesia care unit stay and significantly decrease postoperative opioid analgesic use in patients undergoing ambulatory reduction mammaplasty.

Comparative analgesic efficacy of different doses of dexamethasone during infraumbilical surgery: A Randomized controlled trial

Background: Postoperative pain is a common complaint and despite the availability of various drugs, is still not managed well. Analgesic effects of glucocorticoids are still to be substantially established. Hence, we designed randomized, double-blind, placebo-controlled trial to compare the effect of two different doses of dexamethasone on postoperative pain in patients undergoing infra-umbilical surgeries under spinal anesthesia. Methods: Ninety American Society of Anesthesiologists Grade I and II patients were randomized to receive injection dexamethasone 8 mg (Group DI), dexamethasone 16 mg (Group DII) or placebo (Group C) prior to performance of intrathecal block. Outcome studied was postoperative pain on the rest and motion and nausea and vomiting. Result: There was no difference in Visual Analog Scale (VAS) scores during rest in all the three groups. However, VAS scores on motion showed a significant decrease in Group DII at 24 and 36 h when compared to Group C (95% confidence interval [CI] of mean at 24 h for Group C = 5.6093–7.1049 and Group DII = 4.8709–5.9567, P = 0.04; 95% CI of mean at 36 h for Group C = 4.5868–5.8418 and Group DII = 3.5388–4.7378, P = 0.01). There was no significant difference in the incidence of postoperative nausea and vomiting or additional analgesic requirements. Conclusion: Dexamethasone 16 mg reduces postoperative pain on motion at 24 and 36 h. It has no effect on postoperative pain at rest or on nausea and vomiting. PMID:25886418

Cardiovascular effects of bupivacaine and the role of this agent in preemptive dental analgesia.

Inappropriately high blood concentrations of bupivacaine have been reported to cause toxicity and even death. The potential for cardiovascular toxicity and the difficulty with which this may be reversed has made the dental practitioners reluctant to use this agent. Nevertheless, cardiovascular toxicity from its use in and around the mouth is exceedingly rare. This study was undertaken to assess bupivacaine's cardiotoxic potential in the practice of oral and maxillofacial surgery. Results showed a dose-dependent decrease in systolic blood pressure, but no other statistically significant cardiovascular change was noted. Preemptive treatment of postsurgical pain has been the subject of numerous trials. Bupivacaine administered preoperatively has been suggested to prevent central nervous system "conditioning," thus decreasing the perceived postoperative pain. However, there was no statistical support for any reduction in the perceived postoperative pain in the treatment groups in this study.

Ketamine is often added to opioids in patient-controlled analgesia devices. We tested whether in surgical patients, ketamine added to an opioid patient-controlled analgesia decreased pain intensity by ≥25%, cumulative opioid consumption by ≥30%, the risk of postoperative nausea and vomiting by ≥30%, the risk of respiratory adverse effects by ≥50%, and increased the risk of hallucination not more than 2-fold. In addition, we searched for evidence of dose-responsiveness. Nineteen randomized trials (1349 adults, 104 children) testing different ketamine regimens added to various opioids were identified through searches in databases and bibliographies (to 04.2016). In 9 trials (595 patients), pain intensity at rest at 24 hours was decreased by 32% with ketamine (weighted mean difference -1.1 cm on the 0-10 cm visual analog scale [98% CI, -1.8 to -0.39], P < 0.001). In 7 trials (495 patients), cumulative 24 hours morphine consumption was decreased by 28% with ketamine (weighted mean difference -12.9 mg [-22.4 to -3.35], P = 0.002). In 7 trials (435 patients), the incidence of postoperative nausea and vomiting was decreased by 44% with ketamine (risk ratio 0.56 [0.40 to 0.78], P < 0.001). There was no evidence of a difference in the incidence of respiratory adverse events (9 trials, 871 patients; risk ratio 0.31 [0.06 to 1.51], P = 0.08) or hallucination (7 trials, 690 patients; odds ratio 1.16 [0.47 to 2.79], P = 0.70). Trial sequential analyses confirmed the significant benefit of ketamine on pain intensity, cumulative morphine consumption, and postoperative nausea and vomiting and its inability to double the risk of hallucination. The available data did not allow us to make a conclusion on respiratory adverse events or to establish dose-responsiveness.

2015-01-01

Minor adverse effects related to anesthesia are common and worrisome to patients, including perioperative vomiting, gagging on the endotracheal tube, incisional pain, and nausea. A previously published intravenous anesthesia protocol reports extremely low rates of postoperative nausea and vomiting (<1%) and decreases in postoperative pain perception compared with rates reported following administration of inhalational anesthetics. To evaluate and compare postoperative outcomes in patients after administration of combined propofol and ketamine hydrochloride anesthesia with bispectral index monitoring (PKA-BIS protocol) vs inhalational anesthesia (IA) during lower rhytidoplasty. We performed a prospective, double-blind, randomized comparison trial of the PKA-BIS protocol and IA in 30 consecutive female patients undergoing rhytidoplasty by a single surgeon at a single outpatient surgery center from October 2013 to June 2014. Outcome measures included nausea, vomiting, pain, overall feeling of well-being, time to awaken, time to discharge, and cost. Patient measures were recorded using a combination of a 40-item validated postoperative quality of recovery questionnaire (QOR-40) and visual analog scales (VASs). Results were recorded immediately after surgery and on postoperative days 1 and 7. A statistically significant reduction in emergence time (mean [SD], 29.8 [10.6] vs 46.0 [10.2] minutes; P < .001) and time to meet discharge criteria (51.4 [19.3] vs 66.1 [12.9] minutes; P = .02) was seen in patients in the PKA-BIS group. Patient-reported (subjective) postoperative nausea (3 of 15 [20%] vs 7 of 15 patients [47%]; P = .12; χ2 = 2.40), vomiting (0 vs 2 of 15 patients [13%]; P = .14; χ2 = 2.14), and confusion on the day of surgery (3 of 15 [20%] vs 6 of 14 patients [43%]; P = .18; χ2 = 1.77) were also decreased in the PKA-BIS group, but these differences did not reach significance. Differences in global recovery scores (QOR-40 scores in the postanesthesia care unit, 158.13 [22.68] vs 155.33 [18.09]; P = .71; at day 1, 166.47 [26.39] vs 166.00 [16.00]; P = .96), postoperative overall feeling of well-being (VAS scores at day 1, 6.10 vs 6.26; at day 7, 7.49 vs 8.00), and postoperative pain perception (VAS scores at day 1, 3.40 vs 3.65; at day 7, 2.26 vs 1.81) between the PKA-BIS and IA groups, respectively, did not reach significance. The costs of anesthesia administration were similar between the PKA-BIS ($10.37/h) and IA ($8.47/h to $9.87/h) groups. The PKA-BIS protocol for anesthesia appears to be a comparable alternative to traditional IA in patients undergoing elective rhytidoplasty. A larger patient sample size is needed to determine whether trends toward decreased nausea, vomiting, and postoperative confusion and differences in postoperative pain perception are significant. clinicaltrials.gov Identifier: NCT02410460. 1.

Local anesthetics decrease postoperative pain when placed at the surgical site. Patients benefit from laparoscopic extraperitoneal hernia repair because this allows earlier mobilization than the more classical open surgical approach. The purpose of this study was to determine the pain-sparing efficacy of local anesthetics placed in the preperitoneal fascial plane during extraperitoneal laparoscopic inguinal hernia surgery. Forty-two outpatients were included in a double-blind, randomized, placebo-controlled, institutional review board-approved study. At the conclusion of a standardized general anesthetic, 21 patients received 60 mL of 0.125% bupivacaine into the preperitoneal fascial plane before incisional closure, whereas the other 21 patients received 60 mL of the isotonic sodium chloride solution placebo. Postoperative pain was assessed 1, 4, 8, 24, and 72 h postoperatively. In addition, postoperative fentanyl and outpatient acetaminophen 500 mg/hydrocodone 5 mg requirements were recorded. All hernia repairs were performed by the same surgeon. Appropriate statistical analyses were used. There were no significant differences between the bupivacaine and isotonic sodium chloride solution groups with regard to postoperative pain scores, length of postanesthesia care unit stay, or analgesic requirements. Furthermore, neither unilateral versus bilateral repair nor operative time affected the measured parameters. The addition of 60 mL of 0.125% bupivacaine into the preperitoneal fascial plane during extraperitoneal laparoscopic hernia repair did not significantly alter pain scores, supplementary analgesic requirements, or recovery room length of stay. The placement of 60 mL of 0.125% bupivacaine into the preperitoneal fascial plane during extraperitoneal laparoscopic hernia repair did not significantly alter pain scores, supplementary analgesic requirements, or recovery room length of stay.

Local Infiltration of Analgesics at Surgical Wound to Reduce Postoperative Pain After Laparotomy in Rats.

There is an increasing use of local infiltration analgesia (LIA) to reduce postoperative pain. Despite widespread use of LIA, wide variations in drug combinations and concomitant use of systemic analgesics have made it difficult to determine the optimal drug combinations for LIA. Using a previously validated rat laparotomy model, the optimal LIA combination of medications to reduce postoperative pain was determined. Laparotomy was performed in an adult rat model under isoflurane anesthesia. During surgery, combinations of bupivacaine, ketorolac, and dexamethasone were injected over the sutured muscle wound before skin closing, and compared to saline (placebo). The same medications were injected systemically as controls. Postoperative pain was assessed by measuring spontaneous rearing activity. A high-dose 3-drug LIA combination (50 μL of bupivacaine 0.75%, ketorolac 6.0 mg/mL, and dexamethasone 2.0 mg/mL) increased rearing (decreased pain) at 2 hours (P = 0.0032) postsurgery compared to saline. However, the same 3 drugs injected systemically had a similar analgesic effect (P = 0.0002). Bupivacaine 0.75% alone was not effective for LIA. When low-dose (9-fold reduction) 3-drug LIA combination was used, LIA increased rearing (P = 0.0034) whereas the same 3 drugs injected systemically had no effect. Low-dose LIA ketorolac/dexamethasone (2-drug combination) also increased rearing (P = 0.0393). Our animal study suggests that clinical trials with low-dose LIA combinations of local anesthetic, nonsteroidal anti-inflammatory drug, and corticosteroid may be useful for reducing postoperative pain after laparotomy.

Background Preemptive analgesia may be considered as a method not only to alleviate postoperative pain but also to decrease analgesic consumption. Different regimens are suggested, but there is currently no standard. Objectives The aim was to measure the efficacy of preemptive analgesia with pregabalin, acetaminophen, naproxen, and dextromethorphan in radical neck dissection surgery for reducing the intensity of pain and morphine consumption. Patients and Methods This study was conducted as a randomized double-blind clinical trial. Eighty adult patients (18 to 60 years of age) under the American society of anesthesiologists (ASA) physical status I and II undergoing elective radical neck dissection were enrolled. Patients were randomized into two groups of 40 with a simple randomization method. The case group received a combination of 15 mg/kg acetaminophen, 2.5 mg/kg pregabalin, 7 mg/kg naproxen, and 0.3 mg/kg dextromethorphan administered orally one hour prior to surgery. Postoperative pain was assessed with the universal pain assessment tool (UPAT) at 0, 2, 4, 6, 12, and 24 hours after surgery. Subjects received morphine based on postoperative pain control protocol. Total administered morphine doses were noted. Results Postoperative pain rates at 0, 2, 4, 6, 12, and 24 hours after surgery were significantly lower for the case group than the control group (P values = 0.014, 0.003, 0.00, 0.00, and 0.00, respectively). Total morphine doses for the preemptive analgesia group were 45% lower than those of the other group. Side effects were similar for both groups. Conclusions A single preoperative oral dose of pregabalin, acetaminophen, dextromethorphan, and naproxen one hour before surgery is an effective method for reducing postoperative pain and morphine consumption in patients undergoing radical neck dissection.

Doppler guidance in hemorrhoidal surgery has become more frequent during the past decade. The method is mainly studied in nonrandomized trials. Data from randomized controlled trials are lacking. The aim of this study was to compare early and midterm results of transanal hemorrhoidal dearterialization with anopexy to open hemorrhoidectomy. DESIGN, SETTINGS, PATIENTS, AND INTERVENTIONS: Forty patients with grade 2 to 3 hemorrhoids were randomly assigned to transanal hemorrhoidal dearterialization with anopexy (group A, n = 20) or open hemorrhoidectomy (group B, n = 20). A diary was used during the first 2 postoperative weeks. A self-reported symptom questionnaire was answered, and a clinical examination was performed preoperatively, after 2 to 4 months, and after 1 year. The main outcome measure was postoperative pain. Postoperative peak pain was lower in group A during the first week than in group B (p < 0.05), whereas no difference in overall pain was noted. More patients expressed normal well-being in group A (p = 0.045). Pain, bleeding, and the need for manual reduction of the hemorrhoids were all improved in both groups after 1 year (p < 0.05). Soiling had decreased after both methods at early follow-up. After 1 year, soiling was significantly decreased only after open hemorrhoidectomy. The grade of hemorrhoids was significantly reduced after 1 year for both methods, but there was a trend to more patients with remaining grade 2 hemorrhoids in group A (p = 0.06). There was no blinding, the sample size was small, and follow-up was for only 1 year. The questionnaire was not validated. The difference in postoperative pain between transanal hemorrhoidal dearterialization with anopexy and open hemorrhoidectomy may be less than expected based on previous literature.

The purpose of this study was to compare postoperative pain and neuropathy after primary caesarean sections with either blunt or sharp fascial expansions. A total of 123 women undergoing primary caesarean sections were included in the study. The sharp group had 61 patients, and the blunt group had 62. In the sharp group, the fascia was incised sharply and extended using scissors. In blunt group, the fascia was bluntly opened by lateral finger-pulling. The primary outcome was postoperative pain. The long-term chronic pain scores were significantly lower in the blunt group during mobilisation (p = .012 and p = .022). Neuropathy was significantly more prevalent in the sharp group at both 1 and 3 months postoperatively (p = .043 and p = .016, respectively). The odds ratio (OR) and 95%CI for postoperative neuropathy at 1 and 3 months were as follows; OR 3.71, 95%CI 0.97-14.24 and OR 5.67, 95%CI 1.18-27.08, respectively. The OR for postoperative pain after 3 months was 3.26 (95%CI 1.09-9.73). The prevelance of postsurgical neuropathy and chronic pain at 3 months were significantly lower in the blunt group. Blunt fascial opening reduces the complication rate of postoperative pain and neuropathy after caesarean sections. Impact statement What is already known on this subject? The anatomic relationship of the abdominal fascia and the anterior abdominal wall nerves is a known fact. The fascia during caesarean sections can be opened by either a sharp or blunt extension. Data on the isolated impact of different fascial incisions on postoperative pain is limited. What do the results of this study add? The postoperative pain scores on the incision area are lower in the bluntly opened group compared to the sharp fascial incision group. By extending the fascia bluntly, a decrease in trauma and damage to nerves was observed. What are the implications of these findings for clinical practice and/or future research? The lateral extension of the fascia during caesarean sections must be done cautiously to prevent temporary damage to nerves and vessels. The blunt opening of the fascia by lateral finger pulling might be a preferred method over the sharp approach that uses scissors. We included only primary caesarean cases, however, comparisons of blunt and sharp fascial incisions in patients with more than one abdominal surgery should be explored in future studies.

The adequacy of postoperative analgesia was assessed in 40 cats following ovariohysterectomy. At extubation, cats were given one dose of carprofen, ketoprofen, meloxicam or tolfenamic acid. Postoperative analgesia was assessed using visual analogue scale (VAS) scoring for pain and sedation; measurement of mechanical nociceptive thresholds at the wound; recognition of the requirement for rescue intervention analgesia; and an overall clinical assessment score at 18 hours. VAS pain scores were low throughout the trial, with no significant differences found between the groups. Postoperative mechanical nociceptive thresholds decreased significantly from baseline in all four groups, with no significant differences between the groups. One cat in each of the tolfenamic acid, ketoprofen and meloxicam groups required rescue intervention analgesia. Nine out of 10 cats in all four groups were classified as having desirable overall clinical assessment scores. In summary, all four drugs provided good postoperative analgesia, although none was able to prevent postoperative wound tenderness.

A retrospective analysis. To evaluate the association between early postoperative dural sac cross-sectional area (DCSA) and radicular pain. The correlation between postoperative magnetic resonance imaging (MRI) findings and postoperative neurological symptoms after lumbar decompression surgery is controversial. This study included 115 patients who underwent lumbar decompression surgery followed by MRI within 7 days postoperatively. There were 46 patients with early postoperative radicular pain, regardless of whether the pain was mild or similar to that before surgery. The intervertebral level with the smallest DCSA was identified on MRI and compared preoperatively and postoperatively. Risk factors for postoperative radicular pain were determined using univariate and multivariate analyses. Subanalysis according to absence/presence of a residual suction drain also was performed. Multivariate regression analysis showed that smaller postoperative DCSA was significantly associated with early postoperative radicular pain (per -10 mm; odds ratio, 1.26). The best cutoff value for radicular pain was early postoperative DCSA of 67.7 mm. Even with a cutoff value of <70 mm, sensitivity and specificity are 74.3% and 75.0%, respectively. Early postoperative DCSA was significantly larger before suction drain removal than after (119.7±10.1 vs. 93.9±5.4 mm). Smaller DCSA in the early postoperative period was associated with radicular pain after lumbar decompression surgery. The best cutoff value for postoperative radicular pain was 67.7 mm. Absence of a suction drain at the time of early postoperative MRI was related to smaller DCSA.

Chronic pain is common and undesirable after surgery. Progression from acute to chronic pain involves altered pain processing. The authors studied relationships between presence of chronic pain versus preoperative descending pain control (diffuse noxious inhibitory controls; DNICs) and postoperative persistence and spread of skin and deep tissue hyperalgesia (change in electric/pressure pain tolerance thresholds; ePTT/pPTT) up to 6 months postoperatively. In 20 patients undergoing elective major abdominal surgery under standardized anesthesia, we determined ePTT/pPTT (close to [abdomen] and distant from [leg] incision), eDNIC/pDNIC (change in ePTT/pPTT with cold pressor pain task; only preoperatively), and a 100 mm long pain visual analogue scale (VAS) (0 mm = no pain, 100 mm = worst pain imaginable), both at rest and on movement preoperatively, and 1 day and 1, 3, and 6 months postoperatively. Patients reporting chronic pain 6 months postoperatively had more abdominal and leg skin hyperalgesia over the postoperative period. More inhibitory preoperative eDNIC was associated with less late postoperative pain, without affecting skin hyperalgesia. More inhibitory pDNIC was linked to less postoperative leg deep tissue hyperalgesia, without affecting pain VAS. This pilot study for the first time links chronic pain after surgery, poorer preoperative inhibitory pain modulation (DNIC), and greater postoperative degree, persistence, and spread of hyperalgesia. If confirmed, these results support the potential clinical utility of perioperative pain processing testing.

Patients undergoing renal transplant (RT) have altered drug/opioid pharmacokinetics. Transversus abdominis plane (TAP) block in renal transplant recipients has been recently evaluated for analgesic and opioid-sparing potential by many trials. The studies comparing TAP-block to conventional analgesic regimens for RT were searched. Comparisons were made for total opioids consumed (as morphine-equivalents) during the first postoperative 24-h (primary objective), intraoperative, and immediate-postoperative period. Pain scores and postoperative nausea-vomiting (PONV) were also evaluated. Trial sequential analysis (TSA) was used to quantify the strength of analysis. Ten-trials with 258 and 237 patients in control and TAP-block group, respectively, were included. TAP-block decreased the 24-h (reported in 9-trials) opioid consumption by 14.61 ± 4.34 mg (reduction by 42.7%, random-effects, P < 0.001, I 2 = 97.82%). Sample size of the present analysis (472) was well past the required "information-size" variable (396) as per the TSA for a power of 85%. Intraoperative opioid consumption also decreased by 2.06 ± 0.63 mg (reduction of 27.8%) (random effects, P < 0.001, I 2 = 98.84%). Pain scores with TAP-block were significantly lower in both early and delayed postoperative phase. Odds ratio for PONV without TAP block was 1.99 ± 1.05 (Fixed-effects, P = 0.04, I 2 = 0%). Publication bias was likely (Egger's test, X-intercept=7.89, P < 0.05). TAP-block significantly lowers the intraoperative and cumulative postoperative 24-h opioid consumption in RT recipients. Persistent and better pain control is achieved when TAP-Block is used. Benefits of TAP block extend beyond the analgesic actions alone as it also decreases the 24-h incidence of postoperative nausea vomiting as well. The technique of the block needs standardization for RT recipients.

The surgical treatment of hallux valgus deformity is connected with significant postoperative pain. Spinal and general anesthesia as well as peripheral blocks are successfully used in foot surgery. The purpose of this study was to evaluate the influence of local anesthetic infiltration before hallux valgus one-day surgery on postoperative pain and the need for analgesics. 134 patients underwent chevron or miniinvasive Mitchell-Kramer osteotomy of the first distal metatarsal. After general anesthesia each patient randomly received an infiltration of 7ml of local anesthetic (4 ml of 0.25% bupivacaine and 3 ml of 2% lidocaine) or the same amount of normal saline 15 minutes before the skin incision. Both the patient and the surgeon were blinded. The patient was discharged after approximately 2 hours of observation. 2, 4, 8, 12, 16, 24 and 72 hours after the release of the tourniquet the level of pain was assessed by the visual analogue scale (VAS). Rescue analgesia, side effects and the use of painkillers were noted. Preemptive local anesthetic infiltration significantly decreased pain during the first 24 hours after the surgery. None of the patients from the injected group and 38 from the placebo group received 100 mg of ketoprofen intravenously for rescue analgesia in the first 2 hours after the release of the tourniquet. During the first 24 hours we noted significantly decreased use of 1000 mg of paracetamol and 100 mg mg of ketoprofen orally in the injected group. No systemic adverse effects were noted. One patient from placebo group had allergic rush after use of 100 mg ketoprofen. Preemptive local anesthetic infiltration in one-day hallux valgus surgery significantly decreases postoperative pain. It is safe, efficient and allows fast discharge.

Although hydrocodone-acetaminophen is commonly used for pain control in first-trimester abortion, the efficacy of oral opioids for decreasing pain has not been established. Our objective was to estimate the effect of hydrocodone-acetaminophen on patient pain perception during first-trimester surgical abortion. We conducted a randomized, double-blinded, placebo-controlled trial. Patients (before 11 weeks of gestation) received standard premedication (ibuprofen and lorazepam) and a paracervical block with the addition of 10 mg hydrocodone and 650 mg acetaminophen or placebo 45-90 minutes before surgical abortion. A sample size of 120 was calculated to provide 80% power to show a 15-mm difference (α=0.05) in the primary outcome of pain with uterine aspiration (100-mm visual analog scale). Secondary outcomes were pain at additional time points, satisfaction, side effects, adverse events, and need for additional pain medications. There were no significant differences in demographics or baseline pain between groups. There were no differences in pain scores between patients receiving hydrocodone-acetaminophen compared with placebo during uterine aspiration (65.7 mm compared with 63.2 mm, P=.59) or other procedural time points. There were no differences in satisfaction or need for additional pain medications. Patients who received hydrocodone-acetaminophen had more postoperative nausea than those receiving placebo (P=.03) when controlling for baseline nausea. No medication-related adverse events were noted. Hydrocodone-acetaminophen does not decrease pain during first-trimester abortion and may increase postoperative nausea.

The minimally invasive transpsoas interbody fusion technique requires dissection through the psoas muscle, which contains the nerves of the lumbosacral plexus posteriorly and genitofemoral nerve anteriorly. Retraction of the psoas is becoming recognized as a cause of transient postoperative thigh pain, numbness, paresthesias, and weakness. However, few reports have described the nature of thigh symptoms after this procedure. The authors performed a review of patients who underwent the transpsoas technique for lumbar spondylotic disease, disc degeneration, and spondylolisthesis treated at a single academic medical center. A review of patient charts, including the use of detailed patient-driven pain diagrams performed at equal preoperative and follow-up intervals, investigated the survival of postoperative thigh pain, numbness, paresthesias, and weakness of the iliopsoas and quadriceps muscles in the follow-up period on the ipsilateral side of the surgical approach. Over a 3.2-year period, 59 patients underwent transpsoas interbody fusion surgery. Of these, 62.7% had thigh symptoms postoperatively. New thigh symptoms at first follow-up visit included the following: burning, aching, stabbing, or other pain (39.0%); numbness (42.4%); paresthesias (11.9%); and weakness (23.7%). At 3 months postoperatively, these percentages decreased to 15.5%, 24.1%, 5.6%, and 11.3%, respectively. Within the patient sample, 44% underwent a 1-level, 41% a 2-level, and 15% a 3-level transpsoas operation. While not statistically significant, thigh pain, numbness, and weakness were most prevalent after L4-5 transpsoas interbody fusion at the first postoperative follow-up. The number of lumbar levels that were surgically treated had no clear association with thigh symptoms but did correlate directly with surgical time, intraoperative blood loss, and length of hospital stay. Transpsoas interbody fusion is associated with high rates of immediate postoperative thigh symptoms. While larger, prospective studies are necessary to validate these findings, the authors found that half of the patients had symptom resolution at approximately 3 months postoperatively and more than 90% by 1 year.

Liposuction is a common cosmetic surgical procedure, which requires analgesia for postoperative pain. Transcutaneous electrical nerve stimulation (TENS) has been used for postoperative pain relief; however, there is no evidence of its effectiveness in liposuction patients and this is the focus of this paper. A prospective, randomized, double-blind, controlled trial was conducted with 42 adult patients who underwent liposuction. Patients were randomly allocated to either the TENS group (active TENS) or control group (sham TENS). All patients received morphine (0.1 mg/kg) and dipyrone 1 g immediately after surgery; TENS was delivered 2 h later. The primary outcome was pain intensity. Secondary outcomes were analgesic requirement, number and types of adverse effects of TENS, quality of pain, treatment success, and patient satisfaction. Postoperative pain was measured using a visual analog scale (VAS) and the Brazilian version of the McGill Pain Questionnaire (Br-MPQ). Patients in the TENS group reported significantly lower pain intensity (P < 0.001, effect size = 0.92) compared with those in the control group. TENS significantly decreased the consumption of analgesics in the postoperative period (P < 0.001). No withdrawals or adverse effects were observed in the TENS group, but 33.3% of patients in the control group reported drowsiness and nausea. About 95 and 38% of patients in the TENS and control groups, respectively, were satisfied with the analgesic treatment. The results indicate that TENS is effective as an adjunct to analgesics for pain relief after liposuction. This journal requires that authors assign a level of evidence to each article.

Recent studies suggest that preemptive analgesia may be effective in reducing postoperative pain. One physiologic explanation may be interference with the endogenous opioid response. We investigated whether long-lasting preoperative preemptive analgesia may have an effect on the hormonal stress response after total hip replacement. 42 patients scheduled for elective hip replacement for coxarthrosis were randomized to receive, on the day before the operation, either 5 ml*h(-1) ropivacaine 0.2% (study group, n = 21) or 5 ml*h(-1) saline (control group, n = 21). Postoperative analgesia was achieved in both groups by patient-controlled epidural analgesia (PCEA) with ropivacaine 0.2%. The main outcome measure was the concentration of authentic beta-endorphin [1-31] in plasma up to 4 days after surgery. Additional parameters included concentrations of adrenocorticotrope hormone and cortisol. Both groups were comparable concerning preoperative parameters and pain scores. Epidural blocks were sufficient in all patients for operative analgesia. Preemptive analgesia was performed for 11-20 hours in both groups and led to significantly decreased pain scores before surgery. Preemptive analgesia with epidural ropivacaine did not lead to decreased concentrations of beta-endorphin [1-31] before the start of surgery or in the postoperative period. Furthermore, no differences could be detected in the time course of beta-endorphin and adrenocorticotrope hormone after surgery. However, cortisol concentrations differed significantly between groups before the operation, but showed a comparable rise after surgery. Differences in postoperative pain after preemptive analgesia do not seem to be due to an altered endogenous opioid response.

To evaluate pain incidence and intensity in patients undergoing septorhinoplasty, and to assess analgesic treatment effectiveness, in the first 7 days after surgery. Prospective outcomes analysis using visual analogue scale assessment of pain intensity in the first 7 post-operative days. Fifty-seven patients were enrolled in the study, 29 women and 28 men, aged 18 to 51 years. All were treated for post-traumatic deformity of the external nose and/or nasal septum, with either septorhinoplasty or septoplasty. In the first 3 days after septorhinoplasty, patients' mean visual analogue scale pain score exceeded the range denoting 'analgesic success', and showed considerable exacerbation in the evening. Patients' pain decreased to a mean score of 15.4 one hour after administration of a nonsteroidal anti-inflammatory drug (metamizole). Analgesia is recommended for all patients in the first 3 days after septorhinoplasty, especially in the early evening.

To explore postoperative pain management experiences among school-aged children. Ineffective postoperative pain management among children has been commonly reported. School-aged children are able to evaluate how their pain is managed and what their preferred strategies are. Most studies in pain management have adopted quantitative methods and have overlooked children's pain management experiences. This is a qualitative study using face-to-face interviews. Data were collected from 15 school-aged children admitted to a tertiary hospital in Singapore by in-depth interviews conducted between November 2010 and January 2011. Data were analysed by thematic analysis. Five themes were identified: children's self-directed actions to relieve their postoperative pain (e.g. using cognitive-behavioural methods of distraction and imagery, physical method of positioning, sleeping and drinking, seeking other people's help by informing parents and crying and using pain medications); children's perceptions of actions parents take for their postoperative pain relief (assessing pain, administering pain medications, using various cognitive-behavioural, physical methods and emotional support strategies, assisting in activities and alerting health professionals); children's perception of actions nurses take for their postoperative pain relief (administering medication, using cognitive-behavioural methods, emotional support strategies and helping with activities of daily living) and suggestions for parents (using distraction and presence) and nurses (administering medications, distraction and positioning) for their postoperative pain relief improvement. This study contributed to the existing knowledge about children's postoperative pain management based on their own experiences. Children, their parents and nurses used various strategies, including pain medication and non-pharmacological methods, especially distraction, for children's postoperative pain relief. This study provides evidence for health care professionals to consider using more pain relief strategies when caring for children postoperatively and provide guidance for children to practice these strategies. © 2013 Blackwell Publishing Ltd.

A retrospective study of postoperative pain management with intrathecal morphine. Identify the dosing regimen of intrathecal morphine that safely and effectively provides postoperative analgesia with minimal complications in patients with idiopathic scoliosis undergoing posterior spinal fusion (PSF) and segmental spinal instrumentation (SSI). Postoperative pain after surgery for idiopathic scoliosis is a concern. Intrathecal morphine has been used to decrease pain. However, the most appropriate dose has not been determined. We retrospectively analyzed 407 consecutive patients with idiopathic scoliosis who underwent PSF and SSI at our institution from 1992 through 2006. Patients were divided into 3 groups based on the intrathecal morphine dose: no dose (n = 68); moderate dose of 9 to 19 microg/kg, mean 14 microg/kg (n = 293); and high dose of 20 microg/kg or greater, mean 24 microg/kg (n = 46). Data included demographics, Wong-Baker visual analog scale postoperative pain scores, postoperative intravenous morphine requirements, time to first rescue dose of intravenous morphine, and postoperative complications of pruritus, nausea/vomiting, respiratory depression, and pediatric intensive care unit (PICU) admission. The demographics of the 3 study groups showed no statistical differences. The mean Wong-Baker visual analog scale pain score in the post anesthesia care unit was 5.2, 0.5, and 0.2, and the mean time to first morphine rescue was 6.6, 16.7, and 22.9 hours, respectively. In the first 48 postoperative hours, respiratory depression occurred in 1 (1.5%), 8 (2.7%), and 7 (15.2%) patients, whereas PICU admission occurred in 0 (0%), 6 (2%), and 8 (17.4%) patients, respectively. The majority of PICU admissions were the result of respiratory depression. Frequency of pruritus and nausea/vomiting was similar in all 3 groups. Intrathecal morphine in the moderate dose range of 9 to 19 microg/kg (mean 14 microg/kg), provides safe and effective postoperative analgesia in the immediate postoperative period for patients with idiopathic scoliosis undergoing PSF and SSI. Higher doses did not result in significantly better analgesia and had a greater frequency of respiratory depression requiring PICU admission.

The aim of this study was the comparision of postoperative outcomes in impacted mandibular third molars that were treated using either platelet-rich fibrin (PRF), a combination of PRF and piezosurgery, or conventional rotatory osteotomy. The study included 20 patients; 40 extractions of impacted mandibular third molars were performed. Patients were divided into two main groups. In group A (n = 20), traditional surgery was performed on one side (Group 1, n = 10); traditional surgery was performed, and PRF was administered to the extracted socket on the other side of same patient (Group 2, n = 10). In group B (n = 20), on one side, piezosurgery was used for osteotomy, and PRF was administered (Group 3, n = 10); on the other side of same patient, traditional surgery was performed (Group 4, n = 10). Parameters assessed at baseline for each patient included pain, the number of analgesics taken, trismus, and cheek swelling. These variables were also assessed on postoperative days 1, 2, 3, and 7. Statistical analysis revealed a significant reduction in postoperative pain (sum of 1(st), 2(nd), 3(rd) and 7(th) days) and trismus (on postoperative day 1) in group 2 (traditional surgery + PRF group), and in postoperative pain, the number of analgesics taken (sum of 1(st), 2(nd),3(rd) and 7(th) days) and trismus (on postoperative day 1) in group 3 (piezosurgery + PRF group) compared to groups 1 and 4 (traditional surgery groups), (p ≤ 0.05). However, swelling on postoperative days 1, 3, and 7 did not differ among the groups (p > 0.05). Only difference was on second day between groups 1-4 and 2-4 (p ≤ 0.05). The results of our study have shown that the use of PRF with traditional surgery and PRF combined with piezosurgery significantly reduced pain during the postoperative period. In addition, PRF in combination with piezosurgery significantly decreased the number of analgesics taken. Both operations also significantly decreased trismus 24 h after the surgery. As a result of this study, PRF and combination use of PRF and piezosurgery have positive effects in reducing postoperative outcomes after impacted third molar surgery.

In the context of translational research, there is growing interest in studying surgical orthopedic pain management approaches that are common to humans and dogs. The validity of postoperative pain assessment methods is uncertain with regards to responsiveness and the potential interference of analgesia. The hypothesis was that video analysis (as a reference), electrodermal activity, and two subjective pain scales (VAS and 4A-VET) would detect different levels of pain intensity in dogs after a standardized trochleoplasty procedure. In this prospective, blinded, randomized study, postoperative pain was assessed in 25 healthy dogs during a 48-hour time frame (T). Pain was managed with placebo (Group 1, n = 10), preemptive and multimodal analgesia (Group 2, n = 5), or preemptive analgesia consisting in oral tramadol (Group 3, n = 10). Changes over time among groups were analyzed using generalized estimating equations. Multivariate regression tested the significance of relationships between pain scales and video analysis. Video analysis identified that one orthopedic behavior, namely 'Walking with full weight bearing' of the operated leg, decreased more in Group 1 at T24 (indicative of pain), whereas three behaviors indicative of sedation decreased in Group 2 at T24 (all p<0.004). Electrodermal activity was higher in Group 1 than in Groups 2 and 3 until T1 (p<0.0003). The VAS was not responsive. 4A-VET showed divergent results as its orthopedic component (4A-VETleg) detected lower pain in Group 2 until T12 (p<0.0009), but its interactive component (4A-VETbeh) was increased in Group 2 from T12 to T48 (p<0.001). Concurrent validity established that 4A-VETleg scores the painful orthopedic condition accurately and that pain assessment through 4A-VETbeh and VAS was severely biased by the sedative side-effect of the analgesics. Finally, the video analysis offered a concise template for assessment in dogs with acute orthopedic pain. However, subjective pain quantification methods and electrodermal activity need further investigation.

Retrospective single institution data suggest that postoperative pain after robot-assisted laparoscopic radical prostatectomy is decreased by early removal of the urethral catheter with suprapubic tube drainage. In a randomized patient population we determined whether suprapubic tube drainage with early urethral catheter removal would improve postoperative pain compared with urethral catheter drainage alone. Men with a body mass index of less than 40 kg/m(2) who had newly diagnosed prostate cancer and elected robot-assisted laparoscopic radical prostatectomy were included in analysis. Block randomization by surgeon was used and randomization assignment was done after completing the urethrovesical anastomosis. In patients assigned to suprapubic tube drainage the urethral catheter was removed on postoperative day 1 and all catheters were removed on postoperative day 7. Visual analog pain scale and satisfaction questionnaires were administered on postoperative days 0, 1 and 7. A total of 29 patients were randomized to the urethral catheter vs 29 to the suprapubic tube plus early urethral catheter removal at the time of interim futility analysis. Mean visual analog pain scale scores did not differ between the groups at any time point and a similar percent of patients cited the catheter as the greatest bother with nonsignificant differences in treatment related satisfaction. Complications during postoperative week 1 did not vary between the groups. Based on interim results the trial was terminated due to lack of effect. Patients randomized to suprapubic tube vs urethral catheter drainage for the week after prostatectomy had similar pain, catheter related bother and treatment related satisfaction in the perioperative period. We no longer routinely offer suprapubic tube drainage with early urethral catheter removal at our institution. Copyright © 2014 American Urological Association Education and Research, Inc.

Numerous postoperative pain protocols exist for patients undergoing total knee arthroplasty (TKA). We compared the length of stay, early range of motion (ROM), and pain scores of a control group with a femoral nerve block to those of a group with femoral nerve block and local infiltration analgesia following TKA. In a consecutive series of patients undergoing primary TKA at a Veteran's Administration hospital, 40 patients (40 TKAs) who had local infiltration analgesia were compared to a historical group of 43 patients (43 TKAs) who had a long-acting femoral nerve block without local infiltration analgesia. Local infiltration analgesia consisted of intraoperative injection of 150 mL of 300 mg ropivacaine, 30 mg ketorolac, and 500 μg epinephrine using 50 mL into each of 3 areas: (1) posterior capsule, (2) medial and lateral capsule, and (3) anterior capsule and subcutaneous tissues. A 17-gauge intra-articular catheter was used to inject an additional 100 mg of ropivacaine on postoperative day 1. The control group had a single-shot femoral nerve block using 150 mg of ropivacaine with epinephrine. Mean length of stay for the local infiltration analgesia group compared to controls was 3.2±1.4 days vs 3.8±1.6 days, respectively (P=.03). No significant differences existed in average ROM (6 weeks), discharge hematocrit, transfusions, and temperature. Mean pain scores were lower in the local infiltration analgesia group on postoperative day 1 (P=.04), but not on postoperative day 2 or 3. Maximum visual analog scale scores (P<.01) were reduced in the local infiltration analgesia group. Our early experience with local infiltration analgesia demonstrated a significantly reduced length of stay due to decreased postoperative pain. Copyright 2011, SLACK Incorporated.

One of the most frequent and distressing complications of the tension-free vaginal tape obturator (TVT-O) procedure for stress urinary incontinence (SUI) is groin pain, which may be related to the surgical technique or to the tape. The aim of this study was to evaluate the impact of a more limited dissection and a more medial trocar trajectory in TVT-O positioning on postoperative pain. Seventy-two SUI patients were randomized to undergo TVT-O either with the traditional technique (group A) or a modified procedure (reduced paraurethral dissection and a more medial trocar trajectory) (group B). Visual analog scale pain scores 12 h, 24 h, and 1 month after the procedure, number of analgesic vials, objective cure rate, and patient functional and quality of life scores 6 months after the procedure were evaluated. Data were analyzed by the Student's t test for parametric variables, the Mann-Whitney U and Wilcoxon tests for nonparametric variables, and Fisher's exact test for categorical variables. Pain scores were significantly lower in group B compared with group A 24 h after surgery (P = 0.01). Pain scores significantly decreased from 12-24 h postoperatively to 1 month follow-up in both groups (P < 0.001). No significant differences were observed in the number of analgesic vials administered, cure rates, and questionnaire scores between the two groups. More limited dissection and a more medial trocar trajectory of TVT-O seem to reduce postoperative groin pain at 24 h after the procedure, but not the analgesic requirement.

Open inguinal hernia repair is one of the most painful procedures in day surgery. A continuous ambulatory analgesic is thought to reduce postoperative pain when it is applied to the surgical site. The aim of this study is to evaluate the efficacy of local anesthetic infusion pump following open inguinal hernia repair for the reduction of postoperative pain. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that have investigated the outcomes of using an infusion pump for delivering a local anesthetic contrasted to a control group for open inguinal hernia repair. Pain was assessed from Day 1 to Day 5 following the surgery. The secondary outcomes included analgesia use and postoperative complications. We reviewed 5 trials that totaled 288 patients. The analgesic effects of bupivacaine (4 trials) and ropivacaine (one trial) were compared with a placebo group. The pooled mean difference in the score measuring the degree of pain diminished significantly at Day 1 to Day 4 in the experimental group. Two studies have reported that the number of analgesics required also decreased in the experimental group. No bupivacaine-related complication was reported. Our results revealed that applying a local anesthetic infusion pump following inguinal hernia repairs was more efficacious for reducing postoperative pain than a placebo. However, the findings were based on a small body of evidence in which methodological quality was not high. The potential benefits of applying a local anesthetic infusion pump to hernia repair must still be adequately investigated using further RCTs. Copyright © 2014 Surgical Associates Ltd.

It is reported that following abdominal surgery, transversus abdominis plane (TAP) block can reduce postoperative pain. The primary outcome of this study was the evaluation of the efficacy of TAP block on pain intensity following cesarean delivery with Pfannenstiel incision. Fifty pregnant women were randomized blindly to receive either a TAP block with 15 ml 0.25% bupivacaine in both sides (group T, n = 25) or no blockade (group C, n = 25) at the end of the surgery, which was performed with a Pfannenstiel incision under general anesthesia. The pain intensity in the patients was assessed by a blinded investigator at the time of discharge from recovery and at 6, 12, and 24 h postoperatively, with a visual analogue scale (VAS) for pain. The women in the TAP block group had significantly lower VAS pain scores at rest and during coughing and consumed significantly less tramadol than the women in group C [50 mg (0-150) vs. 250 mg (0-400), P = 0.001]. There was a significantly longer time to the first request for analgesic in the TAP block group [210 min (0-300) vs. 30 min (10-180) in group C, P = 0.0001]. Two-sided TAP block with 0.25% bupivacaine in parturients who undergo cesarean section with a Pfannenstiel incision under general anesthesia can decrease postoperative pain and analgesic consumption. The time to the first analgesic rescue was longer in the parturients who received the TAP block.

Thoracotomy results in severe postoperative pain potentially leading to chronic pain. We investigated the potential benefits of intravenous parecoxib on postoperative analgesia combined with thoracic epidural analgesia (TEA). Eighty-six patients undergoing thoracic surgery were randomized into two groups. Patient-controlled epidural analgesia (PCEA) was used until chest tubes were removed. Patients received parecoxib (group P) or placebo (group C) intravenously just 0.5 h before the operation and every 12 h after operation for 3 days. The intensity of pain was measured by using a visual analogue scale (VAS) and recorded at 2, 4, 8, 24, 48, 72 h after operation. The valid number of PCA, the side effects and the overall satisfaction to analgesic therapy in 72 h were recorded. Venous blood samples were taken before operation, the 1(st) and 3(rd) day after operation for plasma cortisol, adrenocorticotropic hormone (ACTH), interleukin-6 and tumor necrosis factor-α level. The occurrence of residual pain was recorded using telephone questionnaire 2 and 12 months after surgery. Postoperative pain scores at rest and on coughing were significantly lower with the less valid count of PCA and greater patient satisfaction in group P (P<0.01). Adverse effect and the days fit for discharge were comparable between two groups. The cortisol levels in placebo group were higher than parecoxib group at T2. The level of ACTH both decreased in two groups after operation but it was significantly lower in group P than that in group C. There were no changes in plasma IL-6 and TNF-α levels before and after analgesia at T1 and T2 (P>0.05). The occurrence of residual pain were 25% and 51.2% separately in group P and C 3 months postoperatively (P<0.05). Intravenous parecoxib in multimodal analgesia improves postoperative analgesia provided by TEA, relieves stress response after thoracotomy, and may restrain the development of chronic pain.

(i) To compare knowledge and compliance with good clinical practices regarding control of postoperative pain among nurses employed at hospitals with and without a "Hospital without Pain" certificate, (ii) to identify the determinants of nurses' knowledge and (iii) to define barriers to effective control of postoperative pain. Only a slight improvement in postoperative pain control has been observed recently, if any. Implementation of good clinical practices in the control of postoperative pain requires involvement of nurses. A cross-sectional study. The study included 257 nurses from hospitals with a "Hospital without Pain" certificate and 243 nurses from noncertified hospitals, with mean job seniority of 17.6 ± 9.6 years. All respondents answered 26 questions regarding postoperative pain control-related issues. Based on the answers, overall scores were calculated for (i) nurses' knowledge, (ii) compliance with good clinical practices and (iii) barriers to effective control of postoperative pain. Nurses from the certified hospitals presented with significantly higher levels of knowledge and compliance with good clinical practices and identified significantly more barriers to effective control of postoperative pain. Apart from certification of a hospital, better knowledge of postoperative pain control was determined by higher education, participation in postgraduate training programmes and other relevant courses, self-education from medical journals, employment at paediatric ward or intensive care unit. The most commonly reported barriers to effective control of pain included too low doses of painkillers prescribed by physicians and inability to modify the protocol of pain treatment by the nurse. Control of postoperative pain can be improved by enrolling nurses in various forms of continuous training and by providing them with greater autonomy in administering painkillers to surgical patients. Better quality of care offered to patients with postoperative pain can be achieved by continuous education of nurses and physicians, and greater compliance with relevant good clinical practices. © 2017 John Wiley & Sons Ltd.

Coblation: improving outcomes for children following adenotonsillectomy.

PubMed

Benninger, Michael; Walner, David

2007-01-01

Tonsillectomy and adenoidectomy, 2 of the most common childhood surgeries, are performed for a number of indications, the most common being airway obstruction caused by adenotonsillar hypertrophy. Other indications for tonsillectomy include recurrent pharyngotonsillitis, streptococcal carriage, recurrent peritonsillar abscess, halitosis, and presumed neoplasia. Although adenotonsillar surgery is a safe and effective technique for treating disease and obstruction, parents remain concerned about postoperative morbidity, for which the potential is much greater after tonsillectomy than adenoidectomy. Postoperative pain and hemorrhage are 2 unpleasant side effects that can prolong postoperative recovery. Surgeons use a variety of surgical techniques to remove the tonsils and adenoids. When compared with older techniques, such as cold steel dissection and monopolar electrocautery, a new technique named Coblation that uses lower temperatures than electrocautery to remove tonsil tissue and achieve hemostasis, has been shown to reduce pain and decrease postoperative narcotic use, leading to shorter recovery times and a quicker return to normal in children.

Background Variability in patients' postoperative pain experience and response to treatment challenges effective pain management. Variability in pain reflects individual differences in inhibitory pain modulation and psychological sensitivity, which in turn may be clinically relevant for the disposition to acquire pain. The aim of this study was to investigate the effects of conditioned pain modulation and situational pain catastrophizing on postoperative pain and pain persistency. Methods Preoperatively, 42 healthy males undergoing funnel chest surgery completed the Spielberger's State-Trait Anxiety Inventory and Beck's Depression Inventory before undergoing a sequential conditioned pain modulation paradigm. Subsequently, the Pain Catastrophizing Scale was introduced and patients were instructed to reference the conditioning pain while answering. Ratings of movement-evoked pain and consumption of morphine equivalents were obtained during postoperative days 2–5. Pain was reevaluated at six months postoperatively. Results Patients reporting persistent pain at six months follow-up (n = 15) were not significantly different from pain-free patients (n = 16) concerning preoperative conditioned pain modulation response (Z = 1.0, P = 0.3) or level of catastrophizing (Z = 0.4, P = 1.0). In the acute postoperative phase, situational pain catastrophizing predicted movement-evoked pain, independently of anxiety and depression (β = 1.0, P = 0.007) whereas conditioned pain modulation predicted morphine consumption (β = −0.005, P = 0.001). Conclusions Preoperative conditioned pain modulation and situational pain catastrophizing were not associated with the development of persistent postoperative pain following funnel chest repair. Secondary outcome analyses indicated that conditioned pain modulation predicted morphine consumption and situational pain catastrophizing predicted movement-evoked pain intensity in the acute postoperative phase. These findings may have important implications for developing strategies to treat or prevent acute postoperative pain in selected patients. Pain may be predicted and the malfunctioning pain inhibition mechanism as tested with CPM may be treated with suitable drugs augmenting descending inhibition. PMID:24587268

Background Pain is a major problem in patients after cesarean and medication such as aromatherapy which is a complementary therapy, in which the essences of the plants oils are used to reduce such undesirable conditions. Objectives In this study, the effect of aromatherapy using Lavender (Lavandula) essential oil on cesarean postoperative pain was assessed. Materials and Methods In a triple blind, randomized placebo-controlled trial study, 60 pregnant women who were admitted to a general hospital for cesarean section, were divided randomly into two groups. After cesarean, the Lavender group inhaled about 3 drops of 10% Lavender oil essence and the placebo group inhaled 3 drops of placebo after the start of postoperative pain, four, eight and 12 hours later, for 5 minutes from the 10 cm distance. Patient's pain was measured by the VAS (Visual Analog Scale) score before and after each intervention, and vital sign, complications and level of satisfaction of every patient were recorded before and after aromatherapy. Results There was no statistically significant difference between groups in age, height, weight, and time to the first analgesic requirement. Patients in the Lavender group had less postoperative pain in four (P = 0.008), eight (P = 0.024) and 12 (P = 0.011) hours after first medication than the placebo group. The decreased heart rate and patients' level of satisfaction with analgesia were significantly higher in the Lavender group (P = 0.001). In the placebo group, the use of diclofenac suppositories for complete analgesia was also significantly higher than the Lavender group (P = 0.008). Conclusions The inhaled Lavender essence may be used as a part of the multidisciplinary treatment of pain after cesarean section, but it is not recommended as the sole pain management. PMID:24223363

Patients in the Lavender group had less postoperative pain in four (P = 0.008), eight (P = 0.024) and 12 (P = 0.011) hours after first medication than the placebo group. The decreased heart rate and patients' level of satisfaction with analgesia were significantly higher in the Lavender group (P = 0.001). In the placebo group, the use of diclofenac suppositories for complete analgesia was also significantly higher than the Lavender group (P = 0.008). The inhaled Lavender essence may be used as a part of the multidisciplinary treatment of pain after cesarean section, but it is not recommended as the sole pain management.

Cranial electrotherapy stimulation (CES) is used as a treatment for depression and anxiety, and as an adjunctive intervention for pain management. This prospective study investigated whether CES could decrease preoperative anxiety, the injection pain of rocuronium, postoperative pain and stress hormone levels. Female patients undergoing thyroidectomy were randomly assigned to two groups, to receive either no pretreatment (control group) or CES pretreatment. Anxiety score, withdrawal response on rocuronium injection, and pain scores at 1, 4, 12 and 24 h post surgery were evaluated. Adrenocorticotrophic hormone (ACTH), cortisol and glucose levels were measured. Patients were blinded to the treatment condition. Fifty patients entered the study (n = 25 per group). Anxiety score and withdrawal responses during rocuronium injection were significantly reduced in the CES group compared with the control group. Pain score was significantly lower in the CES group than in the control group, 1 h and 4 h post surgery. There were no significant differences in ACTH, cortisol and glucose levels. CES pretreatment appears to reduce the level of preoperative anxiety, injection pain of rocuronium and postoperative pain. However, CES pretreatment did not affect stress hormone responses.

In our centre, the postoperative scoliosis rehabilitation consists in stabilizing postural and respiratory exercises lasting several hours a day (5 1/2 to 7 hours). Additionally to pain treatment, we apply pain physiotherapy, physical therapy, acupuncture and besides manual medicine, also a psychological intervention and pain treatment by medication. 46 patients suffered from heavier pain 10 or more years after scoliosis surgery. The patients reported their pain at the beginning and at the end of 3-6 week in-patient rehabilitation programme. We applied a visual analogous scale (VAS), a numerical scale (NS), a standardized adjective scale (VRS), and a pain frequency scale. All the patients with an average age of 36 years old (SD=16) and an average curve angle of 35 degrees thoracic (SD=36) and 26 degrees lumbar (SD=22) showed a decrease of the values on the pain intensity scale. Pain reduction was highly significant, as well as pain frequency. Chronic pain as a late result following scoliosis surgery can be reduced by an intensive in-patient rehabilitation, at least in the short term. There are further necessary studies in order to follow-up the long-term effect of postoperative rehabilitation.

Although femoral nerve block provides satisfactory analgesia after total knee arthroplasty (TKA), residual posterior knee pain may decrease patient satisfaction. We conducted a randomized controlled trial to clarify the efficacy of the sciatic nerve block (SNB) and local infiltration of analgesia with steroid (LIA) regarding postoperative analgesia after TKA, when administrated in addition to femoral nerve block (FNB). Seventy-eight patients were randomly allocated to the two groups: concomitant administration of FNB and SNB or FNB and LIA. The outcome measures included post-operative pain, passive knee motion, C-reactive protein level, time to achieve rehabilitation goals, the Knee Society Score at the time of discharge, patient satisfaction level with anesthesia, length of hospital stay, surgical time, and complications related to local anesthesia. The patients in group SNB showed less pain than group LIA only on postoperative hours 0 and 3. Satisfactory postoperative analgesia after TKA was also achieved with LIA combined with FNB, while averting the risks associated with SNB. The influence on progress of rehabilitation and length of hospital stay was similar for both anesthesia techniques. The LIA offers a potentially safer alternative to SNB as an adjunct to FNB, particularly for patients who have risk factors for sciatic nerve injury.

Specific aims included determining the difference in pain, anxiety, tension, and satisfaction scores of patients before and after massage compared with patients who received standard care. A randomized controlled trial comparing outcomes before and after intervention in and across groups. Saint Marys Hospital, Mayo Clinic, Rochester, Minnesota. Patients undergoing cardiovascular surgical procedures (coronary artery bypass grafting and/or valvular repair or replacement) (N=58). Patients in the intervention group received a 20-minute session of massage therapy intervention between postoperative days 2 and 5. Patients in the control group received standard care and a 20-minute quiet time between postoperative days 2 and 5. Linear Analogue Self-assessment scores for pain, anxiety, tension, and satisfaction. Statistically and clinically significant decreases in pain, anxiety, and tension scores were observed for patients who received a 20-minute massage compared with those who received standard care. Patient feedback was markedly positive. This pilot study showed that massage can be successfully incorporated into a busy cardiac surgical practice. These results suggest that massage may be an important therapy to consider for inclusion in the management of postoperative recovery of cardiovascular surgical patients. Copyright 2009 Elsevier Ltd.

To determine whether ketamine added to morphine or hydromorphone patient-controlled analgesia (PCA) provides clinically relevant reductions in postoperative pain, opioid requirements, and adverse events when compared with morphine or hydromorphone PCA in adults undergoing surgery. We systematically searched six databases up to June 2, 2015 for randomized controlled trials (RCTs) comparing ketamine plus morphine/hydromorphone PCA vs morphine/hydromorphone PCA for postoperative pain in adults. Thirty-six RCTs including 2,502 patients proved eligible, and 22 of these were at low risk of bias. The addition of ketamine to morphine/hydromorphone PCA decreased postoperative pain intensity at six to 72 hr when measured at rest (weighted mean difference [WMD] on a 10-cm visual analogue scale ranged from -0.4 to -1.3 cm) and during mobilization (WMD ranged from -0.4 to -0.5 cm). Adjunctive ketamine also significantly reduced cumulative morphine consumption at 24-72 hr by approximately 5-20 mg. Predefined subgroup analyses and meta-regression did not detect significant differences across subgroups, including a dose-response relationship. There was no significant difference in patient satisfaction scores at 24 and 48 hr. Nevertheless, the addition of ketamine to morphine/hydromorphone PCA significantly reduced postoperative nausea and vomiting (relative risk, 0.71; 95% confidence interval [CI], 0.60 to 0.85; absolute risk reduction, 8.9%; 95% CI, 4.6 to 12.2). Significant effects on other adverse events (e.g., hallucinations, vivid dreams) were not detected, though only a few studies reported on them. Adding ketamine to morphine/hydromorphone PCA provides a small improvement in postoperative analgesia while reducing opioid requirements. Adjunctive ketamine also reduces postoperative nausea and vomiting without a detected increase in other adverse effects; however, adverse events were probably underreported.

Comparison of the effects of treatment with celecoxib, loxoprofen, and acetaminophen on postoperative acute pain after arthroscopic knee surgery: A randomized, parallel-group trial.

Selective cyclooxygenase-2 (COX-2) inhibitors, conventional non-selective nonsteroidal anti-inflammatory drugs (NSAIDs), and acetaminophen have been adopted for the relief of mild to moderate acute and chronic pain. However, it remains unclarified whether the therapeutic differences in pain sensation exist among these agents. The aim of this study was to compare the efficacy of different types of analgesic agents for postoperative acute pain management. A single-center, randomized, controlled study was performed in consecutive patients who underwent the second-look procedure with removal of internal fixation after anterior cruciate ligament reconstruction or arthroscopic meniscal repair/meniscectomy. Celecoxib (400 mg for the first dose and then 200 mg), loxoprofen (60 mg), or acetaminophen (600 mg) was orally administered from postoperative 3 h. The pain intensity on a 100-mm VAS scale and subjective assessment of therapeutic pain-relief were compared among these three treatment groups until postoperative 2 days. The acquired data were analyzed according to the per-protocol analysis principle. A total of 432 patients were screened, and 160 were enrolled. The VAS score tended to decrease over time in all groups. There was a significant improvement in the pain score both at rest and on movement, and subjective impression in the celecoxib-treated group compared with acetaminophen at postoperative 2 days. On the other hand, loxoprofen resulted in the benefit only in the pain score at rest in comparison with acetaminophen. Any comparisons between celecoxib and loxoprofen showed insignificant differences throughout observations. No adverse effects were confirmed in each group. These obtained findings in our dose setting conditions suggest that celecoxib and loxoprofen treatments were superior to acetaminophen in pain-relief, though the superiority of loxoprofen over acetaminophen was modest. Overall, selective COX-2 inhibitors including conventional NSAIDs seem to have a possible advantage in acute pain management of relatively less invasive surgery.

Pain following hysterectomy: epidemiological and clinical aspects.

PubMed

Brandsborg, Birgitte

2012-01-01

It is well known that different surgical procedures like amputation, thoracotomy, inguinal herniotomy, and mastectomy are associated with a risk of developing chronic postsurgical pain. Hysterectomy is the most frequent gynecological procedure with an annual frequency of 5000 hysterectomies for a benign indication in Denmark, but is has not previously been documented in detail to what extent this procedure leads to chronic pain. The aim of this PhD thesis was therefore to describe the epidemiology, type of pain, risk factors, and predictive factors associated with chronic pain after hysterectomy for a benign indication. The thesis includes four papers, of which one is based on a questionnaire study, two are based on a prospective clinical study, and one is a review of chronic pain after hysterectomy. The questionnaire paper included 1135 women one year after hysterectomy. A postal questionnaire about pain before and after hysterectomy was combined with data from the Danish Hysterectomy Database. Chronic postoperative pain was described by 32%, and the identified risk factors were preoperative pelvic pain, previous cesarean section, other pain problems and pain as an indication for hysterectomy. Spinal anesthesia was associated with a decreased risk of having pain after one year. The type of surgery (i.e. abdominal or vaginal hysterectomy) did not influence chronic pain. The prospective paper included 90 women referred for a hysterectomy on benign indication. The tests were performed before, on day 1, and 4 months after surgery and included questionnaires about pain, coping, and quality of life together with quantitative sensory testing of pain thresholds. Seventeen percent had pain after 4 months, and the risk factors were preoperative pain problems elsewhere and a high intensity of acute postoperative pain. Type of surgery was not a risk factor. Preoperative brush-evoked allodynia, pinprick hyperalgesia, and vaginal pain threshold were associated with a high intensity of acute postoperative pain, and preoperative brush-evoked allodynia was also associated with pelvic pain after 4 months. This PhD thesis shows that chronic postoperative pain is present after hysterectomy in 17-32% of women. The identified main risk factors are described above. The findings indicate that it is not the nerve injury itself, but more likely the underlying individual susceptibility to pain that is important for the development of chronic pain after hysterectomy.

The recovery of patients undergoing total shoulder arthroplasty (TSA) can be adversely affected by a number of complications. Autologous platelet gel (APG), produced by activating platelet-rich plasma (PRP), has been shown to improve hemostasis and wound healing and reduce infections in some surgical procedures. Activated platelet-poor plasma (PPP) has also been used as a hemostatic agent. This study examines the effects of APG and PPP treatment on TSA patients postoperatively. After Institutional Review Board (IRB) approval, 40 patients undergoing TSA at our institution were prospectively enrolled in our study. They were randomized into either a control (n = 20) or study (n = 20) group, with the study group receiving APG and PPP treatment. Preoperative demographic data, pre- and postoperative laboratory data, pain scores, pain medication, complications, pre- and postoperative range of motion measurements, and postoperative lengths of stay were recorded for each group. The preoperative internal rotation index was significantly higher in the control group compared with treatment patients (4.64 +/- 4.46 vs. 1.88 +/- 2.44, p < .05). The percent hemoglobin retained postoperatively was higher in the treatment group at 24 (84.54 +/- 5.32 vs. 79.87 +/- 8.73) and 72 hours (87.46 +/- 16.03 vs. 76.70 vs. 5.96), but neither difference reached statistical significance. The treatment group had significantly lower pain scores (p = .007) and total fentanyl requirements (p < .05) compared with control patients. The internal rotation index improvement factor (postoperative internal rotation index/preoperative internal rotation index) was significantly higher in the treatment group vs. the control group (p < .05). Although it did not reach statistical significance, the treatment group was discharged almost 9 hours earlier than the control group (64.44 +/- 15.23 vs. 73.39 +/- 15.37). APG and PPP treatment decreased pain and provided a greater increase in internal rotation measurements postoperatively.

