Context This article discusses the anesthetic considerations in patients undergoing bariatric surgery in the preoperative, intraoperative, and postoperative phases of surgery. Evidence Acquisition This review includes studies involving obese patients undergoing bariatric surgery. Searches have been conducted in PubMed, MEDLINE, EMBASE, Google Scholar, Scopus, and Cochrane Database of Systematic Review using the terms obese, obesity, bariatric, anesthesia, perioperative, preoperative, perioperative, postoperative, and their combinations. Results Obesity is a major worldwide health problem associated with many comorbidities. Bariatric surgery has been proposed as the best alternative treatment for extreme obese patients when all other therapeutic options have failed. Conclusions Anesthetists must completely assess the patients before the surgery to identify anesthesia- related potential risk factors and prepare for management during the surgery. PMID:29430407

As bariatric surgery rates continue to climb, anaemia will become an increasing concern. We assessed the prevalence of anaemia and length of hospital stay in patients undergoing bariatric surgery. Prospective data (anaemia [haemoglobin <12 g/dL], haematinics and length of hospital stay) was analysed on 400 hundred patients undergoing elective laparoscopic bariatric surgery. Results from a prospective database of 1530 patients undergoing elective general surgery were used as a baseline. Fifty-seven patients (14%) were anaemic pre-operatively, of which 98% were females. Median MCV (fL) and overall median ferritin (μg/L) was lower in anaemic patients (83 vs. 86, p=0.001) and (28 vs. 61, p<0.0001) respectively. In the elective general surgery patients, prevalence of anaemia was similar (14% vs. 16%) but absolute iron deficiency was more common in those undergoing bariatric surgery; microcytosis p<0.0001, ferritin <30 p<0.0001. Mean length of stay (days) was increased in the anaemic compared to in the non-anaemic group (2.7 vs. 1.9) and patients who were anaemic immediately post-operatively, also had an increased length of stay (2.7 vs. 1.9), p<0.05. Absolute iron deficiency was more common in patients undergoing bariatric surgery. In bariatric patients with anaemia there was an overall increased length of hospital stay.

Many patients with adult congenital heart disease will require cardiac surgery during their lifetime, and some will have concomitant tricuspid regurgitation. However, the optimal management of significant tricuspid regurgitation at the time of cardiac surgery remains unclear. We assessed the determinants of adverse outcomes in patients with adult congenital heart disease and moderate or greater tricuspid regurgitation undergoing cardiac surgery for non-tricuspid regurgitation-related indications. All adult patients with congenital heart disease and greater than moderate tricuspid regurgitation who underwent cardiac surgery for non-tricuspid regurgitation-related indications were included in a retrospective study at the Schneeweiss Adult Congenital Heart Center. Cohorts were defined by the type of tricuspid valve intervention at the time of surgery. The primary end point of interest was a composite of death, heart transplantation, and reoperation on the tricuspid valve. A total of 107 patients met inclusion criteria, and 17 patients (17%) reached the primary end point. A total of 68 patients (64%) underwent tricuspid valve repair, 8 patients (7%) underwent tricuspid valve replacement, and 31 patients (29%) did not have a tricuspid valve intervention. By multivariate analysis, moderate or greater postoperative tricuspid regurgitation was associated with a hazard ratio of 6.12 (1.84-20.3) for the primary end point (P = .003). In addition, failure to perform a tricuspid valve intervention at the time of surgery was associated with an odds ratio of 4.17 (1.26-14.3) for moderate or greater postoperative tricuspid regurgitation (P = .02). Moderate or greater postoperative tricuspid regurgitation was associated with an increased risk of death, transplant, or reoperation in adult patients with congenital heart disease undergoing cardiac surgery for non-tricuspid regurgitation-related indications. Concomitant tricuspid valve intervention at the time of cardiac surgery should

Background A prolonged stay in an intensive care unit (ICU) after cardiac surgery with cardiopulmonary bypass (CPB) increases the cost of care as well as morbidity and mortality. Several predictive models aim at identifying patients at risk of prolonged ICU stay after cardiac surgery with CPB, but almost all of them involve a preoperative assessment for proper resource management, while one – the Open-Heart Intraoperative Risk (OHIR) score – focuses on intra-operative manipulatable risk factors for improving anesthetic care and patient outcome. Objective We aimed to revalidate the OHIR score in a different context. Materials and methods The ability of the OHIR score to predict a prolonged ICU stay was assessed in 123 adults undergoing cardiac surgery (both coronary bypass graft and valvular surgery) with CPB at two tertiary university hospitals between January 2013 and December 2014. The criteria for a prolonged ICU stay matched a previous study (ie, a stay longer than the median). Results The area under the receiver operating characteristic curve of the OHIR score to predict a prolonged ICU stay was 0.95 (95% confidence interval 0.90–1.00). The respective sensitivity, specificity, positive predictive value, and accuracy of an OHIR score of ≥3 to discriminate a prolonged ICU stay was 93.10%, 98.46%, 98.18%, and 95.9%. Conclusion The OHIR score is highly predictive of a prolonged ICU stay among intraopera-tive patients undergoing cardiac surgery with CPB. The OHIR comprises of six risk factors, five of which are manipulatable intraoperatively. The OHIR can be used to identify patients at risk as well as to improve the outcome of those patients.

To evaluate the effect of multidisciplinary blood management strategy in adults patients undergoing valvular heart surgery. A multidisciplinary patient blood management (PBM) strategy was instituted in Fuwai Hospital since January 2009. It includes Establishment of a multidisciplinary blood transfusion management team and designation of a coordinator; Enactment perioperative transfusion triggers (Hb < 80 g/L) for adults patients undergoing cardiac surgery; recommendation of antifibrinolytics, cell salvage, reduced cardiopulmonary bypass circuit; setting up Blood Consumption Announcement and Scoring System, which regularly publishes notifications of blood volume consumed per case, per single procedure and per surgeon. Clinical date before and after multidisciplinary patient blood management strategy will be presented. A total of 3 951 consecutive patients underwent Valvular Heart Surgery were analyzed. 1 713 cases were in pre-PBM group, and 2 238 cases were in post-PBM group. Both incidence and average units of allogeneic red blood cell transfusion perioperatively in post-PBM group were decreased (28.5% vs 75.3%, P = 0.000, and 1.2 U vs 4.0 U, P = 0.000). The postoperative length of stay in hospital and incidence of pneumonia were reduced in post-PBM group (8.2 d vs 10.5 d, P = 0.02, and 2.7% vs 3.5%, P = 0.04). The post-PBM group had lower in-hospital mortality (0.6% vs 1.2%, P = 0.000). Multidisciplinary patient blood management strategy significantly reduced blood transfusion, morbidity and mortality in patients underwent valvular heart surgery. It save plenty of blood resources.

To evaluate the prophylactic use of dexamethasone with sevoflurane in outpatient anorectal surgery. Randomized, controlled study. Operating room and Postanesthesia Care Unit of a general hospital. 60 adult, ASA physical status I and II outpatients undergoing anorectal surgery. Patients were randomized to receive either dexamethasone 5 mg intravenously (IV; Group D; n = 30) or an equal volume of saline (Group S; n = 30) before anesthesia induction. Anesthesia was induced with propofol 2.5 mg.kg(-1), fentanyl two microg.kg(-1), and 2% lidocaine one mg.kg(-1) followed by placement of a Laryngeal Mask Airway. Frequency of postoperative nausea and vomiting (PONV), visual analog scale (VAS) pain scores, and patient satisfaction were recorded. Frequency of PONV and VAS pain scores were significantly lower in Group D than Group S (P < 0.05). The time required for "home readiness" was significantly shorter in Group D than Group S (P < 0.05). The prophylactic administration of 5 mg dexamethasone IV can reduce the frequency of PONV, lower VAS pain scores, facilitate recovery to home readiness, and improve satisfaction in outpatients undergoing anorectal surgery.

The available evidence shows that hypoxemia after Stanford Type-A acute aortic dissection (AAD) surgery is a frequent cause of several adverse consequences. The pathogenesis of postoperative hypoxemia after AAD surgery is complex, and ischemia/reperfusion and inflammation are likely to be underlying risk factors. Xenon, recognized as an ideal anesthetic and anti-inflammatory treatment, might be a possible treatment for these adverse effects. The trial is a prospective, double-blind, 4-group, parallel, randomized controlled, a signal-center clinical trial. We will recruit 160 adult patients undergoing Stanford type-A AAD surgery. Patients will be allocated a study number and will be randomized on a 1:1:1:1 basis to receive 1 of the 3 treatment options (pulmonary inflated with 50% xenon, 75% xenon, or 100% xenon) or no treatment (control group, pulmonary inflated with 50% nitrogen). The aims of this study are to clarify the lung protection capability of xenon and its possible mechanisms in patients undergoing the Stanford type-A AAD surgery. This trial uses an innovative design to account for the xenon effects of postoperative oxygen impairment, and it also delineates the mechanism for any benefit from xenon. The investigational xenon group is considered a treatment intervention, as it includes 3 groups of pulmonary static inflation with 50%, 75%, and 100% xenon. It is suggested that future trials might define an appropriate concentration of xenon for the best practice intervention.

Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (P<0.001). Major hemorrhage or cardiac tamponade leading to reoperation occurred in 1.4% of the patients in the tranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures. (Funded by the Australian National Health and Medical Research Council and others; ATACAS Australia New Zealand

Objective Cyclosporin-A (CsA) has been reported to reduce myocardial infarct size in both the experimental and clinical settings. This protective effect is dependent on its ability to prevent the opening of the mitochondrial permeability transition pore, a critical determinant of cell death in the setting of acute ischaemia-reperfusion injury. Whether CsA can reduce the extent of peri-operative myocardial injury (PMI) in patients undergoing coronary artery bypass graft (CABG) surgery is unknown, and is investigated in this randomised controlled clinical trial. Methods 78 adult patients undergoing elective CABG surgery were randomised to receive either an intravenous bolus of CsA (2.5 mg/kg) or placebo administered after induction of anaesthesia and prior to sternotomy. PMI was assessed by measuring serum cardiac enzymes, troponin T (cTnT) and CK-MB at 0, 6, 12, 24, 48 and 72 h after surgery. Results There was no significant difference in mean peak cTnT levels between control (n=43) and CsA treatment (n=40) patients (0.56±0.06 ng/mL with control vs 0.35±0.05 ng/mL with CsA; p=0.07). However, in higher-risk patients with longer cardiopulmonary bypass times, there was a significant reduction in PMI with CsA therapy (p=0.049), with a reduced postoperative cTnT rise by 0.03 ng/mL for every 10 min, when compared with control. Conclusions In patients with longer cardiopulmonary bypass times, a single intravenous bolus of CsA administered prior to CABG surgery reduced the extent of PMI. PMID:24488610

Research was conducted to gain insight into potential clients' decisions to undergo plastic surgery, their perception of benefits and risks, their judgment of outcomes, and their selection of a plastic surgeon. Semistructured, open-ended interviews were conducted with 60 people who expressed interest in plastic surgery. Qualitative analysis revealed their "mental models" regarding influences on their decision to undergo plastic surgery and their choice of a surgeon. Interview results were used to design a Web-based survey in which 644 individuals considering plastic surgery responded. The desire for change was the most direct motivator to undergo plastic surgery. Improvements to physical well-being were related to emotional and social benefits. When prompted about risks, participants mentioned physical, emotional, and social risks. Surgeon selection was a critical influence on decisions to undergo plastic surgery. Participants gave considerable weight to personal consultation and believed that finding the "right" plastic surgeon would minimize potential risks. Findings from the Web-based survey were similar to the mental models interviews in terms of benefit ratings but differed in risk ratings and surgeon selection criteria. The mental models interviews revealed that interview participants were thoughtful about their decision to undergo plastic surgery and focused on finding the right plastic surgeon.

Although stapling is an alternative to hand-suturing in gastrointestinal surgery, recent trials specifically designed to evaluate differences between the two in surgery time, anastomosis time, and return to bowel activity are lacking. This trial compared the outcomes of the two in subjects undergoing open gastrointestinal surgery. Adult subjects undergoing emergency or elective surgery requiring a single gastric, small, or large bowel anastomosis were enrolled into this open-label, prospective, randomized, interventional, parallel, multicenter, controlled trial. Randomization was assigned in a 1:1 ratio between the hand-sutured group (n = 138) and the stapled group (n = 142). Anastomosis time, surgery time, and time to bowel activity were collected and compared as primary endpoints. A total of 280 subjects were enrolled from April 2009 to September 2010. Only the time of anastomosis was significantly different between the two arms: 17.6 ± 1.90 min (stapled) and 20.6 ± 1.90 min (hand-sutured). This difference was deemed not clinically or economically meaningful. Safety outcomes and other secondary endpoints were similar between the two arms. Mechanical stapling is faster than hand-suturing for the construction of gastrointestinal anastomoses. Apart from this, stapling and hand-suturing are similar with respect to the outcomes measured in this trial.

Background The obesity has achieved an alarming increase in recent years, which led this disease to global epidemic condition. Aim To evaluate the nutritional status as well as the quality of life of obese patients undergoing bariatric surgery. Methods A transversal study was conducted with obese adults of both genders who underwent bariatric surgery by Fobi-Capella technique for at least 30 days. It was evaluated: age, gender, marital status, occupation, weight before surgery, current weight, height, preoperative and current BMI, weight loss and loss of excess weight percentages, presence of clinical manifestations and food intolerances. Results The sample consisted of 70 patients, being 81.4% female, 37.1% aged 30 to 39 years, 58.6% were married, 41.4% have undergone the bariatric surgery in the last 12 months. It was observed a reduction in BMI from 37.2 kg/m2 (one to three months) to 28.9 kg/m2 (>12 months) and consequent increase in weight loss and loss of excess weight percentages. The most frequent clinical manifestation was alopecia (62.9%). The most reported food intolerance was on the red meat (24%). According to the Baros questionnaire, 50% of patients were classified as having good quality of life. Conclusion The operation of Fobi-Capella proved to be effective in promoting gradual and lasting weight loss. Quality of life was considered good in most patients, indicating that the operation had a positive impact on their lives. PMID:25409963

Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p <0.0005 and placebo: preoperative -0.14 ± 0.98 vs. postoperative -1.35 ± 1.23, p <0.0005). Patients taking piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease.

To evaluate the clinical efficacy of intravenous (IV) fluid warming in patients undergoing laparoscopic colorectal surgery. Adult patients undergoing laparoscopic colorectal surgery were randomly assigned to receive either IV fluids at room temperature (control group) or warmed IV fluids (warm fluids group). Each patient received a standardized goal-directed fluid regimen based on stroke volume variances. Oesophageal temperature was measured at 15 min intervals for 2 h after induction of anaesthesia. A total of 52 patients were enrolled in the study. The drop in core temperature in the warm fluids group was significantly less than in the control group 2 h after the induction of anaesthesia. This significant difference was seen from 30 min after induction. IV fluid warming was associated with a smaller drop in core temperature than room temperature IV fluids in laparoscopic colorectal surgery incorporating goal-directed fluid therapy. © The Author(s) 2016.

