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.

The majority of patients experience moderate-to-intense pain following ankle surgery. Early, adequate treatment of postoperative pain is desirable for optimal pain relief, which in turn may facilitate optimal pulmonary function, normal respiration pattern, rehabilitation and prevention of a chronic pain condition. In this retrospective study, we aimed to identify possible predictors of moderate-to-intense postoperative pain while in the Post Anaesthesia Care Unit (PACU) in patients operated for ankle fractures. Social demographics and clinical characteristics from admission throughout the stay in the PACU were collected from the hospital patient record system in retrospect. Pain was assessed using a Visual Analogue Scale (VAS) or a verbal Numeric Rating Scale (vNRS). A VAS/vNRS score 4-6 was classified as moderate and 7-10 as intense pain. Other factors which were investigated were time from ankle fracture to surgery, anaesthetic procedure, pre-, per- and postoperative medical treatment, radiological classification, complexity of fracture, operative technique, and time using tourniquet procedure. Data from 336 patients who underwent surgery to repair an ankle fracture between January 2009 and December 2010 were analysed. None of the following variables had a statistically significant effect on pain; age, weight, smoking, timeframe from fracture to operation, type of anaesthesia, opioids given peroperatively, complexity of the fracture, operation technique or tourniquet inflation procedure. Female sex predicted moderate-to-intense postoperative pain in the PACU with odds ratio 2.31 (95% confidence interval 1.39-3.86), P=0.001. As far as we know, this is the first study to show a sex difference in reporting pain in the first hours after surgery for ankle fracture. Female patients operated for ankle fracture report higher pain-intensity-score than male patients while in the PACU. Our findings suggest that treatment strategies to prevent high peaks of pain should

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.

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

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.

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 pain was ranked significantly lower at day 2 (P=0.016) and patients required fewer additional analgesics postoperatively on days 2 and 7 (P postoperative defecation pain is reduced compared with that of the placebo control group.

Our study quantifies the effectiveness of perioperative pain control in a cohort of patients undergoing major head and neck surgery with free flap reconstruction. Our long-term goal is to improve pain control and thereby increase mobility, decrease postoperative complications and decrease hospital stay. A retrospective analysis was performed at a tertiary, academic head and neck surgical oncology program in Calgary, Alberta, Canada from January 1, 2015 - December 31, 2015. Pain scores were recorded prospectively. Primary outcomes were frequency of postoperative pain assessments and pain intensity using the numeric rating scale. The cohort included 41 patients. Analysis was limited to pain scores recorded from postoperative days 1-14. There was an average of 7.3 pain measurements per day (SD 4.6, range 1-24) with the most frequent monitoring on postoperative days 1-4. Median pain scores ranged from 0 to 4.5 with the highest median score on postoperative day 6. The daily maximum pain scores recorded ranged from 8 to 10 with scores of 10 recorded on postoperative days 1, 2, 3, 5, 7, 8, and 10. Patients most frequently had inadequate pain control on postoperative days 1, 2, 4, and 5 with the majority occurring on postoperative day 1. Postoperative pain control could be improved at our centre. The frequency of pain assessments is also highly variable. Ongoing measurement, audit, and feedback of analgesic protocol effectiveness is an excellent first step in improving perioperative pain management in patients undergoing major head and neck cancer surgery with free flap reconstruction.

The Health Services, not only the Italian one, is under pressure because of request for improving treatment quality and the financial need for reorganization and cost-saving. It's required a rationalization of intervention, together with a careful choice of the best and cheapest techniques and the demonstration of their efficacy. The anaesthesia service activity, in a period of cost rationalization and funds restriction should be aimed to appropriate outcome measures corrected by both patient's risk factors and surgical-anaesthesiological case-mix. The development of a complete strategy for surgical pain management might run into two phases. The first phase, internal and mono-specialistic, should develop like the creation of an Acute Pain Team. The main processes are: focusing the problem (charge of the care), training, information, teaching methodology (timing, methods, drugs, techniques, etc.) and the audit (before and after changes). The main aims are the evaluation of the level of analgesia and pain relief or patient's satisfaction which are partial endpoints useful to demonstrate the improvement and the efficacy of the new pain management strategies. The second phase, multidisciplinary, is directed toward the creation of a Postoperative Evaluation Team. The main objective is to set up a collaborative clinical group able to identify the criteria for quality, efficacy and safety. The major purpose is the evaluation of major outcome measures: surgical outcome, morbidity, mortality and length of hospitalization. The improvement in the quality of postoperative pain treatment goes through a better organization and a progressive increase of the already available therapy. The achievement of the result and the quality projects depend on the interaction among staff members with different behaviours and settings.

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.

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).

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.

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.

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.

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

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.

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.

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

2015-01-01

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

BACKGROUND⁄ Pain-related misbeliefs among health care professionals (HCPs) are common and contribute to ineffective postoperative pain assessment. While standardized patients (SPs) have been effectively used to improve HCPs' assessment skills, not all centres have SP programs. The present equivalence randomized controlled pilot trial examined the efficacy of an alternative simulation method - deteriorating patient-based simulation (DPS) - versus SPs for improving HCPs' pain knowledge and assessment skills. Seventy-two HCPs were randomly assigned to a 3 h SP or DPS simulation intervention. Measures were recorded at baseline, immediate postintervention and two months postintervention. The primary outcome was HCPs' pain assessment performance as measured by the postoperative Pain Assessment Skills Tool (PAST). Secondary outcomes included HCPs knowledge of pain-related misbeliefs, and perceived satisfaction and quality of the simulation. These outcomes were measured by the Pain Beliefs Scale (PBS), the Satisfaction with Simulated Learning Scale (SSLS) and the Simulation Design Scale (SDS), respectively. Student's t tests were used to test for overall group differences in postintervention PAST, SSLS and SDS scores. One-way analysis of covariance tested for overall group differences in PBS scores. DPS and SP groups did not differ on post-test PAST, SSLS or SDS scores. Knowledge of pain-related misbeliefs was also similar between groups. These pilot data suggest that DPS is an effective simulation alternative for HCPs' education on postoperative pain assessment, with improvements in performance and knowledge comparable with SP-based simulation. An equivalence trial to examine the effectiveness of deteriorating patient-based simulation versus standardized patients is warranted.

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.

Preoperative carbohydrate (CHO) reduces perioperative insulin resistance and improves preoperative patient comfort. We tested the hypotheses that preoperative CHO reduces the risk of postoperative nausea and vomiting (PONV) and improves early postoperative patient comfort. Two hundred women scheduled for thyroidectomy were randomly allocated to drink 50 g CHO in 400 ml of water or 0.5 g aspartam in 100 ml of water 2 h before surgery. The incidence and the severity of PONV, pain scores, and analgesic consumption were recorded postoperatively. Intensity of thirst, hunger, anxiety, fatigue were recorded on 100-mm visual analog scales just before the induction of anesthesia, 2, 6, and 24 h postoperatively. The incidence and severity of PONV were similar in both groups. Patients from the CHO group reported significantly less thirst (P = 0.007), hunger (P = 0.04), and fatigue (P = 0.01) than patients from the control group. Postoperative pain scores did not differ significantly between both groups (P = 0.34). However patients from the CHO group requested less acetaminophen during the first 24 postoperative h: 3 g vs. 2 g (median, P = 0.002). Oral carbohydrate before thyroidectomy improves pre- and postoperative patient comfort, as well as postoperative analgesia, but has no effect on the PONV.

Postoperative pain slows surgical recovery, impacting the return of normal function for weeks, months, or longer. Here we report the antihyperalgesic actions of a new compound, resolvin D1 (RvD1), known to reduce inflammation and to suppress pain after peripheral nerve injury, on the acute pain occurring after paw incision and the prolonged pain after skin-muscle retraction. Injection of RvD1 (20–40 ng) into the L5–L6 intrathecal space 30 minutes before surgery reduces the postincisional primary mechanical hypersensitivity, lowering the peak change by approximately 70% (with 40 ng) and reducing the area under the curve (AUC) for the entire 10-day postincisional course by approximately 60%. Intrathecal injection of RvD1 on postoperative day (POD) 1 reduces the hyperalgesia to the same level as that from preoperative injection within a few hours, an effect that persists for the remaining PODs. Tactile allodynia and hyperalgesia following the skin/muscle incision retraction procedure, measured at the maximum values 12 to 14 days, is totally prevented by intrathecal RvD1 (40 ng) given at POD 2. However, delaying the injection until POD 9 or POD 17 results in RvD1 causing only transient and incomplete reversal of hyperalgesia, lasting for <1 day. These findings demonstrate the potent, effective reduction of postoperative pain by intrathecal RvD1 given before or shortly after surgery. The much more limited effect of this compound on retraction-induced pain, when given 1 to 2 weeks later, suggests that the receptors or pathways for resolvins are more important in the early than the later stages of postoperative pain.

The objective of this narrative review was to examine the usage of ketamine as a postoperative analgesic agent across a wide variety of surgeries. 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. 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. 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.

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.

Background. Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery. Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery. Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group. Results. Pain scores recorded 4 h, 5 h, 6 h, 7 h, and 8 h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay. Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy. This trial is registered with Clinicaltrials.gov number NCT02725229. PMID:27445610

Foot and hand massage as an intervention for postoperative pain.

2004-06-01

Physiological responses to pain create harmful effects that prolong the body's recovery after surgery. Patients routinely report mild to moderate pain even though pain medications have been administered. Complementary strategies based on sound research findings are needed to supplement postoperative pain relief using pharmacologic management. Foot and hand massage has the potential to assist in pain relief. Massaging the feet and hands stimulates the mechanoreceptors that activate the "nonpainful" nerve fibers, preventing pain transmission from reaching consciousness. The purpose of this pretest-posttest design study was to investigate whether a 20-minute foot and hand massage (5 minutes to each extremity), which was provided 1 to 4 hours after a dose of pain medication, would reduce pain perception and sympathetic responses among postoperative patients. A convenience sample of 18 patients rated pain intensity and pain distress using a 0 to 10 numeric rating scale. They reported decreases in pain intensity from 4.65 to 2.35 (t = 8.154, p <.001) and in pain distress from 4.00 to 1.88 (t = 5.683, p <.001). Statistically significant decreases in sympathetic responses to pain (i.e., heart rate and respiratory rate) were observed although blood pressure remained unchanged. The changes in heart rate and respiratory rate were not clinically significant. The patients experienced moderate pain after they received pain medications. This pain was reduced by the intervention, thus supporting the effectiveness of massage in postoperative pain management. Foot and hand massage appears to be an effective, inexpensive, low-risk, flexible, and easily applied strategy for postoperative pain management.

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.

The field of refractive surgery continues to evolve amid continued concerns as to which surgical technique minimizes the risk of inducing ectasia. To compare clinical outcomes between PRK, LASEK and Epi-LASIK in moderately to highly myopic eyes (-4.00 D to -8.00 D). A retrospective chart review of 100 PRK eyes, 100 LASEK eyes (with alcohol) and 97 Epi-LASIK eyes was performed. Post-operative pain, uncorrected visual acuity, and corneal haze data was recorded and analyzed at post-op days 1, 4 and 7 and at post-op months 1, 3, 6 and 12. In all groups surgical corrections ranged from -4.00 D to -8.00 D. There was less pain associated with the epi-LASIK procedure especially early (post-op days 1 and 4). Visual recovery was superior within the PRK group during the first post-operative week but by post-op week 4 all three were equal. Haze scores were similar but a trend for less haze was demonstrated with epi-LASIK at 6 and 12 months. Epi-LASIK has a slight advantage over PRK and LASEK early on in the post-op course with regards to pain. Visual recovery is similar by 4 weeks and is better with PRK early. In addition, epi-LASIK trends toward less significant haze. © Nepal Ophthalmic Society.

BACKGROUND AND PURPOSE There are limited data on the use of postoperative imaging to evaluate the cordotomy lesion. We aimed to describe the cordotomy lesion by using postoperative MR imaging in patients after percutaneous cordotomy for intractable cancer pain. MATERIALS AND METHODS Postoperative MR imaging and clinical outcomes were prospectively obtained for 10 patients after percutaneous cordotomy for intractable cancer pain. Area, signal intensity, and location of the lesion were recorded. Clinical outcomes were measured by using the Visual Analog Scale and the Brief Pain Inventory–Short Form, and correlations with MR imaging metrics were evaluated. RESULTS Ten patients (5 men, 5 women; mean age, 58.5 ± 9.6 years) were included in this study. The cordotomy lesion was hyperintense with central hypointense foci on T2-weighted MR imaging, and it was centered in the anterolateral quadrant at the C1–C2 level. The mean percentage of total cord area lesioned was 24.9% ± 7.9%, and most lesions were centered in the dorsolateral region of the anterolateral quadrant (66% of the anterolateral quadrant). The number of pial penetrations correlated with the percentage of total cord area that was lesioned (r = 0.78; 95% CI, 0.44–0.89; P = .008) and the length of T2-weighted hyperintensity (r = 0.85; 95% CI, 0.54–0.89; P = .002). No significant correlations were found between early clinical outcomes and quantitative MR imaging metrics. CONCLUSIONS We describe qualitative and quantitative characteristics of a cordotomy lesion on early postoperative MR imaging. The size and length of the lesion on MR imaging correlate with the number of pial penetrations. Larger studies are needed to further investigate the clinical correlates of MR imaging metrics after percutaneous cordotomy. PMID:28209581

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.

According to current recommendations a multimodal approach is believed to be the gold standard for postoperative pain treatment in children. However, several surveys in the last few years demonstrated that postoperative pain in children is still a serious problem, mainly because opioids are avoided. One of the reasons for this is the fear of severe adverse events following opioid administration. Tramadol is a weak mu-opioid agonist and inhibits reuptake of noradrenaline and serotonin (5HT). Because of a relatively wide therapeutic window and a ceiling effect with a lower risk for severe adverse events (for example respiratory depression) tramadol is a widely used opioid in children. However, the exact efficacy and occurrence of adverse events following tramadol (in comparison with placebo or other opioids) for postoperative pain treatment in children and adolescents are currently not clear. To assess the effectiveness and side effect profile of tramadol for postoperative pain relief in children and adolescents undergoing different surgical procedures. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 6), MEDLINE via PubMed (January 1966 to July 2014) and EMBASE via Ovid (January 1947 to July 2014). There were no restrictions regarding language or date of publication. The reference lists of all included trials were checked for additional studies. All randomised controlled clinical trials investigating the perioperative administration of tramadol compared to placebo or other opioids for postoperative pain treatment in children and adolescents were included. Three review authors independently assessed the study eligibility, performed the data extraction and assessed the risk of bias of included trials. Twenty randomised controlled trials involving 1170 patients were included in this systematic review. The overall risk of bias in included trials was assessed as unclear, because

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

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.

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.

Analgesics for orthopedic postoperative pain.

PubMed

Bourne, Michael H

2004-03-01

Postoperative pain management is critical for optimal care of orthopedic surgery patients. Opioids, administered intramuscularly, as epidurals, or IV as patient-controlled analgesia, are effective for severe pain. Adjunctive therapy and preemptive analgesia such as nerve blocks, and methods of delivery such as infusion pumps, may be used after total knee arthroplasty and anterior cruciate ligament (ACL) reconstruction. Oral opioids are effective for moderate to severe pain, and tramadol, with efficacy comparable to morphine but with fewer severe side effects, is selected for moderate to moderately severe pain. Opioid-sparing NSAIDs, such as ketorolac, and COX-2-specific NSAIDS have use in pain management of hip, knee, and ACL procedures. An individualized regimen of appropriate analgesics, combined with nonpharmacologic treatments such as physical therapy or cryotherapy and patient education, can aid orthopedic surgery patients' recovery.

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 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.

Comparison of Bupivacaine and Lidocaine Use for Postoperative Pain Control in Endodontics

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.

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.

This study investigated the use of sprayed intraperitoneal bupivacaine to relieve postoperative pain behavior and biochemical stress response after laparoscopic ovariohysterectomy (LOVH) in dogs. Sixteen sexually intact female dogs were randomly assigned to two groups. The sprayed intraperitoneal bupivacaine (SIB) group received 4.4 mg/kg of sprayed intraperitoneal bupivacaine diluted to 0.25% with an equivalent volume of saline after pneumoperitoneum. The control group received 1.76 mL/kg of saline in a similar fashion. Both groups received preoperative periportal 5% bupivacaine (1 mL) before incision. Postoperative pain was measured using the short form of the Glasgow composite measures pain scale (CMPS-SF, 0-24). Serum cortisol and glucose concentrations were measured preoperatively and 0.5, 1, 2, 4, 6, 12, and 24h postoperatively. The SIB group had significantly lower CMPS-SF compared to the control group 1, 2, 4, 6, and 12h after the operation. Cortisol concentrations were significantly increased from preoperative concentrations in the control group at 0.5, 1, 2, and 4h post operation and at 0.5 and 1h post operation in the SIB group. No significant differences were seen in serum glucose within each group. This report suggests that the use of sprayed intraperitoneal bupivacaine can be used as part of a multimodal approach for pain management after LOVH in dogs. Copyright © 2011 Elsevier Ltd.

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

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.

Postoperative pain after haemorrhoidectomy: role of impaired evacuation.

2011-08-01

We hypothesized that obstructive defaecation is associated with more postoperative pain after haemorrhoidectomy. Fifty patients with grade IV haemorrhoids were included in a prospective study. Impaired evacuation was defined as the inability to evacuate a rectal balloon. Perianal sensitivity was evaluated by means of an algometer, and anxiety and depression were assessed by the hospital anxiety and depression (HAD) scale. Over the first 10 days after a Milligan-Morgan haemorrhoidectomy, the following parameters were measured on daily questionnaires: pain (associated with and unrelated to defaecation by means of visual analogue scales), number of bowel movements, faecal consistency and analgesic requirement on demand (tramadol 50 mg p.o., number of doses). Results are expressed as median and interquartile range or mean ± SE. Patients with impaired evacuation (14 women, eight men; age range 28-61 years) experienced more postoperative pain than patients with nonimpaired evacuation (eight women, 20 men; age range 24-70 years): 3.2 (2.1) vs 2.1 (1.8) defaecatory pain, respectively (P = 0.045), and 2.4 (2.3) vs 1.7 (2.3) nondefecatory pain, respectively (P = 0.048). There was no difference between the groups regarding stool consistency, number of bowel movements [12.5 (7.3) vs 15.5 (7.2), respectively; NS] and analgesic requirement [1.0 (6.1) vs 1.0 (5.2) extra doses on demand, respectively; NS] during the 10 postoperative days. No differences related to age, sex, HAD scores or perianal sensitivity were found. Impaired anal evacuation is predictive of postoperative pain after haemorrhoidectomy. © 2011 The Authors.

Patients prescribed opioids for chronic pain may suffer from inadequate postoperative pain control. Ketamine is an adjuvant demonstrating analgesic and opioid-sparing effects. We hypothesize that an intravenous ketamine infusion in addition to opioid-based patient-controlled analgesia (PCA) improves postoperative pain relief in this patient population. We evaluated 64 patients with chronic pain taking opioids undergoing nononcologic surgery. Patients were randomized to receive either postoperative hydromorphone PCA and continuous ketamine (0.2 mg/kg/hour), or hydromorphone PCA and saline. Patients provided numeric rating scale (NRS) pain scores for "worst," "average," and "least" pain following surgery. The primary outcome measure was change in patients' postoperative NRS scores compared with baseline NRS. Secondary and tertiary outcomes included postoperative day one 24-hour opioid use and the amount of opioid used 24 hours prior to hospital discharge. Fifty-nine patients were included in the analysis. Baseline patient characteristics were similar with the exception of age. Patients using ketamine had decreased "average" pain scores (percent change between postoperative and preoperative NRS) after surgery (13.5% decrease in the ketamine group vs 15.5% increase in NRS in the placebo group, P = 0.0057). There were no differences in "worst" or "least" pain scores or postoperative opioid use. Side effects between groups were similar. Our study demonstrates that a postoperative ketamine infusion at 0.2 mg/kg/hour in addition to opioids results in a statistically significant reduction of "average" pain scores in patients undergoing surgery who take opioids for chronic pain. However, "least" and "worst" pain scores and the amount of opioid used postoperatively did not differ between groups. Thus, the use of a postoperative ketamine infusion at 0.2 mg/kg/hour provides limited benefit in improving pain management for this challenging population. Wiley Periodicals, Inc.

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.

Meehan, T C

1993-01-01

This article details Meehan's research study concerning the conceptualization of therapeutic touch within Rogers' science of unitary human beings and an investigation of the effects of therapeutic touch on pain experience in postoperative patients. Using a single trial, single-blind, three-group design, 108 postoperative patients were randomly assigned to receive one of the following: therapeutic touch, a placebo control intervention which mimicked therapeutic touch, or the standard intervention of a narcotic analgesic. Using a visual analogue scale, pain was measured before and one hour following intervention. The hypothesis, that therapeutic touch would significantly decrease postoperative pain compared to the placebo control intervention, was not supported. Secondary analyses suggest that therapeutic touch may decrease patients' need for analgesic medication. Implications for further research and practice are suggested.

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.

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.

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.

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.

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.

Use of postoperative steroids to reduce pain and inflammation.

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.

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.

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.

Post-operative pain management is a significant problem in clinical practice in Latin America. Insufficient or inappropriate pain management is in large part due to insufficient knowledge, attitudes and education, and poor communications at various levels. In addition, the lack of awareness of the availability and importance of clear policies and guidelines for recording pain intensity, the use of specific analgesics and the proper approach to patient education have led to the consistent under-treatment of pain management in the region. However, these problems are not insurmountable and can be addressed at both the provider and patient level. Robust policies and guidelines can help insure continuity of care and reduce unnecessary variations in practice. The objective of this paper is to call attention to the problems associated with Acute Post-Operative Pain (APOP) and to suggest recommendations for their solutions in Latin America. A group of experts on anesthesiology, surgery and pain developed recommendations that will lead to more efficient and effective pain management. It will be necessary to change the knowledge and behavior of health professionals and patients, and to obtain a commitment of policy makers. Success will depend on a positive attitude and the commitment of each party through the development of policies, programs and the promotion of a more efficient and effective system for the delivery of APOP services as recommended by the authors of this paper. The writing group believes that implementation of these recommendations should significantly enhance efficient and effective post-operative pain management in Latin America.

Current pain management protocols involving many anesthetic and analgesic drugs reportedly provide adequate analgesia after TKA. However, control of emetic events associated with the drugs used in current multimodal pain management remains challenging. We determined (1) whether ramosetron prophylaxis reduces postoperative emetic events; and (2) whether it influences pain levels and opioid consumption in patients managed with a current multimodal pain management protocol after TKA. We randomized 119 patients undergoing TKA to receive either ramosetron (experimental group, n = 60) or no prophylaxis (control group, n = 59). All patients received regional anesthesia, preemptive analgesic medication, continuous femoral nerve block, periarticular injection, and fentanyl-based intravenous patient-controlled analgesia. We recorded the incidence of emetic events, rescue antiemetic requirements, complete response, pain level, and opioid consumption during three periods (0-6, 6-24, and 24-48 hours postoperatively). The severity of nausea was evaluated using a 0 to 10 VAS. The ramosetron group tended to have a lower incidence of nausea with a higher complete response and tended to have less severe nausea and fewer rescue antiemetic requirements during the 6- to 24-hour period. However, the overall incidences of emetic events, rescue antiemetic requirements, and complete response were similar in both groups. We found no differences in pain level or opioid consumption between the two groups. Ramosetron reduced postoperative emetic events only during the 6- to 24-hour postoperative period and did not affect pain relief. More efficient measures to reduce emetic events after TKA should be explored. Level I, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

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

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.