[A multimodal and multidisciplinary postoperative pain management concept].

Under-treatment of acute postoperative pain can lead to chronic pain with neuronal plasticity and result in poor surgical outcomes. A multimodal approach is therefore necessary to reduce postoperative pain by combining various analgesics with a non-pharmacological strategy. The current use of multimodal approaches, even for the management of postoperative pain, can reduce the side effects of pharmaceutical therapy alone as well as reducing the length of hospital stay. Adequate pain control is an important prerequisite for the application of rehabilitation programmes and will thereby influence functional outcome. In addition, patient satisfaction, as a major benchmarking factor after surgical treatment, is significantly influenced by the quality of postoperative pain management.

Background Non-steroidal anti-inflammatory drugs are often used as components of multimodal therapy for postoperative pain management, but their use is currently limited by its side effects. The specific objective of this study was to evaluate the efficacy and safety of a new formulation of intravenous (IV) ibuprofen for the management of postoperative pain in a European population. Methods and Findings A total of 206 patients from both abdominal and orthopedic surgery, were randomly assigned in 1:1 ratio to receive 800 mg IV-ibuprofen or placebo every 6 hours; all patients had morphine access through a patient controlled analgesia pump. The primary outcome measure was median morphine consumption within the first 24 hours following surgery. The mean±SEM of morphine requirements was reduced from 29,8±5,25 mg to 14,22±3,23 mg (p = 0,015) and resulted in a decrease in pain at rest (p = 0,02) measured by Visual Analog Scale (VAS) from mean±SEM 3.34±0,35 to 0.86±0.24, and also in pain during movement (p = 0,02) from 4.32±0,36 to 1.90±0,30 in the ibuprofen treatment arm; while in the placebo group VAS score at rest ranged from 4.68±0,40 to 2.12±0,42 and during movement from 5.66±0,42 to 3.38±0,44. Similar treatment-emergent adverse events occurred across both study groups and there was no difference in the overall incidence of these events. Conclusions Perioperative administration of IV-Ibuprofen 800 mg every 6 hours in abdominal surgery patient’s decreases morphine requirements and pain score. Furthermore IV-Ibuprofen was safe and well tolerate. Consequently we consider appropriate that protocols for management of postoperative pain include IV-Ibuprofen 800 mg every 6 hours as an option to offer patients an analgesic benefit while reducing the potentially risks associated with morphine consumption.

Trochlear dysplasia is a major risk factor predisposing to patellar instability and has been reported to occur in up to 85% of patients with recurrent patellar dislocation. Different operative techniques have been described to correct trochlear dysplasia, including the Bereiter technique, in which subchondral bone is removed and the cartilage can be compressed into a U-shaped groove. The hypothesis was that after a Bereiter-type trochleoplasty combined with medialisation of the tibial tubercle and MPFL reconstruction, patellar pain and instability decreased and anatomic reconstruction can be seen radiographically after 5-year follow-up. Between 2004 and 2011, a combined procedure including Bereiter-type trochleoplasty was performed on 21 consecutively included patients (22 knees) with objective patellar instability and severe trochlear dysplasia. Instability and pain were assessed preoperatively and 3, 6, 12, 24 and 60 months postoperatively with the visual analogue scale (VAS) for pain and instability, Kujala, International Knee Documentation Committee Subjective Knee Evaluation (IKDC SKE) and Short Form Health Survey (SF-36). Pre- and postoperatively, a true lateral radiograph was made to investigate the presence of the crossing sign and to measure the trochlear bump and trochlear depth, as well as a sunrise patella view to measure the sulcus angle. VAS pain and instability, Kujala and IKDC SKE improved significantly 5 years after trochleoplasty (p < 0.05). SF-36 showed no significant improvement. None of the patients reported patellar dislocations postoperatively. Sport activities remained limited. Postoperative radiographs showed no crossing sign. There was a significant increase in trochlear depth (p < 0.0001) and also a significant decrease in trochlear bump and sulcus angle (both p < 0.0001). A combined procedure consisting of Bereiter-type trochleoplasty, medialisation of the tibial tubercle and MPFL reconstruction in patients with objective patellar instability and severe trochlear dysplasia resulted in a clear decrease of pain and instability. Radiological assessment showed anatomical reconstruction. Nevertheless, residual symptoms remain and the possibility of future cartilage damage is uncertain. IV.

We conducted a retrospective comparison of surgical treatment outcomes for acute Achilles tendon ruptures in nonobese and obese patients. Between October 2006 and April 2014, we studied 76 patients with acute midsubstance Achilles tendon rupture: 44 nonobese and 32 obese (body mass index >30 kg/m). Preoperative and postoperative function and pain were graded with the Foot and Ankle Ability Measure (FAAM) Sports subscale and the visual analog scale for pain, respectively. All 76 patients presented for follow-up. On a scale of 100, the mean FAAM score for the nonobese patients increased from 38.1 preoperatively to 90.2 at final visit, and on a scale of 10, the mean pain score decreased from 7.1 preoperatively to 1.6 at latest follow-up. For obese patients, the mean FAAM score increased from 34.2 preoperatively to 83.3 at final visit, and the mean pain score decreased from 6.2 preoperatively to 1.9 at the latest follow-up. The postoperative scores of the two groups were not significantly different (P > 0.05). Postoperative wound complications developed in six nonobese patients and one obese patient (13.6% and 3.1%, respectively; P < 0.05). To our knowledge, comparing outcomes from surgically treated acute Achilles ruptures in nonobese and obese patients has not been previously reported. We found that both obese and nonobese patients can achieve improved Achilles tendon function and pain as a result of surgery. The findings of this study demonstrate that both nonobese and obese patients can achieve a high rate of improvement in ankle function and pain relief after surgical repair of the Achilles tendon.

Most models of acute post-operative orthopedic pain involve the injection of a clinically irrelevant pro-inflammatory agent. The ideal model should, however, be clinically relevant and allow full functional recovery of enrolled animals after research is completed. This study explored the validity of a model employing arthrotomy and objectively measured limb use. Six purpose-bred Beagles underwent arthrotomies on each stifle with a washout period in between. Using a randomized crossover design, each dog received placebo and an extended-release buprenorphine (ER-Bup) preparation. Static and dynamic ground reaction forces (GRFs) were measured prior to and for 72 h following surgery using a pressure sensitive walkway (PSW). GRFs for each hind limb were compared using difference (delta), and symmetry indices (SI). The effects of surgery and of treatment were analyzed using repeated measures ANCOVA. The results indicated significantly decreased limb use compared to baseline for placebo, and significantly increased limb use in the ER-Bup group over placebo at all times for % bodyweight distribution (%BWdistrib), peak vertical force (PVF) and vertical impulse (VI). There was a significant treatment by time interaction for velocity (P = 0.03) and %BWdistrib (P = 0.01, 0.003). Overall, the data show that reduced limb use was present for at least 72 h following arthrotomy. In addition, the use of the ER-Bup analgesic decreased lameness, confirming the validity of this approach as a model of post-operative pain. Subjective assessments did not detect the pain-inducing effects of arthrotomy or pain-alleviating effects of treatment, and subjective measures of procedural pain in research dogs need to be developed.

To examine parents' knowledge about and attitudes towards pain management, use of pain relief strategies and satisfaction with their children's postoperative pain management, as well as the relationships among these variables. Children's postoperative pain is inadequately managed worldwide. Despite increasing emphasis on parental involvement in children's postoperative pain management, few studies have examined parents' management of their child's postoperative pain in Singapore. A descriptive correlational study. A convenience sample of 60 parents having 6- to 14-year-old children undergoing inpatient elective surgery in a public hospital in Singapore was recruited. Data were collected one day after each child's surgery using the Pain Management Knowledge and Attitudes questionnaire and the Parents' Use of Pain Relief Strategies questionnaire. Descriptive statistics, Mann-Whitney U tests, Kruskal-Wallis tests and Spearman's rank correlation coefficient were used for data analyses. Parents displayed moderate levels of knowledge, attitudes and use of pain relief methods in relation to their children's postoperative pain and pain management. They were generally satisfied with the management of their child's postoperative pain. There was significant difference in Parents' Use of Pain Relief Strategies scores between parents with and without previous experience of caring for their hospitalised child. Statistically significant positive correlations were found between parents' knowledge and attitude, knowledge and satisfaction, attitude and satisfaction, knowledge and pain relief strategies, as well as attitude and pain relief strategies. This study indicates the need to provide parents with more information regarding their children's postoperative pain management. Future studies are needed to develop educational interventions for parents to improve their knowledge and attitudes, which will eventually improve their use of pain relief strategies for their children. Health professionals need to provide more information to equip parents with knowledge and skills regarding paediatric postoperative pain management. © 2015 John Wiley & Sons Ltd.

OBJECTIVE Pain control is an important clinical consideration and quality-of-care metric. No studies have examined postoperative pain control following transsphenoidal surgery for pituitary lesions. The study goals were to 1) report postoperative pain scores following transsphenoidal surgery, 2) determine if multimodal opioid-minimizing pain regimens yielded satisfactory postoperative pain control, and 3) determine if intravenous (IV) ibuprofen improved postoperative pain scores and reduced opioid use compared with placebo. METHODS This study was a single-center, randomized, double-blinded, placebo-controlled intervention trial involving adult patients with planned transsphenoidal surgery for pituitary tumors randomized into 2 groups. Group 1 patients were treated with scheduled IV ibuprofen, scheduled oral acetaminophen, and rescue opioids. Group 2 patients were treated with IV placebo, scheduled oral acetaminophen, and rescue opioids. The primary end point was patient pain scores (visual analog scale [VAS], rated 0-10) for 48 hours after surgery. The secondary end point was opioid use as estimated by oral morphine equivalents (OMEs). RESULTS Of 136 patients screened, 62 were enrolled (28 in Group 1, 34 in Group 2). The study was terminated early because the primary and secondary end points were reached. Baseline characteristics between groups were well matched except for age (Group 1, 59.3 ± 14.4 years; Group 2, 49.8 ± 16.2 years; p = 0.02). Mean VAS pain scores were significantly different, with a 43% reduction in Group 1 (1.7 ± 2.2) compared with Group 2 (3.0 ± 2.8; p < 0.0001). Opioid use was significantly different, with a 58% reduction in Group 1 (26.3 ± 28.7 mg OME) compared with Group 2 (62.5 ± 63.8 mg OME; p < 0.0001). CONCLUSIONS Multimodal opioid-minimizing pain-management protocols resulted in acceptable pain control following transsphenoidal surgery. IV ibuprofen resulted in significantly improved pain scores and significantly decreased opioid use compared with placebo. Postoperative multimodal pain management, including a nonsteroidal antiinflammatory medication, should be considered after surgery to improve patient comfort and to limit opioid use.

Background Recently, the use of smartphones to deliver health-related content has experienced rapid growth, with more than 165,000 mobile health (mHealth) apps currently available in the digital marketplace. With 3 out of 4 Canadians currently owning a smartphone, mHealth apps offer opportunities to deliver accessible health-related knowledge and support. Many individuals experience pain after surgery, which can negatively impact their health-related quality of life, including sleep, emotional, and social functioning. Smartphone apps that provide remote real-time monitoring and symptom management have the potential to improve self-management skills in patients experiencing postoperative pain. Increased confidence and practice of self-management skills could contribute to decreased postoperative pain and reduce risk of developing persistent pain. Published reviews of general pain self-management apps demonstrate a lack of evidence-based content, theoretical grounding, and health care professional involvement. However, no review to date has focused on the app marketplace specific for individuals with postoperative pain. Objective The aim of this study was to characterize and critically appraise the content and functionality of commercially available postoperative pain self-management apps. Methods An electronic search and extraction was conducted between December 2016 and March 2017 of the official Canadian app stores for the three major smartphone operating systems (iPhone operating system [iOS], Android, and Windows). Stores were searched separately using predetermined search terms. Two authors screened apps based on information provided in the public app description. Metadata from all included apps were abstracted into a standard spreadsheet. Two authors verified the data with reference to the apps and downloaded apps themselves. The content and functionality of each app as it pertained to postoperative pain self-management was rated. Results A total of 10 apps met the inclusion criteria. All included apps were designed exclusively for the Android platform. Education was the most common self-management feature offered (8/10, 80%), with none of the apps offering features related to goal setting or social support. Overall, no single app was comprehensive in terms of pain self-management content. Five (50%) apps reported the involvement of a health care provider in their development. However, not a single app involved end users in their development, and none of the apps underwent scientific evaluation. Additionally, none of the apps were designed for use in pediatric patients. Conclusions Currently available postoperative pain apps for patients lack evidence-based content, goal setting, and social support functions. There is a need to develop and test comprehensive theory-based apps to support patients with pain self-management care following surgery. PMID:29061558

The content and functionality of each app as it pertained to postoperative pain self-management was rated. A total of 10 apps met the inclusion criteria. All included apps were designed exclusively for the Android platform. Education was the most common self-management feature offered (8/10, 80%), with none of the apps offering features related to goal setting or social support. Overall, no single app was comprehensive in terms of pain self-management content. Five (50%) apps reported the involvement of a health care provider in their development. However, not a single app involved end users in their development, and none of the apps underwent scientific evaluation. Additionally, none of the apps were designed for use in pediatric patients. Currently available postoperative pain apps for patients lack evidence-based content, goal setting, and social support functions. There is a need to develop and test comprehensive theory-based apps to support patients with pain self-management care following surgery. ©Chitra Lalloo, Ushma Shah, Kathryn A Birnie, Cleo Davies-Chalmers, Jordan Rivera, Jennifer Stinson, Fiona Campbell.

Preconditioning gas by humidification and warming the pneumoperitoneum improves laparoscopic outcomes. This prevents peritoneal desiccation and detrimental events related to traditional cold-dry gas. Few comparisons have been done comparing traditional cold-dry, heated-only, and humidified-warmed carbon dioxide. A prospective, controlled, randomized, double-blind study of laparoscopic gastric banding included 113 patients and compared traditional dry-cold (n=35) versus dry-heated (n=40), versus humidified-warm gas (n=38). Pain medications were standardized for all groups. Endpoints were recovery room length of stay, pain location, pain intensity, and total pain medications used postoperatively for up to 10 days. The humidified-warmed group had statistically significant differences from the other 2 groups with improvement in all end points. The dry-heated group had significantly more pain medication use and increased shoulder and chest pain than the other 2 groups had. Using warm-humidified gas for laparoscopic gastric banding reduces shoulder pain, shortens recovery room length of stay, and decreases pain medication requirements for up to 10 days postoperatively. Dry-heated gas may cause additional complications as is indicated by the increase in pain medication use and pain intensity.

Intraperitoneal local anesthetics have been shown to improve postoperative pain after laparoscopic cholecystectomy (LC). However, the choice of local anesthetic agent is debatable. We compared the analgesic efficacy of intraperitoneal lignocaine (lidocaine) versus bupivacaine after elective LC. We conducted a double-blind, randomized, controlled trial. We randomized consecutive patients undergoing LC into two groups. Group L received 10 mL 2% lignocaine (lidocaine), whereas Group B received 10 mL 0.5% bupivacaine, each diluted in 10 mL normal saline. All patients underwent standard perioperative anesthesia and analgesia protocol. We assessed patients at 0, 4, 8, 12, and 24 h postoperatively for pain using the visual analogue scale and verbal rating scale, and the need for additional analgesic medications. We analyzed a total of 206 patients: 106 in Group L and 100 in Group B. Demographic details were similar between groups (P > 0.05). Abdominal pain decreased significantly with time in both groups, with a similar mean response profile (P < 0.001). There was no statistically significant difference between groups with regard to abdominal or shoulder pain by both visual analogue scale and verbal rating scale at all five time intervals (P > 0.05). There was also no significant difference in the side effect profile of both drugs (P > 0.05). A lower proportion of patients in Group B required additional narcotic analgesia (87%) compared with Group L (94%). This difference was marginally significant (P = 0.057). Bupivacaine and lignocaine (lidocaine) are both safe and equally effective at decreasing postoperative pain after LC. Copyright © 2012 Elsevier Inc. All rights reserved.

To evaluate the advantageous anesthetic properties, such as the decrease of intraoperative analgesic requirement, time to extubation and recovery, and early postoperative pain, of dexmedetomidine used as hypotensive agent compared with nitroglycerin in orthognathic surgery. The authors implemented a prospective, single-blinded, randomized clinical trial. The sample was composed of healthy patients who were admitted for bimaxillary osteotomies and were assigned to 1 of 2 groups by a computer-generated random number and blinded to the group. Dexmedetomidine or nitroglycerin was used as the hypotensive drug for each group. All patients underwent hypotensive anesthesia and surgery according to standard protocol. Intraoperative amount of fentanyl, time to eye opening, time to follow basic verbal commands, time to extubation, early postoperative pain scores, and analgesics were recorded. Compared means were analyzed using the unpaired Student t test. A 2-sided statistical test was used. A P value less than .05 was considered significant. The sample was composed of 40 participants. The intraoperative fentanyl requirement was significantly lower in the dexmedetomidine group than in the nitroglycerin group (168.75±56.29 and 222.50±96.12 μg, respectively; P=.037). Times to eye opening and following commands were considerably longer in the dexmedetomidine group, but the time to extubation showed no meaningful difference. Early postoperative pain after 30 and 60 minutes and the requirement for meperidine were not meaningfully different between the 2 groups. Dexmedetomidine, used as a hypotensive drug, has anesthetic benefits compared with nitroglycerin. Dexmedetomidine decreases the intraoperative fentanyl requirement and does not meaningfully change the time to extubation, early postoperative pain, and analgesic drug requirement.

The case of a patient who experienced extravasation while receiving amiodarone via a peripheral infusion and was treated with intradermal hyaluronidase is reported. A 60-year-old Caucasian man arrived at the emergency department after a motor vehicle collision. The patient was noted to have a subdural hematoma, multiple rib fractures, sternal body fracture, abdominal wall injury, left clavicle fracture, right humerus fracture, and vertebral fractures. His medical history included hypertension, atrial fibrillation, and stroke with residual right-sided weakness. On postoperative day 1, the patient developed atrial fibrillation and was started on i.v. amiodarone. Treatment resulted in conversion to sinus rhythm, but the patient again developed atrial fibrillation on postoperative day 5. During the morning hours of postoperative day 6, the patient experienced a peripheral i.v. line extravasation of amiodarone in his left arm. The amiodarone drip was discontinued, and amiodarone 400 mg orally twice daily was started. The nursing staff was instructed to treat the patient for the amiodarone extravasation with traditional nonpharmacologic measures, including warm compresses and elevation of the extremity. After extravasation, the patient reported severe pain at the site. Due to the patient's continued complaints of pain and the expanding area of induration, the interdisciplinary team elected to proceed with intradermal hyaluronidase. The patient reported significantly decreased pain and was discharged to inpatient rehabilitation on postoperative day 10 without any significant adverse effects. Administration of intradermal hyaluronidase after amiodarone extravasation was associated with decreased expansion of erythema and warmth as well as an improvement in patient-reported pain scores without any noted adverse effects.

In recent years, thoracic wall nerve blocks, such as the pectoral nerve (PECS) block and the serratus plane block have become popular for peri-operative pain control in patients undergoing breast cancer surgery. The effect of PECS block on quality of recovery (QoR) after breast cancer surgery has not been evaluated. To evaluate the ability of PECS block to decrease postoperative pain and anaesthesia and analgesia requirements and to improve postoperative QoR in patients undergoing breast cancer surgery. Randomised controlled study. A tertiary hospital. Sixty women undergoing breast cancer surgery between April 2014 and February 2015. The patients were randomised to receive a PECS block consisting of 30 ml of levobupivacaine 0.25% after induction of anaesthesia (PECS group) or a saline mock block (control group). The patients answered a 40-item QoR questionnaire (QoR-40) before and 1 day after breast cancer surgery. Numeric Rating Scale score for postoperative pain, requirement for intra-operative propofol and remifentanil, and QoR-40 score on postoperative day 1. PECS block combined with propofol-remifentanil anaesthesia significantly improved the median [interquartile range] pain score at 6 h postoperatively (PECS group 1 [0 to 2] vs. Control group 1 [0.25 to 2.75]; P = 0.018]. PECS block also reduced propofol mean (± SD) estimated target blood concentration to maintain bispectral index (BIS) between 40 and 50 (PECS group 2.65 (± 0.52) vs. Control group 3.08 (± 0.41) μg ml; P < 0.001) but not remifentanil consumption (PECS group 10.5 (± 4.28) vs. Control group 10.4 (± 4.68) μg kg h; P = 0.95). PECS block did not improve the QoR-40 score on postoperative day 1 (PECS group 182 [176 to 189] vs. Control group 174.5 [157.75 to 175]). In patients undergoing breast cancer surgery, PECS block combined with general anaesthesia reduced the requirement for propofol but not that for remifentanil, due to the inability of the PECS block to reach the internal mammary area. Further, PECS block improved postoperative pain but not the postoperative QoR-40 score due to the factors that cannot be measured by analgesia immediately after surgery, such as rebound pain. This trial is registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN000013435).

To evaluate if preincision infiltration with extended-release liposomal bupivacaine provides improved overall pain relief compared with 0.25% bupivacaine after laparoscopic or robotic-assisted hysterectomy. A single-center double-masked randomized controlled trial (Canadian Task Force Classification I). A tertiary-care community hospital. Patients recruited from July 2015 through January 2016. Sixty-four patients were randomized, and 59 were analyzed for the primary outcome. Women scheduled to undergo multiport laparoscopic or robotic-assisted total hysterectomy for benign indications were randomized to receive preincision infiltration with undiluted liposomal bupivacaine or 0.25% bupivacaine. The primary outcome was overall average pain intensity by numeric rating scale (0-10) using the Brief Pain Inventory (BPI) via telephone survey on postoperative day (POD) 3. A sample size of 28 per group (N = 56) was planned to detect a 30% change in pain scores. Secondary outcomes were overall average and worst numeric pain scores on PODs 1, 2, and 14; pain scores in hospital; BPI pain interference scores; and total opioid use. There were no demographic differences between the 2 groups. For the primary outcome, we found a decrease in the average (p = .02) pain scores on POD 3 in the liposomal bupivacaine group. We also found a decrease in worst pain scores on POD 2 (p = .03) and POD 3 (p = .01). There were no differences in pain scores while in the hospital or on POD 1 or POD 14. There were no differences in BPI pain interference scores, opioid use, or reported adverse effects. For laparoscopic and robotic-assisted multiport hysterectomies, there is evidence of decreased average postoperative pain with liposomal bupivacaine compared with 0.25% bupivacaine for port-site analgesia on POD 3, but no difference in opioid use or measures of functioning.

The present authors examined the effects of listening to music on psychophysiological parameters (blood pressure, heart rate, and respiratory rate) during preoperative and postoperative days and determined whether listening to music could lower pain intensity and opioid dosage during postoperative days in patients who underwent total knee replacements. This was a two group repeated measures design for 30 subjects aged 53-85 years who were scheduled for total knee replacement. Subjects were randomly assigned to either a music group or a control group. Psychophysiological parameters were obtained from patients' monitors. A visual analog scale was used to assess postoperative pain. Opioid dosage was recorded and converted to standardized units. Mann-Whitney U-test and generalized estimating equation analysis were used to compare groups. Respiratory rates while in the surgical waiting area were lower for the music group than for the control group (P = 0.02). There was no significant difference between these groups for blood pressure, heart rate, pain intensity, or opioid dosage. However, a within-group comparison showed that systolic blood pressure in the music group was significantly and consistently decreased during postoperative recovery (Wald = 9.21, P = 0.007). These results suggest that listening to music stabilized systolic blood pressure in patients during postoperative recovery. However, the effects of music on psychophysiological parameters, pain intensity, and opioid dosage in a surgical setting require further research. © 2015 The Authors.

The purpose of this study was to evaluate the value of Chinese herbal fumigation in the postoperative anal disease. The authors randomly divided 348 patients into treatment group and control group with 174 cases in each group. The treatment group was given to the Chinese herbal medicine hemorrhoids lotion for fumigation based on conventional anti infective therapy, routine dressing change and relaxing bowel. The control group was given to 1 000 mL 1: 5 000 potassium permanganate solution for sitz bath, fumigation based on conventional anti infective therapy, routine dressing change and relaxing bowel. The pain score, edema score, bleeding score, granulation tissue growth score and wound healing time of two groups were compared after operation. The results showed that the postoperative 6 h pain scores were higher in the two groups, the postoperative 3,5,7 d pain scores gradually decreased, the difference was statistically significant (P < 0.05). The difference of postoperative 6 h pain scores was no significant difference between the two groups, while postoperative 3,5,7 d pain scores in the treatment group were significantly lower than those in the control group (P < 0.05). 7 days after operation, anal margin of edema score and blood in the stool score in the treatment group were lower than those in control group, meat medicine growth score was higher than that of the control group, the difference had statistical meaning (P < 0.05). The healing time of two groups was respectively (13.89 + 2.78), (18.45 + 1.65) d (P < 0.05). This study suggested that Chinese herbal fumigation and washing could reduce the pain degree of patients, the anal margin of edema, and the blood in the stool, also could promote granulation tissue growth and shorten the time of wound healing, deserve the clinical expansion.

There is increasing interest in local infiltration analgesia (LIA) to reduce postoperative pain with knee surgery. Despite widespread use of LIA, wide variations in drug combinations, infiltration techniques, and the concomitant use of systemic analgesics have made it difficult to determine the optimal drug combination for LIA.Using a previously validated animal knee surgery model, we aimed to determine the optimal combination of medications to reduce postoperative pain, and the best anatomical location and timing for local drug injection during surgery. Knee surgery was performed in an adult rat model under isoflurane anesthesia. During surgery, combinations of bupivacaine, ketorolac, dexamethasone, and morphine were injected around the knee and compared to saline placebo. Similar medications were injected systemically as a comparator group. Postoperative pain was assessed by measuring spontaneous rearing activity. Injections were given after bone drilling and/or just before wound closure. The 3-drug LIA combination of bupivacaine, ketorolac, and dexamethasone increased rearing (decreased pain) at 2 hours (P = 0.0198) and 24 hours (P = 0.0384) postsurgery compared to saline. The same drugs injected systemically had no effect. The ketorolac/dexamethasone combination for LIA was also effective at 2 hours (P = 0.0006) and 24 hours (P = 0.0279), and ketorolac alone reduced pain at 2 hours (P = 0.0045). Bupivacaine alone was less effective, and the addition of morphine had no effect. The 3-drug combination infiltrated just after creating holes in bone was more effective than when given into the wound just before wound closure. Our animal study suggests that clinical trials with LIA combinations of local anesthetic, nonsteroidal anti-inflammatory drug, and corticosteroid might be useful for reducing postoperative pain after knee surgery, with the nonsteroidal anti-inflammatory drug having the greatest effect.Perioperative physicians should consider delivering LIA earlier during the procedure as opposed to solely at the time of wound closure.

Prior studies have evaluated only the prolonged use of cryotherapy as a nonpharmacologic pain intervention. The purpose of this study was to determine whether a 30-minute application of cryotherapy at the time pain medication was given after a total knee arthroplasty (TKA) provided better pain relief than analgesic drugs alone. A pretest, posttest, randomized controlled trial study design with crossover was used to evaluate the effects of cryotherapy on postoperative pain and satisfaction with pain management. A convenience sample of postoperative knee replacement patients constituted participants in the study. Two sequential episodes of pain requiring analgesic administration were studied in each patient, one with a 30-minute cryotherapy application and the other without cryotherapy. Dependent variables were changes in pain (posttest minus pretest) and level of satisfaction with pain management. Data were analyzed with repeated-measures analysis of variance, with p < .05 considered significant. During two sequential treatments for postoperative pain, a total of 29 TKA patients received analgesic medication administration alone for one pain episode and analgesic medication administration with a brief cryotherapy administration for the other pain episode. No significant difference between the two treatments was found for changes in pain scores after the treatments or patient satisfaction with pain management (p > .05). The order in which the treatments were provided was found to be significant (p = .02) for scores on patient satisfaction with pain management, with cryotherapy as the treatment for the second pain episode having higher scores than when delivered for the first pain episode. Sixty minutes after analgesic administration with or without cryotherapy, average pain scores remained greater than 7. In TKA patients, the short-term application of cryotherapy with analgesic medication administration did not significantly decrease pain or improve patient satisfaction with pain management compared with analgesic medication administration only. Further study is necessary to determine whether short-term cryotherapy shortly after TKA is of benefit to pain relief and patient satisfaction.

Integrative therapies such as massage have gained support as interventions that improve the overall patient experience during hospitalization. Cardiac surgery patients undergo long procedures and commonly have postoperative back and shoulder pain, anxiety, and tension. Given the promising effects of massage therapy for alleviation of pain, tension, and anxiety, we studied the efficacy and feasibility of massage therapy delivered in the postoperative cardiovascular surgery setting. Patients were randomized to receive a massage or to have quiet relaxation time (control). In total, 113 patients completed the study (massage, n=62; control, n=51). Patients receiving massage therapy had significantly decreased pain, anxiety, and tension. Patients were highly satisfied with the intervention, and no major barriers to implementing massage therapy were identified. Massage therapy may be an important component of the healing experience for patients after cardiovascular surgery. Copyright 2009 Elsevier Ltd. All rights reserved.

This safety and feasibility study used autologous adipose-derived stromal vascular cells (the stromal vascular fraction [SVF] of adipose tissue), to treat 8 osteoarthritic knees in 6 patients of grade I to III (K-L scale) with initial pain of 4 or greater on a 10-point Visual Analog Scale (VAS). The primary objective of the study was evaluation of the safety of intra-articular injection of SVF. The secondary objective was to assess initial feasibility for reduction of pain in osteoarthritic knees. Adipose-derived SVF cells were obtained through enzymatic disaggregation of lipoaspirate, resuspension in 3 mL of Lactated Ringer's Solution, and injection directly into the intra-articular space of the knee, with a mean of 14.1 million viable, nucleated SVF cells per knee. Metrics included monitoring of adverse events and preoperative to postoperative changes in the Western Ontario and McMaster Universities Arthritis Index (WOMAC), the VAS pain scale, range of motion (ROM), timed up-and-go (TUG), and MRI. No infections, acute pain flares, or other adverse events were reported. At 3-months postoperative, there was a statistically significant improvement in WOMAC and VAS scores (P < .02 and P < .001, respectively), which was maintained at 1 year. Physical therapy measurements for ROM and TUG both improved from preoperative to 3-months postoperative. Standard MRI assessment from preoperative to 3-months postoperative showed no detectable structural differences. All patients attained full activity with decreased knee pain. Autologous SVF was shown to be safe and to present a new potential therapy for reduction of pain for osteoarthritis of the knee.

The purpose of this study was to compare postoperative rehabilitation with structured physiotherapy to the standard approach in patients with cervical radiculopathy (CR) in a prospective randomized study at 6 months follow-up based on measures of neck-related physical function, self-efficacy, and coping strategies. Patients with persistent CR and scheduled for surgery (N = 202) were randomly assigned to structured postoperative physiotherapy or a standard postoperative approach. Structured postoperative physiotherapy combined neck-specific exercises with a behavioral approach. Baseline, 3-month, and 6-month evaluations included questionnaires and clinical examinations. Neck muscle endurance, active cervical range of motion, self-efficacy, pain catastrophizing (CSQ-CAT), perceived control over pain, and ability to decrease pain were analyzed for between-group differences using complete case and per-protocol approaches. No between-group difference was reported at the 6-month follow-up (P = .05-.99), but all outcomes had improved from baseline (P < .001). Patients undergoing structured postoperative physiotherapy with ≥50% attendance at treatment sessions had larger improvements in CSQ-CAT (P = .04) during the rehabilitation period from 3 to 6 months after surgery compared with the patients who received standard postoperative approach. No between-group difference was found at 6 months after surgery based on measures of neck-related physical function, self-efficacy, and coping strategies. However, the results confirm that neck-specific exercises are tolerated by patients with CR after surgery and may suggest a benefit from combining surgery with structured postoperative physiotherapy for patients with CR.

To understand parents' experiences of managing their child's postoperative pain at home. Recent changes in children's health care services often shift the responsibility of managing children's postoperative pain to parents. Although pain management is important for good postoperative outcomes, it can be a challenging task for families, and children's pain is often under-managed. This qualitative study used semi-structured interviews to explore parents' experiences of managing their child's postoperative pain at home. Participants were parents of 10 typically developing 5- and 6-year olds, who underwent (adeno)tonsillectomy, and experienced no complications leading to hospitalisation in the postoperative period. One-on-one interviews were conducted with parents within three months of their child's surgery. Interviews were transcribed verbatim and content analysis was used to identify themes in parents' experiences. All children experienced some postoperative pain. Parents' experiences of managing their child's pain were impacted by balancing the pros and cons of administering analgesic medications, managing the emotional and psychological effects of their child's pain, as well as parents' information needs. Most parents' information needs were met yet they still struggled to manage their child's pain. These findings provide insight into some of the barriers that make this process challenging for many families, and what health care centres can do to help support parents manage their child's postoperative pain at home. The results of this study may aid in the design of interventions that will support parents when managing their child's postoperative pain at home and thus improve children's experiences. © 2016 John Wiley & Sons Ltd.

2017-01-01

Introduction Endodontic treatment performed in either single- or multiple visit can be followed by numerous short- and long term complications. One of the short term complications include postoperative pain and flare–ups. The ability to predict its prevalence and forewarn the patient may go some way towards enabling coping strategies and help dentist in pain management treatment decisions Aim To compare the incidence and intensity of postoperative pain and flare-ups between single- and multiple visit pulpectomy in primary molars. Also, to correlate the preoperative status of the pulp to postoperative pain and flare-ups. Materials and Methods Eighty primary molars indicated for pulpectomy were included in the study and divided into two groups. Tooth treated and preoperative status of the pulp vitality was recorded. All the conventional steps in pulpectomy were followed. Teeth in Group 1 (single visit pulpectomy) were obturated on the same visit. Teeth in Group 2 (multiple visit pulpectomy) were obturated in the subsequent appointment. The recording of postoperative pain, flare-ups, use of medication were done after 24 hours, seven days and one month. Results Four cases in both the groups reported postoperative pain (10%) at 24 hour recall, p=0.74. One flare-up (2.5%) was recorded in each group p=0.67. None of the patients reported pain at seventh day and one month recall. Postoperative pain was recorded in five non-vital teeth (13.5%) and three vital teeth (6.9%). However, it was statistically not significant p=0.53. Conclusion From the perspective of our study there was a low incidence of postoperative pain. The majority of patients in both groups reported no pain or only minimal pain within 24 hours of treatment. There were no differences between single- and multi visit treatment protocols with respect to the incidence of postoperative pain. No significant correlation could be found between pulp vitality and the incidence of postoperative pain. PMID:28511499

Although intravenous acetaminophen has been administered to reduce postoperative pain, it has not been used during cardiac implantable electronic devices (CIEDs) implantation. This was a randomized double-blinded interventional study. Thirty-two patients who were referred for new CIED implantation during July 2012 until April 2013 randomly received placebo or 1 g of intravenous acetaminophen. All patients were treated with local anesthesia. Pain score during incision, pocket creation, and in the recovery room, and the patients' need for analgesics during the 6 hours after the procedure were recorded in both groups. Seventeen and 15 patients received acetaminophen and placebo, respectively. Pain scores in patients treated with acetaminophen were significantly lower (4.4 vs 2.9, P = .004), and they received less analgesics (17% vs 60%, P = .014). Intravenous administration of acetaminophen is effective for pain relief in patients undergoing CIED implantation and decreases the need for postoperative analgesics.

The effects of pre-emptive infusion of ketamine-lidocaine with tramadol on the suppression of central sensitization were investigated in a dog ovariohysterectomy model. Twelve dogs were randomly assigned to two groups: ketamine-lidocaine-tramadol (KLT) and tramadol (T) groups. Both groups received intravenous tramadol 4 mg/kg body weight as premedication. Immediately after induction, the KLT group received ketamine and lidocaine at 0.5 and 2 mg/kg loading dose, followed by continuous rate infusion of 50 and 100 µg/kg/min, respectively, for 2 hours. Dogs in T group received saline bolus and continuous rate infusion at equi-volume. Intraoperatively, hemodynamic responses to surgical stimulation were recorded, whereas postoperative pain was evaluated using an algometer and short form of the Glasgow composite measure pain scale. Intraoperatively, hemodynamic responses to surgical stimulation were obtunded to a greater degree in KLT compared to T group. Postoperatively, the pain scores increased only for the first hour in KLT group, compared to 12 hours in T group. Mechanical thresholds at the abdomen decreased postoperatively between 12 and 60 hours in KLT group versus the entire 72 hours in T group. Thresholds at tibia and radius in both groups increased in the immediate 1 hour postoperatively, but decreased thereafter. Significant decrement of thresholds from baseline were detected in the tibia at 24, 42, and 60 hours in KLT group compared to 24-72 hours in T group, and in the radius between 36 and 48 hours in T group, but none in KLT group. Addition of pre-emptive ketamine-lidocaine infusion to single intravenous dose of tramadol enhanced attenuation of central sensitization and improved intra- and postoperative analgesia.

Background Risk factors associated with postoperative pain intensity and duration, as well as consumption of analgesics after ophthalmic surgery are poorly understood. Methods A prospective study was conducted among adults (N=226) who underwent eye surgery at the University Hospital Split, Croatia. A day before the surgery, the patients filled out questionnaires assessing personality, anxiety, pain catastrophizing, sociodemographics and were given details about the procedure, anesthesia, and analgesia for each postoperative day. All scales were previously used for the Croatian population. The intensity of pain was measured using a numerical rating scale from 0 to 10, where 0 was no pain and 10 was the worst imaginable pain. The intensity of pain was measured before the surgery and then 1 hour, 3 hours, 6 hours, and 24 hours after surgery, and then once a day until discharge from the hospital. Univariate and multivariate analyses were performed. Results A multivariate analysis indicated that independent predictors of average pain intensity after the surgery were: absence of premedication before surgery, surgery in general anesthesia, higher pain intensity before surgery and pain catastrophizing level. Independent predictors of postoperative pain duration were intensity of pain before surgery, type of anesthesia, and self-assessment of health. Independent predictors of pain intensity ≥5 during the first 6 hours after the procedure were the type of procedure, self-assessment of health, premedication, and the level of pain catastrophizing. Conclusion Awareness about independent predictors associated with average postoperative pain intensity, postoperative pain duration, and occurrence of intensive pain after surgery may help health workers to improve postoperative pain management in ophthalmic surgery.

The purpose of this study was to test the effect of the surgical removal of impacted mandibular third molars using piezosurgery versus the conventional surgical technique on postoperative sequelae and bone healing. Material and Methods. This study was carried out as a randomized controlled clinical trial: split mouth design. Twenty patients with bilateral mandibular third molar mesioangular impaction class II position B indicated for surgical extraction were treated randomly using either the piezosurgery or the conventional bur technique on each site. Duration of the procedure, postoperative edema, trismus, pain, healing, and bone density and quantity were evaluated up to 6 months postoperatively. Results. Test and control sites were compared using paired t-test. There was statistical significance in reduction of pain and swelling in test sites, where the time of the procedure was statistically increased in test site. For bone quantity and quality, statistical difference was found where test site showed better results. Conclusion. Piezosurgery technique improves quality of patient's life in form of decrease of postoperative pain, trismus, and swelling. Furthermore, it enhances bone quality within the extraction socket and bone quantity along the distal aspect of the mandibular second molar. PMID:27597866

A perioperative intravenous lidocaine infusion has been reported to decrease postoperative pain. The goal of this study was to evaluate the effectiveness of intravenous lidocaine in reducing postoperative pain for laparoscopic colectomy patients. Fifty-five patients scheduled for an elective laparoscopic colectomy were randomly assigned to 2 groups. Group L received an intravenous bolus injection of lidocaine 1.5 mg/kg before intubation, followed by 2 mg/kg/h continuous infusion during the operation. Group C received the same dosage of saline at the same time. Postoperative pain was assessed at 2, 4, 8, 12, 24, and 48 hours after surgery by using the visual analog scale (VAS). Fentanyl consumption by patient-controlled plus investigator-controlled rescue administration and the total number of button pushes were measured at 2, 4, 8, 12, 24, and 48 hours after surgery. In addition, C-reactive protein (CRP) levels were checked on the operation day and postoperative days 1, 2, 3, and 5. VAS scores were significantly lower in group L than group C until 24 hours after surgery. Fentanyl consumption was lower in group L than group C until 12 hours after surgery. Moreover, additional fentanyl injections and the total number of button pushes appeared to be lower in group L than group C (P < 0.05). The CRP level tended to be lower in group L than group C, especially on postoperative day1 and 2 and appeared to be statistically significant. The satisfaction score was higher in group L than group C (P = 0.024). Intravenous lidocaine infusion during an operation reduces pain after a laparoscopic colectomy. PMID:25785316

To evaluate multiple preoperative and operative factors that may be predictive of and correlate with acute postoperative pain levels after arthroscopic rotator cuff repair. One hundred eighty-one patients underwent arthroscopic rotator cuff surgery along with subacromial decompression and met the inclusion criteria for this study. Postoperative visual analog scale (VAS) scores were obtained on postoperative days 1, 7, and 90. Multivariate linear regression analysis was used to correlate postoperative VAS scores with multiple independent factors, including preoperative subjective pain tolerance, preoperative VAS score, preoperative narcotic use, sex, smoking status, number of suture anchors used, tear size, single- or double-row repair, and patient age. Preoperative subjective pain tolerance, notably those patients rating themselves as having an extremely high pain tolerance, was the most significant predictor of high VAS pain scores on both postoperative day 1 (P = .0001) and postoperative day 7 (P < .0001). Preoperative narcotic use was also significantly predictive (P = .010) of high pain scores on postoperative day 1 and day 7 (P = .019), along with nonsmokers (P = .008) and younger patients (P = .006) being predictive on day 7. There were no patient factors that were predictive of VAS scores 3 months postoperatively (P = .567). Preoperative subjective pain tolerance, notably those patients rating themselves as having an extremely high pain tolerance, was the strongest factor predicting high acute pain levels after arthroscopic rotator cuff surgery. Preoperative narcotic use, smokers, and younger patients were also predictive of higher pain levels during the first postoperative week. Level IV, prognostic case series.

To analyze the relationship between preoperative emotional state and the prevalence and intensity of postoperative pain and to explore predictors of postoperative pain. Observational retrospective study undertaken among 127 adult patients of orthopedic and trauma surgery. Postoperative pain was assessed with the verbal numeric scale and with five variables of emotional state: anxiety, sweating, stress, fear, and crying. The Chi-squared test, Student's t test or ANOVA and a multivariate logistic regression analysis were used for the statistical analysis. The prevalence of immediate postoperative pain was 28%. Anxiety was the most common emotional factor (72%) and a predictive risk factor for moderate to severe postoperative pain (OR: 4.60, 95% CI 1.38 to 15.3, p<0.05, AUC: 0.72, 95% CI: 0.62 to 0.83). Age exerted a protective effect (OR 0.96, 95% CI: 0.94-0.99, p<0.01). Preoperative anxiety and age are predictors of postoperative pain in patients undergoing orthopedic and trauma surgery.

Facial resurfacing with a CO 2 laser has been used for treatment of pathologic lesions and for cosmetic purposes. Postoperative complications and problems after laser resurfacing include infections, acneiform lesions, and pigment changes. This retrospective study describes the most common problems and complications in 105 patients and assesses postoperative pain in 38 patients. All patients received CO 2 laser resurfacing for treatment of malignant/premalignant lesions and had postoperative follow-up to assess problems and complications. Some had follow-up to assess postoperative pain. All patients had Fitzpatrick I-III skin types and underwent the same perioperative care regimen. There were 11 problems and 2 complications. Problems included infection, acneiform lesion/milia, and uncontrolled postoperative pain. Complications included hyperpigmentation. Among the postoperative pain group, 53% reported no pain and the rest had mild or moderate pain. Complications are rare. Infection and acneiform lesions/milia were the most common problems, as previously reported. Most patients do not experience postoperative pain. Copyright © 2016 Elsevier Inc. All rights reserved.

To assess the efficacy of intercostal nerve protection by intercostal muscle (ICM) flap in post-thoracotomy pain improvement compared to intracostal suturing. In a randomized controlled trial, ninety-four patients undergoing posterolateral thoracotomy surgery were divided into two subgroups. Intracostal sutures in isolation and in combination with ICM flap techniques were used for thoracotomy closure in both groups. Numeric Pain Scale and Visual Pain Scale as pain scores were assessed on the first, second, third, fourth, fifth, sixth and seventh postoperative days and follow-up visits during the 2 nd week, 1 st , 2 nd , 4 th and 6 th months after thoracotomy. Out of 94 patients, 58 were male and 36 were females. While the mean age of patients in intracostal group was 45.3 ± 17.6 years, it was 47.4 ± 16.1 years in intracostal plus ICM flap group. The mean operation time for the first group was 191.0 ± 74.7 minutes, while it was 219.3 ± 68.8 minutes in the second (p>0.05). Numeric rating score and visual pain scale did not demonstrate any significant difference in pain severity on postoperative days and follow-up visits between both groups (p>0.05). Although the trend of pain reduction was significant in each group (p<0.001), the difference was not statistically significant (p>0.001). Intracostal sutures in combination with muscle flap did not reduce postoperative pain in thoracotomy compared with intracostal sutures alone in thoracotomy closure.

Tonsillectomy in pediatric patients may cause severe postoperative pain. Topical local anesthetics are an easy and safe way to control post-tonsillectomy pain, but there is no benefit during the early postoperative stage. Topical ketamine shows a good effect on early stage postoperative pain. We compared the effect of topical ropivacaine with and without ketamine on post-tonsillectomy pain. Patients aged 3-7 years undergoing tonsillectomy were selected to participate in the study. Our study was performed in a randomized, placebo-controlled, double-blind manner. Patients were randomly assigned to one of two groups using computer-generated random numbers. The researchers who assessed the pain score, the caregivers, and the patient were blinded to group assignment. One group received topical ropivacaine with saline (RS group) and the other group received topical ropivacaine with 20 mg ketamine (RK group) on the tonsillar bed. Pain scores using the modified Children's Hospital of Eastern Ontario Pain Scale (mCHEOPS) at 15 min and 30 min, and at 1, 2, 4, 8, 16 and 24 h were recorded. Rescue analgesic requirement and complications were also recorded. A total of 66 patients were randomly assigned to the RS group (n = 33) and the RK group (n = 33). The mCHEOPS scores were significantly lower in the RK group at 15 min (P = 0.046). The mCHEOPS scores of the two groups decreased with time, but there was no intergroup interaction. The RS group received more analgesics until 1 h after surgery and the RK group received more analgesics during 1-24 h after surgery. There were no differences in adverse outcomes. Topical ropivacaine with ketamine can reduce immediate postoperative pain and analgesic requirement better than ropivacaine alone.

To determine postoperative pain in different types of ear, nose, and throat (ENT) surgery and their psychological preoperative predictors. Prospective cohort study. Academic hospital. A total of 217 patients undergoing ENT surgery. All ENT, neck, and salivary gland surgery. Postoperative pain and predictors for postoperative pain. Fifty percent of the patients undergoing surgery on the oral, pharyngeal, and laryngeal region and on the neck and salivary gland region had a visual analog scale score higher than 40 mm on day 1. In the patients who underwent oropharyngeal region operations the VAS score remained high on all 4 days. A VAS pain score higher than 40 mm was found in less than 30% of patients after endoscopic procedures and less than 20% after ear and nose surgery. After bivariate analysis, 6 variables--age, sex, preoperative pain, expected pain, short-term fear, and pain catastrophizing--had a predictive value. Multivariate analysis showed only preoperative pain, pain catastrophizing, and anatomical site of operation as independent predictors. Differences exist in the prevalence of unacceptable postoperative pain between ENT operations performed on different anatomical sites. A limited set of variables can be used to predict the occurrence of unacceptable postoperative pain after ENT surgery.

Ketamine and nefopam has been documented to decrease pain intensity and improve rehabilitation after total knee arthroplasty (TKA). We conducted a follow-up study of a previously randomized clinical trial to determine the prevalence and risk factors of chronic pain 1 year after TKA and to assess the role of perioperative administration of ketamine and nefopam. The original randomized, double-blind trial evaluated postoperative pain in 75 patients scheduled for TKA who received either a 48-hour infusion of ketamine or nefopam compared with placebo. The current study has evaluated patients at 6 and 12 months for the presence of chronic pain defined as a visual analogue scale ≥40 mm during a stair-climbing test. Other outcomes were incidence of neuropathic pain evaluated (DN4 score), active flexion of the knee, and functional outcome (KOOS-PS score). A total of 69 patients completed the trial. The prevalence of chronic pain at 12 months was 17.4% (95% confidence interval [CI], 10.2%-27.9%) without difference between the ketamine (12.5%), nefopam (13.7%), and placebo groups (26.1%). Prevalence of neuropathic pain was 10.2% (95% CI, 3%-17.3%). Ketamine reduced DN4 scores (P=0.02), increased knee flexion (P=0.0007), and KOOS-PS scores (P<0.0001) compared with placebo. A visual analogue scale score ≥60 mm in the postoperative period was the only risk factor associated with the occurrence of chronic pain (odds ratio 4.54; 95% CI, 1.17-17.67). After TKA, the intensity of postoperative pain is a risk factor of chronic pain on movement. Intraoperative ketamine seems to improve long-term results of rehabilitation in this setting.

Background Although circumcision for phimosis in children is a minor surgical procedure, it is followed by pain and carries the risk of increased postoperative anxiety. This study examined predictive factors of postoperative pain and anxiety in children undergoing circumcision. Methods We conducted a prospective cohort study of children scheduled for elective circumcision. Circumcision was performed applying one of the following surgical techniques: sutureless prepuceplasty (SP), preputial plasty technique (PP), and conventional circumcision (CC). Demographics and base-line clinical characteristics were collected, and assessment of the level of preoperative anxiety was performed. Subsequently, a statistical model was designed in order to examine predictive factors of postoperative pain and postoperative anxiety. Assessment of postoperative pain was performed using the Faces Pain Scale (FPS). The Post Hospitalization Behavior Questionnaire study was used to assess negative behavioral manifestations. Results A total of 301 children with a mean age of 7.56 ± 2.61 years were included in the study. Predictive factors of postoperative pain measured with the FPS included a) the type of surgical technique, b) the absence of siblings, and c) the presence of postoperative complications. Predictive factors of postoperative anxiety included a) the type of surgical technique, b) the level of education of mothers, c) the presence of preoperative anxiety, and d) a history of previous surgery. Conclusions Although our study was not without its limitations, it expands current knowledge by adding new predictive factors of postoperative pain and postoperative anxiety. Clearly, further randomized controlled studies are needed to confirm its results. PMID:26495079

A growing multibillion dollar industry markets magnetic necklaces, bracelets, bands, insoles, back braces, mattresses, etc., for pain relief, although there is little evidence for their efficacy. We sought to evaluate the effect of magnetic therapy on pain intensity and opioid requirements in patients with postoperative pain. We designed a randomized, double-blind, controlled trial. One-hundred-sixty-five patients older than 12 yr of age were randomized to magnetic (n = 81) or sham therapy (n = 84) upon reporting moderate-to-severe pain in the postanesthesia care unit. Devices were placed over the surgical incision and left in place for 2 h. Patients rated their pain intensity on a 0-10 scale every 10 min and received incremental doses of morphine until pain intensity was < or =4 of 10. Pain intensity levels were similar in both groups. The magnet group had on average 0.04 U more pain intensity (95% confidence interval, -0.4 to 0.5) than the sham group. Opioid requirements also were similar in both groups. The active magnet group required 1.5 mg more morphine (95% confidence interval, -1.8 to 4.0) than the sham magnet group. Magnetic therapy lacks efficacy in controlling acute postoperative pain intensity levels or opioid requirements and should not be recommended for pain relief in this setting.

Dexmedetomidine (DEX) is an alpha 2-adrenoreceptor agonist, which induces sedation and analgesia. This study aimed to determine whether intranasal DEX offered perioperative sedation and better postoperative analgesia. Patients having unilateral third molar surgery under local anaesthesia were recruited and allocated to receive either intranasal DEX 1 µg kg(-1) (Group D) or same volume of saline (Group P) 45 min before surgery. Patient-controlled sedation with propofol was offered as a rescue sedative. Perioperative sedation, postoperative pain relief and analgesic consumption, vital signs, adverse events, postoperative recovery, and satisfaction in sedation and analgesia were assessed. Thirty patients from each group were studied. Areas under curve (AUC) of postoperative numerical rating scale (NRS) pain scores 1-12 h at rest and during mouth opening were significantly lower in Group D (P=0.003 and 0.009, respectively). AUC BIS values and OAA/S sedation scores were significantly lower before surgery and at the recovery area (all P<0.01) with significantly less intra-operative propofol used in group D (P<0.01). In group D, heart rate was significantly lower at recovery period (P=0.005) while systolic blood pressure in different periods of the study (all P<0.01), but the decreases did not require treatment. More patients from placebo group experienced dizziness (P=0.026) but no serious adverse event was found. No difference was found in postoperative psychomotor recovery and satisfaction in pain relief and sedation. Patients receiving intranasal DEX for unilateral third molar surgery with local anaesthesia were more sedated perioperatively with better postoperative pain relief. No delay in psychomotor recovery was seen.

Inguinal disruption, a common condition in athletes, is a diagnostic and therapeutic challenge. The aim of this study was to evaluate the effect of endoscopic totally extraperitoneal (TEP) repair in athletes with inguinal disruption, selected through a multidisciplinary, systematic work-up. An observational, prospective cohort study was conducted in 32 athletes with inguinal disruption. Athletes were assessed by a sports medicine physician, radiologist and hernia surgeon and underwent subsequent endoscopic TEP repair with placement of polypropylene mesh. The primary outcome was pain reduction during exercise on the numeric rating scale (NRS) 3 months postoperatively. Secondary outcomes were sports resumption, physical functioning and long-term pain intensity. Patients were assessed preoperatively, 3 months postoperatively and after a median follow-up of 19 months. Follow-up was completed in 30 patients (94%). The median pain score decreased from 8 [interquartile range (IQR) 7-8] preoperatively to 2 (IQR 0-5) 3 months postoperatively (p < 0.001). At long-term follow-up, the median pain score was 0 (IQR 0-3) (p < 0.001). At 3 months, 60% of patients were able to complete a full training and match. The median intensity of sport was 50% (IQR 20-70) preoperatively, 95% (IQR 70-100) 3 months postoperatively (p < 0.001), and 100% (IQR 90-100) at long-term follow-up (p < 0.001). The median frequency of sport was 4 (IQR 3-5) times per week before development of symptoms and 3 (IQR 3-4) times per week 3 months postoperatively (p = 0.025). Three months postoperatively, improvement was shown on all physical functioning subscales. Athletes with inguinal disruption, selected through a multidisciplinary, systematic work-up, benefit from TEP repair.

Abstract Background: Trial design neuroinflammation and postoperative pain after surgery are increasingly reported in association with postoperative cognitive dysfunction (POCD). Parecoxib, a selective cyclooxygenase (COX)-2 inhibitor, is used for postoperative analgesia for its potent anti-inflammatory and analgesic effects. This study aimed to evaluate parecoxib's effects on POCD in elderly patients undergoing total knee arthroplasty. Methods: Around 134 elderly patients undergoing total knee arthroplasty were randomly divided into parecoxib (group P) and control (group C) groups, and treated with parecoxib sodium and saline, respectively, shortly after induction of general anesthesia and 12-h postsurgery, respectively. Perioperative plasma IL-1β, IL-6, TNF-α, and C-reactive protein (CRP) 1evels were measured. Postoperative pain was assessed following surgery. Neuropsychological tests were performed before surgery, and 1 week and 3 months postoperation. Results: POCD incidence in group P was significantly lower compared with that of group C at 1 week after surgery (16.7% vs 33.9%; P < 0.05); no significant difference was found between groups C and P at 3-month follow-up (9.7% vs 6.7%). Compared with group C values, visual analog pain scale (VAS) scores at 3, 6, and 12 hours after surgery were significantly lower in group P(P < 0.05). Plasma IL-1β, IL-6, and TNF-α levels were lower in group P than in group C after the operation (P < 0.05). No significant difference in the plasma CRP level was found between groups P and C. Conclusions: Parecoxib sodium decreases POCD incidence after total knee arthroplasty in elderly patients and may explain how this drug suppresses inflammation and acute postoperative pain caused by surgical trauma.

The authors hypothesized that intravenous acetaminophen as an adjunct analgesic would significantly decrease 24-hour postoperative opioid consumption. Double-blind, randomized, placebo-controlled trial. A single academic medical center. The study was comprised of 68 adult patients undergoing cardiac surgery. Patients were assigned randomly to receive either 1,000 mg of intravenous acetaminophen or placebo immediately after anesthesia induction, at the end of surgery, and then every 6 hours for the first 24 hours in the intensive care unit, for a total of 6-1,000 mg doses. The primary outcome was 24-hour postoperative opioid consumption. The secondary outcomes included 48-hour postoperative opioid consumption, incisional pain scores, opioid-related adverse effects, length of mechanical ventilation, length of intensive care unit stay, and the extent of wound hyperalgesia assessed at 24 and 48 hours postoperatively. The mean±standard deviation postoperative 24-hour opioid consumption expressed in morphine equivalents was significantly less in the acetaminophen group (45.6±29.5 mg) than in the placebo group (62.3±29.5 mg), representing a 27% reduction in opioid consumption (95% CI, 2.3-31.1 mg; p = 0.024). There were no differences in pain scores and opioid-related adverse effects between the 2 groups. A significantly greater number of patients in the acetaminophen group responded "very much" and "extremely well" when asked how their overall pain experience met their expectation (p = 0.038). The administration of intravenous acetaminophen during cardiac surgery and for the first 24 hours postoperatively reduced opioid consumption and improved patient satisfaction with their overall pain experience but did not reduce opioid side effects.

Study Objective To evaluate if the administration of intraperitoneal bupivacaine decreased postoperative pain in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery. Design Retrospective cohort study (Canadian Task Force classification II-3). Setting University-based gynecologic oncology practice operating at a tertiary medical center. Patients All patients on the gynecologic oncology service undergoing minimally invasive surgery between September 2011 and June 2013. Interventions Starting August 2012, intraperitoneal administration of .25% bupivacaine was added to all minimally invasive surgeries. These patients were compared with historical control subjects who had surgery between September 2011 and July 2012 but did not receive intraperitoneal bupivacaine. Measurements and Main Results One-hundred thirty patients were included in the study. The patients who received intraperitoneal bupivacaine had lower median narcotic use on the day of surgery and the first postoperative day compared with those who did not receive intraperitoneal bupivacaine (day 0: 7.0 mg morphine equivalents vs 11.0 mg, p = .007; day 1: .3 mg vs 1.7 mg, p = .0002). The median patient-reported pain scores were lower on the day of surgery in the intraperitoneal bupivacaine group (2.7 vs 3.2, p = .05) Conclusions The administration of intraperitoneal bupivacaine was associated with improved postoperative pain control in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery and should be further evaluated in a prospective study.

To enhance understanding of the experience of parents in managing their children's postoperative pain in Singapore. Parents play a significant role in their hospitalised child's postoperative pain care. Their active involvement may contribute to accurate pain assessment and effective pain management for their child. However, there is a lack of in-depth research exploring the experience of parents involved in their children's postoperative pain management. This study adopted a descriptive qualitative approach, which is situated in the interpretive paradigm. Semi-structured interviews were conducted to collect data from 14 parents whose children were hospitalised in one of the three paediatric surgical wards in a hospital in Singapore in December 2009. Thematic analysis was used to analyse the data. Three themes were identified: 'Actions used by parents to alleviate their child's postoperative pain', 'Factors influencing parents' management of their child's postoperative pain' and 'Parents' needs in the process of caring for their child's postoperative pain'. Parents used a range of non-pharmacological pain relief interventions for their child. Parental roles and expectations, bond between parent and child, support from nurses, family and own religious beliefs, as well as children's age and maturity level were factors which promoted parental participation, whereas parents' negative feelings, knowledge deficit and nurses' busy schedule were hindering factors. Parents expressed needs for more involvement in their child's care, adequate rest and information support from nurses. This study highlights the importance of involving parents in their child's postoperative pain management. It provides evidence for health care professionals to pay attention to factors that may influence parental participation and, therefore, guide their practice. Nurses need to provide parents with support and education to facilitate their roles and improve their child's postoperative pain management. © 2011 Blackwell Publishing Ltd.

Postlaparoscopic shoulder pain (PLSP) remains a common problem after laparoscopies. The aim of this study was to investigate the correlation between pressure pain threshold (PPT) of different muscles and PLSP after gynecologic laparoscopy, and to explore the effect of parecoxib, a cyclooxygenase-2 inhibitor, on the changes of PPT. The patients were randomly allocated into two groups; group P and group C. In group P, parecoxib 40 mg was intravenously infused at 30 minutes before surgery and 8 and 20 hours after surgery. In group C, normal saline was infused at the corresponding time point. PPT assessment was performed 1 day before surgery and at postoperative 24 hours by using a pressure algometer at bilateral shoulder muscles (levator scapulae and supraspinatus) and forearm (flexor carpi ulnaris). Meanwhile, bilateral shoulder pain was evaluated through visual analog scale score at 24 hours after surgery. Preoperative PPT level of the shoulder, but not of the forearm, was significantly and negatively correlated with the intensity of ipsilateral PLSP. In group C, PPT levels of shoulder muscles, but not of forearm muscles, decreased after laparoscopy at postoperative 24 hours. The use of parecoxib significantly improved the decline of PPT levels of bilateral shoulder muscles (all P <0.01). Meanwhile, parecoxib reduced the incidence of PLSP (group P: 45% vs group C: 83.3%; odds ratio: 0.164; 95% confidence interval: 0.07-0.382; P <0.001) and the intensity of bilateral shoulder pain (both P <0.01). Preoperative PPT levels of shoulder muscles are closely associated with the severity of shoulder pain after gynecologic laparoscopy. PPT levels of shoulder muscles, but not of forearm muscles, significantly decreased after surgery. Parecoxib improved the decrease of PPT and relieved PLSP.