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

Adult spinal deformity (ASD) is an important problem to consider in the elderly. Although studies have examined the complications of ASD surgery and have compared functional and radiographic results of primary surgery versus revision, no studies have compared the costs of primary procedures with revisions. We assessed the in-hospital costs of these 2 surgery types in patients with ASD. The PearlDiver Database, a database of Medicare records, was used in this study. Mutually exclusive groups of patients undergoing primary or revision surgery were identified. Patients in each group were queried for age, sex, and comorbidities. Thirty-day readmission rates, 30-day and 90-day complication rates, and postoperative costs of care were assessed with multivariate analysis. For analyses, significance was set at P < 0.001. The average reimbursement of the primary surgery cohort was $57,078 ± $30,767. Reimbursement of revision surgery cohort was $52,999 ± $27,658. The adjusted difference in average costs between the 2 groups is $4773 ± $1069 (P < 0.001). The 30-day and 90-day adjusted difference in cost of care when sustaining any of the major medical complications in primary surgery versus revision surgery was insignificant. Patients undergoing primary and revision corrective procedures for ASD have similar readmission rates, lengths of stays, and complication rates. Our data showed a higher cost of primary surgery compared with revision surgery, although costs of sustaining postoperative complications were similar. This finding supports the decision to perform revision procedures in patients with ASD when indicated because neither outcomes nor costs are a hindrance to correction. Copyright © 2017 Elsevier Inc.

To determine if dogs that undergo laparotomy for cholecystectomy suffer from a greater number or magnitude of perianesthetic complications, including hypotension, hypothermia, longer recovery time, and lower survival rate, than dogs that undergo laparotomy for hepatic surgery without cholecystectomy. Retrospective cohort study. One hundred and three dogs, anesthetised between January 2007 and October 2011. The variables collected from the medical record included age, weight, gender, surgical procedure, pre-operative bloodwork, American Society of Anesthesiologists (ASA) status, emergency status, total bilirubin concentration, anesthetic agents administered, body temperature nadir, final body temperature, hypotension, duration of hypotension, blood pressure nadir, intraoperative drugs, anesthesia duration, surgery duration, time to extubation, final diagnosis, days spent in the intensive care unit (ICU), total bill, survival to discharge, and survival to follow-up. No significant difference in body temperature nadir, final temperature, presence of hypotension, duration of hypotension, blood pressure nadir, the use of inotropes, or final outcome was found between dogs undergoing cholecystectomy and dogs undergoing exploratory laparotomy for other hepatic disease. Dogs that had cholecystectomy had longer anesthesia durations and longer surgery durations than dogs that did not have cholecystectomy. No significant differences existed for temperature nadir (34.8 versus 35.3°C; non-cholecystectomy versus cholecystectomy), final temperature (35.6 versus 35.9°C), time to extubation (30 versus 49 minutes), duration of hypotension (27 versus 21 minutes), or MAP nadir (56 versus 55 mmHg). Hypotension occurred in 66% and 74% and inotropes were used in 64% and 53%, for non-cholecystectomy and cholecystectomy patients, respectively. Dogs that underwent cholecystectomies did not suffer a greater number of anesthesia complications than did dogs undergoing hepatic surgery without

The aim of the present study was to investigate changes in emotional state and the relationship between emotional state and demographic/clinical factors and coping style among gynecologic patients undergoing surgery. Using the Japanese version of the Profile of Mood States (POMS), 90 patients (benign disease: 32, malignancy: 58) were examined on three occasions: before surgery, before discharge, and 3 months after discharge. They were also examined using the Coping Inventory for Stressful Situations (CISS) on one occasion before discharge. The scores for the subscales depression, anger, and confusion were the highest after discharge while those for anxiety were the highest before surgery. The average scores of the POMS subscales for all subjects were within the normal range. With regard to the relationship between these emotional states and other factors, multiple regressions showed that the principal determinants of anxiety before surgery were religious belief, psychological symptoms during hospitalization and emotion-oriented (E) coping style; further, it was found that depression after discharge could be explained by chemotherapy, duration of hospitalization, and E coping style. The principal determinants of anger after discharge and vigor before surgery were length of education and E coping style, and severity of disease, chemotherapy, E coping style and task-oriented coping style, respectively. Those of post-discharge fatigue and confusion were length of education, psychological symptoms, and E coping style. In summary it is suggested that the following should be taken into account in patients undergoing gynecologic surgery: anxiety before surgery, depression, anger, and confusion after surgery, including coping styles.

Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, P<0.0001) and more likely to have diabetes with chronic complications, neurological complications, congestive heart failure, pulmonary disorders, coagulopathy, and renal failure. Lumbar fusion (P=0.0001) and lumbar fusion revision (P=0.0003) were associated with increased odds of postoperative infection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; P<0.001), whereas urban hospitals were associated with increased odds (OR, 2.14; P<0.14) of acquiring infection. Uninsured (OR, 1.62; P<0.0001) and patients with Medicaid (OR, 1.33; P<0.0001) were associated with higher odds of acquiring postoperative infection. C. difficile increased hospital length of stay by 8 days (P<0.0001), hospital charges by 2-fold (P<0.0001), and inpatient mortality to 4% from 0.11% (P<0.0001). C. difficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs

Inherited factor VII (FVII) deficiency is a rare coagulation disorder with variable haemorrhagic manifestations. In severely affected cases spontaneous haemarthroses leading to advanced arthropathy have been observed. Such cases may require surgery. Therapeutic options for bleeding prevention in FVII deficient patients undergoing surgery comprise various FVII preparations but the use of recombinant activated factor VII (rFVIIa) seems to be the treatment of choice. To present the outcome of orthopaedic surgery under haemostatic coverage of rFVIIa administered according to the locally established treatment regimen in five adult patients with FVII baseline plasma levels below 10 IU dL(-1). Two patients required total hip replacement (THR); three had various arthroscopic procedures. Recombinant activated factor VII was administered every 8 h on day of surgery (D0) followed by every 12-24 h for the subsequent 9-14 days, depending on the type of surgery. Factor VII plasma coagulation activity (FVII:C) was determined daily with no predefined therapeutic target levels. Doses of rFVIIa on D0 ranged from 18 to 37 μg kg(-1) b.w. and on the subsequent days--from 13 to 30 μg kg(-1) b.w. Total rFVIIa dose per procedure ranged from 16 to 37.5 mg, and the total number of doses per procedure was 16-31. None of our patients developed excessive bleeding including those in whom FVII:C trough levels returned nearly to the baseline level on the first post-op day. Preliminary results demonstrate that rFVIIa administered according to our treatment regimen is an effective and safe haemostatic agent for hypoproconvertinaemia patients undergoing orthopaedic surgery. © 2012 Blackwell Publishing Ltd.

People's experiences of suffering a lower limb fracture and undergoing surgery.

To describe people's experiences of suffering a lower limb fracture and undergoing surgery, from the time of injury through to the care given at the hospital and recovery following discharge. There is a lack of research on people's experiences of suffering a lower limb fracture and undergoing surgery - from injury to recovery. A qualitative approach was used. Interviews with nine participants were subjected to thematic content analysis. One theme was expressed: from realising the seriousness of the injury to regaining autonomy. Participants described feelings of frustration and helplessness when realising the seriousness of their injury. The wait prior to surgery was a strain and painful experience, and participants needed orientation for the future. They expressed feelings of vulnerability about being in the hands of staff during surgery. After surgery, in the postanaesthesia unit, participants expressed a need to have control and to feel safe in their new situation. To mobilise and regain their autonomy was a struggle, and participants stated that their recovery was extended. Participants found themselves in a new and unexpected situation and experienced pain, vulnerability and a striving for control during the process, that is, 'from realising the seriousness of the injury to regaining autonomy'. How this is managed depends on how the patient's needs are met by nurses. The nursing care received while suffering a lower limb fracture and undergoing surgery should be situation specific as well as individual specific. The safe performance of technical interventions and the nurse's comprehensive explanations of medical terms may help the patient to feel secure during the process. © 2013 John Wiley & Sons Ltd.

We sought to determine the impact of levosimendan on mortality following cardiac surgery based on large-scale randomized controlled trials (RCTs). We searched PubMed, Web of Science, Cochrane databases, and ClinicalTrials.gov for RCTs published up to December 2017, on levosimendan for patients undergoing cardiac surgery. A total of 25 RCTs enrolling 2960 patients met the inclusion criteria; data from 15 placebo-controlled randomized trials were included for meta-analysis. Pooled analysis showed that the all-cause mortality rate was 6.4% (71 of 1106) in the levosimendan group and 8.4% (93 of 1108) in the placebo group (odds ratio [OR], 0.76; 95% confidence interval [CI], 0.55-1.04; P = 0.09). There were no significant differences between the two groups in the rates of myocardial infarction (OR: 0.91; 95% CI, 0.68-1.21; P = 0.52), serious adverse events (OR: 0.84; 95% CI, 0.66-1.07; P = 0.17), hypotension (OR: 1.69; 95% CI, 0.94-3.03; P = 0.08), and low cardiac output syndrome (OR: 0.47; 95% CI, 0.22-1.02; P = 0.05). Levosimendan did not result in a reduction in mortality in adult cardiac surgery patients. Well designed, adequately powered, multicenter trials are necessary to determine the role of levosimendan in adult cardiac surgery. © 2018 The Authors.

The authors determined the pharmacokinetics of fentanyl 100 micrograms X kg-1 iv in patients undergoing elective abdominal aortic surgery. The mean (+/- SD) age of the ten patients was 67.2 +/- 8.7 yr; their mean weight was 78.5 +/- 13.7 kg. Seven patients had aortic aneurysm repair, and the other three patients had aortobifemoral grafts. Serum fentanyl concentrations were determined from samples drawn at increasing intervals over a 24-h period. A three-compartment pharmacokinetic model was fit to the concentration versus time data. Total drug clearance was 9.8 +/- 1.8 ml X min-1 X kg-1. The volume of distribution at steady-state (Vdss) was 5.4 +/- 1.9 X 1 kg-1. Elimination half-time was 8.7 +/- 2.5 h. There were no significant correlations between these pharmacokinetic parameters and patient's age, duration of aortic cross-clamping, duration of surgery, intraoperative blood loss, or volume of iv fluids given intraoperatively. In healthy volunteers or patients undergoing general surgery, other investigators report mean elimination half-times for fentanyl ranging from 1.7 to 4.4 h. The prolonged elimination half-time in patients having abdominal aortic surgery has important clinical implications. In particular, recovery from large doses will take much longer than would have been anticipated from previously published fentanyl pharmacokinetic data.

Cardiac surgery is a highly complex procedure which generates worsening of lung function and decreased inspiratory muscle strength. The inspiratory muscle training becomes effective for muscle strengthening and can improve functional capacity. To investigate the effect of inspiratory muscle training on functional capacity submaximal and inspiratory muscle strength in patients undergoing cardiac surgery. This is a clinical randomized controlled trial with patients undergoing cardiac surgery at Instituto Nobre de Cardiologia. Patients were divided into two groups: control group and training. Preoperatively, were assessed the maximum inspiratory pressure and the distance covered in a 6-minute walk test. From the third postoperative day, the control group was managed according to the routine of the unit while the training group underwent daily protocol of respiratory muscle training until the day of discharge. 50 patients, 27 (54%) males were included, with a mean age of 56.7±13.9 years. After the analysis, the training group had significant increase in maximum inspiratory pressure (69.5±14.9 vs. 83.1±19.1 cmH2O, P=0.0073) and 6-minute walk test (422.4±102.8 vs. 502.4±112.8 m, P=0.0031). We conclude that inspiratory muscle training was effective in improving functional capacity submaximal and inspiratory muscle strength in this sample of patients undergoing cardiac surgery.

Clinical predictors of perioperative mortality in geriatric patients undergoing emergent general surgery have not been well described. The purpose of this study was to determine the incidence of postoperative morbidity and mortality in geriatric patients and factors associated with mortality. A retrospective review of patients 65 years of age or older undergoing emergent general surgery at a public teaching hospital was performed over a 7-year period. Data collected included demographics, comorbidities, laboratory studies, perioperative morbidities, and mortality. Descriptive statistics and predictors of morbidity and mortality are described. The mean age was 74 years. Indications for surgery included small bowel obstruction (24%), diverticulitis (20%), perforated viscous (16%), and large bowel obstruction (9%). The overall complication rate was 41 per cent with six cardiac complications (14%) and seven perioperative (16%) deaths. Mean admission serum creatinine was significantly higher in patients who died (3.6 vs 1.5 mg/dL, P = 0.004). Mortality for patients with an admission serum creatinine greater than 2.0 mg/dL was 42 per cent (5 of 12) compared with 3 per cent (2 of 32) for those 2.0 mg/dL or less (OR, 10.7; CI, 1.7 to 67; P = 0.01). Morbidity and mortality in geriatric patients undergoing emergency surgery remains high with the most significant predictor of mortality being the presence of renal insufficiency on admission.