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.

Preoperative dexamethasone reduces postoperative pain, nausea and vomiting following mastectomy for breast cancer

PubMed Central

2010-01-01

Background Dexamethasone has been reported to reduce postoperative symptoms after different surgical procedures. We evaluated the efficacy of preoperative dexamethasone in ameliorating postoperative nausea and vomiting (PONV), and pain after mastectomy. Methods In this prospective, double-blind, placebo-controlled study, 70 patients scheduled for mastectomy with axillary lymph node dissection were analyzed after randomization to treatment with 8 mg intravenous dexamethasone (n = 35) or placebo (n = 35). All patients underwent standardized procedures for general anesthesia and surgery. Episodes of PONV and pain score were recorded on a visual analogue scale. Analgesic and antiemetic requirements were also recorded. Results Demographic and medical variables were similar between groups. The incidence of PONV was lower in the dexamethasone group at the early postoperative evaluation (28.6% vs. 60%; p = 0.02) and at 6 h (17.2% vs. 45.8%; p = 0.03). More patients in the placebo group required additional antiemetic medication (21 vs. 8; p = 0.01). Dexamethasone treatment significantly reduced postoperative pain just after surgery (VAS score, 4.54 ± 1.55 vs. 5.83 ± 2.00; p = 0.004), at 6 h (3.03 ± 1.20 vs. 4.17 ± 1.24; p < 0.0005) and at 12 h (2.09 ± 0.85 vs. 2.54 ± 0.98; p = 0.04). Analgesics were required in more patients of the control group (21 vs. 10; p = 0.008). There were no adverse events, morbidity or mortality. Conclusions Preoperative intravenous dexamethasone (8 mg) can significantly reduce the incidence of PONV and pain in patients undergoing mastectomy with axillary dissection for breast cancer.

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.

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.

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 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.

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

PubMed

Sin, Wai Man; Chow, Ka Ming

2015-12-01

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.

Gama, Tulio G V; de Oliveira, Julio C Machado; Abad, Ernani C; Rôças, Isabela N; Siqueira, José F

2008-12-01

This study evaluated the incidence of postoperative pain after intracanal dressings with either 0.12% chlorhexidine digluconate gel (CHX) or a calcium hydroxide/camphorated paramonochlorophenol/glycerin paste (CH/CPMC). Overall, 138 asymptomatic teeth had their canals instrumented under irrigation with 2.5% NaOCl and then dressed with either CH/CPMC or CHX. The incidence of different intensity levels of postoperative pain was registered for the period between appointments. Data revealed that 84% of the total number of cases treated with either medicament showed absence of any level of pain. No case medicated with CH/CPMC and four cases (5.8%) medicated with CHX were categorized as flare-ups. There were no statistically significant differences between all possible comparisons involving the two medicaments in treatment/retreatment cases and teeth with/without apical periodontitis lesions. The low incidence of postoperative pain after the use of both medications, coupled to their antimicrobial effectiveness, gives support to using one or the other in routine treatment/retreatment.

Pre-emptive oral dextromethorphan reduces both postoperative and packing removal pain in patients undergoing nasal surgery.

2009-02-01

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.

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.

Background Dipyrone (metamizole) is a non-steroidal anti-inflammatory drug used in some countries to treat pain (postoperative, colic, cancer, and migraine); it is banned in others because of an association with life-threatening blood agranulocytosis. This review updates a 2001 Cochrane review, and no relevant new studies were identified, but additional outcomes were sought. Objectives To assess the efficacy and adverse events of single dose dipyrone in acute postoperative pain. Search methods The earlier review searched CENTRAL, MEDLINE, EMBASE, LILACS and the Oxford Pain Relief Database to December 1999. For the update we searched CENTRAL, MEDLINE,EMBASE and LILACS to February 2010. Selection criteria Single dose, randomised, double-blind, placebo or active controlled trials of dipyrone for relief of established moderate to severe postoperative pain in adults. We included oral, rectal, intramuscular or intravenous administration of study drugs. Data collection and analysis Studies were assessed for methodological quality and data extracted by two review authors independently. Summed total pain relief over six hours (TOTPAR) was used to calculate the number of participants achieving at least 50% pain relief. Derived results were used to calculate, with 95% confidence intervals, relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over six hours. Use and time to use of rescue medication were additional measures of efficacy. Information on adverse events and withdrawals was collected. Main results Fifteen studies tested mainly 500 mg oral dipyrone (173 participants), 2.5 g intravenous dipyrone (101), 2.5 g intramuscular dipyrone (99); fewer than 60 participants received any other dose. All studies used active controls (ibuprofen, paracetamol, aspirin, flurbiprofen, ketoprofen, dexketoprofen, ketorolac, pethidine, tramadol, suprofen); eight used placebo controls. Over 70% of participants

This study was designed to determine postoperative pain levels after ear, nose, and throat (ENT) surgery, and also to examine whether intraoperative fentanyl use during ENT surgery enhances the quality of postoperative pain control. The distribution of pain scores and rescue analgesic requirements among 198 patients undergoing ENT surgery were examined. Multivariate logistic regression analysis was performed to identify independent factors associated with moderate to severe postoperative pain (maximal pain score ≥ 5 on the numerical rating scale) and postoperative nausea and vomiting (PONV). 27.8% of patients experienced moderate to severe postoperative pain after ENT surgery. The distribution of postoperative pain levels was similar among procedures performed on different anatomical regions. Intraoperative fentanyl use was not associated with moderate to severe postoperative pain (adjusted odds ratio (95% confidence interval) :1.03 (0.51-2.13))]. On the other hand, intraoperative fentanyl use was independently associated with PONV [3.10 (1.25-8.92); P = 0.0138]. Prevalence of moderate to severe postoperative pain after ENT surgery was approximately 28%. Intraoperative fentanyl use was not associated with a decreased incidence of moderate to severe postoperative pain, but was significantly associated with PONV.

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

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.

Experience with early postoperative feeding after abdominal aortic surgery.

Abdominal aortic surgery is a form of major vascular surgery, which traditionally involves long hospital stays and significant postoperative morbidity. Experiences with transit ileus are often encountered after the aortic surgery. Thus traditional postoperative care involves delayed oral feeding until the patients regain their normal bowel activities. This report examines the feasibility of early postoperative feeding after abdominal aortic aneurysm (AAA) open-repair. From May 2002 through May 2003, 10 consecutive patients with infrarenal AAA who underwent elective surgical open-repair by the same surgeon in our department were reviewed. All of them had been operated upon and cared for according to the early feeding postoperative care protocol, which comprised of adjuvant epidural anesthesia, postoperative patient controlled analgesia, early postoperative feeding and early rehabilitation. The postoperative recovery and length of hospital stay were reviewed and analyzed. All patients were able to sip water within 1 day postoperatively without trouble (Average; 12.4 hours postoperatively). All but one patient was put on regular diet within 3 days postoperatively (Average; 2.2 days postoperatively). The average postoperative length of stay in hospital was 5.8 days. No patient died or had major morbidity. Early postoperative feeding after open repair of abdominal aorta is safe and feasible. The postoperative recovery could be improved and the length of stay reduced by simply using adjuvant epidural anesthesia during surgery, postoperative epidural patient-controlled analgesia, early feeding, early ambulation, and early rehabilitation. The initial success of our postoperative recovery program of aortic repair was demonstrated.

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.

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.

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.

Background Postoperative (PO) pain interferes with the recovery and mobilization of the surgical patients. The impact of the educational status has not been studied adequately up to now. Methods This prospective study involved 400 consecutive general surgery patients. Various factors known to be associated with the perception of pain including the educational status were recorded as was the preoperative and postoperative pain and the analgesia requirements for the 1st PO week. Based on the educational status, we classified the patients in 3 groups and we compared these groups for the main outcomes: i.e. PO pain and PO analgesia. Results There were 145 patients of lower education (junior school), 150 patients of high education (high school) and 101 of higher education (university). Patients of lower education were found to experience more pain than patients of higher education in all postoperative days (from the 2nd to the 6th). No difference was identified in the type and quantity of the analgesia used. The subgroup analysis showed that patients with depression and young patients (< 40 years) had the maximum effect. Conclusions The educational status may be a significant predictor of postoperative pain due to various reasons, including the poor understanding of the preoperative information, the level of anxiety and depression caused by that and the suboptimal request and use of analgesia. Younger patients (< 40), and patients with subclinical depression are mostly affected while there is no impact on patients over 60 years old. PMID:26495081

Postoperative (PO) pain interferes with the recovery and mobilization of the surgical patients. The impact of the educational status has not been studied adequately up to now. This prospective study involved 400 consecutive general surgery patients. Various factors known to be associated with the perception of pain including the educational status were recorded as was the preoperative and postoperative pain and the analgesia requirements for the 1(st) PO week. Based on the educational status, we classified the patients in 3 groups and we compared these groups for the main outcomes: i.e. PO pain and PO analgesia. There were 145 patients of lower education (junior school), 150 patients of high education (high school) and 101 of higher education (university). Patients of lower education were found to experience more pain than patients of higher education in all postoperative days (from the 2(nd) to the 6(th)). No difference was identified in the type and quantity of the analgesia used. The subgroup analysis showed that patients with depression and young patients (< 40 years) had the maximum effect. The educational status may be a significant predictor of postoperative pain due to various reasons, including the poor understanding of the preoperative information, the level of anxiety and depression caused by that and the suboptimal request and use of analgesia. Younger patients (< 40), and patients with subclinical depression are mostly affected while there is no impact on patients over 60 years old.

Postoperative pain management in the postanesthesia care unit: an update

PubMed Central

Luo, Jie; Min, Su

2017-01-01

Acute postoperative pain remains a major problem, resulting in multiple undesirable outcomes if inadequately controlled. Most surgical patients spend their immediate postoperative period in the postanesthesia care unit (PACU), where pain management, being unsatisfactory and requiring improvements, affects further recovery. Recent studies on postoperative pain management in the PACU were reviewed for the advances in assessments and treatments. More objective assessments of pain being independent of patients’ participation may be potentially appropriate in the PACU, including photoplethysmography-derived parameters, analgesia nociception index, skin conductance, and pupillometry, although further studies are needed to confirm their utilities. Multimodal analgesia with different analgesics and techniques has been widely used. With theoretical basis of preventing central sensitization, preventive analgesia is increasingly common. New opioids are being developed with minimization of adverse effects of traditional opioids. More intravenous nonopioid analgesics and adjuncts (such as dexmedetomidine and dexamethasone) are introduced for their opioid-sparing effects. Current evidence suggests that regional analgesic techniques are effective in the reduction of pain and stay in the PACU. Being available alternatives to epidural analgesia, perineural techniques and infiltrative techniques including wound infiltration, transversus abdominis plane block, local infiltration analgesia, and intraperitoneal administration have played a more important role for their effectiveness and safety.

Postoperative pain is a barrier to the quality of paediatric care, the proper management of which is a challenge. Acute postoperative pain often leads to adverse functional and organic consequences that may compromise surgical outcome. Cleft lip is one of the most common craniofacial birth defects and requires surgical correction early in life. As expected after a surgical intervention in such a sensitive and delicate area, the immediate postoperative period of cleft lip repair may be associated with moderate to severe pain. Infraorbital nerve block associated with general anaesthesia has been used to reduce postoperative pain after cleft lip repair. To assess the effects of infraorbital nerve block for postoperative pain following cleft lip repair in children. We searched the following databases: Cochrane Central Register of Controlled Trials (CENTRAL, the Cochrane Library, Issue 6, 2015), MEDLINE, EMBASE, and Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) from inception to 17 June 2015. There were no language restrictions. We searched for ongoing trials in the following platforms: the metaRegister of Controlled Trials; ClinicalTrials.gov (the US National Institutes of Health Ongoing Trials Register), and the World Health Organization International Clinical Trials Registry Platform (on 17 June 2015). We checked reference lists of the included studies to identify any additional studies. We contacted specialists in the field and authors of the included trials for unpublished data. We included randomised controlled clinical trials that tested perioperative infraorbital nerve block for cleft lip repair in children, compared with other types of analgesia procedure, no intervention, or placebo (sham nerve block). We considered the type of drug, dosage, and route of administration used in each study. For the purposes of this review, the term 'perioperative' refers to the three phases of surgery, that is preoperative, intraoperative, and

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.

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.

Symptomatic knee joint effusion is frequently observed after hip fracture, which may lead to postoperative knee pain during rehabilitation after hip fracture surgery. However, unfortunately, very little has been reported on this phenomenon in the literature. The purpose of the current study was to investigate the relationship between symptomatic knee effusion and postoperative knee pain and to clarify the reason of the effusion accompanied by hip fracture. A total of 100 patients over 65 years of age with an acute hip fracture after fall were prospectively followed up. Knee effusion was assessed on admission and at the operating room before the surgery. If knee effusion was observed at the time of the surgery, synovial fluid was collected into syringes to investigate the cause of the effusion using a compensated polarized light microscope. Furthermore, for each patient, we evaluated age, sex, radiographic knee osteoarthritis (OA), type of the fracture, laterality, severity of the fracture, and postoperative knee pain during rehabilitation. These factors were compared between patients with and without knee effusion at the time of the surgery. As a statistical analysis, we used Mann-Whitney U-test for patients' age and categorical variables were analyzed by chi-square test or Fisher's exact test. A total of 30 patients presented symptomatic knee effusion at the time of the surgery. In patients with knee effusion, numbers of intertrochanteric fracture, radiographic knee OA, and postoperative knee pain were significantly large compared to those without effusion. In terms of synovial fluid analysis, calcium pyrophosphate dihydrate crystals were observed in 80% of patients with knee effusion. From our study, approximately 63% of patients with knee effusion at the time of the surgery had postoperative knee pain. In addition, this effusion was basically related to pseudogout.

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.

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.

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.

Single dose oral naproxen and naproxen sodium for acute postoperative pain (Review)

2014-01-01

Background Postoperative pain is often poorly managed. Treatment options include a range of drug therapies such as non-steroidal anti-inflammatory drugs (NSAIDs) of which naproxen is one. Naproxen is used to treat a variety of painful conditions including acute postoperative pain, and is often combined with sodium to improve its solubility for oral administration. Naproxen sodium 550 mg (equivalent to 500 mg of naproxen) is considered to be an effective dose for treating postoperative pain but to date no systematic review of the effectiveness of naproxen/naproxen sodium at different doses has been published. Objectives To assess the efficacy, safety and duration of action of a single oral dose of naproxen or naproxen sodium for acute postoperative pain in adults. Search strategy We searched The Cochrane Library, MEDLINE, EMBASE and the Oxford Pain Relief Database for relevant studies. Additional studies were identified from the reference list of retrieved reports. The most recent search was undertaken in July 2004. Selection criteria Included studies were randomised, double blind, placebo-controlled trials of a single dose of orally administered naproxen or naproxen sodium in adults with moderate to severe acute postoperative pain. Data collection and analysis Pain relief or pain intensity data were extracted and converted into dichotomous information to give the number of patients with at least 50% pain relief over four to six hours. Relative risk estimates (RR) and the number-needed-to-treat (NNT) for at least 50% pain relief were then calculated. Information was sought on the percentage of patients experiencing any adverse event, and the number-needed-to-harm was derived. Time to remedication was also estimated. Main results Ten trials (996 patients) met the inclusion criteria: nine assessed naproxen sodium; one combined the results from two small trials of naproxen alone. Included studies scored well for methodological quality. Meta-analysis of six trials (500

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.

This prospective randomized clinical trial evaluated the incidence of postoperative pain after glide path performed with PathFile (PF) (Dentsply Maillefer, Ballaigues, Switzerland) versus stainless-steel K-file (KF). In 149 subjects, the mechanical glide path was performed with nickel-titanium (NiTi) rotary PF; in 146 subjects, the manual glide path was performed with stainless-steel KFs. Postoperative pain, analgesics consumption, and the number of days to complete pain resolution were evaluated in the following 7 days. An analysis of variance model for repeated measures was used to compare the variation of pain-scale values (P < .05). The Student's t test for continuous variables normally distributed, the nonparametric Mann-Whitney U test for the nonnormally distributed variables, and the chi-square test for dichotomous variables were used (P < .05). Despite homogeneous baseline conditions at diagnosis, tooth type, pain prevalence, and scores, the postoperative pain prevalence curves in PF group evidenced a more favorable trend in terms of time to pain resolution compared with the KF group (P = .004). The difference was also evident in the model adjusted for analgesics consumption in both groups (P = .012). The mean analgesics intake per subject was significantly higher in the KF group (3.7 ± 2.2) compared with the PF group (2 ± 1.7) (P < .001). Mean pain stop values were also significantly higher in the KF group (2.7) compared with the PF group (1.7) (P = .001). The glide path with NiTi Rotary PF leads to less postoperative pain and faster symptom resolution. Copyright © 2012 American Association of Endodontists. Published by Elsevier Inc.

Background Flurbiprofen is a non-selective non-steroidal anti-inflammatory drug (NSAID), related to ibuprofen and naproxen, used to treat acute and chronic painful conditions. There is no systematic review of its use in acute postoperative pain. Objectives To assess efficacy, duration of action, and associated adverse events of single dose oral flurbiprofen in acute postoperative pain in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to January 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered flurbiprofen in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk (RR) and number needed to treat to benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. Main results Eleven studies compared flurbiprofen (699 participants) with placebo (362 participants) in studies lasting 6 to 12 hours. Studies were of adequate reporting quality, and most participants had pain following dental extractions. The dose of flurbiprofen used was 25 mg to 100 mg, with most information for 50 mg and 100 mg. The NNT for at least 50% pain relief over 4 to 6 hours for flurbiprofen 50 mg compared with placebo (692 participants) was 2.7 (2.3 to 3.3) and for 100 mg (416 participants) it was 2.5 (2.0 to 3.1). With flurbiprofen 50 mg and 100 mg 65% to 70% of participants experienced at least 50% pain relief, compared with 25% to 30% with placebo. Rescue medication was used by 25

The aim was to evaluate the effectiveness of topical cyclopentolate following pterygium surgery for post-operative ocular pain. All participants had nasal pterygium and underwent pterygium excision and conjunctival autografting with fibrin glue. Participants were randomised into two groups. Participants in group 1 received one per cent cyclopentolate eye drops and artificial tears upon completing surgery and were prescribed self-administered drops three times daily for three days, while participants in group 2 received a control (artificial tears) in a manner identical to group 1. Data were gathered regarding post-operative pain intensity experienced during each of the three days. Pain was graded from zero to 10 according to a visual analogue scale, in which zero signified no pain and 10 signified severe, unbearable pain. This study analysed data regarding 38 participants in group 1 and 40 participants in group 2. Results were defined as median with interquartile range (IQR); median of the pain scores at days one, two and three were as follows, respectively: 4 (IQR 2), 2.5 (IQR 1) and 2 (IQR 1.25) for group 1 and 5 (IQR 1), 3 (IQR 1.75) and 3 (IQR 1) for group 2. Pain scores were significantly lower for group 1 compared with group 2 at days one, two and three (p < 0.05). Topical cyclopentolate seems to be effective and well tolerated following pterygium surgery for post-operative ocular pain. © 2017 Optometry Australia.

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).

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

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.

To describe patients' and nurses' knowledge and beliefs regarding pain management. Moreover, to explore the effect of information and education on patients' and nurses' knowledge and beliefs regarding pain management. In the treatment of postoperative pain, patients' and nurses' inadequate knowledge and erroneous beliefs may hamper the appropriate use of analgesics. A randomised controlled trial and a cross-sectional study. In 2013, half of 760 preoperative patients were allocated to the intervention group and received written information about the complications of postoperative pain. The knowledge and beliefs of 1184 nurses were studied in 2014 in a cross-sectional study. All data were collected with the same questionnaires. In the intervention group, patients' knowledge level was significant higher than in the control group, while no differences were found in beliefs. Nurses had higher knowledge and more positive beliefs towards pain management compared with both patient groups. Nurses with additional pain education scored better than nurses without additional pain education. Nurses were also asked what percentage of pain scores matched their impression of the patient's pain, and the mean was found to be 63%. Written information was effective for increasing patients' knowledge. However, it was not effective for changing beliefs about analgesics and patients and nurses had erroneous beliefs about analgesics. It is necessary to continue to inform patients and nurses about the need for analgesics after surgery. Such education could also emphasise that a discrepancy between a patient's reported pain score and the nurse's own assessment of the patient's pain should prompt a discussion with the patient about his/her pain. © 2017 John Wiley & Sons Ltd.

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.

The aim of this study was to assess the influence of iv tramadol on opioid requirement in the early postoperative period. The subjects were 90 patients scheduled for colon surgery (hemicolectomy) who received general anesthesia using the (N2O/O2) isoflurane technique. Thirty patients (group I) were administered 100 mg of tramadol iv before induction of general anesthesia (preemptive analgesia). Group II (30 patients) was administered 100 mg of tramadol iv immediately after peritoneal closure (preventive analgesia) and control group (30 patients) received 100 mg of tramadol iv immediately after operation. Following the operation, all patients were administered tramadol in the PCA-iv mode in order to treat postoperative pain. In the postoperative period, the following parameters were measured: pain intensity (using VAS), total consumption of tramadol, time until the first PCA activation, and frequency of side effects (drowsiness, nausea, vomiting). In patients of groups I and II who had received preemptive or preventive analgesia, a significantly lower total consumption of tramadol, as compared with control group, was observed in the early postoperative period. However, the time until the first PCA activation was significantly shorter in group I as compared to the other two groups. No significant differences between the groups were found regarding pain intensity and frequency of side effects.

Pulsed electromagnetic fields (PEMF) reduce postoperative pain and narcotic requirements in breast augmentation, reduction, and reconstruction patients. PEMF enhances both calmodulin-dependent nitric oxide and/or cyclic guanosine monophosphate signaling and phosphodiesterase activity, which blocks cyclic guanosine monophosphate. The clinical effect of these competing responses on PEMF dosing is not known. Two prospective, nonrandomized, active cohorts of breast reduction patients, with 15 min PEMF per 2 h; "Q2 (active)", and 5 min PEMF per 20 min; "5/20 (active)", dosing regimens were added to a previously reported double-blind clinical study wherein 20 min PEMF per 4 h, "Q4 (active)", dosing significantly accelerated postoperative pain reduction compared with Q4 shams. Postoperative visual analog scale pain scores and narcotic use were compared with results from the previous study. Visual analog scale scores at 24 h were 43% and 35% of pain at 1 h in the Q4 (active) and Q2 (active) cohorts, respectively (P < 0.01). Pain at 24 h in the 5/20 (active) cohort was 87% of pain at 1 h, compared with 74% in the Q4 (sham) cohort (P = 0.451). Concomitantly, narcotic usage in the 5/20 (active) and Q4 (sham) cohorts was not different (P = 0.478), and 2-fold higher than the Q4 (active) and Q2 (active) cohorts (P < 0.02). This prospective study shows Q4/Q2, but not 5/20 PEMF dosing, accelerated postoperative pain reduction compared with historical shams. The 5/20 (active) regimen increases NO 4-fold faster than the Q4 (active) regimen, possibly accelerating phosphodiesterase inhibition of cyclic guanosine monophosphate sufficiently to block the PEMF effect. This study helps define the dosing limits of clinically useful PEMF signals. Copyright © 2015 Elsevier Inc. All rights reserved.