Effective use of postoperative incentive spirometry improves patient outcomes but is limited by pain after thoracic and upper abdominal surgery. Thoracic epidurals are frequently used to provide analgesia and attenuate postoperative pulmonary dysfunction. We hypothesized that, in patients with thoracic epidurals for thoracic and abdominal surgery, high pain scores would be associated with poorer incentive spirometry performance, even when accounting for other variables. Retrospective study of 468 patients who underwent upper abdominal or thoracic surgery using postoperative thoracic epidural analgesia between June 1, 2009, and August 31, 2013, at a single tertiary academic center. The association between incentive spirometry performance and pain was assessed as the primary outcome. Other independent predictors of incentive spirometry performance were also identified. Postoperative incentive spirometry performance was found to be inversely proportional to pain score, which correlated significantly stronger with deep breathing pain compared with pain at rest (-0.33 vs -0.14 on postoperative day 1; -0.23 vs -0.12 on postoperative day 2). Pain with deep breathing was independently associated with poorer incentive spirometry performance in the multivariable linear regression model (P < 0.0001), as was increasing age, female sex, thoracic surgery, and higher American Society of Anesthesiologists (ASA) physical status score. The present study suggests that pain with deep breathing is more indicative of thoracic epidural efficacy than is pain at rest. Furthermore, incentive spirometry performance could be used as another indicator of thoracic epidural efficacy. This may be particularly useful in patients reporting high pain scores postoperatively.

Multimodal analgesic strategies are recommended to decrease opioid requirements and opioid-induced respiratory complications in patients undergoing laparoscopic bariatric surgery. Recent studies have demonstrated that intravenous ibuprofen decreases opioid consumption compared with placebo. The primary aim of this study was to compare the effect of intravenous ibuprofen and intravenous acetaminophen on opioid consumption. We also aimed to compare postoperative pain levels and side effects of the drugs. Randomized, double-blinded study. University hospital. Eighty patients, aged 18-65 years, (ASA physical status II-III) undergoing laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass surgery were included in this study. Patients were randomized to receive 800 mg ibuprofen or 1 g acetaminophen intravenously every 6 h for the first 24 h following surgery; in addition, patient-controlled analgesia with morphine was administered. Postoperative morphine consumption in the first 24 h, visual analog scale (VAS) pain scores at rest and with movement, and opioid related side effects were assessed. In addition, time to passage of flatus, surgical complications, lengths of intensive care unit and hospital stay, and laboratory parameters were recorded. The mean morphine consumption was 23.94 ± 13.89 mg in iv ibuprofen group and 30.23 ± 13.76 mg in the acetaminophen group [mean difference: -6.28 (95% CI, -12.70, 0.12); P = 0.055]. The use of intravenous ibuprofen was associated with reduction in pain at rest (AUC, 1- to 24-h, P < 0.001 and 12- to 24-h, P = 0.021) and pain with movement (AUC, 1-24, 6-24, and 12-24 h, P < 0.001). Intravenous ibuprofen was well tolerated with no serious side effects except dizziness. Intravenous ibuprofen did not significantly reduce opioid consumption compared to intravenous acetaminophen; however, it reduced the severity of pain. Intravenous ibuprofen may be a good alternative to intravenous acetaminophen as part of a multimodal postoperative analgesia in patients undergoing bariatric surgery. Copyright © 2018.

One of the advantages of laparoscopic bariatric surgery is the reduced level of postoperative pain. In some cases, however, the pain level may be high. This is a challenge for specialists. This case study explores the use of VR distraction in an 18 year-old patient who had undergone laparoscopic bariatric surgery and who reported pain during the postoperative period. The study was conducted in a Level III Private Hospital in Mexico City where the patient was hospitalized. The patient was administered standard analgesic during VR distraction, which lasted a total of 40 minutes divided into two sessions. The scores of three visual analogue scales and catastrophism were the dependent variables of this study. The scales were administered before and after the VR distraction intervention. The patient reported lower pain levels after VR distraction and reductions in some components of catastrophism. This study proves that VR distraction can be effective not only in reducing the physical component of pain (a notion that is already well established) but also the cognitive/affective component. More controlled studies of the issue are required.

Effect of Music Therapy on Postoperative Pain Management in Gynecological Patients: A Literature Review.

Unrelieved postoperative pain may have a negative impact on the physiological and psychological well-being of patients. Pharmacological methods are currently used to relieve such pain in gynecological patients; however, inadequate pain control is still reported, and the use of nonpharmacological pain-relieving methods is increasingly being advocated, one of which is music therapy. The purpose of this literature review was to identify, summarize, and critically appraise current evidence on music therapy and postoperative pain management among gynecological patients. A systematic search of MEDLINE, CINAHL, PsycINFO, British Nursing Index, and Allied and Complementary Medicine was conducted using the search terms music, gynecological, pain, surgery, operative, and post-operative to identify relevant articles in English from 1995 to the present. All identified articles were assessed independently for inclusion into review. A total of 7 articles were included after removal of duplicates and exclusion of irrelevant studies. All the included studies assessed the effects of music therapy on postoperative pain intensity, and three of them measured pain-related physiological symptoms. The findings indicated that music therapy, in general, was effective in reducing pain intensity, fatigue, anxiety, and analgesic consumption in gynecological patients during the postoperative period. It is recommended as an adjunct to pharmacological pain-relieving methods in reducing postoperative pain. Future researches on music therapy to identify the most effective application and evaluate its effect by qualitative study are recommended.

Accelerated recovery programs are clinical pathways which outline the stages, and streamline the means, and techniques aiming toward the desired end a rapid return of the patient to his pre-operative physical and psychological status. Recovery from colo-rectal surgery may be slowed by the patient's general health, surgical stress, post-surgical pain, and post-operative ileus. Both surgeons and anesthesiologists participate throughout the peri-operative period in a clinical pathway aimed at minimizing these delaying factors. Key elements of this pathway include avoidance of pre-operative colonic cleansing, early enteral feeding, and effective post-operative pain management permitting early ambulation (usually via thoracic epidural anesthesia). Pre-operative information and motivation of the patient is also a key to the success of this accelerated recovery program. Studies of such programs have shown decreased duration of post-operative ileus and hospital stay without an increase in complications or re-admissions. The elements of the clinical pathway must be regularly re-evaluated and updated according to local experience and published data.

2014-01-01

Measures of central pain processing like conditioned pain modulation (CPM), and suprathreshold heat pain response (SHPR) have been described to assess different components of central pain modulatory mechanisms. Central pain processing potentially play a role in the development of postsurgical pain, however, the role of CPM and SHPR in explaining postoperative clinical pain and disability is still unclear. Seventy eight patients with clinical shoulder pain were included in this study. Patients were examined before shoulder surgery, at 3 months, and 6 months after surgery. The primary outcome measures were pain intensity and upper extremity disability. Analyses revealed that the change score (baseline – 3 months) of 5th pain rating of SHPR accounted for a significant amount of variance in 6 month postsurgical clinical pain intensity and disability after age, sex, preoperative pain intensity, and relevant psychological factors were considered. The present study suggests that baseline measures of central pain processing were not predictive of 6 month postoperative pain outcome. Instead, the 3 month change in SHPR might be a relevant factor in the transition to elevated 6-month postoperative pain and disability outcomes. In patients with shoulder pain, the 3 month change in a measure of central pain processing might be a relevant factor in the transition to elevated 6-month postoperative pain and disability scores.

A number of trials have examined the peripheral analgesic effect of opioids, known to have an anti-nociceptive effect at the central and/or spinal cord level. This study aimed to evaluate the efficacy of buprenorphine added to 2% lignocaine with adrenaline 1:80,000 in providing postoperative analgesia after lower third molar surgery. Sixty patients were randomized to three groups: group A received lignocaine 2% with adrenaline 1:80,000 for inferior alveolar nerve block (IANB), along with intramuscular (IM) injection of 1ml saline; group B received buprenorphine mixed with lignocaine 2% with adrenaline 1:80,000 for IANB (0.01mg buprenorphine/ml lignocaine with adrenaline), along with 1ml saline IM; group C received lignocaine 2% with adrenaline 1:80,000 for IANB, along with 0.03mg buprenorphine IM. Mean postoperative pain scores (visual analogue scale; when the patient first felt pain) were 6.0 for group A, 1.0 for group B, and 4.4 for group C. The mean duration of postoperative analgesia was 3.5h in groups A and C and 12h in group B. The mean number of postoperative analgesics consumed was 5.8 in groups A and C and 3.9 in group B. The addition of buprenorphine (0.03mg) to 2% lignocaine with adrenaline 1:80,000 significantly reduced the severity of postoperative pain and prolonged the duration of analgesia, thereby decreasing the need for postoperative analgesics.

Clinical studies have been previously carried out on the efficacy of systemic magnesium to minimize postoperative pain, however, with controversial results. A quantitative meta-analysis was performed to evaluate the analgesic efficacy and safety of systemic magnesium on post-operative pain. Comprehensive systematic review of all relevant, publsished randomized controlled trials. A search was conducted of published literature in MEDLINE, PsycINFO, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception to Sep-Oct 2014. Randomized controlled trials (RCTs) that compared magnesium with placebo were identified. Effects were summarized using standardized mean differences (SMDs), weighed mean differences (WMD), or odds ratio (OR) with suitable effect model. Twenty-seven RCTs involving 1,504 patients were included. In total, peri-operative magnesium significantly reduced the pain score at rest (SMD, -1.43, 95% CI, -2.74 to -0.12, < 0.01). Magnesium significantly reduced analgesic consumption (SMD, -1.72, 95% CI, -3.21 to -0.23) in patients undergoing urogenital, orthopaedic, and cardiovascular surgeries, but was inconclusive for patients receiving gastrointestinal surgeries. The obvious analgesia of systemic magnesium was observed on reducing the pain score during movement at 24 hours after operation (SMD, -0.05, 95% CI, -0.43 to 0.32). Moreover, magnesium administration showed a beneficial effect with regard to intra-operative hemodynamics and reduced extubation time in the cardiovascular surgery patients (WMD, -29.34 min, 95% CI, -35.74 to -22.94, P < 0.01). Focused only on the quality of analgesia on postoperative pain with regards to surgery type. Our study suggests that systemic magnesium during general anesthesia significantly decreases post-operative pain scores without increasing adverse events. It should be noted that since there are 18 ongoing RCTs without published data, it is still premature to draw conclusions on the long-term analgesic effects of magnesium as well as potential gender or age difference.

Background Chronic pain is associated with depression. In rodents, pain is often assessed by sensory hypersensitivity, which does not sufficiently measure affective responses. Low-dose ketamine has been used to treat both pain and depression, but it is not clear whether ketamine can relieve depression associated with chronic pain and whether this antidepressant effect depends on its anti-nociceptive properties. Methods We examined whether the spared nerve injury (SNI) model of neuropathic pain induces depressive behavior in rats, using sucrose preference test and forced swim test, and tested whether a subanesthetic dose of ketamine treats SNI-induced depression. Results SNI-treated rats, compared with control, showed decreased sucrose preference (0.719 ± 0.068 (mean ± SEM) vs. 0.946 ± 0.010) and enhanced immobility in the forced swim test (107.3 ± 14.6s vs. 56.2 ± 12.5s). Further, sham-operated rats demonstrated depressive behaviors in the acute postoperative period (0.790 ± 0.062 on postoperative day 2). A single subanesthetic dose of ketamine (10mg/kg) did not alter SNI-induced hypersensitivity; however, it treated SNI-associated depression-like behaviors (0.896 ± 0.020 for ketamine vs. 0.663 ± 0.080 for control 1 day after administration; 0.858 ± 0.017 for ketamine vs. 0.683 ± 0.077 for control 5 days after administration). Conclusions Chronic neuropathic pain leads to depression-like behaviors. The postoperative period also confers vulnerability to depression, possibly due to acute pain. Sucrose preference test and forced swim test may be used to compliment sensory tests for assessment of pain in animal studies. Low-dose ketamine can treat depression-like behaviors induced by chronic neuropathic pain. PMID:21934410

Continuous-infusion local anesthetic pain pump use and seroma formation with abdominal procedures: is there a correlation?

Seroma formation is the most commonly occurring complication in plastic surgery abdominal procedures. Continuous local anesthetic pain pump delivery systems are often used to decrease postoperative pain. An unreported concern with use of these devices in abdominal procedures is the effect of continuous fluid infiltration of the surgical site and a possible increase in the incidence of seroma formation. The authors performed a retrospective chart review to evaluate all patients (n = 159) who underwent abdominal procedures (abdominoplasty, panniculectomy, and transverse rectus abdominis myocutaneous flap harvest) over a 3-year period. Patient charts were evaluated for sex, age, body mass index, procedure performed, surgeon, operation length, pain pump use, postoperative seroma formation, and any complications. In cases with pain pump use, catheter placement location, anesthetic medication and strength, continuous-infusion rate, and duration of pain pump use were also reviewed. If a postoperative seroma formation was identified, treatment and outcomes were also recorded. The overall seroma formation rate was 11.3 percent (18 of 159 patients). Other complications occurred at a rate of 2.5 percent (four of 159). The incidence of seroma was 11.0 percent (11 of 100) in patients with pain pump use versus 11.9 percent (7 of 59) in those who did not use a pain pump. There was no statistically significant difference (p = 0.9) in the incidence of seroma formation between those who did and did not use a pain pump device. There was no correlation between increased rate of seroma formation and use of a continuous-infusion local anesthetic pain pump system in our patient population.

Most patients who undergo surgical procedures experience acute postoperative pain, but evidence suggests that less than half report adequate postoperative pain relief. Many preoperative, intraoperative, and postoperative interventions and management strategies are available for reducing and managing postoperative pain. The American Pain Society, with input from the American Society of Anesthesiologists, commissioned an interdisciplinary expert panel to develop a clinical practice guideline to promote evidence-based, effective, and safer postoperative pain management in children and adults. The guideline was subsequently approved by the American Society for Regional Anesthesia. As part of the guideline development process, a systematic review was commissioned on various aspects related to various interventions and management strategies for postoperative pain. After a review of the evidence, the expert panel formulated recommendations that addressed various aspects of postoperative pain management, including preoperative education, perioperative pain management planning, use of different pharmacological and nonpharmacological modalities, organizational policies, and transition to outpatient care. The recommendations are based on the underlying premise that optimal management begins in the preoperative period with an assessment of the patient and development of a plan of care tailored to the individual and the surgical procedure involved. The panel found that evidence supports the use of multimodal regimens in many situations, although the exact components of effective multimodal care will vary depending on the patient, setting, and surgical procedure. Although these guidelines are based on a systematic review of the evidence on management of postoperative pain, the panel identified numerous research gaps. Of 32 recommendations, 4 were assessed as being supported by high-quality evidence, and 11 (in the areas of patient education and perioperative planning, patient assessment, organizational structures and policies, and transitioning to outpatient care) were made on the basis of low-quality evidence. This guideline, on the basis of a systematic review of the evidence on postoperative pain management, provides recommendations developed by a multidisciplinary expert panel. Safe and effective postoperative pain management should be on the basis of a plan of care tailored to the individual and the surgical procedure involved, and multimodal regimens are recommended in many situations.

The aim of this study was to evaluate the analgesic efficacy and safety of pectoralis-serratus interfascial plane block in comparison with thoracic paravertebral block for postmastectomy pain. A prospective randomized controlled study. Tertiary center, university hospital. Sixty-four adult women, American Society of Anesthesiologists physical status classes I, II, and III, scheduled for unilateral modified radical mastectomy with axillary evacuation. Patients were randomized to receive either pectoralis-serratus interfascial plane block, PS group (n=32), or thoracic paravertebral block, PV group (n=32). Twenty-four-hour morphine consumption and the time to rescue analgesic were recorded. The pain intensity evaluated by visual analog scale (VAS) score at 0, 2, 4, 8, 16, and 24hours postoperatively was also recorded. The median (interquartile range) postoperative 24-hour morphine consumption was significantly increased in PS group in comparison to PV group (PS vs PV), 20 mg (16-23 mg) vs 12 mg (10-14 mg) (P<.001). The median postoperative time to first analgesic request was significantly shorter in PS group compared to PV group (PS, 6 hours [5-7 hours], vs PV, 11 hours [9-13 hours]) (P<.001). The intensity of pain was low in both groups in VAS 0, 2, and 4hours postoperatively. However, there was significant reduction in VAS in PV group compared to PS group at 8, 16, and 24hours postoperatively. Pectoralis-serratus interfascial plane block was safe and easy to perform and decreased intensity of postmastectomy pain, but it was inferior to thoracic paravertebral block.

With current technological advancement and availability of synthetic materials used in inguinal hernia repair, a recurrence after first intervention is not a common and important adverse event. On the other hand, however, some patients complain about chronic pain of the operated site after surgeries using a polypropylene mesh. Many patients are constrained to a prolonged use of analgesics and increased frequency of control visits, which may eventually result in loss of trust in the operator. Every surgical intervention is associated with the risk of immediate or delayed complications. Genitofemoral neuralgia is associated with dysfunction of peripheral nerves passing through the inguinal canal or the surrounding tissue and it is a chronic, troublesome and undesired complication of an inguinal hernia repair. The possibility of minimizing chronic inguinal pain by proper management during herniorraphy should be considered in all cases of an inguinal canal reconstruction. The aim of the study was to investigate whether an intraoperative injection of 0.5% bupivacaine into the operated site (preemptive analgesia) has an influence on the postoperative pain assessed on the day of operation as well as the 1st and 2nd postoperative day after Lichtenstein hernioplasty of an inguinal, scrotal or recurrent hernia. In the studied population, we attempted to identify risk factors affecting pain level after surgical repair of an inguinal, scrotal or recurrent hernia. During the period between December 2015 and May 2016, 133 patients with preoperative diagnosis of an inguinal (81.95%, n=109), scrotal (13.53%, n=18) or recurrent hernia (4.51%, n=6) underwent an elective intervention and were randomly allocated to the group, which intraoperatively received 20 mL of 0.5% bupivacaine locally in selected anatomical points of the inguinal canal. In the group with preoperative diagnosis of an inguinal hernia, this intervention was applied in 56.88% of cases (n=62). In the case of scrotal or recurrent hernia, a similar intervention was applied in 41.67% (n=10) of patients. During the hospital stay, pain was assessed four times a day using the NRS numeric scale. All patients received preoperative antibiotic prophylaxis, and, during observation, analgesics and low-molecular-weight heparin were used. In the studied group, risk factor were identified, which affect the pain level associated with surgical treatment of an inguinal hernia. Mean pain level score according to the NRS scale (0-10) for an inguinal hernia was 4.17 on day 0 (standard deviation 2.22; minimum 0; maximum 10). On day 1 - 2.86 (standard deviation 1.86; minimum 0; maximum 8). On day 2 - 0.84 (standard deviation 1.21; minimum 0; maximum 5). The values of those parameters for a scrotal and recurrent hernia were as follows: on day 0 - 3.67 (standard deviation 1.76; minimum 0; maximum 7). On day 1 - 3.79 (standard deviation 1.67; minimum 0; maximum 7). On day 2 - 2.25 (standard deviation 1.54; minimum 0; maximum 4). Intraoperative application of 20 mL 0.5% bupivacaine did not reduce the postoperative pain on the postoperative day 0, 1, 2. Among independent risk factors exacerbating pain, the following variables were identified: local complications of the operated site including edema, ecchymosis and hematoma of the inguinal region. More frequent dressing changes were directly correlated with an increased pain sensation. Postoperative urethral catheterization due to urinary retention was associated with an increased pain immediately after surgery. In the case of intraoperative diagnosis of concurrent direct and indirect hernia (so-called pantaloon hernia), less intense pain was observed on postoperative day 0. Other parameters such as age, sex, duration of operation, duration of hospitalization and wound drainage did not influence the pain sensation. Local injection of an analgesic into the operated site was not associated with the reduction of pain assessed on postoperative day 0, 1 and 2 after an isolated inguinal, scrotal or recurrent hernia repair. Pathologies of the operated site such as edema, ecchymosis or hematoma were associated with an increased pain sensations on observation. Also, postoperative urinary retention and urethral catheterization increased the pain sensation after an inguinal hernia repair. A lack of wound complications significantly decreased the pain sensation during the immediate postoperative period after hernia repair.

Background We wanted to determine the postoperative analgesic efficacy of preincisional caudal epidural block versus instillation (splash block) following inguinal herniorrhaphy in children. Methods Thirty children (age range: 1-7 years) who were scheduled to undergo inguinal herniorrhaphy were divided into 2 groups: the caudal block group and the splash block group with 15 children in each group. Tracheal intubation was performed. Fifteen children received caudal block with 1.0 ml/kg of 0.25% ropivacaine (Group 1). Caudal block was performed using the loss of resistance method via the sacral hiatus. Fifteen children in Group 2 received local instillation (splash block) in the surgical site with up to 0.4 ml/kg of 0.25% ropivacaine. The patients were observed for 90 minutes in the postanesthesia care unit and then they were transferred to the ward. The pain scores were taken 4 times. We assessed pain using the Faces pain scores. Results There were no significant differences between the groups regarding the pain scores at 10, 30 and 60 minutes upon entering the postanesthesia care unit. The pain scores of Group 1 were slightly lower at the last evaluation point when compared to that of Group 2. One patient in Group 1 required supplemental postoperative intravenous (IV) tramadol, while all the other patients in both groups did not require supplemental IV tramadol. The intraoperative requirement for sevoflurane was decreased in Group 1 as compared to that of Group 2. There were no major complications related to either type of block. Conclusions We conclude that a splash block can have a similar analgesic effect as that of a caudal block for the postoperative herniorrhaphy pain of children. PMID:21602975

We wanted to determine the postoperative analgesic efficacy of preincisional caudal epidural block versus instillation (splash block) following inguinal herniorrhaphy in children. THIRTY CHILDREN (AGE RANGE: 1-7 years) who were scheduled to undergo inguinal herniorrhaphy were divided into 2 groups: the caudal block group and the splash block group with 15 children in each group. Tracheal intubation was performed. Fifteen children received caudal block with 1.0 ml/kg of 0.25% ropivacaine (Group 1). Caudal block was performed using the loss of resistance method via the sacral hiatus. Fifteen children in Group 2 received local instillation (splash block) in the surgical site with up to 0.4 ml/kg of 0.25% ropivacaine. The patients were observed for 90 minutes in the postanesthesia care unit and then they were transferred to the ward. The pain scores were taken 4 times. We assessed pain using the Faces pain scores. There were no significant differences between the groups regarding the pain scores at 10, 30 and 60 minutes upon entering the postanesthesia care unit. The pain scores of Group 1 were slightly lower at the last evaluation point when compared to that of Group 2. One patient in Group 1 required supplemental postoperative intravenous (IV) tramadol, while all the other patients in both groups did not require supplemental IV tramadol. The intraoperative requirement for sevoflurane was decreased in Group 1 as compared to that of Group 2. There were no major complications related to either type of block. We conclude that a splash block can have a similar analgesic effect as that of a caudal block for the postoperative herniorrhaphy pain of children.

The tramadol and paracetamol combination is used frequently for postoperative pain management. The literature on the use of this combination for vertebral surgery is limited. Our objective was to compare a combination of paracetamol 1 g and a lower dose of tramadol (1 mg/kg: group 1T) with a combination of paracetamol 1 g and a higher dose of tramadol (1.5 mg/kg: group 1.5T) for postoperative pain after microdisectomy surgery. Our main outcome measure was Visual Analogue Scale pain scores for 4 hours postoperatively. This prospective randomized triple-blind clinical trial was conducted at Aga Khan University Hospital, Karachi. Ninety-four patients aged between 18 and 50 years scheduled for elective single-level microdisectomy were allocated randomly into 1 of 2 groups. Twenty minutes before the end of the surgery, patients received the study drugs. There was no significant demographic difference between groups. None of the patients experienced severe pain (VAS>6). There was no significant difference in the mean pain score between groups. The mean score at 4 hours was 2.17 (1.38) in group 1.5T and 1.74 (1.37) in group 1T. The difference was not statistically significant (P=0.14). In group 1.5T, 13 patients reported having nausea and vomiting compared with 2 patients in group 1T. This was a statistically significant difference (P=0.004). The sedation score was similar between groups. The combination of low-dose tramadol (1 mg/kg) and paracetamol has comparable analgesia and a decreased incidence of nausea and vomiting compared with the higher dose of tramadol (1.5 mg/kg) and paracetamol combination.

Unrelieved post-operative pain continues to be a major clinical challenge, despite advances in management. Although nurses have embraced a crucial role in pain management, its extent is often limited in Iranian nursing practice. To determine Iranian nurses' perceptions of the barriers and facilitators influencing their management of post-operative pain. This study was qualitative with 26 participant nurses. Data were obtained through semi-structured serial interviews and analysed using the content analysis method. Several themes emerged to describe the factors that hindered or facilitated post-operative pain management. These were grouped into two main themes: (1) barriers to pain management after surgery with subgroups such as powerlessness, policies and rules of organization, physicians leading practice, time constraints, limited communication, interruption of activities relating to pain, and (2) factors that facilitated post-operative pain management that included the nurse-patient relationship, nurses' responsibility, the physician as a colleague, and nurses' knowledge and skills. Postoperative pain management in Iran is contextually complex, and may be controversial. Participants believed that in this context accurate pain management is difficult for nurses due to the barriers mentioned. Therefore, nurses make decisions and act as a patient comforter for pain after surgery because of the barriers to effective pain management.

Background AMPAkines augment the function of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in the brain to increase excitatory outputs. These drugs are known to relieve persistent pain. However, their role in acute pain is unknown. Furthermore, a specific molecular and anatomic target for these novel analgesics remains elusive. Methods We studied the analgesic role of an AMPAkine, CX546, in a rat paw incision (PI) model of acute postoperative pain. We measured the effect of AMPAkines on sensory as well as depressive symptoms of pain using mechanical hypersensitivity and forced swim tests. We asked whether AMPA receptors in the nucleus accumbens (NAc), a key node in the brain's reward and pain circuitry, can be a target for AMPAkine analgesia. Results Systemic administration of CX546 (n=13), compared with control (n=13), reduced mechanical hypersensitivity (50% withdrawal threshold of 6.05±1.30g (mean±SEM) vs. 0.62±0.13g), and it reduced depressive features of pain by decreasing immobility on the forced swim test in PI-treated rats (89.0±15.5s vs. 156.7±18.5s). Meanwhile, CX546 delivered locally into the NAc provided pain-relieving effects in both PI (50% withdrawal threshold of 6.81±1.91g vs. 0.50±0.03g; control n=6, CX546 n=8) and persistent postoperative pain (spared nerve injury – SNI) models (50% withdrawal threshold of 3.85±1.23g vs. 0.45±0.00g; control n=7, CX546 n=11). Blocking AMPA receptors in the NAc with 3-dihydroxy-6-nitro-7-sulfamoyl-benzo[f]quinoxaline-2, 3-dione (NBQX) inhibited these pain-relieving effects (50% withdrawal threshold of 7.18±1.52g vs. 1.59±0.66g; n=8 for PI groups; 10.70±3.45g vs. 1.39±0.88g; n=4 for SNI groups). Conclusions AMPAkines relieves postoperative pain by activating AMPA receptors in the NAc. PMID:27627816

Patellofemoral joint biomechanics contribute to anterior knee pain, instability, and dysfunction following total knee arthroplasty (TKA). Information about specific factors leading to anterior knee pain and dysfunction is currently limited. Changes in patellofemoral joint offset (PFO) refers to a mismatch between the preoperative and postoperative anteroposterior geometry of the patellofemoral joint. It remains unclear whether these changes lead to adverse outcomes in TKA. A retrospective radiographic review of 970 knees pre-TKA and post-TKA was completed to correlate the radiographic and clinical outcomes of changing the PFO using a posterior-stabilized single knee design with patellar resurfacing. A total of 970 patients were reviewed. Postoperatively, the anterior femoral offset, anteroposterior femoral size, and anterior patellar offset were changed in 40%, 60%, and 71% of knees, respectively, compared to preoperative values. The Western Ontario and McMasters Osteoarthritis Index total score as well as subscale scores for pain and function were not significantly affected by an increase or decrease in PFO. Similarly, Knee Society Scores and range of motion were not significantly affected. Increased anterior patellar offset was, however, associated with increased postoperative patellar tilt. Postoperative patellar tilt was not correlated with adverse patient satisfaction scores or loss of range of motion. Changes in PFO (decreased, maintained, or increased) are common post-TKA and are not associated with a difference in clinical outcomes. Increases in anterior patellar offset led to increased patellar tilt, which was not associated with adverse patient satisfaction scores. Copyright © 2016 Elsevier Inc. All rights reserved.

Cesarean delivery is a common surgery in the United States, with 1.3 million performed during 2009. 1 Obstetricians must balance the growing concern with opioid abuse, dependence, and side effects with optimal postoperative pain control. Intravenous acetaminophen may represent an additional method to decrease the reliance on opioid medications and improve postoperative pain following cesarean delivery. The objective of the study was to determine whether the administration of intravenous acetaminophen following routine scheduled cesarean delivery would decrease the need for narcotic medications to control postoperative pain. This was an institutional review board-approved, double-blind, placebo-controlled, randomized trial, registered on clinicaltrials.gov (number 02046382). Women scheduled to undergo cesarean delivery with regional anesthesia at term were recruited. All perioperative and postpartum care was standardized via study order sets. Study patients were given all medications in a standardized manner receiving either acetaminophen 1000 mg intravenously or 100 mL saline (placebo) every 8 hours for 48 hours for a total of 6 doses. The pharmacy prepared intravenous acetaminophen and saline in identical administration bags labeled study drug to ensure blinding. The initial dose of study drug was given within 60 minutes of skin incision. Quantity of breakthrough and scheduled analgesic medications and self-reported pain levels on the Faces Pain Scale (0-10) before and after study drug administration were collected. Patient demographics were extracted from the chart. Power calculation determined that 45 patients per arm were required to detect a 30% reduction in postcesarean narcotic requirement with 80% power and a significance level of P = .05. A total of 133 patients were consented for the study. Twenty-nine were excluded and 104 patients completed the study: 57 received intravenous acetaminophen and 47 received placebo. There were no differences in baseline demographic characteristics including patient age, body mass index, gravidity, parity, race, comorbidities, or number of prior cesarean deliveries. There were no differences between groups in estimated blood loss or length of stay. The total amount of oral narcotic medications consumed by patients receiving intravenous acetaminophen was significantly reduced when compared with the placebo group (47 mg vs 65 mg of oxycodone; P = .034). The total amount of ibuprofen used between groups was not different. There was no difference in pain scores between groups before and after study dose administration. There was no significant difference in narcotic side effects (nausea/emesis, respiratory depression, constipation) in either study arm. Intravenous acetaminophen in the postoperative period following cesarean delivery resulted in a significant decrease in oral narcotic consumption for pain control. Copyright © 2017 Elsevier Inc.

Hirst, Lawrence W

2013-06-01

To describe the result of using a polyethylene glycol hydrogel contact lens (ReSure; Ocular Therapeutix, Inc, Bedford, MA) as a protective bandage over denuded areas of Tenons after pterygium removal. Five sequential patients underwent pterygium removal with a conjunctival autograft and painting of bare Tenons in the area of the graft retrieval with a biodegradable polymer, and these patients were followed for 1 year for immediate postoperative pain, epithelial healing, and long-term conjunctival scarring. All patients showed prolonged persistence of the polymer for up to 8 to 10 weeks with resultant increased conjunctival inflammation and scarring with no evidence of decreased postoperative pain. This hydrogel polymer seems to cause prolonged inflammation and resultant scarring when used over extended areas of Tenons, and it has no role in reducing pain after pterygium surgery.

Splanchnicectomy has been evaluated for treatment of chronic pain in both pancreatic cancer and chronic pancreatitis patients, although its efficacy has not been compared in these 2 patient populations. This study aimed to compare bilateral thoracoscopic splanchnicectomy in treatment of abdominal pain secondary with pancreatic cancer and chronic pancreatitis. A University of Louisville database was evaluated from July 1998 to March 2016 for patients undergoing bilateral thoracoscopic splanchnicectomy for intractable pain secondary to pancreatic cancer (n = 48) or chronic pancreatitis (n = 75). Patients were evaluated pre- and postoperatively with regard to abdominal pain and related symptoms, narcotic analgesic requirements, and hospital admissions. Narcotic use was quantified using the Kentucky All Schedule Prescription Electronic Reporting system. After bilateral thoracoscopic splanchnicectomy, 28% of pancreatic cancer patients continued to experience abdominal pain compared with 57% of chronic pancreatitis patients. Daily narcotic dose decreased for 74% of pancreatic cancer compared with 32% of chronic pancreatitis patients (p < 0.001). Sixty-seven percent of pancreatic cancer patients discontinued pain medications completely compared with 14% of chronic pancreatitis patients (p < 0.001). Hospitalizations decreased significantly in both groups (p < 0.001; p = 0.001), although mean number of postoperative hospitalizations was lower for pancreatic cancer (0.5) compared with chronic pancreatitis patients (2.80) (p < 0.001). Mean follow-up was significantly shorter for pancreatic cancer patients than for chronic pancreatitis patients (8 months vs 32 months; p < 0.001). Bilateral thoracoscopic splanchnicectomy safely, effectively, and durably relieves abdominal pain in patients with both pancreatic cancer and chronic pancreatitis. However, it is more effective in providing pain relief and preventing pain-related hospitalizations in patients with pancreatic cancer compared with those with chronic pancreatitis. Copyright © 2017.

Transversus abdominis plane (TAP) block using a short-acting local anesthetic as part of multimodal analgesia is efficient in various abdominal surgeries, including laparoscopic surgery. However, information regarding its use in laparoscopic colorectal surgery is still limited and sometimes controversial. Therefore, we conducted a systematic review and meta-analysis to determine whether TAP block using a short-acting anesthetic has a positive postoperative analgesic outcome in patients who have undergone laparoscopic colorectal surgery. We searched for studies comparing the postoperative pain outcome after laparoscopic colorectal surgery between patients who received TAP block and a control group (placebo or no treatment). Outcome measures were early pain at rest (numeric rating scale [NRS] score at 0-2 h postoperatively), late pain at movement (NRS score at 24 h postoperatively), late pain at rest (NRS score at 24 h postoperatively), and postoperative opioid consumption (up to 24 h postoperatively). We used a random-effects model for the meta-analysis and Egger's regression test to detect publication bias. We included six studies involving 452 patients (224 in the TAP block group, 228 in the control group). Early and late pain scores at movement were significantly different between the TAP block and control groups (standardized mean difference: - 0.695, P < 0.0001 for early pain and - 0.242, P = 0.029 for late pain). There was no significant difference between the TAP block and control groups in early pain at rest (P = 0.475), late pain at rest (P = 0.826), and postoperative opioid consumption (P = 0.257). The TAP block using a short-acting anesthetic had a significant effect on the postoperative pain outcome in the early (0-2 h) and late (24 h) period at movement. However, it did not have a significant effect on the postoperative pain outcome in the early (0-2 h) and late (24 h) periods at rest after laparoscopic surgery.

Periarticular infiltration of local anesthetic, NSAIDs, and adrenaline have been reported to reduce postoperative pain, improve mobility, and reduce hospital stay for patients having THAs, but available studies have not determined whether local anesthetic infiltration alone achieves similar improvements. We therefore asked whether periarticular injection of a local anesthetic during THA reduced postoperative pain and opioid requirements and improved postoperative mobility. We randomized 96 patients to either treatment (n = 50) or control groups (n = 46). Before wound closure, the treatment group received local infiltration of 160 mL of levobupivacaine with adrenaline. The control group received no local infiltration. We assessed postoperative morphine consumption and pain during the 24 hours after surgery. Mobilization was assessed 24 hours postoperatively with supine-to-sit and sit-to-stand transfers, timed 10-m walk test, and timed stair ascent and descent. Patients and assessing physiotherapists were blind to study status. We observed no differences in postoperative morphine consumption, time to ascend and descend stairs, or ability to transfer between treatment and control groups. The treatment group reported more pain 7 to 12 hours postoperatively, but there were no differences in pain scores between groups at all other postoperative intervals. The treatment group showed increased postoperative walking speed greater than 6 m, but not greater than 10 m, compared with the control group. Periarticular infiltration of local anesthetic during THA did not reduce postoperative pain or length of hospital stay and did not improve early postoperative mobilization.

Anterior cruciate ligament (ACL) tears are highly incident injuries in young athletes within our work area. The use of the patellar graft, despite being the treatment of choice, presents post-operative problems such as anterior knee pain, which limits its use and leads to preference being taken for alternative grafts. Our aim was to evaluate if the application of PRGF reduces anterior knee pain in donor site in BTB-ACL reconstruction. 43 patients were included in the double-blinded and randomized clinical trial comparing two patient groups who underwent ACL reconstruction using patellar tendon graft, comparing anterior knee pain with and without the application of PRGF at the donor site after harvesting the graft. The PRGF group showed decreased donor site pain in comparison to the control group, with significant differences in the first two months of follow-up. The application of PRGF decreased donor site pain compared to the control group.

Interference of postoperative pain on women's daily life after early discharge from cardiac surgery.

Women report more postoperative pain and problems performing domestic activities than men in the first month of recovery after cardiac surgery. The purpose of this article is to describe how women rate and describe pain interference with daily life after early discharge from cardiac surgery. A qualitative study was conducted in 2004-2005 with ten women recruited from a large Norwegian university hospital before discharge from their first elective cardiac surgery. Various aspects of the women's postoperative experiences were collected with qualitative interviews in the women's homes 8-14 days after discharge: a self-developed pain diary measuring pain intensity, types and amount of pain medication taken every day after returning home from hospital; and the Brief Pain Inventory-Short Form immediately before the interview. Qualitative content analysis was used to identify recurring themes from the interviews. Data from the questionnaires provided more nuances to the experiences of pain, pain management, and interference of postoperative pain. Postoperative pain interfered most with sleep, general activity, and the ability to perform housework during the first 2 weeks after discharge. Despite being advised at the hospital to take pain medication regularly, few women consumed the maximum amount of analgesics. Early hospital discharge after open cardiac surgery implies increased patient participation in pain management. Women undergoing this surgery need more information in hospital on why postoperative pain management beyond simple pain relief is important. (c) 2010 American Society for Pain Management Nursing.

2018-01-01

ABSTRACT Many hip arthroscopy patients experience significant pain in the immediate postoperative period. Although peripheral nerve blocks have demonstrated efficacy in alleviating some of this pain, they come with significant costs. Local infiltration analgesia (LIA) may be a significantly cheaper and efficacious treatment modality. Although LIA has been well studied in hip and knee arthroplasty, its efficacy in hip arthroscopy is unclear. The purpose of this retrospective study is to determine the efficacy of a single extracapsular injection of bupivacaine–epinephrine during hip arthroscopy in reducing the rate of elective postoperative femoral nerve blocks. A retrospective review of 100 consecutive patients who underwent primary hip arthroscopy at a single medical center was performed. The control group consisted of 50 patients before the implementation of the current LIA protocol, whereas another 50 patients received a 20-ml extracapsular injection of 0.25% bupivacaine–epinephrine under direct arthroscopic visualization after capsular closure. In the post-anesthesia care unit (PACU), patients were offered a femoral nerve block for uncontrolled pain. The rate of femoral nerve block, and total opioid consumption, was compared between groups. The proportion of patients receiving elective femoral nerve blocks was significantly less in the LIA group (34%) as compared with the control group (56%; P = 0.027). There was no significant difference in total PACU opioid consumption between groups (P = 0.740). The decreased utilization of postoperative nerve blocks observed in the LIA group suggests that LIA may improve postoperative pain management and should be considered as a potentially cost-effective tool in pain management in hip arthroscopy patients.

Several techniques of anesthesia are used in foot surgery. Preemptive analgesia helps to prevent the development of hypersensitivity in the perioperative period. The aim of our study was to assess the role of preemptive local anesthetic infiltration and postoperative pain after hallux valgus surgery. We evaluated 118 patients who underwent modified chevron and mini-invasive Mitchell-Kramer bunionectomy of the first distal metatarsal. After spinal anesthesia each patient randomly received an infiltration of local anesthetic or the same amount of normal saline 10 minutes before the skin incision. We measured the intensity of pain 4, 8, 12, 16, 24, and 72 hours after the release of the tourniquet using a visual analogue scale (VAS). Rescue analgesia and all other side effects were noted. Preemptive analgesia resulted in less pain during the first 24 hours after surgery. The decrease of VAS score was significantly lower in the study group during all the short postoperative periods measured. The rescue analgesia was administered in 11.9% of patients in the injected group and 42.4% in the placebo group (P < .05). In the injected group we did not observe significant difference in VAS score between patients post-chevron and miniinvasive Mitchell-Kramer osteotomy of the first distal metatarsal. No systemic adverse effects were noted. One persistent injury of dorsomedial cutaneous nerve was observed. Preemptive local anesthetic infiltration was an efficient and safe method to reduce postoperative pain after hallux valgus surgery. The analgesic effect was satisfactory in both traditional and minimally invasive techniques. © The Author(s) 2014.

Objectives To assess the incidence of postoperative pain after single- and multi-visit endodontic treatment of teeth with vital and non-vital pulp. Methods In total, 306 patients with teeth requiring endodontic treatment were identified and were included in this study. Two experienced clinicians treated the patients, who were randomly assigned to two groups. While the teeth of patients in group 1 were obturated, group 2 were temporarily sealed and obturated after one week. Three days after the root canal instrumentation of each tooth, the patients were asked whether they experienced any postoperative pain and to rate the level of discomfort as no, mild, moderate, or severe pain. Data were analyzed statistically using the chi-square test. Results No significant difference in postoperative pain was found between vital and non-vital teeth (P>.01). Mild, moderate, and severe pain occurred in 31.4, 13.7, and 4.6% of vital teeth, respectively. Postoperative pain occurred in 107 (69.9%) and 106 (69.3%) teeth in the single- and multi-visit treatment groups, respectively. There was no significant difference in postoperative pain between the two groups (P>.01). Conclusions The prevalence of postoperative pain did not differ between vital and non-vital teeth. The majority of patients in either groups reported no or only mild pain. PMID:19826598

Retrospective cohort review. To assess whether immediate postoperative neck pain scores accurately predict 12-month visual analog scale-neck pain (VAS-NP) outcomes following Anterior Cervical Discectomy and Fusion surgery (ACDF). This was a retrospective study of 82 patients undergoing elective ACDF surgery at a major academic medical center. Patient reported outcomes measures VAS-NP scores were recorded on the first postoperative day, then at 6-weeks, 3, 6, and 12-months after surgery. Multivariate correlation and logistic regression methods were utilized to determine whether immediate postoperative VAS-NP score accurately predicted 1-year patient reported VAS-NP Scores. Overall, 46.3% male, 25.6% were smokers, and the mean age and body mass index (BMI) were 53.7 years and 28.28 kg/m 2 , respectively. There were significant correlations between immediate postoperative pain scores and neck pain scores at 6 weeks VAS-NP ( P = .0015), 6 months VAS-NP ( P = .0333), and 12 months VAS-NP ( P = .0247) after surgery. Furthermore, immediate postoperative pain score is an independent predictor of 6 weeks, 6 months, and 1 year VAS-NP scores. Our study suggests that immediate postoperative patient reported neck pain scores accurately predicts and correlates with 12-month VAS-NP scores after an ACDF procedure. Patients with high neck pain scores after surgery are more likely to report persistent neck pain 12 months after index surgery.

Liposomal bupivacaine (LB) is a long-acting local anesthetic reported to decrease postoperative pain in adults. The authors demonstrate the safe use of LB in pediatric patients with improved pain control following palatoplasty. Retrospective patient series of all single-surgeon palatoplasty patients treated at a tertiary craniofacial center from August 2014 to December 2015 were included. All patients received 1.3% LB intraoperatively as greater palatal nerve and surgical field blocks in 2-flap V-Y pushback palatoplasty. Postoperative oral intake, opioids administered, duration of hospitalization, and FLACC (face, legs, activity, cry, consolability) pain scores were measured. Twenty-seven patients (16 males and 11 females, average age of 10.8 months, weight 8.8 kg) received 2.9 ± 0.9 mL (2.6 ± 1.9 mg/kg) 1.3% LB. Average FLACC scores were 2.4 ± 2.2/10 in the postanesthesia care unit and 3.8 ± 1.8/10 while inpatients. Oral intake was first tolerated 10.3 ± 11.5 hours postoperatively and tolerated 496.4 ± 354.2 mL orally in the first 24 hours postoperatively. Patients received 8.5 ± 8.4 mg hydrocodone equivalents (0.46 ± 0.45 mg/kg per d hydrocodone equivalents) and were discharged 2.1 ± 1.3 days postoperatively. Opioid-related adverse events included emesis in 7.4% and pruritis in 3.7% of patients. The LB may be used safely in pediatric patients. Intraoperative injection of LB during palatoplasty can yield low postoperative opioid use and an early and adequate volume of oral intake over an average hospital stay. Further cost-efficacy studies of LB are needed to assess its value in pediatric plastic surgery.

The objective of this study was to determine the prevalence, severity, and duration of postoperative pain in children undergoing general anesthesia for dentistry. This prospective cross-sectional study included 33 American Society of Anesthesiology (ASA) Class I and II children 4–6 years old requiring multiple dental procedures, including at least 1 extraction, and/or pulpectomy, and/or pulpotomy of the primary dentition. Exclusion criteria were children who were developmentally delayed, cognitively impaired, born prematurely, taking psychotropic medications, or recorded baseline pain or analgesic use. The primary outcome of pain was measured by parents using the validated Faces Pain Scale-Revised (FPS-R) and Parents' Postoperative Pain Measure (PPPM) during the first 72 hours at home. The results showed that moderate-to-severe postoperative pain, defined as FPS-R ≥ 6, was reported in 48.5% of children. The prevalence of moderate-to-severe pain was 29.0% by FPS-R and 40.0% by PPPM at 2 hours after discharge. Pain subsided over 3 days. Postoperative pain scores increased significantly from baseline (P < .001, Wilcoxon matched pairs signed rank test). Moderately good correlation between the 2 pain measures existed 2 and 12 hours from discharge (Spearman rhos correlation coefficients of 0.604 and 0.603, P < .005). In conclusion, children do experience moderate-to-severe pain postoperatively. Although parents successfully used pain scales, they infrequently administered analgesics. PMID:26650492

The aim of this study was to evaluate the effects of perioperative psychological and music interventions in elderly patients undergoing elective surgery on anxiety, post-operative pain, and changes in heart rate variability (HRV) to ascertain if perioperative psychological and music interventions can affect overall anxiety levels. Fourty elderly patients undergoing elective surgery were randomized to two groups; one group received psychological and music intervention, and the other was the control. The intervention group underwent psychological intervention and listening to music for 30 min before surgery. The mean change in HRV as determined by low frequency (LF) power measurements. After the intervention, the ratio of mean LF to high frequency (HF) power decreased significantly in the intervention group compared to before the intervention (p<0.05). In the control group, mean LF measurements and the ratio of LF:HF did not change significantly. In the intervention group, mean HF power was significantly higher after the procedure than before (p<0.01). Moreover, the mean self-rating anxiety score of the intervention group decreased after the procedure compared to before (p<0.05). The mean visual analogue score of the intervention group 6 hours after surgery was significantly lower than that of the control group (p<0.01). Perioperative psychological and music interventions can reduce anxiety and postoperative pain in elderly patients.

Epidural technique for postoperative pain: gold standard no more?

PubMed

Rawal, Narinder

2012-01-01

Epidural analgesia is a well-established technique that has commonly been regarded as the gold standard in postoperative pain management. However, newer, evidence-based outcome data show that the benefits of epidural analgesia are not as significant as previously believed. There are some benefits in a decrease in the incidence of cardiovascular and pulmonary complications, but these benefits are probably limited to high-risk patients undergoing major abdominal or thoracic surgery who receive thoracic epidural analgesia with local anaesthetic drugs only. There is increasing evidence that less invasive regional analgesic techniques are as effective as epidural analgesia. These include paravertebral block for thoracotomy, femoral block for total hip and knee arthroplasty, wound catheter infusions for cesarean delivery, and local infiltration analgesia techniques for lower limb joint arthroplasty. Wound infiltration techniques and their modifications are simple and safe alternatives for a variety of other surgical procedures. Although pain relief associated with epidural analgesia can be outstanding, clinicians expect more from this invasive, high-cost, labour-intensive technique. The number of indications for the use of epidural analgesia seems to be decreasing for a variety of reasons. The decision about whether to continue using epidural techniques should be guided by regular institutional audits and careful risk-benefit assessment rather than by tradition. For routine postoperative analgesia, epidural analgesia may no longer be considered the gold standard.

Postoperative pain management techniques in hip and knee arthroplasty.

Adequate control of postoperative pain following hip and knee arthroplasty can be a challenging task fraught with potential complications. Postoperative pain is perceived by the patient via a complex network and a multitude of molecular messengers in both the peripheral and central nervous systems. This allows the physician to modulate pain via an array of medications that act on different sites within the body. Using both contemporary and traditional pain modulators, the delivery and timing of these medications can affect postoperative pain and, ultimately, rehabilitation of the arthroplasty patient. Current techniques for controlling pain use both multimodal and preemptive analgesia to improve the outcome of the surgery while minimizing the potential adverse effects of the medications given.

To compare the efficacy of a transdermal buprenorphine patch (5, 10, 15, and 20 μg/h) with that of oral tramadol (150, 200, 250, and 300 mg) for postoperative pain control after single level spinal fusion surgery. The present study (ClinicalTrials.gov, number NCT02416804) was a prospective, randomized controlled non-inferiority trial designed to determine the efficacy of buprenorphine TDS for alleviating postoperative pain following patient controlled analgesia (PCA) in persons underwent a single level posterior lumbar interbody fusion surgery through 1:1 allocation. The primary outcome was the Visual Analog Pain Scale (VAS) score for postoperative back pain at 7 days after surgery. The non-inferior margin of the VAS was set at δ = 1.5 points. The VAS score (primary outcome) for postoperative back pain at 7 days after surgery in the Buprenorphine group was not inferior compared to the Tramadol group. The overall changes in VAS scores for postoperative pain during follow-up assessments over a 2-week period did not differ between both groups. However, the VAS scores for postoperative pain significantly improved with time after surgery in both groups. The patterns of changes in the VAS scores for postoperative pain during the follow-up period were not significantly different between the both groups. The efficacy of buprenorphine TDS was not inferior to that of oral tramadol medication for alleviating postoperative pain in the subacute period from 72 h after surgery, following PCA administration. In addition, adverse events were similar between both groups.

Swedish health care is regulated to involve the patient in every intervention process. In the area of post-operative pain, it is therefore important to evaluate patient experience of the quality of pain management. Previous research has focused on mapping this area but not on comparing experiences between acutely and electively admitted patients. Hence, the aim of this study was to investigate the experiences of post-operative pain management quality among acutely and electively admitted patients at a Swedish surgical department performing soft-tissue surgery. A survey study design was used as a method based on a multidimensional instrument to assess post-operative pain management: Strategic and Clinical Quality Indicators in Postoperative Pain Management (SCQIPP). Consecutive patients at all wards of a university hospital's surgical department were included. Data collection was performed at hospital discharge. In total, 160 patients participated, of whom 40 patients were acutely admitted. A significant difference between acutely and electively admitted patients was observed in the SCQIPP area of environment, whereas acute patients rated the post-operative pain management quality lower compared with those who were electively admitted. There may be a need for improvement in the areas of post-operative pain management in Sweden, both specifically and generally. There may also be a difference in the experience of post-operative pain quality between acutely and electively admitted patients in this study, specifically in the area of environment. In addition, low levels of the perceived quality of post-operative pain management among the patients were consistent, but satisfaction with analgesic treatment was rated as good. © 2015 John Wiley & Sons, Ltd.

Post-operative pain relief in chronic pancreatitis (CP) is variable. Our objective was to determine clinical imaging or histopathologic predictor(s) of post-operative pain relief in CP patients undergoing the Whipple or Frey procedure. All patients who underwent a Whipple (n = 30) or Frey procedure (n = 30) for painful CP between January 2003 and September 2013 were evaluated. A toxic etiology was defined as a history of alcohol use and/or smoking. The pre-operative abdominal CT was evaluated for calcification(s) and main pancreatic duct (MPD) dilation (≥5 mm). The post-operative histopathology was evaluated for severe fibrosis. Clinical imaging and histopathologic features were evaluated as predictors of post-operative pain relief using univariable and multivariable regression analysis. A total of 60 patients (age 51.6 years, 53% males) were included in our study, of whom 42 (70%) reported post-operative pain relief over a mean follow-up of 1.1 years. There were 37 (62%) patients with toxic etiology, 36 (60%) each with calcification(s) and MPD dilation. A toxic etiology, calcifications, and severe fibrosis were associated with post-operative pain relief on univariable analysis (all p < 0.01). However, only a toxic etiology was an independent predictor of post-operative pain relief (OR 5.7, 95% CI 1.3, 24.5, p = 0.02). Only a toxic etiology, and not imaging or histopathologic findings, independently predicts post-operative pain relief in CP patients undergoing the Whipple or Frey procedure.

Perioperative handling of surgical patients with opioid dependency represents an important clinical problem. Animal studies suggest that ketamine attenuates central sensitization and hyperalgesia and thereby reduces postoperative opioid tolerance. We hypothesized that intraoperative ketamine would reduce immediate postoperative opioid consumption compared with placebo in chronic pain patients with opioid dependency undergoing lumbar spinal fusion surgery. Primary outcome was morphine consumption 0 to 24 hours postoperatively. Secondary outcomes were acute pain at rest and during mobilization 2 to 24 hours postoperatively (visual analogue scale), adverse events, and persistent pain 6 months postoperatively. One hundred fifty patients were randomly assigned to intraoperative S-ketamine bolus 0.5 mg/kg and infusion 0.25 mg·kg·h or placebo. Postoperatively, patients received their usual opioids, paracetamol and IV patient-controlled analgesia with morphine. In the final analyses, 147 patients were included. Patient-controlled analgesia IV morphine consumption 0 to 24 hours postoperatively was significantly reduced in the ketamine group compared with the placebo group: 79 (47) vs 121 (53) mg IV, mean difference 42 mg (95% confidence interval -59 to -25), P < 0.001. Sedation was significantly reduced in the ketamine group 6 and 24 hours postoperatively. There were no significant differences regarding acute pain, nausea, vomiting, hallucinations, or nightmares. Back pain at 6 months postoperatively compared with preoperative pain was significantly more improved in the ketamine group compared with the placebo group, P = 0.005. In conclusion, intraoperative ketamine significantly reduced morphine consumption 0 to 24 hours after lumbar fusion surgery in opioid-dependent patients. The trend regarding less persistent pain 6 months postoperatively needs further investigation.

Polio infection can often lead to orthopedic complications such as arthritis, osteoporosis, muscle weakness, skeletal deformation, and chronic instability of the joints. The purpose of this study was to assess the outcomes and associated complications of arthroplasty in shoulders with sequelae of poliomyelitis. Seven patients (average age, 70 years) were treated between 1976 and 2013 with shoulder arthroplasty for the sequelae of polio. One patient underwent reverse shoulder arthroplasty, 2 had a hemiarthroplasty, and 4 had total shoulder arthroplasty. Average follow-up was 87 months. Outcome measures included pain, range of motion, and postoperative modified Neer ratings. Overall pain scores improved from 5 to 1.6 points (on a 5-point scale) after shoulder arthroplasty. Six shoulders had no or mild pain at latest follow-up, and 6 shoulders rated the result as much better or better. Mean shoulder elevation improved from 72° to 129°, and external rotation improved from 11° to 56°. Average strength in elevation decreased from 3.9 to 3.4 postoperatively, and external rotation strength decreased from 3.9 to 3.3. This, however, did not reach significance. Evidence of muscle imbalance with radiographic instability was found in 4 shoulders that demonstrated superior subluxation, anterior subluxation, or both. This remained asymptomatic. No shoulder required revision or reoperation. Shoulder arthroplasty provides significant pain relief and improved motion in patients with sequelae of poliomyelitis. Muscle weakness may be responsible for postoperative instability, and careful selection of the patient with good upper extremity muscles must be made.

Postoperative management of pain after total joint arthroplasty remains a challenge despite advancements in analgesics. Evidence shows that complementary modalities with mind-body and tactile-based approaches are valid and effective adjuncts to reduce pain and anxiety postoperatively. To investigate the effectiveness of the "M" Technique (M), a registered method of structured touch using a set sequence and number of strokes, and a consistent level of pressure on hands and feet, compared with guided imagery and usual care, for the reduction of pain and anxiety in patients undergoing elective total knee or hip replacement surgery. Randomized controlled trial: M-TIJRP (MiTechnique and guided Imagery in Joint Replacement Patients [Mighty Junior P]). At a community hospital, 225 male and female patients, aged 38 to 90 years, undergoing elective total hip or knee replacement were randomly assigned to 1 of 3 groups (75 patients in each): M, guided imagery, or usual care. They were blinded to their assignment until the intervention. Reduction of pain and anxiety postoperatively. Secondary outcomes measured use of pain medication and patient satisfaction. This study yielded positive findings for the management of pain and anxiety in patients undergoing elective joint replacement using M and guided imagery for 18 to 20 minutes compared with usual care. M showed the largest predicted decreases in both pain and anxiety between groups. There was no significant difference in narcotic pain medication use between groups. Patient satisfaction survey ratings were highest for M, followed by guided imagery. The benefit of M may be because of the specifically structured sequence of touch by competent caring, trained providers.

To evaluate the effects of music listening on pain intensity and pain distress on the first and second postoperative days in abdominal surgery patients and the long-term effects of music on the third postoperative day. Music has been found to relieve pain intensity in surgery patients. There are only a few studies on music intervention in abdominal surgery. Music intervention studies assessing multidimensional pain such as pain intensity and pain distress are also scarce. Prospective clinical study with two parallel groups. Patients undergoing elective abdominal surgery (n = 168) were divided into either a music group (n = 83) or a control group (n = 85). Patients assessed pain intensity and pain distress in bed rest, during deep breathing and in shifting position once in the evening of the operation day and on the first and second postoperative days in the morning, at noon and in the evening. On the third postoperative day, the patients assessed their pain intensity and pain distress only once. In the music group, the patients' pain intensity and pain distress in bed rest, during deep breathing and in shifting position were significantly lower on the second postoperative day compared with control group of patients. On the third postoperative day, when long-term effects of music on pain intensity and pain distress were assessed, there were no significant differences between music and control groups. This study demonstrates that the use of music alleviates pain intensity and pain distress in bed rest, during deep breathing and in shifting position after abdominal surgery on the second postoperative day. Music intervention is safe, inexpensive and easily used to improve the healing environment for abdominal surgery patients. Music intervention should be offered as an adjunct alternative to pharmacological pain relief after abdominal surgery in nursing practice. © 2011 Blackwell Publishing Ltd.

Postoperative pain management in animals is complicated greatly by the inability to recognize pain. As a result, the choice of analgesics and their doses has been based on extrapolation from greatly differing pain models or the use of measures with unclear relevance to pain. We recently developed the Mouse Grimace Scale (MGS), a facial-expression–based pain coding system adapted directly from scales used in nonverbal human populations. The MGS has shown to be a reliable, highly accurate measure of spontaneous pain of moderate duration, and therefore is particularly useful in the quantification of postoperative pain. In the present study, we quantified the relative intensity and duration of postoperative pain after a sham ventral ovariectomy (laparotomy) in outbred mice. In addition, we compiled dose–response data for 4 commonly used analgesics: buprenorphine, carprofen, ketoprofen, and acetaminophen. We found that postoperative pain in mice, as defined by facial grimacing, lasts for 36 to 48 h, and appears to show relative exacerbation during the early dark (active) photophase. We find that buprenorphine was highly effective in inhibiting postoperative pain-induced facial grimacing in mice at doses equal to or lower than current recommendations, that carprofen and ketoprofen are effective only at doses markedly higher than those currently recommended, and that acetaminophen was ineffective at any dose used. We suggest the revision of practices for postoperative pain management in mice in light of these findings. PMID:22330867

Intrathecal patient-controlled analgesia (IT-PCA) through implanted intrathecal infusion pumps has been increasingly utilized for severe cancer and chronic noncancer pain management. However, its application for acute postoperative pain management has not been reported to date. We present a case of a patient with an implanted intrathecal pump for chronic nonmalignant back pain who underwent an extensive spinal fusion surgery. The IT-PCA functionality of her intrathecal pump was successfully integrated into her postoperative multimodal pain regimen. Hence, IT-PCA can be safely incorporated into acute postoperative pain management with vigilant monitoring and close multidisciplinary collaboration.

Background Given their ability to process highly dimensional datasets with hundreds of variables, machine learning algorithms may offer one solution to the vexing challenge of predicting postoperative pain. Methods Here, we report on the application of machine learning algorithms to predict postoperative pain outcomes in a retrospective cohort of 8071 surgical patients using 796 clinical variables. Five algorithms were compared in terms of their ability to forecast moderate to severe postoperative pain: Least Absolute Shrinkage and Selection Operator (LASSO), gradient-boosted decision tree, support vector machine, neural network, and k-nearest neighbor, with logistic regression included for baseline comparison. Results In forecasting moderate to severe postoperative pain for postoperative day (POD) 1, the LASSO algorithm, using all 796 variables, had the highest accuracy with an area under the receiver-operating curve (ROC) of 0.704. Next, the gradient-boosted decision tree had an ROC of 0.665 and the k-nearest neighbor algorithm had an ROC of 0.643. For POD 3, the LASSO algorithm, using all variables, again had the highest accuracy, with an ROC of 0.727. Logistic regression had a lower ROC of 0.5 for predicting pain outcomes on POD 1 and 3. Conclusions Machine learning algorithms, when combined with complex and heterogeneous data from electronic medical record systems, can forecast acute postoperative pain outcomes with accuracies similar to methods that rely only on variables specifically collected for pain outcome prediction.