The risks and costs of transfusion are a great concern in the area of pediatric spine surgery, because it is a blood-intensive procedure with a high risk for transfusion. Therefore, determining the predictors of transfusion in this patient population is an important first step and has the potential to improve upon the current approaches to reducing transfusion rates. In this study, we reveal several predictors of transfusion in a pediatric patient population undergoing spine surgery. In turn, we present a general rule of thumb ("rule of two's") for gauging transfusion risk, thus enhancing the surgeon's approach to avoiding transfusion in certain clinical scenarios. This study was conducted to determine the main factors of transfusion in a population of pediatric patients undergoing scoliosis surgery. The goal was to present an algorithm for quantifying the true risk of transfusion for various patient groups that would highlight patients "at high risk" for transfusion. This is especially important in light of the various risks associated with undergoing a transfusion, as well as the costs involved in maintaining and disposing of exogenous blood materials. This is a retrospective review of a group of children who underwent scoliosis surgery between 1988 and 1995 at an academic institution. A total of 290 patients were analyzed in this study, of which 63 were transfused and 227 were not. No outcomes measures were used in this study. A retrospective review of 290 patients presenting to our institution for scoliosis surgery was conducted, with a focus on socioclinical data related to transfusion risk. Univariate analysis and logistic regression were used to quantify the determinants of transfusion risk. Univariate analysis identified many factors that were associated with the risk of transfusion. However, it is clear that several of these factors are dependent on each other, obscuring the true issues driving transfusion need. We used multivariate analysis to control for

Respiratory support of neonates during and following laser surgery for retinopathy of prematurity (ROP) is commonly accomplished using endotracheal intubation and mechanical ventilation. However, most patients undergoing ROP surgery have been weaned off mechanical ventilation days or weeks before the surgery. When they are electively re-intubated for ROP surgery, it can be difficult to extubate them postoperatively. One of the three level III neonatal intensive care units (NICUs) in the Intermountain Healthcare system initiated a program of using nasopharyngeal prongs, rather than endotracheal intubation, for respiratory support during ROP surgery. We performed an historic cohort analysis of all neonates undergoing ROP surgery during their NICU stay at the three level III NICU's between 1 January 2002 and 31 March 2006. Data collected included birth weight, gestational age at delivery and corrected gestational age at ROP surgery, whether or not they were intubated in the days immediately preceding the ROP surgery, whether or not they were electively intubated for the ROP surgery, the respiratory modality used during and the 3 days following ROP surgery, and all blood gas determinations and respiratory charges during this period. Fifty-four patients underwent ROP surgery during this period. All 23 from NICUs 'A' and 'B' had endotracheal intubation for surgery, while in NICU 'C' 24 were managed using nasopharyngeal prongs. The birth weights of those intubated for surgery (661+/-180 g, mean+/-s.d.) were similar to those not intubated (732+/-180 g). Similarly, the gestational age at birth did not differ between those intubated for surgery (25.2+/-1.3 week) and those not (25.6+/-2.1 week). The day following surgery, 77% (23/30) of those who had been intubated for surgery remained intubated and on mechanical ventilation, whereas only one (4%) of those not intubated for surgery was intubated in the postoperative period (P<0.001). On day 3 following surgery, 50% (15/30) of

Several authors have suggested that right ventricular dysfunction (RVd) may contribute to renal dysfunction in nonsurgical patients. We tested the hypothesis that RVd diagnosed immediately after cardiac surgery may be associated with subsequent development of renal dysfunction and tried to identify the possible mechanisms. A single-centre, prospective observational study. Amiens University Hospital, France. All adult patients undergoing cardiac surgery were considered eligible for participation. Patients who had undergone pulmonary or tricuspid valve surgery, repeat surgery or who underwent immediate postoperative renal replacement therapy were excluded. Data from 74 patients were analysed. Left ventricular and right ventricular function were assessed before surgery and on admission to ICU by transthoracic echocardiography (TTE): left ventricular and right ventricular ejection fractions (LVEF/RVEF), tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (Sr(t)) and right ventricular dilatation. RVd was defined as values in the lowest quartile of at least two echocardiographic variables. Renal dysfunction was defined as an increase in serum creatinine concentration (sCr) on postoperative day 1. All right ventricular TTE variables decreased (P < 0.05) after surgery: RVEF from 50% (49 to 60) to 40% (35 to 50); TAPSE from 22.3 mm (19.4 to 25.3) to 12.2 mm (8.8 to 14.8); and Sr(t) from 15.0 cm s(-1) (12.0 to 18.0) to 8.1 cm s(-1) (6.3 to 9.2). Fourteen (19%) patients had right ventricular dilatation and RVd was present in 23 (31%) patients. Forty patients had a positive variation in sCr. In multivariate analysis, patients with RVd had an odds ratio (OR) of 12.7 [95% confidence interval (95% CI) 2.6 to 63.4, P = 0.02] for development of renal dysfunction. Renal dysfunction was associated with increased central venous pressure but was not associated with cardiac index (CI). These results suggest that early postoperative RVd is associated

Postoperative complications have been identified as an important and potentially preventable cause of increased hospital costs. While older adults are at increased risk of experiencing complications and other adverse events, very little research has specifically examined how these events impact inpatient costs. We sought to examine the association between postoperative complications, hospital mortality and loss of independence and direct inpatient health care costs in patients 70 years or older who underwent nonelective abdominal surgery. We prospectively enrolled consecutive patients 70 years or older who underwent nonelective abdominal surgery between July 1, 2011, and Sept. 30, 2012. Detailed patient-level data were collected regarding demographics, diagnosis, treatment and outcomes. Patient-level resource tracking was used to calculate direct hospital costs (2012 $CDN). We examined the association between complications, hospital mortality and loss of independence cost using multiple linear regression. During the study period 212 patients underwent surgery. Overall, 51.9% of patients experienced a nonfatal complication (32.5% minor and 19.4% major), 6.6% died in hospital and 22.6% experienced a loss of independence. On multivariate analysis nonfatal complications (p < 0.001), hospital mortality (p = 0.021) and loss of independence at discharge (p < 0.001) were independently associated with health care costs. These adverse events respectively accounted for 30%, 4% and 10% of the total costs of hospital care. Adverse events were common after abdominal surgery in older adults and accounted for 44% of overall costs. This represents a substantial opportunity for better patient outcomes and cost savings with quality improvement strategies tailored to the needs of this high-risk surgical population.

A number of 'proof-of-concept' trials suggest that remote ischaemic preconditioning (RIPC) reduces surrogate markers of end-organ injury in patients undergoing major cardiovascular surgery. To date, few studies have involved hard clinical outcomes as primary end-points. Randomised clinical trials of RIPC in major adult cardiovascular surgery were identified by a systematic review of electronic abstract databases, conference proceedings and article reference lists. Clinical end-points were extracted from trial reports. In addition, trial principal investigators provided unpublished clinical outcome data. In total, 23 trials of RIPC in 2200 patients undergoing major adult cardiovascular surgery were identified. RIPC did not have a significant effect on clinical end-points (death, peri-operative myocardial infarction (MI), renal failure, stroke, mesenteric ischaemia, hospital or critical care length of stay). Pooled data from pilot trials cannot confirm that RIPC has any significant effect on clinically relevant end-points. Heterogeneity in study inclusion and exclusion criteria and in the type of preconditioning stimulus limits the potential for extrapolation at present. An effort must be made to clarify the optimal preconditioning stimulus. Following this, large-scale trials in a range of patient populations are required to ascertain the role of this simple, cost-effective intervention in routine practice.

2017-12-01

Delirium is a temporary mental disorder that occurs frequently among hospitalized patients. In this study we sought to develop a user-friendly scorecard based on perioperative features to identify patients at risk of developing agitated delirium after cardiac surgery. Retrospective analysis was performed on adult patients undergoing cardiac surgery in a single center. A parsimonious predictive model was created, with subsequent internal validation. Then a simple scorecard was developed that can be used to predict the probability of agitated delirium. Among the 5584 patients who met the study criteria, 614 (11.4%) developed postoperative agitated delirium. Independent predictors of postoperative agitated delirium were age, male gender, history of cerebrovascular disease, procedure other than isolated Coronary Arteries Bypass Surgery, transfusion of blood products within the first 48h, mechanical ventilation for >24h, length of stay in the Intensive Care Unit. The scorecard stratified patients into 4 categories at risk of postoperative agitated delirium ranging from <5% to >30%. Using a large cohort of adult patient's undergoing cardiac surgery, a user-friendly scorecard was developed and validated, which will facilitate the implementation of timely interventions to mitigate adverse effects of agitated delirium in this high risk population.

Ambispective cohort review. To examine the effects of early mobilization on patient outcomes, complications profile, and 30-day readmission rates. Prolonged immobilization after surgery can result in functional decline and an increased risk of hospital-associated complications. We conducted an ambispective study of 125 elderly patients (>65 years) undergoing elective spinal surgery for correction of adult degenerative scoliosis. We identified all unplanned readmissions within 30 days of discharge. Unplanned readmissions were defined to have occurred as a result of either a surgical or a nonsurgical complication. "Days of immobility" was defined as the number of days until a patient moved out of bed beyond a chair. Patients in the top and bottom quartiles were dichotomized into "early ambulators" and "late ambulators", respectively. Early ambulators were ambulatory within 24 hours of surgery, whereas late ambulators were ambulatory at a minimum of 48 hours after surgery. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between early ambulators and late ambulators. Baseline characteristics were similar between both cohorts. Compared with patients with a longer duration of immobility (i.e., late ambulators), the prevalence of at least one perioperative complication was significantly lower in the early ambulators cohort (30% vs. 54%, P = 0.06). The length of inhospital stay was 34% shorter in the early ambulators cohort (5.33 days vs. 8.11 days, P = 0.01). Functional independence was superior in the early ambulators cohort, with the majority of patients discharged directly home after surgery compared with late ambulators (71.2% vs. 22.0%, P = 0.01). Early ambulation after surgery significantly reduces the incidence of perioperative complications, shortens duration of inhospital stay, and contributes to improved perioperative functional status in elderly patients. Even a delay of 24 hours to ambulation is

Advances in early management of congenital heart disease (CHD) have led to an exponential growth in adults with CHD (ACHD). Many of these patients require cardiac surgery. This study sought to examine outcome and its predictors for ACHD cardiac surgery. This is an observational cohort study of prospectively collected data on 1090 consecutive adult patients with CHD, undergoing 1130 cardiac operations for CHD at the Royal Brompton Hospital between 2002 and 2011. Early mortality was the primary outcome measure. Midterm to longer-term survival, cumulative incidence of reoperation, other interventions and/or new-onset arrhythmia were secondary outcome measures. Predictors of early/total mortality were identified. Age at surgery was 35±15 years, 53% male, 52.3% were in New York Heart Association (NYHA) class I, 37.2% in class II and 10.4% in class III/IV. Early mortality was 1.77% with independent predictors NYHA class ≥ III, tricuspid annular plane systolic excursion (TAPSE) <15 mm and female gender. Over a mean follow-up of 2.8±2.6 years, 46 patients died. Baseline predictors of total mortality were NYHA class ≥ III, TAPSE <15 mm and non-elective surgery. The number of sternotomies was not independently associated with neither early nor total mortality. At 10 years, probability of survival was 94%. NYHA class among survivors was significantly improved, compared with baseline. Contemporary cardiac surgery for ACHD performed at a single, tertiary reference centre with a multidisciplinary approach is associated with low mortality and improved functional status. Also, our findings emphasise the point that surgery should not be delayed because of reluctance to reoperate only. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To predict who will undergo midurethral sling surgery (surgery) after initial pelvic floor muscle training (physiotherapy) for stress urinary incontinence in women. This was a cohort study including women with moderate to severe stress incontinence who were allocated to the physiotherapy arm from a previously reported multicentre trial comparing initial surgery or initial physiotherapy in treating stress urinary incontinence. Crossover to surgery was allowed. Data from 198/230 women who were randomized to physiotherapy was available for analysis, of whom 97/198 (49 %) crossed over to surgery. Prognostic factors for undergoing surgery after physiotherapy were age <55 years at baseline (OR 2.87; 95 % CI 1.30-6.32), higher educational level (OR 3.28; 95 % CI 0.80-13.47), severe incontinence at baseline according to the Sandvik index (OR 1.77; 95 % CI 0.95-3.29) and Urogenital Distress Inventory; incontinence domain score (OR 1.03; per point; 95 % CI 1.01-1.65). Furthermore, there was interaction between age <55 years and higher educational level (OR 0.09; 95 % CI 0.02-0.46). Using these variables we constructed a prediction rule to estimate the risk of surgery after initial physiotherapy. In women with moderate to severe stress incontinence, individual prediction for surgery after initial physiotherapy is possible, thus enabling shared decision making for the choice between initial conservative or invasive management of stress urinary incontinence.

Cross-sectional study. To investigate the factors associated with work ability in patients undergoing surgery for cervical radiculopathy. Surgery is a common treatment of cervical radiculopathy in people of working age. However, few studies have investigated the impact on the work ability of these patients. Patients undergoing surgery for cervical radiculopathy (n = 201) were recruited from spine centers in Sweden to complete a battery of questionnaires and physical measures the day before surgery. The associations between various individual, psychological, and work-related factors and self-reported work ability were investigated by Spearman rank correlation coefficient, multivariate linear regression, and forward stepwise regression analyses. Factors that were significant (P < 0.05) in each statistical analysis were entered into the successive analysis to reveal the factors most related to work ability. Work ability was assessed using the Work Ability Index. The mean Work Ability Index score was 28 (SD, 9.0). The forward stepwise regression analysis revealed 6 factors significantly associated with work ability, which explained 62% of the variance in the Work Ability Index. Factors highly correlated with greater work ability included greater self-efficacy in performing self-cares, lower physical load on the neck at work, greater self-reported chance of being able to work in 6 months' time, greater use of active coping strategies, lower frequency of hand weakness, and higher health-related quality of life. Psychological, work-related and individual factors were significantly associated with work ability in patients undergoing surgery for cervical radiculopathy. High self-efficacy was most associated with greater work ability. Consideration of these factors by surgeons preoperatively may provide optimal return to work outcomes after surgery. 3.

Both diabetes mellitus and hyperglycemia per se are associated with negative outcomes after cardiac surgery. In this article, we review these associations, the possible mechanisms that lead to adverse outcomes, and the epidemiology of diabetes focusing on those patients requiring cardiac surgery. We also examine outpatient and perioperative management of diabetes with the same focus. Finally, we discuss our own efforts to improve glycemic management of patients undergoing cardiac surgery at our institution, including keys to success, results of implementation, and patient safety concerns.

Clinical experience suggests that some adults who undergo bariatric surgery have children who are obese. Childhood obesity is associated with increased morbidity and mortality in later life. This study examined the prevalence of obesity among children and grandchildren (< or =12 years of age) of adult bariatric surgery patients. Patients in a prospective database of morbidly obese patients who underwent bariatric surgery between January 2004 and May 2007 were recruited by phone and in clinic. Patient demographics, body mass index (BMI) at surgery, and survey data were collected. The survey included questions regarding their child/grandchild's body habitus, weight, and height. Child obesity was defined as BMI percentile > or =95. Statistical significance was set at p < 0.05. One hundred twenty-two patients were enrolled in this study (77% women, mean BMI 49 kg/m(2)). One hundred thirty-four out of 233 children/grandchildren identified had complete data; 41% had a BMI percentile > or =95. Only 29% of these obese children were so identified by the adult respondents. Significantly more biological children/grandchildren were obese than nonbiological (p = 0.013), and significantly more biological children were obese than biological grandchildren (p = 0.027). This sample of bariatric surgery patients had a high proportion of obese preteen children/grandchildren. Obesity was most prevalent among biological children (vs. biological grandchildren and nonbiological children). Patients often did not recognize the degree of overweight in their children/grandchildren. Because families of bariatric surgery patients often include obese children, interventions aimed at all family members merit consideration.

SMOFlipid 20% is intravenous lipid emulsion (ILE) containing long-chain triglycerides (LCT), medium-chain triglycerides (MCT), olive oil, and fish oil as a mixed emulsion containing α-tocopherol. The aim was to assess the efficacy of this new ILE in gastrointestinal surgery compared with MCT/LCT. In this prospective study, 40 patients were randomized to SMOFlipid 20% or MCT/LCT (Lipovenoes 20%) group. Clinical and biochemistry data were collected. Inflammatory markers (CRP, IL-6, IL-10, TNF-α, TGF-β1) and oxidative stress (ROS and superoxide) were measured. Thirty-five patients (17 males and 18 females) with a mean age of 57 years completed the study. The patients' demographic characteristics (age, gender, height, body weight, and BMI) were similar without significant differences between groups. The increment of triglyceride on day 6 from baseline was significantly lower in SMOFlipid group than in Lipovenoes MCT/LCT group. Inflammatory markers, as well as superoxide radical and total oxygen radical were not different between groups. Despite the comparable effect on inflammatory response, because of its well-balanced fatty acid pattern, relatively low n-6:n-3 ratio, and high vitamin E content, SMOFlipid had a better triglyceride-lowering effect as compared with MCT/LCT in adult patients undergoing gastrointestinal surgery. © 2013 American Society for Parenteral and Enteral Nutrition.