To determine the levels of agreement among first- and second-year veterinary students and experienced anesthesiologists in assessing postoperative pain in dogs from video-recordings. Cross-sectional study. Twenty-seven veterinary students, five anesthesiologists and 13 canine clinical patients. Prior to their enrolment in a core anesthesia course, veterinary students volunteered to watch 13 90 second videos of dogs. Dogs were hospitalized in an intensive care unit after a variety of surgical procedures. Students were asked to score the level of the dogs' pain using the Dynamic Interactive Visual Analog Scale and the Short Form of the Glasgow Composite-Measure Pain Scale. The same videotapes were scored by five board-certified anesthesiologists. The differences and agreement between the ratings of anesthesiologists and students, and first- and second-year students were determined with Mann-Whitney U-tests and Fleiss' or Cohen's kappa, respectively. Pain scores assigned by students and anesthesiologists differed significantly (p < 0.01). Students assigned higher pain scores to dogs that were given low pain scores by anesthesiologists, and lower pain scores to dogs deemed to be in more pain by anesthesiologists. On average, students assigned higher scores on both scales. Veterinary students early in their training assigned pain scores to dogs that differed from scores assigned by experienced anesthesiologists. © 2015 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

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.

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.

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

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.

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.

(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

Overall pain prevalence in paediatric patients is well documented, but relatively little attention has been paid to pain prevalence and intensity on specific postoperative days within the first week following an operation. To evaluate reported pain prevalence on the day of surgery and each day during the following week and to analyse pain trajectories. Retrospective study. Single centre university hospital. 815 postoperative children and adolescents (age≤18 years) were included (female: 36%, age 9.8±5.8). Children with ear, nose, throat (e.g. tonsillectomy), eye (e.g. strabismus repair) or dental surgery (e.g. dental extraction) were treated at other departments and therefore were not included in this study. Retrospective analysis of the overall and clinically relevant (pain score ≥4/10) postoperative pain prevalence in children and adolescents during the first week after surgery. Possible influencing factors (age, sex, body mass index, type of anaesthesia, type of surgery and duration of surgery) on pain trajectories are analysed using mixed model techniques. Overall, 36% of 815 analysed children and adolescents suffered from pain ≥4 during their entire hospital stay. Compared to the day of surgery, the number of patients with pain ≥4 was slightly higher on day 1 after surgery (21% vs. 25%, respectively). In self-reported pain intensity rating (done for patients age≥4 years) the type of surgery (p<.001) was the only significant variable influencing pain intensity. In observational pain assessment (age<4 years) pain scores increased with patient's age (p=.004). In this patient group, pain intensity ratings did not differ between types of surgery (p=.278). Type of surgery is an important predictor for self-reported pain intensity ratings in children but not for observational pain assessment in younger children. In younger children observational pain assessment ratings increase with age. Copyright © 2016 Elsevier Ltd. All rights reserved.

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).

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

General anesthesia and postoperative pain management in analgesic intolerant patients with/without asthma: is it safe?

Analgesic intolerance (AI) appears in approximately 1 % of the general population. The triad of bronchial asthma, nasal polyposis, and analgesic intolerance is called analgesic-induced asthma (AIA). These patients are frequently referred to adult allergy clinics for preoperative evaluation for possible analgesic cross reactivity and intolerance to anesthetic agents. To determine allergic problems related to anesthesia and postoperative pain management in AI patients with and without asthma. The medical records of 45 patients who had been diagnosed with AI between January 1991 and December 2002 in the adult allergy unit and who underwent surgery in the same hospital in the last 4 years were retrospectively analyzed. The mean age of the patients was 44.4 13.4 years and 30 (66.6 %) were female. Thirty-six (80 %) had AIA, 34 (75.6 %) had persistent allergic rhinitis and 21 (46.7 %) had nasal polyps. Fifty-one surgical procedures were performed in 45 patients, in whom ear, nose and throat surgery was the main procedure (64.7 %). Anesthesia was induced with propofol, fentanyl, and vecuronium and was maintained by sevoflurane or isoflurane. Fentanyl was used for early postoperative pain relief. No complications appeared in relation to anesthesia or early pain management except in a 44-year-old AIA woman who had a reaction in the postoperative period after receiving an inappropriate analgesic. None of the patients had anesthesia-related allergic problems. Atropine and diazepam in the premedication, propofol and fentanyl during induction, muscle relaxation facilitation by vecuronium, and sevoflurane or isoflurane for maintenance seem to be a safe general anesthetic choice for analgesic intolerant patients with and without asthma.

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

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.

Gabapentin Does Not Appear to Improve Postoperative Pain and Sleep Patterns in Patients Who Concomitantly Receive Regional Anesthesia for Lower Extremity Orthopedic Surgery: A Randomized Control Trial

PubMed Central

Amin, Shawn; Reilly, Mark C.; Shulman, Steven

2017-01-01

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

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

Surgical intervention has traditionally been reserved as the last management option for pain in chronic pancreatitis. Recently, there has been a call for surgery to be offered earlier in the disease process. The objectives of this review were to evaluate the effect of early surgery on postoperative pain, pancreatic function, and re-intervention rates in chronic pancreatitis. A systematic literature search through EMBASE, Cochrane Review, and PubMed from January 1950 to January 2014 was conducted. Citations found in relevant papers are hand-searched. Data which could be pooled were analyzed using Revman (v5.2). Risk of bias analysis was conducted. Of the 2,886 potentially eligible studies identified, 11 studies met the inclusion criteria. There was large heterogeneity in the study designs, and studies were conducted over a lengthy time span. Seven studies examined pain, three studies examined pancreatic function, and three studies examined rates of re-intervention. Meta-analysis of the three studies with comparative raw data regarding complete pain relief showed that early surgery was associated with an increased likelihood of complete postoperative pain relief (RR = 1.67, 95% CI 1.09-2.56, p = 0.02). Early surgery was also associated with reduced risk of pancreatic insufficiency and low re-intervention rates. Data from this study supports considering early surgery for pain management in patients with chronic pancreatitis, with the potential of a reduced risk of pancreatic insufficiency and the need for further intervention. Further prospective randomized studies are warranted comparing early surgery against conservative step-up approaches.

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. The aim of this study was to characterize and critically appraise the content and functionality of commercially available postoperative pain self-management apps. 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. A total of 10 apps met the inclusion criteria. All

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.

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

Background Diclofenac is a non-steroidal anti-inflammatory drug (NSAID), available as a potassium salt (immediate-release) or sodium salt (delayed-release). This review updates an earlier review published in The Cochrane Database of Systematic Reviews (Issue 2, 2004) on ‘Single dose oral diclofenac for postoperative pain’. Objectives To assess single dose oral diclofenac for the treatment of acute postoperative pain. Search methods Cochrane CENTRAL, MEDLINE, EMBASE, Biological Abstracts, the Oxford Pain Relief Database, and reference lists of articles were searched; last search December 2008. Selection criteria Randomised, double-blind, placebo-controlled clinical trials of single dose, oral diclofenac (sodium or potassium) for acute postoperative pain in adults. Data collection and analysis Two review authors independently assessed studies for inclusion and quality, and extracted data. The area under the pain relief versus time curve was used to derive the proportion of participants with at least 50% pain relief over 4 to 6 hours, using validated equations. Relative benefit (risk) and number needed to treat to benefit (NNT) were calculated. Information on adverse events, time to remedication, and participants needing additional analgesia was also collected. Main results Fifteen studies (eight additional studies) with 1512 participants more than doubled the information available at each dose. Overall 50% to 60% of participants experienced at least 50% pain relief over 4 to 6 hours at any dose with diclofenac, compared to 10 to 20% with placebo, giving NNTs of about 2.5 for doses of 25 mg to 100 mg (similar to earlier review); no dose response was demonstrated. At 50 mg and 100 mg, NNTs for diclofenac potassium (2.1 (1.8 to 2.4) and 1.9 (1.7 to 2.2)) were significantly lower (better) than for diclofenac sodium (6.7 (4.2 to 17) and 4.5 (3.2 to 7.7)). The median time to use of rescue medication was 2 hours for placebo, 4.3 hours for diclofenac 50 mg and 4.9 hours

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.

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.

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.

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 pain following gynecological laparoscopic surgery is less intense than that following open surgery; however, patients often experience visceral pain after the former surgery. The aim of this study was to determine the effects of preemptive ketamine on visceral pain in patients undergoing gynecological laparoscopic surgery. Ninety patients undergoing gynecological laparoscopic surgery were randomly assigned to one of three groups. Group 1 received placebo. Group 2 was intravenously injected with preincisional saline and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. Group 3 was intravenously injected with preincisional ketamine (0.3 mg/kg) and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. A standard anesthetic was used for all patients, and meperidine was used for postoperative analgesia. The visual analogue scale (VAS) scores for incisional and visceral pain at 2, 6, 12, and 24 h, cumulative analgesic consumption and time until first analgesic medication request, and adverse effects were recorded postoperatively. The VAS scores of visceral pain in group 3 were significantly lower than those in group 2 and group 1 at 2 h and 6 h postoperatively (P<0.05 and P<0.01, respectively). At 2 h and 6 h, the VAS scores of incisional pain did not differ significantly between groups 2 and 3, but they were significantly lower than those in group 1 (P<0.01). Groups 1 and 2 did not show any differences in visceral pain scores at 2 h and 6 h postoperatively. Moreover, the three groups showed no statistically significant differences in visceral and incisional pain scores at 12 h and 24 h postoperatively. The consumption of analgesics was significantly greater in group 1 than in groups 2 and 3, and the time to first request for analgesics was significantly longer in groups 2 and 3 than in group 1, with no statistically significant difference between groups 2 and 3. However, the three groups showed no significant difference

Ketorolac use has significantly expanded for postoperative pain management since it first became available in the United States, primarily due to well established effects on patient pain scores and its ability to reduce perioperative opioid requirements. As an inhibitor of cyclooxygenase, ketorolac use has raised clinical concern including particular controversy regarding its potential effects on bone healing, postoperative kidney function and perioperative bleeding. To review the supporting data from clinical studies addressing the safety of ketorolac use for postoperative pain. This review highlights the most up-to-date research from clinical trials as well as from retrospective studies and meta-analyses regarding the effects of perioperative use of ketorolac on bone healing, kidney function and blood loss. Based on the most up-to-date literature, ketorolac in normal doses has been demonstrated to be safe with respect to bone healing. In patients with normal kidney function, numerous studies have established the safety of Ketorolac; however other studies have raised safety concerns in patients with comorbid kidney, heart and liver disease. While there is evidence that ketorolac may cause prolonged bleeding time and may be associated with increased postoperative blood loss after tonsillectomy, large scale prospective randomized controlled trials and subsequent meta-analyses have failed to establish an association of ketorolac use and perioperative blood loss. Perioperative administration of ketorolac has been demonstrated to be safe and effective in healthy patients and is particularly beneficial as an opioid-sparing agent in vulnerable patient groups. However, in certain surgical and medical contexts, proper patient selection based on the multidisciplinary collaboration between perioperative clinician specialists will optimize patient safety and pain management outcomes.

The objective of the present work was to study peculiarities of the analgesic action of therapeutic electrical stimulation (TES therapy) in the early postoperative period in the patients who underwent tonsillectomy. A total of 60 patients admitted for this surgery to the specialized otorhinolaryngological department were available for observation. They were divided into two groups depending on the pain relief strategy. The patients of the study group (n=30) underwent courses of transcranial electrical stimulation on a daily basis (from the onset of hospitalization) in addition to the administration of a standard analgetic. The standard dose of tramadol (2.0 ml) was given to the patients of the control group (n=30) who complained of strong pain. The results of the objective and subjective estimations indicate that the degree of pharyngeal pain in the patients treated with TES therapy and the standard analgetic was significantly different. The patients receiving TES therapy could sooner resume their habitual diet and required smaller amounts of the analgetic which makes this modality a cost-effective supplement to the standard postoperative treatment.

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.

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.

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.

Background This is an updated version of the original Cochrane review published in Issue 1, 2004 - this original review had been split from a previous title on ‘Single dose paracetamol (acetaminophen) with and without codeine for postoperative pain’. The last version of this review concluded that paracetamol is an effective analgesic for postoperative pain, but additional trials have since been published. This review sought to evaluate the efficacy and safety of paracetamol using current data, and to compare the findings with other analgesics evaluated in the same way. Objectives To assess the efficacy of single dose oral paracetamol for the treatment of acute postoperative pain. Search methods We searched The Cochrane Library, MEDLINE, EMBASE, the Oxford Pain Relief Database and reference lists of articles to update an existing version of the review in July 2008. Selection criteria Randomised, double-blind, placebo-controlled clinical trials of paracetamol for acute postoperative pain in adults. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Area under the “pain relief versus time” curve was used to derive the proportion of participants with paracetamol or placebo experiencing at least 50% pain relief over four to six hours, using validated equations. Number-needed-to-treat-to-benefit (NNT) was calculated, with 95% confidence intervals (CI). The proportion of participants using rescue analgesia over a specified time period, and time to use, were sought as measures of duration of analgesia. Information on adverse events and withdrawals was also collected. Main results Fifty-one studies, with 5762 participants, were included: 3277 participants were treated with a single oral dose of paracetamol and 2425 with placebo. About half of participants treated with paracetamol at standard doses achieved at least 50% pain relief over four to six hours, compared with about 20% treated with placebo. NNTs for at

Introduction: Total knee arthroplasty (TKA) is associated with intense postoperative pain for which effective analgesia is essential to facilitate early postoperative recovery. Adductor canal block (ACB) and local infiltration analgesia (LIA) have become increasingly involved in postoperative pain management after TKA. We aimed to compare their efficacy and outcomes in patients undergoing TKA. Materials and Methods: Sixty patients undergoing unilateral TKA were randomized to receive either postoperative single-injection ACB (Group A) or LIA (Group L) during the operation. All patients received spinal anaesthesia. Primary outcome was total morphine consumption over postoperative 24 hours. Visual analog pain scale, time to first and total dosage of rescue analgesia, performance-based evaluations [timed-up and go (TUG) test, quadriceps strength], side-effects, length of hospital stay and patient satisfaction were measured. Results: Fifty-seven patients were available for analysis. Median total morphine consumption over 24 and 48 postoperative hours of Group A were significantly less than Group L (6/10 mg vs 13/25 mg, p, 0.008 and 0.001, respectively). Similarly, Group A had significantly lower VAS at postoperative 6, 12 and 18 hours, VAS at ambulation on postoperative (POD) 1-3, better TUG tests on POD 2 and during POD 3 than those of Group L. However, quadriceps strength and patient satisfaction were not different between both groups. Conclusion: Patients undergoing TKA with single-injection ACB required less postoperative opioids than those with LIA. Furthermore, multimodal analgesia using ACB provided better postoperative analgesia, as well as performance-based activities, than those with LIA. PMID:29725506

The aim of this randomized clinical trial was to evaluate the influence of rotary or reciprocating retreatment techniques on the incidence, intensity, duration of postoperative pain, and medication intake. After power analysis calculations, 65 patients who needed endodontic retreatment were randomly assigned to 1 of 2 groups according to the instrumentation system used: Mtwo (VDW, Munich, Germany) or Reciproc (VDW). Retreatments were performed in a single visit by an endodontic specialist. Participants were asked to rate the incidence and intensity of the postoperative pain on a verbal rating scale 24, 48, and 72 hours after treatment. Patients were also asked to record the number of prescribed analgesic medication tablets (ibuprofen 400 mg) taken. A logistic regression analysis was used to assess both the incidence and duration of pain. Differences in the intensity of pain were analyzed using the ordinal (linear) chi-square test, and the Mann-Whitney U test was used to assess differences in the intake of analgesic medication between groups. No statistically significant difference was found among the 2 groups in relation to postoperative pain or analgesic medication intake at the 3 time points assessed (P > .05). Multivariate analysis showed a significantly higher incidence of pain after 24 hours when preoperative pain was present and a significantly longer duration of pain for men than women independently of the retreatment technique used. The reciprocating system and the continuous rotary system were found to be equivalent regarding the incidence, intensity, duration of postoperative pain, and intake of analgesic medication.

Bariatric surgery, especially in the morbidly obese, can be associated with serious postoperative problems. Apart from surgical complications requiring reoperation, pre-existing disease can worsen during the postoperative period. Bariatric patients require particular therapeutic approaches such as adapted fluid and pain management, management of obstructive sleep apnoea-hypopnea, early ambulation and measures for preventing pressure ulcers. Another challenging issue is the early identification and management of postoperative intraabdominal sepsis (IAS) before the onset of organ dysfunction. Early and frequent ambulation is thought to reduce risk of pressure ulcers, deep vein thrombosis, resedation, pain, pneumonia and atelectasis.

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

Effective postoperative analgesia after cesarean delivery enhances early recovery, ambulation, and breastfeeding. In a previous study, we established the effectiveness of the quadratus lumborum block in providing pain relief after cesarean delivery compared with patient-controlled analgesia (morphine). In the current study, we hypothesized that this method would be equal to or better than the transversus abdominis plane block with regard to pain relief and its duration of action after cesarean delivery. Between April 2015 and August 2015, we randomized 76 patients scheduled for elective cesarean delivery under spinal anesthesia to receive the quadratus lumborum block or the transversus abdominis plane block for postoperative pain relief. This trial was registered prospectively (NCT 02489851) [corrected]. Patients in the quadratus lumborum block group used significantly less morphine than the transversus abdominis plane block group (P < 0.05) at 12, 24, and 48 hours but not at 4 and 6 hours after cesarean delivery. This group also had significantly fewer morphine demands than the control group (P < 0.05) at 6, 12, 24, and 48 hours after cesarean delivery. No significant differences in visual analog scale results were shown between the 2 groups at rest or with movement. Calculated total pain relief at rest and with movement were similar (P < 0.001) in both groups. The quadratus lumborum block was more effective in reducing morphine consumption and demands than transversus abdominis plane blocks after cesarean section. This effect was observed up to 48 hours postoperatively.

Introduction: The analgesic effect of low-level laser therapy (LLLT) after mandibular third molar (MTM) extraction is controversial. The aim is to evaluate the effect of intraoral LLLT on postoperative pain after MTMs extraction. Methods: Thirty patients with bilateral symmetrical impacted MTMs underwent surgical extractions. Experimental and control sides were randomly selected to receive LLLT or placebo. Following suturing, a dental assistant applied 810 nm gallium aluminum arsenide (GaAlAs) at three points for 30 s each with a total energy of 9 J. Pain was recorded on a visual analog scale on the 7 successive days. Results: Data analyzed by IBM SPSS Statistics 23 for Windows with P ≤ 0.05 significance level. LLLT appeared to have a high significant effect on pain reduction; however, there was a mild increase in pain after the 4th day. Conclusion: Intraoral 810 nm GaAlAs is effective in reducing postoperative pain when a dose of 32.86 J/cm2 is used. PMID:29264287

Postoperative Pain Management After Primary Total Knee Arthroplasty: The Value of Liposomal Bupivacaine.

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�

Previous studies have shown that preincisional epidural morphine, bupivacaine, and ketamine combined with epidural anesthesia (EA) and general anesthesia (GA) provided pre-emptive analgesia for upper abdominal surgery. Recent studies reported that ultralow-dose naloxone enhanced the antinociceptive effect of morphine in rats. This study investigated the benefits of preincisional and postoperative epidural morphine + ropivacaine + ketamine + naloxone (M + R + K + N) treatment for achieving postoperative pain relief in upper abdominal surgery. Eighty American Society of Anesthesiology I-II patients scheduled for major upper abdominal surgery were allocated to four groups in a randomized, single-blinded study. All patients received combined GA and EA with a continuous epidural infusion of 2% lidocaine (6-8 mL/h) 30 minutes after pain regimen. After GA induction, in Group I, an epidural pain control regimen (total 10 mL) was administered using 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg; M + R); in Group II, 1% lidocaine 8 (mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg; M + R + K); in Group III, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + naloxone (2 μg; M + R + N); and in Group IV, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg) + naloxone (2 μg; M + R + K + N), respectively. All patients received patient-controlled epidural analgesia (PCEA) with different pain regimens to control subsequent postoperative pain for 3 days following surgery. During the 3-day period following surgery, PCEA consumption (mL), numerical rating scale (NRS) score while cough/moving, and analgesic-related adverse effects were recorded. Total PCEA consumption for the 3-day observation period was 161.5±17.8 mL, 103.2±21.7 mL, 152.4±25.6 mL, and 74.1±16.9 mL for Groups I, II, III, and IV, respectively. (p < 0.05).

To assess the effect of systematic local infiltration analgesia on postoperative pain in vaginal hysterectomy, and describe the technique in detail. A randomized, double-blind, placebo-controlled study following the CONSORT criteria. A university hospital. Thirty-seven patients undergoing vaginal hysterectomy. Patients received high-volume (50 mL) ropivacaine 0.50% (n = 20) or saline (n = 17) infiltration using a systematic technique ensuring uniform delivery to all tissues incised, handled or instrumented during the procedure. Pain, nausea, vomiting and opioid requirements were assessed for 32 h as well as time spent in the post-anesthesia care unit and time to first mobilization. Pain at rest was significantly reduced after one, four and eight hours in the ropivacaine group (p ≤ 0.001-0.01). Pain during coughing was significantly reduced after one and four hours (p ≤ 0.001 and p ≤ 0.003), and pain during movement was significantly reduced after four hours (p ≤ 0.02). Opioid requirements and time spent in the post-anesthesia care unit were significantly reduced in the ropivacaine group (p < 0.001 and p < 0.001, respectively), as well as the time to first mobilization (p < 0.001). Intra-operative systematic local infiltration analgesia reduces postoperative pain in patients undergoing vaginal hysterectomy, facilities mobilization and improves early recovery. © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

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.

To the best of our knowledge, the effect of pre-emptively blocking pain transmission on acute postoperative cognitive dysfunction (POCD) has not yet been assessed. Therefore, the present study aimed to investigate the effect of pre-emptive analgesia via a continuous femoral nerve block (CFNB) on postoperative pain and early cognitive function following total knee arthroplasty (TKA) surgery in elderly patients. CFNB was performed prior to TKA surgery in the pre-emptive analgesia group (n=30) and following TKA surgery in the control group (n=30). POCD was defined as a two-point reduction in the postoperative score compared with the preoperative score in the mini-mental state examination. The visual analog scale (VAS) was used to evaluate the intensity of pain at rest and during exercise. The intraoperative dose of remifentanil in the pre-emptive analgesia group was significantly lower than in the control group (P<0.01). In the preemptive analgesia group, VAS scores at three days post-surgery were lower than those in the control group (P<0.01). The incidence of POCD on the third postoperative day was slightly lower in the pre-emptive analgesia group compared with the control group. In conclusion, the results demonstrate that pre-emptive analgesia by CFNB may promote the recovery of early cognitive function following TKA in elderly patients. PMID:28413514

Summary Objectives The authors investigated the impact of computerized provider order entry (CPOE) on the delivery times of analgesia and subsequent patient outcomes. We hypothesized that patients would report less pain and use less pain medications compared with the previous paper-based system. Methods Two groups of patients after a total hip (THA) or knee arthroplasty (TKA) were retrospectively compared: one comprising 106 patients when the paper-based ordering system was in effect (conventional group), and one comprising 96 patients after CPOE was installed (electronic group). All patients received a regional anaesthetic at surgery (combined spinal-epidural). TKA patients also received a single-injection femoral nerve block. After transfer to the postoperative anaesthesia care unit (PACU), a patient-controlled epidural analgesia (PCEA) infusion was initiated. The following data was collected from the PACU record: time to initiation of analgesia, visual analog scale (VAS) pain scores at initiation of analgesia and hourly for the first postoperative day (POD), volume of pain medication used, length of stay (LOS) in the PACU and the hospital. Results The time to initiation of analgesia from arrival in the PACU was significantly lower in the electronic group compared to the conventional group (24.5 ± 28.3 minutes vs. 51.1 ± 26.2 minutes; mean ± SD, p < 0.001), as were VAS pain scores (0.82 ± 1.08 vs. 1.5 ± 1.52, p < 0.001) and the volume of PCEA needed to control pain (27.9 ± 20.2 ml vs. 34.8 ± 20.3 ml, p = 0.001) at 4 hours postoperatively. PACU LOS and hospital LOS did not significantly differ in the two groups. Conclusions After implementation of CPOE, patients received their postoperative analgesia faster, had less pain, and required less medication. PMID:26448800

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.