This study examined the hypothesis that ipsilateral upper extremity elevation for muscle-sparing thoracotomy procedures contributes to the postoperative shoulder pain. Prospective observational study. Medical center. ASA physical status 1-2 patients undergoing elective lung surgeries including pneumonectomy, lobectomy, and segmentectomy performed through either the anterolateral approach or video-assisted thoracotomy surgery. Postoperative observation of ipsilateral shoulder pain. Postoperative examinations of sites of shoulder pain (clavicle, anterior, lateral,or posterior aspect of acromion, posterior neck, supraspinatus, infraspinatus, and these entire areas) with or without trigger points, visual analog scale score of wound pain, and requested counts of analgesics. The number of patients who suffered from postoperative shoulder pain was 37 of 70 (52.9%). Demographic data, anterolateral/VATS ratio, VAS scores, and requested counts of rescue analgesics requirement were similar in the groups of patients with and without postoperative shoulder pain. The segmentectomy caused a significantly higher incidence of postoperative shoulder pain compared with other procedures (p < 0.05). The supra- and infraspinatus were significantly higher areas of painful regions compared to the other sites. The 16 of 37 patients (43.2%) with shoulder pain showed defined trigger points in their painful areas. These results supported the hypothesis that myofascial involvement contributed, to some extent, to shoulder pain after muscle-sparing thoracotomy with ipsilateral upper extremity elevation.

The aim of this study was to evaluate postoperative pain in patients who had a single tooth or multiple erupted teeth extracted. This research evaluated 520 consecutive dental extraction surgeries in which 680 teeth were removed. Data collection was obtained through a questionnaire of patients and of the undergraduate students who performed all procedures. Pain was evaluated through qualitative self-reported scores at seven days postsurgery. An increased pain level was statistically associated with ostectomy, postoperative complications, and tobacco consumption. Pain that persisted for more than two days was statistically associated with the amount of anesthetic solution used, with a notable increase in surgical time and development of postoperative complications. Periods of pain lasting more than two days could be expected for traumatic surgeries lasting more than 30 minutes. Both severe and prolonged pain were signs of development of postoperative complications, such as alveolar osteitis and alveolar infection.

To evaluate the effectiveness of hand massage on the pain and anxiety of the cardiac surgery critically ill. A three-arm randomized controlled trial. This study was conducted in a medical-surgical intensive care unit in Canada. Adult patients who underwent elective cardiac surgery, who were able to speak French/English and to self-report symptoms, without a high risk of postoperative complications were eligible. Patients were randomly allocated to standard care plus either two 20-minute hand massages (experimental), two 20-minute hand holdings (active control), or two 20-minute rest periods (passive control/standard care). Pain intensity, pain unpleasantness, anxiety, muscle tension, and vital signs were evaluated before, after, and 30 minutes later for each intervention. From the 83 patients recruited, 60 were randomized (20 massage, 19 hand holding, 21 standard care). After controlling for baseline scores, the massage group reported significantly lower pain intensity, pain unpleasantness, and anxiety for the first data collection set compared with both hand holding and standard care (analysis of covariance, P < 0.02), with an average decrease of two points on a 0-10 scale. No statistically significant differences were noted between hand holding and standard care for any of the symptoms. Similar results were observed for the second data collection set (N = 43). Patients had decreased muscle tension post massage. Vital signs did not differ significantly between groups. Findings suggest that a 20-minute hand massage in addition to routine postoperative pain management can concomitantly reduce pain intensity, pain unpleasantness, and anxiety by two points on average on a 0-10 scale.

Pain is one of the factors that decrease quality of life. Undergoing surgery is inevitably associated with the sensation of pain, which can affect a patient's level of acceptance of an illness. The aim of the study was to evaluate the level of acceptance of illness in patients undergoing surgical treatment with relation to the pain perceived by them during surgical treatment and to determine other factors that affect adaptation to illness among patients subjected to invasive treatment. The study was conducted on a group of 100 patients with mean age of 51.27 (SD=18.98) hospitalized in surgery departments in the Provincial Specialist Hospital in Wrocław, Poland, in April 2016. The Acceptance of Illness Scale (AIS) and the Visual Analog Scale (VAS) for pain were used. The mean score of VAS was 3.86 (SD =2.02). The mean score of AIS was 24.42 (SD =7.35). The level of acceptance of illness was significantly negatively correlated with the intensity of pain ( p <0.001; r =-0.498), the number of coexisting diseases ( p =0.002; r =-0.31), age ( p <0.001; r =-0.391), and the period of time since the operation ( p =0.007; r =-0.266). Patients taking analgesics showed a significantly lower acceptance of illness than those who did not ( p =0.009). A patient's place of living, education, and sex had no significant impact on their acceptance of illness. A higher level of pain translates into a lower adaptation to illness despite the use of analgesics, which may indicate that inadequate pain control leads to a decrease in the acceptance of illness. Further research on monitoring postoperative pain, as well as the development of postoperative prevention programs, is required.

Intravenous non-opioid analgesia for peri- and postoperative pain management: a scientific review of intravenous acetaminophen and ibuprofen

Pain is a predictable consequence following operations, but the management of postoperative pain is another challenge for anesthesiologists and inappropriately controlled pain may lead to unwanted outcomes in the postoperative period. Opioids are indeed still at the mainstream of postoperative pain control, but solely using only opioids for postoperative pain management may be connected with risks of complications and adverse effects. As a consequence, the concept of multimodal analgesia has been proposed and is recommended whenever possible. Acetaminophen is one of the most commonly used analgesic and antipyretic drug for its good tolerance and high safety profiles. The introduction of intravenous form of acetaminophen has led to a wider flexibility of its use during peri- and postoperative periods, allowing the early initiation of multimodal analgesia. Many studies have revealed the efficacy, safety and opioid sparing effects of intravenous acetaminophen. Intravenous ibuprofen has also shown to be well tolerated and demonstrated to have significant opioid sparing effects during the postoperative period. However, the number of randomized controlled trials confirming the efficacy and safety is small and should be used in caution in certain group of patients. Intravenous acetaminophen and ibuprofen are important options for multimodal postoperative analgesia, improving pain and patient satisfaction. PMID:25664148

Best multimodal analgesic protocol for total knee arthroplasty.

PubMed

Webb, Christopher A J; Mariano, Edward R

2015-01-01

Total knee arthroplasty is one of the most commonly performed operations in the USA. As with any elective joint surgery, the primary goal includes functional restoration that is not limited by pain. The use of peripheral nerve blocks for patients undergoing knee arthroplasty has resulted in decreased pain scores, improved early ambulation and decreased time to achieve hospital discharge criteria. Concern has been raised over the potential risks of femoral nerve block, and there has been growing support for the adductor canal block. It is the author's opinion that when not contraindicated, intraoperative neuraxial anesthesia combined with a continuous adductor canal block and a multimodal medication regimen for postoperative pain control is the best analgesic protocol for knee arthroplasty.

To compare postoperative pain, duration of surgery, and duration of anesthesia for 3 methods of ovariectomy in cats: (1) conventional ventral median open approach (Midline), (2) right flank approach (Flank), and (3) median 2-portal laparoscopic procedure (Lap). Randomized, prospective clinical trial. Healthy, sexually intact female cats (n = 60). Cats were randomly assigned to 1 of 3 groups: Midline (n = 20), Flank (20), and Lap (20) were evaluated 1, 2, 4, 6, and 12 hours after endotracheal extubation. Postoperative pain was scored using the 4A-vet pain scale that combines a subjective numerical pain rating and objective scoring of physiologic and behavioral variables including the response to stimulation of the surgical site. Pain scores (PS) were compared between groups. There was a significant difference in the PS between groups. PS for Midline and Flank were not significantly different but were both significantly higher compared with Lap. Depending on time, 5-20% of the cats had intense postoperative pain in both Midline and Flank groups. None of the Lap cats had intense postoperative pain. Laparoscopic ovariectomy, although slower, appeared less painful compared with conventional ventral midline and flank ovariectomy. Postoperative pain did not differ significantly between midline and flank groups. © Copyright 2014 by The American College of Veterinary Surgeons.

Tramadol was found to be more effective than dexamethasone in post-operative pain control, with long-lasting relief of pain. This study aimed to compare the effects of pre-operative local injections of tramadol and dexamethasone on post-operative pain, nausea and vomiting in patients who underwent tonsillectomy. Sixty patients between 3-13 years of age who were planned for tonsillectomy were included in the study. Patients were divided into three groups. Group 1 was the control group. Patients in Group 2 received 0.3 mg/kg Dexamethasone and Group 3 received 0.1 mg/kg Tramadol injection to the peritonsillary space just before the operation. Patients were evaluated for nausea, vomiting, and pain. When the control and the dexamethasone groups were compared; there were statistically significant differences in pain scores at post-operative 15 and 30 min, whereas there was no statistically significant difference in pain scores at other hours. When the control and tramadol groups were compared, there was a statistically significant difference in pain scores at all intervals. When tramadol and dexamethasone groups were compared, there was no statistically significant difference in pain scores at post-operative 15 and 30 min, 1 and 2 h, whereas there was a statistically significant difference in pain scores at post-operative 6 and 24 h.

2010-01-01

Electro-acupuncture (EA) can be effective in some pain conditions, but still there have been no randomized controlled studies of EA for treatment of acute postoperative pain in nasal septoplasty. Therefore, we did a study to test whether EA of specific points is superior to sham acupuncture for complementary analgesia after nasal septoplasty. Ninety (90) patients with an American Society of Anesthesiology (ASA) physical status of I-II scheduled for elective septoplasty were randomly allocated to acupuncture group or control group. Postoperative pain was treated with intravenous meperidine. The time to the first analgesic request, and pain intensity on a 100-mm visual analogue scale (VAS-100) were used to evaluate postoperative pain, and the amount of postoperative meperidine and incidence of analgesia related to side-effects were recorded. Postoperative pain intensity on VAS-100 and respiratory depression were similar in both groups (p > 0.05), but nausea and vomiting were less in the acupuncture group than in the control group (p < 0.05). Findings from our study demonstrate that both uses of EA and 0.1 mg/kg IV morphine given intraoperatively resulted in a similar postoperative pain score, and meperidine was not given in any patient in the two groups during postoperative period because the VAS scores of all patients were less than 40 mm.

Low degree of satisfactory individual pain relief in post-operative pain trials.

2017-01-01

The majority of clinical trials regarding post-operative pain treatment focuses on the average analgesic efficacy, rather than on efficacy in individual patients. It has been argued, that in acute pain trials, the underlying distributions are often skewed, which makes the average unfit as the only way to measure efficacy. Consequently, dichotomised, individual responder analyses using a predefined 'favourable' response, e.g. Visual Analogue Scale (VAS) pain scores ≤ 30, have recently been suggested as a more clinical relevant outcome. We re-analysed data from 16 randomised controlled trials of post-operative pain treatment and from meta-analyses of a systematic review regarding hip arthroplasty. The predefined success criterion was that at least 80% of patients in active treatment groups should obtain VAS < 30 at 6 and 24 h post-operatively. In the analysis of data from the randomised controlled trials, we found that at 6 h post-operatively, 50% (95% CI: 31-69) of patients allocated to active treatment reached the success criterion for pain at rest and 14% (95% CI: 5-34) for pain during mobilisation. At 24 h post-operatively, 60% (95% CI: 38-78) of patients allocated to active treatment reached the success criterion for pain at rest, and 15% (95% CI: 5-36) for pain during mobilisation. Similar results were found for trials from the meta-analyses. Our results indicate that for conventional, explanatory trials of post-operative pain, individual patient's achievement of a favourable response to analgesic treatment is rather low. Future pragmatic clinical trials should focus on both average pain levels and individual responder analyses in order to promote effective pain treatment at the individually patient level. © 2016 The Acta Anaesthesiologica Scandinavica Foundation.

The purpose of this study was to provide comprehensive long-term data about sports activity levels in patients following total knee arthroplasty (TKA) and to determine the impact of pre-operative function, pain and specific performed sports on the results. 236 patients who have undergone TKA for severe osteoarthritis of the knee were asked to provide specific information regarding exercised types of sports before surgery and after at least 10 years following TKA. Pre- and postoperative function and pain were evaluated by the use of Tegner-, WOMAC- and VAS Score. After a mean of 14.9 years, a significant improvement regarding pain and function was observed. Pre-operative Tegner- and WOMAC scores revealed significant positive correlations with the post-operative Tegner-Score. Accordingly, a high percentage of patients (70.9%) stayed actively involved in sports. Nevertheless, the number of performing patients has decreased according to the sports impact. 71.3% continued practising low-impact-, 43.7% intermediate-impact sports whereas only 16.4% kept performing high impact sports. We conclude that TKA is highly effective in long-time pain reduction as well as improvement of function. Additionally, we found considerable sports activities preserved in the investigated series. However, sports activities in particular, seem to decrease according to the impact of sports. PMID:27090945

The aim of this study was to assess postoperative pain in a prospective randomized clinical trial comparing two groups, using the Reciproc® system in one group and the ProTaper® rotary system in the other. The study included 78 male patients, aged 18-64 years (mean age of 26 years), with asymptomatic pulp necrosis in mandibular molar teeth (n = 78). The single-session endodontic treatment was performed by a single operator specialized in Endodontics. Mechanical preparation of the root canals was performed using the ProTaper® and Reciproc® instrumentation techniques. Postoperative pain was recorded using a verbal rating scale (VRS) and verbal description with well-defined categories at the three following time intervals: 24 h, 72 h, and 7 days after the endodontic procedure. The assessment of postoperative pain was recorded as no pain, mild pain, moderate pain, and severe pain or flare-up. Data were analyzed using the nonparametric Mann-Whitney test with the aid of the STATA® software. The incidence of postoperative pain in the ProTaper group (PT) 24 h after the endodontic procedure was 17.9 and 5.1 % after 72 h. In the Reciproc group (RP), the incidence after 24 h was 15.3 and 2.5 % after 72 h. No patients presented severe pain at the time intervals assessed. No significant difference (p > 0.05) in postoperative pain was found between the ProTaper® and Reciproc® instrumentation technique during endodontic treatment in this study. According to our findings and the results of the clinical trial, the occurrence of postoperative pain was low and similar between the reciprocating and rotary techniques during the time intervals assessed. These results are different from basic laboratory studies that affirm that the reciprocating techniques tend to promote more postoperative pain since extrusion of debris is greater.

To investigate the efficacy of postoperative scheduled intravenous acetaminophen to reduce the opioid use and enhance the recovery after esophagectomy. A propensity score-matched population was created using the 93 and 69 consecutive patients who underwent esophagectomy for esophageal cancer before and after the introduction of postoperative scheduled intravenous acetaminophen, and the short-term clinical outcomes were compared. Significant defervescence was demonstrated in the Acetaminophen group (A-group) compared with control group (C-group) during the perioperative period (p < 0.05), whereas no significant differences were observed in the postoperative inflammatory parameters. The incidence of postoperative complications was similar between the groups. The number of PCA pushes and the frequency of using other non-opioid analgesics were significantly smaller in the A-group than in the C-group (p < 0.05). Both daily and cumulative opioid uses were significantly smaller in the A-group than in the C-group (p < 0.05). The time to first flatus was significantly shorter in the A-group than in the C-group (p < 0.001). The day of first walking after surgery was significantly earlier in the A-group than in the C-group (1.0 versus 2.0 days, p = 0.003). The ICU stay (2.86 versus 3.61 days, p < 0.001) and the hospital stay (21.5 versus 26.0 days, p = 0.061) tended to be shorter in the A-group than in the C-group. Postoperative scheduled intravenous acetaminophen decreased the rate of opioid use without increasing the intensity of postoperative pain and may be a feasible new pain management option in the enhanced recovery after surgery protocol following esophagectomy.

It is well known that improving postoperative pain control in plastic surgery procedures leads to earlier mobilization, shortened hospital stay, reduced hospital costs, and increased patient satisfaction. The authors evaluate the use of abdominal field block injections with liposomal bupivicaine (Exparel; Pacira Pharmaceuticals, Inc, San Diego, California) in postoperative pain management in patients undergoing abdominoplasty with rectus plication. Case records from 64 female patients who underwent abdominoplasty with rectus plication were reviewed. We performed a total of 118 abdominoplasties with rectus plication, alone or in combination with other surgical procedures, from August 2012 to December 2012, but 54 patients were excluded from the series due to inadequate follow-up. Patients received liposomal bupivicaine injections in an abdominal field block fashion. Patient age, height, weight, and smoking status were recorded. Delivery of standardized postoperative intramuscular or intravenous injections and oral pain pills was recorded. Postoperative data and questionnaires were used to evaluate clinical efficacy. The average number of procedures (including abdominoplasty with rectus plication) per patient was 7. Average patient body mass index was 27 kg/m(2). Average pain scores were 3.5 (postoperative visit 1) and 2.8 (visit 2). The average number of oral pain pills required was 14 at the first postoperative visit and 11.5 at the second postoperative visit. Patients were able to resume normal activity at an average of 6.4 days. Our experience with liposomal bupivicaine injections for regional blocks in abdominoplasty with rectus plication indicates that patients experienced reduced postoperative pain, required less postoperative narcotic medication, and resumed both earlier ambulation and normal activity. Further investigation is warranted with more clinical cases to recommend the use of this medication for routine pain management after an abdominoplasty.

Little evidence is available on complementary therapies for anxiety and pain relief after caesarean delivery. The purpose of this study was to evaluate the effects of foot massage post-operatively in patients after caesarean delivery. 70 patients were divided to the study or control group after cesarean delivery. Patients in the study group had foot massages for 20 min after surgery. All patients underwent heart rate variability analysis (HRV) and scored their anxiety; pain intensity was evaluated using an 11-point numerical rating scale (NRS). In the study group the HRV, as measured by the low frequency power (LF) value and the LF-to-high frequency power (LF/HF) ratio during Holter assessment, was significantly less after foot massage intervention, but was not changed in the control group. Moreover, the HF value significantly increased and the anxiety score significantly decreased after foot massage intervention, but not in the control group. The pain intensity score obtained 60 min after the massage was significantly lower in the study group than the control group, as were the vital signs (respiratory rate, and systolic and diastolic blood pressure). Post-operative massage intervention can reduce anxiety and pain in patients after caesarean delivery. © Georg Thieme Verlag KG Stuttgart · New York.

Ambulatory surgical facility. Eighty otherwise healthy paediatric patients undergoing coblation or electrocautery tonsillectomy by a fellowship-trained paediatric otolaryngologist. (i) The number of post-operative days with severe pain based on subjective qualification by the caretaker, (ii) post-operative days with pain rated ≥ 5 on a scale of 1-10, (iii) post-operative days requiring oral paracetamol/acetaminophen with codeine solution and (iv) post-operative days until resumption of a regular diet were assessed and recorded daily using a post-operative pain survey as a form of daily diary that was returned at the 2-week follow-up visit. Patients were consecutively enrolled into two groups of 40 patients. Average ages were 5.2 years for coblation tonsillectomy and 6.0 years for electrocautery tonsillectomy. The average number of post-operative days with severe pain was 4.2 for coblation and 5.9 for electrocautery (P = 0.006), days rating pain ≥ 5 were 3.6 for coblation and 4.8 for electrocautery (P = 0.037), days of codeine use were 2.5 for coblation and 2.9 for electrocautery (P = 0.324), and days until resumption of a regular diet were 5.2 for coblation and 6.2 for electrocautery (0.329). Coblation tonsillectomy may reduce post-operative pain and the time until resumption of a regular diet compared to electrocautery tonsillectomy. © 2011 Blackwell Publishing Ltd.

Objective To determine whether pre- and post-operative administration of intravenous ibuprofen (IV-ibuprofen) can significantly decrease pain and morphine use when compared with placebo in adult orthopedic surgical patients. Design This was a multi-center, randomized, double-blind placebo-controlled trial. Setting This study was completed at eight hospitals; six in the United States and two in South Africa. Patients A total of 185 adult patients undergoing elective orthopedic surgery. Interventions Patients were randomized to receive either 800 mg IV-ibuprofen or placebo every 6 hours, with the first dose administered pre-operatively. Additionally, all patients had access to intravenous morphine for rescue. Outcome Measures Efficacy of IV-ibuprofen was demonstrated by measuring the patient's self assessment of pain using a visual analog scale (VAS; assessed with movement and at rest) and a verbal response scale (VRS). Morphine consumption during the post-operative period was also assessed. Results In the immediate post-operative period, there was a 25.8% reduction in mean area under the curve-VAS assessed with movement (AUC-VASM) in patients receiving IV-ibuprofen (P < 0.001); a 31.8% reduction in mean AUC-VAS assessed at rest (AUC-VASR; P < 0.001) and a 20.2% reduction in mean VRS (P < 0.001) compared to those receiving placebo. Patients receiving IV-ibuprofen used 30.9% less morphine (P < 0.001) compared to those receiving placebo. Similar treatment emergent adverse events occurred in both study groups and there were no significant differences in the incidence of serious adverse events. Conclusion Pre- and post-operative administration of IV-ibuprofen significantly reduced both pain and morphine use in orthopedic surgery patients in this prospective randomized placebo-controlled trial.

The purpose of this prospective, randomized, double-blind study was to determine ibuprofen versus ibuprofen/acetaminophen use for postoperative endodontic pain in symptomatic patients with a pulpal diagnosis of necrosis and an associated periapical radiolucency who were experiencing moderate to severe preoperative pain. We also recorded escape medication use. Seventy-one adult patients presenting for emergency endodontic treatment with a symptomatic maxillary or mandibular tooth with a pulpal diagnosis of necrosis, periapical radiolucent area, and moderate to severe pain participated in this study. The patients were randomly divided into 2 groups by random assignment and numeric coding. An emergency debridement of the tooth was completed with hand and rotary instrumentation. At the end of the appointment, the patients randomly received capsules of either 600 mg ibuprofen or 600 mg ibuprofen combined with 1000 mg acetaminophen (blinded to both operator and patient). Patients also received a 6-day diary to be completed after anesthesia wore off and every morning for 5 days. Patients were asked to record pain, symptoms, and the number of capsules taken. Patients received escape medication (Vicodin) if the study medication did not control their pain. Postoperative data were analyzed by randomization test and step-down Bonferroni method of Holm. There were decreases in pain levels and analgesic use over time for the ibuprofen and ibuprofen/acetaminophen groups. There was no statistically significant difference between the 2 groups for analgesic use or escape medication use. Approximately 20% of patients in both groups required escape medication to control pain. Copyright © 2011 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

Anterior and Posterior Interosseous Neurectomy for the Treatment of Chronic Dynamic Instability of the Wrist

The purpose of this study was to determine the results of combined anterior and posterior interosseous neurectomy (AIN/PIN) in patients with chronic wrist pain secondary to dynamic instability, and to determine the predictability of selective AIN/PIN blocks with respect to pain relief, grip strength, and outcome of the neurectomy. A prospectively accrued chronic wrist pain registry was undertaken. Inclusion criteria were patients with arthroscopically confirmed dynamic wrist instability who had undergone a diagnostic AIN/PIN injection, followed by a single dorsal incision neurectomy. All patients completed Disabilities of the Arm, Shoulder and Hand outcome questionnaires preoperatively and at intervals postoperatively. Pre- and postoperative range of motion, grip strength, and percentage pain relief were recorded. Over a 3-year period, 50 wrists (48 patients) were enrolled: average follow-up was 28 months (range: 24–42 months). The average improvement in grip strength after denervation was 16% (p = 0.076), the average improvement in subjective pain rating was 51% (p < 0.0001), and the average improvement in Disabilities of the Arm, Shoulder, and Hand scores was 15 points (p = 0.0039). Improvement of pain from diagnostic injections was not predictive of final improvement of pain; however, improvement in grip strength after diagnostic injections did correlate with improved grip strength after surgery. Lack of improvement in subjective pain rating or grip strength after diagnostic injection approached statistical significance. There was no decrease in range of motion postoperatively. Fourteen patients (16 wrists) failed as defined by need for subsequent surgery. The results of AIN/PIN neurectomy demonstrate that it may be an effective alternative to wrist salvage or reconstructive procedures within the first few years of follow-up. PMID:18780027

The recognition and measurement of pain in cattle are important in determining the necessity for and efficacy of analgesic intervention. The aim of this study was to record behaviour and determine the validity and reliability of an instrument to assess acute pain in 40 cattle subjected to orchiectomy after sedation with xylazine and local anaesthesia. The animals were filmed before and after orchiectomy to record behaviour. The pain scale was based on previous studies, on a pilot study and on analysis of the camera footage. Three blinded observers and a local observer assessed the edited films obtained during the preoperative and postoperative periods, before and after rescue analgesia and 24 hours after surgery. Re-evaluation was performed one month after the first analysis. Criterion validity (agreement) and item-total correlation using Spearman's coefficient were employed to refine the scale. Based on factor analysis, a unidimensional scale was adopted. The internal consistency of the data was excellent after refinement (Cronbach's α coefficient = 0.866). There was a high correlation (p < 0.001) between the proposed scale and the visual analogue, simple descriptive and numerical rating scales. The construct validity and responsiveness were confirmed by the increase and decrease in pain scores after surgery and rescue analgesia, respectively (p < 0.001). Inter- and intra-observer reliability ranged from moderate to very good. The optimal cut-off point for rescue analgesia was > 4, and analysis of the area under the curve (AUC = 0.963) showed excellent discriminatory ability. The UNESP-Botucatu unidimensional pain scale for assessing acute postoperative pain in cattle is a valid, reliable and responsive instrument with excellent internal consistency and discriminatory ability. The cut-off point for rescue analgesia provides an additional tool for guiding analgesic therapy.

To evaluate the effect of aromatherapy with Lavandula angustifolia essential oil on post-tonsillectomy pain in pediatric patients. This was a randomized controlled prospective clinical trial. In this study, 48 post-tonsillectomy patients aged 6-12 years were randomly assigned to two groups (24 patients in each group). After tonsillectomy surgery, all patients received acetaminophen (10-15 mg/kg/dose, PO) every 6h as necessary to relieve pain. The patients of the case group also inhaled lavender essential oil. The frequencies of daily use of acetaminophen and nocturnal awakening due to pain, and pain intensity (evaluated using visual analog scale [VAS]) were recorded for each patient for 3 days after surgery. Finally, the mean values of variables were compared between two groups separately for each post-operative day. The use of lavender essential oil caused statistically significant reduction in daily use of acetaminophen in all three post-operative days but had not significant effects on pain intensity and frequency of nocturnal awakening. Aromatherapy with lavender essential oil decreases the number of required analgesics following tonsillectomy in pediatric patients. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

There are no comparative randomised controlled trials of physiotherapy modalities for chronic low back and radicular pain associated with multilevel fusion. Physiotherapy-based rehabilitation to control pain and improve activation levels for persistent pain following multilevel fusion can be challenging. This is a case report of a 68-year-old man who was referred for physiotherapy intervention 10 months after a multilevel spinal fusion for spinal stenosis. He reported high levels of persistent postoperative pain with minimal activity as a consequence of his pain following the surgery. The physiotherapy interventions consisted of three phases of rehabilitation starting with pool exercise that progressed to land-based walking. These were all combined with transcutaneous electrical nerve stimulation (TENS) that was used consistently for up to 8 hours per day. As outcome measures, daily pain levels and walking distances were charted once the pool programme was completed (in the third phase). Phase progression was determined by shuttle test results. The pain level was correlated with the distance walked using linear regression over a 5-day average. Over a 5-day moving average, the pain level reduced and walking distance increased. The chart of recorded pain level and walking distance showed a trend toward decreased pain with the increased distance walked. In a patient undergoing multilevel lumbar fusion, the combined use of TENS and a progressive walking programme (from pool to land) reduced pain and increased walking distance. This improvement was despite poor medication compliance and a reported high level of postsurgical pain.

The aim of this study was to compare the postoperative analgesic efficacy of intra-articularly injected levobupivacaine, levobupivacaine-fentanyl, and levobupivacaine-tramadol combinations. Eighty patients scheduled for elective knee arthroscopy were divided randomly into 4 groups of 20 patients each. Group 1 (the control group) received intra-articular saline, Group 2 received levobupivacaine 2.5 mg/ml, Group 3 received levobupivacaine 2.5 mg/ml + tramadol 50 mg, and Group 4 received levobupivacaine 2.5 mg/ml + fentanyl l50 mcg. All patients were operated on under general anesthesia, and a total of 20 ml study solution was injected: 7 ml subcutaneously before surgery and 13 ml intra-articularly upon completion of surgery. For postoperative, pain visual analogue scale (VAS) was assessed at the 1st, 2nd, 4th, 8th, 12th, and 24th hours postoperatively. Patients with a VAS score over 5 received diclofenac sodium, and the need for rescue analgesics was recorded. At the 1st, 2nd, 4th, 8th, 12th, and 24th postoperative hours, Group 3 and Group 4 had statistically significant lower VAS scores of pain (p<0.01). Postoperative rescue analgesic requirements were different among the groups. The postoperative 1st hour analgesic requirement was statistically significantly lower in Group 3 and Group 4 when compared to the other groups (p<0.01). At the postoperative 2nd and 4th hours, analgesic requirements were statistically significantly lower in Group 3 than in the other groups (p<0.01). Analgesic requirements were statistically significantly lower in Group 3 and Group 4 than in the other groups (p<0.01). Analgesic requirements at the 12th and 24th postoperative hours did not show any statistically significant difference (p>0.05). The results indicated that levobupivacaine combined with either fentanyl or tramadol decreased rescue analgesic requirements when compared to levobupivacaine alone.

Dexamethasone decreases chemotherapy-induced emesis when added to antiemetic regimens. This study was designed to compare the effectiveness of granisetron and dexamethasone with granisetron alone in the prevention of post-operative vomiting after strabismus repair, tonsillectomy with or without adenoidectomy in children. In a randomized, double-blind study, 60 healthy children, 4-10 yr of age, received either granisetron 40 micrograms.kg-1 and saline (Group S) or granisetron 40 micrograms.kg-1 and dexamethasone 4 mg (Group D) iv immediately after the induction of anaesthesia. All subjects received anaesthetics consisting of sevoflurane and nitrous oxide in oxygen Postoperative pain was treated with acetaminophen pr or pentazocine iv. Postoperatively, during the first 24 hr after anaesthesia, the frequencies of retching and vomiting, and the incidence of adverse events were recorded by nursing staff. There were no differences between the treatment groups with regard to demographics, surgical procedure, anaesthetic administered or analgesics used for postoperative pain. The frequency of the symptoms was 27% and 7% in Groups S and D, respectively (P < 0.05). The incidence of adverse events was comparable in the two groups. The prophylactic administration of granisetron and dexamethasone was more effective than granisetron alone in the prevention of postoperative vomiting in paediatric subjects undergoing strabismus repair, tonsillectomy and adenoidectomy.

Rotator cuff repair often results in significant pain postoperatively, the cause of which is undetermined. Purpose/Hypothesis: The aim of this study was to evaluate the relationship between rotator cuff tear area and postoperative pain in patients who had undergone arthroscopic rotator cuff repair. We hypothesized that larger tears would be more painful because of elevated repair tension at 1 week postoperatively but that smaller tears would be more painful because of a greater healing response, especially from 6 weeks postoperatively. Cohort study; Level of evidence, 3. A total of 1624 patients who underwent arthroscopic rotator cuff repair were included in this study. Exclusion criteria were moderate to severe osteoarthritis, isolated subscapularis repair, calcific tendinitis, synthetic patch repair, revision surgery, and retears on ultrasound at 6 months after surgery. Rotator cuff tears were subdivided into groups based on the tear size and retear rate found for each group. A modified L'Insalata questionnaire was given before surgery and at 1 week, 6 weeks, 3 months, and 6 months after surgery. Pearson and Spearman correlation coefficient tests were performed between rotator cuff tear areas and pain scores. Intraoperative rotator cuff tear areas did not correlate with pain scores preoperatively or at 1 week after surgery. A smaller tear area was associated with more frequent and severe pain with overhead activities, at rest, and during sleep as well as a poorer perceived overall shoulder condition at 6 weeks, 3 months, and 6 months after repair ( r = 0.11-0.23, P < .0001). Patients who were younger, had partial-thickness tears, and had occupational injuries experienced more pain postoperatively ( r = 0.10-0.28, P < .0001). Larger tears did not have more pain at 1 week after surgery. The retear rate was 7% in tears <2 cm 2 but reached 44% in tears >8 cm 2 . There were fewer retears with smaller tears, but they were more painful than large tears postoperatively from 6 weeks to 6 months after surgery. Smaller tears may heal more vigorously, causing more pain. Patients with smaller tears experienced more pain after rotator cuff repair compared with patients with larger tears. These findings are contrary to previous ideas about tear size and postoperative pain. Healing is likely a determinant of postoperative pain.

To our knowledge, there is no evidence to support the use of local infiltration analgesia (LIA) for postoperative pain relief after periacetabular osteotomy (PAO). We investigated the effect of wound infiltration with a long-acting local anesthetic (ropivacaine) for postoperative analgesia after PAO. We performed a randomized, double-blind, placebo-controlled trial (ClinicalTrials.gov: NCT00815503) in 53 patients undergoing PAO to evaluate the effect of local anesthetic infiltration on postoperative pain and on postoperative opioid consumption. All subjects received intraoperative infiltration followed by 5 postoperative injections in 10-hour intervals through a multi-holed catheter placed at the surgical site. 26 patients received ropivacaine and 27 received saline. The intervention period was 2 days and the observational period was 4 days. All subjects received patient-controlled opioid analgesia without any restrictions on the total daily dose. Pain was assessed at specific postoperative time points and the daily opioid usage was registered. Infiltration with 75 mL (150 mg) of ropivacaine did not reduce postoperative pain or opioid requirements during the first 4 days. The clinical importance of ropivacaine as single component in postoperative treatment of pain is questionable, and we are planning further studies to explore the potential of LIA in larger volume-and also a multimodal regimen-to treat pain in this category of patients.

Management of postoperative pain after laparoscopic segmental colonic resections remains controversial. We compared 2 methods of analgesia within an Enhanced Recovery After Surgery (ERAS) program. The goal of the study was to investigate whether administration of intrathecal bupivacaine/morphine would lead to an enhanced recovery. A single-center, randomized, double-blind controlled trial was performed (NL43488.101.13). Patients scheduled for laparoscopic segmental intestinal resections were considered. Exclusion criteria were patients in whom contraindications to spinal anesthesia were present, conversion to open surgery, and gastric and rectal surgery. The intervention group received single-shot intrathecal bupivacaine/morphine (12.5 mg/300 μg), with an altered dose for older patients. The control group received a sham procedure and a bolus of piritramide (0.1 mg/kg). Both groups received standardized general anesthesia and a patient-controlled intravenous analgesia pump as postoperative analgesia. All patients were treated according to an ERAS protocol. A decrease in days to "fit for discharge" was the primary outcome. Fifty-six patients were enrolled. Intervention group patients were fit for discharge earlier (median of 3 vs 4 days, P = 0.044). Furthermore, there was a significant decrease in opioid use and lower pain scores on the first postoperative day in the intervention group. There were no differences in adverse events (except for more pruritus), time to mobilization, fluid administration, or patient satisfaction. This randomized controlled trial shows that intrathecal morphine is a more effective method of postoperative analgesia in laparoscopic surgery than intravenous opioids within an ERAS program. Recovery is faster and less painful with intrathecal morphine. Other studies have confirmed these results, although data on faster recovery are new and require confirmation in future trials. This study was registered at ClinicalTrials.gov, identifier NCT02284282.

Music and the reduction of post-operative pain.

PubMed

Dunn, Kelly

The prevention and treatment of post-operative pain, and the promotion of comfort are the challenges facing practitioners working in the recovery room setting. Surgical pain produces autonomic, psychological, immunological and behavioural responses that can delay or inhibit normal healing. Nurses spend more time with patients experiencing pain than any other healthcare professional. Therefore, they are in an ideal position to consider other pain-relieving strategies to complement the analgesics currently used. The studies reviewed cannot prove that music is effective in reducing post-operative pain, because the research methodology in the majority is poor. Patients, experience of listening to music post-operatively was positive, aiding distraction and increasing comfort. This shows the difference between inconsistent results for the objective measures of pain and what the patient is reporting.

Cold therapy used in the sports medicine settings has been found to be effective in reducing postoperative pain; however, there are limited studies that examine the effect of cold therapy on postoperative pain in patients with posterior lumbar spinal fusion. The purpose of this study was to determine the effects of cold on postoperative spine pain and add to the body of knowledge specific to practical application of cold therapy in the spine surgery setting. Researchers used a two-group randomized control design to evaluate the effects of local cold therapy on postoperative pain and analgesia use after lumbar spinal fusion surgery. The primary outcome was postoperative pain. Secondary outcomes included analgesia use and perceived benefit of cold therapy. The intervention (cold) group had a marginally greater reduction in mean Numerical Rating Scale score across all 12 pain checks (M ± SD = -1.1 ± 0.8 points reduction vs. -1.0 ± 0.8 points reduction, p = .589). On average, the intervention group used less morphine equivalents (M ± SD = 12.6 ± 31.5 vs. 23.7 ± 40.0) than the control group across pain checks seven to 12 (p = .042). This study provides additional evidence to support the use of cold therapy as an adjuvant pain management strategy to optimize pain control and reduce opioid consumption following spine fusion surgical procedures.

The cornea is the target of most surgeries for refractive disorders, as myopia. It is estimated that almost 1 million patients undergo corneal refractive surgery each year in the United States. Refractive surgery includes photorefractive keratectomy (PRK) that produces intense postoperative pain. This review presents the main pain mechanisms behind PRK-related pain and the available therapeutic options for its management. Data sources included literature of cornea anatomy, treatment of PRK postoperative pain, mechanisms of corneal pain, in 3 electronic databases: Pubmed, Scopus, and Web of Science. Only double-blinded controlled trials on pain control after PRK were selected to show the endpoints, treatment, and control strategies. A total of 18 double-blind, controlled trials were identified. These studies have shown the use of topical nonsteroidal anti-inflammatory drugs, topical steroidal anti-inflammatory drugs, systemic analgesics, cold balanced saline solution, topical anesthetic, gabapentin, and morphine to treat postoperative pain in PRK. The percentage of responders has seldom been reported, and few studies allow for the formal calculation of the number necessary to treat. Postoperative intense pain after PRK laser surgery remains the main challenge to its widespread use for the correction of refractive errors.

Gabapentin has antihyperalgesic and anxiolytic properties. We thus tested the hypothesis that premedication with gabapentin would decrease preoperative anxiety and improve postoperative analgesia and early postoperative knee mobilization in patients undergoing arthroscopic anterior cruciate ligament repair under general anesthesia. Forty patients were randomly assigned to receive 1200 mg oral gabapentin or placebo 1-2 h before surgery; anesthesia was standardized. Patients received morphine, 0.1 mg/kg, 30 min before the end of surgery and postoperatively via a patient-controlled pump. Pain scores and morphine consumption were recorded over 48 hours. Degrees of active and passive knee flexion and extension were recorded during physiotherapy on days 1 and 2. Preoperative anxiety scores were less in the Gabapentin than Control group (visual analog [VAS] score of 28 ± 16 mm versus 66 ± 15 mm; P < 0.001). The Gabapentin group required less morphine than the Control group (29 ± 22 mg versus 69 ± 40 mg; P < 0.001). VAS pain scores at rest and after mobilization were significantly reduced in the Gabapentin group. First and maximal passive and active knee flexions at 24 and 48 hours were significantly more extensive in the Gabapentin than in the Control group. In conclusion, premedication with 1200 mg gabapentin improved preoperative anxiolysis, postoperative analgesia, and early knee mobilization after arthroscopic anterior cruciate ligament repair.

Poorly controlled postoperative pain: prevalence, consequences, and prevention

This review provides an overview of the clinical issue of poorly controlled postoperative pain and therapeutic approaches that may help to address this common unresolved health-care challenge. Postoperative pain is not adequately managed in greater than 80% of patients in the US, although rates vary depending on such factors as type of surgery performed, analgesic/anesthetic intervention used, and time elapsed after surgery. Poorly controlled acute postoperative pain is associated with increased morbidity, functional and quality-of-life impairment, delayed recovery time, prolonged duration of opioid use, and higher health-care costs. In addition, the presence and intensity of acute pain during or after surgery is predictive of the development of chronic pain. More effective analgesic/anesthetic measures in the perioperative period are needed to prevent the progression to persistent pain. Although clinical findings are inconsistent, some studies of local anesthetics and nonopioid analgesics have suggested potential benefits as preventive interventions. Conventional opioids remain the standard of care for the management of acute postoperative pain; however, the risk of opioid-related adverse events can limit optimal dosing for analgesia, leading to poorly controlled acute postoperative pain. Several new opioids have been developed that modulate μ-receptor activity by selectively engaging intracellular pathways associated with analgesia and not those associated with adverse events, creating a wider therapeutic window than unselective conventional opioids. In clinical studies, oliceridine (TRV130), a novel μ-receptor G-protein pathway-selective modulator, produced rapid postoperative analgesia with reduced prevalence of adverse events versus morphine.

Background The aim of the present study was to compare clinically the incidence of postoperative pain after endodontic treatment using the Reciproc System, taking into account the operator’s experience. Material and Methods One hundred patients scheduled for routine endodontic treatment were enrolled in this study. Endodontic treatment was carried out in a single visit by undergraduate and postgraduate students. The chemomechanical preparation of root canals was performed with Reciproc instruments. Pretreatment and postoperative pain was recorded using a visual analogue scale (VAS). Postoperative pain and the need for analgesic consumption were assessed at 4, 8, 16, 24, 48 and 72 hours post-treatment. The data were analyzed using the Mann–Whitney U and Chi-Square test, and the significance was set at P<0.05. Results The mean value of pain after root canal treatment was 1.13±1.94 and 1.91±2.07 on a VAS between 0 and 10 in treatments performed by undergraduate and postgraduate students, respectively. There was a significant difference in the incidence of postoperative pain between the two groups (P<0.05). Conclusions The prevalence of postoperative pain was high in the treatments performed by postgraduate students in comparison with undergraduate students. This suggests that operator experience has an influence on the prevalence of postoperative pain after root canal treatment. Key words:Post-endodontic pain, root canal treatment, reciprocating systems, Expert operators Inexperienced operators. PMID:28828152

Postoperative nausea and vomiting (PONV) is a complication affecting between 20 and 40% of all surgery patients, with high-risk patients experiencing rates of up to 80%. Recent studies and publications have shed light on the uses of alternative treatment for PONV through their modulation of endogenous opioid neuropeptides and neurokinin ligands. In addition to reducing PONV, hypnosis was reported to be useful in attenuating postoperative pain and anxiety, and contributing to hemodynamic stability. Music therapy has been utilized to deepen the sedation level and decrease patient anxiety, antiemetic and analgesic requirements, hospital length of stay, and fatigue. Isopropyl alcohol and peppermint oil aromatherapy have both been used to reduce postoperative nausea. With correct training in traditional Chinese healing techniques, acupuncture (APu) at the P6 acupoint has also been shown to be useful in preventing early PONV, postdischarge nausea and vomiting, and alleviating of pain. Electro-acupuncture (EAPu), as with APu, provided analgesic and antiemetic effects through release and modulation of opioid neuropeptides. These non-pharmacological modalities of treatment contribute to an overall patient wellbeing, assisting in physical and emotional healing.

It has been reported that PECS II block can alleviate postoperative pain following transapical transcatheter aortic valve implantation (TA-TAVI). However, the effectiveness of continuous PECS II block with catheterization has not yet been reported on the postoperative pain in patients undergoing TA-TAVI. We experienced two cases of TA-TAVI who received PECS II block with catheterization to manage postoperative pain. In the first case, a bolus injection for intraoperative pain and subsequent catheterization were performed before the implantation. However, the patient developed severe pain postoperatively in spite of the continuous block due to displacement of the catheter. In the second case, a bolus injection and the catheterization for the continuous block were performed before and after the implantation, respectively, which provided high-quality pain control. Continuous PECS II block may be useful to control perioperative pain associated with TA-TAVI. The insertion of the catheter after the implantation could be useful to avoid its displacement during the surgery.

Abstract Postoperative pain is a frequent complication associated with root canal treatment, especially during apical instrumentation of tooth with preexisting periradicular inflammation Objectives The aim of this clinical study was to evaluate the influence of the instrumentation techniques on the incidence and intensity of postoperative pain in single-visit root canal treatment. Material and Methods Ninety patients with single root/canal and non-vital pulps were included. The patients were assigned into 3 groups according to root canal instrumentation technique used; modified step-back, reciprocal, and rotational techniques. Root canal treatment was carried out in a single visit and the severity of postoperative pain was assessed via 4-point pain intensity scale. All the participants were called through the phone at 12, 24 and 48 h to obtain the pain scores. Data were analyzed through the Kruskal–Wallis test. Results There was significant difference between all groups (p<0.05). The modified step-back technique produced postoperative pain significantly lower than the rotational (p=0.018) and reciprocal (p=0.020) techniques. No difference was found between the reciprocal and rotational techniques (p=0.868). Postoperative pain in the first 12 h period (p=0.763) and in the 24 h period (p=0.147) was not significantly different between the groups. However, the difference in the 48 h period was statistically different between the groups (p=0.040). Conclusion All instrumentation techniques caused postoperative pain. The modified step-back technique produced less pain compared to the rotational and reciprocal techniques. PMID:28198972

Pain control in augmentation mammaplasty using indwelling catheters in 687 consecutive patients: data analysis.

Postoperative pain following augmentation mammaplasty can cause significant disability. In the authors' previously published prospective study of 644 consecutive augmentation mammaplasty patients, it was shown that the use of indwelling catheters for the postoperative instillation of bupivacaine is both safe and effective in postoperative pain management. This study analyzes a large population of augmentation mammaplasty patients to not only compare the effectiveness of catheter control with systemic analgesics but also to delineate sites of pain and determine if any of a variety of factors influence postoperative pain. Questionnaires were given to all patients to record the extent of pain reduction following the instillation of local anesthesia, patient preference for a variety of analgesics, and the locations of postoperative pain. Potential correlations to pain-including the number of children, age, handedness, preoperative fear, pain tolerance, and length of narcotic use-were investigated using statistical analysis. Operative aspects, such as the size of implants, use of asymmetrical implants, intraoperative expansion, duration of surgery, and sharp versus blunt dissection were also studied to determine if these factors influenced postoperative pain. Self-administration of bupivacaine the evening after surgery achieved pain reduction in 89% of patients. Patients gave high preference scores for the instillation of local anesthesia, comparable to rates achieved with the systemic narcotics Vicodin (Abbott Laboratories, Abbott Park, IL) and Percocet (Endo Pharmaceuticals, Chadds Ford, PA). Lower patient ratings were given to ibuprofen and methocarbamol. Patients identified multiple sites of postoperative pain, including the sternum, armpits, outer ribs, top of the breast (infraclavicular), interscapular region, and shoulders. Older patients experienced less pain. Patients who reported more pain, higher levels of fear, and sternal pain used narcotics for a longer period of time. Duration of surgery, blunt versus sharp dissection, and intraoperative expansion were not significantly related to pain. Combined implant size did not correlate with pain, though in the case of asymmetrical implants, greater pain (not statistically significant) on the larger side was reported. Postoperative pain following augmentation mammaplasty may be influenced by several factors, but these appear unrelated to implant size, specific operative techniques (blunt versus sharp dissection), or duration of surgery. Pain may involve not only the breasts, but also the sternum, sides of the chest, armpits, and infraclavicular and interscapular areas. The use of indwelling catheters for the instillation of a long-acting anesthetic is rated comparable in efficacy to the systemic narcotics Vicodin and Percocet. Sternal pain can be severe and may require narcotics for effective pain control.

Abstract The aim of this study was to identify clinical risk factors for unfavorable pain trajectories after breast cancer surgery, to better understand the association between pain expectation, psychological distress, and acute postoperative pain. This prospective study included 563 women treated for breast cancer. Psychological data included questionnaires for depressive symptoms and anxiety. Experimental pain tests for heat and cold were performed before surgery. The amount of oxycodone needed for satisfactory pain relief after surgery was recorded. Pain intensity in the area of operation before surgery and during the first postoperative week and expected intensity of postoperative pain were recorded using the Numerical Rating Scale (NRS 0-10). Pain trajectories were formed to describe both initial intensity (the intercept) and the direction of the pain path (the slope). Factors associated with higher initial pain intensity (the intercept) were the amount of oxycodone needed for adequate analgesia, psychological distress, type of axillary surgery, preoperative pain in the area of the operation, and expectation of postoperative pain. The higher the pain initially was, the faster it resolved over the week. Expectation of severe postoperative pain was associated with higher scores of both experimental and clinical pain intensity and psychological factors. The results confirm that acute pain after breast cancer surgery is a multidimensional phenomenon. Psychological distress, pain expectation, and the patients' report of preoperative pain in the area to be operated should be recognized before surgery. Patients having axillary clearance need more efficient analgesic approaches. PMID:28134654

Pain locations in the postoperative period after cardiac surgery: Chronology of pain and response to treatment.

PubMed

Roca, J; Valero, R; Gomar, C

Postoperative pain after cardiac surgery (CS) can be generated at several foci besides the sternotomy. Prospective descriptive longitudinal study on the chronological evolution of pain in 11 sites after CS including consecutive patients submitted to elective CS through sternotomy. The primary endpoints were to establish the main origins of pain, and to describe its chronological evolution during the first postoperative week. Secondary endpoints were to describe pain characteristics in the sternotomy area and to correlate pain intensity with other variables. Numerical Pain Rating Scale from 0 to 10 at rest and at movement on postoperative days 1, 2, 4 and 6. Numerical Pain Rating Scale>3 was considered moderate pain. Statistical analysis consisted in Mann-Whitney U-test, a Chi-squared, a Fisher exact text and Pearson's correlations. Forty-seven patients were enrolled. In 4 of 11 locations pain was reported as Numerical Pain Rating Scale>3 (sternotomy, oropharynx, saphenectomy and musculoskeletal pain in the back and shoulders). Maximum intensity of pain on postoperative days 1 and 2 was reported in the sternotomy area, while on postoperative days 4 and 6 it was reported at the saphenectomy. Pain at rest and at movement differed considerably in the sternotomy, saphenectomy and oropharynx. Pain at back and shoulders and at central venous catheter entry were not influenced by movement. Pain in the sternotomy was mainly described as oppressive. Patients with arthrosis and younger patients presented higher intensity of pain (P=.004; P=.049, respectively). Four locations were identified as the main sources of pain after CS: sternotomy, oropharynx, saphenectomy, and back and shoulders. Pain in different focuses presented differences in chronologic evolution and was differently influenced by movement.

Dexmedetomidine, α 2 -adrenergic agonist, when coadministered with local anesthetics, improves the speed of onset, duration of analgesia and decreases the dose of local anesthetic used. The aim of this study was to compare the efficacy of local subcutaneous wound infiltration of ropivacaine alone with ropivacaine plus dexmedetomidine for postoperative pain relief following lower segment cesarean section (LSCS). The study was a prospective, randomized control, double-blind study. Sixty female patients belonging to physical status American Society of Anesthesiologists Grade I or II scheduled for LSCS under spinal anesthesia were randomly allocated into two groups of thirty patients each. Group A: local subcutaneous wound infiltration of 0.75% ropivacaine (3 mg/kg) diluted with normal saline to 40 ml. Group B: local subcutaneous wound infiltration of 0.75% ropivacaine (3 mg/kg) plus dexmedetomidine (1.5 μg/kg) of the body weight diluted with normal saline to 40 ml. Standard spinal anesthesia technique was used and LSCS was conducted. The allocated drug was administered by local subcutaneous wound infiltration before closure of the skin. In postoperative period, pain was assessed using visual analog scale (VAS) over a period of 24 h, time of giving first rescue analgesic consumption, mean analgesic consumption, patient satisfaction, and incidence of side effects in 24 h postoperative period was noted. All observations were tabulated and statistically analyzed using Chi-square test and unpaired t -test. A total number of patients requiring rescue analgesic, mean VAS each time rescue analgesic was given, and the mean analgesic required in 24 h postoperative period was lesser in Group B than in Group A. Dexmedetomidine added to ropivacaine for the surgical wound infiltration significantly reduces postoperative pain and rescue analgesic consumption in patients undergoing LSCS. No serious adverse effects were noted.

Medical studies have shown some potential for infiltrations of liposomal bupivacaine (Exparel; Pacira Pharmaceuticals, San Diego, CA), a slow-release bupivacaine solution, to extend postoperative benefits of numbness/pain relief for up to several days. Because the Food and Drug Administration has approved Exparel only for infiltrations, we wanted to evaluate if it would be effective as an infiltration to control postoperative pain. The purpose of this study was to compare an infiltration of bupivacaine with liposomal bupivacaine for postoperative numbness and pain in symptomatic patients diagnosed with pulpal necrosis experiencing moderate to severe preoperative pain. One hundred patients randomly received a 4.0-mL buccal infiltration of either bupivacaine or liposomal bupivacaine after endodontic debridement. For postoperative pain, patients were given ibuprofen/acetaminophen, and they could receive narcotic pain medication as an escape. Patients recorded their level of numbness, pain, and medication use the night of the appointment and over the next 5 days. Success was defined as no or mild postoperative pain and no narcotic use. The success rate was 29% for the liposomal group and 22% for the bupivacaine group, with no significant difference (P = .4684) between the groups. Liposomal bupivacaine had some effect on soft tissue numbness, pain, and use of non-narcotic medications, but it was not clinically significant. There was no significant difference in the need for escape medication. For symptomatic patients diagnosed with pulpal necrosis experiencing moderate to severe preoperative pain, a 4.0-mL infiltration of liposomal bupivacaine did not result in a statistically significant increase in postoperative success compared with an infiltration of 4.0 mL bupivacaine.

Mobile phone messaging software robots allow clinicians and healthcare systems to communicate with patients without the need for human intervention. The purpose of this study was to (1) describe a method for communicating with patients postoperatively outside of the traditional healthcare setting by utilizing an automated software and mobile phone messaging platform and to (2) evaluate the first week of postoperative pain and opioid use after common ambulatory hand surgery procedures. The investigation was a prospective, multicenter investigation of patient-reported pain and opioid usage after ambulatory hand surgery. Inclusion criteria included any adult with a mobile phone capable of text messaging, who was undergoing a common ambulatory hand surgical procedure at one of three tertiary care institutions. Participants received daily, automated text messages inquiring about their pain level and how many tablets of prescription pain medication they had taken in the past 24 h. Initial 1-week response rate was assessed and compared between different patient demographics. Patient-reported pain and opioid use were also quantified for the first postoperative week. Statistical significance was set as p < 0.05. Forty-seven (n = 47) patients were enrolled in this investigation. Total response rate of both pain and opioid medication questions through 7 days was 88.3%. Pain trended down on a daily basis for the first postoperative week, with the highest levels of pain being reported in the first 48 h after surgery. Patients reported an average use of 15.9 ± 14.8 tablets of prescription opioid pain medication. We find that a mobile phone messaging software robot allows for effective data collection of postoperative pain and pain medication use. Patients undergoing common ambulatory hand procedures utilized an average of 16 tablets of opioid medication in the first postoperative week.

Objectives Fibromyalgia characteristics can be evaluated using a simple, self-reported measure, which correlates with postoperative opioid consumption following lower-extremity joint arthroplasty. The purpose of this study was to determine if preoperative pain history and/or the fibromyalgia survey score can predict postoperative outcomes following shoulder arthroscopy, which may cause moderate-to-severe pain. Methods In this prospective study, 100 shoulder arthroscopy patients completed preoperative validated self-report measures to assess baseline quality of recovery score, physical functioning, depression/anxiety, and neuropathic pain. Fibromyalgia characteristics were evaluated using a validated measure of widespread pain and comorbid symptoms on a 0–31 scale. Outcomes were assessed on postoperative days 2 (opioid consumption [primary], pain, physical functioning, quality of recovery score) and 14 (opioid consumption, pain). Results Fibromyalgia survey scores ranged from 0–13. The cohort was divided into tertiles for univariate analyses. Preoperative depression/anxiety (p<0.001) and neuropathic pain (p=0.008) were higher, and physical functioning was lower (p<0.001), in higher fibromyalgia survey score groups. The fibromyalgia survey score was not associated with postoperative pain or opioid consumption; however, it was independently associated with poorer quality of recovery scores (p=0.001). The only independent predictor of postoperative opioid use was preoperative opioid use (p=0.038). Discussion Fibromyalgia survey scores were lower than those in a previous study of joint arthroplasty. Although they distinguished a negative preoperative pain phenotype, fibromyalgia scores were not independently associated with postoperative opioid consumption. Further research is needed to elucidate the impact of a fibromyalgia-like phenotype on postoperative analgesic outcomes. PMID:26626295

Comparison of pain and swelling after removal of oral leukoplakia with CO2 laser and cold knife: A randomized clinical trial

Objective: The aim of this study was to compare conventional surgery with carbon dioxide (CO2) laser in patients with oral leukoplakia, and to evaluate the postoperative pain and swelling. Study design: A total of 48 patients (27 males and 21 females) with a mean age of 53.7 ± 11.7 years and diagnosed with oral leukoplakia were randomly assigned to receive treatment either with conventional surgery using a cold knife or with a CO2 laser technique. A visual analog scale (VAS) was used to score pain and swelling at different postoperative time points. Results: Pain and swelling reported by the patients was greater with the conventional cold knife than with the CO2 laser, statistically significant differences for pain and swelling were observed between the two techniques during the first three days after surgery. Followed by a gradual decrease over one week. In neither group was granuloma formation observed, and none of the patients showed malignant transformation during the period of follow-up. Conclusions: The CO2 laser causes only minimal pain and swelling, thus suggesting that it may be an alternative method to conventional surgery in treating patients with oral leukoplakia. Key words:Oral leukoplakia, treatment, laser surgery, cold knife, pain, swelling. PMID:23229239

Intractable cervical radiculopathy secondary to stenosis or herniated nucleus pulposus is commonly treated with an anterior cervical decompression and fusion (ACDF) procedure. However, there is little evidence in the literature that demonstrates the impact such surgery has on long-term range of motion (ROM) outcomes. The objective of this study was to compare cervical ROM and patient-reported outcomes in patients before and after a 1, 2, or 3 level ACDF. Prospective, nonexperimental. Forty-six patients. The following were measured preoperatively and also at 3 and 6 months after ACDF: active ROM (full and painfree) in three planes (ie, sagittal, coronal, and horizontal), pain visual analog scale, Neck Disability Index, and headache frequency. Patients undergoing an ACDF for cervical radiculopathy had their cervical ROM measured preoperatively and also at 3 and 6 months after the procedure. Neck Disability Index and pain visual analog scale values were also recorded at the same time. Both painfree and full active ROM did not change significantly from the preoperative measurement to the 3-month postoperative measurement (ps>.05); however, painfree and full active ROM did increase significantly in all three planes of motion from the preoperative measurement to the 6-month postoperative measurement regardless of the number of levels fused (ps≤.023). Visual analog scale, Neck Disability Index, and headache frequency all improved significantly over time (ps≤.017). Our results suggest that patients who have had an ACDF for cervical radiculopathy will experience improved ROM 6 months postoperatively. In addition, patients can expect a decrease in pain, an improvement in neck function, and a decrease in headache frequency. Copyright © 2013 Elsevier Inc. All rights reserved.

The study was conducted to evaluate the effect of perioperative ketorolac on pain associated with first-trimester aspiration abortion. A double-blind, randomized, placebo-controlled trial was performed involving pregnant women up to 14 weeks' gestation who desired pregnancy termination. Subjects were randomized to receive ketorolac 30 mg intravenously (n=31) or placebo (n=45) at the time of induction of anesthesia. Postoperative pain was assessed using a visual analog scale (VAS). The primary outcome was pain control as determined by VAS score. Secondary measures of patient use of supplemental postoperative pain medications and patient satisfaction were assessed. Subjects in the ketorolac group had lower postoperative pain scores on the VAS at all time points compared to the placebo group, but the difference was not statistically significant. The ketorolac group used less postoperative acetaminophen compared to the placebo group (6.5% versus 35.6%), respectively. Subjects in the placebo group and the ketorolac group had similar requirements for postoperative narcotics in the recovery room (22.2% versus 19.4%). Patient satisfaction with pain level was equivalent between the groups at all postoperative end points. There was no observed difference in perioperative blood loss observed between the two groups. Perioperative ketorolac has the same effect on postoperative pain as determined by VAS as placebo. The use of ketorolac at the 30-mg dose cannot be recommended for better pain control for patients undergoing first-trimester pregnancy termination by suction curettage. The only positive effect of the use of ketorolac compared to placebo was a reduction in the use of acetaminophen. Ketorolac use does not appear to change blood loss in the operating room or through postoperative day 1 compared to placebo. Copyright © 2012 Elsevier Inc. All rights reserved.

Objective The aim of this study was to evaluate the management of postoperative pain at the Niamey National Hospital. Methods A prospective study was conducted in the Department of Anesthesiology and Intensive Care at the Niamey National Hospital from March to June, 2009. Data collected included age, sex, literacy, American Society of Anesthesiologists (ASA) physical status classification, type of anesthesia, type of surgery, postoperative analgesics used, and the cost of analgesics. Three types of pain assessment scale were used depending on the patient’s ability to describe his or her pain: the verbal rating scale (VRS), the numerical rating scale (NRS), or the visual analog scale (VAS). Patients were evaluated during the first 48 hours following surgery. Results The sample included 553 patients. The VRS was used for the evaluation of 72% of patients, the NRS for 14.4%, and the VAS for 13.6%. Of the VRS group, 33.9%, 8.3%, and 2.1% rated their pain as 3 or 4 out of 4 at 12, 24, and 48 hours postoperatively, respectively. For the NRS group, 33.8%, 8.8%, and 2.5% rated their pain as greater than 7 out of 10 at 12, 24, and 48 hours postoperatively, respectively. For the VAS group, 29.3%, 5.4%, and 0% rated their pain as greater than 7 out of 10 at 12, 24, and 48 hours postoperatively, respectively. Conclusion Postoperative pain assessment and management in developing countries has not been well described. Poverty, illiteracy, and inadequate training of physicians and other health personnel contribute to the underutilization of postoperative analgesia. Analysis of the results gathered at the Niamey National Hospital gives baseline data that can be the impetus to increase training in pain management and to establish standardized protocols.