To compare postoperative outcomes in children undergoing cardiac surgery during the viral respiratory season and nonviral season at our institution. This was a retrospective cohort study and secondary matched case-control analysis. The setting was an urban academic tertiary-care children's hospital. The study was comprised of all patients <18 years of age who underwent cardiac surgery at Johns Hopkins Hospital from October 2002 through September 2007. Patients were stratified by season of surgery, complexity of cardiac disease, and presence or absence of viral respiratory infection. Measurements included patient characteristics and postoperative outcomes. The primary outcome was postoperative length of stay (LOS). A total of 744 patients were included in the analysis. There was no difference in baseline characteristics or outcomes, specifically, no difference in postoperative LOS, intensive care unit (ICU) LOS, and mortality, among patients by seasons of surgery. Patients with viral respiratory illness were more likely to have longer postoperative LOS (p < 0.01) and ICU LOS (p < 0.01) compared with matched controls. We identified no difference in postoperative outcomes based on season in patients undergoing cardiac surgery. Children with viral respiratory infection have significantly worse outcomes than matched controls, strengthening the call for universal administration of influenza vaccination and palivizumab to appropriate groups. Preoperative testing for respiratory viruses should be considered during the winter months for children undergoing elective cardiac surgery.

Objective: Our objectives were to describe the preoperative mood levels and psychological readiness levels of patients undergoing primary reconstruction of the anterior cruciate ligament (ACL) and to examine differences between adolescent and adult sports medicine patients relative to psychological readiness for ACL surgery. Design and Setting: Subjects prospectively completed assessments of preoperative mood and psychological readiness for ACL surgery and rehabilitation. Subjects: The sample consisted of subjects (N = 121) involved, on average, in sport or exercise participation 12.5 h/wk (SD = 7.5); subgroups included adolescents (15–19 years of age, n = 67) and adults (≥30 years of age, n = 32). Measurements: Subjects preoperatively provided self-reported assessments of demographics, mood disturbances, 10 psychological processes of change (consciousness raising, dramatic relief, environmental reevaluation, social liberation, self-reevaluation, counterconditioning, helping relationships, reinforcement management, stimulus control, and self-liberation), decisional balance (pros versus cons of surgery), and self-efficacy. Results: Relative to the first objective, subjects reported more pros than cons associated with surgery and relatively high levels of self-efficacy. Relative to the second objective, a significant main effect was noted (Wilks lambda = 0.58, P < .01), with 42% of the variance in the dependent variables being attributed to differences among adolescents as compared with adults. Follow-up analyses indicated that, as compared with adults, adolescents reported higher mood disturbances, more pros associated with surgery, and greater use of dramatic relief, environmental reevaluation, social liberation, helping relationships, and self-liberation. Conclusions: It may be advantageous to screen patients preoperatively relative to their psychological readiness for surgery and rehabilitation. Also, adolescents reported higher preoperative mood

Assessing the neurodevelopmental status of infants with congenital heart disease before surgery provides a means of identifying those at heightened risk of developmental delay. This study aimed to investigate factors impacting clinical feasibility of pre-operative neurodevelopmental assessment of infants undergoing early open heart surgery. Infants who underwent open heart surgery prior to 4 months of age participated in this cross-sectional study. The Test of Infant Motor Performance and Prechtl's Assessment of General Movements were undertaken on infants pre-operatively. When assessments could not be undertaken, reasons were ascribed to either infant or environmental circumstances. Demographic data and Aristotle scores were compared between groups of infants who did or did not undergo assessment. Binary logistic regression was used to explore associations. A total of 60 infants participated in the study. Median gestational age was 38.78 weeks (interquartile range: 36.93-39.72). Of these infants, 37 (62%) were unable to undergo pre-operative assessment. Twenty-four (40%) could not complete assessment due to infant-related factors and 13 (22%) due to environmental-related factors. For every point increase in the Aristotle Patient-Adjusted Complexity score, the infants likelihood of being unable to undergo assessment increased by 35% (odds ratio: 0.35; 95% confidence interval: 1.03-1.77, P = 0.03). Over half of the infants undergoing open heart surgery were unable to complete pre-operative neurodevelopmental assessment. The primary reason for this was infant-related medical instability. Findings suggest further research is warranted to investigate whether the Aristotle Patient-Adjusted Complexity score might serve as an indicator to inform developmental surveillance with this medically fragile cohort. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

The administration of chloride-rich intravenous (IV) fluid and hyperchloraemia have been associated with perioperative renal injury. The aim of this study was to determine whether a comprehensive perioperative protocol for the administration of chloride-limited IV fluid would reduce perioperative renal injury in adults undergoing cardiac surgery. From February 2014 through to December 2015, all adult patients undergoing cardiac surgery within a single academic medical center received IV fluid according to the study protocol. The perioperative protocol governed all fluid administration from commencement of anesthesia through to discharge from the intensive care unit and varied over four sequential periods, each lasting 5 months. In periods 1 and 4 a chloride-rich strategy, consisting of 0.9% saline and 4% albumin, was adopted; in periods 2 and 3, a chloride-limited strategy, consisting of a buffered salt solution and 20% albumin, was used. Co-primary outcomes were peak delta serum creatinine (∆S Cr ) within 5 days after the operation and KDIGO-defined stage 2 or stage 3 acute kidney injury (AKI) within 5 days after the operation. We enrolled and analysed data from 1136 patients, with 569 patients assigned to a chloride-rich fluid strategy and 567 to a chloride-limited one. Compared with a chloride-limited strategy and adjusted for prespecified covariates, there was no association between a chloride-rich perioperative fluid strategy and either peak ∆S Cr , transformed to satisfy the assumptions of multivariable linear regression [regression coefficient 0.03, 95% confidence interval (CI) -0.03 to 0.08); p = 0.39], or stage 2 or 3 AKI (adjusted odds ratio 0.97, 95% CI 0.65-1.47; p = 0.90]. A perioperative fluid strategy to restrict IV chloride administration was not associated with an altered incidence of AKI or other metrics of renal injury in adult patients undergoing cardiac surgery.

This study aims to conduct a meta-analysis to identify and compare the effectiveness of compressive cryotherapy and cryotherapy alone for patients undergoing knee surgery. Postoperative management is an important guarantee for the success of surgery. Cryotherapy and compression are two common nursing techniques after knee surgery, and are considered to be effective for postoperative clinical symptoms such as local pain and swelling. However, no previous meta-analyses have compared the effectiveness of compressive cryotherapy and cryotherapy alone in patients undergoing knee surgery. A meta-analysis of randomized controlled trials (RCTs). We conducted a search in MEDLINE (via Pubmed, 1990-2014), EMBASE (via Elsevier, 1990-2014), Cochrane Central Register of Controlled Trials (The Cochrane Library, 1990-2014), CINAHL (1990-2014) and China National Knowledge Infrastructure (1990-2014) databases for RCTs published in English and Chinese. The primary outcome measure of interest was visual analog scale and girth measure. Finally, a meta-analysis was carried out using RevMan 5.3. Among the 593 RCTs, 10 RCTs were selected and included into this study. These studies included 522 patients who underwent knee surgery. Patients who underwent compressive cryotherapy tended to have less pain than patients who underwent cryotherapy alone at POD2 and POD3, while compressive cryotherapy had a strong tendency towards less swelling over cryotherapy alone at POD1 and POD2. However, there was no significant difference between compressive cryotherapy and cryotherapy alone at the intermediate stage of rehabilitation after knee surgery. All adverse reactions were recorded in all included RCTs. Current evidence suggests that compressive cryotherapy is beneficial to patients undergoing knee surgery at the early rehabilitation stage. At the last stage, the effectiveness of compressive cryotherapy and cryotherapy alone were found to be similar.

As the number of older adults undergoing hemodialysis increases, it is important for nurses to consider cognitive impairment as a contributing factor to non-adherence. The purpose of this exploratory study was to identify cognitive markers that nurses can use to alert them to potential problems with adherence among older adults undergoing hemodialysis. Stories of the health challenge of making lifestyle change were analyzed with a linguistic analysis software program. A standardized instrument (3MS) that measures global cognitive function was administered. Determination of adherence level was the last activity of data collection. In this sample (n=63), 39.7% of the participants had evidence of cognitive impairment (3MS score less than 80); 58.2% of the 39.7% had evidence of non-adherence. There was a significant relationship between word use and cognitive function (p < .01). Cognitive impairment is prevalent among older adults undergoing hemodialysis and words might be a proxy for recognizing this.

Objective This study was designed to compare the effectiveness of granisetron plus dexamethasone for preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery. Methods We searched the literature in the Cochrane Library, PubMed, EMBASE, and CNKI. Results In total, 11 randomized controlled trials were enrolled in this analysis. The meta-analysis showed that granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopy surgery. No significant differences in adverse reactions (dizziness and headache) were found in association with dexamethasone. Conclusion Granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopic surgery, with no difference in adverse reactions between the two groups. Granisetron alone or granisetron plus dexamethasone can be used to prevent PONV in patients undergoing laparoscopic surgery. PMID:28436248

It may be difficult to distinguish between adults with type 1 diabetes and type 2 diabetes by clinical assessment. In patients undergoing bariatric surgery, it is critical to correctly classify diabetes subtype to prevent adverse perioperative outcomes including diabetic ketoacidosis. This study aimed to determine whether testing for C-peptide and islet cell antibodies during preoperative evaluation for bariatric surgery could improve the classification of type 1 versus type 2 diabetes compared to clinical assessment alone. This is a retrospective analysis of the Improving Diabetes through Lifestyle and Surgery trial, which randomized patients with clinically diagnosed type 2 diabetes and BMI 30-40 kg/m 2 to medical weight loss or bariatric surgery; one participant was discovered to have type 1 diabetes after experiencing postoperative diabetic ketoacidosis. Using blood samples collected prior to study interventions, we measured islet cell antibodies and fasting/meal-stimulated C-peptide in all participants. The participant with type 1 diabetes was similar to the 11 participants with type 2 diabetes in age at diagnosis, adiposity, and glycemic control but had the lowest C-peptide levels. Among insulin-treated participants, fasting and stimulated C-peptide correlated strongly with the C-peptide area-under-the-curve on mixed meal tolerance testing (R = 0.86 and 0.88, respectively). Three participants, including the one with type 1 diabetes, were islet cell antibody positive. Clinical characteristics did not correctly identify type 1 diabetes in this study. Preoperative C-peptide testing may improve diabetes classification in patients undergoing bariatric surgery; further research is needed to define the optimal C-peptide thresholds.

Nursing students' perceptions of clients undergoing elective cosmetic surgery.

Aesthetic obsession is commonplace in current society. Supermarket a isles dedicated to beauty products, makeup, and anti-aging creams seem to expand daily. Television and publications flood the public with messages of what constitutes beauty and how to achieve the ideal. Surgical alteration of the body is swiftly becoming a form of self-care technique along with other heath-promoting behavior. Since 2003, the general acceptance of plastic surgery among all Americans surpassed 50% (American Society for Aesthetic Plastic Surgery, 2003). Elective cosmetic surgical procedures have increased by an astounding 444% since 1997 (American Society of Plastic Surgeons, 2006). This quest for body satisfaction based on modern cultural norms increases the public's need for accurate information and understanding from those in the healthcare profession. Despite a transformation in the general population's conception of cosmetic surgery and its clients, stigma still lies in many individuals, including those in the healthcare profession. As this progressively growing patient population emerges, many in healthcare question their attitudes toward plastic surgery and the patients receiving aesthetic operations. With clients undergoing plastic surgery becoming increasingly visible within the healthcare system, some unique aspects of patient care must be addressed.

Screening laboratory studies for bleeding disorders are of little predictive value for operative bleeding risk in adults. Predicting perioperative bleeding in pediatric patients is particularly difficult as younger patients often have not had significant hemostatic challenges. This issue is distinctly important for high bleeding risk surgeries, such as major spinal procedures. The aim of this study was to determine if the score of a detailed bleeding questionnaire (BQ) correlated with surgical bleeding in pediatric patients undergoing major spinal surgery. A total of 220 consecutive pediatric patients (mean age 14.2years) undergoing major spinal surgery were administered the BQ preoperatively, as well as having routine screening laboratory studies (i.e., PT, aPTT, PFA) drawn. A retrospective analysis was conducted to determine if there was a correlation between either the results of the BQ and/or laboratory studies with operative outcomes. A BQ score>2 showed a strong positive correlation with intraoperative bleeding based on both univariate and multivariate analyses. In contrast, abnormalities in screening laboratory studies showed no significant correlation with operative bleeding outcomes. Relying on screening laboratory studies alone is inadequate. The BQ used here correlated with increased intraoperative hemorrhage, suggesting this tool may be useful for assessing pediatric surgical bleeding risk, and may also be useful in identifying a subset of patients with a very low bleeding risk that may not require laboratory screening.

2009-01-01

Previous studies have shown that hyperglycaemia is associated with postoperative complications in cardiac surgical patients. Conversely, well-controlled glucose levels are said to reduce major infectious complications in diabetic patients. The purpose of this clinical audit was to evaluate the blood glucose levels of diabetic patients undergoing cardiac surgery and to determine the effectiveness of postoperative glycaemic control. A group of 150 patients from a large Irish cardiac surgery centre was selected by convenience sampling. An audit tool was designed to capture the patients' blood glucose levels, treatment regimes and postoperative complications. The findings showed major variations between 'high', 'good' and 'borderline' blood glucose levels in the pre- and postoperative phase. Although blood glucose testing practices seemed inconsistent, mean levels measured 'borderline'. Furthermore, the treatment regimes varied greatly and suggest a lack of consensus regarding the management of postoperative hyperglycaemia. A total of 52% (n = 78) patients developed 114 complications with a level of 21.4% (n = 32) postoperative wound infections. The findings from this audit highlight the importance of regular blood glucose testing to enable early detection of hyperglycaemia and timely initiation of appropriate treatments regimes for diabetic patients undergoing cardiac surgery. Findings also show that hyperglycaemia derangement may make a difference in the recovery phase. While patients will benefit from lesser wound infections, hospitals might save costs involved with treating postoperative complications. More consistent blood glucose testing might be achieved through the use of evidence-based protocols. However, the education of staff is as important as it develops knowledge on the complex metabolic interactions of diabetic patients undergoing cardiac surgery. While this means investing in staff education and policy development, costs for daily care and expensive