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.

This study aims to assess the impact of postoperative intravenous (IV) acetaminophen on opioid requirements and pain scores in patients following gynecologic procedures. A retrospective cohort study of patients undergoing gynecologic procedures was conducted to assess the impact of adding scheduled IV acetaminophen to postoperative analgesic regimens. The control group consisted of patients admitted prior to formulary addition of IV acetaminophen; the study group consisted of patients admitted after formulary addition of IV acetaminophen who received scheduled IV acetaminophen for at least the first 24 hours postoperatively. Opioid requirements 0 to 24 hours postoperatively served as the primary end point. Secondary end points included average pain score, cumulative acetaminophen dose, nonopioid analgesic requirements, and rate of adverse events 0 to 24 hours postoperatively. One hundred and thirty-seven patients who underwent a gynecologic procedure from January 2009 to April 2013 were included in this study. Baseline characteristics were similar between the groups. In the first 24 hours postoperatively, there was no difference in opioid requirements between the groups (21 mg [interquartile range, IQR, 15-39.8 mg] vs 32.6 mg [IQR, 16.75-41 mg], P = 0.150). The average pain score and incidence of adverse events did not differ between the 2 groups. Postoperative administration of IV acetaminophen did not provide a significant opioid-sparing effect in patients undergoing gynecologic procedures. © The Author(s) 2015.

Carbon monoxide (CO) is a product of burning solid fuel in stoves and smoking. Exposure to CO may provoke postoperative complications. Furthermore, there appears to be an association between COHb concentrations and pain. We thus tested the primary hypothesis that children with high preoperative carboxyhemoglobin (COHb) concentrations have more postoperative complications and pain after tonsillectomies, and secondarily that high-COHb concentrations are associated with more pain and analgesic use. 100 children scheduled for elective tonsillectomy were divided into low and high carbon monoxide (CO) exposure groups: COHb ≤3 or ≥4 g·dl(-1) . We considered a composite of complications during the 7 days after surgery which included bronchospasm, laryngospasm, persistent coughing, desaturation, re-intubation, hypotension, postoperative bleeding, and reoperation. Pain was evaluated with Wong-Baker Faces pain scales, and supplemental tramadol use recorded for four postoperative hours. There were 36 patients in the low-exposure group COHb [1.8 ± 1.2 g·dl(-1) ], and 64 patients were in the high-exposure group [6.4 ± 2.1 g·dl(-1) ]. Indoor coal-burning stoves were reported more often by families of the high- than low-COHb children (89% vs 72%, P < 0.001). Second-hand cigarette smoke exposure was reported by 54% of the families with children with high COHb, but only by 24% of the families of children with low COHb. Composite complications were more common in patients with high COHb [47% vs 14%, P = 0.0001, OR:7.4 (95% Cl, lower = 2.5-upper = 21.7)], with most occurring in the postanesthesia care unit. Pain scores in postanesthesia care unit and one hour after surgery were statistically significantly lower in the low-exposure group [respectively, P = 0.020 (95%CI, lower = -1.21-upper = -0.80), P = 0.026 (95% CI, lower = -0.03-upper = 0.70)], and tramadol use increased at 4 h (3.5 (interquartile range: 0-8) vs 6 (5-9) mg, P = 0.012) and

(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

Postoperative pain management following aesthetic plastic surgery traditionally has been achieved by systemic administration of several narcotic pain medications. Because this method can lead to undesirable side effects such as sedation, nausea, vomiting, and respiratory depression, a more efficacious method of postoperative analgesia with fewer side effects needs to be implemented in outpatient cosmetic surgery. From March of 2003 until December of 2008, 690 patients underwent augmentation mammaplasty and 215 patients underwent abdominoplasty. All of these patients were equipped with an elastomeric continuous infusion pump postoperatively and were prescribed oral narcotics. Prior to 2003, patients were prescribed only oral narcotics postoperatively. A retrospective chart review of patients before and after implementation of the pain pump was undertaken to review the perceived pain patients experienced postoperatively with and without the pump. The self-administration of oral narcotics was also assessed. Patients equipped with the pain pump experienced a statistically significant decrease in perceived pain compared to those without the pump (augmentation mammaplasty: 2.27 vs. 3.68, p < 0.05; abdominoplasty: 2.81 vs. 4.32, p < 0.05). Similarly, patients with the pump saw a statistically significant decrease in the use of the oral narcotic Vicodin™ at 72 h postoperatively (5 mg hydrocodone/500 mg acetaminophen, Abbott Laboratories, Abbott Park, IL) (augmentation mammaplasty: 26.5 mg/2650 mg vs. 49 mg/4900 mg, p < 0.01; abdominoplasty: 29.5 mg/2950 mg vs. 56.5 mg/5650 mg, p < 0.01). The utilization of a continuous-infusion pain pump following augmentation mammaplasty or abdominoplasty is an efficacious method to significantly reduce both the amount of pain patients experience and the quantity of narcotics used postoperatively.

There are reports suggesting that sensitivity to and tolerance of both clinical and experimental pain differ among ethnic groups. We examined self-rated pain score and morphine usage in 1034 women who underwent elective lower cesarian section (LSCS) for their deliveries. Data on pain scores and amount of total morphine use according to patient-controlled analgesia were collected every 4 hours. Overall, lowest pain scores were recorded 12 hours after surgery and highest at 24 hours. Morphine consumption was highest within the first 4 hours and lowest between 12 and 16 hours. There were statistically significant ethnic group differences in pain scores (P = 1.7 x 10(-7)) and morphine usage (P = 2.8 x 10(-15)) between ethnic groups, with Indians having the highest mean pain score and using the highest amount of morphine. The ethnic differences in pain score and morphine self-administration persisted after controlling for age, body mass index, and duration of operation. Our findings of highly significant ethnic group difference in self-reported pain level and the amount of analgesia self-administered may have implications on optimal management of acute postoperative pain. Inadequate management of pain after cesarian deliveries might affect the emotional well-being and physical recovery of patients and affect mother-child bonding.

This study investigates the importance of communication in surgery and how delivering preoperative patient education can lead to better health outcomes postoperatively, via promoting tolerable pain scores and minimizing the use of narcotics after surgery. Patients who underwent outpatient surgery were randomly divided into groups to compare the pain scores of those who received preoperative patient education, the experimental group, and those who did not receive any form of patient education, the control group. Two weeks before surgery, the experimental group subjects received oral and written forms of patient education consisting of how the body responds to pain, and how endorphins cause natural analgesia. Moreover, patients were educated on the negative effects narcotics have on endorphin production and activity, as well as mechanisms of non-opioid analgesics. Of the 69 patients in the experimental group, 90% declined a prescription for hydrocodone after receiving preoperative education two weeks prior to surgery. The control group consisted of 66 patients who did not receive preoperative patient education and 100% filled their hydrocodone prescriptions. Patients in both groups were offered and received gabapentin and celecoxib preoperatively for prophylaxis of postoperative pain unless they declined. The control groups were found to have average pain scores significantly greater (P <.05) than the experimental groups and also a significantly longer (P <.005) duration of pain. This study illustrates the power of patient education via oral, written and visual communication, which can serve as an effective means to minimize narcotic analgesia after surgery.

Children with cerebral palsy undergoing soft tissue and bony procedures often experience pain and spasticity postoperatively. Differentiation of pain from spasticity complicates management, so controlling spasticity with a continuous infusion of baclofen, an antispasmodic, through an already present indwelling epidural catheter holds interest. A retrospective chart review was performed of patients with cerebral palsy undergoing single event, multilevel lower extremity surgery at a single institution who received epidural analgesia with or without continuous baclofen infusion. Primary outcomes included need for supplemental narcotic analgesics and benzodiazepines postoperatively. Duration of hospitalization, pain scores, and complications were also evaluated. Forty-four patients were identified, ranging in age from 3 to 17 years, 19 of whom received epidural baclofen. No differences were found in use of supplemental narcotic analgesia, benzodiazepines, or duration of hospitalization. Differences in pain scores were not statistically significant (0.82±0.95 for baclofen vs. 1.48±0.99 for controls) (P=0.391). Mean arterial pressure was lower in patients receiving baclofen (P=0.004). No potential side effects attributable to baclofen were noted. Continuous epidural baclofen infusion seems unlikely to alter the pain-spasm cycle experienced by patients with cerebral palsy following orthopaedic surgery to a clinically significant degree. More effective, and cost-effective, measures at assessing and controlling pain and muscle spasm should be explored to benefit cerebral palsy patients postoperatively. Level III-therapeutic study.

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.

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

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

Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain. A retrospective analysis of data collected prospectively in the FAST cohort included a series of continuous patients who underwent primary repair for isolated ACL with a hamstring graft in 2013-2014. Changes in our anesthesia practices over time allowed us to form three successive groups: Group 1 - FNB, Group 2 - FNB+LIA, Group 3 - LIA only. Ultrasound-guided FNB was done pre-operatively. The LIA was done at the end of the procedure by the surgeon with systematic infiltration of all skin incisions and the hamstring donor site; no intra-articular injections were performed. The primary endpoint was the average early postoperative pain (Days 0-3) described by the patient on a visual analogue scale (0-10). Sample size calculation pointed to 36 subjects being needed per group for a non-inferiority study. The study involved 126 patients: G1=42, G2=38, G3=46. The patients were comparable at enrolment. The average early postoperative pain levels were 3.1±2.4, 2.8±2.0 and 2.5±2.2, respectively (P=0.66). A trend toward higher intake of tramadol was noted in the LIA group on D0 to D3, with a significant trend test on Day 1 (P=0.03) and Day 2 (P=0.02). After reconstruction of isolated ACL tears with a hamstring graft, FNB is not more effective than LIA on patients' early postoperative pain. Patients who received a FNB consumed significantly less opioid-like analgesics. III - Prospective, comparative, non-randomized study. Copyright © 2016 Elsevier Masson SAS. All

Postoperative pain remains a significant issue with poor perioperative pain management associated with an increased risk of morbidity and mortality. Liposomal bupivacaine is an analgesic consisting of bupivacaine hydrochloride encapsulated within multiple, non-concentric lipid bi-layers offering a novel method of sustained release. To assess the analgesic efficacy and adverse effects of liposomal bupivacaine infiltration peripheral nerve block for the management of postoperative pain. We identified randomised trials of liposomal bupivacaine peripheral nerve block for the management of postoperative pain. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 1), Ovid MEDLINE (1946 to January Week 1 2016), Ovid MEDLINE In-Process (14 January 2016), EMBASE (1974 to 13 January 2016), ISI Web of Science (1945 to 14 January 2016), and reference lists of retrieved articles. We sought unpublished studies from Internet sources, and searched clinical trials databases for ongoing trials. The date of the most recent search was 15 January 2016. Randomised, double-blind, placebo- or active-controlled clinical trials of a single dose of liposomal bupivacaine administered as a peripheral nerve block in adults aged 18 years or over undergoing elective surgery at any surgical site. We included trials if they had at least two comparison groups for liposomal bupivacaine peripheral nerve block compared with placebo or other types of analgesia. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data. We performed analyses using standard statistical techniques as described in the Cochrane Handbook for Systematic Reviews of Interventions, using Review Manager 5. We planned to perform a meta-analysis, however there were insufficient data to ensure a clinically meaningful answer; as such we have produced a 'Summary of findings' table in a narrative format, and where possible we assessed the

The analgesic efficacy and bioavailability of 30 mg intramuscular ketorolac was studied in 24 patients with severe or very severe postoperative pain. Pain and pain relief were determined by a five-point verbal rating scale and data were submitted to a probability analysis. Ketorolac plasma levels were determined by high-performance liquid chromatography. Two patients chose not to finish the study; 22 patients completed the study achieving at least good pain relief. Of these 22 patients, 13 reached complete pain relief. Ketorolac was rapidly absorbed. Notwithstanding, pain relief increased gradually, showing considerable delay with regard to plasma concentrations. Analysis of the probability-time curves revealed that 25% of the patients obtained moderate pain relief at 7 min after ketorolac administration, 50% at 11 min, 75% at 29 min, and 95% at 60 min. Good pain relief was achieved in 25, 50, and 75% of the patients at 1.1, 1.8, and 2.7 h, respectively. Complete pain relief was achieved in 25% and 50% of the patients at 2.6 h and 3.7 h, respectively. The probability of exhibiting an acceptable pain relief in responsive patients for more than 5 h was 0.97. No serious side effects were detected. Results show that 30 mg intramuscular ketorolac is an adequate treatment for postoperative pain in the Mexican population. Therefore, the use of higher doses is not justified. Due to gradual installation of analgesia, administration of additional analgesic medication before 1 h is not recommended.

Benefit-risk assessment of ropivacaine in the management of postoperative pain.

PubMed

Zink, Wolfgang; Graf, Bernhard M

2004-01-01

Ropivacaine is a long-acting amide-type local anaesthetic, released for clinical use in 1996. In comparison with bupivacaine, ropivacaine is equally effective for subcutaneous infiltration, epidural and peripheral nerve block for surgery, obstetric procedures and postoperative analgesia. Nevertheless, ropivacaine differs from bupivacaine in several aspects: firstly, it is marketed as a pure S(-)-enantiomer and not as a racemate, and secondly, its lipid solubility is markedly lower. These features have been suggested to significantly improve the safety profile of ropivacaine, and indeed, numerous studies have shown that ropivacaine has less cardiovascular and CNS toxicity than racemic bupivacaine in healthy volunteers. Extensive clinical data have demonstrated that epidural 0.2% ropivacaine is nearly identical to 0.2% bupivacaine with regard to onset, quality and duration of sensory blockade for initiation and maintenance of labour analgesia. Ropivacaine also provides effective pain relief after abdominal or orthopaedic surgery, especially when given in conjunction with opioids or other adjuvants. Nevertheless, epidurally administered ropivacaine causes significantly less motor blockade at low concentrations. Whether the greater degree of blockade of nerve fibres involved in pain transmission (Adelta- and C-fibres) than of those controlling motor function (Aalpha- and Abeta-fibres) is due to a lower relative potency compared with bupivacaine or whether other physicochemical properties or stereoselectivity are involved, is still a matter of intense debate. Recommended epidural doses for postoperative or labour pain are 20-40 mg as bolus with 20-30 mg as top-up dose, with an interval of >or=30 minutes. Alternatively, 0.2% ropivacaine can be given as continuous epidural infusion at a rate of 6-14 mL/h (lumbar route) or 4-10 mL/h (thoracic route).

To compare the emotional state during the first 3 days after coronary artery surgery of patients who had undergone early versus conventional extubation. A prospective, randomized, controlled trial. University hospital, single center. Eligible patients (n = 100) presenting for elective coronary artery surgery, randomized to an early extubation group or a conventional extubation group. Emotional status was measured by the Hospital Anxiety and Depression Scale (HAD), the Self Assessment Manikin (SAM), and the Multiple Affect Adjective Check List-Revised (MAACL-R). Tests were administered preoperatively and on the 1st and 3rd days postoperatively. Of patients in the conventional extubation group, 30% showed moderate-to-severe depressive symptoms (HAD score >10) on day 3 postoperatively compared with 8% of patients in the early extubation group (p = 0.02). There was a clinically insignificant increase in MAACL-R depression score on the 1st postoperative day within both groups but no other differences within or between groups in SAM or MAACL-R scores. Early extubation results in fewer patients displaying depressive symptoms on the 3rd postoperative day but appears to have little effect on other measurements of emotional status. Anesthetic management during coronary artery bypass graft surgery may play an important role in the overall well-being of the patient by decreasing the incidence of postoperative depression.

Tendon-bone healing after rotator cuff repair directly correlates with a successful outcome. Biological therapies that elevate local growth-factor concentrations may potentiate healing after surgery. To ascertain whether postoperative and repeated application of platelet-rich plasma (PRP) to the tendon repair site improves early tendon healing and enhances early functional recovery after double-row arthroscopic supraspinatus repair. Randomized controlled trial; Level of evidence, 1. A total of 60 patients underwent arthroscopic double-row supraspinatus tendon repair. After randomization, half the patients received 2 ultrasound-guided injections of PRP to the repair site at postoperative days 7 and 14. Early structural healing was assessed with MRI at 16 weeks, and cuff appearances were graded according to the Sugaya classification. Functional scores were recorded with the Oxford Shoulder Score; Quick Disability of the Arm, Shoulder and Hand; visual analog scale for pain; and Short Form-12 quality-of-life score both preoperatively and at postoperative weeks 6, 12, and 16; isokinetic strength and active range of motion were measured at 16 weeks. PRP treatment did not improve early functional recovery, range of motion, or strength or influence pain scores at any time point after arthroscopic supraspinatus repair. There was no difference in structural integrity of the supraspinatus repair on MRI between the PRP group (0% full-thickness retear; 23% partial tear; 77% intact) and the control group (7% full-thickness retear; 23% partial tear; 70% intact) at 16 weeks postoperatively (P = .35). After arthroscopic supraspinatus tendon repair, image-guided PRP treatment on 2 occasions does not improve early tendon-bone healing or functional recovery. © 2015 The Author(s).

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

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

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

The aim of this retrospective study was to compare immediate postoperative pain scores and need for rescue analgesia in children who underwent pulpotomies and restorative treatment and those who underwent restorative treatment only, all under general anaesthesia. Ninety patients aged between 3 and 7 years who underwent full mouth dental rehabilitation under general anaesthesia were enrolled in the study and reviewed. The experimental group included patients who were treated with at least one pulpotomy, and the control group was treated with dental fillings only. The Wong-Baker FACES scale was used to evaluate self-reported pain and need for rescue analgesia. The data were analysed using the Kruskal-Wallis test, two sample t -tests, chi-square tests, and Pearson's correlation analysis. Ninety percent of the children experienced postoperative pain in varying degrees of severity. Immediate postoperative pain scores in experimental group were found to be significantly higher than in control group ( x 2 = 24.82, p < 0.01). In the experimental group, 48% of the children needed rescue analgesia, compared with only 13% of the children in the control group ( x 2 = 13.27, p < 0.05). Children who underwent pulpotomy treatment had higher postoperative pain scores and greater need for rescue analgesia than control group who underwent only dental fillings.

It has been suggested that one of the factors related to persistent post-operative pain following total hip arthroplasty (THA) is to over sizing of the acetabular component. In order to investigate this potential issue, we retrospectively analysed a series of consecutive uncemented THA. We assessed the incidence of persistent post-operative pain and the size difference between the implanted acetabular component and the native femoral head. A total of 265 consecutive THAs were retrospectively identified. Standardised pre-operative radiographs were analysed using validated techniques to determine the native femoral head diameter. Post-operative standardised radiographs were reviewed and the acetabular orientation determined. Patients were sent postal questionnaires regarding their outcome and level of pain. Questionnaires were returned by 169 patients (189 hips, 71% response rate). A total of 17 were excluded due to inadequate radiographs., leaving 172 THA in the study group. The mean native femoral head (NFH) size was 47 mm. The most common implanted acetabular component size was 52 mm. The mean difference in cup to NFH diameter (delta) was 5.7 mm (range - 6.1 to 15.4 mm; 95% CI 5.3-6.2 mm). A delta of > 6 mm was found to be significant for predicting persistent post-operative pain (RR = 1.81; 95% CI 1.1-3.1; P = 0.027). Our study confirms that a delta of > 6 mm is associated with an increased risk of persistent post-operative pain following THA. We recommend pre-operative templating in all uncemented THA to ensure the planned acetabular component is no more than 6 mm larger than the NFH diameter.

To determine whether 400 mg of celecoxib administered 1 hour before hip arthroscopy surgery would reduce pain, provide reduction in overall narcotic consumption, and lead to more rapid discharge from recovery rooms. Ninety-eight patients were randomized to either the celecoxib group (n = 50) or the placebo group (n = 48). An a priori power analysis was done set to detect a difference of 0.50 on the visual analog scale (VAS), based on the senior author's preference. The number of patients planned for recruitment was rounded up to 100 to allow for flexibility in the study. Inclusion criteria were any patient at least 18 years old who underwent hip arthroscopy surgery performed by the senior author. All patients had less than Tönnis grade 2 arthritis. Exclusion criteria were allergy to sulfa-based drugs, prior adverse reaction to celecoxib, or patients who were on chronic narcotics for whom alternative pain management regimens were arranged before surgery. Randomization was performed on a 1:1 basis in blocks of 10 using sealed envelopes stating celecoxib or placebo. One hour before surgery, all patients received either 400 mg celecoxib or placebo. Patients were evaluated using a VAS preoperatively, immediately postoperatively, and at 1 and 2 hours postoperatively. Time from the operating room to "ready for discharge" and number of morphine equivalents of narcotic medication required in the postanesthesia care unit were recorded. Age and preoperative VAS were similar between the celecoxib and placebo control group, with average ages of 34.2 ± 11.9 and 35.8 ± 11.6 (P = .27) and preoperative VAS of 2.1 ± 2.06 and 2.3 ± 1.98 (P = .29), respectively.