Polyamines have been identified as pain agonists and interact with N-methyl-D-aspartate receptors. A prospective, randomized, multicenter, and blinded phase II clinical trial was conducted to evaluate a polyamine-deficient diet for the treatment of perioperative pain in patients during spinal surgery. All analyses followed the intention-to-treat principle. The trial was designed to evaluate the dose-ranging effect of a low polyamine diet with respect to a total (group 1) or partial (group 2) polyamine diet on perioperative pain (7 d before and 5 d after surgery). Pain (numerical scale at rest and motion), quality of life questionnaires (Brief Pain Inventory, EIFEL questionnaire, and Short Form-12 acute questionnaire), and tolerance of and compliance with the nutritional program were measured. Compliance (preoperatively: 100% in group 1 and 83% in group 2; postoperatively: 83% in group 1 and 71% in group 2) and tolerance were good. After 7 d following the diet before surgery, decreased pain was observed in group 1 whereas no effect was observed in group 2 (P = 0.144). This analgesic effect became significant in group 1 in the subgroup of patients with initial high levels of pain (NS ≥ 4) at rest (P = 0.03) and during motion (P = 0.011). Quality of life was significantly improved in group 1 (P = 0.0465). In the postoperative period, pain was significantly decreased in group 1 compared to group 2 at rest (P = 0.022) and during motion (P = 0.029). The effect was significantly better on patients with higher initial pain both at rest (P = 0.013) and during motion (P = 0.005) in group 1 compared to group 2. Suppression of polyamines from the diet offers a nutrition-based treatment option for perioperative pain reduction independent of and complementary to typical analgesic approaches.

Anesthesiologists use various medications to provide surgical patients with pain relief in the postoperative period. Other modalities, such as music, could be used in conjunction with opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) to decrease pain and lower heart rate and blood pressure. Our hypothesis was that patients listening to jazz in a postanesthesia care unit (PACU) would have lower heart rates and blood pressures and reduced pain and anxiety. The study objective was to determine if listening to jazz music in the PACU, when compared to wearing noise-canceling headphones with no music playing, would decrease heart rate, blood pressure, pain, or anxiety in patients undergoing a hysterectomy. The research design was a prospective, randomized study. The study was conducted in the PACU at the Penn State Hershey Medical Center in Hershey, PA, USA. A total of 56 patients, aged 18-75 y, who were categorized as status 1 or 2 according to the American Society of Anesthesiologists (ASA) Physical Status Classification System, and who were undergoing elective laparoscopic or abdominal hysterectomies, were enrolled in the study. Patients were randomly assigned either to listen to jazz music where the beats per min (BPM) was <100 (experimental group, n = 28) or to wear noise-canceling headphones (control group, n = 28) for 30 min while in the PACU after their surgery. Heart rate was the primary outcome, and secondary outcomes included systolic and diastolic blood pressure, an anxiety score, and a pain score. All outcome measures were initially recorded at baseline upon the patient's arrival in the PACU. Heart rate and blood pressure were recorded postoperatively every 5 min for the initial 30 min that a patient was in the PACU. Pain was checked every 10 min during the 30-min period; anxiety was checked at 30 min. Heart rates of patients in the noise-cancellation group were significantly lower when compared with baseline (P < .05), at all time points. For patients in the jazz group, heart rates were significantly lower at 15, 20, 25, and 30 min when compared with baseline. The pain scores were significantly lower (P < .05) in the noise-cancellation group compared with the jazz group at 10 min into the recovery period. Overall, the results showed that patients responded not only to music but also to silence in the PACU. Using music and/or noise reduction could decrease opioid administration, promote relaxation, and improve patient satisfaction.

To evaluate the analgesic efficacy of Yamamoto New Scalp Acupuncture (YNSA) as an adjuvant for postoperative pain management in cats. Prospective, randomized, blinded, clinical study. Twenty cats aged (mean ± standard deviation) 25 ± 9 months and weighing 2.7 ± 0.6 kg undergoing ovariohysterectomy. The cats were sedated with intramuscular (IM) ketamine (5 mg kg -1 ), midazolam (0.5 mg kg -1 ) and tramadol (2 mg kg -1 ). The cats were randomly distributed before induction of anesthesia into two groups of 10 cats each: group YNSA, in which bilateral basic D points were stimulated with a dry needle from 20 minutes prior to anesthetic induction to the end of the surgery; group Control, in which no acupuncture was applied. Postoperative analgesia was assessed at 1, 2, 4, 8, 12, 18 and 24 hours postextubation using an Interactive Visual Analog Scale and Universidade Estadual Paulista-Botucatu Multidimensional Composite Pain Scale (UNESP-Botucatu MCPS). Rescue analgesia was provided with IM tramadol (2 mg kg -1 ), and the pain scores were reassessed 30 minutes after rescue intervention. If the analgesia remained insufficient, meloxicam (0.2 mg kg -1 as a single dose) was administered IM. Data were analyzed using Student t-test, Fisher exact test, Mann-Whitney U test and Friedman test (p < 0.05). Significantly lower pain scores were observed in YNSA when compared with Control at 1-4 hours based on the UNESP-Botucatu MCPS scores. Although significant differences were not identified between groups requiring rescue analgesia, additional postoperative analgesia was administered to four of 10 cats in Control and no cats in YNSA. Perioperative YNSA resulted in decreased pain scores and a reduction in postoperative requirement for rescue analgesia in cats. This method should be considered a viable option as an adjuvant analgesic therapy for cats undergoing ovariohysterectomy.

Postoperative pain should be aggressively treated to decrease the development of chronic postsurgical pain. There has been an increase in the use of Human Patient Simulator (HPS) for teaching advanced courses in pharmacology to medical students, residents, and nurses. The aim of this educational investigation was to pilot the HPS for the training of medical students and surgical recovery room staff nurses in the pharmacology of opioids for the management of postoperative pain. The computerized HPS mannequin is fully monitored with appropriate displays and includes a voice speaker mounted in the head. Medical students and Postanesthesia care unit nurses, led by faculty in the Department of Anesthesiology in small groups of 4-6, participated in a 2- to 3-hour HPS course on the use of opioids for the management of acute postoperative pain. Trainees were asked to treat the acute and severe postoperative pain of a simulated patient. Opioid effects and side effects (such as respiratory depression) were presented on the mannequin in real time to the participants. Side effects of naloxone to reverse opioid depression were presented as a crisis in real time to the participants. Participants completed a 10-item course evaluation using a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree). Twenty-two nurses and nine medical students completed the HPS opioid pharmacology scenario. Almost all participants rated the HPS course very highly and rated every item as either agree or strongly agree. Most participants agreed that the simulator session improved their understanding of opioid pharmacology including opioid side effects and management of opioid complications. Course participants felt most strongly (median, interquartile range) that the simulator session improved their understanding of naloxone pharmacology (5, 0), simulators serve as a useful teaching tool (5, 0), and that they would be pleased to participate in any additional HPS teaching sessions (5, 0). The HPS provides a novel educational format to teach essential information regarding opioid pharmacology for the management of acute postoperative pain. The HPS provides a realistic format to teach the pharmacology of acute opioid side effects and the management of acute and life-threatening side effects of naloxone therapy.

General anesthesia has been widely used in pediatric dentistry in recent years. However, there remain concerns about potential postoperative dental morbidity. The goal of this study was to identify the frequency of postoperative dental morbidity and factors associated with such morbidity in children. From March 2012 to February 2013, physically and mentally healthy children receiving dental treatment under general anesthesia at the Department of Pediatric Dentistry of the Chang Gung Memorial Hospital in Taiwan were recruited. This was a prospective and observational study with different time evaluations based on structured questionnaires and interviews. Information on the patient demographics, anesthesia and dental treatment performed, and postoperative dental morbidity was collected and analyzed. Correlations between the study variables and postoperative morbidity were analyzed based on the Pearson's chi-square test. Correlations between the study variables and the scale of postoperative dental pain were analyzed using the Mann-Whitney U test. Fifty-six pediatric patients participated in this study, with an average age of 3.34 ± 1.66 years (ranging from 1 to 8 years). Eighty-two percent of study participants reported postoperative dental pain, and 23% experienced postoperative dental bleeding. Both dental pain and bleeding subsided 3 days after the surgery. Dental pain was significantly associated with the total number of teeth treated, while dental bleeding, with the presence of teeth extracted. Patients' gender, age, preoperative dental pain, ASA classification, anesthesia time, and duration of the operation were not associated with postoperative dental morbidity. Dental pain was a more common postoperative dental morbidity than bleeding. The periods when parents reported more pain in their children were the day of the operation (immediately after the procedure) followed by 1 day and 3 days after the treatment.

The benefits of regional anesthesia for surgical procedures, when compared with general anesthesia and/or systemic analgesia, include improved postoperative analgesia, an associated decrease in postoperative pain medication use, decreased nausea and vomiting, and quicker recovery and discharge from the hospital. Neurologic complications associated with regional anesthesia are extremely rare. Although rare, these complications may be reduced with new regional techniques such as the use of ultrasound or fluoroscopy, but further detailed research is needed. In regional anesthesia, rare but serious complications make it necessary to always consider the risk-benefit ratio. The articles discuss these issues and give advice on its effective and safe conduct.

Approximately 50 million US patients undergo ambulatory surgery annually. Postoperative opioid overprescribing is problematic, yet many patients report inadequate pain relief. In major inpatient surgery, intraoperative single-dose methadone produces better analgesia and reduces opioid use compared with conventional repeated dosing of short-duration opioids. This investigation tested the hypothesis that in same-day ambulatory surgery, intraoperative methadone, compared with short-duration opioids, reduces opioid consumption and pain, and determined an effective intraoperative induction dose of methadone for same-day ambulatory surgery. A double-blind, dose-escalation protocol randomized 60 patients (2:1) to intraoperative single-dose intravenous methadone (initially 0.1 then 0.15 mg/kg ideal body weight) or conventional as-needed dosing of short-duration opioids (eg, fentanyl, hydromorphone; controls). Intraoperative and postoperative opioid consumption, pain, and opioid side effects were assessed before discharge. Patient home diaries recorded pain, opioid use, and opioid side effects daily for 30 days postoperatively. Primary outcome was in-hospital (intraoperative and postoperative) opioid use. Secondary outcomes were 30 days opioid consumption, pain intensity, and opioid side effects. Median (interquartile range) methadone doses were 6 (5-6) and 9 (8-9) mg in the 0.1 and 0.15 mg/kg methadone groups, respectively. Total opioid consumption (morphine equivalents) in the postanesthesia care unit was significantly less compared with controls (9.3 mg, 1.3-11.0) in subjects receiving 0.15 mg/kg methadone (0.1 mg, 0.1-3.3; P < .001) but not 0.1 mg/kg methadone (5.0 mg, 3.3-8.1; P = .60). Dose-escalation ended at 0.15 mg/kg methadone. Total in-hospital nonmethadone opioid use after short-duration opioid, 0.1 mg/kg methadone, and 0.15 mg/kg methadone was 35.3 (25.0-44.0), 7.1 (3.7-10.0), and 3.3 (0.1-5.8) mg morphine equivalents, respectively (P < .001 for both versus control). In-hospital pain scores and side effects were not different between groups. In the 30 days after discharge, patients who received methadone 0.15 mg/kg had less pain at rest (P = .02) and used fewer opioid pills than controls (P < .0001), whereas patients who received 0.1 mg/kg had no difference in pain at rest (P = .69) and opioid use compared to controls (P = .08). In same-day discharge surgery, this pilot study identified a single intraoperative dose of methadone (0.15 mg/kg ideal body weight), which decreased intraoperative and postoperative opioid requirements and postoperative pain, compared with conventional intermittent short-duration opioids, with similar side effects.

Abdominal surgical procedures increase pulmonary complication risks. The aim of this study was to evaluate the effectiveness of chest physiotherapy during the immediate postoperative period among patients undergoing elective upper abdominal surgery. This randomized clinical trial was performed in the post-anesthesia care unit of a public university hospital. Thirty-one adults were randomly assigned to control (n = 16) and chest physiotherapy (n = 15) groups. Spirometry, pulse oximetry and anamneses were performed preoperatively and on the second postoperative day. A visual pain scale was applied on the second postoperative day, before and after chest physiotherapy. The chest physiotherapy group received treatment at the post-anesthesia care unit, while the controls did not. Surgery duration, length of hospital stay and postoperative pulmonary complications were gathered from patients' medical records. The control and chest physiotherapy groups presented decreased spirometry values after surgery but without any difference between them (forced vital capacity from 83.5 +/- 17.1% to 62.7 +/- 16.9% and from 95.7 +/- 18.9% to 79.0 +/- 26.9%, respectively). In contrast, the chest physiotherapy group presented improved oxygen-hemoglobin saturation after chest physiotherapy during the immediate postoperative period (p < 0.03) that did not last until the second postoperative day. The medical record data were similar between groups. Chest physiotherapy during the immediate postoperative period following upper abdominal surgery was effective for improving oxygen-hemoglobin saturation without increased abdominal pain. Breathing exercises could be adopted at post-anesthesia care units with benefits for patients.

Robot-assisted laparoscopic prostatectomy (RALP) is minimally invasive surgery, but also causes moderate to severe pain during the immediate postoperative period. We evaluated the efficacy and safety of intrathecal morphine (ITM) for postoperative pain control in patients undergoing RALP. Thirty patients scheduled for RALP were randomly assigned into one of two groups. In the ITM group (n = 15), postoperative pain was managed using 300 µg intrathecal morphine with intravenous patient-controlled analgesia (IV-PCA). In the IV-PCA group (n = 15), only intravenous patient-controlled analgesia was used. The numerical pain score (NPS; 0 = no pain, 100 = worst pain imaginable), postoperative IV-PCA requirements and opioid-related complications including nausea, vomiting, dizziness, headache and pruritus were compared between the two groups. The NPSs on coughing were 20 (IQR 10-50) in the ITM group and 60 (IQR 40-80) in the IV-PCA group at postoperative 24 h (p = 0.001). The NPSs were significantly lower in the ITM group up to postoperative 24 h. The ITM group showed less morphine consumption at postoperative 24 h in the ITM group than in the IV-PCA group [5 (IQR 3-15) mg vs 17 (IQR 11-24) mg, p = 0.001]. Complications associated with morphine were comparable between the two groups and respiratory depression was not reported in either group. Intrathecal morphine provided more satisfactory analgesia without serious complications during the early postoperative period in patients undergoing RALP.

The purpose of the study was to evaluate the effects of intracanal, intraoral, and extraoral cryotherapy on postoperative pain in molar teeth with symptomatic apical periodontitis. A total of 100 patients were randomly distributed into 4 groups: control (without cryotherapy application), intracanal cryotherapy application, intraoral cryotherapy application, and extraoral cryotherapy application. The postoperative pain of the patients was recorded at the first, third, fifth, and seventh days. The data were statistically analyzed by using linear regression, χ 2 , one-way analysis of variance, Tukey post hoc, and Kruskal-Wallis H tests (P = .05). There were no statistically significant differences among the groups in terms of demographic data (P > .05). The preoperative pain levels and preoperative visual analogue scale (VAS) scores of pain on percussion were similar among the groups (P > .05). The linear regression analysis demonstrated that group variable had the most significant effect on postoperative pain at day 1 (P < .001) among the other variables (group, age, gender, tooth number, preoperative pain levels, and VAS scores of pain on percussion). When compared with the control group, all the cryotherapy groups exhibited less percussion pain and less postoperative pain at the first, third, fifth, and seventh days (P < .05). Within the study limitations, all the cryotherapy applications (intracanal, intraoral, and extraoral) resulted in lower postoperative pain levels and lower VAS scores of pain on percussion versus those of the control group.

The purpose of this prospective, randomized, blinded study was to compare injection pain and postoperative pain of an apical primary X-Tip intraosseous technique to a coronal primary Stabident intraosseous technique in mandibular first molars. Using a repeated-measures design, 41 subjects randomly received 2 primary intraosseous injections at 2 separate appointments. Using a site distal to the mandibular first molar for both injections, the subjects received 1.8 mL of 2% lidocaine with 1: 100,000 epinephrine administered with the X-Tip system using an apical location in alveolar mucosa or 1.8 mL of 2% lidocaine with 1: 100,000 epinephrine administered with the Stabident system using a coronal location in attached gingiva. The pain of infiltration, perforation, needle insertion, solution deposition, mock or actual guide sleeve removal and postoperative pain were recorded on a Heft-Parker visual analogue scale (VAS) scale for the 2 intraosseous systems. The results demonstrated that the apical primary X-Tip intraosseous technique was not statistically different (P > .05) from the coronal primary Stabident technique regarding pain ratings of infiltration, perforation, needle insertion, solution deposition, mock or actual guide sleeve removal and postoperative pain (at the time subjective anesthesia wore off). However, on postoperative days 1 through 3, significantly (P < .05) more males experienced postoperative pain with the X-Tip system than with the Stabident system.

Multiple factors have been implicated in determining why certain patients have increased postoperative pain, with the potential to develop chronic pain. The purpose of this study was to: 1) identify and describe genes that affect postoperative pain perception and control; 2) address modifiable risk factors that result in epigenetic altered responses to pain; and 3) characterize differences in pain sensitivity and thresholds between opioid-naïve and opioid-dependent patients. Three electronic databases were used to conduct the literature search: Pubmed, EBSCO host, and SCOPUS. A total of 372 abstracts were reviewed, of which 46 studies were deemed relevant and are included in this review. Specific gene alterations that were shown to affect postoperative pain control included single nucleotide polymorphisms in the mu, kappa, and delta opioid receptors, ion channel genes, cytotoxic T-cells, glutamate receptors and cytokine genes, among others. Alcoholism, obesity, and smoking were all linked with genetic polymorphisms that altered pain sensitivity. Opioid abuse was found to be associated with a poorer response to analgesics postoperatively, as well as a risk for prescription overdose. Although pain perception has multiple complex influences, the greatest variability seen in response to opioids among postoperative patients known to date can be traced to genetic differences in opioid metabolism. Further study is needed to determine the clinical significance of these genetic associations.

Multicentre evaluation of postoperative pain control after 24hours in three hospitals of Colombia.

Machado-Alba, Jorge Enrique; Machado-Duque, Manuel Enrique; Ramírez-Sarmiento, Javier Orlando

To determine the intensity of pain in operated patients using a visual analogue scale and identify variables associated with lack of pain control in three cities in Colombia. A cross-sectional study in patients over the age of 18 years, between January 1 st and September 30 th 2014, in 3 clinics in Colombia. The intensity of postoperative pain using a visual analogue scale at 24hours after surgery was recorded. Socio-demographic, clinical and pharmacological variables were taken into account. SPSS 22.0 was used for the analysis. 460 patients were evaluated, mean age 47.6±17.4 years, and 63.3% were female. The mean pain level was 23.8±17.4mm, with 91 (19.8% of patients) with moderate or greater pain (i.e., lack of pain control). Tramadol was the most used analgesic, followed by dipyrone and diclofenac. 53.0% were treated with monotherapy. Compliance with the dosing regimen of the first analgesic (OR: 0.53; 95% CI: 0.294 to .988; p=.046) was statistically significantly associated with a decreased risk of poorly controlled pain. Pain intensity and the proportion of patients with uncontrolled pain at 24hours after surgery show better results than other studies previously published in the country. There must be insistence on the administration of analgesia within a suitable interval in order to improve pain control. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Our purposes were to determine the influence of psychological profile on hemodynamic changes in patients who undergo surgical removal of the third molars under intravenous sedation and to evaluate the effect on patients' anxiety and postoperative recovery. We performed a prospective study of 100 patients (American Society of Anesthesiologists classes I and II; aged ≥18 years) seen in the CIMIVClinic (Department of Oral Surgery, Casa de Salud University Hospital, Valencia, Spain) who underwent extractions of all third molars under intravenous sedation. All patients were administered the Symptom Checklist 90 Revised (SCL-90-R). The following parameters were monitored at different times during the surgical interventions: systolic blood pressure, diastolic blood pressure, oxygen saturation, and heart rate. Position and depth of impaction of the tooth (Pell and Gregory classification and Winter classification), surgery duration, and surgical technique also were recorded. Finally, the degree of pain experienced the week after the surgical intervention was measured using a visual analog scale. Patients' anxiety levels preoperatively were significantly higher in patients with psychological distress (P = .023). Postoperative pain significantly decreased from the first day to the seventh day in healthy patients but not in patients with altered psychological conditions (P < .05). Nevertheless, the hemodynamic changes were not correlated with the psychological impairment. Intravenous sedation enables the control of hemodynamic changes in all patients independently of their psychological profile. Patients with psychological distress present with higher levels of dental anxiety and postoperative pain. Future studies are needed to further clarify this interaction.

Calcified rotator cuff tendinitis is a common cause of chronic shoulder pain that leads to significant pain and functional limitations. Although most patients respond well to conservative treatment, some eventually require surgical treatment. To evaluate the clinical outcome with arthroscopic removal of calcific deposit and rotator cuff repair without acromioplasty for the treatment of calcific tendinitis of the supraspinatus tendon. Case series; Level of evidence, 4. This study retrospectively evaluated 30 consecutive patients with a mean age of 49.2 years. The mean follow-up was 35 months (range, 24-88 months). Pre- and postoperative functional assessment was performed using the Constant score, University of California Los Angeles (UCLA) score, and Quick Disabilities of the Arm, Shoulder, and Hand (DASH). Pain was assessed by visual analog scale (VAS). Radiographs and magnetic resonance imaging (MRI) were performed to evaluate the recurrence of calcifications and the indemnity of the supraspinatus tendon repair. Significant improvement was obtained for pain (mean VAS, 8.7 before surgery to 0.8 after; P < .001). The mean Constant score increased from 23.9 preoperatively to 85.3 postoperatively (P < .001), the mean Quick DASH score decreased from 47.3 preoperatively to 8.97 postoperatively (P < .001), and the UCLA score increased from 15.8 preoperatively to 32.2 postoperatively (P < .001). MRI examination at last follow-up (70% of patients) showed no tendon tears, and 96.2% of patients were satisfied with their results. Arthroscopic removal and rotator cuff repair without acromioplasty can lead to good results in patients with symptomatic calcifying tendonitis of the supraspinatus tendon.

Continuous brachial plexus catheters are often used to decrease pain following elbow surgery. This investigation aimed to assess the rate of early failure of infraclavicular (IC) and axillary (AX) nerve catheters following elbow surgery. Retrospective study. Postoperative recovery unit and inpatient hospital floor. 328 patients who received IC or AX nerve catheters and underwent elbow surgery were identified by retrospective query of our institution's database. Data collected included unplanned catheter dislodgement, catheter replacement rate, postoperative pain scores, and opioid administration on postoperative day 1. Catheter failure was defined as unplanned dislodging within 24 h of placement or requirement for catheter replacement and evaluated using a covariate adjusted model. 119 IC catheters and 209 AX catheters were evaluated. There were 8 (6.7%) failed IC catheters versus 13 (6.2%) failed AX catheters. After adjusting for age, BMI, and gender there was no difference in catheter failure rate between IC and AX nerve catheters (p = 0.449). These results suggest that IC and AX nerve catheters do not differ in the rate of early catheter failure, despite differences in anatomic location and catheter placement techniques. Both techniques provided effective postoperative analgesia with median pain scores < 3/10 for patients following elbow surgery. Reasons other than rate of early catheter failure should dictate which approach is performed. Copyright © 2018. Published by Elsevier Inc.

Corticosteroid injections have been widely used for reducing shoulder pain. However, catastrophic complications induced by corticosteroid such as infections and tendon degeneration have made surgeons hesitant to use a corticosteroid injection as a pain control modality, especially during the postoperative recovery phase. To determine the effectiveness and safety of a subacromial corticosteroid injection for persistent pain control during the recovery period and to analyze the factors causing persistent pain after arthroscopic rotator cuff repair. Cohort study; Level of evidence, 3. A total of 458 patients who underwent arthroscopic rotator cuff repair were included in this study. Patient-specific parameters, tear size and pattern, and pain intensity were reviewed. Seventy-two patients were administered a postoperative subacromial corticosteroid injection under ultrasound guidance. The corticosteroid injection was administered to patients who awakened overnight because of constant severe shoulder pain or whose pain was exacerbated at the time of rehabilitation exercises within 8 weeks after surgery. Pain intensity, patient satisfaction, and functional outcomes using the American Shoulder and Elbow Surgeons (ASES) and Constant scores were compared between the patients with and without a subacromial corticosteroid injection. The retear rate was evaluated with magnetic resonance imaging at 6 months postoperatively. In patients with an injection, the mean (±SD) visual analog scale for pain (pVAS) score was 7.7 ± 1.2 at the time of the injection. This significantly decreased to 2.3 ± 1.4 at the end of the first month after the injection, demonstrating a 70.2% reduction in pain (P < .01). At 3 months after the injection, the mean pVAS score was 1.2 ± 1.8. Functional outcomes at final follow-up showed no significant differences between patients with and without an injection (ASES score: 90.1 ± 14.6 with injection, 91.9 ± 8.2 without injection [P = .91]; Constant score: 89.1 ± 12.9 with injection, 84.5 ± 13.0 without injection [P = .17]). Patients with an injection showed no significant increase in the retear rate (6.8% with injection, 18.4% without injection; P = .06). According to the tear pattern, L-shaped rotator cuff tears (41.8%) showed a higher occurrence of severe postoperative persistent pain. Preoperative shoulder stiffness was revealed as a predisposing factor for persistent pain (odds ratio, 0.2; P = .04). A subacromial corticosteroid injection can be considered as a useful and safe modality for the treatment of patients having severe persistent pain during the recovery phase after arthroscopic rotator cuff repair. © 2016 The Author(s).

We present a randomized clinical trial to compare postoperative pain, complications, feeling of a foreign body, and recurrence between heavyweight and lightweight meshes in patients with bilateral groin hernia. Sixty-seven patients with bilateral hernia were included in our study. In each patient, the side of the lightweight mesh was decided by random numbers table. Pain score was measured by visual analogue scale, on 1st, 3rd, 5th, and 7th postoperative day, and one year after the surgery. There were no statistically significative differences between both meshes in postoperative complications. About differences of pain average, there were statistically significant differences only on the 1st postoperative day (P <0.01) and the 7th postoperative day (P <0.05). In the review after a year, there were no statistically significative differences in any parameter. In our study, we did not find statistically significative differences between lightweight and heavyweight meshes in postoperative pain, complications, feeling of a foreign body, and recurrence, except pain on 1st and 7th postoperative day.

To compare postoperative pain control in patients treated surgically for ankle fractures who receive popliteal blocks with those who received general anesthesia alone. Institutional Review Board approved prospective randomized study. Metropolitan tertiary-care referral center. All patients being treated with open reduction internal fixation for ankle fractures who met inclusion criteria and consented to participate were enrolled. Patients were randomized to receive either general anesthesia (GETA) or intravenous sedation and popliteal block. Patients were assessed for duration of procedure, total time in the operating room, and postoperative pain at 2, 4, 8, 12, 24, and 48 hours after surgery using a visual analog scale. Fifty-one patients agreed to participate in the study. Twenty-five patients received popliteal block, while 26 patients received GETA. There were no anesthesia-related complications. At 2, 4, and 8 hours postoperatively, patients who underwent GETA demonstrated significantly higher pain. At 12 hours, there was no significant difference between the 2 groups with regard to pain control. However, by 24 hours, those who had received popliteal blocks had significantly higher pain with no difference by 48 hours. Popliteal block provides equivalent postoperative pain control to general anesthesia alone in patients undergoing operative fixation of ankle fractures. However, patients who receive popliteal blocks do experience a significant increase in pain between 12 and 24 hours. Recognition of this "rebound pain" with early narcotic administration may allow patients to have more effective postoperative pain control.

Children with attention-deficit hyperactivity disorder (ADHD) may experience pain differently compared to other children, yet the evidence is equivocal regarding whether pain is heightened or dampened. This prospective observational study, therefore, was designed to compare the postoperative pain experiences in children with and without ADHD. Children aged 7-17 years with a diagnosis of ADHD (n = 119) who were scheduled for a surgical procedure requiring postoperative pain management and a matched cohort of children without ADHD were recruited (n = 122). Postoperative pain scores and analgesic use were recorded for 1 week, as was parents' estimate of their child's return to normal activity. There were no differences in highest pain scores between children with ADHD (3.3 ± 2.5, 0-10 numerical rating scale) and those without (2.8 ± 1.9). Postoperative opioid use was also similar on day 1 following surgery (0.12 ± 0.3 mg·kg(-1) vs 0.08 mg·kg(-1 ) ± 0.1 morphine equivalents, respectively). Children with ADHD, however, had a significantly longer return to normal activity (4.9 ± 3.8 vs 3.8 ± 3.0 days; P < 0.05). Results suggest that there were no differences in the postoperative pain experiences of children with and without ADHD. However, the observation that children with ADHD took longer to return to baseline activity will be important in educating parents regarding their child's postoperative experience. © 2015 John Wiley & Sons Ltd.

Using Pictures to Assess Pain Location in Children.

2018-06-01

This study uses the Pain Area Locator (PAL) tool, a picture communication aid with body and medical equipment icons, to identify pain location in postoperative pediatric patients and assesses discrepancies between nurses' pain location assessment and pain location identified using the PAL tool. This descriptive study used a quantitative, comparative design, with a convenience sample of pediatric postoperative patients undergoing same-day surgeries at a free-standing, acute care, Magnet designated pediatric hospital. The child's pain location was assessed by asking the child to point to one of the 12 pictures on the PAL tool of where they hurt. All 41 (100%) of the postoperative children in the study demonstrated ability to use the PAL tool. The child identified a pain location in 34 assessments (83%) when the nurse documented no pain location. This investigation expands on previous evidence supporting that children can use the PAL tool to identify the pain location postoperatively.

Undertreatment of postoperative pain can aggravate patient outcomes and is associated with attending nurses' knowledge deficits or negative attitudes toward pain. The aim of this study was to investigate knowledge and attitudes toward postoperative pain of surgical department nurses and to identify predictors of their knowledge and attitudes. This was a descriptive, cross-sectional survey that took place in the departments of general surgery, orthopedics, neurosurgery, ear-nose-throat surgery, and obstetrics/gynecology at five Greek hospitals. Participants were a convenience sample of registered and assistant nurses. Nurses were asked to complete a three-section questionnaire, which included demographics, a Knowledge and Attitudes Survey Regarding Pain (KASRP) tool modified for postoperative pain, and seven questions capturing personal characteristics, working conditions, and feelings about work. One hundred eighty-two questionnaires were completed. Average scores were 45.35% for modified KASRP tool; 28.57% for pain assessment; 55.44% for general pain management; and 47.13% for use of analgesics. Four of the five most commonly missed items referred to use of analgesics. More previous personal experience of postoperative pain (p = .002) and being a registered nurse (p = .015) predicted higher modified KASRP tool score. Participation in continuing education programs and department of employment were also associated with differences in the modified tool score. The knowledge deficits and negative attitudes of the nurses toward postoperative pain highlight the role of pregraduate and continuing education, appropriately specialized for each surgical department, in the development of empathy toward patients in pain and of clinical competency regarding pain assessment and administration of analgesics.

Herrmann, Anja; De Wilde, Rudy Leon

2015-01-01

Background. We tested the hypothesis that warm-humidified carbon dioxide (CO2) insufflation would reduce postoperative pain and morphine requirement compared to cold-dry CO2 insufflation. Methods. A double-blinded, randomized, controlled trial was conducted to compare warm, humidified CO2 and cold-dry CO2. Patients with benign uterine diseases were randomized to either treatment (n = 48) or control (n = 49) group during laparoscopically assisted vaginal hysterectomy. Primary endpoints of the study were rest pain, movement pain, shoulder-tip pain, and cough pain at 2, 4, 6, 24, and 48 hours postoperatively, measured by visual analogue scale. Secondary outcomes were morphine consumption, rejected boli, temperature change, recovery room stay, and length of hospital stay. Results. There were no significant differences in all baseline characteristics. Shoulder-tip pain at 6 h postoperatively was significantly reduced in the intervention group. Pain at rest, movement pain, and cough pain did not differ. Total morphine consumption and rejected boli at 24 h postoperatively were significantly higher in the control group. Temperature change, recovery room stay, and length of hospital were similar. Conclusions. Warm, humidified insufflation gas significantly reduces postoperative shoulder-tip pain as well as morphine demand. This trial is registered with Clinical Trial Registration Number   DRKS00003853 (German Clinical Trials Register (DRKS)). PMID:25722977

Minimally invasive surgical techniques have many benefits, including reduced postoperative pain. Despite this, most patients require opioid analgesia, which can have significant side effects and toxicity. We report the first urologic study using multimodal analgesia with pregabalin, a gabapentinoid. The present retrospective study included 60 patients who underwent robotic-assisted laparoscopic radical prostatectomy. Of the 60 patients, 30 received multimodal treatment with pregabalin 150 mg, acetaminophen 975 mg, and celecoxib 400 mg orally 2 hours before the start of the procedure and continued postoperatively. These patients were compared with 30 consecutive previous patients, who had received a standard postoperative analgesic regimen with intravenous ketorolac 15 mg every 6 hours with oxycodone 5 mg and acetaminophen 325 mg, 1 to 2 tablets, every 4 hours as needed for pain. The patients in the multimodal treatment group had a significantly reduced intraoperative opioid requirement, as measured by the mean morphine equivalent dose administered (38.4 ± 2.73 mg vs 49.1 ± 2.65 mg; P < .01). The mean postoperative opioid use was also significantly reduced (10.7 ± 2.82 mg vs 26.2 ± 6.56 mg; P = .034), as was the mean total morphine equivalent dose administered (49.1 ± 2.7 mg vs 75.3 ± 4.6 mg; P < .001). The operative time, estimated operative blood loss, antiemetic use, postoperative creatinine and hemoglobin levels, and length of stay were similar in the 2 groups. No operative or treatment complications occurred in either group. The present retrospective review has indicated that a multimodal analgesic approach with pregabalin and celecoxib administered preoperatively decreases intraoperative and postoperative opioid use in patients undergoing robotic-assisted laparoscopic radical prostatectomy.

A growing interest in the possible influences of pre- and postoperative anxiety and pain scores as outcomes of surgical treatment and benefits of anxiety or pain-reducing interventions has emerged. The aim of this study was to evaluate the influence of three different premedication regimens on postoperative pain and anxiety in children. A prospective, randomized, open-label clinical trial enrolled 60 schoolchildren. They were randomized for premedication with oral midazolam 0.5 mgxkg(-1), oral clonidine 4 microgxkg(-1), or transmucosal dexmedetomidine (DEX) 1 mug.kg(-1), submitted to a pre- and postoperative evaluation of anxiety with the State-Trait Anxiety Inventory for Children and asked to report any pain in verbal and visual analog scales. We also evaluated secondary outcomes such as parents' anxiety, sedation, separation from parents, adverse effects and hemodynamic status. Dexmedetomidine and clonidine were related to lower scores of pain than midazolam. alpha(2)-agonists produced lower scores of peroperative mean arterial pressure and heart rate than midazolam. Both groups had similar levels of postoperative state-anxiety in children. There was no difference in preanesthesia levels of sedation and response to separation from parents between groups. These findings indicate that children receiving clonidine or DEX preoperatively have similar levels of anxiety and sedation postoperatively as those receiving midazolam. However, children given alpha(2)-agonists had less perioperative sympathetic stimulation and less postoperative pain than those given midazolam.

Previous studies have addressed post-operative pain management after ACL reconstruction by examining the use of intra-articular analgesia and/or modification of anesthesia techniques. To our knowledge, however, no previous studies have evaluated the effect of zolpidem on post-operative narcotic requirements, pain, and fatigue in patients undergoing outpatient arthroscopic ACL reconstruction. The purpose of this prospective, blinded, randomized, controlled clinical study was to evaluate the effect of zolpidem on post-operative narcotic requirements, pain, and fatigue in patients undergoing outpatient arthroscopic ACL reconstruction. Twenty-nine patients undergoing arthroscopic ACL reconstruction were randomized to a treatment group or placebo group. Both groups received post-operative hydrocodone/acetaminophen bitartrate (Vicodin ES). Patients in the treatment group received a single dose of zolpidem for the first seven post-operative nights. Patients in the placebo group received a gelatin capsule similar in appearance to zolpidem. The amount of Vicodin used in each group, the amount of post-operative pain, and the amount of post-operative fatigue were analyzed. Following ACL reconstruction, a 28% reduction was seen in the total amount of narcotic consumed with zolpidem (P = 0.047) when compared to placebo. There were no significant differences in post-operative pain or fatigue levels between zolpidem and placebo. Adding zolpidem to the post-operative medication regimen after arthroscopic ACL reconstruction helps to lower the amount of narcotic pain medication required for adequate analgesia. Randomized controlled clinical trial, Level I.

Pain management is critical for patients after surgery, but current pain management methods are not always adequate. Massage therapy may be a therapeutic complementary therapy for pain. Many researchers have investigated the effects of massage therapy on post-operative pain, but there have been no systematic reviews and meta-analysis of its efficacy for post-operative patients. Our objective was to assess the effects of massage therapy on pain management among post-operative patients by conducting a systematic review and meta-analysis. The databases searched included MEDLINE, CINAHL, and the Cochrane Library's CENTRAL. To assess the effects of massage therapy on post-operative pain and anxiety, we performed a meta-analysis and calculated standardized mean difference with 95% CIs (Confidential Intervals) as a summary effect. Ten randomized controlled trials were selected (total sample size = 1,157). Meta-analysis was conducted using subgroup analysis. The effect of single dosage massage therapy on post-operative pain showed significant improvement (-0.49; 95% confidence intervals -0.64, -0.34; p < .00001) and low heterogeneity (p = .39, I 2 = 4%), sternal incisions showed significant improvement in pain (-0.68; -0.91, -0.46; p< .00001) and low heterogeneity (p = .76, I 2 = 0%). The anxiety subgroups showed substantial heterogeneity. The findings of this study revealed that massage therapy may alleviate post-operative pain, although there are limits on generalization of these findings due to low methodological quality in the reviewed studies.

Despite multimodal pain management and advances in anesthetic techniques, total knee arthroplasty (TKA) remains painful during the early postoperative phase. This trial investigated whether computer-assisted cryotherapy (CAC) is effective in reduction of pain and consumption of opioids in patients operated for TKA following an outpatient surgery pathway. Sixty patients scheduled for primary TKA were included in this prospective, double-blind, randomized controlled trial receiving CAC at 10-12 °C (Cold-group, n = 30) or at 21 °C (Warm-group, n = 30) during the first 7 days after TKA according to a fixed schedule. All patients received the same pre-, peri- and postoperative care with a multimodal pain protocol. Pain was assessed before and after every session of cryotherapy using the numerical rating scale for pain (NRS-pain). The consumption of opioids was strictly noted during the first 4 postoperative days. Secondary outcomes were knee swelling, visual hematoma and patient reported outcome measures (PROMs). These parameters were measured pre-, 1, 2 and 6 weeks postoperatively. In both study groups, a reduction in NRS-pain after every CAC session were seen during the postoperative period of 7 days. A mean reduction of 0.9 and 0.7 on the NRS-pain was seen for respectively the Cold- (P = 0.008) and Warm-group (n.s.). A significant (P = 0.001) lower number of opioids were used by the Cold-group during the acute postoperative phase of 4 days, 47 and 83 tablets for respectively the Cold and Warm-group. No difference could be observed for secondary outcomes and adverse effects between both study groups. Postoperative CAC can be in added value in patients following an outpatient surgery pathway for TKA, resulting in reduced experienced pain and consumption of opioids during the first postoperative days.

The relief of post-cesarean delivery pain is important. Good pain relief improves mobility and reduces the risk of thromboembolic disease, which may have been increased during pregnancy. Pain may impair the mother's ability to optimally care for her infant in the immediate postpartum period and may adversely affect early interactions between mother and infant. It is necessary, therefore that pain relief be safe and effective and results in no adverse neonatal effects during breast-feeding. Music may be considered as a potential method of post cesarean pain therapy due to its noninvasiveness and lack of side effects. In this study we evaluated the effect of intraoperative music under general anesthesia for reducing the postoperative morphine requirements after cesarean section. In a double blind placebo-controlled trial, 100 women (ASA I) scheduled for elective cesarean section under general anesthesia, were randomly allocated into two groups of fifty. After standardization of anesthesia, patients in the music group were exposed to a compact disk of Spanish guitar after induction of anesthesia up to the time of wound dressing. In the control group patients were exposed to white music. Post operative pain and anxiety were evaluated by visual analog scale (VAS) up to six hours after discharge from PACU. Morphine was given intravenously for reducing pain to VAS < or = 3 postoperatively. There was not statistically significant difference in VAS for pain between two groups up to six hours postoperatively (P>0.05). In addition, morphine requirements were not different between two groups at different time intervals up to six hours postoperatively (P>0.05). There were not statistically significant difference between two groups regarding postoperative anxiety score and vomiting frequency (P>0.05). As per conditions of this study, intraoperative Spanish music was not effective in reducing postoperative pain after cesarean section. In addition postoperative morphine requirement, anxiety, and vomiting were not affected by the music during general anesthesia.

Cut-off points (CPs) of the numeric rating scale (NRS 0-10) are regularly used in postoperative pain treatment. However, there is insufficient evidence to identify the optimal CP between mild and moderate pain. A total of 435 patients undergoing general, trauma, or oral and maxillofacial surgery were studied. To determine the optimal CP for pain treatment, four approaches were used: first, patients estimated their tolerable postoperative pain intensity before operation; secondly, 24 h after surgery, they indicated if they would have preferred to receive more analgesics; thirdly, satisfaction with pain treatment was analysed, and fourthly, multivariate analysis was used to calculate the optimal CP for pain intensities in relation to pain-related interference with movement, breathing, sleep, and mood. The estimated tolerable postoperative pain before operation was median (range) NRS 4.0 (0-10). Patients who would have liked more analgesics reported significantly higher average pain since surgery [median NRS 5.0 (0-9)] compared with those without this request [NRS 3.0 (0-8)]. Patients satisfied with pain treatment reported an average pain intensity of median NRS 3.0 (0-8) compared with less satisfied patients with NRS 5.0 (2-9). Analysis of average postoperative pain in relation to pain-related interference with mood and activity indicated pain categories of NRS 0-2, mild; 3-4, moderate; and 5-10, severe pain. Three of the four methods identified a treatment threshold of average pain of NRS≥4. This was considered to identify patients with pain of moderate-to-severe intensity. This cut-off was indentified as the tolerable pain threshold.

OBJECTIVES Patients undergoing thoracotomy were studied to compare the effects of cryoanalgesia, combined with intravenous patient-controlled analgesia (IVPCA), against IVPCA alone during the four days following surgery. METHODS Fifty patients were randomized into two groups: an IVPCA group (n = 25) and an IVPCA-cryo group (n = 25). Subjective pain intensity was assessed on a verbal analogue scale at rest and during coughing. The intensity and the incidence of post-thoracotomy pain, numbness, epigastric distension and/or back pain, the analgesic requirements, as well as the blood gas values and respiratory function tests were evaluated up to the second postoperative (postop) month. Haemodynamic data and episodes of nausea and/or vomiting were recorded over the four postop days. RESULTS In the cryo group there was a statistically significant improvement in postop pain scores (P = 10–4), reduction in consumption of morphine (P = 10–4) and other analgesics (P = 10–4), optimization (less acidosis) of the pH values of blood gases (P < 0.015 over 72 hours postop and P < 0.03 on the first and second postop months), increase in systolic blood pressure (P < 0.05 over 96 hours postop), reduction in heart rate (P < 0.05 over 96 hours postop), increase in values of FEV1 (P < 0.02) and FVC (P < 0.05) at the first and second postop months, reduction in the incidence of nausea (0.05 < P < 0.1 over 18 hours postop), numbness, epigastric distension and back pain (P < 0.05 at days 5, 6, 7, 14, 30 and 60 following surgery). CONCLUSIONS We suggest that cryoanalgesia be considered as a simple, safe, inexpensive, long-term form of post-thoracotomy pain relief. Cryoanalgesia effectively restores FEV1 values at the second postop month. PMID:23424242

Cross-sectional evaluation of post-operative pain and flare-ups in endodontic treatments using a type of rotary instruments.

The purpose of this clinical study was to evaluate the general incidence of post-operative pain and flare-ups in patients who were endodontically treated by two endodontics specialists using rotary instruments (Hero 642, Micro Mega, France) with the same treatment protocol. Records of 382 teeth belonging to 268 patients treated by two endodontics specialists during a 6-month period were kept and evaluated. Post-operative pain between treatment visits was categorized using a pre-established scoring system. Ninety-five patients were males, whereas 173 were females. Pulpal necrosis without periapical pathosis was determined as the most common indication for endodontic treatment (21.7%) followed by irreversible pulpitis and re-treatment without periapical lesions (18.3%, 18.3%, respectively). The general prevalence of post-operative pain and flare-ups was determined as 8.1%, whereas cases that could be classified as real flare-ups which were severe and required an unscheduled visit (scores 2 and 3) comprised 3.4% of the cases. No statistically significant correlation was determined between gender and post-operative pain and flare-up (p = 0.05). There was a significant correlation between number of appointments and the presence of pain and flare-ups. Teeth undergoing multiple visits had a higher risk of developing post-operative pain and flare-ups compared to those with single appointments with a statistical significance (p = 0.03). Teeth with pre-operative pain were more prone to developing post-operative pain and discomfort with a statistically significant difference (p = 0.02). While no significant correlation was determined between tooth vitality and pain and flare-ups (p = 0.5), a statistically significant relationship existed between the presence of a periapical pathosis and post-operative pain and flare-ups. Cases with a periapical lesion had a higher risk of developing pain and flare-ups compared to those with no periapical involvement (p = 0.0001). Future studies may focus on the influence of rotary instrumentation systems in more specific groups of cases. Meanwhile; microbiological as well as psychological aspects of flare-ups are topics that warrant further investigation.

This study aimed to observe the postoperative pain rate and degree of pain in preschool children with cleft lip and palate, and investigate the effect of nursing intervention on pain relief. A total of 120 hospitalized cases of three- to seven-year-old preschool children with cleft lip and palate were selected from May to October 2011. The subjects were randomly divided into the control group and experimental groups 1, 2, and 3. The control group used conventional nursing methods, experimental group 1 used analgesic drug treatment, experimental group 2 used psychological nursing interventions, and experimental group 3 used both psychological nursing intervention and analgesic drug treatment. After 6, 12, 24, and 48 h, pain self-assessment, pain parent-assessment, and pain nurse-assessment were calculated for the four groups using the pain assessment forms, and their ratings were compared. The postoperative pain rates of the four groups ranged from 50.0% to 73.3%. The difference among the four groups was statistically significant (P < 0.001). The differences among the control group and experimental groups 1 and 2 were not statistically significant (P = 0.871), whereas the differences among experimental group 3 and the other groups were statistically significant (P < 0.001). Postoperative pain in preschool children with cleft lip and palate is common. Psychological nursing intervention with analgesic treatment is effective in relieving postoperative pain.

To examine whether acetaminophen with codeine administered per rectum is an effective alternative for pain control compared with oral administration after an adenotonsillectomy. A prospective, randomized control study. Seventy-five children aged 1 to 5 were recruited for this study. Each child was assigned randomly to receive either rectal or oral postoperative pain medication. A journal with eight questions was kept for 10 days after the operation, and an overall survey of five questions was filled out at the first postoperative visit. Postoperative pain was adequately controlled in those patients receiving suppositories when compared with those patients receiving oral pain medication. Adverse effects and total number of doses given per day were similar. Parents found the suppositories easy to administer, and more parents would switch or consider switching from oral pain medication to suppositories if given the choice. The suppositories achieved equivalent pain control as oral medication with few side effects and good tolerance. Furthermore, many parents preferred the suppositories to oral medication in maintaining postoperative pain control because of ease of administration. If given the choice for future surgeries, many parents would switch or consider switching from oral pain medication to suppositories.

Pain is common in patients after orthopedic surgery. The 11-face Faces Pain Scale has not been validated for use in adult patients with postoperative pain. To assess the validity of the 11-face Faces Pain Scale and its ability to detect responses to pain medications, and to determine whether the sensitivity of the 11-face Faces Pain Scale for detecting changes in pain intensity over time is associated with gender differences in adult postorthopedic surgery patients. The 11-face Faces Pain Scale was translated into Vietnamese using forward and back translation. Postoperative pain was assessed using an 11-point numerical rating scale and the 11-face Faces Pain Scale on the day of surgery, and before (Time 1) and every 30 minutes after (Times 2-5) the patients had taken pain medications on the first postoperative day. The 11-face Faces Pain Scale highly correlated with the numerical rating scale (r = 0.78, p < .001). When the scores from each follow-up test (Times 2-5) were compared with those from the baseline test (Time 1), the effect sizes were -0.70, -1.05, -1.20, and -1.31, and the standardized response means were -1.17, -1.59, -1.66, and -1.82, respectively. The mean change in pain intensity, but not gender-time interaction effect, over the five time points was significant (F = 182.03, p < .001). Our results support that the 11-face Faces Pain Scale is appropriate for measuring acute postoperative pain in adults. Copyright © 2015 American Society for Pain Management Nursing.

To evaluate the quality of postoperative pain relief during the first 3 days after surgery and to evaluate with the incidence of persistent pain at 6 months after surgery. Retrospective single-center audit. University hospital. Five hundred four patients who underwent thoracotomy. Review of patient records, questionnaire, and telephone review. Of the 364 survivors, 306 were contacted. Five or more episodes of severe pain (numerical rating scale >6/10 at rest or movement) during the first 72 hours after surgery occurred in 133 patients. Persistent postsurgical pain at 6 months was present in 82% (109/133) of these patients. Patient satisfaction with acute postoperative pain management was excellent (36%), good (43%), and fair or poor (21%).The incidence of postthoracotomy pain was 56% (mild 32%, moderate 18%, and severe 6%). Poorly controlled acute postoperative pain correlated with persistent postsurgical pain at 6 months. In view of such a high incidence in thoracotomy patients, preventative strategies assume great significance. Copyright © 2016 Elsevier Inc. All rights reserved.

Perioperative parecoxib administration reduces postoperative pain, opioid consumption, and adverse events in adult patients. However, the efficacy and safety of parecoxib in children remain unclear. This metaanalysis included related published studies to address this concern. Eight databases in the literature until February 2015 were systematically explored to identify randomized controlled trials (RCTs) comparing perioperative parecoxib administration and placebo/standard treatments for acute postoperative pain in children. Primary outcomes were postoperative pain scores and adverse events. The Face, Legs, Activity, Crying, Consolability scale was used to score pain in children younger than 6 years, whereas the Visual Analog Scale was used in children older than 6 years. Secondary outcomes were sedation scores (measured using the Ramsay scale), agitation scores (measured using the Sedation-Agitation Scale), and opioid consumption. The methodological quality of RCTs was independently assessed in accordance with the "Risk of bias" of Cochrane Collaboration. Data were analyzed using Review Manager 5.2. Twelve RCTs involving 994 patients met the inclusion criteria. Compared with children who received placebo treatment, those who received parecoxib demonstrated lower early (2 h) and later (12 h) postoperative pain scores; lower incidence rates of postoperative nausea, vomiting, and agitation; higher early (1 h) postoperative sedation scores; and lower agitation scores. Similarly, children who received parecoxib had lower early (2 h) and later (12 h) postoperative pain scores, lower incidence rates of postoperative nausea and vomiting, and lower early (1 h) postoperative sedation scores compared with those who received standard treatments; however, these children showed no significant difference in agitation scores. Unfortunately, data on the effect of parecoxib on opioid consumption were insufficient. Overall, these results suggested that perioperative parecoxib administration was associated with less acute postoperative pain and fewer adverse events compared with placebo or standard treatments. Parecoxib administration also resulted in less emergence agitation compared with placebo treatment and less excessive sedation concern compared with standard treatments. However, the long-term effects, effects on opioid consumption, and patient satisfaction of parecoxib administration warrant further investigation.

To assess postoperative pain in endodontic therapy and its association with clinical factors such as gender, age, tooth type, pulpal diagnosis, and preoperative pain, length of obturation and sealer extrusion. Cross-Sectional study. Dental section of the Aga khan university hospital, Karachi, Pakistan from January to December 2009. One hundred and forty patients (140) requiring endodontic therapy for molar and premolar teeth were included in this study. Local Anesthesia (2% Lidocain with 1:80,000 Epinephrine) was administered. The tooth was isolated with rubber dam. Access cavity was prepared with the help of round carbide No. 2 bur. Canal preparation was completed using crown-down technique. Access was sealed with sterile dry cotton pallet and restored temporarily with double layer of Glass ionomer cement and Cavit. After one week patients were recalled and access was re-opened, obturation was done using cold lateral condensation technique. Ca(OH)(2) based sealer was used. Postoperative radiographs were taken. Patients were recalled after 24 hours and postobturation pain was recorded using Visual analogue scale (VAS).Data was obtained on a structured Performa. χ(2) test was used for statistical analysis. Pain was present in 42.9% of patients. Females more frequently experienced pain (65%) than males (35%). Preoperative pain was found to be significantly associated with postoperative pain (p value < 0.001). Obturation length was not found to be significantly associated with postoperative pain (p value 1.0). Sealer extrusion was not found to be significantly associated with postoperative (P value 0.547).

Management of postoperative pain often requires multimodal approaches. Suboptimal dosages of current therapies can leave patients experiencing periods of insufficient analgesia, often requiring rescue therapy. With absence of a validated and standardized approach to pain management, further refinement of treatment protocols and targeted therapeutics is needed. Liposomal bupivacaine (Exparel) is a longer acting form of traditional bupivacaine that delivers the drug by means of a multivesicular liposomal system. The effectiveness of liposomal bupivacaine has not been systematically analyzed relative to conventional treatments in plastic surgery. A comprehensive literature search of the MEDLINE, PubMed, and Google Scholar databases was conducted for studies published through October of 2015 with search terms related to liposomal bupivacaine and filtered for relevance to postoperative pain control in plastic surgery. Data on techniques, outcomes, complications, and patient satisfaction were collected. A total of eight articles were selected and reviewed from 160 identified. Articles covered a variety of techniques using liposomal bupivacaine for postoperative pain management. Four hundred five patients underwent procedures (including breast reconstruction, augmentation mammaplasty, abdominal wall reconstruction, mastectomy, and abdominoplasty) where pain was managed with liposomal bupivacaine and compared with those receiving traditional pain management. Liposomal bupivacaine use showed adequate safety and tolerability and, compared to traditional protocols, was equivalent or more effective in postoperative pain management. Liposomal bupivacaine is a safe method for postoperative pain control in the setting of plastic surgery and may represent an alternative to more invasive pain management systems such as patient-controlled analgesia, epidurals, peripheral nerve catheters, or intravenous narcotics.

The purpose of this study was to compare the effect of compressive cryotherapy (CC) vs. ice on postoperative pain in patients undergoing shoulder arthroscopy for rotator cuff repair or subacromial decompression. A commercial device was used for postoperative CC. A standard ice wrap (IW) was used for postoperative cryotherapy alone. Patients scheduled for rotator cuff repair or subacromial decompression were consented and randomized to 1 of 2 groups; patients were randomized to use either CC or a standard IW for the first postoperative week. All patients were asked to complete a "diary" each day, which included visual analog scale scores based on average daily pain and worst daily pain as well as total pain medication usage. Pain medications were then converted to a morphine equivalent dosage. Forty-six patients completed the study and were available for analysis; 25 patients were randomized to CC and 21 patients were randomized to standard IW. No significant differences were found in average pain, worst pain, or morphine equivalent dosage on any day. There does not appear to be a significant benefit to use of CC over standard IW in patients undergoing shoulder arthroscopy for rotator cuff repair or subacromial decompression. Further study is needed to determine if CC devices are a cost-effective option for postoperative pain management in this population of patients.

Effective management of postoperative pain is a part of well-organized perioperative care, which helps in reduced morbidity and improved patient satisfaction. Preventive analgesia can reduce acute and chronic pain by blocking the noxious inputs to pain pathways, preventing sensitization. Studies have reported efficacy of gabapentin as a preventive analgesic in perioperative pain. In this study, we aimed to determine whether preoperative gabapentin reduced postoperative pain and tramadol consumption after thyroidectomy under general anesthesia. Sixty patients scheduled for thyroidectomy were allocated to two groups of thirty each for this prospective, observational study. Patients in Group A and Group B received oral gabapentin 600 mg (6 × 10 -4 kg) and diazepam 10 mg (1 × 10 -5 kg), respectively, 2 h prior to surgery. Tramadol was given as rescue analgesic for postoperative pain with a verbal rating score of two. The analgesic efficacy of preoperative gabapentin was assessed in terms of postoperative pain scores at rest or swallowing, time to first rescue analgesic, and total tramadol consumption for 24 h. Ramsay sedation score and side effects of drug were also looked into. Postoperative pain scores and total tramadol consumption were significantly lower in Group A during 24 h ( P = 0.00). Time to first rescue analgesic was significantly prolonged in Group A ( P = 0.001). Side effects were comparable. Oral gabapentin is effective as a preventive analgesic in reducing postoperative pain and tramadol consumption after thyroidectomy under general anesthesia.

We compared perioperative results and complications of reconstructive surgery of the urinary tract performed using a multichannel platform through the umbilicus and one additional 3.5-mm with a cohort of patients simultaneously treated with conventional 4-port laparoscopy. Matched-pair study comparing perioperative outcomes, postoperative visual analogue pain scale (VAPS) and morbidity of 2-port (n = 20) and 4-port (n = 10) laparoscopic reconstructive urological surgery. Preoperative and perioperative data compared included demographics, type of surgery, operative time, blood loss, decrease in serum hemoglobin, operative complications, length of stay and postoperative complications according to Clavien-Dindo classification. There was no significant difference between groups regarding age, gender, body mass index, American Society of Anesthesiologists score, type of surgery, operative time, operative complications and intraoperative or postoperative transfusion. Estimated blood loss was lower using reduced-port approach. VAPS at postoperative day one was significantly lower for 2-port approach and so was the length of stay. Patient satisfaction with the wound was higher for 2-port surgery. Differences were not observed in number and severity of postoperative complications. Urological reconstructive operations can be safely performed using the hybrid laparoendoscopic single-site umbilical approach, resulting in lower blood loss, higher patient satisfaction and lower postoperative pain, which also facilitate earlier hospital discharge, than the same reconstructive procedures performed through multiport conventional laparoscopy. © 2016 S.

(i) To determine whether a central tendency, median, based on patients' self-rated pain is a clinically applicable daily measure to show patients' postoperative pain on the first day after major surgery (ii) and to determine the number of self-ratings required for the calculation of this measure. Perioperative pain traits in medical records are difficult to overview. The clinical applicability of a daily documented summarising measure of patients' self-rated pain scores is little explored. A repeated measure design was carried out at three Swedish country hospitals. Associations between the measures were analysed with nonparametric statistical methods; systematic and individual group changes were analysed separately. Measure I: pain scores at rest and activity postoperative day 1; measure II: retrospective average pain from postoperative day 1. The sample consisted of 190 general surgery patients and 289 orthopaedic surgery patients with a mean age of 65; 56% were men. Forty-four percent had a pre-operative daily intake of analgesia, and 77% used postoperative opioids. A range of 4-9 pain scores seem to be eligible for the calculation of the daily measures of pain. Rank correlations for individual median scores, based on four ratings, vs. retrospective self-rated average pain, were moderate and strengthened with increased numbers of ratings. A systematic group change towards a higher level of reported retrospective pain was significant. The median values were clinically applicable daily measures. The risk of obtaining a higher value than was recalled by patients seemed to be low. Applicability increased with increased frequency of self-rated pain scores and with high-quality pain assessments. The documenting of daily median pain scores at rest and during activity could constitute the basis for obtaining patients' experiences by showing their pain severity trajectories. The measures could also be an important key to predicting postoperative health-related consequences. © 2017 John Wiley & Sons Ltd.

To evaluate the pain-related behavioral changes in rats with bilateral chronic constriction injury(bCCI)and identify the expressions of neuropathic pain-related proteins. The bCCI models were established by ligating the sciatic nerves in female Sprague Dawley rats. Both mechanical hyperalgesia and cold hyperalgesia were evaluated through electronic von Frey and acetone method. Liquid chromatography-mass spectrometry/mass spectrometry was applied to characterize the differentially expressed proteins. Both mechanical withdrawal threshold and cold hyperalgesia threshold decreased significantly on the postoperative day 7 and 14, when compared with na ve or sham rats(P <0.05). Twenty five differentially expressed proteins associated with bilateral CCI were discovered, with eighteen of them were upregulated and seven of them downregulated. The bCCT rats have remarkably decreased mechanical and cold hyperalgesia thresholds. Twenty five neuropathic pain-related proteins are found in the spinal cord dorsal horn.