Of the 200 million adults worldwide who undergo noncardiac surgery each year, more than 1 million will die within 30 days. To determine the relationship between the peak fourth-generation troponin T (TnT) measurement in the first 3 days after noncardiac surgery and 30-day mortality. A prospective, international cohort study that enrolled patients from August 6, 2007, to January 11, 2011. Eligible patients were aged 45 years and older and required at least an overnight hospital admission after having noncardiac surgery. Patients' TnT levels were measured 6 to 12 hours after surgery and on days 1, 2, and 3 after surgery. We undertook Cox regression analysis in which the dependent variable was mortality until 30 days after surgery, and the independent variables included 24 preoperative variables. We repeated this analysis, adding the peak TnT measurement during the first 3 postoperative days as an independent variable and used a minimum P value approach to determine if there were TnT thresholds that independently altered patients' risk of death. A total of 15,133 patients were included in this study. The 30-day mortality rate was 1.9% (95% CI, 1.7%-2.1%). Multivariable analysis demonstrated that peak TnT values of at least 0.02 ng/mL, occurring in 11.6% of patients, were associated with higher 30-day mortality compared with the reference group (peak TnT ≤ 0.01 ng/mL): peak TnT of 0.02 ng/mL (adjusted hazard ratio [aHR], 2.41; 95% CI, 1.33-3.77); 0.03 to 0.29 ng/mL (aHR, 5.00; 95% CI, 3.72-6.76); and 0.30 ng/mL or greater (aHR, 10.48; 95% CI, 6.25-16.62). Patients with a peak TnT value of 0.01 ng/mL or less, 0.02, 0.03-0.29, and 0.30 or greater had 30-day mortality rates of 1.0%, 4.0%, 9.3%, and 16.9%, respectively. Peak TnT measurement added incremental prognostic value to discriminate those likely to die within 30 days for the model with peak TnT measurement vs without (C index = 0.85 vs 0.81; difference, 0.4; 95% CI, 0.2-0.5; P < .001 for difference between C

Obesity is associated with greater rates of surgical complications. To address these complications after outpatient plastic surgery, obese patients may seek care in the emergency department and potentially require admission to the hospital, which could result in greater health care charges. The purpose of this study was to determine the relationship of obesity, postdischarge hospital-based acute care, and hospital charges within 30 days of outpatient plastic surgery. From state ambulatory surgery center databases in four states, all discharges for adult patients who underwent liposuction, abdominoplasty, breast reduction, and blepharoplasty were identified. Patients were grouped by the presence or absence of obesity. Multivariable regression models were used to compare the frequency of hospital-based acute care, serious adverse events, and hospital charges within 30 days between groups while controlling for confounding variables. The final sample included 47,741 discharges, with 2052 of these discharges (4.3 percent) being obese. Obese patients more frequently had a hospital-based acute care encounter [7.3 percent versus 3.9 percent; adjusted OR, 1.35 (95% CI,1.13 to 1.61)] or serious adverse event [3.2 percent versus 0.9 percent; adjusted OR, 1.73 (95% CI, 1.30 to 2.29)] within 30 days of surgery. Obese patients had adjusted hospital charges that were, on average, $3917, $7412, and $7059 greater (p < 0.01) than those of nonobese patients after liposuction, abdominoplasty, and breast reduction, respectively. Obese patients who undergo common outpatient plastic surgery procedures incur substantially greater health care charges, in part attributable to more frequent adverse events and hospital-based health care within 30 days of surgery.

Navigated transcranial magnetic stimulation (nTMS) is becoming increasingly popular in noninvasive preoperative language mapping, as its results correlate well enough with those obtained by direct cortical stimulation (DCS) during awake surgery in adult patients with tumor. Reports in the context of epilepsy surgery or extraoperative DCS in adults are, however, sparse, and validation of nTMS with DCS in children is lacking. Furthermore, little is known about the risk of inducing epileptic seizures with nTMS in pediatric epilepsy patients. We provide the largest validation study to date in an epilepsy surgery population. We compared language mapping with nTMS and extraoperative DCS in 20 epilepsy surgery patients (age range 9-32 years; 14 children and adolescents). In comparison with DCS, sensitivity of nTMS was 68%, specificity 76%, positive predictive value 27%, and negative predictive value 95%. Age, location of ictal-onset zone near or within DCS-mapped language areas or severity of cognitive deficits had no significant effect on these values. None of our patients had seizures during nTMS. Our study suggests that nTMS language mapping is clinically useful and safe in epilepsy surgery patients, including school-aged children and patients with extensive cognitive dysfunction. Similar to in tumor surgery, mapping results in the frontal region are most reliable. False negative findings may be slightly more likely in epilepsy than in tumor surgery patients. Mapping results should always be verified by other methods in individual patients.

Although there have been meta-analyses of the effects of exercise prehabilitation on patients undergoing colorectal surgery, little is known about the effects of nutrition-only (oral nutritional supplements and/or counseling) and multi-modal (oral nutritional supplements and/or counseling with exercise) prehabilitation on clinical outcomes and patient function after surgery. We performed a systemic review and meta-analysis to determine the individual and combined effects of nutrition-only and multi-modal prehabilitation, compared with no prehabilitation (control), on outcomes of patients undergoing colorectal resection. We searched MEDLINE, EMBASE, CINAHL, CENTRAL, and ProQuest for cohort and randomized controlled studies of adults awaiting colorectal surgery who received at least 7 days of oral nutrition supplements and/or nutrition counselling with or without exercise. We performed a random effects meta-analysis to estimate the pooled risk ratio for categorical data and the weighted mean difference for continuous variables. The primary outcome was length of hospital stay; the secondary outcome was recovery of functional capacity, based on results of a 6-minute walk test. We identified 9 studies (5 randomized controlled studies and 4 cohort studies) comprising 914 patients undergoing colorectal surgery (438 received prehabilitation and 476 served as controls). Receipt of any prehabilitation significantly reduced days spent in hospital compared with controls (weighted mean difference of length of hospital stay, -2.2 days; 95% CI, -3.5 days to -0.9 days). Only 3 studies reported functional outcomes but could not be pooled due to methodological heterogeneity. In the individual studies, multimodal prehabilitation significantly improved results of the 6-minute walk test at 4 and 8 weeks after surgery compared with standard enhanced recovery pathway care, and at 8 weeks compared with standard enhanced recovery pathway care with added rehabilitation.

The aim of this study was to determine the influence of music on anxiety levels and physiologic parameters in women undergoing gynecologic surgery. This study employed a pre- and posttest experimental design with nonrandom assignment. Ninety-seven women undergoing gynecologic surgery were included in the study, where 49 were allocated to the control group (nonmusic group) and 48 were assigned to the experimental group (music group). Preoperative anxiety was measured using the State Trait Anxiety Inventory (STAI) while noninvasive instruments were used in measuring the patients' physiologic parameters (blood pressure [BP], pulse [P], and respiration [R]) at two time periods. Women allocated in the experimental group had lower STAI scores (t = 17.41, p < .05), systolic (t = 6.45, p < .05) and diastolic (t = 2.80, p < .006) BP, and P rate (PR; t = 7.32, p < .05) than in the control group. This study provides empirical evidence to support the use of music during the preoperative period in reducing anxiety and unpleasant symptoms in women undergoing gynecologic surgery. © The Author(s) 2014.

Approximately 30% of patients undergoing elective general surgery smoke cigarettes. The association between smoking status and hospital costs in general surgery patients is unknown. The objectives of this study were to compare total inpatient costs in current smokers, former smokers, and never smokers undergoing general surgical procedures in Veterans Affairs (VA) hospitals; and to determine whether the relationship between smoking and cost is mediated by postoperative complications. Patients undergoing general surgery during the period of October 1, 2005 to September 30, 2006 were identified in the VA Surgical Quality Improvement Program (VASQIP) data set. Inpatient costs were extracted from the VA Decision Support System (DSS). Relative surgical costs (incurred during index hospitalization and within 30 days of operation) for current and former smokers relative to never smokers, and possible mediators of the association between smoking status and cost were estimated using generalized linear regression models. Models were adjusted for preoperative and operative variables, accounting for clustering of costs at the hospital level. Of the 14,853 general surgical patients, 34% were current smokers, 39% were former smokers, and 27% were never smokers. After controlling for patient covariates, current smokers had significantly higher costs compared with never smokers: relative cost was 1.04 (95% Cl 1.00 to 1.07; p = 0.04); relative costs for former smokers did not differ significantly from those of never smokers: 1.02 (95% Cl 0.99 to 1.06; p = 0.14). The relationship between smoking and hospital costs for current smokers was partially mediated by postoperative respiratory complications. These findings complement emerging evidence recommending effective smoking cessation programs in general surgical patients and provide an estimate of the potential savings that could be accrued during the preoperative period.

OBJECTIVE To determine factors affecting race speed in Swedish Standardbred horses undergoing surgery of the carpal flexor sheath (CFS), to investigate whether preoperative racing speed was associated with specific intraoperative findings and whether horses returned to racing, and to compare the performance of horses undergoing surgery of the CFS with that of age- and sex-matched control horses. ANIMALS 149 Swedish Standardbred trotters undergoing surgery of the CFS and 274 age- and sex-matched control horses. PROCEDURES Medical records of CFS horses were examined. Racing data for CFS and control horses were retrieved from official online records. Generalizing estimating equations were used to examine overall and presurgery racing speeds and the association of preoperative clinical and intraoperative findings with preoperative and postoperative speeds. Multivariable regression analysis was used to examine career earnings and number of career races. Kaplan-Meier survival analysis was used to compare career longevity between CFS and control horses. RESULTS CFS horses were significantly faster than control horses. The CFS horses that raced before surgery were slower as they approached the surgery date, but race speed increased after surgery. There were 124 of 137 (90.5%) CFS horses that raced after surgery. No intrathecal pathological findings were significantly associated with preoperative racing speed. Career longevity did not differ between CFS and control horses. CONCLUSIONS AND CLINICAL RELEVANCE Horses undergoing surgery of the CFS had a good prognosis to return to racing after surgery. Racing careers of horses undergoing surgery of the CFS were not significantly different from racing careers of control horses.

Speckle tracking, when combined with 3-dimensional (3D) left ventricular ejection fraction, might prove to be a more sensitive marker for postoperative ventricular dysfunction. This study investigated early outcomes in a cohort of patients with left ventricular dysfunction undergoing cardiac surgery. Prospective, blinded, observational study. University hospital; single institution. The study comprised 73 adult patients with left ventricular ejection fraction <50% undergoing cardiac surgery using cardiopulmonary bypass. Routine transesophageal echocardiography before and after bypass. Global longitudinal strain using speckle tracking and 3D left ventricular ejection fraction were computed using transesophageal echocardiography. Mean prebypass global longitudinal strain and 3D left ventricle ejection fraction were significantly lower in patients with postoperative low-cardiac-output syndrome compared with patients who did not develop low cardiac output (global longitudinal strain -7.5% v -10.7% and 3D left ventricular ejection fraction 29% v 39%, respectively; p < 0.0001). The cut-off value of global longitudinal strain predicting postoperative low-cardiac-output syndrome was -6%, with 95% sensitivity and 68% specificity; and 3D left ventricular ejection fraction was 19% with 98% sensitivity and 81% specificity. Preoperative left ventricular global longitudinal strain (-6%) and 3D left ventricular ejection fraction (19%) together could act as predictor of postoperative low-cardiac-output states with high sensitivity (99.9%) in patients undergoing cardiac surgery.

Temporal lobe epilepsy surgery in children versus adults: from etiologies to outcomes

PubMed Central

Lee, Yun-Jin

2013-01-01

Temporal lobe epilepsy (TLE) is the most common type of medically intractable epilepsy in adults and children, and mesial temporal sclerosis is the most common underlying cause of TLE. Unlike in the case of adults, TLE in infants and young children often has etiologies other than mesial temporal sclerosis, such as tumors, cortical dysplasia, trauma, and vascular malformations. Differences in seizure semiology have also been reported. Motor manifestations are prominent in infants and young children, but they become less obvious with increasing age. Further, automatisms tend to become increasingly complex with age. However, in childhood and especially in adolescence, the clinical manifestations are similar to those of the adult population. Selective amygdalohippocampectomy can lead to excellent postoperative seizure outcome in adults, but favorable results have been seen in children as well. Anterior temporal lobectomy may prove to be a more successful surgery than amygdalohippocampectomy in children with intractable TLE. The presence of a focal brain lesion on magnetic resonance imaging is one of the most reliable independent predictors of a good postoperative seizure outcome. Seizure-free status is the most important predictor of improved psychosocial outcome with advanced quality of life and a lower proportion of disability among adults and children. Since the brain is more plastic during infancy and early childhood, recovery is promoted. In contrast, long epilepsy duration is an important risk factor for surgically refractory seizures. Therefore, patients with medically intractable TLE should undergo surgery as early as possible. PMID:23908666

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

To investigate if electrocardiogram (ECG) markers from routine preoperative ECGs can be used in combination with clinical data to predict new-onset postoperative atrial fibrillation (POAF) following cardiac surgery. Retrospective observational case-control study. Single-center university hospital. One hundred consecutive adult patients (50 POAF, 50 without POAF) who underwent coronary artery bypass grafting, valve surgery, or combinations. Retrospective review of medical records and registration of POAF. Clinical data and demographics were retrieved from the Western Denmark Heart Registry and patient records. Paper tracings of preoperative ECGs were collected from patient records, and ECG measurements were read by two independent readers blinded to outcome. A subset of four clinical variables (age, gender, body mass index, and type of surgery) were selected to form a multivariate clinical prediction model for POAF and five ECG variables (QRS duration, PR interval, P-wave duration, left atrial enlargement, and left ventricular hypertrophy) were used in a multivariate ECG model. Adding ECG variables to the clinical prediction model significantly improved the area under the receiver operating characteristic curve from 0.54 to 0.67 (with cross-validation). The best predictive model for POAF was a combined clinical and ECG model with the following four variables: age, PR-interval, QRS duration, and left atrial enlargement. ECG markers obtained from a routine preoperative ECG may be helpful in predicting new-onset POAF in patients undergoing cardiac surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

The authors conducted a review of randomized studies to show whether there are any increases or decreases in survival when using milrinone in patients undergoing cardiac surgery. A meta-analysis. Hospitals. Five hundred eighteen patients from 13 randomized trials. None. BioMedCentral, PubMed EMBASE, the Cochrane central register of clinical trials, and conference proceedings were searched for randomized trials that compared milrinone versus placebo or any other control in the setting of cardiac surgery that reported data on mortality. Overall analysis showed that milrinone increased perioperative mortality (13/249 [5.2%] in the milrinone group v 6/269 [2.2%] in the control arm, odds ratio [OR] = 2.67 [1.05-6.79], p for effect = 0.04, p for heterogeneity = 0.23, I(2) = 25% with 518 patients and 13 studies included). Subanalyses confirmed increased mortality with milrinone (9/84 deaths [10.7%] v 3/105 deaths [2.9%] with other drugs as control, OR = 4.19 [1.27-13.84], p = 0.02) with 189 patients and 5 studies included) but did not confirm a difference in mortality (4/165 [2.4%] in the milrinone group v 3/164 [1.8%] with placebo or nothing as control, OR = 1.27 [0.28-5.84], p = 0.76 with 329 patients and 8 studies included). This analysis suggests that milrinone might increase mortality in adult patients undergoing cardiac surgery. The effect was seen only in patients having an active inotropic drug for comparison and not in the placebo subgroup. Therefore, the question remains whether milrinone increased mortality or if the control inotropic drugs were more protective. Copyright © 2012 Elsevier Inc. All rights reserved.