Background and Objectives: In this study, 2 different varicocelectomy methods were compared with regard to postoperative scrotal pain, length of operation, and complications. Methods: Forty varicocele patients, who visited our clinic because of infertility or scrotal pain between 2008 and 2009, were enrolled in this clinical study. Microscopic subinguinal varicocelectomy was performed on 20 patients in Group I, and laparoscopic varicocelectomy was performed on 20 patients in Group II. Following surgery, the patients were assessed for postoperative requirements for analgesia; return to normal activity; varicocele recurrence; hydrocele formation; scrotal pain at postoperative days 1, 3, and 7; and other complications. Results: Mean age was 24.2±3.4 years in Group I and 25.1±2.1 years in Group II. Mean pain scores at postoperative 1, 3, and 7 days in Group I were (5.20±1.14, 4.60±0.97, and 3.50±0.97, respectively) significantly higher than those of Group II (0.70±0.82, 0.60±0.84, and 0.10±0.32, respectively). Time to return to normal activity was significantly shorter in Group II (3.7±2.1 days) compared with Group I (6.8±3.4 days) (p=0.028). However, the number of recurrences and hydroceles, as a complication of varicocelectomy, was 2 times higher in Group II (10%) than in Group I (5%). Conclusions: We believe that laparoscopic varicocelectomy is a safe, effective, and minimally invasive procedure. Furthermore, reduced postoperative discomfort and earlier return to normal activity are additional advantages of this method. PMID:23477168

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

Faces scales are commonly used to obtain self-reports of pain intensity from children. Previous research using hypothetical vignettes and pain following venepuncture has found differences in children's pain ratings as a function of the type of faces scale used. The purpose of the present study was to determine whether scales beginning with a smiling rather than neutral "no pain" face would produce higher ratings in the assessment of postoperative pain intensity in children and to compare ratings using different faces scales to those reported with an additional independent measure of pain intensity. Participants were 78 children between the ages of 5 and 13 years undergoing surgery, one of their parents, and their postoperative care nurse. Following surgery, children were asked to provide a rating of their current pain intensity using a set of 5 successively administered faces scales and the Colored Analog Scale (CAS). Parents and nurses provided independent ratings using the same measures. Results showed that parents and nurses rated significantly more pain when using scales with a smiling rather than a neutral "no pain" face. This pattern was not as clear for the children's ratings, although their highest ratings were provided when using a smiling "no pain" faces scale. Children's and nurses' ratings on the CAS were generally more similar to their ratings using scales with neutral "no pain" faces, whereas parents' CAS ratings tended to fall in between ratings provided on the smiling and neutral "no pain" faces scales. Scale preference, age and sex differences in pain ratings, and child-parent-nurse agreement in pain ratings are also examined. Children's and parents' ratings of postoperative pain intensity are influenced by the presence of a smiling "no pain" face at the beginning of faces scales, with such scales producing significantly higher ratings than scales with neutral "no pain" faces. Ratings on the independent CAS measure were more comparable to those

Background: Several measurement tools have been used for assessment of postoperative pain in pediatric patients. Self-report methods have limitations in younger children and parent, nurse or physician assessment can be used as a surrogate measure. These tools should be tested in different cultures as pain can be influenced by sociocultural factors. The objective was to assess the inter-rater agreement on four different behavioral pain assessment scales in our local population. Materials and Methods: This prospective, descriptive, observational study was conducted in Pakistan. American Society of Anesthesiologists I and II children, 3-7 years of age, undergoing elective surgery were enrolled. Four pain assessment scales were used, Children's Hospital of Eastern Ontario Pain Scale (CHEOPS), Toddler Preschool Postoperative Pain Scale (TPPPS), objective pain scale (OPS), and Face, Legs, Activity, Cry, Consolability (FLACC). After 15 and 60 min of arrival in the postanesthesia care unit (PACU), each child evaluated his/her postoperative pain by self-reporting and was also independently assessed by the PACU nurse, PACU anesthetist and the parent. The sensitivity and specificity of the responses of the four pain assessment scales were compared to the response of the child. Results: At 15 min, sensitivity and specificity were >60% for doctors and nurses on FLACC, OPS, and CHEOPS scales and for FLACC and CHEOPS scale for the parents. Parents showed poor agreement on OPS and TPPS. At 60 min, sensitivity was poor on the OPS scale by all three observers. Nurses showed a lower specificity on FLACC tool. Parents had poor specificity on CHEOPS and rate of false negatives was high with TPPS. Conclusions: We recommend the use of FLACC scale for assessment by parents, nurses, and doctors in Pakistani children aged between 3 and 7. PMID:25829906

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

Introduction: The aim of the present study was to compare the effect of two different rotary instruments on postoperative pain in teeth with asymptomatic irreversible pulpitis. Methods and Materials: A total of 78 mandibular first and second molars were divided into two groups (n=39) and their root canal preparation was carried out with either RaCe or ProTaper rotary instruments. All the subjects underwent one-visit root canal treatment and the severity of postoperative pain was evaluated using visual analog scale (VAS) at 4-, 12-, 24-, 48- and 72-h and 1-week intervals. In addition, the need for taking analgesics was recorded. Data were analyzed with the repeated-measures ANOVA and the Mann-Whitney U test was used for two-by-two comparison. Statistical significance was set at 0.05. Results: Comparison of mean pain severity between the two groups at various postoperative intervals did not reveal any significant differences (P=0.10). The difference in amount of analgesics taken by each groups was not statistically significant (P=0.25). Conclusion: There were no significant differences in the postoperative pain reported between the two groups; which indicates the clinical acceptability of both systems. PMID:26843876

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

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.

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.

The experience of pain is frequently observed among children undergoing surgery. Hospitalization and surgery are stressful experiences for those children. The research was conducted to investigate and analyze Turkish nurses' use of nonpharmacological methods to relieve postoperative pain in children. The study was cross-sectional and descriptive. The study took place at 2 hospitals in eastern Turkey. Participants were 143 nurses whose patients had undergone surgical procedures at the 2 hospitals. The researchers used a questionnaire, a checklist of nonpharmacological methods, and a visual analogue scale (VAS) to collect the data. To assess the data, descriptive statistics and the χ² test were used. Of the 143 nurses, 73.4% initially had applied medication when the children had pain. Most of the nurses (58.7%) stated the children generally experienced a middle level of postoperative pain. The most frequent practices that the nurses applied after the children's surgery were (1) "providing verbal encouragement" (90.2%), a cognitive-behavioral method; (2) "a change in the child's position" (85.3%), a physical method; (3) "touch" (82.5%), a method of emotional support; and (4) "ventilation of the room" (79.7%), a regulation of the surroundings. Compared with participants with other educational levels, the cognitive-behavioral methods were the ones most commonly used by the more educated nurses (P < .05): (1) encouraging patients with rewards, (2) helping them think happy thoughts, (3) helping them use their imaginations, (4) providing music, and (5) reading books. Female nurses used the following methods more than the male nurses did (P < .05): (1) providing encouragement with rewards, (2) helping patients with deep breathing, (3) keeping a desired item beside them, (4) changing their positions, and (5) ventilating the room. Undergoing surgery is generally a painful experience for children. Nurses most commonly use cognitive-behavioral methods in the postoperative

Background The aim of this retrospective study was to compare immediate postoperative pain scores and need for rescue analgesia in children who underwent pulpotomies and restorative treatment and those who underwent restorative treatment only, all under general anaesthesia. Methods Ninety patients aged between 3 and 7 years who underwent full mouth dental rehabilitation under general anaesthesia were enrolled in the study and reviewed. The experimental group included patients who were treated with at least one pulpotomy, and the control group was treated with dental fillings only. The Wong-Baker FACES scale was used to evaluate self-reported pain and need for rescue analgesia. The data were analysed using the Kruskal-Wallis test, two sample t-tests, chi-square tests, and Pearson's correlation analysis. Results Ninety percent of the children experienced postoperative pain in varying degrees of severity. Immediate postoperative pain scores in experimental group were found to be significantly higher than in control group (x2 = 24.82, p < 0.01). In the experimental group, 48% of the children needed rescue analgesia, compared with only 13% of the children in the control group (x2 = 13.27, p < 0.05). Conclusion Children who underwent pulpotomy treatment had higher postoperative pain scores and greater need for rescue analgesia than control group who underwent only dental fillings. PMID:28684927

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.

The aim of this study was to describe how parents manage their child's postoperative pain at home following day-case surgery. The incidence of pain, different analgesics used and problems related to administering medications were the main interests of the study. A postal questionnaire was sent to the parents of 275 children who were under 8 years of age and had undergone an ear, nose and throat (ENT) day-case operation. The questionnaire was sent to the parents a week after discharge from hospital. Altogether, the parents of 227 children answered the questionnaire (response rate 83%). The study was divided into two phases (preintervention and postintervention), and incorporated a training program for doctors and nurses between these two phases. The training program aimed to improve the treatment practices of postoperative pain in children. Seventy-eight per cent of the children in the preintervention study and 75% in the postintervention study experienced at least mild pain after discharge. The training program for doctors and nurses affected the home treatment practices of postoperative pain. The proportion of parents treating their children increased from 68% to 80% after the training program (p = 0.028). Many parents faced problems while treating their children; for example, 19% (n = 30) of the children refused to take their medicine, and suppositories were regarded to be an especially unpleasant dosage form. However, no serious adverse effects were reported. We conclude that due to the pain experienced at home by the great majority of children following day-case ENT operations, parents need information on how to manage their child's pain. A training program for doctors and nurses can improve the treatment of children's pain even at home. Since some children dislike suppositories, it would be worth considering the use of small tablets or mixtures instead.

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.

The aim of this study was to determine the types, incidence, and risk factors for early postoperative pulmonary complications in heart transplant recipients. We retrospectively collected data from the records of consecutive heart transplantations from January 2003 to December 2013. A total of 83 patients underwent heart transplantation. The data collected for each case were demographic features, duration of mechanical ventilation, respiratory problems that developed during the intensive care unit (ICU) stay, and early postoperative mortality (<30 d). Of the 72 patients considered, 52 (72.2%) were male. The overall mean age at the time of transplantation was 32.1 ± 16.6 years. Twenty-five patients (34.7%) developed early postoperative respiratory complications. The most frequent problem was pleural effusion (n = 19; 26.4%), followed by atelectasis (n = 6; 8.3%), acute respiratory distress syndrome (n = 5; 6.9%), pulmonary edema (n = 4; 5.6%), and pneumonia (n = 3; 4.2%). Postoperative duration of mechanical ventilation (44.2 ± 59.2 h vs 123.8 ± 190.8 h; P = .005) and the length of postoperative ICU stay (10.1 ± 5.8 h vs 19.8 ± 28.9 h; P = .03) were longer among patients who had respiratory problems. Postoperative length of stay in the hospital (22.3 ± 12.5 d vs 30.3 ± 38.3 d; P = .75) was similar in the 2 groups. The overall mortality rate was 12.5% (n = 9). The patients who had respiratory problems did not show higher mortality than those who did not have respiratory problems (16.0% vs 10.6%; P = .71). Respiratory complications were relatively common in our cohort of heart transplant recipients. However, these complications were mostly self-limiting and did not result in worse mortality.

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

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.

Single dose oral celecoxib for acute postoperative pain in adults

PubMed Central

Derry, Sheena; Moore, R Andrew

2014-01-01

Background This is an update of a review published in The Cochrane Library 2008, Issue 4. Celecoxib is a selective cyclo-oxygenase-2 (COX-2) inhibitor usually prescribed for the relief of chronic pain in osteoarthritis and rheumatoid arthritis. Celecoxib is believed to be associated with fewer upper gastrointestinal adverse effects than conventional non-steroidal anti-inflammatory drugs (NSAIDs). Its effectiveness in acute pain was demonstrated in the earlier reviews. Objectives To assess analgesic efficacy and adverse effects of a single oral dose of celecoxib for moderate to severe postoperative pain. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Database, and ClinicalTrials.gov. The most recent search was to 3 January 2012. Selection criteria We included randomised, double-blind, placebo-controlled trials (RCTs) of adults prescribed any dose of oral celecoxib or placebo for acute postoperative pain. Data collection and analysis Two review authors assessed studies for quality and extracted data. We converted summed pain relief (TOTPAR) or pain intensity difference (SPID) into dichotomous information, yielding the number of participants with at least 50% pain relief over four to six hours, and used this to calculate the relative benefit (RB) and number needed to treat to benefit (NNT) for one patient to achieve at least 50% of maximum pain relief with celecoxib who would not have done so with placebo. We used information on use of rescue medication to calculate the proportion of participants requiring rescue medication and the weighted mean of the median time to use. Main results Eight studies (1380 participants) met the inclusion criteria. We identified five potentially relevant unpublished studies in the most recent searches, but data were not available at this time. The number of included studies therefore remains unchanged. The NNT for celecoxib 200 mg and 400 mg compared with placebo

Laparoscopy is nowadays a well-established surgical method and plays a main role in an ever-increasing range of indications in gynaecology. High-quality studies of surgical techniques are necessary to improve the quality of patient care. The present study aims at evaluating postoperative pain after gynaecological laparoscopy depending on the intraoperative CO 2 pressure. In a prospective, monocentric, randomized single-blind study at the Department of Gynaecology and Obstetrics at the Hannover Medical School, we include patients scheduled for different laparoscopic procedures. Randomization of the intraoperative CO 2 pressure was carried out in six groups. Pain was assessed the day after surgery by the blinded nurse using a visual analogue scale. 550 patients were included in the period from May 2013 to January 2016. The analysis of the per protocol population PPP (n = 360) showed no statistically significant difference between the six intervention groups with regard to mean postoperative pain perception. In direct comparison between two groups, an intraoperative CO 2 pressure of 15 mmHg was associated with a significant higher pain score than a pressure of 12 mmHg. The difference was 7.46 mm on a 10 cm VAS. The results of our study indicate that a CO 2 pressure of 12 versus 15 mmHg can be advantageous. However, the clinical relevance remains unclear due to the low difference in pain. The additional benefit of an even lower pressure of 10 or 8 mmHg cannot be reliably assessed; we found signs of poor visibility conditions in these low pressure groups.

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.

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.

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.

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.

Arthroscopic rotator cuff repair (ARCR) can provide excellent clinical results for patients who fail to respond to conservative management of symptomatic rotator cuff tears. ARCR, however, can be associated with severe postoperative pain and discomfort that requires adequate analgesia. As ARCR continues to shift toward being performed as an outpatient procedure, it is incumbent on physicians and ambulatory surgical centers to provide appropriate pain relief with minimal side effects to ensure rapid recovery and safe discharge. Although intravenous and oral opioids are the cornerstone of pain management after orthopedic procedures, they are associated with drowsiness, nausea, vomiting, and increased length of hospital stay. As health care reimbursements continue to become more intimately focused on quality, patient satisfaction, and minimizing of complications, the need for adequate pain control with minimal complications will continue to be a principal focus for providers and institutions alike. We present a review of alternative modalities for pain relief after ARCR, including cryotherapy, intralesional anesthesia, nerve blockade, indwelling continuous nerve block catheters, and multimodal anesthesia. In choosing among these modalities, physicians should consider patient- and system-based factors to allow the efficient delivery of analgesia that optimizes recovery and improves patient satisfaction.

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.

Preoperative flurbiprofen axetil administration for acute postoperative pain: a meta-analysis of randomized controlled trials.

PubMed

Wang, Ke; Luo, Jun; Zheng, Limin; Luo, Tao

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

Cerebrospinal fluid (CSF) hypovolemia is a common neurosurgical condition, which may be spontaneous or iatrogenic. At our institution, a substantial number of the reported cases of early post-operative CSF hypovolemia were identified to have unintentional or unrecognized post-operative continuous excessive CSF leakage. Cases who presented with post-operative CSF hypovolemia several days after uneventful intracranial surgeries without continuous CSF leakage were rarely reported. A retrospective review of the medical records of these patients was performed to identify those patients who developed early post-operative CSF hypovolemia without the presence of post-operative continuous CSF leakage. A total of 7 patients, 5 of which were males, were identified in this retrospective study. They experienced CSF hypovolemia between days 1 and 7 after emergency or scheduled intracranial surgeries. Ventricular collapse, cisternal effacement and midline shift are the most common radiological observations. With early diagnosis and management, 4 of the patients achieved a Glasgow Outcome Scale (GOS) score of 5, 1 achieved a GOS score of 4 and the remaining 2 had a GOS score of 3. No mortality was noted in this series. Although rare in incidence, early post-operative CSF hypovolemia may occur without the existence of post-operative continuous CSF leakage. When the diagnosis of CSF hypovolemia is reached, factors that may exacerbate CSF compensation should be promptly terminated. Trendelenburg position and sufficient intravenous hydration are practical and effective managements, and CSF hypovolemia may thereby be reversed in a substantial number of patients.

Maintaining Apical Patency Does Not Increase Postoperative Pain in Molars with Necrotic Pulp and Apical Periodontitis: A Randomized Controlled Trial.

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.

It was the aim of this placebo-controlled study to evaluate the analgesic efficacy of the NASAID carprofen and the pure m-agonist levomthadone over a five-day postoperative evaluation period in dogs with fractures of the humerus or the femur (n = 30). Pain and sedation evaluation was carried out with a visual analogues system (VAS) and with the aid of a numerical estimation scale(NRS). The degree of lameness, the pain treshhold, the glucose and cortisol concentration curves as well as the respiration and heart rate and the systolic blood pressure were used as further pain indicators and to identify drug side effects. The levomethadon group displayed the lowest degree of pain on postoperative examination on the first day. On days 2 to 5, the carprofen group showed the lowest degree of pain in comparison to the placebo group. The levomethadon- and the carprofen group showed no statistically proven differences from day 2 on. Due to great variations in the pain scores and comparatively high median pain score especially on the first day of this study, the efficacy of all analgesics evaluated here must be regarded as insufficient in many cases. Only the parameter nociceptive pain treshhold showed a little, the degree of lameness, the glucose and cortisol levels showed no close correlation to the VAS and NRS pain scores and were therefore of little usefulness as postoperative pain indicators. No relevant clinical side effects caused by the used analgesics were detected in the kidney, the liver, the gastrointestinal tract and the circulatory system in this study. Rather, traumatically induced elevation of enzyme levels improves or normalised until the 5th day of the study. In addition, no negative effect on wound healing was noted, especially for carprofen. Therefore, the evaluated analgesics seems to be adequate for postoperative pain therapy also in fracture patients (trauma patients). However, the efficacy of all analgesics evaluated here must be regarded as

To measure the diagnostic value of the Numeric Rating Scale by comparing it to a Verbal Rating Scale in older patients. Pain management in older patients is an important challenge because of their greater susceptibility to adverse effects of analgesics. Nurses play an important role in applying guidelines for postoperative pain treatment. However, effective pain management is dependent upon valid and reliable pain assessment. Cross-sectional study. In total, 2674 older patients scored their postoperative pain on an 11-point numeric rating scale (NRS) and an adjective scale (VRS) including no pain, little pain, painful but bearable, considerable pain and terrible pain. The diagnostic value of different NRS cut-off values for administering analgesics is determined by an ROC curve. Sensitivity of NRS > 3 for 'unbearable' pain in older patients was 72% with a specificity of 97·2%. With a cut-off point NRS > 4, sensitivity increased to 83%, while specificity was 96·7%. With a cut-off point NRS > 5, sensitivity was 94%, while specificity was 85%. A high proportion (75%) of older old patients (≥ 75 years) with 'painful but bearable' considers NRS 4, 5 and 6 to this VRS category. Using an NRS cut-off point > 3 or > 4, a large group of older patients with 'bearable' pain would incorrectly classified as 'unbearable'. When we make the assumption that bearable pain means no wish for additional analgesics, this misclassification might result in overtreatment with analgesics, while 3% would be undertreated. With NRS cut-off point > 5, 6% have a risk of overtreatment and 15% of undertreatment. Nurses should not rely solely on the NRS score in determining pain treatment; they need to communicate with older patients about their pain, the need for analgesics and eventual misconceptions about analgesics. © 2012 Blackwell Publishing Ltd.

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.

The aim of this study was to evaluate pain management in paediatric surgery at Sylvanus Olympio University Teaching Hospital, Lome. A prospective descriptive study was conducted in the Department of Anaesthesiology and Intensive Care at Sylvanus Olympio teaching hospital from 1 January to 30 June 2012. Data collected include: demography, type of surgery, American Society of Anaesthesiologists (ASA) classification, anaesthetic protocol, analgesia technique, post-operative complications and cost of analgesia. The study includes 106 post-operative children. Abdominal surgery was performed in 41.5% and orthopaedic surgery in 31.1%. A total of 75% of patients were classified ASA 1. General anaesthesia (GA) was performed in 88%. Anaesthetists supervised post-operative care in 21.7% cases. Multimodal analgesia was used in every case and 12% of patients received a regional block. The most frequently unwanted effects of analgesics used were nausea and/or vomiting in 12.3%. At H24, child under 7 years have more pain assessment than those from 7 to 15 years (46% vs 24%) and this difference was statistically significant (chi-square = 4.7598; P = 0.0291 < 0.05). The average cost of peri-operative analgesia under loco regional analgesia (LRA) versus GA during the first 48 h post-operative was US $23 versus $46. Our study showed that post-operative pain management in paediatric surgery is often not well controlled and paediatric loco regional analgesia technique is under practiced in sub Saharan Africa.

To minimize acute postoperative pain, a new formulation of slowly released bupivacaine was developed. Bupivacaine was microencapsulated at 60% (wt/wt) in poly-lactide-co-glycolide polymers and characterized for physicochemical properties and bupivacaine release kinetics. This formulation was injected around the rat sciatic nerve to produce an antinociceptive effect to toe pinch. Mechanical hyperalgesia following lateral plantar paw incision in rats was assessed for 7 to 14 days when the bupivacaine slow-release formulation was placed at the ipsilateral sciatic nerve and compared with the hyperalgesia that developed with various controls. Bupivacaine was released in vitro at a relatively constant rate over a period of ≈ 72 to 96 hours. Complete antinociception, shown as no response to toe pinch, lasted for 23 ± 7 hours, with a half-recovery time of 42 ± 8 hours after sciatic nerve injection of 0.4 mL of the microspheres delivering 34 mg of bupivacaine. Solutions of 0.5% (wt/vol) bupivacaine-HCl (0.1 mL) produced complete antinociception for less than 2 hours and recovery half-times of 2 hours. Postincisional mechanical hyperalgesia, shown by increased withdrawal responses to von Frey filaments, was absent for 24 hours and was lower than control for 96 hours, when the sciatic nerve was blocked by bupivacaine microspheres, whereas the 0.5% bupivacaine solution reduced postincisional pain for only 4 hours. Corresponding to its far greater functional blocking time, the microsphere-bupivacaine formulation was able to significantly reduce postoperative pain below control levels for up to 4 days. These findings of several days of postoperative pain relief, for an injectable formulation containing a single active agent, present an improved and potentially promising therapy to prevent acute pain after surgery.

Although the laparoscopic approach reduces pain associated with abdominal surgery, postoperative pain remains a problem. Ultrasound-guided rectus sheath block and transversus abdominis plane block have become increasingly popular means of providing analgesia for laparoscopic surgery. Ninety patients were enrolled in this study. A laparoscopic puncture needle was inserted via the port, and levobupivacaine was injected into the correct plane through the peritoneum. The patients' postoperative pain intensity was assessed using a numeric rating scale. The effects of laparoscopic nerve block versus percutaneous anesthesia were compared. This novel form of transperitoneal anesthesia did not jeopardize completion of the operative procedures. The percutaneous approach required more time for performance of the procedure than the transperitoneal technique. This new analgesia technique can become an optional postoperative treatment regimen for various laparoscopic abdominal surgeries. What we mainly want to suggest is that the transperitoneal approach has the advantage of a higher completion rate. A percutaneous technique is sometimes difficult with patients who have severe obesity and/or coagulation disorders. Additional studies are required to evaluate its benefits. Copyright © 2017.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are often used to treat inflammation, pain, and fever, but no criterion standard exists for the management of postoperative pain following spinal surgery. In the present study, we compared the analgesic efficacy of loxoprofen sodium (loxoprofen) and celecoxib for the management of postoperative pain following spinal surgery. One-hundred forty-one patients (mean age 62.2 years) were randomly assigned to two groups before spinal surgery: a loxoprofen group (n = 73, 180 mg/day) and a celecoxib group (n = 68, 200 mg/day). The drugs were administered from 1 day until 7 days after surgery. A numeric rating scale (NRS) was used to evaluate pain at nine predefined times every day and the findings were compared between the two groups. Laboratory data and adverse events were also recorded. There was no significant difference in the maximum and mean NRS scores on each day between loxoprofen and celecoxib, suggesting a comparable analgesic effect for these two NSAIDs. Greater improvement in the NRS score between preadministration (baseline) and 30 min or 2 h after administration was obtained for loxoprofen. This tendency was shown for both slight (NRS score <5 at baseline) and severe pain (NRS score ≥ 5 at baseline). Loxoprofen was discontinued in one patient on day 4 because of renal dysfunction. Celecoxib was discontinued in one patient on day 2 at the patient's request. Both loxoprofen sodium and celecoxib were well tolerated for the relief of acute postoperative pain after spinal surgery. A single administration of loxoprofen showed superior and rapid effectiveness compared with celecoxib for both slight and severe postoperative pain.

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.