Abstract Background: Robotic or endoscopic thyroidectomy using bilateral axillo-breast approach (BABA) is frequently performed for excellent cosmesis. However, postoperative pain is remained as concerns due to the extent tissue dissection and tension during the operation. Ketamine is a noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist that reduces acute postoperative pain. We evaluated the effects of intraoperative ketamine infusion on postoperative pain control and recovery profiles following BABA robotic or endoscopic thyroidectomy. Methods: Fifty-eight adult patients scheduled for BABA robotic or endoscopic thyroidectomy were randomized into a control group (n = 29) and ketamine group (n = 29). Following induction of anesthesia, patients in each group were infused with the same volume of saline or ketamine solution (1 mg/kg bolus, 60 μg/kg/h continuous infusion). Total intravenous anesthesia with propofol and remifentanil was used to induce and maintain anesthesia. Pain scores (101-point numerical rating scale, 0 = no pain, 100 = the worst imaginable pain), the consumption of rescue analgesics, and other postoperative adverse effects were assessed at 1, 6, 24, and 48 hours postoperatively. Results: Patients in the ketamine group reported lower pain scores than those in the control group at 6 hours (30 [30] vs 50 [30]; P = 0.017), 24 hours (20 [10] vs 30 [20]; P < 0.001), and 48 hours (10 [10] vs 20 [15]; P < 0.001) in neck area. No statistically significant differences were found between the 2 groups in terms of the requirements for rescue analgesics or the occurrence of adverse events. Conclusion: Intravenous ketamine infusion during anesthesia resulted in lower postoperative pain scores following BABA robotic or endoscopic thyroidectomy, with no increase in adverse events.

To assess the influence of topical ozone administration on patient comfort after third molar surgery. A single-blinded randomized controlled clinical trial was designed involving patients who required removal of bilateral impacted mandibular third molars. The predictor variable was the postoperative medication used after third molar surgery. Using the split-mouth design, the study group received topical ozone without postoperative systemic antibiotics, whereas the control group did not receive ozone but only systemic antibiotics. The 2 groups were prescribed analgesics for 2 days. The assessing surgeon was blinded to treatment assignment. The primary outcome variables were postoperative mouth opening, pain, and swelling. The secondary outcome variable was the number of analgesic doses required by each group on postoperative days 3 to 5. Data analysis involved descriptive statistics, paired t tests, and 2-way analysis of variance with repeated measures (P < .05). SPSS 20.0 was used for data analysis. The study sample included 33 patients (n = 33 in each group). The study group showed statistically relevant decreases in postoperative pain, swelling, and trismus. Further, the number of analgesics required was smaller than in the control group. No adverse effects of ozone gel were observed in any patient. Ozone gel was found to be an effective topical agent that considerably improves patient comfort postoperatively and can be considered a substitute of postoperative systemic antibiotics.

Background: The optimal postoperative analgesia after primary total hip arthroplasty remains in question. This randomized, double-blind, placebo-controlled study compared the use of patient-controlled epidural analgesia (PCEA) with use of a multimodal pain regimen including periarticular injection (PAI). We hypothesized that PAI would lead to earlier readiness for discharge, decreased opioid consumption, and lower pain scores. Methods: Forty-one patients received PAI, and forty-three patients received PCEA. Preoperatively, both groups were administered dexamethasone (6 mg, orally). The PAI group received a clonidine patch and sustained-release oxycodone (10 mg), while the PCEA group had placebo. Both groups received combined spinal-epidural anesthesia and used an epidural pain pump postoperatively; the PAI group had normal saline solution, while the PCEA group had bupivacaine and hydromorphone. The primary outcome, readiness for discharge, required the discontinuation of the epidural, a pain score of <4 (numeric rating scale) without parenteral narcotics, normal eating, minimal nausea, urination without a catheter, a dry surgical wound, no acute medical problems, and the ability to independently transfer and walk 12.2 m (40 ft). Results: The mean time to readiness for discharge (and standard deviation) was 2.4 ± 0.7 days (PAI) compared with 2.3 ± 0.8 days (PCEA) (p = 0.86). The mean length of stay was 3.0 ± 0.8 days (PAI) compared with 3.1 ± 0.7 days (PCEA) (p = 0.46). A significant mean difference in pain score of 0.74 with ambulation (p = 0.01; 95% confidence interval [CI], 0.18 to 1.31) and 0.80 during physical therapy (p = 0.03; 95% CI, 0.09 to 1.51) favored the PCEA group. The mean opioid consumption (oral morphine equivalents in milligrams) was significantly higher in the PAI group on postoperative day 0 (43 ± 21 compared with 28 ± 23; p = 0.002) and postoperative days 0 through 2 (136 ± 59 compared with 90 ± 79; p = 0.004). Opioid-Related Symptom Distress Scale (ORSDS) composite scores for severity and bothersomeness as well as scores for nausea, vomiting, and itchiness were significantly higher in the PCEA group (p < 0.05). Quality of Recovery-40 scores and patient satisfaction were similar. Conclusions: PAI did not decrease the time to discharge and was associated with higher pain scores and greater opioid consumption but lower ORSDS scores compared with PCEA. The choice for analgesic regimen may depend on a particular patient’s threshold for pain and the potential side effects. Level of Evidence: Therapeutic Level I.

The aim of this study is to assess the long-term clinical and radiological outcomes between minimally invasive (MIS) and conventional transforaminal lumbar interbody fusion (TLIF) in treating one-segment lumbar disc herniation (LDH). One-hundred and six patients treated by MIS-TLIF (50 cases) or conventional TLIF (56 cases) were included. Perioperative results were evaluated. Clinical outcomes were compared preoperatively and postoperatively. Radiologic parameters were based on a comparison of preoperative and three-year postoperative lumbar lordosis, segmental lordosis, sacral slope, the cross-sectional area of the paraspinal muscle and fusion rates. MIS TILF had significantly less blood, shorter operation time, mean return to work time and lower intramuscular pressure compared with the conventional group during the operation. VAS scores for lower back pain and ODI in MIS-TLIF were significantly decreased. The mean cross-sectional area of the paraspinal muscle was significantly decreased after surgery in the conventional TLIF group and no significant intragroup differences were established in the MIS-TLIF group. No significant differences were found in fusion rate, lumbar lordosis, segmental lordosis and sacral slope. Both MIS and conventional TLIF were beneficial for patients with LDH. However, MIS-TLIF manifests a great improvement in perioperative outcomes, low back pain, disability and preventing paraspinal muscle atrophy during the follow-up period observation.

To evaluate the patient-reported pain perception after palatal graft harvesting during a 4 weeks healing period Ninety patients, scheduled for different periodontal and peri-implant plastic surgeries requiring palatal mucosal graft harvesting, were consecutively recruited. Mucosal thickness was measured at the donor sites with an ultrasonic device prior to the surgeries. Graft thickness, length, and width were assessed after harvesting, and the wound areas were calculated. Based on a Visual Analogue Scale (VAS), the patients were asked to report their perceived pain after the intervention and 1, 3, 7, 14, 21 and 28 days thereafter. Pain was most pronounced on the first postoperative day and decreased within the course of time. Graft thickness directly correlated with the amount of pain perceived while increased palatal mucosal thickness before and after graft harvesting decreased pain levels. The denuded wound surface area, however, did not influence the perceived pain level. The wound depth at the donor site (graft thickness) was positively correlated with the patient's perception for pain. The wound surface area, however, did not influence the perceived pain level. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Previous national survey research has shown significant deficits in routine postoperative pain management in the UK. This study used an organizational change perspective to explore in detail the organizational challenges faced by three acute pain services in improving postoperative pain management. Case studies were conducted comprising documentary review and semi-structured interviews (71) with anaesthetists, surgeons, nurses, other health professionals, and managers working in and around three broadly typical acute pain services. Although the precise details differed to some degree, the three acute pain services all faced the same broad range of inter-related challenges identified in the organizational change literature (i.e. structural, political, cultural, educational, emotional, and physical/technological challenges). The services were largely isolated from wider organizational objectives and activities and struggled to engage other health professionals in improving postoperative pain management against a background of limited resources, turbulent organizational change, and inter- and intra-professional politics. Despite considerable efforts they struggled to address these challenges effectively. The literature on organizational change and quality improvement in health care suggests that it is only by addressing the multiple challenges in a comprehensive way across all levels of the organization and health-care system that sustained improvements in patient care can be secured. This helps to explain why the hard work and commitment of acute pain services over the years have not always resulted in significant improvements in routine postoperative pain management for all surgical patients. Using this literature and adopting a whole-organization quality improvement approach tailored to local circumstances may produce a step-change in the quality of routine postoperative pain management.

Pain in the immediate post-operative period after anterior cruciate ligament (ACL) surgery, apart from an unpleasant experience for the patient, can act as a barrier for static quadriceps contractions and optimum execution of the initial rehabilitation protocol resulting in slow recovery and a later return to full function for a sportsperson. There is no report in the literature comparing pain in the immediate post-operative period after using the two most widely used autografts, bone patellar tendon bone (BPTB) graft and hamstring graft. The present study compared the visual analogue scale (VAS) pain score in the immediate post-operative period after arthroscopic ACL reconstruction with the BPTB and hamstring autografts. Both groups consisted of 50 patients each. The mean age of the BPTB and hamstring cohorts was 26.9 ± 7.3 years (age range 18-59 years) and 26.7 ± 9.0 years (age range 17-52 years), respectively. Unpaired t test was applied to compare pain scores between the BPTB and hamstring cohorts. In the present study, patients in the BPTB cohort showed higher mean pain scores across all the post-operative time intervals except at 6 h. However, the difference in the mean VAS pain score at post-operative 6, 12,18, 24, 36 and 48 h in the two groups was statistically not significant (p value of 1, 0.665, 0.798, 0.377, 0.651 and 0.215 at 6, 12, 18, 24, 36 and 48 h, respectively). Our study concludes that the arthroscopic ACL reconstruction with BPTB autograft and hamstring autograft is associated with similar pain in the immediate post-operative period. As a result, aggressive physiotherapy regime is not affected by the type of graft being used for ACL reconstruction, as the pain scores in the immediate post-operative period are similar for both techniques.

Exercise causes a variety of psychophysical effects (eg, alterations in pain sensation). Tissue injury induces mediator releases in the spinal cord resulting in pain hypersensitivity; however, the contribution of the dorsal root ganglion (DRG) is poorly understood. In this study, we tested if forced treadmill running can attenuate postoperative pain and alter substance P (SP) or proinflammatory cytokine level in the DRG by using a rat model of skin/muscle incision and retraction (SMIR). We evaluated mechanical sensitivity to von Frey stimuli (6 and 15 g) and expression of SP, interleukin-1β, and interleukin-6 in the DRG of sham-operated sedentary rats, SMIR sedentary rats, sham-operated rats with forced treadmill running, and SMIR rats with forced treadmill running. At postoperative day 8, trained rats ran for 5 days per week for 4 weeks on a treadmill 70 minutes/d with an intensity of 18 m/min. On postoperative day 6, SMIR sedentary rats displayed a significant mechanical hypersensitivity that persisted until postoperative day 35. By comparison, SMIR-operated rats, which received forced treadmill running, exhibited a quick recovery from mechanical hypersensitivity. SMIR sedentary rats showed an upregulation of SP, interleukin-1β, and interleukin-6 in the DRG at postoperative days 14 and 28, whereas SMIR-operated rats receiving forced treadmill running reversed this upregulation at postoperative day 28. We concluded that forced treadmill running alleviated persistent postincisional pain caused by SMIR surgery. This appears to be protective against postoperative pain, which probably relates to the downturn in excess SP, interleukin-1β, and interleukin-6 in the DRG. Controlling the expression of SP, interleukin-6, and interleukin-1β in the DRG can help manage postoperative pain. This finding could potentially help clinicians and physical therapists who seek to examine how exercise may attenuate postsurgical pain and its mechanism. Copyright © 2014 American Pain Society.

Traumeel S® for pain relief following hallux valgus surgery: a randomized controlled trial

PubMed Central

2010-01-01

Background In spite of recent advances in post-operative pain relief, pain following orthopedic surgery remains an ongoing challenge for clinicians. We examined whether a well known and frequently prescribed homeopathic preparation could mitigate post-operative pain. Method We performed a randomized, double blind, placebo-controlled trial to evaluate the efficacy of the homeopathic preparation Traumeel S® in minimizing post-operative pain and analgesic consumption following surgical correction of hallux valgus. Eighty consecutive patients were randomized to receive either Traumeel tablets or an indistinguishable placebo, and took primary and rescue oral analgesics as needed. Maximum numerical pain scores at rest and consumption of oral analgesics were recorded on day of surgery and for 13 days following surgery. Results Traumeel was not found superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial, however a transient reduction in the daily maximum post-operative pain score favoring the Traumeel arm was observed on the day of surgery, a finding supported by a treatment-time interaction test (p = 0.04). Conclusions Traumeel was not superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial. A transient reduction in the daily maximum post-operative pain score on the day of surgery is of questionable clinical importance.

Severe pain and high-dose opioids are both associated with increased risk of postoperative delirium. The authors investigated whether parecoxib-supplemented IV morphine analgesia could decrease the incidence of delirium in elderly patients after total hip or knee replacement surgery. In a randomized, double-blind, 2-center trial, patients of 60 years or older who underwent elective total hip or knee replacement surgery were assigned in a 1:1 ratio to receive either parecoxib (40 mg at the end of surgery and then every 12 hours for 3 days) or placebo (normal saline). All patients received combined spinal-epidural anesthesia during surgery and IV morphine for postoperative analgesia. The primary outcome was the incidence of delirium within 5 days after surgery. Between January 2011 and May 2013, 620 patients were enrolled and were included in the intention-to-treat and safety analyses. The incidence of delirium was significantly reduced from 11.0% (34/310) with placebo to 6.2% (19/310) with parecoxib (relative risk 0.56, 95% confidence interval 0.33-0.96, P = .031). The severity of pain and the cumulative consumptions of morphine at 24, 48, and 72 hours after surgery were significantly lower with parecoxib than with placebo (all P < .001), although the differences were small. There was no difference in the incidence of postoperative complications between the 2 groups (12.3% [38/310] with placebo versus 11.6% [36/310] with parecoxib; P = .80). For low-risk elderly patients undergoing elective total hip or knee replacement surgery, multidose parecoxib supplemented to IV morphine decreased the incidence of postoperative delirium without increasing adverse events.

Optimising postoperative pain management in the ambulatory patient.

Shang, Allan B; Gan, Tong J

Over 60% of surgery is now performed in an ambulatory setting. Despite improved analgesics and sophisticated drug delivery systems, surveys indicate that over 80% of patients experience moderate to severe pain postoperatively. Inadequate postoperative pain relief can prolong recovery, precipitate or increase the duration of hospital stay, increase healthcare costs, and reduce patient satisfaction. Effective postoperative pain management involves a multimodal approach and the use of various drugs with different mechanisms of action. Local anaesthetics are widely administered in the ambulatory setting using techniques such as local injection, field block, regional nerve block or neuraxial block. Continuous wound infusion pumps may have great potential in an ambulatory setting. Regional anaesthesia (involving anaesthetising regional areas of the body, including single extremities, multiple extremities, the torso, and the face or jaw) allows surgery to be performed in a specific location, usually an extremity, without the use of general anaesthesia, and potentially with little or no sedation. Opioids remain an important component of any analgesic regimen in treating moderate to severe acute postoperative pain. However, the incorporation of non-opioids, local anaesthetics and regional techniques will enhance current postoperative analgesic regimens. The development of new modalities of treatment, such as patient controlled analgesia, and newer drugs, such as cyclo-oxygenase-2 inhibitors, provide additional choices for the practitioner. While there are different routes of administration for analgesics (e.g. oral, parenteral, intramuscular, transmucosal, transdermal and sublingual), oral delivery of medications has remained the mainstay for postoperative pain control. The oral route is effective, the simplest to use and typically the least expensive. The intravenous route has the advantages of a rapid onset of action and easier titratibility, and so is recommended for the treatment of acute pain.Non-pharmacological methods for the management of postoperative pain include acupuncture, electromagnetic millimetre waves, hypnosis and the use of music during surgery. However, further research of these techniques is warranted to elucidate their effectiveness in this indication. Pain is a multifactorial experience, not just a sensation. Emotion, perception and past experience all affect an individual's response to noxious stimuli. Improved postoperative pain control through innovation and creativity may improve compliance, ease of delivery, reduce length of hospital stay and improve patient satisfaction. Patient education, early diagnosis of symptoms and aggressive treatment of pain using an integrative approach, combining pharmacotherapy as well as complementary technique, should serve us well in dealing with this complex problem.

Carprofen provides better post-operative analgesia than tramadol in dogs after enucleation: A randomized, masked clinical trial

Objective To compare analgesia provided by carprofen or tramadol in dogs after enucleation. Design Randomized, masked trial Animals Forty-three dogs Procedures Client-owned dogs admitted for routine enucleation were randomly assigned to receive either carprofen or tramadol orally 2 hours prior to surgery and 12 hours after the first dose. Dogs were scored for pain at baseline, and postoperatively at 0.25, 0.5, 1, 2, 4, 6, 8, 24, and 30 hours after extubation. Dogs received identical premedication and inhalation anesthesia regimens, including premedication with hydromorphone. If the total pain score was ≥9, if there was a score ≥ 3 in any one category, or if the visual analog scale score (VAS) was ≥35 combined with a palpation score of >0, rescue analgesia (hydromorphone) was administered and treatment failure was recorded. Characteristics between groups were compared with a Student’s t-test and Fisher’s exact test. The incidence of rescue was compared between groups using a log rank test. Pain scores and VAS scores between groups were compared using repeated measures ANOVA. Results There was no difference in age (p=0.493), gender (p=0.366) or baseline pain scores (p=0.288) between groups. Significantly more dogs receiving tramadol required rescue analgesia (6/21) compared to dogs receiving carprofen (1/22; p=0.035). Pain and VAS scores decreased linearly over time (p=0.038, p<0.001, respectively). There were no significant differences in pain (p=0.915) or VAS scores (p=0.372) between groups at any time point (dogs were excluded from analysis after rescue). Conclusions and Clinical Relevance This study suggests that carprofen, with opioid premedication, provides more effective post-operative analgesia than tramadol in dogs undergoing enucleation.

In literature, only a few studies have prospectively compared the results of laparoscopic with open inguinal hernia repair yet none have compared bilateral inguinal hernia repair. The aim of this study is to compare the open Lichtenstein repair (OLR) with laparoscopic trans-abdominal preperitoneal (TAPP) repair in patients undergoing surgery for bilateral inguinal hernia. Patients were prospectively randomized between March 2013 and March 2015. Outcome parameters included hospital stay, operation time, postoperative complications, immediate postoperative pain and chronic pain, recurrence and quality of life. Sixty-one patients underwent TAPP repair and 73 underwent OLR. TAPP procedure had less early post-operative pain up to 7 days from surgery (p = 0.003), a shorter length of hospital stay (p = 0.001), less postoperative complications (p = 0.012) and less chronic pain (0.04) when compared with the OLR approach. TAPP procedure for bilateral inguinal hernia effectively reduces early postoperative pain, hospital stay and postoperative complications. Copyright © 2017 Elsevier Inc. All rights reserved.

We carried out a study to evaluate the effects of protective premedication with Acetaminophen, Gabapentin and combination of Acetaminophen with Gabapentin on post-operative analgesia in patients undergoing open cholecys-tectomy under general anesthesia. PATIENTS #ENTITYSTARTX00026; The study was conducted in a double-blind randomized and controlled manner in 120 consenting patients of either sex belonging to ASA physical status grade I and II, between the age groups of 20 to 50 years, weighing between 40 to 65 kg and undergoing elective surgery (open cholecystectomy) under general anesthesia. The patients were divided into 4 groups: 1: placebo, 2: Acetaminophen 1000 mg, 3: 1200 mg Gabapentin, 4: Acetaminphen 1000 mg plus 1200 mg Gabapentin. The drugs were given two hours before induction. Time, number and total amount of rescue analgesic (tramadol) and VAS score at rest and on movement. Side effects like any episode of nausea/vomiting and level of sedation were noted. Premedication with antihyperalgesic and analgesic agents helps to decrease postoperative pain scores. Gabapentin premedication is effective for providing better postoperative pain relief with lower and delayed requirements of rescue analgesics, but causes more episodes of nausea and vomiting and higher levels of sedation.

The aim of this study was to compare the effect of intravenous paracetamol and tramadol in relieving of postoperative pain after general anesthesia for nephrectomy in prospective donor patients for kidney transplantation. A randomized study was conducted on 100 adult patients scheduled for nephrectomy aged from 35 to 55 years of both sexes and divided into two groups and were administered intravenous paracetamol and tramadol for postoperative pain relief and assessed with visual analog scale score and variations in vital parameters to assess extent of pain relief. After statistical interpretation of collected data, the observations were extrapolated. There was a statistically significant difference in the pain intensity scores obtained between the paracetamol and tramadol groups. On the basis of the present study, it is concluded that tramadol due to its lesser onset of action time was superior to paracetamol in providing acute postoperative pain relief.

The aim of this study was to investigate the short-term (24hours) association between postoperative pain and preoperative psychological variables (anxiety, pain catastrophizing and kinesiophobia) in a sample of knee arthroscopy ambulatory surgery. Observational cross-sectional study, conducted with 40 adult subjects who underwent knee arthroscopy in the surgical area of Cantoblanco Hospital (Hospital Universitario La Paz) in Madrid. The fear-avoidance beliefs and anxiety were assessed using validated questionnaires of pain catastrophizing, kinesiophobia and anxiety. Pre and post-surgical pain and perceived disability were evaluated by the Verbal Numeric Scale. Mean age of the sample (22 men and 18 women) was 52.85±14.21 without significant differences between gender. No statistically significant data for the association between variables of kinesiofobia, anxiety and pain catastrophizing and the intensity of perceived pain by the postoperative knee arthroscopy patient were found. Length of surgery in our study has a correlation with the immediate post-surgical pain (r=0.468; P=.002) and there is a relationship between age and pain intensity at 24hours (r=-0.329; P=.038), and between age and perceived disability (r=-0.314; P=.049). An association between catastrophizing and kinesiophobia scales (r=0.337; P=.033) is obtained likewise. In conclusion, preoperative fear-avoidance beliefs like pain anxiety or pain catastrophizing and kinesiophobia were not associated with acute postoperative pain in our study. Analyses of secondary pain related outcomes, however, indicated that reduced time of surgery may contribute to enhance clinical postoperative pain. If confirmed and replicated in larger samples, this may potentially enable clinicians to improve postoperative pain management in future patients. Copyright © 2016 Elsevier España, S.L.U.

Cryotherapy with dynamic intermittent compression for analgesia after anterior cruciate ligament reconstruction. Preliminary study.

PubMed

Murgier, J; Cassard, X

2014-05-01

Cryotherapy is a useful adjunctive analgesic measure in patients with postoperative pain following anterior cruciate ligament (ACL) surgery. Either static permanent compression or dynamic intermittent compression can be added to increase the analgesic effect of cryotherapy. Our objective was to compare the efficacy of these two compression modalities combined with cryotherapy in relieving postoperative pain and restoring range of knee motion after ligament reconstruction surgery. When combined with cryotherapy, a dynamic and intermittent compression is associated with decreased analgesic drug requirements, less postoperative pain, and better range of knee motion compared to static compression. We conducted a case-control study of consecutive patients who underwent anterior cruciate ligament reconstruction at a single institution over a 3-month period. Both groups received the same analgesic drug protocol. One group was managed with cryotherapy and dynamic intermittent compression (Game Ready(®)) and the other with cryotherapy and static compression (IceBand(®)). Of 39 patients, 20 received dynamic and 19 static compression. In the post-anaesthesia recovery unit, the mean visual analogue scale (VAS) pain score was 2.4 (range, 0-6) with dynamic compression and 2.7 (0-7) with static compression (P=0.3); corresponding values were 1.85 (0-9) vs. 3 (0-8) (P=0.16) after 6 hours and 0.6 (0-3) vs. 1.14 (0-3) (P=0.12) at discharge. The cumulative mean tramadol dose per patient was 57.5mg (0-200mg) with dynamic compression and 128.6 mg (0-250 mg) with static compression (P=0.023); corresponding values for morphine were 0mg vs. 1.14 mg (0-8 mg) (P<0.05). Mean range of knee flexion at discharge was 90.5° (80°-100°) with dynamic compression and 84.5° (75°-90°) with static compression (P=0.0015). Dynamic intermittent compression combined with cryotherapy decreases analgesic drug requirements after ACL reconstruction and improves the postoperative recovery of range of knee motion.

The degree of pain following different types of ear-nose-throat surgery varies greatly and must be adjusted on an individual basis. Post-operative pain therapy can be classified into basic pain therapy and additive pain therapy (as needed). Effective pain therapy can lead to lower morbidity and to considerable economic advantages. The subjective pain intensity experienced by patient should be the basis for the dose adaptation and is essential for rapid recovery.

The purpose of this study was to investigate postoperative analgesic effect of ropivacaine administered as main or supplemental injection for the inferior alveolar nerve block (IANB) in patients undergoing lower third molar surgery. The double-blind randomized study comprised 72 healthy patients. All patients received two blocks, the IANB for surgical procedure + IANB after surgery for postoperative pain control, and were divided into three groups: (1) 2 % lidocaine/epinephrine + 1 % ropivacaine, (2) 2 % lidocaine/epinephrine + saline, and (3) 1 % ropivacaine + saline. The occurrence of postoperative pain, pain intensity and analgesic requirements were recorded. Data were statistically analyzed using chi-square, Fisher, and Kruskal-Wallis tests and analysis of variance (ANOVA) with Bonferroni and Tukey correction. Ropivacaine was more successful than lidocaine/epinephrine in obtaining duration of postoperative analgesia, reduction of pain, and analgesic requirements whether ropivacaine was used for surgical block or administered as a supplemental injection after surgery. Ropivacaine (1 %, 2 ml) resulted in effective postoperative analgesia after lower third molar surgery. Since pain control related to third molar surgery requires the effective surgical anesthesia and postoperative analgesia, the use of 1 % ropivacaine could be clinically relevant in a selection of appropriate pain control regimen for both surgical procedure and early postsurgical treatment.

Improving postoperative tonsillectomy pain management in children--a double blinded randomised control trial of a patient analgesia information sheet.

PubMed

Bailey, Lucas; Sun, Jing; Courtney, Mark; Murphy, Paul

2015-05-01

To evaluate paediatric post-tonsillectomy pain management using oxycodone when a specific analgesia information sheet is included with standard postoperative information. Oxycodone information sheets were randomly allocated to half the study children's post-tonsillectomy information pack. The trial was double-blinded to the surgeon, anaesthetist, nursing and administrative staff. Parents and children completed the pain assessment on day 3, 5 and 7. On day 10 the parents completed a questionnaire. A postoperative analgesia information sheet provides for higher satisfaction and knowledge for parents using oxycodone (p<0.001) and children have improved postoperative pain control, most significantly at day 5 (p<0.05). Parent assessment of the child's analgesia was superior with the oxycodone information sheet, most significantly at day 3 and 7 post operatively (p<0.05). There is also a positive correlation between the parents' observed pain score and children's self reported pain score, with a low correlation efficient level observed (p<0.001). Information sheets are useful in education and use of postoperative analgesia. The primary objective to explore the efficacy of the information sheet has proved to be successful in this setting. Given risks of opioid analgesia, it is recommended that postoperative information sheets be given to all parents, to provide for improved analgesia control and safe management of children in the postoperative period.

Many patients still suffer severe acute pain in the postoperative period. Although guidelines for treating acute pain are widely published and promoted, most do not consider procedure-specific differences in pain experienced or in techniques that may be most effective and appropriate for different surgical settings. The procedure-specific postoperative pain management (PROSPECT) Working Group provides procedure-specific recommendations for postoperative pain management together with supporting evidence from systematic literature reviews and related procedures at http://www.postoppain.org The methodology for PROSPECT reviews was developed and refined by discussion of the Working Group, and it adapts existing methods for formulation of consensus recommendations to the specific requirements of PROSPECT. To formulate PROSPECT recommendations, we use a methodology that takes into account study quality and source and level of evidence, and we use recognized methods for achieving group consensus, thus reducing potential bias. The new methodology is first applied in full for the 2006 update of the PROSPECT review of postoperative pain management for laparoscopic cholecystectomy. Transparency in PROSPECT processes allows the users to be fully aware of any limitations of the evidence and recommendations, thereby allowing for appropriate decisions in their own practice setting.

We compared the effectiveness of liposomal bupivacaine to ropivacaine, each as part of multimodal pain management, in total knee arthroplasty (TKA) postoperative pain control. This prospective, double blind study randomized 96 TKA patients into a control group (periarticular injection of ropivacaine, ketorolac, morphine, and epinephrine in saline; 100cc) or an experimental group (periarticular injection of bupivacaine, ketorolac, morphine, and epinephrine in saline; 80cc plus 1.3% liposomal bupivacaine 20cc; total injection 100cc). The postoperative use of narcotics, visual analog pain scores, hours to ambulate 100 feet, and length of hospital stay were recorded. There was no significant difference between the two groups (control N = 49, experiment N = 47) in mean narcotic use per hour, total narcotic use during hospital stay, time to ambulate 100 feet, length of hospital stay, or visual analog score for pain postoperatively. There is no benefit in the use of liposomal bupivacaine compared with ropivacaine for postoperative pain control in TKA. Copyright © 2017 Elsevier Inc. All rights reserved.

2010-01-01

Temporomandibular joint (TMJ) arthroscopy has been reported to be an effective and reliable technique for the treatment of chronic closed lock (CCL) of the TMJ. The purpose of the present study was to evaluate whether the status of the joint surface and the synovial lining directly visualized with arthroscopy could determine postoperative results in patients with CCL of the TMJ. In all, 257 of 500 patients (344 joints) fulfilled the inclusion criteria for CCL of the TMJ. Of these patients, 172 with unilateral TMJ involvement were finally selected for the study. Synovitis and chondromalacia were chosen as the main features for evaluation of the joint surface and synovial lining. Two groups of patients were established: 1) patients with scarce affectation (synovitis grades I-II and chondromalacia grades I-II); and 2) patients with severe affectation (synovitis grades III-IV and/or chondromalacia grades III-IV). Pain and maximal interincisal opening were chosen as dependent variables. All patients were assessed at 1, 3, 6, 12, and 24 months postoperatively. The paired-samples Student's t test was used to compare mean values for pain (using a visual analog scale) and maximal interincisal opening (MIO) both pre- and postoperatively. The Student's t test for unpaired data was applied for the statistical analysis. A P value less than .05 was considered statistically significant. Synovitis grades I-II were arthroscopically observed in 87 (50.58%) patients, whereas synovitis grades III-IV were present in 72 (41.86%) patients. Chondromalacia grades I-II were arthroscopically observed in 66 (38.37%) patients, whereas chondromalacia grades III-IV were present in 54 (31.39%) patients. A statistically significant decrease in pain (P < .001) with a parallel increase in mouth opening (P < .001) after arthroscopy was observed for patients with synovitis I-II, synovitis III-IV, chondromalacia I-II, and chondromalacia III-IV during the whole follow-up period. A significant difference (P = .01) in relation to VAS score was observed between patients with synovitis I-II and patients with synovitis III-IV at month 6 postoperatively. However, this difference did not persist during the rest of the follow-up period, as was the case in relation to mouth opening. No significant differences were observed in relation to decrease of pain and increase of MIO between patients with chondromalacia I-II and patients with chondromalacia III-IV at any time during the follow-up period. Although mean values for pain were lower in patients with synovitis I-II plus chondromalacia I-II in comparison to patients with synovitis III-IV plus chondromalacia III-IV for the whole follow-up period, no statistical significant differences were observed. In relation to the increase in mouth opening, slightly higher values were observed for patients with synovitis I-II plus chondromalacia I-II, although no statistical differences were observed with regard to patients presenting with synovitis III-IV plus chondromalacia III-IV. A significant decrease in pain with a parallel increase in MIO was achieved from month 1 postoperatively in patients with any grade of synovitis and/or chondromalacia. No statistical difference in pain or function was observed between patients with scarce involvement of the joint surface and the synovial lining and patients with severe involvement after arthroscopy.

Cholelithiasis is very common in patients with sickle cell disease (SCD) and is responsible for recurrent attacks of abdominal pain. The ideal management, especially for children, remains controversial. The purpose of the present study was to evaluate the safety and outcome of mini-laparoscopic cholecystectomy (MLC) in young children under age of 10 years with SCD. A prospective study was carried out of 75 children with SCD under 10 years of age with recurrent abdominal pains seen between August 2001 and March 2004 at Armed Forces Hospital, Khamis Mushayt, Saudi Arabia, who were screened for cholelithiasis. Twelve (16%) of the 75 children were found to have gallstones. The mean age was 7.8 years (range 4-9 years). All 12 children underwent MLC. Anaemia was corrected preoperatively in all the patients. Operative time, intraoperative complications, hospital stay, and postoperative recurrent abdominal pain were recorded. The mean operating time was 46.5 min (range: 35-65 min). Intraoperative cholangiogram failed in two children due to narrow cystic ducts. The mean hospital stay was 2.1 days (range: 2-4 days). No patient required intra-abdominal drain. The mean follow-up period was 13.4 months (range: 4-24 months). The only postoperative complication was deep jaundice 1 month postoperatively due to cholestasis, and this responded to medical treatment. None of the children had recurrent abdominal pain after MLC. Mini-laparoscopic cholecystectomy is a safe surgical procedure for the management of cholelithiasis in children with SCD and leads to improvement in the quality of life by decreasing the frequency of recurrent abdominal pain.

Controversy exists regarding the utility of antecedent venography in percutaneous vertebroplasty. Our purpose was to determine whether antecedent venography improves clinical outcomes and/or decreases extravertebral cement extravasation in these procedures. We retrospective reviewed outcomes of consecutive percutaneous vertebroplasty procedures performed at our institution to define two populations, each consisting of 24 patients treated at 42 vertebral levels. Group 1 included patients who underwent antecedent venography, and group 2 included patients treated without venography. Clinical outcomes were assessed with quantitative measurements of pain and mobility. Venograms and postprocedural radiographs were interpreted to evaluate the number of vertebrae with extravertebral cement extravasation, degree of extravasation at each level, and correlation between venography and vertebroplasty. Pain improved in 19 of 20 group 1 patients, compared with 21 of 22 group 2 patients; mean postoperative pain levels were 1.3 and 1.8, respectively (P =.50), on a scale of 0 (no pain) to 10 (worst pain). All 11 group 1 patients with impaired preoperative mobility reported postoperative improvement, as did all 12 group 2 patients; mean levels of postoperative impaired mobility for groups 1 and 2 were 0.35 and 0.27, respectively (P =.43). Twenty-two of 42 vertebrae treated in group 1 demonstrated extravasation, compared with 28 of 42 in group 2 (P =.266); amounts of extravasation did not differ. Among 22 levels of extravasation in group 1, venograms in 14 showed correlative extravasation. Antecedent venography does not significantly improve the effectiveness or safety of percutaneous vertebroplasty performed by qualified, experienced operators.

In this prospective, observational, 2-armed study, we compared the plasma amino acid profiles of patients undergoing awake craniotomy to those undergoing craniotomy under general anesthesia. Both experimental groups were also compared with a healthy, age-matched and sex-matched reference group not undergoing surgery. It is our intention to investigate whether plasma amino acid levels provide information about physical and emotional stress, as well as pain during awake craniotomy versus craniotomy under general anesthesia. Both experimental groups received preoperative, perioperative, and postoperative dexamethasone. The plasma levels of 20 amino acids were determined preoperative, perioperative, and postoperatively in all groups and were correlated with subjective markers for pain, stress, and anxiety. In both craniotomy groups, preoperative levels of tryptophan and valine were significantly decreased whereas glutamate, alanine, and arginine were significantly increased relative to the reference group. Throughout time, tryptophan levels were significantly lower in the general anesthesia group versus the awake craniotomy group. The general anesthesia group had a significantly higher phenylalanine/tyrosine ratio, which may suggest higher oxidative stress, than the awake group throughout time. Between experimental groups, a significant increase in large neutral amino acids was found postoperatively in awake craniotomy patients, pain was also less and recovery was faster. A significant difference in mean hospitalization time was also found, with awake craniotomy patients leaving after 4.53+/-2.12 days and general anesthesia patients after 6.17+/-1.62 days; P=0.012. This study demonstrates that awake craniotomy is likely to be physically and emotionally less stressful than general anesthesia and that amino acid profiling holds promise for monitoring postoperative pain and recovery.

The surgical removal of the lower third molars is a procedure generally followed by side effects such as postoperative pain. The aim of this study was to evaluate the efficacy of socket irrigation with an anesthetic solution in relieving pain following impacted third molar surgery. Thirty-four patients (17 males and 17 females), aged 18-24 years, with bilateral impacted lower third molars were selected. Both third molars were extracted in one surgical session. Tooth sockets in each patient were rinsed randomly either with 4 mL of 0.5% bupivacaine hydrochloride plain (without vasoconstrictor) anesthetic solu-tion or 4 mL of normal saline, used as control. The patients were instructed not to use analgesics as long as possible, and if not, they were instructed to use an analgesic, and record the time. Pain severity was assessed using a visual analogue pain scale (VAPS) at 1-, 6-, 12-, and 24-hour intervals post-operatively. Data were analyzed using Pearson's chi-square test and P <0.05 was considered statistically significant. Post-operative pain difference between the two groups was statistically significant at 1-, 6-, 12- and 24-hour post-operative intervals (P <0.05). Post-operative pain increased in both groups to a maximum 12 hours after surgery with signif-icant improvements after that. Based on the results, the irrigation of surgery site with bupivacaine after third molar surgery significantly reduces post-operative pain.

The aims of this systematic review were to compare the incidence and intensity of postoperative pain after single-visit root canal treatment using manual, rotary and reciprocating instruments. An extensive literature search in PubMed, EMBASE, Cochrane Library, and Web of Science was performed to identify investigations that evaluated the effects of different instruments on post-endodontic pain. Meta-analyses and additional analyses, including subgroup and sensitivity analyses, were conducted. We included seventeen trials in this study. Pooled results showed that patients treated with rotary instruments experienced a significantly lower incidence of postoperative pain (RR, 0.32, P = 0.0005) and reduced pain intensity than did patients treated with manual instruments. In addition, patients treated with multiple rotary-file systems experienced a significantly lower incidence of postoperative pain than did those treated with reciprocating systems (RR, 0.73; P < 0.0001). The use of rotary instruments contributed to a lower incidence and intensity of postoperative pain than did the use of hand files in patients who received single-visit root canal treatment. In addition, the use of multiple rotary-file systems contributed to a lower incidence of postoperative pain than did the use of reciprocating systems. This article is protected by copyright.

This systematic review examined the efficacy of perioperative nerve blocks for pain control after hip arthroscopy. The databases Embase, PubMed, and Medline were searched on June 2, 2015, for English-language studies that reported on the use of perioperative nerve blocks for hip arthroscopy. The studies were systematically screened and data abstracted in duplicate. Nine eligible studies were included in this review (2 case reports, 2 case series, 3 non-randomized comparative studies, and 2 randomized controlled trials). In total, 534 patients (534 hips), with a mean age of 37.2 years, who underwent hip arthroscopy procedures were administered nerve blocks for pain management. Specifically, femoral (2 studies), fascia iliaca (2 studies), lumbar plexus (3 studies), and L1 and L2 paravertebral (2 studies) nerve blocks were used. All studies reported acceptable pain scores after the use of nerve blocks, and 4 studies showed significantly lower postoperative pain scores acutely with the use of nerve blocks over general anesthesia alone. The use of nerve blocks also resulted in a decrease in opioid consumption in 4 studies and provided a higher level of patient satisfaction in 2 studies. No serious acute complications were reported in any study, and long-term complications from lumbar plexus blocks, such as local anesthetic system toxicity (0.9%) and long-term neuropathy (2.8%), were low in incidence. The use of perioperative nerve blocks provides effective pain management after hip arthroscopy and may be more effective in decreasing acute postoperative pain and supplemental opioid consumption than other analgesic techniques.

The purpose was to investigate risk factors for postoperative stiffness and long-term outcome following manipulation under anaesthesia (MUA). In one of the five Danish regions, all patients in a 4-year period who received MUA following total knee arthroplasty (N=36) were included in two case-control studies. Data on potential risk factors were extracted from the Danish Knee arthroplasty Register and from a postal questionnaire including long-term outcome measures regarding pain, function and quality of life (Oxford Knee Score and EQ-5D). Previous knee surgery and a high preoperative Knee Society Function Score were significant risk factors, whereas attending a preoperative information meeting was associated with a significantly decreased risk of postoperative stiffness requiring MUA (P<0.001). The long-term results following MUA (1-5 years) were equivalent to patients without postoperative stiffness. Copyright © 2013 Elsevier Inc. All rights reserved.

To evaluate the influence of atipamezole on postoperative pain scores in cats. Controlled, randomized, masked clinical trial. Twelve healthy female domestic cats. Cats admitted for ovariohysterectomy (OVH) surgery were randomly allocated to group atipamezole (n = 6) or group saline (n = 6) and were premedicated with buprenorphine 20 μg kg(-1) intramuscularly (IM) and alfaxalone 3.0 mg kg(-1) subcutaneously (SC). Anaesthesia was induced with alfaxalone intravenously (IV) to effect and maintained with isoflurane in oxygen. Ten minutes after extubation, cats from group atipamezole received IM atipamezole (0.0375 mg kg(-1) ) whereas group saline received an equivalent volume [0.0075 mL kg(-1) (0.003 mL kg(-1) IM)] of 0.9% saline. A validated multidimensional composite scale was used to assess pain prior to premedication and postoperatively (20 minutes after extubation). If postoperative pain scores dictated, rescue analgesia consisting of buprenorphine and meloxicam were administered. Pain score comparisons were made between the two groups using a Mann-Whitney exact test. Results are reported as the median and range. Preoperatively, all cats scored 0. At the postoperative pain evaluation, the pain scores from group atipamezole [16 (range, 12-20)] were not significantly different from group saline [18 (range, 15-23)] (p = 0.28). All cats required rescue analgesia post-operatively. Atipamezole (0.0375 mg kg(-1) IM) administration did not significantly affect the postoperative pain scores in cats after OVH. Preoperative administration of buprenorphine (20 μg kg(-1) IM) did not provide adequate postoperative analgesia for feline OVH. © 2016 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

Consensus statement on the anticipation and prevention of acute postoperative pain: multidisciplinary RADAR approach.

There has been considerable investment in efforts to improve postoperative pain management, including the introduction of acute pain teams. There have also been a number of guidelines published on postoperative pain management and there is widespread agreement on how pain should be practically managed. Despite these advances, there is no apparent improvement in the number of patients experiencing moderately severe or extreme pain after surgery. This highlights significant scope for improvement in acute postoperative pain management. In January 2009, a multidisciplinary UK expert panel met to define and agree a practical framework to encourage implementation of the numerous guidelines and fundamentals of pain management at a local level. The panel recognised that to do this, there was a need to organise the information and guidelines into a simplified, accessible and easy-to-implement system based on their practical clinical experience. Given the volume of literature in this area, the Chair recommended that key international guidelines from professional bodies should be distributed and then reviewed during the meeting to form the basis of the framework. Consensus was reached by unanimous agreement of all ten participants. This report provides a framework for the key themes, including consensus recommendations based upon practical experience agreed during the meeting, with the aim of consolidating the key guidelines to provide a fundamental framework which is simple to teach and implement in all areas. Key priorities that emerged were: Responsibility, Anticipation, Discussion, Assessment and Response. This formed the basis of RADAR, a novel framework to help pain specialists educate the wider care team on understanding and prioritising the management of acute pain. Acute postoperative pain can be more effectively managed if it is prioritised and anticipated by a well-informed care team who are educated with regard to appropriate analgesic options and understand what the long-term benefits of pain relief are. The principles of RADAR provide structure to help with training and implementation of good practice, to achieve effective postoperative pain management.

Postoperative pain due to tissue damage caused during surgery not only causes discomfort for the patients, but can also result in prolonged hospitalization, increased morbidity and respiratory disorders, and readmission to the hospital. For postoperative pain control, numerous methods and medications have been suggested, such as non-steroidal anti-inflammatory drugs (NSAIDs) and narcotics. Pethidine, as a narcotic analgesic, and ketorolac, as an NSAID, are widely used for pain control. Thus, in this study, the effects of these two drugs were studied and compared in terms of pain control after inguinal hernia surgery in children of 1-12 years of age. Sixty-six children undergoing inguinal herniorrhaphy were selected and randomly divided into 2 groups. The first group received 0.5 mg/kg ketorolac and the second group received 1 mg/kg pethidine during extubation. Postoperative pain (using Wong Baker pain scale) and complications were measured until 24 hours after surgery. Mean and standard deviations of postoperative pain 1 hour after surgery in the pethidin and ketorolac groups were 5.06 ± 1.41 and 3.88 ± 0.93, respectively. The scale was significantly lower in the ketorolac group (P < 0.001). Postoperative pain intensity 2 hours after surgery in these two groups was 4.48 ± 1.52 and 3.55 ± 1.15, respectively, and the difference between the two groups was significant (P = 0.006). The variation in postoperative pain intensity in the ketorolac group was statistically lower than the pethidin group (P = 0.020). CONCLUSION.

Background: Effective management of postoperative pain is a part of well-organized perioperative care, which helps in reduced morbidity and improved patient satisfaction. Preventive analgesia can reduce acute and chronic pain by blocking the noxious inputs to pain pathways, preventing sensitization. Studies have reported efficacy of gabapentin as a preventive analgesic in perioperative pain. In this study, we aimed to determine whether preoperative gabapentin reduced postoperative pain and tramadol consumption after thyroidectomy under general anesthesia. Materials and Methods: Sixty patients scheduled for thyroidectomy were allocated to two groups of thirty each for this prospective, observational study. Patients in Group A and Group B received oral gabapentin 600 mg (6 × 10−4 kg) and diazepam 10 mg (1 × 10−5 kg), respectively, 2 h prior to surgery. Tramadol was given as rescue analgesic for postoperative pain with a verbal rating score of two. The analgesic efficacy of preoperative gabapentin was assessed in terms of postoperative pain scores at rest or swallowing, time to first rescue analgesic, and total tramadol consumption for 24 h. Ramsay sedation score and side effects of drug were also looked into. Results: Postoperative pain scores and total tramadol consumption were significantly lower in Group A during 24 h (P = 0.00). Time to first rescue analgesic was significantly prolonged in Group A (P = 0.001). Side effects were comparable. Conclusion: Oral gabapentin is effective as a preventive analgesic in reducing postoperative pain and tramadol consumption after thyroidectomy under general anesthesia. PMID:28928577

After haemorrhoidectomy the maximum resting pressure (MRP) of the anal canal is significantly increased. This increase play an important role in the making of postoperative pain. Recently, both the topical application of glyceryl trinitrate (GT) and the intrasphincter injection of botulinum toxin (Tox), resulted effective, in reducing temporary the MRP although with different mechanism of action. In this study the effectiveness and safe of contemporary injection of Tox and topical application of 300 mg/die of GT after Milligan-Morgan haemorrhoidectomy, were evaluated. Ten patients, undergoing Milligan-Morgan haemorrhoidectomy for 3rd and 4th degree haemorrhoids are included in this study. In all subjects, preoperatively and after 5 and 40 day following surgery, an ano-rectal manometry was performed. At the end of surgery, in all patients, 0.4 ml of solution containing 20UI of Tox was injected and 100 mg of 0.2% of GT was applied in the anal canal and in the perianal wounds. Afterwards the patients has been instructed to apply 100 mg of GT three times daily, for seven days. Time of perianal wounds healing, of first defecation, to return to work, of duration of surgery, of hospital stay, the complications, postoperative pain either on resting or during defecation, the analgesic consumption and side effects were recordered. On the 5th and 40th postoperative day, the MRP resulted significantly reduced as compared to preoperative values. Postoperative pain either on resting or during defecation was higher on the 1st assessment, afterwards it progressively decreased. Anal incontinence was observed only in two patients, whereas headache only in one case. The contemporary intrasphincter injection of Tox and perianal application of 300 mg/die of GT is safe and effective, with an incidence of complications similar to those detected when this drugs are given alone.

Major shoulder surgery is associated with moderate-to-severe pain, but consensus on the optimal analgesic approach is lacking. Continuous catheter-based interscalene block (CISB) prolongs the analgesic benefits of its single-injection counterpart (SISB), but concerns over CISB complications and difficulties in interpreting comparative evidence examining major and minor shoulder procedures simultaneously, despite their differences in postoperative pain, have limited CISB popularity. This meta-analysis evaluates the CISB analgesic role and complications compared with SISB for major shoulder surgery. We retrieved randomised controlled trials (RCTs) comparing the effects of CISB to SISB on analgesic outcomes and side-effects after major shoulder surgery. Postoperative opioid consumption at 24 h was designated as the primary outcome. Secondary outcomes included 24-48 h opioid consumption, postoperative rest and dynamic pain scores up to 72 h, time-to-first analgesic, recovery room and hospital stay durations, patient satisfaction, postoperative nausea and vomiting, respiratory function, and block-related complications. Data from 15 RCTs were pooled using random-effects modelling. Compared with SISB, CISB reduced 24- and 48-h oral morphine consumption by a weighted mean difference [95% confidence interval] of 50.9 mg [-81.6, -20.2], (P=0.001) and 44.7 mg [-80.9, -8.7], (P<0.0001), respectively. Additionally, CISB provided superior rest and dynamic pain control beyond 48 h, prolonged time-to-first analgesic, enhanced satisfaction, and reduced postoperative nausea and vomiting without complications. CISB caused an 11.0-11.7% decrease in respiratory indices. Result heterogeneity was successfully explained. High-level evidence indicates that CISB provides superior analgesia up to 48 h after major shoulder surgery, without increasing side-effects, compared with SISB. The importance of CISB-related changes in respiratory indices is questionable. Copyright © 2017 British Journal of Anaesthesia. Published by Elsevier Ltd. All rights reserved.

Kassim, Dina Y.; Esmat, Ibrahim M.; Elgendy, Mohammed A.

2018-01-01

Background: Patients’ surgical experiences are influenced by their perception of pain management. Duloxetine (Dulox) and dexamethasone (Dex) are used in multimodal analgesia to reduce opioid use and side effects. Dulox is a selective serotonin and norepinephrine reuptake inhibitor and has efficacy in chronic pain conditions. Dex enhances postoperative (PO) analgesia and reduces PO nausea and vomiting (PONV). Methods: Seventy-five female patients were randomly allocated into one of three equal groups. GI received Dulox 60 mg orally and 100 ml 0.9% sodium chloride (normal saline [NS]) intravenous infusion (IVI) over 15 min, GII: received as GI except Dex 0.1 mg/kg was mixed with NS and GIII received identical placebo for Dulox capsule and Dex IVI, 2 h preoperatively. Patients’ vitals, visual analog scale (VAS), and sedation score were assessed at 30 min, 1 h, 2 h, 6 h, and 12 h postoperatively. Total pethidine requirements, plasma cortisol, PONV, and patients satisfaction were recorded. Results: PO time for 1st rescue analgesic was significantly high in GI and GII compared to GIII and in GII compared to GI. There was a significant less VAS score, heart rate, mean arterial pressure, and a high sedation score in GI and GII compared to GIII at 30 min, 1, 2, and 6 h postoperatively. Total pethidine requirements were significantly less in GI and GII compared to GIII 12 h postoperatively. There was a significant reduction in the 2 h PO serum cortisol (μg/dl) and a significant increase in the PO patients satisfaction score in GI and GII compared to GIII. PONV was decreased significantly in GII compared to GI and GIII. Conclusion: The use of oral Dulox 60 mg combined with Dex 0.1 mg/kg IVI is more effective than oral Dulox 60 mg alone, 2 h preoperatively, for improving PO pain by reducing the requirements for rescue analgesia and PONV.

Cannabinoids have dose-related antinociceptive effects in animals. This clinical study aimed to investigate whether a single oral dose of cannabis plant extract (Cannador; Institute for Clinical Research, IKF, Berlin, Germany) could provide pain relief with minimal side effects for postoperative pain. Patients (aged 18-75 yr) were recruited and consented before surgery if patient-controlled analgesia was planned for provision of postoperative pain relief. Each patient received a single dose of 5, 10, or 15 mg Cannador if he or she had at least moderate pain after stopping patient-controlled analgesia. Starting with 5 mg, dose escalation was based on the number of patients requesting rescue analgesia and adverse effects. Pain relief, pain intensity, and side effects were recorded over 6 h and analyzed using tests for trend with dose. Rescue analgesia was requested by all 11 patients (100%) receiving 5 mg, 15 of 30 patient (50%) receiving 10 mg, and 6 of 24 patients (25%) receiving 15 mg Cannador (log rank test for trend in time to rescue analgesia with dose P < 0.001). There were also significant trends across the escalating dose groups for decreasing pain intensity at rest (P = 0.01), increasing sedation (P = 0.03), and more adverse events (P = 0.002). The number needed to treat to prevent one rescue analgesia request for the 10-mg and 15-mg doses, relative to 5 mg, were 2.0 (95% confidence interval, 1.5-3.1) and 1.3 (95% confidence interval, 1.1-1.7), respectively. The study was terminated because of a serious vasovagal adverse event in a patient receiving 15 mg. These significant dose-related improvements in rescue analgesia requirements in the 10 mg and 15 mg groups provide a number needed to treat that is equivalent to many routinely used analgesics without frequent adverse effects.

This prospective, randomized study compared postoperative pain control with use of a continuous temperature-controlled cryotherapy system versus a traditional ice therapy regimen following outpatient knee arthroscopy. Patients with unilateral knee pathology scheduled for outpatient arthroscopic surgery were included. Patients with major ligament reconstructions were excluded. A specific cold therapy regimen was begun postoperatively and continued for 2 weeks as adjunctive management of postoperative pain. Preoperative and postoperative pain intensity, pain type, functionality, and sleep quality were assessed. Patients were randomly assigned to either an ice or a continuous cryotherapy group. Follow-up questionnaires were completed on 5 postoperative days. Data were analyzed using a chi-square test with a level of significance at P < 0.05. Fifty-three patients completed the study. Pain intensity was similar between groups throughout the course of the study. Among patients who reported experiencing night pain, 36% of those in the continuous cryotherapy group were able to sleep soundly with minimal awakening through postoperative day 2 versus 5.9% among the ice therapy group (P = 0.04). No significant differences existed between groups regarding functional ability, and no differences were noted on other follow-up days. These findings support use of continuous temperature-controlled cold therapy devices for nighttime pain control and improved quality of life in the early period following routine knee arthroscopy.

It has not been established whether sex differences in pain perception are influenced by prenatal sex hormones. Digit ratio as an indicator of prenatal hormone exposure can be used as a simple measure of the influence of prenatal hormones on pain sensitivity or perception in adulthood. The aim of this study was to determine a correlation between the 2D:4D ratio and pain perception in the postoperative period after rhinoplasty. A prospective cohort study of 100 patients (50 women of the mean age of 30.74±8.09years and 50 men of the mean age of 30.98±10.86years) who underwent posttraumatic rhinoplasty due to the nose trauma in Plastic, Reconstructive and Aesthetic Surgery Clinic. The following measurements were taken the day before a surgery: body height, waist and hip circumference, II and IV digits' lengths and body weight. All subjects filled in a questionnaire including 0-10-point VAS scales to assess postoperative pain 1h after an operation (AO), 6h AO, 12h AO, 24h AO and 48h AO. Women with low 2D:4D reported significantly more pain 1h after an operation than women with high 2D:4D. Similar correlation was observed for low 2D:4D in women 48h AO. In men, low 2D:4D was associated with lower postoperative pain 12h AO (p=0.029). In conclusion, we showed that low 2D:4D in women was associated with high postoperative pain, and low right 2D:4D in men was associated with low postoperative pain. This may suggest that intrauterine estrogen exposure makes women more resistant to pain. Copyright © 2017 Elsevier B.V. All rights reserved.

Burmaster, Chris; Eckenrode, Brian J; Stiebel, Matthew

2016-01-01

Both traditional and progressive rotator cuff repair rehabilitation protocols often delay active motion of the shoulder for 6 weeks or more. The early inclusion of a comprehensive aquatic-assisted exercise program presents a unique approach to postoperative management. The purpose of this case study is to describe a comprehensive evidence-based, aquatic-assisted rehabilitation program following arthroscopic rotator cuff repair. A 73-year-old woman with a nonretracted, medium-size, full-thickness tear (2.5 cm) of the supraspinatus tendon underwent arthroscopic rotator cuff repair and was referred for postoperative physical therapy. The rehabilitation program was initiated at 2 weeks postoperatively and consisted of concurrent land- and aquatic-based interventions over 6 weeks for a total of 18 physical therapy visits. Improvements were made in all 5 patient-reported outcome measures that were recorded weekly over the course of care. Improvements reached or exceeded minimal detectable change levels for the Shoulder Pain and Disability Index and the Penn Shoulder Score. Her numeric pain rating scale score at rest decreased from 4/10 at the initial evaluation to 2/10 at 8 weeks postoperatively and with activity decreased from 9/10 to 6/10. Shoulder strength and range of motion values also exhibited improvement over the course of care. No adverse events occurred during the case study. This case study illustrates the safe inclusion of low-stress aquatic exercises as an early adjunct to traditional land-based rotator cuff repair rehabilitation programs in small- to medium-size repairs. Further studies are needed to determine the long-term effectiveness of adding aquatic therapy to traditional postoperative programs. © 2016 American Physical Therapy Association.

While a large number of studies has examined the efficacy of opioid-sparing analgesics in adult surgical populations, fewer studies are available to guide postoperative pain treatment in pediatric patients. We systematically reviewed available publications on the use of systemic nonopioid agents for postoperative analgesia in pediatric surgical populations. A comprehensive literature search identified meta-analyses and randomized controlled trials (RCTs) assessing the effects of systemic, nonopioid agents on postoperative narcotic requirements or pain scores in pediatric surgical populations. If a meta-analysis was located, we summarized its results and any RCTs published after it. We located and reviewed 11 acetaminophen RCTs, 1 nonsteroidal anti-inflammatory drug (NSAID) meta-analysis, 2 NSAID RCTs, 1 dexamethasone meta-analysis, 3 dexamethasone RCTs, 2 ketamine meta-analyses, 5 ketamine RCTs, 2 gabapentin RCTs, 1 clonidine meta-analysis, 3 magnesium RCTs, 2 dexmedetomidine meta-analyses, and 1 dextromethorphan RCT. No meta-analyses or RCTs were found assessing the perioperative efficacy of intravenous lidocaine, amantadine, pregabalin, esmolol, or caffeine in pediatric surgical patients. The available evidence is limited, but suggests that perioperative acetaminophen, NSAIDs, dexamethasone, ketamine, clonidine, and dexmedetomidine may decrease postoperative pain and opioid consumption in some pediatric surgical populations. Not enough, or no, data exist from which to draw conclusions on the perioperative use of gabapentin, magnesium, dextromethorphan, lidocaine, amantadine, pregabalin, esmolol, and caffeine in pediatric surgical patients. Further pharmacokinetic and pharmacodynamics studies to establish both the clinical benefit and efficacy of nonopioid analgesia in pediatric populations are needed.

Poor postoperative pain control is frequently associated with complications and delayed discharge from a hospital. Preemptive analgesia is one of the methods suggested for reducing postoperative pain. Opioids are effective for pain control, but there known addictive properties make physicians cautious about using them. Parecoxib and ketorolac are potent non-opioid NSAIDs that are attractive alternative drugs to opioids to avoid opioid-related side effects. However, there are no good head-to-head comparisons between these two drugs in the aspect of preemptive analgesic effects in lumbar spinal fusion surgery. This study aimed to compare the efficacy in terms of postoperative pain control and safety of parecoxib with ketorolac as preemptive analgesia in posterior lumbar spinal fusion patients. A prospective, double-blinded randomized controlled trial was carried out in patients undergoing posterior lumbar spinal fusion, who were randomized into 3 groups (n = 32). Parecoxib, ketorolac or a placebo was given to each patient via injection around 30 minutes prior to incision. The efficacy of postoperative pain control was assessed by a verbal numerical rating score (0-10). And various postoperative things were monitored for analysis, such as total opioid consumption, complications, and estimated blood loss. Both the ketorolac and parecoxib groups showed significantly better early postoperative pain reduction at the postanesthesia care unit (PACU) than the control group (p < 0.05). There were no differences between the pain scores of ketorolac and parecoxib at any time points. Complications and bleeding were not significantly different between all three groups. Preemptive analgesia using both ketorolac and parecoxib showed a significantly better early postoperative pain control in the PACU than the control group in patients undergoing lumbar spinal fusion.

The purpose of this study was to compare the results of thoracic epidural analgesia (TEA) and parecoxib in controlling postoperative pain after the Nuss procedure. Between August 2005 and July 2014, 120 adolescents and adults underwent Nuss procedures and received either TEA or parecoxib for postoperative pain control. Demographic data, preoperative preparation times, visual analog scale (VAS) pain scores from postoperative day 1 to day 5, medical costs of pain control, days to Foley catheter removal, days to being able to sit up, days to being able to walk, days of hospital stay, nausea/vomiting scores, and complications related to pain control were compared. A total of 106 patients received TEA, and 14 received parecoxib. No between-group differences in demographics were observed. Patients in the parecoxib group had shorter preparation times (p<0.001), lower VAS pain scores from postoperative day 2 to day 5 (day 2, p=0.006; day 3, p=0.006; day 4, p<0.001; day 5, p<0.001), shorter hospital stays (p<0.001), lower pain control costs (p<0.001), and lower nausea/vomiting scores (p=0.046). For adolescents and adults undergoing the Nuss procedure, parecoxib affords better pain control efficacy, a shorter hospital stay, lower medical pain control costs, and fewer side effects compared with TEA.

Many patients undergoing anaesthesia and surgery experience postoperative complications. Our aim was to investigate whether a systematic follow-up smartphone-based assessment, using recovery assessment by phone points (RAPP) compared with standard care, had a positive effect on day surgery patients' postoperative recovery. We also investigated whether there were differences in women and men's recovery and recovery scores. The study was a single-blind, multicentre randomized controlled trial. A total of 997 patients were randomly allocated to either RAPP or standard care. The Swedish web version of a quality of recovery (SwQoR) questionnaire was used to evaluate the patients' postoperative recovery, either on paper or using an application (RAPP) on postoperative days seven and 14. On postoperative day seven the RAPP group reported significantly better values in seven out of 24 items of the SwQoR: sleeping difficulties; not having a general feeling of wellbeing; having difficulty feeling relaxed/comfortable; and dizziness; headache; pain in the surgical wound; and a swollen surgical wound compared with the control group, implying a good postoperative recovery. Both men and women in the RAPP group reported significantly better values (and, hence good postoperative recovery) compared with the control group in the items sleeping difficulties; not having a general feeling of wellbeing and pain in the surgical wound. Measurement of patient-reported outcomes using a smartphone-based application was associated with decreased discomfort from several postoperative symptoms. Systematic e-assessment can thereby increase patients' quality of recovery and identify key areas for improvement in perioperative care. NCT02492191. © The Author 2017.