Intravenous (i.v.) acetaminophen is administered during surgery for postoperative analgesia. However, little information is available on the pharmacokinetics of i.v. acetaminophen in Japanese patients undergoing surgery under general anesthesia. The study was approved by the Institutional Review Board and registered at UMIN-CTR (UMIN000013418). Patients scheduled to undergo elective surgery under general anesthesia were enrolled after obtaining written informed consent. During surgery, 1 g of i.v. acetaminophen was administered over 15, 60, or 120 min. Acetaminophen concentrations (15 or 16 samples per case) were measured at time points from 0-480 min after the start of administration (liquid chromatography-mass spectrometry/tandem mass spectrometry; limit of quantitation 0.1 μg/mL). The predictive performance of three published pharmacokinetic models was evaluated. Population pharmacokinetics were also analyzed using a nonlinear mixed-effect model based on the NONMEM program. Data from 12 patients who underwent endoscopic or lower limb procedures were analyzed (male/female = 7/5, median age 55 years, weight 63 kg). Anesthesia was maintained with remifentanil and propofol or sevoflurane. The pharmacokinetic model of i.v. acetaminophen reported by Würthwein et al. worked well. Using 185 datapoints, the pharmacokinetics of i.v. acetaminophen were described by a two-compartment model with weight as a covariate but not age, sex, or creatinine clearance. The median prediction error and median absolute prediction error of the final model were -1 and 10%, respectively. A population pharmacokinetic model of i.v. acetaminophen in Japanese patients was constructed, with performance within acceptable ranges.

Perioperative management of adult patients with a history of stroke or transient ischaemic attack undergoing elective non-cardiac surgery.

It is increasingly common for physicians and anaesthetists to be asked for advice in the medical management of surgical patients who have an incidental history of stroke or transient ischaemic attack (TIA). Advising clinicians requires an understanding of the common predictors, outcomes and management of perioperative stroke. The most important predictor of perioperative stroke is a previous history of stroke, and outcomes associated with such an event are extremely poor. The perioperative management of this patient group needs careful consideration to minimise the thrombotic risk and a comprehensive, individualised approach is crucial. Although there is literature supporting the management of such patients undergoing cardiac surgery, evidence is lacking in the setting of non-cardiac surgical intervention. This article reviews the current evidence and provides a pragmatic interpretation to inform the perioperative management of patients with a history of stroke and/or TIA presenting for elective non-cardiac surgery. © Royal College of Physicians 2016.

As the efficacy of surgical ablation for atrial fibrillation (AF) is reported to be suboptimal for patients with a giant left atrium (LA), its routine use on this population has remained controversial. We sought to evaluate the clinical outcomes of patients with a giant LA undergoing mitral valve (MV) surgery with/without the maze procedure. We identified 759 patients with a giant LA (>60 mm) and AF undergoing MV surgery from 1999 through 2012. Of these, 400 underwent MV surgery with the maze procedure (maze group), and the remainder (n=359) underwent MV surgery only (no-maze group). To reduce the impact of selection bias, propensity score analyses were performed based on 25 baseline covariates. Early death occurred in five (1.3%) and nine (2.5%) patients in the maze and the no-maze group, respectively (p=0.28). Freedom from AF at 5 years was 68.9% in the maze group and 9.6% in the no-maze group (p<0.001). After adjustment, the maze group showed a significantly lower risk of death (HR, 0.65; 95% CI 0.44 to 0.98; p=0.038), thromboembolic events (HR, 0.23; 95% CI 0.09 to 0.58; p=0.002) and composite adverse outcomes (death, congestive heart failure and valve-related complications; HR, 0.55; 95% CI 0.42 to 0.71; p<0.001) than the no-maze group. In subgroup analyses, MV surgery with the maze procedure resulted in higher survival and event-free survival in most risk subgroups than without the maze procedure. The concomitant maze procedure improved postoperative rhythm status, clinical outcomes and cardiac functions in patients with a giant LA undergoing MV surgery. This study indicates that the patients with a giant LA undergoing MV surgery may benefit from an addition of the maze procedure. Published by the BMJ Publishing Group Limited.

Complications of adult spinal deformity surgery are problematic in osteoporotic individuals. We compared outcomes between Japanese patients treated perioperatively with teriparatide vs. low-dose bisphosphonates. Fifty-eight osteoporotic adult Japanese female patients were enrolled and assigned to perioperative teriparatide (33 patients) and bisphosphonate (25 patients) groups in non-blinded fashion. Pre- and post-operative X-ray and computed tomography imaging were used to assess outcome, and rates were compared between the groups and according to age. Pain scores and Oswestry Disability Indices (ODI) were calculated before and 2 years after surgery. Adjacent vertebral fractures and implant failure, fusion failure, and poor pain and ODI outcomes were significantly more common in the bisphosphonates group than the teriparatide group. Perioperative administration of teriparatide is more effective than that of low-dose bisphosphonates in preventing complications and maintaining fusion rates in osteoporotic Japanese females with spinal deformities undergoing surgery.

Parents feel fear and anxiety before surgery is performed on their child, and those feelings could obstruct their preparation for the surgery. Preoperative information could relieve those feelings. To determine the preoperative information needs of parents of children undergoing elective surgery. A study was conducted on the parents of children who underwent elective surgery. Demographic data of parents were recorded. Preoperative information received or would like to have received was assessed in terms of contents, methods, opportunity, place and informant. Descriptive statistics were used. Thirteen hundred parents were surveyed. More than 80% of them want preoperative information about anaesthesia, surgery, preoperative fasting, drugs and anaesthetic complications, monitoring, intravenous line management, pain treatment, postoperative feeding, anxiety control, hospitalisation room, recovery room, and entertainment in recovery room. Most want to be informed verbally, one to two weeks in advance and not on the same day of surgery. The informant should be the surgeon and in his office. In addition, they want information through leaflets, videos and simulation workshops, or guided tours. Parents need complete preoperative information about anesthesia, surgery and postoperative care, received verbally and in advance. Copyright © 2015 Sociedad Chilena de Pediatría.

Some observational studies have reported that transfusion of red-cell units that have been stored for more than 2 to 3 weeks is associated with serious, even fatal, adverse events. Patients undergoing cardiac surgery may be especially vulnerable to the adverse effects of transfusion. We conducted a randomized trial at multiple sites from 2010 to 2014. Participants 12 years of age or older who were undergoing complex cardiac surgery and were likely to undergo transfusion of red cells were randomly assigned to receive leukocyte-reduced red cells stored for 10 days or less (shorter-term storage group) or for 21 days or more (longer-term storage group) for all intraoperative and postoperative transfusions. The primary outcome was the change in Multiple Organ Dysfunction Score (MODS; range, 0 to 24, with higher scores indicating more severe organ dysfunction) from the preoperative score to the highest composite score through day 7 or the time of death or discharge. The median storage time of red-cell units provided to the 1098 participants who received red-cell transfusion was 7 days in the shorter-term storage group and 28 days in the longer-term storage group. The mean change in MODS was an increase of 8.5 and 8.7 points, respectively (95% confidence interval for the difference, -0.6 to 0.3; P=0.44). The 7-day mortality was 2.8% in the shorter-term storage group and 2.0% in the longer-term storage group (P=0.43); 28-day mortality was 4.4% and 5.3%, respectively (P=0.57). Adverse events did not differ significantly between groups except that hyperbilirubinemia was more common in the longer-term storage group. The duration of red-cell storage was not associated with significant differences in the change in MODS. We did not find that the transfusion of red cells stored for 10 days or less was superior to the transfusion of red cells stored for 21 days or more among patients 12 years of age or older who were undergoing complex cardiac surgery.

Serotonin (5-HT3) receptor antagonists are a class of antiemetic medications often used to prevent nausea and vomiting among patients undergoing chemotherapy, radiotherapy or surgery. However, recent studies suggest that these agents might be associated with increased cardiac harm. To examine this further, we are proposing to conduct a systematic review and network meta-analysis on the comparative safety of 5-HT3 receptor antagonists among patients undergoing chemotherapy or surgery. Studies reporting one or more safety outcomes of interest for 5-HT3 receptor antagonists compared with each other, placebo, and/or other anti-emetic agents (for example, benzamides, phenothiazines, butyrophenones, antihistamines, and anticholinergics) among children and adult patients undergoing surgery or chemotherapy will be included. Our primary outcome of interest is arrhythmia. Our secondary outcomes include cardiac death, QT prolongation, PR prolongation, all-cause mortality, nausea, and vomiting. We will include experimental studies, quasi-experimental studies (namely controlled before-after and interrupted time series), and observational studies (namely cohort studies). We will not limit inclusion by publication status, time period, duration of follow-up or language of dissemination.Electronic databases (for example, MEDLINE, EMBASE) will be searched from inception onwards. These main searches will be supplemented by searching for difficult to locate and unpublished studies, such as dissertations, and governmental reports. The eligibility criteria will be pilot-tested and subsequently used to screen the literature search results by two reviewers in duplicate. A similar process will be followed for full-text screening, data abstraction, and risk of bias/methodological quality appraisal. The Cochrane Risk of Bias tool will be used to appraise experimental and quasi-experimental studies, and cohort studies will be assessed using the Newcastle Ottawa Scale. If the data allows

Few investigations preoperatively are important for low-risk patients. This study was designed to determine the level of compliance with preoperative investigation guidelines for ASA I patients undergoing elective surgery. Secondary objectives included the following: to identify common inappropriate investigations, to evaluate the impact of abnormal testing on patient management, to determine factors affecting noncompliant tests, and to estimate unnecessary expenditure. This retrospective study was conducted on adult patients over a one-year period. The institute's guidelines recommend tests according to the patients' age groups: a complete blood count (CBC) for those patients aged 18-45; CBC, chest radiograph (CXR) and electrocardiography (ECG) for those aged 46-60; and CBC, CXR, ECG, electrolytes, blood glucose, blood urea nitrogen (BUN), and creatinine (Cr) for patients aged 61-65. The medical records of 1,496 patients were reviewed. Compliant testing was found in only 12.1% (95% CI, 10.5-13.9). BUN and Cr testings were the most frequently overprescribed tests. Overinvestigations tended to be performed on major surgery and younger patients. Overall, overinvestigation incurred an estimated cost of US 200,000 dollars during the study period. The need to utilize the institution's preoperative guidelines should be emphasized in order to decrease unnecessary testing and the consequential financial burden.

Symptom distress remains a significant health problem among older adults with cancer following surgery. Understanding factors influencing older adults' symptom distress may lead to early identification and interventions, decreasing morbidity and improving outcomes. We conducted this study to identify factors associated with symptom distress following surgery among 326 community-residing patients 65 years or older with a diagnosis of thoracic, digestive, gynecologic, and genitourinary cancers. This secondary analysis used combined subsets of data from 5 nurse-directed intervention clinical trials targeting patients after surgery at academic cancer centers in northwest and northeastern United States. Symptom distress was assessed by the Symptom Distress Scale at baseline and at 3 and 6 months. A multivariable analysis, using generalized estimating equations, showed that symptom distress was significantly less at 3 and 6 months (3 months: P < .001, 6 months: P = .002) than at baseline while controlling for demographic, biologic, psychological, treatment, and function covariates. Thoracic cancer, comorbidities, worse mental health, and decreased function were, on average, associated with increased symptom distress (all P < .05). Participants 75 years or older reported increased symptom distress over time compared with those aged 65 to 69 years (P < .05). Age, type of cancer, comorbidities, mental health, and function may influence older adults' symptom distress following cancer surgery. Older adults generally experience decreasing symptom distress after thoracic, abdominal, or pelvic cancer surgery. Symptom management over time for those with thoracic cancer, comorbidities, those with worse mental health, those with decreased function, and those 75 years or older may prevent morbidity and improve outcomes of older adults following surgery.

This study addressed three questions: (1) Do adolescents undergoing plastic surgery have a realistic view of their body? (2) How urgent is the psychosocial need of adolescents to undergo plastic surgery? (3) Which relations exist between bodily attitudes and psychosocial functioning and personality? From 1995 to 1997, 184 plastic surgical patients aged 12 to 22, and a comparison group of 684 adolescents and young adults from the general population aged 12 to 22 years, and their parents, were interviewed and completed questionnaires and standardised rating scales. Adolescents accepted for plastic surgery had realistic appearance attitudes and were psychologically healthy overall. Patients were equally satisfied with their overall appearance as the comparison group, but more dissatisfied with the specific body parts concerned for operation, especially when undergoing corrective operations. Patients had measurable appearance-related psychosocial problems. Patient boys reported less self-confidence on social areas than all other groups. There were very few patient-comparison group differences in correlations between bodily and psychosocial variables, indicating that bodily attitudes and satisfaction are not differentially related to psychosocial functioning and self-perception in patients than in peers. We concluded that adolescents accepted for plastic surgery have considerable appearance-related psychosocial problems, patients in the corrective group reporting more so than in the reconstructive group. Plastic surgeons may assume that these adolescents in general have a realistic attitude towards their appearance. are psychologically healthy, and are mainly dissatisfied about the body parts concerned for operation. corrective patients more so than reconstructive patients. Introverted patients may need more attention from plastic surgeons during the psychosocial assessment.

Elderly patients are often judged to be fit for emergency surgery based on age alone. This study identified risk factors predictive of in-hospital mortality amongst octogenarians undergoing emergency general surgery. A retrospective review of octogenarians undergoing emergency general surgery over 3 years was performed. Parametric survival analysis using Cox multivariate regression model was used to identify risk factors predictive of in-hospital mortality. Hazard ratios (HR) and corresponding 95% confidence interval were calculated. Seventy-three patients with a median age of 84 years were identified. Twenty-eight (38%) patients died post-operatively. Multivariate analysis identified ASA grade (ASA 5 HR 23.4 95% CI 2.38-230, p = 0.007) and chronic obstructive pulmonary disease (COPD) (HR 3.35 95% CI 1.15-9.69, p = 0.026) to be the only significant predictors of in-hospital mortality. Identification of high risk surgical patients should be based on physiological fitness for surgery rather than chronological age. Crown Copyright © 2014. Published by Elsevier Ltd.

To validate the Parsonnet scoring model to predict mortality following adult cardiac surgery in Indian scenario. A total of 889 consecutive patients undergoing adult cardiac surgery between January 2010 and April 2011 were included in the study. The Parsonnet score was determined for each patient and its predictive ability for in-hospital mortality was evaluated. The validation of Parsonnet score was performed for the total data and separately for the sub-groups coronary artery bypass grafting (CABG), valve surgery and combined procedures (CABG with valve surgery). The model calibration was performed using Hosmer-Lemeshow goodness of fit test and receiver operating characteristics (ROC) analysis for discrimination. Independent predictors of mortality were assessed from the variables used in the Parsonnet score by multivariate regression analysis. The overall mortality was 6.3% (56 patients), 7.1% (34 patients) for CABG, 4.3% (16 patients) for valve surgery and 16.2% (6 patients) for combined procedures. The Hosmer-Lemeshow statistic was <0.05 for the total data and also within the sub-groups suggesting that the predicted outcome using Parsonnet score did not match the observed outcome. The area under the ROC curve for the total data was 0.699 (95% confidence interval 0.62-0.77) and when tested separately, it was 0.73 (0.64-0.81) for CABG, 0.79 (0.63-0.92) for valve surgery (good discriminatory ability) and only 0.55 (0.26-0.83) for combined procedures. The independent predictors of mortality determined for the total data were low ejection fraction (odds ratio [OR] - 1.7), preoperative intra-aortic balloon pump (OR - 10.7), combined procedures (OR - 5.1), dialysis dependency (OR - 23.4), and re-operation (OR - 9.4). The Parsonnet score yielded a good predictive value for valve surgeries, moderate predictive value for the total data and for CABG and poor predictive value for combined procedures.

Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients. Five cases (0,025%) of intestinal malrotation were found. All of them were males, aging 45, 49, 37,52 and 39 years; BMI 35, 42, 49, 47 and 52 kg/m2, all of them with a past medical history of morbid obesity. The patient with BMI 35 kg/m2 suffered from type 2 diabetes also. All procedures were completed by laparoscopic approach, with no conversions. In one patient was not possible to move the jejunum to the upper abdomen in order to establish the gastrojejunostomy and a sleeve gastrectomy was performed. In another patient was not possible to fully recognize the anatomy due to bowel adhesions and a single anastomosis gastric bypass was preferred. No leaks or bleeding were identified. There were no perioperative complications. All patients were discharged 72 h after the procedure and no immediate 30-day complications were reported. Patients with malrotation can successfully undergo laparoscopic bariatric surgery. May be necessary changes in the surgical original strategy regarding the malrotation. Surgeons must check full abdominal anatomical condition prior to start the division of the stomach.

In open heart surgery using cardiopulmonary bypass, perfusion of the lower extremities is markedly reduced which may induce critical ischaemia in patients with pre-existing peripheral artery disease. Whether these patients have an increased risk for amputation and should better undergo peripheral revascularization prior to surgery remains unclear. From 1 January 2009 to 31 December 2010, 785 consecutive patients undergoing open heart surgery were retrospectively included. In 443 of these patients, preoperative ankle brachial index (ABI) measurements were available. The cohort was divided into four groups: (i) ABI < 0.5, (ii) ABI 0.5-0.69, (iii) ABI 0.7-0.89 or (iv) ABI ≥ 0.9. Follow-up data of 413 (93.2%) patients were analysed with regard to mortality and amputations. The groups differed significantly in terms of age, cardiac risk factors, performed cardiac surgery and renal function. Postoperative delayed wound healing was significantly associated with lower ABI (25.9, 15.2, 27.0 and 9.6% in Groups I-IV, respectively, P = 0.003), whereas 30-day mortality was not significantly higher in patients with lower ABI (0, 4.3, 8.1 and 3.9%, respectively, P = 0.4). Kaplan-Meier models showed a significantly lower long-term survival over 4 years in patients with reduced ABI (P = 0.001, long-rank test) while amputations occurred rarely with only one minor amputation in Group II (P = 0.023). Patients with reduced ABIs undergoing heart surgery showed more wound-healing disturbances, and higher long-term mortality compared with those with normal ABIs. However, no perioperative ischaemia requiring amputation occurred. Thus, reduced ABIs were not associated with increased peripheral risks in open heart surgery but ABI may be helpful in selecting the site for saphenectomy to potentially avoid delayed healing of related wounds in legs with severely impaired arterial perfusion. © The Author 2015.

To characterize cardiac arrest in children undergoing cardiac surgery using single-center data from the Society of Thoracic Surgeons and Pediatric Advanced Life Support Utstein-Style Guidelines. Patients aged 18 years or less having a cardiac arrest for 1 minute or more during the same hospital stay as heart operation qualified for inclusion (2002-2014). Patients having a cardiac arrest both before or after heart operation were included. Heart operations were classified on the basis of the first cardiovascular operation of each hospital admission (the index operation). The primary outcome was survival to hospital discharge. A total of 3437 children undergoing at least 1 heart operation were included. Overall rate of cardiac arrest among these patients was 4.5% (n = 154) with survival to hospital discharge of 84 patients (66.6%). Presurgery cardiac arrest was noted among 28 patients, with survival of 21 patients (75%). Among the 126 patients with postsurgery cardiac arrest, survival was noted among 84 patients (66.6%). Regardless of surgical case complexity, the median days between heart operation and cardiac arrest, duration of cardiac arrest, and survival after cardiac arrest were similar. The independent risk factors associated with improved chances of survival included shorter duration of cardiac arrest (odds ratio, 1.12; 95% confidence interval, 1.05-1.20; P = .01) and use of defibrillator (odds ratio, 4.51; 95% confidence interval, 1.08-18.87; P = .03). This single-center study demonstrates that characterizing cardiac arrest in children undergoing cardiac surgery using definitions from 2 societies helps to increase data granularity and understand the relationship between cardiac arrest and heart operation in a better way.

It is not known whether modern volatile anesthetics are associated with less mortality and postoperative pulmonary or other complications in patients undergoing general anesthesia for surgery. A systematic literature review was conducted for randomized controlled trials fulfilling following criteria: (1) population: adult patients undergoing general anesthesia for surgery; (2) intervention: patients receiving sevoflurane, desflurane, or isoflurane; (3) comparison: volatile anesthetics versus total IV anesthesia or volatile anesthetics; (4) reporting on: (a) mortality (primary outcome) and (b) postoperative pulmonary or other complications; (5) study design: randomized controlled trials. The authors pooled treatment effects following Peto odds ratio (OR) meta-analysis and network meta-analysis methods. Sixty-eight randomized controlled trials with 7,104 patients were retained for analysis. In cardiac surgery, volatile anesthetics were associated with reduced mortality (OR = 0.55; 95% CI, 0.35 to 0.85; P = 0.007), less pulmonary (OR = 0.71; 95% CI, 0.52 to 0.98; P = 0.038), and other complications (OR = 0.74; 95% CI, 0.58 to 0.95; P = 0.020). In noncardiac surgery, volatile anesthetics were not associated with reduced mortality (OR = 1.31; 95% CI, 0.83 to 2.05, P = 0.242) or lower incidences of pulmonary (OR = 0.67; 95% CI, 0.42 to 1.05; P = 0.081) and other complications (OR = 0.70; 95% CI, 0.46 to 1.05; P = 0.092). In cardiac, but not in noncardiac, surgery, when compared to total IV anesthesia, general anesthesia with volatile anesthetics was associated with major benefits in outcome, including reduced mortality, as well as lower incidence of pulmonary and other complications. Further studies are warranted to address the impact of volatile anesthetics on outcome in noncardiac surgery.

This is a retrospective analysis of administrative database. To elucidate the effect of glycemic control on surgical outcomes of middle-aged and elderly idiopathic scoliosis patients undergoing spinal fusion surgery. Diabetes mellitus (DM) is a condition thought to adversely affect outcomes of spine surgery. However, no study has stratified glycemic control levels and their impact on outcome for idiopathic scoliosis patients receiving a spinal fusion surgery. Previous studies may have reported higher than true rates of complications for controlled diabetic patients, who are the majority of diabetic patients. The Nationwide Inpatient Sample was queried from years 2002 to 2011. We extracted idiopathic scoliosis patients older than 45 years of age that received spinal fusion and analyzed complications and outcomes variables among 3 cohorts: nondiabetic patients, controlled diabetics, and uncontrolled diabetics. Multivariate analyses were used to assess whether glycemic control was a risk factor for adverse postoperative outcomes. Controlled diabetics had significantly increased rates of acute renal failure (ARF), while uncontrolled diabetics had significantly increased rates of acute postoperative hemorrhage. In multivariate analyses controlling for patient factors and comorbidities, controlled DM was found to be an independent predictor of ARF [odds ratio (OR), 1.863; 95% confidence interval (CI), 1.346-2.579; P=0.0002), and uncontrolled DM was found to be a significant risk factor for acute postoperative hemorrhage (OR, 2.182; 95% CI, 1.192-3.997; P=0.0115), ARF (OR, 4.839; 95% CI, 1.748-13.392; P=0.0024), deep vein thrombosis (OR, 5.825; 95% CI, 1.329-25.522, P=0.0194) and in-patient mortality (OR, 8.889; 95% CI, 1.001-78.945; P=0.0499). Controlled DM was found to be a risk factor for ARF in adult idiopathic scoliosis patients undergoing spinal fusion surgery, while uncontrolled DM was shown to be a risk factor for postoperative hemorrhage, ARF, deep vein

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

Prospective cross-sectional survey. To determine the perspectives of parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis (AIS) regarding simultaneous surgery and trainee participation. Simultaneous ("at the same time") surgery is under scrutiny by the public, government, payers and the medical community. The objective of this study is to determine the perspectives of parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis. Our goal is to inform the national conversation on this subject with real patient and family voices. A survey was prospectively administered to 31 consecutive parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis at a large academic medical center. "Overlapping" was defined as simultaneity during "noncritical" parts of an operation. "Concurrent" was defined as simultaneity that includes "critical" part(s) of an operation. Participants were asked to provide levels of agreement with overlapping and concurrent surgery and anesthesia, as well as with trainee involvement. On average, respondents "strongly agree" with the need to be informed about overlapping or concurrent surgery. They "disagree" with both overlapping and concurrent scheduling, and "disagree" with trainees operating without direct supervision, even for "non-critical" parts. Informing parents about the presence of a back-up surgeon or research demonstrating safety of simultaneous surgery did not make them agreeable to simultaneous scheduling. Parents have a strong desire to be informed of simultaneous spinal surgery as part of consent on behalf of their children. Their disagreement with simultaneous surgery, as well as with trainees operating without direct supervision, suggests discordance with current guidelines and practice and should inform the national conversation moving forward.

Perioperative goal-directed hemodynamic therapy (GDHT) has been advocated in high-risk patients undergoing noncardiac surgery to reduce postoperative morbidity and mortality. We hypothesized that using cardiac index (CI)-guided GDHT in the postoperative period for patients undergoing high-risk surgery for cancer treatment would reduce 30-day mortality and postoperative complications. A randomized, parallel-group, superiority trial was performed in a tertiary oncology hospital. All adult patients undergoing high-risk cancer surgery who required intensive care unit admission were randomly allocated to a CI-guided GDHT group or to a usual care group. In the GDHT group, postoperative therapy aimed at CI ≥ 2.5 L/min/m 2 using fluids, inotropes and red blood cells during the first 8 postoperative hours. The primary outcome was a composite endpoint of 30-day all-cause mortality and severe postoperative complications during the hospital stay. A meta-analysis was also conducted including all randomized trials of postoperative GDHT published from 1966 to May 2017. A total of 128 patients (64 in each group) were randomized. The primary outcome occurred in 34 patients of the GDHT group and in 28 patients of the usual care group (53.1% vs 43.8%, absolute difference 9.4 (95% CI, - 7.8 to 25.8); p = 0.3). During the 8-h intervention period more patients in the GDHT group received dobutamine when compared to the usual care group (55% vs 16%, p < 0.001). A meta-analysis of nine randomized trials showed no differences in postoperative mortality (risk ratio 0.85, 95% CI 0.59-1.23; p = 0.4; p for heterogeneity = 0.7; I 2  = 0%) and in the overall complications rate (risk ratio 0.88, 95% CI 0.71-1.08; p = 0.2; p for heterogeneity = 0.07; I 2  = 48%), but a reduced hospital length of stay in the GDHT group (mean difference (MD) - 1.6; 95% CI - 2.75 to - 0.46; p = 0.006; p for heterogeneity = 0.002; I 2  = 74%).

The aim of this review is to formulate practical recommendations for the management of antithrombotic therapy in patients undergoing cardiac implantable electronic device (CIED) surgery by providing indications for a systematic approach to the problem integrating general technical considerations with patient-specific elements based on a careful evaluation of the balance between haemorrhagic and thromboembolic risk. Hundreds of thousands patients undergo implantation or replacement of CIEDs annually in Europe, and up to 50% of these subjects receive antiplatelet agents or oral anticoagulants. The rate of CIED-related complications, mainly infective, has also significantly increased so that transvenous lead extraction procedures are, consequently, often required. Cardiac implantable electronic device surgery is peculiar and portends specific intrinsic risks of developing potentially fatal haemorrhagic complications; on the other hand, the periprocedural suspension of antithrombotic therapy in patients with high thromboembolic risk cardiac conditions may have catastrophic consequences. Accordingly, the management of the candidate to CIED surgery receiving concomitant antithrombotic therapy is a topic of great clinical relevance yet controversial and only partially, if at all, adequately addressed in evidence-based current guidelines. In spite of the fact that in many procedures it seems reasonably safe to proceed with aspirin only or without interruption of anticoagulants, restricting to selected cases the use of bridging therapy with parenteral heparins, there are lots of variables that may make the therapeutic choices challenging. The decision-making process applied in this document relies on the development of a stratification of the procedural haemorrhagic risk and of the risk deriving from the suspension of antiplatelet or anticoagulant therapy combined to generate different clinical scenarios with specific indications for optimal management of periprocedural

To construct a clinical decision support system (CDSS) for undergoing surgery based on domain ontology and rules reasoning in the setting of hospitalized diabetic patients. The ontology was created with a modified ontology development method, including specification and conceptualization, formalization, implementation, and evaluation and maintenance. The Protégé-Web Ontology Language editor was used to implement the ontology. Embedded clinical knowledge was elicited to complement the domain ontology with formal concept analysis. The decision rules were translated into JENA format, which JENA can use to infer recommendations based on patient clinical situations. The ontology includes 31 classes and 13 properties, plus 38 JENA rules that were built to generate recommendations. The evaluation studies confirmed the correctness of the ontology, acceptance of recommendations, satisfaction with the system, and usefulness of the ontology for glycemic management of diabetic patients undergoing surgery, especially for domain experts. The contribution of this research is to set up an evidence-based hybrid ontology and an evaluation method for CDSS. The system can help clinicians to achieve inpatient glycemic control in diabetic patients undergoing surgery while avoiding hypoglycemia.