Acute postoperative pain causes physiological deficits and slows recovery. Reduction of such pain by local anesthetics that are delivered for several days postoperatively is a desirable clinical objective, which is approached by a new formulation and applied in animal studies reported here. We subcutaneously injected a new formulation of poly-lactic-co-glycolic acid polymer microspheres, which provides steady drug release for 96+ hours into rats at the dorsal region 2 hours before surgery. A single 1.2-cm-long skin incision was followed by blunt dissection of skin away from the underlying fascia, and closed by 2 sutures, followed by 14 days of testing. Microspheres containing 5, 10, 20, and 40 mg bupivacaine were injected locally 2 hours before surgery; bupivacaine-free microspheres were the vehicle control, and bupivacaine HCl solution (0.5%), the positive control. Mechanical sensitivity was determined by the frequency of local muscle contractions to repeated pokes with nylon monofilaments (von Frey hairs) exerting 4 and 15 g forces, testing, respectively, allodynia and hyperalgesia, and by pinprick. Injection of bupivacaine microspheres (40 mg drug) into intact skin reduced responses to 15 g von Frey hairs for 6 hours and to pinprick for 36 hours. Respective reductions from bupivacaine HCl lasted for 3 and 2 hours. Skin incision and dissection alone caused mechanical allodynia and hyperalgesia for 14 days. Microspheres containing 20 or 40 mg bupivacaine suppressed postoperative hypersensitivity for up to 3 days, reduced integrated allodynia (area under curve of response versus time) over postoperative days 1 to 5 by 51% ± 20% (mean ± SE) and 78% ± 12%, and reduced integrated hyperalgesia by 55% ± 13% and 64% ± 11%, for the respective doses. Five and ten milligrams bupivacaine in microspheres and the 0.5% bupivacaine solution were ineffective in reducing postoperative hypersensitivity, as were 40 mg bupivacaine microspheres injected contralateral to the

Regional analgesic techniques are commonly used in pediatric urology. Ultrasound guided transversus abdominis plane block has recently gained popularity. However, there is a paucity of information supporting a benefit over regional field infiltration. We present a parallel group, randomized, controlled trial evaluating ultrasound guided transversus abdominis plane block superiority over surgeon delivered regional field infiltration for children undergoing open pyeloplasty at a tertiary referral center. Following ethics board approval and registration, children 0 to 6 years old were recruited and randomized to undergo perioperative transversus abdominis plane block or regional field infiltration for early post-pyeloplasty pain control. General anesthetic delivery, surgical technique and postoperative analgesics were standardized. A blinded assessor regularly captured pain scores in the recovery room using the FLACC (Face, Legs, Activity, Cry, Consolability) scale. The primary outcome was the need for rescue morphine administration based on a FLACC score of 3 or higher. Two pediatric urologists performed 57 pyeloplasties during a 2.5-year period, enrolling 32 children (16 in each group, balanced for age and weight). There were statistically significant differences in the number of children requiring rescue morphine administration (13 of 16 receiving transversus abdominis plane block and 6 of 16 receiving regional field infiltration, p = 0.011), mean ± SD total morphine consumption (0.066 ± 0.051 vs 0.028 ± 0.040 mg/kg, p = 0.021) and mean ± SD pain scores (5 ± 5 vs 2 ± 3, p = 0.043) in the recovery room, in favor of surgeon administered regional field infiltration. No local anesthetic specific adverse events were noted. Ultrasound guided transversus abdominis plane block is not superior to regional field infiltration with bupivacaine as a strategy to minimize early opioid requirements following open pyeloplasty in children. Instead, our data suggest that

Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological analgesic method used to control different types of pain. The aim of this study was to evaluate the effects of preoperative TENS on post inguinal hernia repair pain. This randomized, double-blind, placebo-controlled clinical trial was performed on 66 male patients with unilateral inguinal hernias who were admitted to the Shahid Beheshti hospital in Kashan, Iran, from April to October 2014. Participants were selected using a convenience sampling method and were assigned to intervention (n = 33) and control (n = 33) groups using permuted-block randomization. Patients in the intervention group were treated with TENS 1 hour before surgery, while the placebo was administered to patients in the control group. All of the patients underwent inguinal hernia repair by the Lichtenstein method, and pain intensity was evaluated at 2, 4, 6, and 12 hours after surgery using a visual analogue scale. Additionally, the amounts of analgesic administered by pump were calculated and compared between the two groups. The mean estimated postoperative pain intensity was 6.21 ± 1.63 in the intervention group and 5.45 ± 1.82 in the control group (P = 0.08). In the intervention group pain intensity at 2 and 4 hours after surgery were 3.54 ± 1.48 and 5.12 ± 1.41 (P < 0.001), respectively. In the control group these values were 4.0±1.5 and 4.76 ± 1.39 (P = 0.04), respectively. No significant differences were observed in mean pain intensities at 6 and 12 hours. TENS can reduce postoperative pain in the early hours after inguinal hernia repair surgery.

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.

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.

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.

The experience of pain associated with surgery has been a challenge for health care professionals for many years, and culture is said to influence pain. This study focused on patients' experiences of postoperative pain (POP) and factors that affect POP. The study employed qualitative ethnographic principles. Data were collected through individual face-to-face interviews. Data were saturated after analyzing data from 13 patients from two hospitals in Ghana. Themes that emerged were the subjective nature of pain, which described pain dimensions and communication; psycho-sociocultural factors, such as personal inclinations and sociocultural background; and health system factors, such as personnel attitudes and health financing. Health professionals need to understand the sociocultural effects of pain in order to give effective care. The study highlighted the need for patient education and the importance that health care professionals understand context-specific factors that influence POP management. © The Author(s) 2014.

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

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.

University medical center. 56 ASA status I and II women scheduled for abdominal hysterectomy were randomly assigned to one of three treatment groups. Group 1 (control) received no local anesthetic infiltration. Group 2 received subcutaneous infiltration with 40 ml of bupivacaine 0.5% (pH 6.9) 15 minutes prior to incision. Group 3 received wound infiltration with a similar solution at the end of surgery. Anesthesia was induced with thiopental 3.0 mg/kg i.v., droperidol 50 micrograms/kg i.v., and sufentanil 0.5 microgram/kg i.v. and maintained with nitrous oxide 67% in oxygen and sufentanil 0.1 microgram/kg IV boluses as required. Postoperative pain was treated with morphine via a patient-controlled analgesia delivery system for 24 hours, followed by oral hydrocodone for 3 days. The opioid consumption was recorded for 4 days postoperatively. Pain scores were measured at 4 to 8-hour intervals using 100 mm visual analog scales. There was no difference in either the opioid analgesic requirements or the pain scores between the three study groups. Wound infiltration, either preincision or postincision, had no clinically significant effect on the pain scores or analgesic requirements following abdominal hysterectomy.

Arthroscopic knee surgeries have a painful postoperative course, which often necessitates acute pain management. Among different analgesia techniques, Intra-articular injection is the technique of choice for many pain specialists, based on its confined effect to the surgical site (knee), lack of systemic effects and promotion of safe early ambulation. The aim of this study was to compare analgesic effects of intra-articular meperidine, bupivacaine 0.5% or their combination after knee arthroscopic surgery. Sixty ASA class I-II patients' candidates for arthroscopy knee surgery enrolled in a randomized double blind study to receive either 20 mL of bupivacaine 0.5%; 100 mg meperidine (diluted in normal saline) or bupivacaine 0.5% along with 100 mg meperidine. A written informed consent was obtained from all patients. Postoperative analgesia duration, VAS at 2, 6, 12 and 24 hours, the first analgesic request time, total fentanyl consumption in first 24 hours, patients' satisfaction and adverse effects were recorded. The bupivacaine-meperidine group had better duration of postoperative analgesia (P = 0.001), latter first analgesic request (P ≤ 0.001), lower total fentanyl consumption in first 24 hours after the operation (P = 0.001), less mean VAS at 2 hours (P = 0.001) and more patients' overall satisfaction (P = 0.01) compared with each medication alone. VAS at 6, 12 and 24 postoperative hours were not different between the groups of study. No adverse effects were observed. Although postoperative intra-articular meperidine is a better alternative for bupivacaine, their combination could improve their analgesic effects compared with each other alone.

Background: Visual analog scales (VAS) and numeric analog scales (NAS) are used to assess post-operative pain, but few studies indicate their usefulness in rural illiterate population in India. Aims: This study was designed to 1) Compare the impact of literacy on the ability to indicate pain rating on VAS and NAS in post-operative rural patients. 2) Assess the level of agreement between the pain scales. Setting and Design: Cross sectional, hospital based study. Methods: Informed consent was obtained from patients prior to undergoing surgical procedures in a teaching hospital. Post surgery, patients who were conscious and coherent, were asked to rate pain on both VAS and NAS. The pain ratings were obtained within 24 hours of surgery and within 5 minutes of each other. Statistical Methods: Percentages, chi square test, regression analysis. Results: A total of 105 patients participated in the study. 43 (41%) of the sample was illiterate. 82 (78.1%) were able to rate pain on VAS while 81 (77.1%) were able to rate pain on NAS. There was no significant association between pain ratings and type of surgery, duration of surgery and nature of anaesthesia. In multivariate analysis, age, sex and literacy had no significant association with the ability to rate pain on VAS (P value 0.652, 0.967, 0.328 respectively). Similarly, no significant association was obtained between age, sex and literacy and ability to rate pain on NAS (P value 0.713, 0.405, 0.875 respectively). Correlation coefficient between the scales was 0.693. Conclusion: VAS and NAS can be used interchangeably in Indian rural population as post-operative pain assessment tools irrespective of literacy status. PMID:23325940

Introduction Laparoscopic Cholecystectomy (LC) is the most frequently performed elective daycare surgery and provision of postoperative pain relief is of importance. After laparoscopic cholecystectomy shoulder and abdominal pain causes considerable distress. Visceral pain during coughing, respiration and mobilization increases morbidity, hospital stay and costs. Aim To compare the analgesic efficacy of intraperitoneally instilled equipotent concentrations of bupivacaine and ropivacaine versus placebo in relieving postoperative pain after laparoscopic cholecystectomy when used as a part of multimodal analgesia. Materials and Methods In this randomised, prospective, double blind, placebo controlled study, 90 ASA Class I or II patients were randomly divided into three groups of 30 each. Group S received intraperitoneal infiltration with 35 ml of 0.9% normal saline, Group B with 35 ml of 0.25% bupivacaine and Group R with 35 ml of 0.375% ropivacaine. All groups received standard general endotracheal anaesthesia and analgesia with IV paracetamol 15 mg/kg and diclofenac 1.5 mg/kg. Numerical Rating Scale (NRS) score of analgesia at rest and on cough/movement, duration of analgesia, haemodynamic parameters, need for a rescue analgesic (IV tramadol 1 mg/kg) was recorded and adverse effects of procedure and drugs if any were monitored. Data was analysed with SPSS statistical software version 21.0. One way ANOVA or the Kruskal–Wallis test was used to compare continuous data across all three groups as appropriate. Subsequent analysis of continuous data between two groups was achieved by Tukey’s post hoc test. Significance was accepted as p<0.05. Results The mean NRS was <5 till only four hours in Group S, till eight hours in Group B and till 16 hours in Group R. The duration of analgesia was 13.47±1.38 hours in Group R, 7.93±1.44 hours in Group B and 4.47±0.86 hours in Group S.

The effect of complementary therapies on post-operative pain control in ambulatory knee surgery: a systematic review.

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.

Surgical and medical procedures, mainly those associated with nerve injuries, may lead to chronic persistent pain. Currently, one cannot predict which patients undergoing such procedures are 'at risk' to develop chronic pain. We hypothesized that the endogenous analgesia system is key to determining the pattern of handling noxious events, and therefore testing diffuse noxious inhibitory control (DNIC) will predict susceptibility to develop chronic post-thoracotomy pain (CPTP). Pre-operative psychophysical tests, including DNIC assessment (pain reduction during exposure to another noxious stimulus at remote body area), were conducted in 62 patients, who were followed 29.0+/-16.9 weeks after thoracotomy. Logistic regression revealed that pre-operatively assessed DNIC efficiency and acute post-operative pain intensity were two independent predictors for CPTP. Efficient DNIC predicted lower risk of CPTP, with OR 0.52 (0.33-0.77 95% CI, p=0.0024), i.e., a 10-point numerical pain scale (NPS) reduction halves the chance to develop chronic pain. Higher acute pain intensity indicated OR of 1.80 (1.28-2.77, p=0.0024) predicting nearly a double chance to develop chronic pain for each 10-point increase. The other psychophysical measures, pain thresholds and supra-threshold pain magnitudes, did not predict CPTP. For prediction of acute post-operative pain intensity, DNIC efficiency was not found significant. Effectiveness of the endogenous analgesia system obtained at a pain-free state, therefore, seems to reflect the individual's ability to tackle noxious events, identifying patients 'at risk' to develop post-intervention chronic pain. Applying this diagnostic approach before procedures that might generate pain may allow individually tailored pain prevention and management, which may substantially reduce suffering.

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.

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.

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

Recent studies have identified Propionibacterium acnes as the causal organism in an increasing number of postoperative shoulder infections. Most reports have found a high rate of P acnes infection after open surgery, particularly shoulder arthroplasty. However, there are limited data regarding P acnes infections after shoulder arthroscopy. We prospectively collected data on all shoulder arthroscopies performed by the senior author from January 1, 2009, until April 1, 2013. Cultures were taken in all revision shoulder arthroscopy cases performed for pain, stiffness, or weakness. In addition, 2 cultures were taken from each of a cohort of 32 primary shoulder arthroscopy cases without concern for infection to determine the false-positive rate. A total of 1,591 shoulder arthroscopies were performed during this period, 68 (4.3%) of which were revision procedures performed for pain, stiffness, or weakness. A total of 20 revision arthroscopies (29.4%) had positive culture findings, and 16 (23.5%) were positive for P acnes. In the control group, 1 patient (3.2%) had P acnes growth. The rate of P acnes infection in patients undergoing revision shoulder arthroscopy is higher than previously published and should be considered in cases characterized by refractory postoperative pain and stiffness.

Common risk factors for postoperative pain following the extraction of wisdom teeth

PubMed Central

2015-01-01

The extraction of third molars is a common task carried out at dental/surgery clinics. Postoperative pain is one of the two most common complications of this surgery, along with dry socket. Knowledge of the frequent risk factors of this complication is useful in determining high-risk patients, planning treatment, and preparing the patients mentally. Since the risk factors for postoperative pain have never been summarized before while the risk factors for dry socket have been highly debated, this report summarizes the literature regarding the common predictors of postextraction pain. Except for surgical difficulty and the surgeon's experience, the influences of other risk factors (age, gender and oral contraceptive use) were rather inconclusive. The case of a female gender or oral contraceptive effect might mainly be associated with estrogen levels (when it comes to dry socket), which can differ considerably from case to case. Improvement in and unification of statistical and diagnostic methods seem necessary. In addition, each risk factor was actually a combination of various independent variables, which should instead be targeted in more comprehensive studies. PMID:25922816

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.

Tonsillectomy is one of the oldest and most commonly performed surgical procedure in otolaryngology. Postoperative pain management is still an unsolved problem. In this study, our aim is to demonstrate the efficacy of intranasal ketamine and intranasal fentanyl for postoperative pain relief after tonsillectomy in children. This randomized-controlled study was conducted to evaluate the effects of intranasal ketamine and intranasal fentanyl in children undergoing tonsillectomy. Tonsillectomy performed in 63 children were randomized into three groups. Group I received: Intravenous paracetamol (10 mg/kg), Group II received intranasal ketamine (1.5 mg/kg ketamine), Group III received intranasal fentanyl (1.5 mcg/kg). The Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) and Wilson sedation scale scores were recorded at 15, 30, 60 min, 2 h, 6hr, 12 h and 24 h postoperatively. Patients were interviewed on the day after surgery to assess the postoperative pain, nightmares, hallucinations, nausea, vomiting and bleeding. Intranasal ketamine and intranasal fentanyl provided significantly stronger analgesic affects compared to intravenous paracetamol administration at postoperative 15, 30, 60 min and at 2, 6, 12 and 24 h in CHEOPS (p < 0.05). Sedative effects were observed in three patients in the intranasal ketamine administration group. No such sedative effect was seen in the groups that received intranasal fentanyl and intravenous paracetamol in Wilson Sedation Scale (p < 0.05). Cognitive impairment, constipation, nausea, vomiting and bleeding were not observed in any of the groups. This study showed that either intranasal ketamine and intranasal fentanyl were more effective than paracetamol for postoperative analgesia after pediatric tonsillectomy. Sedative effects were observed in three patients with the group of intranasal ketamine. There was no significant difference in the efficacy of IN Ketamine and IN Fentanyl for post-tonsillectomy pain

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.

Total hip and knee replacements are common surgeries, and an optimal pain treatment is essential for early rehabilitation. Since data from randomized controlled trails on the use of regional anesthesia in joint replacements of the lower extremities are conflicting, we analyzed the international PAIN OUT registry for comparison of regional anesthesia vs. general anesthesia regarding pain and morphine consumption on the first postoperative day. International Classification of Diseases-9 (ICD-9) codes were used to identify 2,346 cases for knee and 2,315 for hip arthroplasty between 2010 and 2016 from the PAIN OUT registry. Those were grouped according to anesthesia provided (general, regional, and a combination of both). At the first day after surgery, pain levels and opioid consumption was compared. Adjusted odds ratios (aOR [95% CI]) were calculated with logistic regression and propensity matching was used as a sensitivity analysis. After adjustment for confounders, regional anesthesia was associated with reduced opioid consumption (0.20 [0.13-0.30], p<0.001) and less pain (0.53 [0.36-0.78], p=0.001) than general anesthesia in knee surgery. In hip surgery, regional anesthesia was only associated with reduced opioid consumption (0.17 [0.11-0.26], p<0.001), whereas pain was comparable (1.23 [0.94-1.61], p=0.1). Results from a propensity-matched sensitivity analysis were similar. In total knee arthroplasty, regional anesthesia was associated with less pain and lower opioid consumption. In total hip arthroplasty, regional anesthesia was associated with a lower opioid consumption, however not with reduced pain levels. This article is protected by copyright. All rights reserved.

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.

Surgical trauma at the temporalis muscle is a potential cause of post-craniotomy headache and temporomandibular disorders (TMD). The aim of this study was to evaluate the prevalence of pain, masticatory dysfunction and trigeminal somatosensory abnormalities in patients who acquired aneurysms following pterional craniotomy. Fifteen patients were evaluated before and after the surgical procedure by a trained dentist. The evaluation consisted of the (1) research diagnostic criteria for TMD, (2) a standardized orofacial pain questionnaire and (3) a systematic protocol for quantitative sensory testing (QST) for the trigeminal nerve. After pterional craniotomy, 80% of the subjects, 12 patients, developed orofacial pain triggered by mandibular function. The pain intensity was measured by using the visual analog scale (VAS), and the mean pain intensity was 3.7. The prevalence of masticatory dysfunction was 86.7%, and there was a significant reduction of the maximum mouth opening. The sensory evaluation showed tactile and thermal hypoesthesia in the area of pterional access in all patients. There was a high frequency of temporomandibular dysfunction, postoperative orofacial pain and trigeminal sensory abnormalities. These findings can help to understand several abnormalities that can contribute to postoperative headache or orofacial pain complaints after pterional surgeries.

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.

AIM: To determine the efficacy of perioperative parecoxib injection on postoperative pain relief after laparoscopic cholecystectomy. METHODS: A prospective, double-blind, randomized, placebo-controlled study was conducted on 70 patients who underwent elective laparoscopic cholecystectomy under general anesthesia at Siriraj Hospital, Bangkok, from January 2006 to December 2007. Patients were randomized to receive either 20 mg parecoxib infusion 30 min before induction of anesthesia and at 12 h after the first dose (treatment group), or normal saline infusion, in the same schedule, as a placebo (control group). The degree of the postoperative pain was assessed every 3 h in the first 24 h after surgery, and then every 12 h the following day, using a visual analog scale. The consumption of analgesics was also recorded. RESULTS: There were 40 patients in the treatment group, and 30 patients in the control group. The pain scores at each time point, and analgesic consumption did not differ between the two groups. However, there were fewer patients in the treatment group than placebo group who required opioid infusion within the first 24 h (60% vs 37%, P = 0.053). CONCLUSION: Perioperative administration of parecoxib provided no significant effect on postoperative pain relief after laparoscopic cholecystectomy. However, preoperative infusion 20 mg parecoxib could significantly reduce the postoperative opioid consumption. PMID:19399934

Background Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological analgesic method used to control different types of pain. Objectives The aim of this study was to evaluate the effects of preoperative TENS on post inguinal hernia repair pain. Patients and Methods This randomized, double-blind, placebo-controlled clinical trial was performed on 66 male patients with unilateral inguinal hernias who were admitted to the Shahid Beheshti hospital in Kashan, Iran, from April to October 2014. Participants were selected using a convenience sampling method and were assigned to intervention (n = 33) and control (n = 33) groups using permuted-block randomization. Patients in the intervention group were treated with TENS 1 hour before surgery, while the placebo was administered to patients in the control group. All of the patients underwent inguinal hernia repair by the Lichtenstein method, and pain intensity was evaluated at 2, 4, 6, and 12 hours after surgery using a visual analogue scale. Additionally, the amounts of analgesic administered by pump were calculated and compared between the two groups. Results The mean estimated postoperative pain intensity was 6.21 ± 1.63 in the intervention group and 5.45 ± 1.82 in the control group (P = 0.08). In the intervention group pain intensity at 2 and 4 hours after surgery were 3.54 ± 1.48 and 5.12 ± 1.41 (P < 0.001), respectively. In the control group these values were 4.0±1.5 and 4.76 ± 1.39 (P = 0.04), respectively. No significant differences were observed in mean pain intensities at 6 and 12 hours. Conclusions TENS can reduce postoperative pain in the early hours after inguinal hernia repair surgery. PMID:27275401

  To compare the effects of single doses of three oral medications on postoperative pain following instrumentation of root canals in teeth with irreversible pulpitis.   In this double-blind clinical trial, 100 patients who had anterior or premolar teeth with irreversible pulpitis without any signs and symptoms of acute or chronic apical periodontitis and moderate to severe pain were divided by balanced block random allocation into four groups of 25 each, a control group receiving a placebo medication, and three experimental groups receiving a single dose of either Tramadol (100 mg), Novafen (325 mg of paracetamol, 200 mg ibuprofen and 40 mg caffeine anhydrous) or Naproxen (500 mg) immediately after the first appointment where the pulp was removed, and the canals were fully prepared. The intensity of pain was scored based on 10-point VAS before and after treatment for up to 24 h postoperatively. Data were submitted to repeated analysis of variance.   At the 6, 12 and 24 h postoperative intervals after drug administration, the intensity of pain was significantly lower in the experimental groups than in the placebo group (P < 0.01). Tramadol was significantly less effective (P < 0.05) than Naproxen, and Novafen that were similar to each other (P > 0.05).   A single oral dose of Naproxen, Novafen and Tramadol taken immediately after treatment reduced postoperative pain following pulpectomy and root canal preparation of teeth with irreversible pulpitis. © 2011 International Endodontic Journal.