The aim of this study was to examine pain and quality of life in a group of preoperative chronic low back pain patients (n = 25) and a group of postoperative chronic low back pain patients (n = 101) treated with instrumented fusion 1-8 years ago. Reduced quality of life is common in chronic low back pain patients and the aim of treatment is to improve quality of life. In the present study, a comparative survey design was used. The McGill Pain Questionnaire and the SF-36 Health Survey were used to examine pain and quality of life. The pre- and postoperative groups did not differ with regard to age, gender, education, other chronic conditions or previous spinal surgery. Compared with the preoperative group, the postoperative group reported significantly lower total, sensory, affective and evaluative pain, used less pain medication (p < 0.05) and reported better scores in all SF-36 components (p < 0.05), except for general health. The effect size was > or =0.8 for all pain components and > or =0.4 for all SF-36 components, except for general health (effect size = 0.009). With regard to long-term follow-up, patients who underwent surgery 5-8 years ago reported better physical role functioning (p < 0.05) compared with those who underwent surgery 1-2 years ago. Results showed that the postoperative group reported significantly less pain and better physical and mental health compared with the preoperative group. However, despite surgery, the postoperative group reported suffering from pain and reduced quality of life. Relevance to clinical practice. Psychosocial interventions focusing on psychosocial consequences of pain are needed to modify the pain experience and increase the quality of life in patients who have undergone this kind of surgery.

Purpose/Aim: Lumbar degenerative diseases (LDDs) cause pain and disability and are treated with lumbar fusion surgery. The aim of this study was to evaluate the efficacy of lumbar fusion surgery with ISOBAR devices versus posterior lumbar interbody fusion (PLIF) surgery for alleviating LDD-associated pain and disability. We performed a literature review and meta-analysis conducted in accordance with Cochrane methodology. The analysis included Group Reading Assessment and Diagnostic Evaluation assessments, Jadad Quality Score evaluations, and Risk of Bias in Non-randomized Studies of Interventions assessments. We searched PubMed, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, ProQuest, the Airiti Library, and the China Academic Journals Full-text Database for relevant randomized controlled trials and cohort studies published in English or Chinese between 1997 and 2017. Outcome measures of interest included general pain, lower back pain, and disability. Of the 18 studies that met the inclusion criteria, 16 examined general pain (802 patients), 5 examined lower back pain (274 patients), and 15 examined disability (734 patients). General pain, lower back pain, and disability scores were significantly lower after lumbar fusion surgery with ISOBAR devices compared to presurgery. Moreover, lumbar fusion surgery with ISOBAR devices was more effective than PLIF for decreasing postoperative disability, although it did not provide any benefit in terms of general pain or lower back pain. Lumbar fusion surgery with ISOBAR devices alleviates general pain, lower back pain, and disability in LDD patients and is superior to PLIF for reducing postoperative disability. Given possible publication bias, we recommend further large-scale studies.

To identify the effects of cryotherapy on patient discomfort following craniotomy. Following craniotomy, many patients suffer from unexpected discomfort, including pain, eyelid oedema and ecchymosis. Cryotherapy is regarded as a safe method for managing these postcraniotomy problems. Randomised controlled trial. A total of 97 Korean patients who underwent elective supratentorial craniotomy were randomly assigned to a cryotherapy or a control group. In the cryotherapy group, ice bags were applied to surgical wounds, and cold gel packs were applied to periorbital areas, for 20 minutes per hour, beginning three hours postoperatively and for three days thereafter. The level of patient pain was measured using the visual analogue scale while the eyelid oedema was measured using the Kara & Gokalan's scale. Ecchymosis was also classified according to its extent. The level of pain three hours after craniotomy was similar in the cryotherapy and control groups (57.9 vs. 58.7). Three days after surgery, pain had significantly decreased in the cryotherapy group (p = 0.021). After adjusting diagnosis by analysis of covariance (ANCOVA), pain score did not differ significantly between the two groups. The mean eyelid oedema scores were lower in the cryotherapy group than in the control group (0.59 vs. 2.29, p < 0.001), with ANCOVA showing that cryotherapy had a significant effect on eyelid oedema (p < 0.001). Pain (p = 0.047) and eyelid oedema (p < 0.001) in the cryotherapy group were significantly decreased over time. Ecchymosis were significantly less frequent in the cryotherapy (11/48, 22.9%) than in the control (26/49, 53.1%) group (p = 0.003). Logistic regression analysis showed that cryotherapy affected ecchymosis (p = 0.001). These results indicate that cryotherapy can control pain, eyelid oedema and facial ecchymosis after craniotomy. Cryotherapy, which is both convenient and cost-effective, can be used to prevent postoperative discomforts in a clinical setting.

Objective  Rectus muscle reapproximation at cesarean delivery (CD) is performed frequently by some obstetricians; however, the effect on postoperative pain is unclear. To this end, we investigated whether rectus muscle reapproximation increases postoperative pain. Materials and Methods  This is a prospective, double-blind, randomized controlled trial of women undergoing primary CD with singleton or twin pregnancy at >35 weeks' gestation. Women were randomized to rectus muscle reapproximation with three interrupted sutures or no reapproximation. Exclusion criteria were prior cesarean, prior laparotomy, vertical skin incision, active labor, chronic analgesia use, allergy to opioid or nonsteroidal anti-inflammatory drugs, and body mass index ≥ 40. Intra- and postoperative pain management was standardized within the study protocol. The primary outcome was a combined movement pain and opioid use score averaged over the 72-hour study period, called the Silverman integrated assessment. Movement pain scores were assessed at 24, 48, and 72 postoperative hours. Results  In total, 63 women were randomized, of whom 35 underwent rectus muscle reapproximation and 28 did not. Demographic and obstetric variables were similar between groups. Silverman integrated assessment scores during the 72-hour postoperative period were higher in the rectus muscle reapproximation group (15 ± 100% vs. –31 ± 78% difference from the mean; p  = 0.04). Operative times were similar between groups (63 ± 15 vs. 65 ± 15 minutes; p  = 0.61), and there were no surgical complications in either group. Maternal satisfaction with analgesia at 72 hours was high in both groups (85% [73–90] rectus muscle reapproximation vs. 90% [75–100]; p  = 0.16). Conclusion  Rectus muscle reapproximation increased immediate postoperative pain without differences in operative time, surgical complications, or maternal satisfaction. Benefits of rectus muscle reapproximation should be weighed against increased postoperative pain, and analgesia should be planned accordingly. PMID:28840194

Local anesthetic infiltration and corticosteroids had shown effectiveness in reducing post tonsillectomy nausea, vomiting and pain. To compare the effect of intravenous dexamethasone versus pre-incision infiltration of local anesthesia in pediatric tonsillectomy on postoperative nausea and vomiting (PONV). The secondary objective was postoperative pain. A randomized double-blind clinical trial was conducted at a tertiary care teaching hospital. Children admitted to undergo tonsillectomy aged between 4 and 13 years from January 2015 to August 2015 were enrolled and divided into two groups. Both groups had general anesthesia. Group I received intravenous dexamethasone 0.5 mg/kg (maximum dose 16 mg) with placebo pre-incision infiltration. Group II received pre-incision infiltration a total of 2-4 ml local anesthesia mixture with saline and an equivalent volume of intravenous saline. Group I consisted of 64 patients while group II had 65 patients. In the PACU, 15.6% of patients in group I experienced vomiting compared to 3.1% in group II (p-value = 0.032). After 24 h, the incidence of PONV was significantly higher in group I compared to group II (26.6% vs. 9.2% respectively, p-value = 0.019). At 48 h postoperatively, PONV was significantly higher in group I (p-value = 0.013). The incidence was similar in both groups after three, four and five postoperative days. Baseline pain and pain during swallowing were significantly different at 6, 12 and 24 h as well as days 1 through 5. Pain upon jaw opening was significantly different at 6, 12 and 24 h between the two groups. Pain while eating soft food was significantly different at 24 h and days 2 through 5. In the PACU, 20.3% of patients in group I received diclofenac compared to 3.1% in group II (p-value = 0.005). From day 1 till day 5, analgesic consumption was significantly higher in group I. Local anesthetic infiltration in addition to NSAIDS and paracetamol could serve as a multimodal analgesia and decrease PONV. NCT02355678. Copyright © 2016. Published by Elsevier Ireland Ltd.

Introduction Residual pain is a major factor in patient dissatisfaction following total hip arthroplasty or total knee arthroplasty (THA/TKA). The proportion of patients with unfavourable long-term residual pain is high, ranging from 7% to 34%. There are studies indicating that a preoperative degree of central sensitisation (CS) is associated with poorer postoperative outcomes and residual pain. It is thus hypothesised that preoperative treatment of CS could enhance postoperative outcomes. Duloxetine has been shown to be effective for several chronic pain syndromes, including knee osteoarthritis (OA), in which CS is most likely one of the underlying pain mechanisms. This study aims to evaluate the postoperative effects of preoperative screening and targeted duloxetine treatment of CS on residual pain compared with care-as-usual. Methods and analysis This multicentre, pragmatic, prospective, open-label, randomised controlled trial includes patients with idiopathic hip/knee OA who are on a waiting list for primary THA/TKA. Patients at risk for CS will be randomly allocated to the preoperative duloxetine treatment programme group or the care-as-usual control group. The primary end point is the degree of postoperative pain 6 months after THA/TKA. Secondary end points at multiple time points up to 12 months postoperatively are: pain, neuropathic pain-like symptoms, (pain) sensitisation, pain catastrophising, joint-associated problems, physical activity, health-related quality of life, depressive and anxiety symptoms, and perceived improvement. Data will be analysed on an intention-to-treat basis. Ethics and dissemination The study is approved by the local Medical Ethics Committee (METc 2014/087) and will be conducted according to the principles of the Declaration of Helsinki (64th, 2013) and the Good Clinical Practice standard (GCP), and in compliance with the Medical Research Involving Human Subjects Act (WMO).

This study sought methods in burn surgery to reduce postoperative pain and blood loss at donor sites. A prospective, randomised, controlled, blinded trial included 56 people undergoing burn surgery, divided into two groups. Both groups received subcutaneous infiltration at donor sites, with either 1:500,000 adrenaline solution containing added lidocaine or with 0.45% normal saline (controls). Outcome measurements included amount of intraoperative bleeding, need for electrocautery, days the hydrocolloid dressing remained on donor sites, percentage of re-epithelialised skin at donor sites 1 week after surgery and viability of skin grafts. Results indicated that subcutaneous adrenaline-lidocaine infiltration at donor sites reduced intraoperative bleeding, decreased postoperative pain, shortened the duration of surgery and general anaesthesia and accelerated re-epithelialisation at the donor site. The overall graft take in both groups was similar.

Pain may be associated with postoperative cognitive dysfunction (POCD); however, this relationship remains under investigated. Therefore, we examined the impact of postoperative pain on cognitive functions in aged animals. Rats were allocated to the following groups: control (C), 1.2 % isoflurane for 2 hours alone (I), I with laparotomy (IL), IL with analgesia using local ropivacaine (IL+R), and IL with analgesia using systemic morphine (IL+M). Pain was assessed by rat grimace scale (RGS). Spatial memory was evaluated using a radial maze from postoperative days (POD) 3 to 14. NMDA receptor (NR) 2 subunits in hippocampus were measured by ELISA. Finally, effects of memantine, a low-affinity uncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist, on postoperative cognitive performance were tested. Postoperative RGS was increased in Group IL, but not in other groups. The number of memory errors in Group I were comparable to that in Group C, whereas errors in Group IL were increased. Importantly, in Group IL+R and IL+M, cognitive impairment was not found. The memory errors were positively correlated with the levels of NMDA receptor 2 subunits in hippocampus. Prophylactic treatment with memantine could prevent the development of memory deficits observed in Group IL without an analgesic effect. Postoperative pain contributes to the development of memory deficits after anesthesia and surgery via up-regulation of hippocampal NMDA receptors. Our findings suggest that postoperative pain management may be important for the prevention of POCD in elderly patients. Copyright © 2013 Elsevier Inc. All rights reserved.

Even though the use of a 25 gauge or smaller Quincke needle is recommended for spinal anesthesia to reduce post-dural puncture headache in Korea, lumbar puncture in older patients using a 25 gauge or smaller Quincke needle can be difficult. However, most previous studies concerning post-dural puncture headache have chosen children, parturients, and young adults as study participants. The study compared post-dural puncture headache, post-operative back pain, and the number of lumbar puncture attempts using a 23 or 25 gauge Quincke needle for spinal anesthesia of Korean patients >60-years-of-age. Randomized, double-blinded controlled trial. The 53 participants who underwent orthopedic surgery under spinal anesthesia were recruited by informed notices from December 2006 through August 2007 at a 200-bed general hospital located in Kyunggido. Inclusion criteria were an age >60 years, ASA I-II, and administration of patient controlled analgesia for the first 48 h post-operatively. The 53 patients were randomly allocated to either the experimental (23 gauge Quincke needle) or control group (25 gauge Quincke needle). All patients had 24 h bed rest post-operatively. Post-dural puncture headache was assessed by the Dittmann Scale and post-operative back pain was assessed by a visual analogue scale at 24, 48, and 72 h post-operatively. The statistical methods included the Mann-Whitney U-test and Spearman correlation. There were no differences in post-dural puncture headache, and post-operative back pain at 24, 48, and 72 h post-operatively, and no differences in the number of lumbar punctures, with the 23 and 25 gauge Quincke needle. Forty-eight hour post-operative back pain was positively associated with the number of lumbar punctures (p=.036) and age (p=.040). There were no statistically significant associations among post-dural puncture headache, the number of lumbar punctures, and 48 h post-operative back pain. Pre-operative back pain was positively associated with 48 h post-operative back pain (p<.001). The choice of a 23 or 25 gauge Quincke needle for spinal anesthesia has no significant influence on post-dural puncture headache and post-operative back pain for Korean patients greater than 60-years-of-age. The 23 gauge Quincke needle is an option for lumbar punctures in this patient population. Copyright © 2011 Elsevier Ltd. All rights reserved.

Appropriate pain management affects outcome after hip fracture surgery. Although multimodal pain management is commonly used for pain control for patients undergoing elective surgery, few studies have evaluated its use in those undergoing hip fracture surgery. This prospective randomized study was designed to determine the clinical value of multimodal pain management with preemptive pain medication and intraoperative periarticular multimodal drug injections in patients undergoing bipolar hip hemiarthroplasty. Of eighty-two cognitively intact elderly patients about to undergo bipolar hemiarthroplasty after a hip fracture, forty-three were randomly assigned to receive preemptive pain medication and intraoperative periarticular injections (Group I) and thirty-nine were assigned to not receive preemptive medication and injections (Group II). These two groups were compared with regard to the pain level on postoperative days one, four, and seven; at discharge; and when they started walking and standing exercises. Total amounts of fentanyl used, the frequency of use of patient-controlled analgesia, patient satisfaction at discharge, and perioperative complications were recorded. Group I had a lower pain level than Group II on postoperative days one and four, but no intergroup difference in pain level was observed on postoperative day seven. The total amount of fentanyl used and the frequency of use of patient-controlled analgesia were also lower in Group I. Patient satisfaction at discharge was higher in Group I. No significant intergroup differences were found in the times until the patients walked or performed standing exercises or in the complications. Multimodal pain management provides additional pain relief until the fourth postoperative day, improves patient satisfaction at discharge, and reduces total narcotic consumption for postoperative pain management after hip hemiarthroplasty for hip fractures.

Abstract Introduction: Pain management after surgery continues to be suboptimal; there are several reasons including lack of translation of results from basic science studies and scientific clinical evidence into clinical praxis. Objectives: This review presents and discusses basic science findings and scientific evidence generated within the last 2 decades in the field of acute postoperative pain. Methods: In the first part of the review, we give an overview about studies that have investigated the pathophysiology of postoperative pain by using rodent models of incisional pain up to July 2016. The second focus of the review lies on treatment recommendations based on guidelines and clinical evidence, eg, by using the fourth edition of the “Acute Pain Management: Scientific Evidence” of the Australian and New Zealand College of Anaesthetists and Faculty of Pain Medicine. Results: Preclinical studies in rodent models characterized responses of primary afferent nociceptors and dorsal horn neurons as one neural basis for pain behavior including resting pain, hyperalgesia, movement-evoked pain or anxiety- and depression-like behaviors after surgery. Furthermore, the role of certain receptors, mediators, and neurotransmitters involved in peripheral and central sensitization after incision were identified; many of these are very specific, relate to some modalities only, and are unique for incisional pain. Future treatment should focus on these targets to develop therapeutic agents that are effective for the treatment of postoperative pain as well as have few side effects. Furthermore, basic science findings translate well into results from clinical studies. Scientific evidence is able to point towards useful (and less useful) elements of multimodal analgesia able to reduce opioid consumption, improve pain management, and enhance recovery. Conclusion: Understanding basic mechanisms of postoperative pain to identify effective treatment strategies may improve patients' outcome after surgery. PMID:29392204

Acetaminophen is effective for acute surgical pain, but whether it reduces persistent incision pain remains unknown. We tested the primary hypothesis that patients given perioperative acetaminophen have less incisional pain three months after surgery. Our secondary hypotheses were that patients randomized to acetaminophen have less postoperative pain and analgesic consumption, and better functional recovery at three months. 140 patients having abdominal hysterectomy were randomly assigned to: 1)intravenous acetaminophen (4 g/day for 72 postoperative hours); or, 2) saline placebo. The primary outcome was incisional pain visual analog scale (VAS) at three months after surgery. The secondary outcomes were (1, 2) postoperative VAS scores while laying and sitting and (3) total patient-controlled intravenous tramadol consumption during the initial 24 hours, (4) DN4 questionnaires and (5) SF-12 at three months after surgery. The persistent incisional pain scores at three months were significantly lower in acetaminophen (median [Q1, Q3]: 0 [0, 0]) as compared with saline group (0 [0, 1]) (P = 0.002). Specifically, 89%, 9%, and 2% of acetaminophen patients with VAS pain score at three months of 0, 1, and 2 or more, as compared with 66%, 23%, and 10% in the saline group (odds ratio: 2.19 (95% CI: 1.33, 3.59), P = 0.002). Secondly, postoperative pain scores both laying and sitting were significantly lower in the acetaminophen group. Acetaminophen group had significantly better DN4 score and mental health related but not physical health related quality of life. Our results suggest that acetaminophen reduces the risk and intensity of persistent incisional pain. However, there are other mechanisms by which acetaminophen might reduce persistent pain.

Some patients experience severe pain following root canal therapy (RCT) despite advancements in care. We sought to identify factors, which can be measured preoperatively, that predict this negative outcome so that future research may focus on preemptive steps to reduce postoperative pain intensity. Sixty-two practitioners (46 general dentists and 16 endodontists) who are members of the National Dental Practice-Based Research Network enrolled patients receiving RCT for this prospective observational study. Baseline data collected from patients and dentists were obtained before treatment. Severe postoperative pain was defined based on a rating of ≥7 on a scale from 0 (no pain) to 10 (pain as bad as can be) for the worst pain intensity experienced during the preceding week, and this was collected 1 wk after treatment. Multiple logistic regression analyses were used to develop and validate the model. A total of 708 patients were enrolled during a 6-m period. Pain intensity data were collected 1 wk postoperatively from 652 patients (92.1%), with 19.5% (n = 127) reporting severe pain. In multivariable modeling, baseline factors predicting severe postoperative pain included current pain intensity (odds ratio [OR], 1.15; 95% confidence interval [CI], 1.07 to 1.25; P = 0.0003), number of days in the past week that the subject was kept from their usual activities due to pain (OR, 1.32; 95% CI, 1.13 to 1.55; P = 0.0005), pain made worse by stress (OR, 2.55; 95% CI, 1.22 to 5.35; P = 0.0130), and a diagnosis of symptomatic apical periodontitis (OR, 1.63; 95% CI, 1.01 to 2.64; P = 0.0452). Among the factors that did not contribute to predicting severe postoperative pain were the dentist’s specialty training, the patient’s age and sex, the type of tooth, the presence of swelling, or other pulpal and apical endodontic diagnoses. Factors measured preoperatively were found to predict severe postoperative pain following RCT. Practitioners could use this information to better inform patients about RCT outcomes and possibly use different treatment strategies to manage their patients (Clinicaltrials.gov NCT01201681).

Practical physicians do not have instruments for objective pain assessment despite recent advances of neurophysiology and pain pharmacology. The article deals with the study of relations between preoperative pain sensitivity (finger prick and venipuncture) and pain level after surgery. 60 patients involved in the study were divided into two groups. Pain sensitivity was assessed in all patients by visual analogue scale before surgery, after awaking, in 1 hour and in 3 hours after awaking and in 1 day after the surgery. Psychological status of patients was assessed by integration anxious test, neurotic disorders questionnaire and type of attitude to the disease questionnaire. All patients were assessed by 70 criteria (54 psychological). Results of the study show that postoperative pain syndrome is affected by different psychophysiological factors. Therefore it is difficult to forecast the level of postoperative pain syndrome.

Background and Objectives The goal of this meta-analysis study was to assess the effects of fentanyl on emergence agitation (EA) under sevoflurane anesthesia in children. Subjects and Methods We searched electronic databases (PubMed, Embase, Web of Science and the Cochrane Central Register of Controlled Trials) for articles published until December 2014. Randomized controlled trials (RCTs) that assessed the effects of fentanyl and placebo on EA under sevoflurane anesthesia in children that the outcome were the incidence of EA, postoperative pain, emergence time or adverse effects were included in this meta-analysis. Results A total of 16 studies, including 1362 patients (737 patients for the fentanyl group and 625 for the placebo group), were evaluated in final analysis. We found that administration of fentanyl decreased the incidences of EA (RR = 0.37, 95% CI 0.27~0.49, P<0.00001) and postoperative pain (RR = 0.59, 95% CI 0.41~0.85, P = 0.004) but increased the incidence of postoperative nausea and vomiting (PONV) (RR = 2.23, 95% CI 1.33~3.77, P = 0.003). The extubation time (WMD = 0.71 min, 95% CI 0.12~1.3, P = 0.02), emergence time (WMD = 4.90 min, 95% CI 2.49~7.30, P<0.0001), and time in the postanesthesia care unit (PACU) (WMD = 2.65 min, 95% CI 0.76~4.53, P = 0.006) were slightly increased. There were no significant differences in the time to discharge of day patients (WMD = 3.72 min, 95% CI -2.80~10.24, P = 0.26). Conclusion Our meta-analysis suggests that fentanyl decreases the incidence of EA under sevoflurane anesthesia in children and postoperative pain, but has a higher incidence of PONV. Considering the inherent limitations of the included studies, more RCTs with extensive follow-up should be performed to validate our findings in the future. PMID:26275039

Acute pain is a significant problem in the postoperative setting. Patients report a lack of information about pain-control measures and ineffective pain control. Nurses continue to rely on pharmacologic measures and tend to under-administer analgesics. The purpose of this study was to determine the strategies nurses used to manage patients' pain in the postoperative setting. It also sought to examine the effect of context, including organization of care, nurses' prioritization of work activities, and pressures during a working shift, on their pain-management strategies. An observational design was used in two surgical units of a metropolitan teaching hospital in Melbourne, Australia. Six fixed observation times were identified as key periods for pain activities, each comprising a 2-hour duration. An observation period was examined at least 12 times, resulting in the completion of 74 observations and the identification of 316 pain cases. Fifty-two nurses were observed during their normal day's work with postoperative patients. Six themes were identified: managing pain effectively; prioritizing pain experiences for pain management; missing pain cues for pain management; regulators and enforcers of pain management; preventing pain; and reactive management of pain. The findings highlighted the critical nature of communication between clinicians and patients and among clinicians. It also demonstrated the influence of time on management strategies and the relative importance that nurses place on nonpharmacologic measures in actual practice. This research, which portrays what happens in actual clinical practice, has facilitated the identification of new data that were not evident from other research studies.

AIM: To investigate the effect of pain relief after infusion of ropivacaine at port sites at the end of surgery. METHODS: From October 2006 to September 2007, 72 patients undergoing laparoscopic cholecystectomy (LC) were randomized into two groups of 36 patients. One group received ropivacaine infusion at the port sites at the end of LC and the other received normal saline. A visual analog scale was used to assess postoperative pain when the patient awakened in the operating room, 6 and 24 h after surgery, and before discharge. The amount of analgesics use was also recorded. The demographics, laboratory data, hospital stay, and perioperative complications were compared between the two groups. RESULTS: There was no difference between the two groups preoperatively in terms of demographic and laboratory data. After surgery, similar operation time, blood loss, and no postoperative morbidity and mortality were observed in the two groups. However, a significantly lower pain score was observed in the patients undergoing LC with local anesthesia infusion at 1 h after LC and at discharge. Regarding analgesic use, the amount of meperidine used 1 h after LC and the total used during admission were lower in patients undergoing LC with local anesthesia infusion. This group also had a shorter hospital stay. CONCLUSION: Local anesthesia with ropivacaine at the port site in LC patients significantly decreased postoperative pain immediately. This explains the lower meperidine use and earlier discharge for these patients. PMID:19452582

The goal of this study was to evaluate the outcome of Tension-free Vaginal Tape Obturator (TVT-O) operation in the treatment of urodynamic stress incontinence (USI) in obese females, with respect to uroflowmetric changes, success rate and postoperative complications. This prospective observational study included 26 patients with USI at the Obstetrics & Gynecology department-Cairo University hospital during the year 2015. The participants had body mass index (BMI)≥30. Patients underwent TVT-O operation. Follow up of the patients was performed by cough test and uroflowmetry after one week, one month, three months and six months. Postoperative complications such as groin pain, sense of incomplete emptying, need to strain to complete micturition and urinary tract infection were recorded. Comparisons between groups were done using Chi square, Phi-Cramer test for categorical variables. The mean age for the subjects was 43.58±9.01years. The mean BMI was 33.4±2.1. The success rate of TVT-O operation was 21 out of 26 patients (≈81%). Normal maximum flow rate was in 88% of patients at week one and was normal in 100% of patients at months three and six (p=0.101 & 0.101). Postoperative groin pain was the main complaint during the first week after operation and decreased significantly from week one to the 1st month postoperative (84.62% & 65.38%, P=0.041). TVT-O operation showed a high success rate in treatment of USI in obese patients without affecting the voiding function of the bladder as proven by the uroflowmetry. The main postoperative complaint was the groin pain which significantly improved after one month. Copyright © 2017 Elsevier B.V. All rights reserved.

Although placement of a retropubic mid-urethral slings (MUS) is one of the gold standard surgical treatments for stress urinary incontinence, new devices are poorly evaluated before marketing. We compared TVT-EXACT™ (TVT-E), a new device expected to reduce bladder injuries, with the historically described bottom-to-top TVT™ (TVT). This retrospective study compared TVT-E (n=49) and TVT (n=49). The main outcomes were the prevalence of complications (bladder injuries, immediate postoperative pain, perioperative complications, etc.) and the short-term success rate (no reported urinary leakage and negative cough test) of both MUSs. Minimum follow-up was 12 months. The characteristics of the two groups were comparable. The prevalence of bladder injury for TVT-E and TVT was 8% and 6%, respectively (p=1). The intensity of immediate postoperative pain (VAS/100) was lower following TVT-E than after TVT (8.0 vs. 15.9, p=0.01). The first post-void residual was increased in the TVT-E group (153.9 vs. 78.9mL, p=0.045), and there were more postoperative bladder outlet obstruction (BOO) symptoms in the TVT-E group (24% vs. 6%, p=0.02). However, there was no difference when considering only de novo BOO (14% vs. 4%, p=0.16). The prevalence of peri- and post-operative complications was equal in the two groups. The success rate was similar at 12 months of follow-up (80 vs. 82%, p=1). The prevalence of bladder injury was unchanged with TVT-EXACT™ compared with TVT™, but post-operative pain was decreased. The success rate of both retropubic MUSs was similar at 12 months of follow-up. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

One of the major advantages for patients undergoing minimally invasive surgery as compared to an open surgical procedure is the improved recovery profile and decreased opioid requirements in the perioperative period. There are no definitive studies comparing the analgesic requirements in patients undergoing two different types of minimally invasive procedure. This study retrospectively compares the perioperative analgesic requirements in severely obese adolescents and young adults undergoing laparoscopic versus robotic-assisted, laparoscopic gastric sleeve resection. With Institutional Review Board approval, the medication administration records of all severely obese patients who underwent gastric sleeve resection were retrospectively reviewed. Intra-operative analgesic and adjuvant medications administered, postoperative analgesic requirements, and visual analog pain scores were compared between those undergoing a laparoscopic procedure versus a robotic-assisted procedure. This study cohort included a total of 28 patients who underwent gastric sleeve resection surgery with 14 patients in the laparoscopic group and 14 patients in the robotic-assisted group. Intra-operative adjuvant administration of both intravenous acetaminophen and ketorolac was similar in both groups. Patients in the robotic-assisted group required significantly less opioid during the intra-operative period as compared to patients in the laparoscopic group (0.15 ± 0.08 mg/kg vs. 0.19 ± 0.06 mg/kg morphine, P = 0.024). Cumulative opioid requirements for the first 72 postoperative h were similar in both the groups (0.64 ± 0.25 vs. 0.68 ± 0.27 mg/kg morphine, P = NS). No difference was noted in the postoperative pain scores. Although intraoperative opioid administration was lower in the robotic-assisted group, the postoperative opioid requirements, and the postoperative pain scores were similar in both groups.

Abstract This study aimed to report our institution's experience in the diagnosis and treatment of chronic lateral ankle instability (CLAI) with ligamentum bifurcatum (LB) injury. This retrospective study included 218 consecutive patients with CLAI who underwent surgery from January 2012 to December 2015. The 218 patients received tendon allograft reconstruction of the lateral ligament. CLAI was combined with LB injury in 51.4% (112/218) of patients. The 112 patients with concurrent LB injury had this treated simultaneously; 36 patients underwent excision of the anterior process of the calcaneus, 68 underwent LB repair, and 8 underwent LB reconstruction. Patients returned for a clinical and radiologic follow-up evaluation at an average of 31 (range, 24–35) months postoperatively. Outcomes were assessed by comparison of pre- and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) scores, visual analog scale pain scores, Karlsson scores, and radiographic assessment. Of the patients with concurrent LB injury, 82.1% (92/112) returned for final evaluation. Postoperatively, most patients recovered very well. However, the outcome was not ideal in those who underwent excision of the anterior process of the calcaneus; there were significant postoperative decreases in talar tilt (P < .05) and anterior drawer (P < .05), but there was no significant postoperative improvement in visual analog scale pain score and AOFAS score. Patients who underwent LB repair or reconstruction had an excellent or good outcome regarding patient subjective self-assessment, pain scores, Karlsson scores, and AOFAS scores at final follow-up. Patients with CLAI often have concurrent LB injury. The diagnosis of LB injury can be missed or delayed. Clinicians should closely examine the LB in cases of CLAI, and should surgically repair or reconstruct the LB when necessary. PMID:29489650

All patient data was collected in a prospective way in four study centres. Both preoperative and postoperative evaluation consisted of an assessment using the AOFAS-HMI score, visual analogue scale for pain, evaluation of the range of motion and patient satisfaction scores. Postoperative X-rays were reviewed for loosening and radiolucency up to two years. Fifty-five feet were available for analysis at 24 months. Two implants were removed during the study. Six more feet had additional surgery due to stiffness or malalignment. Postoperative AOFAS-HMI scores improved significantly by 32.4 points at two year follow-up (p<0.001). The visual analogue scale for pain improved significantly from 6.8 (std 1,6) preoperatively to 1.6 (std 1,9) postoperatively (p<0.0001). Mean dorsiflexion improved from 12.6 (std 10,1) degrees preoperatively to 31.2 (std 16,8) degrees postoperatively. Eighty-seven percent of patients were moderately to well satisfied with the end result. Eighteen prostheses showed radiolucency at 24 months. Implantation of a Metis ® modular three component press fit prosthesis for the metatarsophalangeal joint in hallux rigidus shows significant improvement in AOFAS-HMI scores and a decrease in pain. Concerns remain with regard to early reoperation rate (14.5%) and long term survival of the implant. Future studies will have to address these aspects.

Total knee arthroplasty is associated with substantial postoperative pain that may impair mobility, reduce the ability to participate in rehabilitation, lead to chronic pain, and reduce patient satisfaction. Traditional general anesthesia with postoperative epidural and patient-controlled opioid analgesia is associated with an undesirable adverse-effect profile, including postoperative nausea and vomiting, hypotension, urinary retention, respiratory depression, delirium, and an increased infection rate. Multimodal anesthesia--incorporating elements of preemptive analgesia, neuraxial perioperative anesthesia, peripheral nerve blockade, periarticular injections, and multimodal oral opioid and nonopioid medications during the perioperative and postoperative periods--can provide superior pain control while minimizing opioid-related adverse effects, improving patient satisfaction, and reducing the risk of postoperative complications.

PAIN OUT is a European Commission-funded project aiming at improving postoperative pain management. It combines a registry that can be useful for quality improvement and research using treatment and patient-reported outcome measures. The core of the project is a patient questionnaire-the International Pain Outcomes questionnaire-that comprises key patient-level outcomes of postoperative pain management, including pain intensity, physical and emotional functional interference, side effects, and perceptions of care. Its psychometric quality after translation and adaptation to European patients is the subject of this validation study. The questionnaire was administered to 9,727 patients in 10 languages in 8 European countries and Israel. Construct validity was assessed using factor analysis. Discriminant validity assessment used Mann-Whitney U tests to detect mean group differences between 2 surgical disciplines. Internal consistency reliability was calculated as Cronbach's alpha. Factor analysis resulted in a 3-factor structure explaining 53.6% of variance. Cronbach's alpha at overall scale level was high (.86), and for the 3 subscales was low, moderate, or high (range, .53-.89). Significant mean group differences between general and orthopedic surgery patients confirmed discriminant validity. The psychometric quality of the International Pain Outcomes questionnaire can be regarded as satisfactory. The International Pain Outcomes questionnaire provides an instrument for postoperative pain assessment and improvement of quality of care, which demonstrated good psychometric quality when translated into a variety of languages in a large European and Israeli patient population. This measure provides the basis for the first comprehensive postoperative pain registry in Europe and other countries. Copyright © 2013. Published by Elsevier Inc.

A new rehabilitation (New-RH) program including respiratory muscle stretch gymnastics (RMSG) was developed to alleviate post-coronary artery bypass grafting pain (PCP). Effects on respiratory muscle function, pain, activities of daily living (ADL), mood and exercise capacity were investigated. Subjects were 16 consecutive patients undergoing median full sternotomy coronary artery bypass grafting (CABG), and were randomly divided into equal New-RH (S-group) and conventional therapy (C-group) groups. Rib cage dominant breathing was observed postoperatively in both groups. With preoperative tan deltaVrc/deltaVab, increases at 1-week postoperatively and decreases at discharge for S-group tended to exceed those of C-group (p > .05). Decreased maximum inspiratory and expiratory pressure status for functional residual capacity and percent forced expiratory volume in one second at discharge again only tended to be smaller for S-group (p > .05). S-group displayed significantly reduced pain around both scapulas at discharge (p = .049), and increased mean overall ADL and profile of mood states (POMS)/Vigor scores (p = .031 and p = .018, respectively). POMS/Tension-Anxiety scores at discharge for S-group were significantly smaller than those preoperatively (p = .025), and S-group displayed significantly increased distance walked over 6-minutes at discharge than C-group (p = .029). New-RH improves patient participation in exercise therapy and increases exercise capacity by reducing PCP, relieving anxiety and tension, and improving ADL.

Primary management of tonsillar hyperplasia in children is tonsillectomy. Recent data from clinical case-series are clearly in support of the hypothesis that tonsillotomy with the CO2-laser seems to be effective and is noted to have less postoperative bleeding and less pain as compared to tonsillectomy. For the first time we used a monopolar argon-supported needle for tonsillotomy in the following study. Fifty patients (age: 4.58 years; SD +/- 2.33) with benign tonsillar hyperplasia were recruited. For tonsillotomy we used the monopolar argon-supported needle. The outcome measures were postoperative pain, capability of oral intake, consumption of analgesics and postoperative bleeding. No postoperative bleeding occurred. Post-operative pain hardly occurred and could easily be controlled. The third postoperative day analgesics intake was under one portion per day (mean: 0.91; SD +/- 1.26). Capability of oral intake and swallowing was normal on the seventh postoperative day. It was concluded that tonsillotomy, using the monopolar argon-supported needle, is a valid treatment for benign tonsillar hyperplasia in children, which can be performed with slight post-operative pain and a low risk for postoperative bleeding. It offers good dissection and haemostasis abilities. Compared to the CO2-laser the monopolar argon-supported needle does not require any laser safety precautions.

Systems controlling cardiovascular function are closely coupled with the perception of pain. Heart rate variability (HRV) is a well-established noninvasive measure of cardiac autonomic control. We hypothesized that pain may alter HRV in the newborn infant and that HRV analysis could be used as an indicator of prolonged pain in the newborn infant. To test the hypothesis, we measured the magnitude of the heart rate high-frequency variations using an innovative High Frequency Variability Index (HFVI) in newborn infants at risk of postoperative pain. We investigated newborn infants with a gestational age (GA) more than 34 weeks, and who were admitted after a major surgical procedure. Inclusions ranged from 2 to 72 hours after the surgery. The postoperative pain was scored using EDIN scale (neonatal pain and discomfort scale) at the end of the 2 hours recording period. The infants were separated in: (1) Group "Low EDIN," when EDIN<5; and (2) Group "High EDIN," when EDIN >=5. Predictive positive and negative values of a threshold value of HFVI in assessing pain have been studied. Twenty-eight newborn infants were enrolled in the study (mean GA=37.8+/-1.5 wk) at a median delay between the surgery and the recording of 5 hours. Mean EDIN were 2+/-1 and 7+/-2 in respectively the groups "Low EDIN" and "High EDIN." The 2 groups were similar for GA, basal heart and respiratory rates, SpO2, mean arterial blood pressure, and morphine infusion rate. HFVI was significantly lower in the group "High EDIN" than in the group "Low EDIN" (0.7+/-0.2 vs. 1.2+/-0.3, respectively; P<0.01). An HFVI <0.9 was able to predict an EDIN score >=5, with a sensitivity of 90%, and a specificity of 75%. The results of this study indicate that postoperative pain is associated with a decreased high-frequency HRV in full-term newborn infants. Our findings suggest that HRV could be used as an indicator to assess prolonged pain in the newborn infants.

Pain following total hip arthroplasty (THA) and surface arthroplasty (SRA) remains a significant source of patient dissatisfaction. Two hundred twenty-four SRA and 196 THA patients completed a pain drawing questionnaire and postoperative radiographic measurements of component positioning were performed. In the SRA cohort, 11 of 21 patients (52%) with acetabular uncoverage of ≥5 mm versus 43 of 147 (29%) with acetabular uncoverage of ≤4.9 mm reported groin pain (P=.03). In the THA cohort, an increased distal-third canal fill ratio and a lower canal calcar ratio trended towards a higher incidence of thigh pain (P=.10 and .06), while a decreased mid-third canal fill ratio was associated with increased severity of thigh pain (P=.04). This study identifies associations between radiographic findings and pain following THA and SRA. Copyright © 2014 Elsevier Inc. All rights reserved.

There is no widely recognized effective technique to optimally reduce pain scores and prevent persistent postoperative pain after nephrectomy. We compared continuous surgical site analgesia (CSSA), epidural analgesia (EA), and a control group (patient-controlled analgesic morphine) in patients undergoing open nephrectomy. Sixty consecutive patients were randomized to be part of EA, CSSA, or control groups postoperatively for 72 hours. All patients received patient-controlled analgesic morphine, if needed. Hyperalgesia was assessed on the first, second, and third postoperative days. Chronic pain characteristics and quality of life were analyzed at 1 and 3 months. The primary outcome was the pain score at 24 hours. Secondary outcomes were morphine consumption, postoperative rehabilitation, hyperalgesia, chronic pain incidence, and quality-of-life parameters. At 24 hours, mean ± standard deviation pain values at rest (2.4 ± 1.7, 2.2 ± 1.2, and 4.2 ± 1.2, respectively, in EA, CSSA, and control groups, P <.001) and during coughing was lower in the EA and CSSA groups. Total morphine consumption was higher in the control group. Rehabilitation parameters improved sooner in the EA and CSSA groups. Median values of area of hyperalgesia differed at 48 hours between the EA group and the control group (36.4 cm) and (52 cm) (P = .01) and at 72 hours among the EA group, CSSA group, and the control group (40 cm, 39.5 cm, and 59 cm, respectively; P = .002). CSSA reduced the severity of pain and hyperalgesia at 1 month and optimized quality of life 3 months after surgery (role physical scores, P = .005). CSSA and EA significantly improve postoperative analgesia, reduce postoperative morphine consumption, area of wound hyperalgesia, and accelerate patient rehabilitation after open nephrectomy. CSSA significantly reduces the severity of residual pain 1 month after surgery and optimizes quality-of-life parameters 3 months after surgery.

The article presents French guidelines for surgical management of endometriosis. Surgical treatment is recommended for mild to moderate endometriosis, as it decreases pelvic painful complaints and increases the likelihood of postoperative conception in infertile patients (A). Surgery may be proposed in symptomatic patients with ovarian endometriomas which diameter exceeds 20mm. Cystectomy allows for better postoperative pregnancy rates when compared to ablation using bipolar current, as well as for lower recurrences rates when compared to ablation using bipolar current or CO 2 laser. Ablation of ovarian endometriomas using bipolar current is not recommended (B). Surgery may be employed in patients with deep endometriosis infiltrating the colon and the rectum, with good impact on painful complaints and postoperative conception. In these patients, laparoscopic route increases the likelihood of postoperative spontaneous conception when compared to open route. When compared to conservative rectal procedures (shaving or disc excision), segmental colorectal resection increases the risk of postoperative stenosis, requiring additional endoscopic or surgical procedures. In large deep endometriosis infiltrating the rectum (>20mm length of bowel infiltration), conservative rectal procedures do not improve postoperative digestive function when compared to segmental resection. In patients with bowel anastomosis, placing anti-adhesion agents on contact with bowel suture is not recommended, due to higher risk of bowel fistula (C). Various other recommendations are proposed in the text, however, they are based on studies with low level of evidence. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

BACKGROUND: A return toward toward photorefractive keratectomy has occurred due to better corneal stability and fewer corneal flap complications; however, pain remains a major drawback of the procedure. Currently, clinical pain control measures focus on the administration of pain medications, which may delay corneal epithelial healing and has, occasionally, led to serious corneal toxicity. OBJECTIVES: To investigate the safety and efficacy of a cold patch on postoperative pain and other relevant consequences of transepithelial photorefractive keratectomy. METHODS: A prospective, randomized controlled study was conducted. Forty patients (80 eyes) scheduled to undergo transepithelial photorefractive keratectomy for myopia or myopic astigmatism were randomly and equally assigned to be treated with ice-cold balanced salt solution during surgery (wash group) or to wear a postoperative cold patch on the eye for 24 h. The main outcomes were pain score on a visual analogue scale, postoperative eyelid edema, conjunctival hyperemia, epithelial healing time, haze and postoperative best-corrected visual acuity. RESULTS: All patients completed the final tests. Demographic characteristics and pain scores during surgery were similar between the two groups. The mean postoperative pain scores of patients in the cold patch group at 8 h, 16 h and 24 h were significantly lower than those of patients in the wash group. Scores for postoperative eyelid edema and conjunctival hyperemia in the cold patch group were also lower than in the wash group. Patients in the cold patch group used fewer painkillers. Epithelial healing time, haze and early recovery of visual acuity were similar between the two groups. No eyelid frostbite was observed. CONCLUSION: Wearing a cold patch on the eye after transepithelial photorefractive keratectomy effectively relieved pain and inflammation, and reduced the use of painkillers without any side effects.

Background Variance in pain following total knee and hip arthroplasty may be due to a number of procedural and peripheral factors but also, in some individuals, to aberrant central pain processing as is described in conditions like fibromyalgia. To test this hypothesis, we conducted a prospective, observational cohort study of patients undergoing lower extremity joint arthroplasty. Methods 519 patients were preoperatively phenotyped using validated self-reported pain questionnaires, psychological measures, and health information. In addition to assessing factors previously found to be associated with poor outcomes in arthroplasty, participants also completed the American College of Rheumatology survey criteria for fibromyalgia. Previous studies have suggested that rather than being “present” or “absent,” features of fibromyalgia as measured by this instrument, occur over a wide continuum. Postoperative pain control was assessed by total postoperative opioid consumption. Results Preoperatively, patients with higher fibromyalgia survey scores were younger, more likely to be female, taking more opioids, reported higher pain severity, and had a more negative psychological profile. In the multivariate analysis, the fibromyalgia survey score, younger age, preoperative opioid use, knee (vs. hip), pain severity at baseline, and the anesthetic technique were all predictive of increased postoperative opioid consumption. Conclusions Using the survey criteria for fibromyalgia distinct phenotypic differences were found, and the measure was independently predictive of opioid consumption. This self-report measure may provide an additional simple means of predicting postoperative pain outcomes and analgesic requirements. Future studies are needed to determine whether tailored therapies can improve postoperative pain control in this population. PMID:24343289

Purpose Pain rating scales are widely used for pain assessment. Nevertheless, a new tool is required for pain assessment needs in retrospective studies. Methods The postoperative pain episodes, during the first postoperative day, of three patient groups were analyzed. Each pain episode was assessed by a visual analog scale, numerical rating scale, verbal rating scale, and a new tool – pain point system scale (PPSS) – based on the analgesics administered. The type of analgesic was defined based on the authors’ clinic protocol, patient comorbidities, pain assessment tool scores, and preadministered medications by an artificial neural network system. At each pain episode, each patient was asked to fill the three pain scales. Bartlett’s test and Kaiser–Meyer–Olkin criterion were used to evaluate sample sufficiency. The proper scoring system was defined by varimax rotation. Spearman’s and Pearson’s coefficients assessed PPSS correlation to the known pain scales. Results A total of 262 pain episodes were evaluated in 124 patients. The PPSS scored one point for each dose of paracetamol, three points for each nonsteroidal antiinflammatory drug or codeine, and seven points for each dose of opioids. The correlation between the visual analog scale and PPSS was found to be strong and linear (rho: 0.715; P < 0.001 and Pearson: 0.631; P < 0.001). Conclusion PPSS correlated well with the known pain scale and could be used safely in the evaluation of postoperative pain in retrospective studies. PMID:23152699

The low temperature device did not show any advantages over the conventional high temperature electrocautery in terms of the postoperative pain, operation time, and complications in pediatric tonsillectomy. To compare post-tonsillectomy pain following the use of two different instruments with the same bipolar forceps techniques: low temperature quantum molecular resonance (QMR) device versus conventional high temperature electrocautery. Pediatric patients admitted from July 2008 through January 2009 were included. The participants underwent bilateral tonsillectomy; one side by the QMR device and the other by the bipolar electrocautery. The sides for each instrument were counterbalanced by the order of presentation. The postoperative pain was measured using the faces pain rating scale. In all, 33 patients with a mean age of 7.6 years were enrolled. The postoperative pain, operation time, and complications in 33 sides dissected by the electrocautery and 33 sides by the QMR device were compared. The average operation times with each device were not statistically different. The mean ratings of the perception of pain related to each instrument were not different on operation day and postoperative day 1, day 4, and day 7 (p = 0.133, 0.057, 0.625, and 1.0, respectively). There was no postoperative complication in any of the patients.

Using a double-blinded randomized crossover design, this study aimed to evaluate acute postoperative pain management, swelling and trismus in 46 volunteers undergoing extractions of the two lower third molars, in similar positions, at two different appointments who consumed a tablet of either NE (naproxen 500 mg + esomepraz ole 20 mg) or only naproxen (500 mg) every 12 hours for 4 days. Parameters were analyzed: self-reported pain intensity using a visual analog scale (VAS) pre- and postoperative mouth opening; incidence, type and severity of adverse reactions; total quantity consumed of rescue medication; and pre- and postoperative swelling. Female volunteers reported significantly more postoperative pain at 1, 1.5, 2, 3 and 4hrs after surgery while also taking their first rescue medication at a time significantly earlier when consuming NE when compared to naproxen (3.7hrs and 6.7hrs). Conversely, no differences were found between each drug group in males. In conclusion, throughout the entire study, pain was mild after using either drug in both men and women with pain scores on average well below 40mm (VAS), although in women naproxen improved acute postoperative pain management when compared to NE.

A retrospective study of postoperative pain management. Evaluate the efficacy and safety of continuous intravenous morphine infusion for postoperative pain management in patients with idiopathic scoliosis (IS) undergoing posterior spinal fusion (PSF) and segmental spinal instrumentation (SSI). Postoperative pain is a common problem following surgery for IS. There are no published reports regarding the use of a continuous intravenous morphine infusion for this patient population. We retrospectively reviewed data regarding 339 consecutive patients with IS who underwent PSF and SSI between 1992 and 2006. All patients received intrathecal morphine after the induction of general anesthesia. Following surgery, preordered morphine infusion (0.01 mg/kg/h) was started at first reported pain. The infusion rate was titrated based on vital signs, visual analog scale (VAS) pain scores (0-10), and clinical status. It was continued until patients were able to take oral analgesics. We reviewed intrathecal morphine dosage, VAS pain scores through the third postoperative day, interval to start of morphine infusion, total morphine requirements in the first 48 hours, and any adverse reactions (nausea/vomiting, pruritus, respiratory depression, and pediatric intensive care unit admission). Mean intrathecal morphine dose was 15.5 +/- 3.9 microg/kg and mean interval to start of the intravenous morphine infusion was 17.5 +/- 5 hours. Mean VAS pain scores were 3.1, 4.5, 4.5, and 4.6 at 12 hours, 1, 2, and 3 days after surgery, respectively.The total mean morphine dose in the first 48 hours postoperatively was 0.03 +/- 0.01 mg/kg/h. Total morphine received was 1.44 +/- 0.5 mg/kg. Nausea/vomiting and pruritus, related to the morphine infusion occurred in 45 patients (13.3%) and 14 patients (4.1%), respectively. No patients had respiratory depression or required Pediatric Intensive Care Unit admission. A low frequency of adverse events and a mean postoperative VAS pain score of 5 or less demonstrate that a continuous postoperative morphine infusion is a safe and effective method of pain management in patients with IS following PSF and SSI.

Current evidence suggests that local anesthetic wound infiltration should be employed as part of multimodal postoperative pain management. There is scarce data concerning the benefits of this anesthetic modality in laparoscopic weight loss surgery. Therefore, we analyzed the influence of trocar site infiltration with bupivacaine on the management of postoperative pain in laparoscopic bariatric surgery. This retrospective randomized study included 47 patients undergoing primary obesity surgery between January and September 2014. Laparoscopic gastric bypass was performed in 39 cases and sleeve gastrectomy in 8 cases. Patients were stratified into two groups depending on whether preincisional infiltration with bupivacaine and epinephrine was performed (study group, 27 patients) or not (control group, 20 patients). Visual analogue scale (VAS), International Pain Outcomes questionnaire, and rescue medication records were reviewed to assess postoperative pain. VAS scores in the study group and sleeve gastrectomy group were lower than those in the control and gastric bypass groups in the first 4 h postoperatively without reaching statistical significance (p > 0.05). VAS scores did not differ in any other period of time. No statistically significant differences in pain perception were registered according to the patient's pain outcomes questionnaire or the need for rescue medication. The present study did not conclusively prove the efficacy of bupivacaine infiltration by any of the three evaluation methods analyzed. Nevertheless, preincisional infiltration provides good level of comfort in the immediate postoperative period when analgesia is most urgent.

An Incidental Finding of a Talonavicular and Talocalcaneal Joint Coalition After a Tibial Pilon Fracture: A Case Report.

PubMed

Godoy, Heidi M; Micciche, Mark J

It has been proposed that patients with talocalcaneal and talonavicular coalitions have decreased ankle joint range of motion. It has also been reported that rotational forces regularly absorbed by the talocalcaneal joint are transferred to the ankle joint in patients with coalitions, increasing the stress on the ankle joint after trauma. To the best of our knowledge, only 1 reported study has detailed the increased stress placed on the ankle joint secondary to a coalition. We present a case study of a 53-year-old female who experienced a traumatic fall and subsequent right ankle fracture. Advanced imaging studies revealed a comminuted tibial pilon fracture and talocalcaneal and talonavicular joint coalitions. She underwent open reduction and internal fixation for treatment of the fracture, and the coalitions were not treated because they were asymptomatic. She was kept non-weightbearing for 6 weeks postoperatively and was returned to a regular sneaker at 10 weeks postoperatively. The postoperative films revealed stable intact fixation and pain-free gait with no increased restriction in her ankle joint range of motion. The hardware was removed at 13 months postoperatively. She had not experienced increased pain or arthritic changes at 15 months postoperatively. Copyright © 2017 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

2000-01-01

Twenty-one otherwise healthy dogs that presented for surgical repair of a ruptured cranial cruciate ligament were blindly and randomly given either carprofen (2.2 mg/kg body weight, orally) or a placebo beginning 12 hours preoperatively and continuing every 12 hours for a total of three doses. The patients were assessed for postoperative pain using a subjective pain score and given oxymorphone (0.1 mg/kg body weight, intramuscularly) every four hours if the pain score was 2 or greater. Blood samples were also collected to determine serum cortisol levels. There was a significant increase in serum cortisol levels in the immediate postoperative period in both the placebo group and the carprofen group (p less than 0.05). There was no significant difference in the percentage of increase in serum cortisol levels between the two groups. No correlation was evident between the serum cortisol levels and the corresponding pain scores in either group. This subjective method of assessing postoperative pain was not accurate and should not be relied upon for determination of postoperative analgesic administration. Perioperative oral administration of carprofen did not appear to be effective in controlling postoperative pain in these patients.

Despite the availability of high-quality guidelines and advanced pain management techniques acute postoperative pain management is still far from being satisfactory. The QUIPS (Quality Improvement in Postoperative Pain Management) project aims to improve treatment quality by means of standardised data acquisition, analysis of quality and process indicators, and feedback and benchmarking. During a pilot phase funded by the German Ministry of Health (BMG), a total of 12,389 data sets were collected from six participating hospitals. Outcome improved in four of the six hospitals. Process indicators, such as routine pain documentation, were only poorly correlated with outcomes. To date, more than 130 German hospitals use QUIPS as a routine quality management tool. An EC-funded parallel project disseminates the concept internationally. QUIPS demonstrates that patient-reported outcomes in postoperative pain management can be benchmarked in routine clinical practice. Quality improvement initiatives should use outcome instead of structural and process parameters. The concept is transferable to other fields of medicine. Copyright © 2011.

In the patients receiving morphine preoperatively, it is preoperatively important to avoid withdrawal symptoms postoperatively and to suppress postoperative pain and to maintain an appropriate anesthetic depth during the operation. We experienced six patients who had been under preoperative pain control with oral and/or epidural morphine and undergone palliative operation for their cancer pain. Four of the patients were preoperatively administered with oral morphine ranging from 30 to 270 mg.day-1. One patient was given epidural morphine 10 mg.day-1. Another was with morphine 1800 mg.day-1 orally and 50 mg.day-1 epiduraly. In all cases, general anesthesia was maintained with inhalation anesthetics. Anesthetic supplementation and postoperative pain management were performed with continuous i.v. infusion of morphine (half dosage of daily oral dosage), or subcutaneous injection (one sixth dosage of daily oral morphine) while preoperative epidural morphine was continued throughout the perioperative period. We were able to manage these patients well and none of them developed withdrawal symptom or increased postoperative pain.

To determine what effect the timing of carprofen administration has on the severity of postoperative pain in dogs undergoing ovariohysterectomy and to investigate the pharmacokinetics of carprofen under these conditions. A prospective, randomized, double-blind, clinical trial. Sixty-two adult bitches weighing between 10 and 25 kgs, undergoing elective ovariohysterectomy. Examinations were performed for 20 hours postoperatively using subjective visual assessment scoring systems (DIVAS) and objective mechanical nociceptive threshold measurements. Forty dogs were assigned to one of three groups: (1) preoperative carprofen; (2) postoperative carprofen; and (3) no analgesics (saline injections). The dose of carprofen was 4.0 mg/kg subcutaneously. In another 22 bitches, the pharmacokinetics of carprofen given preoperatively or postoperatively at the same dose were examined. The dogs given carprofen preoperatively had lower pain scores than the other groups, significantly so at 2 hours postextubation (P < .01 and P < .05, Kruskal-Wallis and post hoc Dunn's). Mechanical pain thresholds measured at the distal tibia showed the development of hyperalgesia at 12 and 20 hours postextubation; this was prevented by both the preoperative (P < .05 at 12 and 20 hours, Kruskal-Wallis) and postoperative (P < .05 at 20 hours, Kruskal-Wallis) administration of carprofen. Mechanical pain threshold testing at the wound showed a significant analgesic effect of carprofen. Plasma concentrations of carprofen were not directly related to analgesia; maximum plasma concentration, the area under the curve to the last data point, and area under the first moment curve up to the last data point were all significantly higher in the dogs given carprofen postoperatively (P < .05, Mann-Whitney). Preoperative administration of carprofen has a greater analgesic effect than postoperative administration in the early postoperative period in dogs undergoing ovariohysterectomy. Plasma levels of carprofen are not related to the degree of analgesia achieved. Carprofen provides effective analgesia after canine ovariohysterectomy. The timing of analgesic administration is important to optimize the control of postoperative pain.

Rectus sheath block (RSB) is used for postoperative pain relief in patients undergoing abdominal surgery with midline incision. Preoperative RSB has been shown to be effective, but it has not been compared with postoperative RSB. The aim of the present study is to evaluate postoperative pain, sleep quality and changes in the cytokine levels of patients undergoing gynaecological surgery with RSB performed preoperatively versus postoperatively. This study is a prospective, randomised, controlled (randomised, parallel group, concealed allocation), single-blinded trial. All patients undergoing transabdominal gynaecological surgery will be randomised 1:1 to the treatment intervention with general anaesthesia as an adjunct to preoperative or postoperative RSB. The objective of the trial is to evaluate postoperative pain, sleep quality and changes in the cytokine levels of patients undergoing gynaecological surgery with RSB performed preoperatively (n = 32) versus postoperatively (n = 32). All of the patients, irrespective of group allocation, will receive patient-controlled intravenous analgesia (PCIA) with oxycodone. The primary objective is to compare the interval between leaving the post-anaesthesia care unit and receiving the first PCIA bolus injection on the first postoperative night between patients who receive preoperative versus postoperative RSB. The secondary objectives will be to compare (1) cumulative oxycodone consumption at 24 hours after surgery; (2) postoperative sleep quality, as measured using a BIS-Vista monitor during the first night after surgery; and (3) cytokine levels (interleukin-1, interleukin-6, tumour necrosis factor-α and interferon-γ) during surgery and at 24 and 48 hours postoperatively. Clinical experience has suggested that RSB is a very effective postoperative analgesic technique, and we will answer the following questions with this trial. Do preoperative block and postoperative block have the same duration of analgesic effects? Can postoperative block extend the analgesic time? The results of this study could have actual clinical applications that could help to reduce postoperative pain and shorten hospital stays. Current Controlled Trials NCT02477098 15 June 2015.

The goal of this study was to determine if there were differences in outcomes of arthroscopic surgery in patients with inflammatory/degenerative temporomandibular joint (TMJ) disease who underwent early surgical intervention versus late surgical intervention. The study population included 44 consecutive patients who met the criteria for TMJ operative arthroscopy who were divided into early and late intervention groups. The time between the onset of symptoms and the performance of arthroscopy was used to determine entry into the early versus late intervention group. All groups were evaluated for changes in preoperative versus postoperative pain levels based on visual analog scale (VAS) scores and maximum interincisal opening distance. Statistical analyses included the Student t test to determine if there were significant differences between preoperative and postoperative assessments in the early and late intervention groups. The mean time between onset of symptoms in the early intervention group (21 patients) was 5.4 months compared with 33 months in the late intervention group (23 patients). All patient groups had statistically significant decreases in pain and improvement in maximum interincisal opening distance after arthroscopy. The early intervention group had a mean decrease in VAS pain scores of 5.14 compared with the late intervention group with a mean decrease in VAS pain scores of 2.84, and this difference was significant (P = .012). The early intervention group had a mean increase in maximum interincisal opening of 12.38 mm compared with the late intervention group with a mean increase of 7.70. Although statistical significance was not achieved for increases in maximum interincisal opening between the early and late intervention groups (P = .089), the difference between the 2 groups was suggestive of a trend. There were no surgical complications for either group; however, 2 patients in the late intervention group developed persistent chronic neuropathic pain, requiring pain management. TMJ arthroscopy reliably decreased pain and increased the maximum interincisal opening distance in the early and late intervention groups. The early intervention group had better surgical outcomes than the late intervention group. Arthroscopic surgery should be considered early in the management of patients with inflammatory/degenerative TMJ disease. Copyright © 2010 American Association of Oral and Maxillofacial Surgeons.