Postoperative pain is a complex physiological response to disease and tissue injury. Moderate-to-severe pain typically occurs within 48 h after surgery. Amino amide local anesthetics are widely applied to manage postoperative pain, and they have high efficacy, a low risk for addiction and limited side effects. However, these anesthetics also have short half-lives, often necessitating continuous injection to obtain satisfactory pain relief. In the current work, we used a poly(lactic-co-glycolic acid) (PLGA)-polyethylene glycol (PEG)-PLGA (PLGA-PEG-PLGA) temperature-sensitive gel to deliver a local anesthetic, ropivacaine hydrochloride (RP), to prolong its analgesic effect. We investigated the influence of polymer and drug concentration on gelation temperature and the in vitro drug release rate from the temperature-sensitive gel. RP-loaded PLGA-PEG-PLGA solution is a liquid at room temperature and forms a gel at temperatures slightly lower than body temperature. With regard to the gel's drug release rate, 37.5, 51.3 and 72.6% of RP was released at 12, 24 and 48 h, respectively. This in vitro drug release profile conformed to the Higuchi equation. To assess pain control efficacy when using the gel, we evaluated the mechanical paw withdrawal reflex threshold, thermal pain threshold and incision cumulative pain scores in a rat incisional model. The results showed that the anti-pain effect of a single injection of RP-loaded gel at the incision site lasted for 48 h, which is significantly longer than the effect produced by injection of RP solution alone. The use of RP-loaded thermosensitive gels could provide a promising method for managing postoperative pain.

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. In this study, the effect of aromatherapy using Lavender (Lavandula) essential oil on cesarean postoperative pain was assessed. 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. 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). 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.

To study postoperative pain relief in major gynaecological surgery by perioperative parecoxib administration in Thammasat University Hospital. This double-blind randomized controlled clinical trial was conducted in Thammasat University Hospital, Pathumthani, Thailand from October 2013 to May 2014. One hundred and twenty patients who underwent elective gynaecological surgery were randomized assigned to study and control groups. Study group (n = 60) received 40 mg parecoxib and control group (n = 60) received placebo at 1 hour before surgery. The postoperative visual analog scale (VAS) at 3, 6, 12 and 24 hours, frequency of meperidine consumption in 24 hours and side effects of parecoxib were recorded. VAS of study group after operation at 3, 6, 12 and 24 hours was significantly lower than control group. Meperidine consumption in placebo group was significantly higher than study group (27.50 ± 19.36 and 48.75 ± 28.15 mg, respectively; p < 0.001). There was no side effect from parecoxib in this study. Intravenous postoperativeparecoxib injection could relief pain and reduced meperidine consumption. Parecoxib could be safely used in gynaecological surgery for postoperative pain relief

Objectives Transcutaneous electrical nerve stimulation has been used to control post-thoracotomy pain, with conflicting results. We aimed to assess its efficacy on post-thoracotomy pain and early complications. Methods Between January 2012 and December 2014, 87 patients underwent a standard posterolateral thoracotomy and were randomized in 2 groups: group T was 43 patients who had transcutaneous electrical nerve stimulation and group C was 44 patients who had placebo stimulation with an inoperative device. Pain score was measured using a visual analogue scale ranging from 0 to 10. The frequency of the device was set at 100 Hz and pulse width at 100 ms. Results There were no statistically significant differences in the demographic characteristics of the 2 groups, and there was no difference in the duration of hospitalization (4.74 ± 1.6 vs. 5.23 ± 1.5 days; p = 0.06). Postoperative pain scores of the two groups showed that on postoperative day 0, 1, and 2, the mean pain scores of group T were significantly lower ( p = 0.001, p < 0.001, and p = 0.003). There were no significant differences in early complications or surgical technique. Conclusion We concluded that electrical stimulation is a safe and effective adjunctive therapy for acute post-thoracotomy pain control. However, it does not affect the duration of hospitalization or early pulmonary complications.

To measure the effect of seeing a photograph of the pelvic findings at laparoscopy. Two university teaching hospitals. A randomised-controlled trial. Two hundred thirty-three women undergoing diagnostic laparoscopy for the investigation of chronic pelvic pain. At operation a Polaroid print was taken of the pelvis. If this was of satisfactory quality, the patient was randomly allocated to either see, or not see, the print during the postoperative consultation. Pain severity and pain belief scores at 3 and 6 months. By intention to treat. Postoperative consultations with photographs did not improve immediate understanding and satisfaction with the consultation. In addition, compared to controls, both patients and doctors did not perceive particular benefit for communication from the photograph. There was a consistent trend to more pain in the photographic reinforcement group and more negative pain beliefs. At 3 months, the average within person differences showed some benefit in visual analogue pain scores, McGill affect scores, 'permanence' and 'self-blame' scores. These benefits were not statistically significant. At 6 months, there was a consistent pattern of benefit from pain severity and pain beliefs, again these benefits were not statistically significant. No clear benefits result from showing patients photographs of their pelvis.

To investigate the efficacy of single injection femoral nerve block (FNB) on the independence level in functional activities in the early postoperative period in patients with total knee arthroplasty (TKA). We conducted this prospective, randomized, blinded trial in the Department of Orthopedics and Traumatology, Hacettepe University Hospital Ankara, Turkey, between June 2003 and April 2004. Twenty-three patients scheduled for elective TKA were randomly divided into 3 groups. Group I received preemptive single injection FNB, group II received postoperative single injection FNB, and group III served as a control group. Intravenous morphine patient controlled analgesia (PCA) was used following surgery in all groups. Morphine dose and pain score defined by the visual analog scale (VAS) were recorded postoperatively at the 15th minute, 30th minute, 1st, 4th, 6th, 12th, 24th, and 48th hours. A standard rehabilitation protocol was applied for all patients. The independence level in functional activities was assessed during the first 2 postoperative days and at discharge with the Iowa Level of Assistance Scale (ILAS) and the Iowa Ambulation Speed Scale (IASS). Physical therapists that enrolled in the study were blinded to the groups. Pain scores were significantly different between the groups (p<0.05). The preemptive and postoperative FNB group`s VAS scores were both significantly lower than the control group (p<0.05). However, there was no significant difference in VAS scores between preemptive and postoperative FNB groups (p>0.05). There was no statistically significant difference between the groups in any of the functional scores in the first 2 postoperative days, and at discharge (p>0.05). Single injection FNB provided effective analgesia in patients undergoing TKA. However, the independence level in functional activities in the early postoperative period was not influenced by the analgesia method.

The aim of this study was to conduct an overview of systematic reviews that summarizes the results about efficacy and safety from randomized controlled trials involving the various strategies used for postoperative pain management in children. We searched the Cochrane Database of Systematic Reviews, CINAHL, Database of Reviews of Effect, Embase, MEDLINE, and PsycINFO from the earliest date to January 24, 2016. This overview included 45 systematic reviews that evaluated interventions for postoperative pain in children. Out of 45 systematic reviews that investigated various interventions for postoperative pain in children, 19 systematic reviews (42%) presented conclusive evidence of efficacy. Positive conclusive evidence was reported in 18 systematic reviews (40%) for the efficacy of diclofenac, ketamine, caudal analgesia, dexmedetomidine, music therapy, corticosteroid, epidural analgesia, paracetamol, and/or nonsteroidal anti-inflammatory drugs and transversus abdominis plane block. Only one systematic review reported conclusive evidence of equal efficacy that involved a comparison of dexmedetomidine vs morphine and fentanyl. Safety of interventions was reported as conclusive in 14 systematic reviews (31%), with positive conclusive evidence for dexmedetomidine, corticosteroid, epidural analgesia, transversus abdominis plane block, and clonidine. Seven systematic reviews reported equal conclusive safety for epidural infusion, diclofenac intravenous vs ketamine added to opioid analgesia, bupivacaine, ketamine, paracetamol, and dexmedetomidine vs intravenous infusions of various opioid analgesics, oral suspension and suppository of diclofenac, only opioid, normal saline, no treatment, placebo, and midazolam. Negative conclusive statement for safety was reported in one systematic review for caudal analgesia vs noncaudal regional analgesia. More than half of systematic reviews included in this overview were rated as having medium methodological quality. Of 45 included

Background: Arthroscopic knee surgeries have a painful postoperative course, which often necessitates acute pain management. Among different analgesia techniques, Intra-articular injection is the technique of choice for many pain specialists, based on its confined effect to the surgical site (knee), lack of systemic effects and promotion of safe early ambulation. Objectives: The aim of this study was to compare analgesic effects of intra-articular meperidine, bupivacaine 0.5% or their combination after knee arthroscopic surgery. Patients and Methods: Sixty ASA class I-II patients’ candidates for arthroscopy knee surgery enrolled in a randomized double blind study to receive either 20 mL of bupivacaine 0.5%; 100 mg meperidine (diluted in normal saline) or bupivacaine 0.5% along with 100 mg meperidine. A written informed consent was obtained from all patients. Postoperative analgesia duration, VAS at 2, 6, 12 and 24 hours, the first analgesic request time, total fentanyl consumption in first 24 hours, patients’ satisfaction and adverse effects were recorded. Results: The bupivacaine-meperidine group had better duration of postoperative analgesia (P = 0.001), latter first analgesic request (P ≤ 0.001), lower total fentanyl consumption in first 24 hours after the operation (P = 0.001), less mean VAS at 2 hours (P = 0.001) and more patients’ overall satisfaction (P = 0.01) compared with each medication alone. VAS at 6, 12 and 24 postoperative hours were not different between the groups of study. No adverse effects were observed. Conclusions: Although postoperative intra-articular meperidine is a better alternative for bupivacaine, their combination could improve their analgesic effects compared with each other alone.

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.

2015-06-01

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.

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.

1998-01-01

A healthy 17-year-old male received standard intermittent doses of pethidine via a patient-controlled analgesia (PCA) pump for management of postoperative pain control. Twenty-three h postoperatively he developed a brief self-limited seizure. Both plasma pethidine and norpethidine were elevated in the range associated with clinical manifestations of central nervous system excitation. No other risk factors for CNS toxicity were identified. This method allowed frequent self-dosing of pethidine at short time intervals and rapid accumulation of pethidine and norpethidine. The routine use of pethidine via PCA even for a brief postoperative analgesia should be reconsidered.

To compare the performance of ibuprofen vs codeine for postoperative pain management after tonsillectomy as measured by need for emergency department (ED) treatment for pain and/or dehydration. Retrospective case series with chart review. Tertiary children's hospital. Consecutive series of patients who underwent tonsillectomy with or without adenoidectomy at a tertiary children's hospital. Patients were categorized based on the type of postoperative pain management (acetaminophen with codeine vs acetaminophen and ibuprofen). The main outcome measure was the proportion of patients requiring ED visits or inpatient admissions for inadequate pain control or dehydration. Secondary measures included antibiotic use, postoperative hemorrhage, need for return to the operating room, vomiting, and oral diet tolerance. Patients in the ibuprofen/acetaminophen group were younger than those in the codeine/acetaminophen group (6.2 vs 8.1 years, P < .05). Patients in the codeine/acetaminophen group were more likely to use antibiotics in the postoperative period (50.3% vs 5.9%, P < .05). The proportion of patients requiring ED visits or inpatient admission for dehydration was not significantly different between the groups (5.1% for codeine, 2.7% for ibuprofen, P = .12). Multivariable analysis controlling for age and antibiotic use showed no difference in ED visits or admission for dehydration (P = .09). There was no difference between the groups for any of the secondary measures. Ibuprofen with acetaminophen represents a safe and acceptable analgesic alternative to codeine and acetaminophen in patients undergoing pediatric tonsillectomy. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

2012-10-01

We conducted a retrospective study to evaluate the effectiveness of intravenous patient-controlled analgesia (IVPCA) in the early postoperative period after upper abdominal gastrointestinal surgery. We also evaluated the postoperative effects of intraoperative analgesic dosage in patients after this surgery. A total of 59 adult patients classified as ASA 1-3 were allocated to one of two groups: Group A, 23 patients who requested IVPCA more than 50 times, and Group B, 36 patients with fewer than 50 requests. IVPCA was induced using morphine 1 mg x ml(-1) without a base dose. The bolus dose was 1 ml and the lock-out time was 5 min. There was no significant difference between the two groups in the total intraoperative remifentanil dosage/body weight/surgical duration, predicted effect-site concentration of fentanyl during extubation, and utilization of flurbiprofen. The doses of morphine were significantly higher, and the visual analogue scale scores for pain at rest and during movement tended to be lower in group A than in group B. The results of this study suggest that the effects of intraoperative analgesics may not be significant. Patients who had received the above mentioned anesthetic regimen intraoperatively also required full postoperative analgesia as well.

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.

2015-01-01

BACKGROUND: Access to postoperative acute pain treatment is an important component of perioperative care and is frequently managed by a multidisciplinary team of anesthesiologists, surgeons, pharmacists, technicians and nurses. In some developing countries, treatment modalities are often not performed due to scarce health care resources, knowledge deficiencies and cultural attitudes. OBJECTIVES: In advance of a comprehensive knowledge translation initiative, the present study aimed to determine the perspectives, perceptions and experiences of anesthesia residents regarding postoperative pain management strategies. METHODS: The present study was conducted using a qualitative assessment strategy in a large teaching hospital in Rwanda. During two sessions separated by seven days, a 10-participant semistructured focus group needs analysis was conducted with anesthesia residents at the Centre Hospitalier Universitaire de Kigali (Kigali, Rwanda). Field notes were analyzed using interpretative and descriptive phenomenological approaches. Participants were questioned regarding their perspectives, perceptions and experiences in pain management. RESULTS: The responses from the focus groups were related to five general areas: general patient and medical practice management; knowledge base regarding postoperative pain management; pain evaluation; institutional/system issues related to protocol implementation; and perceptions about resource allocation. Within these areas, challenges (eg, communication among stakeholders and with patients) and opportunities (eg, on-the-job training, use of protocols, routine pain assessment, participation in resource allocation decisions) were identified. CONCLUSIONS: The present study revealed the prevalent challenges residents perceive in implementing postoperative pain management strategies, and offers practical suggestions to overcoming them, primarily through training and the implementation of practice recommendations.

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.

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

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.

The physiological and psychological stress of surgery and postoperative pain can leave patients more susceptible to infection and complications. The present study was designed to determine whether two interventions, patient teaching (PT) for pain management and relaxation/music (RM), reduced cortisol levels, an indicator of stress, following abdominal surgery. Patients (18-75 years) were randomly assigned to receive PT, RM, a combination of the two, or usual care; the 205 patients with both pre- and posttest cortisol values were analyzed. A 2 × 2 factorial design was used to compare groups for PT effects and RM effects. Stress was measured by salivary cortisol before and after 20-min tests of the interventions in the morning and afternoon of postoperative Day 2. Saliva was stimulated with lemon juice and analyzed with high-sensitivity salivary cortisol enzyme immunoassay. Comparisons using analysis of covariance (ANCOVA), controlling for baseline levels, showed no PT effect or RM effect on cortisol in the morning or afternoon. Post hoc ANCOVA showed no significant effects when intervention groups were compared to the control group. Although in previous studies, RM reduced pain and music reduced cortisol on Day 1, in the present study the cortisol response to surgery was not attenuated by PT or RM on Day 2. The RM intervention can be used for pain but needs to be further tested for effects on plasma cortisol in abdominal surgery patients on their first postoperative day.

While prevalent in everyday life, smartphones are also finding increasing use as a medical care adjunct. The use of smartphone technology as a postoperative cosmetic surgery adjunct for care has received little attention in the literature. The purpose of this effort was to assess the potential efficacy of a smartphone-based cosmetic surgery early postoperative follow-up program. Specifically, could smartphone photography provided by the patient to the plastic surgeon in the first few days after surgery allay patient's concerns, improve the postoperative experience and, possibly, detect early complications? From August 2015 to March 2016 a smartphone-based postoperative protocol was established for patients undergoing cosmetic procedures. At the time of discharge, the plastic surgeon sent a text to the patient with instructions for the patient to forward a postoperative photograph of the operated area within 48 to 72 hours. The plastic surgeon then made a return call/text that same day to review the patient's progress. A postoperative questionnaire evaluated the patients' postoperative experience and satisfaction with the program. A total of 57 patients were included in the study. Fifty-two patients responded to the survey. A total of 50 (96.2%) patients reported that the process improved the quality of their postoperative experience. The protocol allowed to detect early complications in 3 cases. The physician was able to address and treat the complications the following day prior to the scheduled clinic follow up. The smartphone can be effectively utilized by the surgeon to both enhance the patient's postoperative experience and alert the surgeon to early postoperative problems. 4. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Enhanced recovery protocols frequently use multimodal postoperative analgesia to improve postoperative outcomes in patients undergoing colorectal surgery. The purpose of this study was to evaluate liposomal bupivacaine use in transversus abdominis plane blocks on postoperative pain scores and opioid use after colorectal surgery. This was a retrospective cohort study comparing outcomes between patients receiving nonliposomal anesthetic (n = 104) and liposomal bupivacaine (n = 303) blocks. The study was conducted at a single tertiary care center. Patients included those identified within an institutional database as inpatients undergoing colorectal procedures between 2013 and 2015 who underwent transversus abdominis plane block for perioperative analgesia. The study measured postoperative pain scores and opioid requirements. Patients receiving liposomal bupivacaine had significantly lower pain scores for the first 24 to 36 postoperative hours. Pain scores were similar after 36 hours. The use of intravenous opioids among the liposomal bupivacaine group decreased by more than one third during the hospitalization (99.1 vs 64.5 mg; p = 0.040). The use of ketorolac was also decreased (49.0 vs 18.3 mg; p < 0.001). In subgroup analysis, the decrease in opioid use was observed between laparoscopic and robotic procedures but not with laparotomies. No significant differences were noted in the use of oral opioids, acetaminophen, or ibuprofen. Postoperative length of stay and total cost were decreased in the liposomal bupivacaine group but did not achieve statistical significance. The study was limited by its retrospective, single-center design and heterogeneity of block administration. Attenuated pain scores observed with liposomal bupivacaine use were associated with significantly lower intravenous opioid and ketorolac use, suggesting that liposomal bupivacaine-containing transversus abdominis plane blocks are well aligned with the opioid-reducing goals of many enhanced

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

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

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.

Early clinical outcomes following laparoscopic inguinal hernia repair.

PubMed

Tolver, Mette Astrup

2013-07-01

Laparoscopic inguinal hernia repair (TAPP) has gained increasing popularity because of less post-operative pain and a shorter duration of convalescence compared with open hernia repair technique (Lichtenstein). However, investigation of duration of convalescence with non-restrictive recommendations, and a procedure-specific characterization of the early clinical outcomes after TAPP was lacking. Furthermore, optimization of the post-operative period with fibrin sealant versus tacks for fixation of mesh, and the glucocorticoid dexamethasone versus placebo needed to be investigated in randomized clinical trials. The objective of this PhD thesis was to characterize the early clinical outcomes after TAPP and optimize the post-operative period. The four studies included in this thesis have investigated duration of convalescence and procedure-specific post-operative pain and other early clinical outcomes after TAPP. Furthermore, it has been shown that fibrin sealant can improve the early post-operative period compared with tacks, while dexamethasone showed no advantages apart from reduced use of antiemetics compared with placebo. Based on these findings, and the existing knowledge, 3-5 days of convalescence should be expected when 1 day of convalescence is recommended and future studies should focus on reducing intraabdominal pain after TAPP. Fibrin sealant can optimize the early clinical outcomes but the risk of hernia recurrence and chronic pain needs to be evaluated. Dexamethasone should be investigated in higher doses.

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

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.

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.

There is good evidence that combining two different analgesics in fixed doses in a single tablet can provide better pain relief in acute pain and headache than either drug alone, and that the drug-specific benefits are essentially additive. This appears to be broadly true in postoperative pain and migraine headache across a range of different drug combinations, and when tested in the same and different trials. Adding caffeine to analgesics also increases the number of people obtaining good pain relief. Combinations of ibuprofen and caffeine are available without prescription in some parts of the world. To assess the analgesic efficacy and adverse effects of a single oral dose of ibuprofen plus caffeine for moderate to severe postoperative pain, using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, two clinical trial registries, and the reference lists of articles. The date of the most recent search was 1 February 2015. Randomised, double-blind, placebo- or active-controlled clinical trials of single dose oral ibuprofen plus caffeine for acute postoperative pain in adults. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data. We used the area under the pain relief versus time curve to derive the proportion of participants with at least 50% pain relief over six hours prescribed either ibuprofen plus caffeine or placebo. We calculated the risk ratio (RR) and number needed to treat to benefit (NNT). We used information on the use of rescue medication to calculate the proportion of participants requiring rescue medication and the weighted mean of the median time to use. We also collected information on adverse effects. We identified five randomised, double-blind studies with 1501 participants, but

To compare different levels of self-rated pain and determine if they predict anticipated early physical recovery in patients undergoing general and orthopaedic surgery. Previous research has indicated that average self-rated pain reflects patients' ability to recover the same day. However, there is a knowledge gap about the feasibility of using average pain ratings to predict patients' physical recovery for the next day. Descriptive, quantitative repeated measures. General and orthopaedic inpatients (n = 479) completed a questionnaire (October 2012-January 2015) about pain and recovery. Average pain intensity at rest and during activity was based on the Numeric Rating Scale and divided into three levels (0-3, 4-6, 7-10). Three out of five dimensions from the tool "Postoperative Recovery Profile" were used. Because few suffered severe pain, general and orthopaedic patients were analysed together. Binary logistic regression analysis showed that average pain intensity postoperative day 1 significantly predicted the impact on recovery day 2, except nausea, gastrointestinal function and bladder function when pain at rest and also nausea, appetite changes, and bladder function when pain during activity. High pain ratings (NRS 7-10) demonstrated to be a better predictor for recovery compared with moderate ratings (NRS 4-6), day 2, as it significantly predicted more items in recovery. Pain intensity reflected general and orthopaedic patients' physical recovery postoperative day 1 and predicted recovery for day 2. By monitoring patients' pain and impact on recovery, patients' need for support becomes visible which is valuable during hospital stays. © 2017 John Wiley & Sons Ltd.

This study was aimed to evaluate the efficacy of preemptive analgesia (PA) by using celecoxib combined with low-dose tramadol/acetaminophen (tramadol/APAP) in treating post-operative pain of patients undergoing unilateral total knee arthroplasty (TKA). A total of 132 patients scheduled for TKA were included in this study. Three-day pre-operative medication was administrated in PA group with subsequent effective intra- and post-operative multimodal analgesia, while control patients received multimodal analgesia without PA. Visual analog scale (VAS) was utilized to assess the pain intensity at rest and during movement. VAS scores of participants were recorded 3 days before surgery, 1 day, 3 days, 1 week, 3 weeks, 6 weeks, 3 months, 6 months, and 12 months postoperatively. Moreover, the length of hospital stay, expense of hospitalization, C-reactive protein (CRP) values during hospitalization, and complications during medication were also recorded. PA showed superiority over control at 3 weeks (P = 0.013) and 6 weeks (P = 0.046) in resting pain, and 1 week (P = 0.015), 3 weeks (P = 0.003), 6 weeks (P = 0.003) and 3 months (P = 0.012) postoperatively in movement pain. There was no statistically significant difference in the length of hospital stay, total expense, CRP values, as well as complications. Based on satisfactory intra- and post-operative analgesia, PA by 3-day administration of celecoxib and low-dose tramadol/APAP might be an effective and safe therapy regarding patients undergoing TKA in terms of alleviating post-operative pain.