One of the currently used surgical techniques in isolated type II SLAP lesions is arthroscopic SLAP repair. Postoperatively, patients tend to suffer from a prolonged period of pain and are restricted in their sports activities for at least 6 months. The aim of this study was to prospectively evaluate the clinical outcome as well as the postoperative course of pain after arthroscopic type II SLAP repair. Outcome measures were assessed using the Individual Relative Constant Score (CS indiv ), the American Shoulder and Elbow Surgeons (ASES) Score, the Visual Analogue Scale (VAS), and the Short Form 36 (SF-36). Data were collected preoperatively, as well as at 3, 6, 12 and >24 months postoperatively. Eleven patients with an average age of 31.8 years (range: 22.8-49.8 years) underwent arthroscopic repair of isolated type II SLAP lesions. Mean follow-up time was 41.9 months (range: 36.1-48.4 months). 6 months after surgery, there was a statistically significant improvement of function according to the CS indiv (p = 0.004), the ASES Score (p = 0.006), and the SF-36 subscale "physical functioning" (p = 0.014) and a statistically significant decrease of pain according to the VAS (p = 0.007) and the SF-36 subscale "bodily pain" (p = 0.022) compared to preoperative levels. Arthroscopic repair of isolated type II SLAP lesions with suture anchors leads to a satisfactory functional outcome and return to pre-injury sports levels, with delayed, but significant pain relief observed 6 months after surgery. Thus, a return to sports should not be allowed earlier than 6 months after surgery, when patients have reached pain-free function and recovered strength. Researchregistry1761 (UIN).

Arthroscopic lysis and lavage surgery (AS) is an effective modality that can decrease pain and increase maximum interincisal opening (MIO) in patients with internal derangement (ID) of the temporomandibular joint (TMJ). However, some patients remain in pain or have limited mandibular range of motion despite AS. The purpose of this study was to determine the effectiveness, prevalence of adverse effects, and predictors of response to TMJ AS in patients with TMJ arthralgia and ID. A retrospective cohort study was conducted using data of patients who had undergone AS by a single surgeon (D.A.K.) from September 2010 to April 2015 in the Department of Oral and Maxillofacial Surgery at Massachusetts General Hospital (Boston, MA). Variables, including demographic data, medical history, and clinical presentation, were extracted and analyzed. Criteria for surgical success were defined as a postoperative MIO of at least 35 mm and a postoperative pain level no higher than 3 on an 11-point Likert-type numeric verbal pain rating scale. Appropriate descriptive and analytic statistics were computed and significance was set at a P value less than .05. Of the 247 participants, 226 (91.5%) were women. The mean age of the sample was 38 ± 15.4 years. Successful surgical outcome was achieved in 62.3% of patients. Based on logistic regression analysis, higher initial mean pain score and concurrent use of benzodiazepines were the only variables that predicted an unsuccessful surgical outcome (P < .001; P = .005). Adverse effects were reported by 13.4% of patients, the most common being postoperative increase in pain (13.4%), temporary malocclusion (1.2%), and temporary paresthesia in the preauricular region (0.4%). The results from this study indicate that in patients with ID of the TMJ unresponsive to noninvasive treatments, high initial pain scores and concurrent use of benzodiazepines are correlated with an unsuccessful outcome after AS.

Communication with orthopedic trauma patients is traditionally problematic with low response rates (RRs). The purpose of this investigation was to (1) evaluate the feasibility of communicating with orthopedic trauma patients postoperatively, utilizing an automated mobile phone messaging platform; and (2) assess the first 2 weeks of postoperative patient-reported pain and opioid use after lower extremity orthopedic trauma procedures. This was a prospective investigation at a Level 1 trauma center in the United States. Adult patients who were capable of mobile phone messaging and were undergoing common, lower extremity orthopedic trauma procedures were enrolled in the study. Patients received a daily mobile phone message protocol inquiring about their current pain level and amount of opioid medication they had taken in the past 24 h starting on postoperative day (POD) 3 and continuing through POD 17. Our analysis considered (1) Patient completion rate of mobile phone questions, (2) Patient-reported pain level (0-10 scale), and (3) Number and percentage of daily prescribed opioid medication patients reported taking. Twenty-five patients were enrolled in this investigation. Patients responded to 87.5% of the pain and opioid medication inquiries they received over the 2-week study period. There were no differences in RRs by patient age, sex, or educational attainment. Patient-reported pain decreased over the initial 2-week study period from an average of 4.9 ± 1.7 on POD 3 to 3 ± 2.2 on POD 16-17. Patients took an average of 68% of their maximum daily narcotic prescription on POD 3 compared with 35% of their prescribed pain medication on POD 16-17. We found that in orthopedic trauma patients, an automated mobile phone messaging platform elicited a high patient RR that improved upon prior methods in the literature. This method may be used to reliably obtain pain and medication utilization data after trauma procedures.

Postoperative effect of music listening has not been established in pediatric age. Response on postoperative distress and pain in pediatric day care surgery has been evaluated. Forty-two children were enrolled. Patients were randomly assigned to the music-group (music intervention during awakening period) or the non-music group (standard postoperative care). Slow and fast classical music and pauses were recorded and played via ambient speakers. Heart rate, blood pressure, oxygen saturation, glucose and cortisol levels, faces pain scale and Face, Legs, Activity, Cry, Consolability (FLACC) Pain Scale were considered as indicators of response to stress and pain experience. Music during awakening induced lower increase of systolic and diastolic blood pressure levels. The non-music group showed progressive increasing values of glycemia; in music-group the curve of glycemia presented a plateau pattern (P<0.001). Positive impact on reactions to pain was noted using the FLACC scale. Music improves cardiovascular parameters, stress-induced hyperglycemia. Amelioration on pain perception is more evident in older children. Positive effects seems to be achieved by the alternation of fast, slow rhythms and pauses even in pediatric age.

Numeric rating scale: patients' perceptions of its use in postoperative pain assessments.

The purpose of this study was to describe how patients perceive the use of the numeric rating scale in postoperative pain assessments. There are recommendations to use a pain scale to follow patients' postoperative pain. Most patients prefer the NRS but there is a discrepancy between patients and healthcare professionals how to interpret the ratings from the pain assessments. A descriptive design with a phenomenographic approach was used. Semi structured interviews were held with 25 patients. Three description categories emerged that illustrate patients' perceptions; use of the NRS facilitated communication of pain, it put demands on healthcare professionals and care routines and it contained interpretation difficulties. The NRS has a place in pain management according to the patients but there is a need for a dialogue to give the patients the opportunity to describe their pain and set a common goal.

The most painful activities during the days following cardiac surgery are coughing and deep breathing exercises. Cold therapy is an effective nonpharmacological method that decreases the pain during coughing and mobilization. In this study, the effects of cold therapy on pain and breathing exercises among patients with median sternotomy following cardiac surgery were investigated in a randomized crossover clinical trial. Data were collected from patients with median sternotomy (N = 34) in the first two postoperative days. Because of the crossover design of the study, each patient was taken as a simultaneous control. Gel pack application was used as the cold therapy. Patients underwent four episodes of deep breathing and coughing exercises using an incentive spirometer (volumetric). Patients were evaluated according to the visual analogue scale for pain intensity before and after deep breathing and coughing exercise sessions. The pain score was 3.44 ± 2.45 at baseline for deep breathing and coughing exercises on the first day. The reported postoperative pain in the gel-pack group was not significantly different before and after the deep breathing and coughing exercises, but it significantly increased in the no-gel-pack group (p < .001). Although the interaction between the treatment and time was significant (partial eta-squared: .09), the gel-pack group had a lower change in average pain levels. This interaction was not significant in terms of spirometric values. In conclusion, cold therapy had a positive effect on pain management in the early period of post-cardiac surgery but was not effective for the pain associated with breathing exercises.

Results of an interprofessional formulary initiative to decrease postoperative prescribing of i.v. acetaminophen are reported. After a medical center added i.v. acetaminophen to its formulary, increased prescribing of the i.v. formulation and a 3-fold price increase resulted in monthly spending of more than $40,000, prompting an organizationwide effort to curtail that cost while maintaining effective pain management. The surgery, anesthesia, and pharmacy departments applied the Institute for Healthcare Improvement's Model for Improvement to implement (1) pharmacist-led enforcement of prescribing restrictions, (2) retrospective evaluation of i.v. acetaminophen's impact on rates of opioid-related adverse effects, (3) restriction of prescribing of the drug to 1 postoperative dose on select patient care services, and (4) guideline-driven pain management according to an enhanced recovery after surgery (ERAS) protocol. Monitored metrics included the monthly i.v. acetaminophen prescribing rate, the proportion of i.v. acetaminophen orders requiring pharmacist intervention to enforce prescribing restrictions, and prescribing rates for select adjunctive analgesics. Within a year of project implementation, the mean monthly i.v. acetaminophen prescribing rate decreased by 83% from baseline to about 6 doses per 100 patient-days, with a decline in the monthly drug cost to about $4,000. Documented pharmacist interventions increased 2.7-fold, and use of oral acetaminophen, ketorolac, and gabapentin in ERAS areas increased by 18% overall. An interprofessional initiative at a large medical center reduced postoperative use of i.v. acetaminophen by more than 80% and yielded over $400,000 in annual cost savings.

The purpose of this prospective, randomized, double-blind study was to compare postoperative pain of root canal treatment in patients with asymptomatic mandibular molar teeth with necrotic pulp and periapical lesion using three different instrumentation techniques: hand, multi-file rotary (ProTaper Universal), and reciprocating single-file (Wave-One) instrumentation techniques. Ninety-six patients who fulfilled specific inclusion criteria were assigned to three groups according to the root canal instrumentation technique used: Hand (G1), ProTaper Universal (G2), and Wave-One (G3). One-visit root canal treatment was carried out, and the severity of the postoperative pain was assessed by the Heft-Parker visual analogue scale 6, 12, 18, 24, 48, and 72 h after treatment. Data were analyzed by Kruskal-Wallis, χ 2 , Cochrane Q, one-way ANOVA, and Spearman's correlation analyses (α = 0.05). The patients in group 3 reported significantly lower postoperative pain levels at 6, 12, and 18 h compared with the patients in the two other groups (P < .05). In addition, the patients in group 2 reported significantly lower postoperative pain levels at 6 and 12 h compared with the patients in group 1 (P < .05). There were no significant differences in postoperative pain between the three groups at other time intervals (P > .05). The analgesic consumption was significantly higher in group 1 (P < .05), but no difference was seen between the two other groups (P > .05). Postoperative pain was significantly lower in patients undergoing root canal instrumentation with the Wave-One file compared with the ProTaper Universal and hand files.

This randomized, double-blind, double-dummy, multicenter trial compared efficacy and safety of tramadol HCL 37.5 mg/paracetamol 325 mg combination tablet with tramadol HCL 50 mg capsule in the treatment of postoperative pain following ambulatory hand surgery with iv regional anesthesia. Patients received trial medication at admission, immediately after surgery, and every 6 hours after discharge until midnight of the first postoperative day. Analgesic efficacy was assessed by patients (n = 128 in each group, full analysis set) and recorded in a diary on the evening of surgery day and of the first postoperative day. They also documented the occurrence of adverse events. By the end of the first postoperative day, the proportion of treatment responders based on treatment satisfaction (primary efficacy variable) was comparable between the groups (78.1% combination, 71.9% tramadol; P = 0.24) and mean pain intensity (rated on a numerical scale from 0 = no pain to 10 = worst imaginable pain) had been reduced to 1.7 ± 2.0 for both groups. Under both treatments, twice as many patients experienced no pain (score = 0) on the first postoperative day compared to the day of surgery (35.9% vs 16.4% for tramadol/paracetamol and 36.7% vs 18% for tramadol treatment). Rescue medication leading to withdrawal (diclofenac 50 mg) was required by 17.2% patients with tramadol/paracetamol and 13.3% with tramadol. Adverse events (mainly nausea, dizziness, somnolence, vomiting, and increased sweating) occurred less frequently in patients under combination treatment (P = 0.004). Tramadol/paracetamol combination tablets provided comparable analgesic efficacy with a better safety profile to tramadol capsules in patients experiencing postoperative pain following ambulatory hand surgery.

To compare 2 irrigation solutions in terms of postoperative pain after single-visit treatment of chronic apical periodontitis with pulp necrosis. A total of 126 patients requiring treatment of apical periodontitis and pulp necrosis were randomly assigned to 2 groups according to the solution used for irrigation: 5.25% sodium hypochlorite (NaOCl) or 2% chlorhexidine gel (CLX) (63 patients in each group). To assess postoperative pain, a questionnaire and pain intensity scale were administered at 24, 48 and 72 hours and 7 days after the procedure. The χ2 test was used to compare the intensity of pain with the 2 irrigation solutions. No patients reported severe pain at any stage. Moderate pain was reported by 3% of patients (2/63 in each group) after 24 hours and by no patients beyond 24 hours, regardless of the irrigant used. Mild pain was more frequent but diminished rapidly (reported by 19% [12/63] of patients in the NaOCl group and 16% [10/63] in the CLX group at 24 hours, by 10% [6/63] in the NaOCl group and 11% [7/63] in the CLX group at 48 hours, by 3% [2/63] in both groups at 72 hours and by 2% [1/63] in both groups at 7 days). There were no statistically significant differences in postoperative pain between the 2 groups at any time point (p > 0.05). The incidence of postoperative pain after single-visit endodontic treatment of chronic apical periodontitis with pulp necrosis was uniformly low, regardless of the irrigant used.

The clinical course of patients with sciatica is believed to be favourable, but there is conflicting evidence on the postoperative course of this condition. We aimed to investigate the clinical course of sciatica following surgery. An electronic search was conducted on MEDLINE, EMBASE and CINAHL from inception to April 2015. We screened for prospective cohort studies investigating pain or disability outcomes for patients with sciatica treated surgically. Fractional polynomial regression analysis was used to generate pooled means and 95% confidence intervals (CI) of pain and disability up to 5 years after surgery. Estimates of pain and disability (converted to a 0-100 scale) were plotted over time, from inception to last available follow-up time. Forty records (39 cohort studies) were included with a total of 13,883 patients with sciatica. Before surgery, the pooled mean leg pain score was 75.2 (95% CI 68.1-82.4) which reduced to 15.3 (95% CI 8.5-22.1) at 3 months. Patients were never fully recovered in the long-term and pain increased to 21.0 (95% CI 12.5-29.5) at 5 years. The pooled mean disability score before surgery was 55.1 (95% CI 52.3-58.0) and this decreased to 15.5 (95% CI 13.3-17.6) at 3 months, and further reduced to 13.1 (95% CI 10.6-15.5) at 5 years. Although surgery is followed by a rapid decrease in pain and disability by 3 months, patients still experience mild to moderate pain and disability 5 years after surgery. WHAT DOES THIS REVIEW ADD?: This review provides a quantitative summary of the postoperative course of patients with sciatica. Patients with sciatica experienced a rapid reduction in pain and disability in the first 3 months, but still had mild to moderate symptoms 5 years after surgery. Although no significant differences were found, microdiscectomy showed larger improvements compared to other surgical techniques. © 2016 European Pain Federation - EFIC®.

Laryngeal microsurgery is performed to assess disorders of the larynx. Parecoxib is the only parenterally administered selective cyclooxygenase (COX)-2 inhibitor widely used in acute pain control. The purpose of this study is to assess the analgesic effects of parecoxib compared with morphine for postoperative sore throat in patients undergoing laryngeal microsurgery. Fifty patients were randomly allocated to receive either parecoxib 0.5 mg/kg or morphine 50 μg/kg prior to anesthesia induction. General anesthesia was maintained with sevoflurane 2-4%. Postoperative sore throat and other outcomes were measured at a postanesthesia care unit (PACU) 4 hours and 24 hours postoperatively. The severity of postoperative sore throat was assessed by sore throat score as follows: none (0) = no pharyngeal or laryngeal discomfort; mild (1) = no pain at rest, but swallowing induced mild pain or discomfort; moderate (2) = constant pain without swallowing exacerbation; and severe (3) = constant pain with swallowing or respiratory exacerbation. The incidences of postoperative side effects (nausea, vomiting, itching, dizziness, and somnolence) were also recorded. Demographic data from the parecoxib (n = 25) and morphine (n = 25) groups did not differ significantly. The parecoxib group depicted similar sore throat scores as the morphine group at three measured postoperative time points. Patients requiring postoperative analgesics were comparable between the parecoxib group and morphine group (2/25, 8% vs. 3/25, 12%, p = 0.64). Overall postoperative adverse events were fewer in the parecoxib group than the morphine group (3/25, 12% vs. 9/25, 36%, p = 0.047). Both parecoxib and morphine are effective to attenuate postoperative sore throat after laryngeal microsurgery. Parecoxib may be an effective and well-tolerated injectable analgesic to manage postoperative sore throat after laryngeal microsurgery. Copyright © 2014. Published by Elsevier Taiwan.

We investigated the effect of remifentanil vs fentanyl on stress response and postoperative pain in people with special needs undergoing day-case dental surgery. Forty-six adult patients with cognitive impairment undergoing day-case dental surgery under general anesthesia were allocated to receive intraoperatively either fentanyl 50 μg iv bolus (group F, n = 23) or continuous infusion of remifentanil 0.5-1 μg/kg/min (group R, n = 23). Iintraoperative hemodynamic parameters were recorded and serum inflammatory mediators [tumor necrosis factor-α, substance-P], stress hormons (melatonin, cortisol) and β-endorphin were measured. Postoperative pain was assessed during the first postoperative 12 hours with the Wong-Baker faces pain-rating scale. Demographics were similar in two groups. The two groups did not differ regarding their effects on inflammatory mediators, stress hormons and postoperative pain scores. However, the use of remifentanil prevented intraoperative increases of arterial blood pressure and heart rate. Remifentanil and fentanyl did not affect differently stress and inflammatory hormones during day-case dental surgery, although remifentanil may render intraoperative management of hemodynamic responses easier. Both opioids are equally efficient for postoperative pain management following dental surgery in people with special needs.

Evidence has suggested that males and females experience and report feeling pain differently. The aim of this study was to determine the postoperative perception levels of both females and males after neodymium-doped yttrium aluminum garnet (Nd:YAG) laser frenectomy and conventional frenectomy, and to compare the perceptions between genders. Eighty-nine patients requiring frenectomy were randomly assigned to have treatment with either the conventional frenectomy or with the Nd:YAG laser. Postoperative discomfort (pain, chewing, talking) was recorded using a visual analog scale (VAS) on the operation day and postoperative days 1, 3, 7 and 10. According to the female VAS scores of the pain, chewing and speaking discomfort were statistically higher in the conventional group than those of the laser group on the operation day, and on the first and third postoperative days. Pain discomfort in males was statistically higher in the conventional group than those of the laser group on the operation day. Speaking discomfort in males was statistically higher in the conventional group than those of the laser group on the operation day and the first postoperative day. The present study indicated that Nd:YAG laser treatment used for frenectomies provides better postoperative comfort for each gender, especially in females in terms of pain, chewing and speaking than the conventional procedure up to the seventh postoperative day. According to our results, Nd:YAG laser may provide a safe, bloodless, painless surgery and an impressive alternative for frenectomy operations. © 2015 Australian Dental Association.

Postoperative pain control is essential for optimal patient outcomes. Ketorolac is an attractive alternative for achieving pain control postoperatively, but concerns over postoperative bleeding have limited its use. Computer searches of the MEDLINE, EMBASE, and Cochrane Library databases were performed. Twenty-seven double-blind, randomized, controlled studies were reviewed by two independent investigators for the incidence of adverse events, including postoperative bleeding. Comprehensive meta-analysis software was used to evaluate the differences between ketorolac and control groups. Twenty-seven studies with 2314 patients were analyzed. Postoperative bleeding occurred in 33 of 1304 patients (2.5 percent) in the ketorolac group compared with 21 of 1010 (2.1 percent) in the control group (OR, 1.1; 95 percent CI, 0.61 to 2.06; p = 0.72). Adverse events were similar in the groups, 31.7 percent in the control group and 27.9 percent in the ketorolac group (OR, 0.64; 95 percent CI, 0.41 to 1.01; p = 0.06). There was a lower incidence of adverse effects with low-dose ketorolac (OR, 0.49; 95 percent CI, 0.27 to 0.91; p = 0.02). Pain control with ketorolac was superior to controls and equivalent to opioids. This is the first meta-analysis of randomized controlled trials examining whether there is increased postoperative bleeding with ketorolac. Postoperative bleeding was not significantly increased with ketorolac compared with controls, and adverse effects were not statistically different between the groups. Pain control was found to be superior with ketorolac compared with controls. Ketorolac should be considered for postoperative pain control, especially to limit the use of opioid pain medications.

Sathorn, C; Parashos, P; Messer, H

2008-02-01

The aim of this systematic review was to assess the evidence regarding postoperative pain and flare-up of single- or multiple-visit root canal treatment. CENTRAL, MEDLINE and EMBASE databases were searched. Reference lists from identified articles were scanned. A forward search was undertaken on the authors of the identified articles. Papers that had cited these articles were also identified through Science Citation Index to identify potentially relevant subsequent primary research. The included clinical studies compared the prevalence/severity of postoperative pain or flare-up in single- and multiple-visit root canal treatment. Data in those studies were extracted independently. Sixteen studies fitted the inclusion criteria in the review, with sample size varying from 60 to 1012 cases. The prevalence of postoperative pain ranged from 3% to 58%. The heterogeneity amongst included studies was far too great to conduct meta-analysis and yield meaningful results. Compelling evidence indicating a significantly different prevalence of postoperative pain/flare-up of either single- or multiple-visit root canal treatment is lacking.

Use of postoperative steroids to reduce pain and inflammation.

PubMed

Fleischli, J W; Adams, W R

1999-01-01

Postoperative injection of a steroid is used by many podiatric surgeons to reduce pain and inflammation after foot surgery. The authors present a review of the literature on postoperative steroid use from many medical specialties as well as a review of wound and bone healing. The literature indicates that using a steroid is a safe and effective means to reduce postoperative pain and edema. Studies have shown steroids to delay healing, inhibit collagen synthesis, and increase the risk of postoperative infection. No author reported a delay in wound or bone healing or increased infection rate in patients in which a steroid was used. Although there is literature to support this practice, many questions remain and further investigation is needed.

Recent evidence points to an association between experimental pain measures obtained preoperatively and acute postoperative pain (POP). We hypothesized that pain temporal summation (TS) might be an additional predictor for POP insofar as it represents the neuroplastic changes that occur in the central nervous system following surgery. Therefore, a wide range of psychophysical tests (TS to heat and mechanical repetitive stimuli, pain threshold, and suprathreshold pain estimation) and personality tests (pain catastrophizing and anxiety levels) were administered prior to thoracotomy in 84 patients. POP ratings were evaluated on the 2nd and 5th days after surgery at rest (spontaneous pain) and in response to activity (provoked pain). Linear regression models revealed that among all assessed variables, enhanced TS and higher pain scores for mechanical stimulation were significantly associated with greater provoked POP intensity (overall r2 = 0.225, P = .008). Patients who did not demonstrate TS to both modalities reported lower scores of provoked POP as compared with patients who demonstrated TS in response to at least 1 modality (F = 4.59 P = .013). Despite the moderate association between pain catastrophizing and rest POP, none of the variables predicted the spontaneous POP intensity. These findings suggest that individual susceptibility toward a greater summation response may characterize patients who are potentially vulnerable to augmented POP. This study proposed the role of pain temporal summation assessed preoperatively as a significant psychophysical predictor for acute postoperative pain intensity. The individual profile of enhanced pain summation is associated with the greater likelihood of higher postoperative pain scores.

Local infiltration analgesia (LIA) has emerged as an alternative treatment for postoperative pain after total knee arthroplasty (TKA). Its efficacy remains inconclusive with inconsistent results from previous studies and meta-analyses. There is no agreement on which local anaesthetic agent and infiltration technique is most effective and well tolerated. The objective was to compare LIA after primary TKA with placebo or no infiltration in terms of early postoperative pain relief, mobilisation, length of hospital stay (LOS) and complications when used as a primary treatment or as an adjunct to regional anaesthesia. The role of injection sites, postoperative injection or infusion and multimodal drug injection with ketorolac were also explored. A systematic review and meta-analysis of randomised controlled trials (RCTs). A literature search was performed using PubMed and SCOPUS up to September 2015. RCTs comparing LIA with placebo or no infiltration after primary TKA in terms of pain score and opioid consumption at 24 and 48 h, mobilisation, LOS and complications were included. In total 38 RCTs were included. LIA groups had lower pain scores, opioid consumption and postoperative nausea and vomiting, higher range of motion at 24 h and shorter LOS than no injection or placebo. After subgroup analysis, intraoperative peri-articular but not intra-articular injection had lower pain score at 24 h than no injection or placebo with the pooled mean difference of pain score at rest of -0.89 [95% CI (-1.40 to -0.38); I = 92.0%]. Continuing with postoperative injection or infusion reduced 24-h pain score with the pooled mean difference at rest of -1.50 [95% CI (-1.92 to -1.08); I = 60.5%]. There was no additional benefit in terms of pain relief during activity, opioid consumption, range of movement or LOS when LIA was used as an adjunct to regional anaesthesia. Four out of 735 patients receiving LIA reported deep knee infection, three of whom had had postoperative catheter placement. LIA is effective for acute pain management after TKA. Intraoperative peri-articular but not intra-articular injection may be helpful in pain control up to 24 h. The use of postoperative intra-articular catheter placement is still inconclusive. The benefit of LIA as an adjunctive treatment to regional anaesthesia was not demonstrated.

Proper diagnosis and treatment of sacroiliac joint (SIJ) pain remains a clinical challenge. Dysfunction of the SIJ can produce pain in the lower back, buttocks, and extremities. Triangular titanium implants for minimally invasive surgical arthrodesis have been available for several years, with reputed high levels of success and patient satisfaction. This study reports on a novel hydroxyapatite-coated screw for surgical treatment of SIJ pain. Data were prospectively collected on 32 consecutive patients who underwent minimally invasive SIJ fusion with a novel hydroxyapatite-coated screw. Clinical assessments and radiographs were collected and evaluated at 3, 6, and 12 months postoperatively. Mean (standard deviation) patient age was 55.2 ± 10.7 years, and 62.5% were female. More patients (53.1%) underwent left versus right SIJ treatment, mean operative time was 42.6 ± 20.4 minutes, and estimated blood loss did not exceed 50 mL. Overnight hospital stay was required for 84% of patients, and the remaining patients needed a 2-day stay (16%). Mean preoperative visual analog scale back and leg pain scores decreased significantly by 12 months postoperatively (P < 0.01). Mechanical stability was achieved in 93.3% (28/30) of patients, and all patients who were employed preoperatively returned to work within 3 months. Two patients who required revision surgery reported symptom improvement within 3 weeks and did not require subsequent surgery. Positive clinical outcomes are reported 1 year postoperatively after implantation of a novel implant to treat sacroiliac joint pain. Future clinical studies with larger samples are warranted to assess long-term patient outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

Effect of painless diabetic neuropathy on pressure pain hypersensitivity (hyperalgesia) after acute foot trauma

PubMed Central

Wienemann, Tobias; Chantelau, Ernst A.; Koller, Armin

2014-01-01

Introduction and objective Acute injury transiently lowers local mechanical pain thresholds at a limb. To elucidate the impact of painless (diabetic) neuropathy on this post-traumatic hyperalgesia, pressure pain perception thresholds after a skeletal foot trauma were studied in consecutive persons without and with neuropathy (i.e. history of foot ulcer or Charcot arthropathy). Design and methods A case–control study was done on 25 unselected clinical routine patients with acute unilateral foot trauma (cases: elective bone surgery; controls: sprain, toe fracture). Cases were 12 patients (11 diabetic subjects) with severe painless neuropathy and chronic foot pathology. Controls were 13 non-neuropathic persons. Over 1 week after the trauma, cutaneous pressure pain perception threshold (CPPPT) and deep pressure pain perception threshold (DPPPT) were measured repeatedly, adjacent to the injury and at the opposite foot (pinprick stimulators, Algometer II®). Results In the control group, post-traumatic DPPPT (but not CPPPT) at the injured foot was reduced by about 15–25%. In the case group, pre- and post-operative CPPPT and DPPPT were supranormal. Although DPPPT fell post-operatively by about 15–20%, it remained always higher than the post-traumatic DPPPT in the control group: over musculus abductor hallucis 615 kPa (kilopascal) versus 422 kPa, and over metatarsophalangeal joint 518 kPa versus 375 kPa (medians; case vs. control group); CPPPT did not decrease post-operatively. Conclusion Physiological nociception and post-traumatic hyperalgesia to pressure are diminished at the foot with severe painless (diabetic) neuropathy. A degree of post-traumatic hypersensitivity required to ‘pull away’ from any one, even innocuous, mechanical impact in order to avoid additional damage is, therefore, lacking. PMID:25397867

To provide parents of children with accurate information regarding postoperative pain, its management, and functioning following common surgical procedures. The increasing prevalence of pediatric day-case procedures demands a more thorough understanding of the recovery profiles associated with these operations. To document postdischarge pain profiles, analgesia requirements, and functional limitation in children following tonsillectomy, orchidopexy, or inguinal hernia repair (IHR). Following hospital discharge, parents were asked to record their children's pain levels, analgesia consumption, and degree of functional limitation each day until complete recovery. Pain and functional limitation were measured using the Parents' Postoperative Pain Measurement (PPPM) scale and Functional Activity Score, respectively. Significant pain was defined as PPPM ≥ 6. One hundred and five patients (50, tonsillectomy; 24, orchidopexy; and 31, IHR) were recruited. Median PPPM was always <6 after IHR, ≥6 only on day 1 after orchidopexy and persisted through to day 8 after tonsillectomy. Mild or severe functional limitation was observed after all surgeries and persisted for 4, 5, and 4 days after median PPPM < 6 after IHR, orchidopexy, and tonsillectomy, respectively. Combination analgesia was commonly administered after orchidopexy and tonsillectomy but less so after IHR. The general practitioner consultation rate following tonsillectomy was 54%. After tonsillectomy, children experience significant pain and severe functional limitation for 7 days after surgery. For many children, pain and functional limitation persists throughout the second postoperative week. In children undergoing orchidopexy, paracetamol and ibuprofen provide adequate analgesia. Pain begins to subside after the first postoperative day, and normal activity resumes after 7 days. After IHR, children experience mild pain that can be treated with paracetamol and return to normal functioning after 4 days. © 2011 Blackwell Publishing Ltd.

Axial pain after posterior cervical spine surgery: a systematic review.

2011-02-01

Posterior operative approach has been the standard treatment for cervical compressive myelopathy, and axial pain after laminoplasty or laminectomy as a postoperative complication is now gradually receiving more and more attention. The objective of this study was to provide a systematic review of the current understanding of axial pain after cervical laminoplasty and laminectomy, and summarize clinical features, influence factors and preventive measures of axial pain after posterior decompressive surgery based on a review of literature published in the English language. Axial pain distributes over nuchal, periscapular and shoulder regions. Posterior surgery is not the major cause of axial pain, but axial pain can be worsened by the procedure. There are many clinical factors that influence postoperative axial pain such as age, preoperative axial pain, different surgical technique and postoperative management, but most of them are still controversial. Several surgical modifications have been innovated to reduce axial pain. Less invasive surgery, reconstruction of the extensor musculature, avoiding detachment of the semispinalis cervicis muscle and early removal of external immobilization have proved to be effective. Axial pain is under the influence of multiple factors, so comprehensive methods are required to reduce and avoid the postoperative axial pain. Because of methodological shortcomings in publications included in this systematic review, different results from different studies may be produced due to differences in study design, evaluation criteria, sample size, and incidence or severity of axial pain. More high-quality studies are necessary for drawing more reliable and convincing conclusions.

The administration of an equimolar mixture of nitrous oxide and oxygen (N2O) is recommended during painful procedures. However, the evaluation of its use during physiotherapy after surgery has not been reported, although pain may hamper physiotherapy efficiency. This study investigated whether the use of N2O improves the efficacy of post-operative physiotherapy after multilevel surgery in patients with cerebral palsy. It was a randomized 1:1, double-blind, placebo-controlled study. All patients had post-operative physiotherapy starting the day after surgery. Patients received either N2O or placebo gas during the rehabilitation sessions. All patients had post-operative pain management protocol, including pain medication as needed for acute pain. The primary objective was to reach angles of knee flexion of 110° combined with hip extension of 10°, with the patient lying prone, within six or less physiotherapy sessions. Secondary evaluation criteria were the number of sessions required to reach the targeted angles, the session-related pain intensity and the analgesics consumption for managing post-operative pain. Sixty-four patients were enrolled. Targeted angles were achieved more often in the N2O group (23 of 32, 72%, vs. Placebo: 13/ of 32, 41%; p = 0.01). The administration of N2O during post-operative physiotherapy can help to achieve more quickly an improved range of motion, and, although not significant in our study, to alleviate the need for pain medication. Further studies evaluating the administration of N2O in various settings are warranted. During this randomized placebo-controlled double-blind study, children receiving nitrous oxide and oxygen (N2O) achieved more often the targeted range of motion during physiotherapy sessions after multilevel surgery. Compared to placebo, nitrous oxide and oxygen (N2O) enabled a better management of acute pain related to physiotherapy procedures. © 2017 European Pain Federation - EFIC®.

From acute to chronic postsurgical pain: the significance of the acute pain response.

PubMed

Blichfeldt-Eckhardt, Morten Rune

2018-03-01

The thesis comprises an overview and four papers, all published or submitted for publication in international peer-reviewed scientific journals.
 
Chronic pain after surgery is a common and debilitating complication after many types of surgery. The cause and pathology behind is still mainly uncovered, though several risk factors have been proposed. One of the strongest risk factors for persistent postsurgical pain is the intensity of the acute pain response though the mechanisms involved remain unsettled. The acute pain response consists of several different types of pain (i.e. somatic pain, visceral pain, referred pain, neuropathic pain). It's uncovered whether some components of the acute pain response are closer correlated to chronic pain than others and whether treatment of acute pain can change the risk of developing chronic pain.
 The aim of the thesis was to investigate which components of the acute pain response, was correlated to chronic postsurgical pain in patients for cholecystectomy and lobectomy.
 Furthermore, to study the type and time course of ipsilateral shoulder pain after lobectomy and whether an ultrasound-guided supraclavicular phrenic nerve block was effective in preventing acute and chronic shoulder pain after major thoracic surgery.
 Paper I is based on a prospective, observational, multicenter, cohort study, in which 100 patients for cholecystectomy was examined preoperatively, 1 week postoperatively and 3, 6, and 12 months postoperatively for pain, psychological factors and signs of hypersensitivity.
 Paper II and III are based on a prospective, observational, cohort study, in which 60 patients for lobectomy ware examined preoperatively, 4 days postoperatively and 12 months postoperatively for pain, psychological factors and signs of hypersensitivity. 
Paper IV is based on a prospective, randomized, double-blind and placebo-controlled trial, where 76 patients were randomized to receive ultrasound guided supraclavicular phrenic nerve block with a blinded study solution (ropivacaine or saline). The primary endpoint was pain within the first 6 hours after surgery. Secondary endpoints included pain the following days and after 3 months.
 
Paper I: Nine patients developed chronic unexplained pain 12 months postoperatively. In a multivariate analysis, cumulated visceral pain during the first week and number of preoperative biliary pain attacks were identified as independent risk factors for unexplained pain 12 months after surgery. There were no consistent signs of increased hypersensitivity in the referred pain area before or after the operation in patients with chronic pain. 
Paper II: Sixteen patients developed chronic pain 12 months postoperatively. In a multivariate analysis thoracic pain during activity was the only significant predictor of chronic pain 12 months after surgery. Shoulder pain, referred pain and overall pain was not significant predictors. There were no signs of general hypersensitivity 12 months after surgery. 
Paper III: Forty-seven (78%) of patients experienced postoperative shoulder pain, but only 25 patients (42%) experienced clinically relevant pain (NRS > 3). On postoperative day 4, 19 (32%) of patients suffered shoulder pain, but only 4 (7%) suffered clinically relevant pain. Only 4 patients (8%) suffered chronic shoulder pain. Ipsilateral shoulder pain of the

 
musculoskeletal type is more intense than referred ipsilateral shoulder pain, though referred shoulder pain is more common. Surgical approach was not related to incidence of shoulder pain or type of pain.
 Paper IV: Shoulder pain within 6 hours of the operation was reported in 9 patients (24%) in the treatment group versus 26 (68%) in the placebo group (p<0.0001). Absolute and relative risk reductions were 44% (95% CI 22-67%) and 65% (95% CI 41-80%), respectively. No major complications, including respiratory compromise, were observed. Subsequent treatment with a nerve catheter was effective during the first 36 hours after surgery, but because of loss of nerve catheter or early submission of patients, data concerning pain the following days and after 3 months were inconclusive.

2016-01-01

Background. Because of economic reasons, day surgery rates have steadily increased in many countries and the trend is to perform around 70% of all surgical procedures as day surgery. Literature shows that postoperative pain treatment remains unfulfilled in several fields such as orthopedic and general surgery patients. In Italy, the day surgery program is not yet under governmental authority and is managed regionally by local practices. Aim. To investigate the trends in pain intensity and its relation to type of surgeries and pain therapy protocols, in postoperative patients, discharged from three different Ambulatory Surgeries located in North West Italy (Piedmont region). Method. The present study enrolled 276 patients who undergone different surgical procedures in ambulatory regimen. Patients recorded postoperative pain score twice a day, compliance with prescribed drugs, and pain related reasons for contacting the hospital. Monitoring lasted for 7 days. Results. At discharge, 72% of patients were under weak opioids, 12% interrupted the treatment due to side effects, 17% of patients required extra drugs, and 15% contacted the hospital reporting pain problems. About 50% of patients experienced moderate pain during the first day after surgery. Results from our study show that most of the patients experienced avoidable pain after discharge. PMID:28115878

Morphine consumption can vary widely between individuals even for identical surgical procedures. As mu-opioid receptor (OPRM1) is known to modulate pain perception and mediate the analgesic effects of opioid compounds in the central nervous system, we examined the influence of two OPRM polymorphisms on acute post-operative pain and morphine usage in women undergoing elective caesarean delivery. Data on self-reported pain scores and amount of total morphine use according to patient-controlled analgesia were collected from 994 women from the three main ethnic groups in Singapore. We found statistically significant association of the OPRM 118A>G with self-administered morphine during the first 24-hour postoperative period both in terms of total morphine (p = 1.7 x 10(-5)) and weight-adjusted morphine (p = 6.6 x 10(-5)). There was also significant association of this OPRM variant and time-averaged self-rated pain scores (p = 0.024). OPRM 118G homozygotes used more morphine and reported higher pain scores than 118A carriers. Other factors which influenced pain score and morphine usage include ethnicity, age and paying class. Our results suggest that ethnicity and OPRM 118A>G genotype are independent and significant contributors to variation in pain perception and postoperative morphine use in patients undergoing cesarean delivery.

Postoperative pain control after total knee arthroplasty (TKA) remains a great challenge. The management of pain in the immediate postoperative period is one of the most critical aspects to allow speedier rehabilitation and reduce the risk of postoperative complications. Recently, periarticular infiltration anesthesia has become popular, but the outcome is controversial. Some studies have shown transient effects, "rebound pain", or no effectiveness in pain control. Continuous intra-articular infusion technique has been introduced to improve these transient effects, but more clinical studies are needed. Furthermore, the potential risk of early periprosthetic joint infection is causing concerning. We plan to compare continuous intra-articular infusion anesthesia with epidural infusion anesthesia after TKA to assess the effectiveness of this technique in reducing pain, in improving postoperative function, and to look at the evidence for risk of early infection. This trial is a randomized, controlled study. Patients (n = 214) will be randomized into two groups: to receive continuous intra-articular infusion anesthesia (group C); and epidural infusion anesthesia (group E). For the first 3 postoperative days, pain at rest, active range of motion (A-ROM), rescue analgesia and side effects will be recorded. At 3-month and 6-month follow-up, A-ROM, C-reactive protein, erythrocyte sedimentation rate, and synovial fluid cell count and culture will be analyzed. The results from this study will provide clinical evidence on the efficacy of a continuous intra-articular infusion technique in reducing pain, postoperative functional improvement and safety. It will be the first randomized controlled trial to investigate infection risk with local anesthesia after TKA. ClinicalTrials.gov identifier: ChiCTR-TRC-13003999.

Background: We carried out a study to evaluate the effects of protective premedication with Acetaminophen, Gabapentin and combination of Acetaminophen with Gabapentin on post-operative analgesia in patients undergoing open cholecys-tectomy under general anesthesia. Patients & Methods: The study was conducted in a double-blind randomized and controlled manner in 120 consenting patients of either sex belonging to ASA physical status grade I and II, between the age groups of 20 to 50 years, weighing between 40 to 65 kg and undergoing elective surgery (open cholecystectomy) under general anesthesia. The patients were divided into 4 groups: 1: placebo, 2: Acetaminophen 1000 mg, 3: 1200 mg Gabapentin, 4: Acetaminphen 1000 mg plus 1200 mg Gabapentin. The drugs were given two hours before induction. Time, number and total amount of rescue analgesic (tramadol) and VAS score at rest and on movement. Side effects like any episode of nausea/vomiting and level of sedation were noted. Results: Premedication with antihyperalgesic and analgesic agents helps to decrease postoperative pain scores. Gabapentin premedication is effective for providing better postoperative pain relief with lower and delayed requirements of rescue analgesics, but causes more episodes of nausea and vomiting and higher levels of sedation.

The aim of this study was to evaluate the effectiveness of submucosal application of tramadol, for acute postoperative facial pain, following the extraction of impacted third molar teeth. This prospective, double-blind, randomised placebo-controlled study included 60 ASA I-II patients undergoing impacted third molar surgery under local anaesthesia. Following the surgical procedure, patients were randomly divided into two groups; group T (1 mg/kg tramadol) and group S (2-mL saline). Treatments were applied submucosally after surgery. Pain after extraction was evaluated using a visual analogue scale (VAS) 0.5, 1, 2, 4, 6, 12, 24, and 48 h postoperatively. The time at which the first analgesic drug was taken, the total analgesic dose used, and adverse tissue reactions were also evaluated. In group T, postoperative VAS scores were significantly lower compared to that in group S (p < 0.05). This study demonstrated that post-operative submucosal application of tramadol is an effective method for reducing acute post-operative facial pain after impacted third molar surgery.

Laparoscopy (LSC) offers superior patient outcomes compared to laparotomy. Small retrospective/prospective series have suggested robotics offers further reduction in postoperative pain and pain medication use compared to standard LSC. Our objective was to compare postoperative pain in patients undergoing robotically assisted (RBT) versus standard LSC for newly diagnosed endometrial cancer. All preoperative endometrial cancer cases scheduled for RBT and LSC from May 1, 2007 to June 9, 2010 were identified. For this analysis, we only included cases not requiring conversion to laparotomy. All patients were offered intravenous (IV) patient-controlled analgesia (PCA) postoperatively. Intraoperative equivalent fentanyl doses (IEFDs) and pain scores in the postanesthesia care unit (PACU) were assessed. IV PCA was used in 206 RBTs (86 %) and 208 LSCs (88 %). Median IEFD was 425 μg for LSCs and 500 μg for RBTs (P = 0.03). Median pain scores on PACU arrival were similar in both groups. Median highest pain score was 5 for LSCs and 4 for RBTs (P = 0.007). Linear regression demonstrated that the IEFD was not correlated with the highest pain score (R = 0.09; P = 0.07). Fentanyl was used postoperatively in 196 of 206 RBTs (95 %) and 187 of 208 LSCs (90 %). The total fentanyl doses were 242.5 (range 0-2705) μg and 380 (range 0-2625) μg, respectively (P < 0.001). The median hourly fentanyl doses were 16.7 (range 0-122.5) μg and 23.5 (range 0-132.4) μg, respectively (P = 0.005). Simultaneous multiple regression analysis further demonstrated RBT was independently associated with a lower total fentanyl dose compared to LSC (P = 0.02). RBT is independently associated with significantly lower postoperative pain and pain medication requirements compared to LSC. The amount of intraoperative fentanyl analgesia does not appear to correlate with postoperative pain.Endometrial cancer is the most common gynecologic malignancy in the United States, with an estimated 47,130 new cases in 2012.1 An estimated 287,100 women were diagnosed with endometrial cancer worldwide in 2008.2 Surgery is the primary treatment of choice for the majority of these women.3 The standard surgical approach has been total abdominal hysterectomy, bilateral salpingo-oophorectomy, and staging via laparotomy. Multiple retrospective series have shown that a less invasive surgical approach via laparoscopy (LSC) is feasible and safe, and also associated with improved perioperative outcomes compared to laparotomy in these patients.4 The Gynecologic Oncology Group (GOG) published results of the largest randomized trial (LAP2) comparing LSC to laparotomy in patients with newly diagnosed endometrial carcinoma in 2009.5,6 This landmark study essentially changed the accepted standard surgical approach in this group. Postoperative complications, median blood loss, and median length of stay (LOS), despite increased operative time, were significantly lower in LSC patients despite 25 % requiring conversion to laparotomy.5 The first 802 eligible patients randomized in LAP2 also participated in a quality-of-life (QOL) study. Within 6 weeks of surgery, patients assigned to LSC reported significantly better QOL on all scales other than fear of recurrence.6 Overall, during this 6-week postoperative period, patients assigned to LSC had superior QOL, fewer physical symptoms, less pain and pain-related interference with functioning, better physical functioning and emotional state, earlier resumption of normal activities, earlier return to work, and better body image compared to those assigned to laparotomy.6 Recurrence-free and overall survivals were the same in both groups.7 Multiple published retrospective series have shown possible benefits, such as reduced postoperative pain, using the robotic (RBT) platform compared to LSC or laparotomy in patients with endometrial cancer.8-11 In a randomized trial, LSC was found to be associated with less postoperative pain compared to vaginal approaches in patients undergoing hysterectomy for benign gynecologic disease.12 A small retrospective series reported further reductions in postoperative pain in patients who had undergone an RBT hysterectomy compared to a standard total LSC hysterectomy for benign indications.13 A recent cost analysis suggested that patients experienced less pain and required less pain medication use after RBT procedures compared to LSC for endometrial cancer.14 Based on these reports, we sought to analyze postoperative pain and the use of pain medication in patients undergoing RBT compared to standard transperitoneal LSC procedures for newly diagnosed endometrial cancer during a concurrent time period. Of note, current RBT surgery is not truly robotic in that it is not autonomous. A more appropriate term is “computer-assisted surgery,” but to satisfy current convention, we refer to it as “robotic surgery” in this manuscript.

Patient-reported outcomes (PRO) represent an important measure of cancer therapy effect. For patients with metastatic epidural spinal cord compression (MESCC), hybrid therapy using separation surgery and stereotactic radiosurgery preserves neurologic function and provides tumor control. There is currently a paucity of data reporting PRO after such combined modality therapy for MESCC. Delineation of hybrid surgery-radiosurgery therapy effect on PRO validates the hybrid approach as an effective therapy resulting in meaningful symptom relief. Brief Pain Inventory (BPI) and MD Anderson Symptom Inventory-Spine Tumor (MDASI-SP), PROs validated in the cancer population, were prospectively collected. Patients with MESCC who underwent separation surgery followed by stereotactic radiosurgery were included. Separation surgery included a posterolateral approach without extensive cytoreductive tumor excision. A median postoperative radiosurgery dose of 2700 cGy was delivered. The change in PRO 3 months after the hybrid therapy represented the primary study outcome. Preoperative and postoperative evaluations were analyzed using the Wilcoxon signed-rank test for matched pairs. One hundred eleven patients were included. Hybrid therapy resulted in a significant reduction in the BPI items "worst" and "right now" pain ( P < .0001), and in all BPI constructs (severity, interference with daily activities, and pain experience, P < .001). The MDASI-SP demonstrated reduction in spine-specific pain severity and interference with general activity ( P < .001), along with decreased symptom interference ( P < .001). Validated PRO instruments showed that in patients with MESCC, hybrid therapy with separation surgery and radiosurgery results in a significant decrease in pain severity and symptom interference. These prospective data confirm the benefit of hybrid therapy for treatment of MESCC and should facilitate referral of patients with MESCC for surgical evaluation.

Plication of a nonfunctional hemidiaphragm usually restores altered ventilatory mechanics. This study compared two techniques in performing diaphragmatic plication: video-assisted thoracoscopy (group A) and thoracotomy (group B). Twenty dogs with induced paralysis of the right hemidiaphragm were randomly assigned to one of the two groups. Evaluations were performed before and after plication of the respiratory frequency (f) and lung area (LA) of the affected side. Operative time, time to resumption of walking, ingestion of fluids and solid food, pain intensity, and postoperative complications were measured. Group A had less pain after the surgery (P < 0.0001), earlier fluid ingestion (P < 0.05), and earlier resumption of walking (P < 0.019). Four weeks after the procedure, LA was similar in both groups, while a significant decrease in f was recorded in group A (P < 0.02). The remaining evaluated variables showed no differences. Both approaches were effective. Pain recorded in the postoperative period was less and recovery was faster in group A. Complications and surgical times were similar. The video-assisted thoracoscopy is a safe and efficient option for performing diaphragmatic plication in dogs.

Pain after laparoscopic cholecystectomy is mild to moderate in intensity. Several modalities are employed for achieving safe and effective postoperative analgesia, the benefits of which adds to the early recovery of the patients. As a part of multimodal analgesia, various approaches of Transversus abdominis plane (TAP) block has been used for management of parietal and incisional components of pain after laparoscopic cholecystectomy. This study was designed to compare the analgesic efficacy of two different approaches of ultrasound guided TAP block, i.e., Subcostal-TAP block technique with ultrasound guided Posterior-TAP block for postoperative pain management in patients undergoing laparoscopic cholecystectomy under general anaesthesia. In this double blinded randomized controlled study, consecutive nonprobability sampling was done and a total of 126 patients admitted for elective laparoscopic cholecystectomy fulfilling the inclusion criteria were selected. After induction of general anaesthesia, patients were randomized through draw method and received either ultrasound guided posterior TAP block with 0.375% bupivacaine (20ml volume) on each side of the abdomen or subcostal TAP block bilaterally with the same. Up to 24 hours postoperatively, static and dynamic numeric rating pain scores were assessed. We found statistically significant difference in mean static pain scores over 24 hours postoperatively in subcostal TAP group, suggesting improved analgesia. However, mean dynamic postoperative pain scores were comparable between the two groups. Whereas, patients in both groups were satisfied with pain management. Ultrasound guided subcostal TAP block provides better postoperative analgesia as compared to the Posterior TAP block in laparoscopic cholecystectomy. Otherwise both of the approaches improve patient outcomes towards early recovery and discharge from hospital.

To prospectively describe the prevalence and predictive factors of chronic postsurgical pain (CPSP) and poor global recovery in a large outpatient population at a university hospital, 1 year after outpatient surgery. A prospective longitudinal cohort study was performed. During 18 months, patients presenting for preoperative assessment were invited to participate. Outcome parameters were measured by using questionnaires at 3 timepoints: 1 week preoperatively, 4 days postoperatively, and 1 year postoperatively. A value of >3 on an 11-point numeric rating scale was considered to indicate moderate to severe pain. A score of ≤80% on the Global Surgical Recovery Index was defined as poor global recovery. A total of 908 patients were included. The prevalence of moderate to severe preoperative pain was 37.7%, acute postsurgical pain 26.7%, and CPSP 15.3%. Risk factors for the development of CPSP were surgical specialty, preoperative pain, preoperative analgesic use, acute postoperative pain, surgical fear, lack of optimism, and poor preoperative quality of life. The prevalence of poor global recovery was 22.3%. Risk factors for poor global recovery were recurrent surgery because of the same pathology, preoperative pain, preoperative analgesic use, surgical fear, lack of optimism, poor preoperative and acute postoperative quality of life, and follow-up surgery during the first postoperative year. Moderate to severe CPSP after outpatient surgery is common, and should not be underestimated. Patients at risk for developing CPSP can be identified during the preoperative phase.

Pain is known to alter the electrogalvanic properties of the skin. The aim of this pilot study was to investigate the influence of postoperative pain on skin conductance (SC) readings. After obtaining ethical approval and written informed consent, 25 postoperative patients were asked to quantify their level of pain on a numeric rating scale (NRS, 0-10) at different time points in the recovery room. As a parameter of SC, the number of fluctuations within the mean SC per second (NFSC) was recorded. Simultaneously, the NRS was obtained from patients by a different observer who was blinded to the NFSC values. Data from 110 readings of 25 patients (14 female, 11 male; 21-67 yr) were included. NFSC showed a significant correlation with the NRS (r=0.625; P<0.01), whereas heart rate and blood pressure showed no or very weak correlation with the NRS. NFSC was significantly different between patients with no (NRS=0), mild (NRS=1-3), moderate (NRS=4-5) and severe (NRS=6-10) pain (no: 0.047, mild: 0.089, moderate: 0.242, severe: 0.263; P<0.0001). Post hoc, a cut-off value for NFSC (0.1) was calculated above which a pain score >3 on the NRS was predicted with sensitivity of 89% and specificity of 74%. The severity of postoperative pain significantly influences SC. Using cut-off values, NFSC may prove a useful tool for pain assessment in the postoperative period.

Arthroscopic rotator cuff repair (ARCR) can be associated with significant postoperative pain. Concern for opioid abuse has led surgeons to identify alternative, efficacious methods of postoperative analgesia. To determine whether transcutaneous electrical nerve stimulation (TENS) can have a similarly beneficial effect after shoulder procedures, we conducted a prospective double-blinded randomized trial in patients undergoing outpatient ARCR. All patients undergoing ARCR of a full-thickness rotator cuff tear by the senior authors were identified. Patients with a history of recent narcotic use or prior narcotic abuse and those under management of a pain control specialist were excluded. Patients were randomized into 2 groups, active or placebo TENS, and used the device for 4 sessions/day for 45 minutes/session for the first postoperative week. All patients received Percocet 5/325 mg (oxycodone/acetaminophen) for use as rescue pain pills. One-week narcotic consumption and visual analog scale pain scores were compared between groups. The final analysis included 37 patients (21 active,16 placebo). Baseline and procedural differences were not different between groups. At 1 week postoperatively, patients in the active group had significantly lower pain scores (3.6 ± 2.1 vs. 5.8 ± 1.2; P= .008). Postoperative Percocet consumption during the initial 48 hours (12.8 ± 4.7 vs. 17.2 ± 6.3; P = .020) and during the first week (25.2 ± 9.9 vs. 33.8 ± 14.3; P = .037) was also significantly lower in the active group. Results from this prospective double-blinded randomized trial demonstrate that compared with placebo TENS, active TENS can result in significantly less pain and reduced opioid use in the immediate postoperative period after ARCR, suggesting that TENS may be potentially useful in a multimodal approach to managing postoperative pain.

The aim of this randomized, controlled, prospective clinical study was to determine if foraminal enlargement instrumentation during endodontic treatment is associated with more postoperative pain compared with standard nonenlargement instrumentation. Forty volunteers with a single root canal were diagnosed with asymptomatic necrosis with apical periodontitis and randomized into 2 experimental groups (ie, the control group and the foraminal enlargement group). Endodontic treatment was performed in a single visit, and volunteers were instructed to record pain intensity (ie, none, slight, moderate, and severe). Scores from 1 to 4 were attributed to each kind of pain after 12, 24, and 48 hours. The Kolmogorov-Smirnov and Student's t tests were used to determine significant differences at P < .05. No statistically significant age difference was found between the groups (P > .05, Student's t test). Postoperative pain showed no statistically significant difference between the groups at any observation period (P > .05). Also, no significant difference was observed in the mean number of analgesic tablets used between the groups (P > .05). The foraminal enlargement and nonenlargement techniques resulted in the same postoperative pain and necessity for analgesic medication. This may suggest that the use of foraminal enlargement should be performed for endodontic treatment previsibility without increasing postoperative pain.

Residual pain is a major factor in patient dissatisfaction following total hip arthroplasty or total knee arthroplasty (THA/TKA). The proportion of patients with unfavourable long-term residual pain is high, ranging from 7% to 34%. There are studies indicating that a preoperative degree of central sensitisation (CS) is associated with poorer postoperative outcomes and residual pain. It is thus hypothesised that preoperative treatment of CS could enhance postoperative outcomes. Duloxetine has been shown to be effective for several chronic pain syndromes, including knee osteoarthritis (OA), in which CS is most likely one of the underlying pain mechanisms. This study aims to evaluate the postoperative effects of preoperative screening and targeted duloxetine treatment of CS on residual pain compared with care-as-usual. This multicentre, pragmatic, prospective, open-label, randomised controlled trial includes patients with idiopathic hip/knee OA who are on a waiting list for primary THA/TKA. Patients at risk for CS will be randomly allocated to the preoperative duloxetine treatment programme group or the care-as-usual control group. The primary end point is the degree of postoperative pain 6 months after THA/TKA. Secondary end points at multiple time points up to 12 months postoperatively are: pain, neuropathic pain-like symptoms, (pain) sensitisation, pain catastrophising, joint-associated problems, physical activity, health-related quality of life, depressive and anxiety symptoms, and perceived improvement. Data will be analysed on an intention-to-treat basis. The study is approved by the local Medical Ethics Committee (METc 2014/087) and will be conducted according to the principles of the Declaration of Helsinki (64th, 2013) and the Good Clinical Practice standard (GCP), and in compliance with the Medical Research Involving Human Subjects Act (WMO). 2013-004313-41; Pre-results.

Uncontrolled postoperative pain, characteristic to abdominal hysterectomy, results in multiple complications. One of the methods for controlling postoperative pain is preemptive analgesia. Gabapentin and tramadol are both used for this purpose. This study aims to compare the effects of tramadol and gabapentin, as premedication, in decreasing the pain after hysterectomy. This clinical trial was performed on 120 eligible elective abdominal hysterectomy patients, divided in three groups of 40, receiving tramadol, gabapentin and placebo, respectively. Two hours before the surgery, the first group was given 300 mg gabapentin, the second one was given 100 mg tramadol, while the other group was given placebo, with 50 ml water. After the surgery, in case of visual analog pain scale (VAS) > 3, up to 3 mg of diclofenac suppository would be used. Pain score, nausea, vomiting, sedation, patient's satisfaction and the number of meperidine administered during 24 hours (1 - 4 - 8 - 12 - 16 - 20 - 24 hours) were recorded. If patients had VAS > 3, despite using diclofenac, intravenous meperidine (0.25 mg/kg) would be prescribed. Data were analyzed using SPSS 21 software, chi-square test, general linear model and repeated measurement. The three groups were similar regarding age and length of surgery (up to 2 hours). The average VAS, in the placebo group, was higher than in the other two groups (P = 0.0001) and the average received doses of meperidine during 24-hour time were considerably higher in placebo group, compared to the other two groups (55.62 mg in placebo, 18.75 mg in gabapentin and 17.5 mg in tramadol groups, P = 0.0001). Nausea, vomiting and sedation, in the tramadol group, were higher than in the other two groups, although they were not significant. Patients' dissatisfaction, in the placebo group, during initial hours, especially in the fourth hour, was higher (P = 0.0001). In the gabapentin and tramadol groups, the trend of changes in satisfaction score was similar. However, satisfaction in the gabapentin group, during the initial 4 hours was higher, in comparison to the tramadol group (P = 0.0001). This study revealed that prescribing gabapentin or tramadol, as premedication, was effective in reducing postoperative pain, without any concerning side-effects.

The main reason for nasal tampon placement after septoplasty is to prevent postoperative hemorrhage, while the secondary purpose is internal stabilization after operations involving the cartilaginous-bony skeleton of the nose. Silicone intranasal splints are as successful as other materials in controlling postoperative hemorrhages of septal origin. The possibility of leaving the splints intranasally for extended periods helps stabilize the septum in the midline. However, there is nothing in the literature about how long these splints can be retained inside the nasal cavity without increasing the risk of infection, postoperative complications, and patient discomfort. The current study aimed to evaluate the association between the duration of intranasal splinting and bacterial colonization, postoperative complications, and patient discomfort. Patients who had undergone septoplasty were divided into three groups according to the day of removal of the silicone splints. The splints were removed on the fifth, seventh, and tenth postoperative days. The removed splints were microbiologically cultured. Early and late complications were assessed, including local and systemic infections, tissue necrosis, granuloma formation, mucosal crusting, synechia, and septal perforation. Postoperative patient discomfort was evaluated by scoring the levels of pain and nasal obstruction. No significant difference was found in the rate of bacterial colonization among the different groups. Decreased mucosal crusting and synechia were detected with longer usage intervals of intranasal silicone splints. Postoperative pain and nasal obstruction were also diminished by the third postoperative day. Silicone splints were well tolerated by the patients and any negative effects on postoperative patient comfort were limited. In fact, prolonged splint usage intervals reduced late complications. Long-term silicone nasal splint usage is a reliable, effective, and comfortable method in patients with excessive mucosal damage and in whom long-term stabilization of the bony and cartilaginous septum is essential.

Objectives. To investigate and compare postoperative pain after one-visit root canal treatment (RCT) on teeth with vital pulps using three different obturation techniques. Study Design. Two hundred and four patients (105 men and 99 women) aged 12 to 77 years were randomly assigned into three treatments groups: cold lateral compaction of gutta-percha (LC), Thermafil technique (TT), and Backfill - Thermafil obturation technique (BT). Postoperative pain was recorded on a visual analogue scale (VAS) of 0 - 10 after 2 and 6 hours, and 1, 2, 3, 4, 5, 6 and 7 days. Data were statistically analyzed using multivariate logistic regression analysis. Results. In the total sample, 87% of patients experienced discomfort or pain in some moment between RCT and the seventh day. The discomfort experienced was weak, light, moderate and intense in 6%, 44%, 20% and 6% of the cases, respectively. Mean pain levels were 0.4 ± 0.4, 0.4 ± 0.3, and 1.4 ± 0.7 in LC, BT, and TT groups, respectively. Patients of TT group experienced a significantly higher mean pain level compared to other two groups (p < 0.0001). In TT group, all patients felt some level of pain at six hours after RCT. Conclusions. Postoperative pain was significantly associated with the obturation technique used during root canal treatment. Patients whose teeth were filled with Thermafil obturators (TT technique) showed significantly higher levels of discomfort than patients whose teeth were filled using any of the other two techniques. Key words:Postoperative pain, root-canal obturation, root-canal treatment, Thermafil. PMID:22322522