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

Postoperative pain alters physiological functions and delays discharge. Perioperative local anesthetics are effective analgesics in the immediate 1- to 2-day postoperative period, but acute pain often lasts longer. The goal of this work was to develop a local anesthetic formulation adhering to an intraoperative implanted device that reduces pain for at least 3 days after surgery. Six groups, each with 8 rats, were studied. In a control group (group I), one 1.2-cm-long incision of the skin was followed by blunt dissection to separate the skin away from the underlying tissues and closing with 2 sutures. In 3 of the treatment groups, the same surgical procedure was used, with the subcutaneous space formed by the blunt dissection lined with a 1-cm square patch of hernia mesh coated with poly lactide co-glycolic acid microspheres containing approximately 17 mg of bupivacaine (group II), no drug (placebo; group III), or bupivacaine free-base powder (group IV). Uncoated mesh implants (group V) served as a secondary control. A standard bupivacaine solution (0.4 mL, 0.5%; 2-mg dose) was infiltrated subcutaneously 30 minutes before the surgery and served as a standard control (group VI). Mechanosensitivity of the skin was tested by the local subcutaneous muscle responses to cutaneous tactile stimulation by von Frey hairs with forces of 4 g (for allodynia) and 15 g (for hyperalgesia) preoperatively and for 7 postoperative days. Control rats (group I) showed mechanohypersensitivity, indicative of postoperative allodynia and hyperalgesia, for all 7 postoperative days. Mechanohyperalgesia in rats that received mesh coated with bupivacaine-releasing microspheres (group II) was reduced during this period to 13% of control postoperative values (P < 0.001); mesh coated with bupivacaine base (group IV) reduced it by 50% (P = 0.034). The placebo mesh (group III) and uncoated mesh (group V) caused no significant reduction of mechanohypersensitivity, and bupivacaine solution infiltrated

Postoperative pain is a common complication of laparoscopic living-donor nephrectomies (LLDNs). To determine whether intravenous (IV) acetaminophen administration post-LLDN influenced length of stay (LOS) when used for pain management. This single-center, retrospective study compared patients undergoing LLDN who had received IV acetaminophen for pain control versus those who did not between June 1, 2011, and November 30, 2015. Patient LOS, 30-day readmissions, frequency of pain assessments, patient-reported pain scores, and opioid administration were assessed. A total of 90 patients were included in the analysis (IV acetaminophen, n = 48; non-IV acetaminophen, n = 42). Patients who did not receive IV acetaminophen were more often older (48.8 ± 12.1 vs 39.3 ± 12.1 years; P = 0.012) and female (71.4% vs 47.9%; P < 0.001). The average LOS was similar between the 2 groups (median = 3.0; interquartile range = [3, 4] vs 3.5 [3, 4]; P = 0.737). The 30-day readmissions were higher in the IV acetaminophen group (16.7%) compared with the group not receiving IV acetaminophen (2.4%; P = 0.033). After the first postoperative day, the frequencies of pain assessments performed were similar among the 2 groups. There was no difference in average pain scores between the groups at any time after LLDN. Patients receiving IV acetaminophen were found to have no improvements in hospital LOS, average pain score, or opioid requirements compared with patients not receiving IV acetaminophen. Patients who received IV acetaminophen were also found to have a higher 30-day readmission rate.

The ability to identify and focus care to patients at higher risk of moderate to severe postoperative pain should improve analgesia and patient satisfaction, and may affect reimbursement. We undertook this multi-centre cross-sectional study to identify preoperative risk factors for moderate to severe pain after total hip (THR) and knee (TKR) replacement. A total of 897 patients were identified from electronic medical records. Preoperative information and anaesthetic technique was gained by retrospective chart review. The primary outcomes were moderate to severe pain (pain score ≥ 4/10) at rest and with activity on postoperative day one. Logistic regression was performed to identify predictors for moderate to severe pain. Moderate to severe pain was reported by 20 % at rest and 33 % with activity. Predictors for pain at rest were female gender (OR 1.10 with 95 % CI 1.01-1.20), younger age (0.96, 0.94-0.99), increased BMI (1.02, 1.01-1.03), TKR vs. THR (3.21, 2.73-3.78), increased severity of preoperative pain at the surgical site (1.15, 1.03-1.30), preoperative use of opioids (1.63, 1.32-2.01), and general anaesthesia (8.51, 2.13-33.98). Predictors for pain with activity were TKR vs. THR (1.42, 1.28-1.57), increased severity of preoperative pain at the surgical site (1.11, 1.04-1.19), general anaesthesia (9.02, 3.68-22.07), preoperative use of anti-convulsants (1.78, 1.32-2.40) and anti-depressants (1.50, 1.08-2.80), and prior surgery at the surgical site (1.28, 1.05-1.57). Our findings provide clinical guidance for preoperative stratification of patients for more intensive management potentially including education, nursing staffing, and referral to specialised pain management.

The objective of the study was to investigate the effect of a long acting local anesthetic infiltration around nephrostomy tract on pain control after percutaneous nephrolithotomy. Forty-six patients with kidney stones of >2 cm undergoing single access subcostal percutaneous nephrolithotomy (PCNL) were enrolled in the study. Patients were randomized to levobupivacaine (Group I) and saline (Group II) infiltration groups. Group I patients (n = 23) had 75 mg/30 cc levobupivacaine infiltration around the access site after placement of nephrostomy catheter. Group II patients had 30 cc saline infiltration. Postoperatively the patients were given narcotics on demand. Pain scores were collected using a visual analog scale (VAS) at 2, 4, 6, 8, 12 and 24 h postoperatively. The VAS scores, time to analgesic demand, ambulation, and duration of nephrostomy tube were compared between two groups. The mean age was 44 and 45 years in group I and II patients. There were no significant differences between the two groups with regard to demographics, surgery or stone characteristics. Comparison of pain scores at all postoperative time points was not statistically significant between the two groups. Time to first analgesic demand and total narcotic analgesic dose per patient were 1.2 ± 1.05 and 4.04 ± 1.57 h; and 96 and 112 mg for group I and II patients (p = 0.009 and p = 0.41, respectively). Ambulation time and duration of nephrostomy tube were also similar. Infiltration of nephrostomy tract site with levobupivacaine does not have a superior effect compared to saline on postoperative pain control in patients undergoing PCNL.To prolong analgesia, the effect of intermittent tract injections or continuous infusion of local anesthetics for the postoperative maintenance of the local anesthetic effect seems worth to investigate in future studies.

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.

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.

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.

PURPOSE: To investigate whether patient-controlled oral analgesia (PCOA) used by individuals receiving a total knee replacement could reduce pain, increase patient satisfaction, reduce opioid use and/or reduce opioid side effects when compared with traditional nurse (RN)-administered oral analgesia. METHODS: Patients who underwent an elective total knee replacement at a quaternary care centre (Toronto Western Hospital, Toronto, Ontario) were randomly assigned to either PCOA or RN-administered short-acting oral opioids on postoperative day 2. Subjects in the RN group called the RN to receive their prescribed short-acting opioid. Subjects in the PCOA group kept a single dose of their prescribed oral opioid at their bedside and took this dose when they felt they needed it, to a maximum of one dose every 2 h. Study outcomes, collected on postoperative day 2, included pain (measured by the Brief Pain Inventory – Short Form), patient satisfaction (measured by the Pain Outcome Questionnaire Satisfaction sub-scale – component II), opioid use (oral morphine equivalents), opioid side effects (nausea, pruritis and/or constipation) and knee measures (maximum passive knee flexion and pain at maximum passive knee flexion, performed on the operative knee). RESULTS: Study outcomes were analyzed twice. First, for a subset of 73 subjects who remained in their randomly assigned group (PCOA group, n=36; RN group, n=37), randomized analyses were performed. Second, for the larger sample of 88 subjects who were categorized by their actual method of receiving oral opioids (PCOA group, n=41; RN group, n=47), as-treated analyses were performed. There were no differences in study outcomes between the PCOA and RN groups in either analysis. CONCLUSION: PCOA was not superior to RN administration on study outcomes. However, PCOA did not increase opioid use or pain. PCOA remains an important element in the patient-centred care facility. PMID:20195553

To evaluate the ability of various subjective and objective measurements to determine the presence and degree of postoperative pain in cats. Randomized controlled prospective clinical study. 18 healthy client-owned cats. Cats were randomly assigned to 3 groups of 6: control, tenectomy, and onychectomy. Jugular catheters were placed the day prior to surgery. All surgeries were performed by the same surgeon, and all observations were made by the same blinded trained observer. One hour prior to surgery and at assigned intervals for 36 hours after surgery, heart rate, respiratory rate, and rectal temperature were measured. Scores were assigned for 3 interaction responses, including response to palpation, by use of simple descriptive scales, and to 2 pain assessments by use of visual analogue scales. Blood was collected to measure plasma beta-endorphin and cortisol concentrations. Butorphanol was administered to all cats before surgery and to any cat subjectively assessed to be experiencing pain after surgery. Only visual analogue scale scores and response to palpation scores differed significantly between control and surgical groups. Determination of the presence of pain in cats can be made on the basis of observation and interaction by a trained observer. Physiologic measurements, including plasma cortisol and beta-endorphin concentrations, did not differentiate between control cats and cats that underwent surgery.

Different fluid regimens are used in the clinical management of perioperative fluid therapy, but there still is the argument about which fluid regimen is better for patients. This study was mainly designed to compare different fluid regimens on postoperative pain and residual gas in patients undergoing laparoscopic cholecystectomy. A total of 100 patients were equally randomized to receive restrictive fluid infusion (n=50) with lactated Ringer (LR) solution 5 mL/kg/h or liberal fluid infusion (n=50), with 30 mL/kg/h lactated Ringer solution. Postoperative pain was evaluated at 1, 6, and 24 hours after surgery using a visual analog scale (VAS). Postoperative subdiaphragmatic residual gas was monitored by x-ray at 24 hours after surgery. Patients in the restrictive group had significantly higher VAS pain scores at 6 hours after surgery than those in the liberal group (P=0.009). The incidence of subdiaphragmatic residual gas in the restrictive group was higher than in the liberal group (P=0.045). Patients who had residual gas had higher VAS pain scores than those with no residual gas in the restrictive group at 6 hours after surgery (P=0.02). Patients undergoing laparoscopic cholecystectomy with restrictive fluid therapy may suffer more severe postoperative pain than those receiving liberal fluid therapy. It suggests that the higher incidence of subdiaphragmatic residual gas may have occurred with restrictive fluid therapy.

Barriers to postoperative pain management in hip fracture patients with dementia as evaluated by nursing staff.

This paper reports a study of the perceptions of nursing staff regarding barriers to postoperative pain management in hip fracture patients with dementia, their expectations, and facilitators offered by their employers to overcome these barriers. Patients with dementia are at high risk for insufficient postoperative pain treatment, mainly owing to inability to articulate or convey their pain experience. Nursing staff have an essential role in the treatment and care of patients who are vulnerable, and therefore unable to advocate for their own pain treatment. Questionnaires with both structured and open-ended questions were used to collect data from nursing staff members in seven university hospitals and ten city-center hospitals from March to May 2011. The response rate was 52% (n = 331). According to nursing staff, the biggest barrier in pain management was the difficulty in assessing pain owing to a patient's cognitive impairment (86%). Resisting care and restlessness among patients with dementia can lead to use of restraints, although these kinds of behavioral changes can point to the occurrence of pain. There were statistically significant differences between the sufficiency of pain management and barriers. Those who expected pain management to be insufficient identified more barriers than those who expected pain management to be sufficient (p < .001). Further updating education for nursing staff in pain detection and management is needed so that nursing staff are also able to recognize behavioral symptoms as potential signs of pain and provide appropriate pain management.

The purpose of this study was to evaluate and compare the postoperative level of pain after activation of irrigants using EndoActivator with conventional needle irrigation during root canal therapy. In this prospective randomised clinical trial, 72 symptomatic irreversible pulpitis patients were selected. Based on block randomisation after routine root canal preparation, patients were assigned to two groups. In group EN, procedures were performed with endodontic irrigating needle (n = 36) while group EA received activation using EndoActivator (n = 36) in the final irrigation protocol. All the participants were called through phone at 8, 24 and 48 h to analyse pain score using visual analogue scale. Those patients who developed pain were prescribed ibuprofen 200 mg. Pain score and frequency of tablet intake were recorded and statistically analysed. Results showed that group EA resulted in significantly less postoperative pain and analgesics intake than group EN. In conclusion, within the limitations of this study, the activation of irrigants using EndoActivator can be considered an effective method for reducing postoperative pain. © 2014 Australian Society of Endodontology.

We report on the design and implementation of a study protocol entitled Acupuncture randomised trial for post anaesthetic recovery and postoperative pain - a pilot study (ACUARP) designed to investigate the effectiveness of acupuncture therapy performed in the perioperative period on post anaesthetic recovery and postoperative pain. The study is designed as a randomised controlled pilot trial with three arms and partial double blinding. We will compare (a) press needle acupuncture, (b) no treatment and (c) press plaster acupressure in a standardised anaesthetic setting. Seventy-five patients scheduled for laparoscopic surgery to the uterus or ovaries will be allocated randomly to one of the three trial arms. The total observation period will begin one day before surgery and end on the second postoperative day. Twelve press needles and press plasters are to be administered preoperatively at seven acupuncture points. The primary outcome measure will be time from extubation to 'ready for discharge' from the post anaesthesia care unit (in minutes). The 'ready for discharge' end point will be assessed using three different scores: the Aldrete score, the Post Anaesthetic Discharge Scoring System and an In-House score. Secondary outcome measures will comprise pre-, intra- and postoperative variables (which are anxiety, pain, nausea and vomiting, concomitant medication). The results of this study will provide information on whether acupuncture may improve patient post anaesthetic recovery. Comparing acupuncture with acupressure will provide insight into potential therapeutic differences between invasive and non-invasive acupuncture techniques.

Wound infiltration at the end of carotid endarterectomy under general anaesthesia is a simple technique that can be delegated to the surgeon. It was hypothesised that this technique could improve early post-operative analgesia by reducing the need for post-operative opioids. Forty patients underwent carotid endarterectomy under general anaesthesia with desflurane and remifentanil supplemented with morphine for post-operative analgesia. In a prospective double-blinded randomised study, patients were allocated pre-operatively to receive either subcutaneous infiltration of both wound edges with 20 ml of 0.75% ropivacaine or infiltration with isotonic saline. The primary outcome was morphine consumption while in the post-anaesthesia care unit (PACU). Pain scores at rest and movement, sedation, and patient satisfaction were the other main outcomes used to assess post-operative analgesia. The median dose of morphine administered in the PACU was 2 mg [0-3] in the ropivacaine vs. 4 mg [3-6] in the placebo group (P = 0.0004, Mann-Whitney's test). Pain at rest and at movement was lower in the ropivacaine group throughout observation in the PACU. No difference was found for both pain and opioid consumption after discharge from the PACU or for patient satisfaction. Sedative events in the early post-operative period were less frequent in the ropivacaine group. Local anaesthetic wound infiltration performed before closure reduces the need for additional opioids, lowers the immediate post-operative pain and improves alertness. These results argue for the use of local infiltration anaesthesia for carotid endarterectomy. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

We retrospectively examined esophageal cancer patients who received enteral nutrition (EN) to clarify the validity of early EN compared with delayed EN. A total of 103 patients who underwent transthoracic esophagectomy with three-field lymphadenectomy for esophageal cancer were entered. Patients were divided into two groups; Group E received EN within postoperative day 3, and Group L received EN after postoperative day 3. The clinical factors such as days for first fecal passage, the dose of postoperative albumin infusion, differences of serum albumin value between pre- and postoperation, duration of systematic inflammatory response syndrome (SIRS), incidence of postoperative infectious complication, and use of total parenteral nutrition (TPN) were compared between the groups. The statistical analyses were performed using Mann-Whitney U test and Chi square test. The statistical significance was defined as p < 0.05. Group E showed fewer days for the first fecal passage (p < 0.01), lesser dose of postoperative albumin infusion (p < 0.01), less use of TPN (p < 0.01), and shorter duration of SIRS (p < 0.01). However, there was no significant difference in postoperative complications between the two groups. Early EN started within 3 days after esophagectomy. It is safe and valid for reduction of albumin infusion and TPN, for promoting early recovery of intestinal movement, and for early recovery from systemic inflammation. PMID:24067386

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.

We hypothesised, that the inclusion of the ilium for multilevel lumbosacral fusions reduces the incidence of postoperative sacroiliac joint (SIJ) pain. The primary objective of this study was to compare the frequency of postoperative SIJ pain in patients undergoing multilevel stabilization with and without sacropelvic fixation for multilevel degenerative spine disease. In addition, we aimed at identifying factors that may predict the worsening or new onset of postoperative SIJ pain. A total of 63 patients with multisegmental fusion surgery with a minimum follow up of 12 months were evaluated. 34 patients received sacral fixation (SF group) and 29 patients received an additional sacropelvic fixation device (SPF group). Primary outcome parameters were changes in SIJ pain between the groups and the influence of pelvic parameters, the patient́s age, the patient́s body mass index (BMI) and the length of the stabilization on the SIJ pain. Between the two surgical groups there were no differences concerning age (p=0.3), BMI (p=0.56), length of follow up (p=0.96), length of the construct (p=0.56). In total 31.7% of the patients had a worsening/new onset of SIJ pain after surgery. An additional fixation of the SIJ with iliac screws or iliosacral plate did not have an influence on the SIJ pain (p=0.67). Likewise, pelvic parameters were not predictive for the outcome of the SIJ pain. Only an increased preoperative BMI correlated with a higher chance of a new onset of SIJ pain (p=0.037). In our retrospective study there was no influence of a sacropelvic fixation techniques on the SIJ pain in patients with multilevel degenerative spine disease after multilevel stabilization surgeries. The patients' BMI is the only preoperative factor that correlated with a higher incidence to develop postoperative SIJ pain, independently of the implantation of a sacropelvic fixation device.

To define likely targets (i.e. glia) and protocols (analgesic combinations) to improve postoperative pain outcomes and reduce chronic pain after surgery. Specifically, to assess the antihyperalgesic effects of the dexketoprofen : tramadol (DEX : TRM) combination, exploring the implication of glial activation. In a mouse model of postincisional pain, we evaluated mechanical nociceptive thresholds (Von Frey) for 21 days postoperatively. We assessed DEX and TRM alone and combined (1 : 1 ratio) on postoperative hyperalgesia (POH, day 1) and delayed latent pain sensitisation (substantiated by a naloxone challenge; PS, day 21). The interactions were analysed using isobolograms, and concomitant changes in spinal glial cell activation were measured. On day 1, DEX completely blocked POH, whereas TRM induced 32% inhibition. TRM, but not DEX, partially (47%) protected against PS, at 21 days. Co-administration of DEX : TRM (1 : 1 ratio) showed additivity for antihyperalgesia. Both drugs and their combination totally inhibited surgery-induced microglia activation on day 1, but had no effect on surgery-induced astrocyte activation (1 day) or re-activation after naloxone (21 days). The DEX : TRM combination could have clinical advantages: a complete prevention of POH after surgery, together with a substantial (48%) inhibition of the development of PS by TRM. Microglia, but not astrocyte activation, could play a relevant role in the development of postoperative pain hypersensitivity. © 2016 Royal Pharmaceutical Society.

Cardiac surgery (CS) ranks among the most frequently performed interventions worldwide and persistent postoperative pain (PPP) has been recognized as a relevant clinical outcome in this context. We aimed to evaluate its incidence, characteristics, associated factors and patient's quality of life (QoL). Observational prospective study conducted in patients undergoing CS in a tertiary university hospital. PPP was defined as persistent pain after surgery with higher than 3 months' duration, after excluding other causes of pain. We used a set of questionnaires for data collection: Pain Catastrophizing Scale, Duke Health Profile, Brief Pain Inventory Short Form, McGill Pain Questionnaire Short Form, Douleur Neuropathique en 4 Questions and standardized questions regarding pain periodicity. A total of 288 patients have completed the study and 43% presented PPP assessed at 3 months (PPP3M); out of which 84% were not under any treatment. PPP patients reported significantly lower QoL, and a neuropathic pain (NP) component was present in 50% of them. Younger age, female gender, higher body mass index, catastrophizing, coronary artery bypass graft, osteoarthritis, history of previous surgery (excluding sternotomy) and moderate to severe acute postoperative pain were independent predictors of PPP3M. This is the first study comprehensively describing PPP after CS and identifying NP in half of them. Our results support the important role that PPP plays after CS in considering its interference in patients' daily life and their lower QoL, which deserves the attention of health care professionals in order to improve prevention, assessment and treatment of these patients. WHAT DOES THIS STUDY ADD?: This study comprehensively describes persistent postoperative pain (PPP) after cardiac surgery (CS) and identifies neuropathic pain (NP) in half of them.

OBJECTIVE To evaluate agreement between observers with different training and experience for assessment of postoperative pain and sedation in cats by use of a dynamic and interactive visual analog scale (DIVAS) and for assessment of postoperative pain in the same cats with a multidimensional composite pain scale (MCPS). DESIGN Randomized, controlled, blinded study. ANIMALS 45 adult cats undergoing ovariohysterectomy. PROCEDURES Cats received 1 of 3 preoperative treatments: bupivacaine, IP; meloxicam, SC with saline (0.9% NaCl) solution, IP, (positive control); or saline solution only, IP (negative control). All cats received premedication with buprenorphine prior to general anesthesia. An experienced observer (observer 1; male; native language, Spanish) used scales in English, and an inexperienced observer (observer 2; female; native language, French) used scales in French to assess signs of sedation and pain. Rescue analgesia was administered according to MCPS scoring by observer 1. Mean pain and sedation scores per treatment and time point, proportions of cats in each group with MCPS scores necessitating rescue analgesia, and mean MCPS scores assigned at the time of rescue analgesia were compared between observers. Agreement was assessed by intraclass correlation coefficient determination. Percentage disagreement between observers on the need for rescue analgesia was calculated. RESULTS Interobserver agreements for pain scores were good, and that for sedation scores was fair. On the basis of observer 1's MCPS scores, a greater proportion of cats in the negative control group received rescue analgesia than in the bupivacaine or positive control groups. Scores from observer 2 indicated a greater proportion of cats in the negative control group than in the positive control group required rescue analgesia but identified no significant difference between the negative control and bupivacaine groups for this variable. Overall, disagreement regarding need for rescue

Spiritual elements play an important role in the recovery process from acute postoperative pain. This study was conducted to assess the effect of pray meditation on postoperative pain reduction and physiologic responds among muslim patients who underwent cesarean surgery under spinal anesthesia. This double-blinded randomized clinical trial study was conducted among muslim patients who underwent cesarean surgery under spinal anesthesia during 2011-2013 at tertiary regional and teaching hospital in Lorestan, Iran. The patients were randomly divided into interventional group (n=80) and control group (n=80). For about 20 minutes using a disposable phone mentioned and listened to pray meditation "Ya man esmoho davaa va zekroho shafa, Allahomma salle ala mohammad va ale mohammad" in interventional group and phone off in control group. Before and during pray meditation, 30, 60 minutes, 3 and 6 hours after pray meditation pain intensity, blood pressure, heart rate and respiratory rate were measured. No statistically significant improvement in pain score was found before and during pray meditation, 30, 60 minutes after pray meditation (P>0.05). Statistically significant improvement in pain score was found at 3 and 6 hours after pray meditation than control group (1.5 ± 0.3 vs. 3 ± 1.3, P=0.030) and (1.3 ± 0.8 vs. 3 ± 1.1, P=0.003). However, there was no significant difference in the physiological responses (systolic and diastolic blood pressure, respiration, and heart rate) any time between the groups. Religion and spirituality intervention such as pray meditation could be used as one of non-pharmacological pain management techniques for reducing pain after cesarean surgery. Also, Pray meditation provides less postoperative nausea and vomiting (PONV) and more relaxation.