The aim of this study was to develop a preoperative risk prediction model and an scorecard for prolonged intensive care unit length of stay (PrlICULOS) in adult patients undergoing heart valve surgery. This is a retrospective observational study of collected data on 3925 consecutive patients older than 18 years, who had undergone heart valve surgery between January 2000 and December 2010. Data were randomly split into a development dataset (n=2401) and a validation dataset (n=1524). A multivariate logistic regression analysis was undertaken using the development dataset to identify independent risk factors for PrlICULOS. Performance of the model was then assessed by observed and expected rates of PrlICULOS on the development and validation dataset. Model calibration and discriminatory ability were analysed by the Hosmer-Lemeshow goodness-of-fit statistic and the area under the receiver operating characteristic (ROC) curve, respectively. There were 491 patients that required PrlICULOS (12.5%). Preoperative independent predictors of PrlICULOS are shown with odds ratio as follows: (1) age, 1.4; (2) chronic obstructive pulmonary disease (COPD), 1.8; (3) atrial fibrillation, 1.4; (4) left bundle branch block, 2.7; (5) ejection fraction, 1.4; (6) left ventricle weight, 1.5; (7) New York Heart Association class III-IV, 1.8; (8) critical preoperative state, 2.0; (9) perivalvular leakage, 6.4; (10) tricuspid valve replacement, 3.8; (11) concurrent CABG, 2.8; and (12) concurrent other cardiac surgery, 1.8. The Hosmer-Lemeshow goodness-of-fit statistic was not statistically significant in both development and validation dataset (P=0.365 vs P=0.310). The ROC curve for the prediction of PrlICULOS in development and validation dataset was 0.717 and 0.700, respectively. We developed and validated a local risk prediction model for PrlICULOS after adult heart valve surgery. This model can be used to calculate patient-specific risk with an equivalent predicted risk at our centre in

Previous studies performed in non-obese patients undergoing elective surgery have revealed that psychological factors may affect postoperative analgesic requirements. The aim of this observational prospective study was to investigate the extent to which psychopathological dimensions, including anxiety, depression and alexithymia, may influence postoperative pain intensity and analgesics consumption using patient-controlled analgesia (PCA) in patients undergoing bariatric surgery. 120 patients, aged 18-60years, with an ASA physical status I-II, undergoing gastric bypass were enrolled. Anxiety and depression Hamilton scales, and Toronto Alexithymia scale, were administered to patients on the day before surgery. General anesthesia was standardized. After awakening, a PCA pump with intravenous tramadol was immediately made available for a 36-hour postoperative analgesia. Visual analog scale at rest (VASr) and after coughing (VASi), and effective PCA requests number were postoperatively recorded. Pearson's correlations, Anova analyses and multiple linear regression were used for statistical purpose. Positive correlations were found between anxiety, depression, alexithymia and all pain indicators (p<0.01). Analyses of variance showed that anxious (p<0.001), depressed (p<0.001) and alexithymic (p<0.05) patients had high pain indicators. VASr and VASi were predicted by anxiety and depression (p<0.05), but not by alexithymia; effective PCA requests number was predicted by anxiety, depression and alexithymia (p<0.001). Obese patients with high depression, anxiety and alexithymia levels rated their pain as more intense and required a larger amount of tramadol. Pain perception intensity was predicted by anxiety and depression but not by alexithymia, whereas analgesics consumption was predicted by all the investigated psychopathological dimensions.

It has been previously demonstrated that T lymphocytes may be involved in the development of hypertension and microvascular remodeling, and that circulating T effector lymphocytes may be increased in hypertension. In particular, Th1 and Th 17 lymphocytes may contribute to the progression of hypertension and microvascular damage while T-regulatory (Treg) lymphocytes seem to be protective in this regard. However, no data is available about patients with severe obesity, in which pronounced microvascular alterations were observed. We have investigated 32 severely obese patients undergoing bariatric surgery, as well as 24 normotensive lean subjects and 12 hypertensive lean subjects undergoing an elective surgical intervention. A peripheral blood sample was obtained before surgery for assessment of CD4+ T lymphocyte subpopulations. Lymphocyte phenotype was evaluated by flow cytometry in order to assess T-effector and Treg lymphocytes. A marked reduction of several Treg subpopulations was observed in obese patients compared with controls, together with an increased in CD4+ effector memory T-effector cells. In severely obese patients, Treg lymphocytes are clearly reduced and CD4+ effector memory cells are increased. It may be hypothesized that they might contribute to the development of marked microvascular alterations previously observed in these patients.

2014-01-01

Introduction The aim of this study was to identify the determinants of distance walked in six-minute walk test (6MWD) in patients undergoing cardiac surgery at hospital discharge. Methods The assessment was performed preoperatively and at discharge. Data from patient records were collected and measurement of the Functional Independence Measure (FIM) and the Nottingham Health Profile (NHP) were performed. The six-minute walk test (6MWT) was performed at discharge. Patients undergoing elective cardiac surgery, coronary artery bypass grafting or valve replacement were eligible. Patients older than 75 years who presented arrhythmia during the protocol, with psychiatric disorders, muscular or neurological disorders were excluded from the study. Results Sixty patients (44.26% male, mean age 51.53 ± 13 years) were assessed. In multivariate analysis the following variables were selected: type of surgery (P = 0.001), duration of cardiopulmonary bypass (CPB) (P = 0.001), Functional Independence Measure - FIM (0.004) and body mass index - BMI (0.007) with r = 0.91 and r2 = 0.83 with P < 0.001. The equation derived from multivariate analysis: 6MWD = Surgery (89.42) + CPB (1.60) + MIF (2.79 ) - BMI (7.53) - 127.90. Conclusion In this study, the determinants of 6MWD in patients undergoing cardiac surgery were: the type of surgery, CPB time, functional capacity and body mass index. PMID:24885130

The presence of clowns in health care settings is a program used in many countries to reduce distress in children who are undergoing surgery. The aim of the present study is to determine the effect of the presence of clowns on children's distress and maladaptive behaviours while in hospital for minor surgery. The sample consisted of 61 pediatric patients (aged 3-12 years) undergoing general anesthesia for minor surgery. Participants were assigned to two groups: experimental and control group. The child's distress was assessed using FAS (Facial Affective Scale). Postoperative maladaptive behaviors were evaluated one week after surgery, using the PHBQ (Post-Hospital Behavior Questionnaire). Our results suggest that clowns are not able to reduce the child's level of distress. However, postoperative maladaptive behaviours in the experimental group decreased, but the decrease was not statistically significant. Further research is needed to determine the effects of clowns in hospitals, taking into account age, sex, parents' presence, and diverse hospital settings.

The purpose of this study was to determine the efficacy of a cognitive-behavioral based physical therapy (CBPT) program for improving outcomes in patients following lumbar spine surgery. A randomized controlled trial was conducted in 86 adults undergoing a laminectomy with or without arthrodesis for a lumbar degenerative condition. Patients were screened preoperatively for high fear of movement using the Tampa Scale for Kinesiophobia. Randomization to either CBPT or an Education program occurred at 6 weeks after surgery. Assessments were completed pre-treatment, post-treatment and at 3 month follow-up. The primary outcomes were pain and disability measured by the Brief Pain Inventory and Oswestry Disability Index. Secondary outcomes included general health (SF-12) and performance-based tests (5-Chair Stand, Timed Up and Go, 10 Meter Walk). Multivariable linear regression analyses found that CBPT participants had significantly greater decreases in pain and disability and increases in general health and physical performance compared to the Education group at 3 month follow-up. Results suggest a targeted CBPT program may result in significant and clinically meaningful improvement in postoperative outcomes. CBPT has the potential to be an evidence-based program that clinicians can recommend for patients at-risk for poor recovery following spine surgery. PMID:26476267

To describe the successful perioperative hemostatic management of a Jehovah's Witness patient with hemophilia B and anaphylactic inhibitors to factor IX, undergoing scoliosis surgery. A 14 (1/2)-yr-old boy with severe hemophilia B who had a history of anaphylactic inhibitors to factor IX was scheduled to undergo corrective scoliosis surgery. He was initially started on epoetin alfa and iron supplementation to maximize preoperative red cell mass. Additionally, he was placed on a desensitization protocol of recombinant coagulation factor IX (rFIX) and was then treated with activated recombinant coagulation factor VII (rFVIIa) during the postoperative period. Tranexamic acid was given concomitantly. The intraoperative blood loss was approximately 350 mL. The nadir hemoglobin concentration was 111 g.L(-1) on postoperative days one and two. On postoperative day 11, the patient was stable and discharged home with a hemoglobin of 138 g.L(-1). He did not require blood transfusion and no adverse events were observed. The use of rFIX, rFVIIa, erythropoetin, iron, and tranexamic acid before, during and after scoliosis surgery may be a viable and safe option for hemophilia patients with inhibitors, who refuse blood products.

Levosimendan is an inotropic agent that has been shown in small studies to prevent or treat the low cardiac output syndrome after cardiac surgery. In a multicenter, randomized, placebo-controlled, phase 3 trial, we evaluated the efficacy and safety of levosimendan in patients with a left ventricular ejection fraction of 35% or less who were undergoing cardiac surgery with the use of cardiopulmonary bypass. Patients were randomly assigned to receive either intravenous levosimendan (at a dose of 0.2 μg per kilogram of body weight per minute for 1 hour, followed by a dose of 0.1 μg per kilogram per minute for 23 hours) or placebo, with the infusion started before surgery. The two primary end points were a four-component composite of death through day 30, renal-replacement therapy through day 30, perioperative myocardial infarction through day 5, or use of a mechanical cardiac assist device through day 5; and a two-component composite of death through day 30 or use of a mechanical cardiac assist device through day 5. A total of 882 patients underwent randomization, 849 of whom received levosimendan or placebo and were included in the modified intention-to-treat population. The four-component primary end point occurred in 105 of 428 patients (24.5%) assigned to receive levosimendan and in 103 of 421 (24.5%) assigned to receive placebo (adjusted odds ratio, 1.00; 99% confidence interval [CI], 0.66 to 1.54; P=0.98). The two-component primary end point occurred in 56 patients (13.1%) assigned to receive levosimendan and in 48 (11.4%) assigned to receive placebo (adjusted odds ratio, 1.18; 96% CI, 0.76 to 1.82; P=0.45). The rate of adverse events did not differ significantly between the two groups. Prophylactic levosimendan did not result in a rate of the short-term composite end point of death, renal-replacement therapy, perioperative myocardial infarction, or use of a mechanical cardiac assist device that was lower than the rate with placebo among patients with a

Postoperative ileus (POI) is a common complication after spine surgery, with particularly high rates after adult spinal deformity surgery (ASD). Few investigations have been conducted, however, on predictors of POI following ASD. The objective of this investigation was to determine risk factors for POI in patients undergoing ASD. We also sought to determine the association between POI and in-hospital mortality, length of stay, and total charges. Data were obtained from the National/Nationwide Inpatient Sample, years 2010 - 2014. ASD patients aged ≥26 years-old were selected using ICD-9-CM codes. Multiple logistic and linear regression were utilized. In total, 59,410 patients were included in the analysis. 7.4% of patients experienced POI. On adjusted analysis, the following variables were associated with increased risk of POI: male sex (OR 1.43, CI 1.10 - 1.85), anterior surgical approach (OR 1.78, CI 1.22 - 2.60), 9+ levels fused (OR 1.84, CI 1.24 - 2.73), electrolyte disorders (OR 2.70, CI 2.15 - 3.39), and pathologic weight loss (OR 1.94, CI 1.08 - 3.46). POI was associated with significantly longer length of stay (+39%, CI 29% - 51%) and higher total charges (+23%, CI 14% - 31%). Risk factors for POI were identified. Patients suffering from ileus exhibited 2.9 days longer length of stay and ∼$80,000 higher total charges. These results may be applied clinically to identify patients at risk of POI and to consider addressing modifiable risk factors preoperatively. Future studies should be conducted with additional data to develop models capable of accurately predicting and preventing POI. Copyright © 2018 Elsevier Inc. All rights reserved.

Use of perioperative dialogues with children undergoing day surgery.

Wennström, Berith; Hallberg, Lillemor R-M; Bergh, Ingrid

2008-04-01

This paper is a report of a study to explore what it means for children to attend hospital for day surgery. Hospitalization is a major stressor for children. Fear of separation, unfamiliar routines, anaesthetic/operation expectations/experiences and pain and needles are sources of children's negative reactions. A grounded theory study was carried out during 2005-2006 with 15 boys and five girls (aged 6-9 years) scheduled for elective day surgery. Data were collected using tape-recorded interviews that included a perioperative dialogue, participant observations and pre- and postoperative drawings. A conceptual model was generated on the basis of the core category 'enduring inflicted hospital distress', showing that the main problem for children having day surgery is that they are forced into an unpredictable and distressful situation. Pre-operatively, the children do not know what to expect, as described in the category 'facing an unknown reality'. Additional categories show that they perceive a 'breaking away from daily routines' and that they are 'trying to gain control' over the situation. During the perioperative period, the categories 'losing control' and 'co-operating despite fear and pain' are present and intertwined. Post-operatively, the categories 'breathing a sigh of relief' and 'regaining normality in life' emerged. The perioperative dialogue used in our study, if translated into clinical practice, might therefore minimize distress and prepare children for the 'unknown' stressor that hospital care often presents. Further research is needed to compare anxiety and stress levels in children undergoing day surgery involving the perioperative dialogue and those having 'traditional' anaesthetic care.

Retrospective cohort. To determine if the use of cell saver reduces overall blood costs in adult spinal deformity (ASD) surgery. Recent studies have questioned the clinical value of cell saver during spine procedures. ASD patients enrolled in a prospective, multicenter surgical database who had complete preoperative and surgical data were identified. Patients were stratified into (1) cell saver available during surgery, but no intraoperative autologous infusion (No Infusion group), or (2) cell saver available and received autologous infusion (Infusion group). There were 427 patients in the Infusion group and 153 in the No infusion group. Patients in both groups had similar demographics. Mean autologous infusion volume was 698 mL. The Infusion group had a higher percentage of EBL relative to the estimated blood volume (42.2%) than the No Infusion group (19.6%, p < .000). Allogeneic transfusion was more common in the Infusion group (255/427, 60%) than the No Infusion group (67/153, 44%, p = .001). The number of allogeneic blood units transfused was also higher in the Infusion group (2.4) than the No Infusion group (1.7, p = .009). Total blood costs ranged from $396 to $2,146 in the No Infusion group and from $1,262 to $5,088 in the Infusion group. If the cost of cell saver blood was transformed into costs of allogeneic blood, total blood costs for the Infusion group would range from $840 to $5,418. Thus, cell saver use yielded a mean cost savings ranging from $330 to $422 (allogeneic blood averted). Linear regression showed that after an EBL of 614 mL, cell saver becomes cost-efficient. Compared to transfusing allogeneic blood, cell saver autologous infusion did not reduce the proportion or the volume of allogeneic transfusion for patients undergoing surgery for adult spinal deformity. The use of cell saver becomes cost-efficient above an EBL of 614 mL, producing a cost savings of $330 to $422. Level III. Copyright © 2017 Scoliosis Research Society. Published by

Music has been proposed as a safe, inexpensive, nonpharmacological antistress intervention. The purpose of this study was to determine whether patients undergoing cataract surgery while listening to meditation music experience lower levels of blood pressure and heart rate. Two hundred individuals undergoing cataract surgery participated in the study. Hundred individuals listened to meditation music, through headphones, before and during the operation (intervention group) and 100 individuals received standard care (control group). Patients stress coping skills were measured by the Sense of Coherence Scale (SOC Scale). Systolic and diastolic blood pressure and heart rate were defined as outcome measures. According to the SOC Scale, both groups had similar stress coping skills (mean score: 127.6 for the intervention group and 127.3 for the control group). Before entering the operating room (OR) as well as during surgery the rise in systolic and diastolic pressures was significantly lower in the intervention group (P < 0.001). Among patients receiving antihypertensive therapy, those in the intervention group presented a lower increase only in systolic pressure (P < 0.001) at both time recordings. For those patients in the intervention group who did not receive antihypertensive treatment, lower systolic blood pressure at both time recordings was recorded (P < 0.001) while lower diastolic pressure was observed only during entry to the OR (P = 0.021). Heart rate was not altered between the two groups in any of the recordings. Meditation music influenced patients' preoperative stress with regard to systolic blood pressure. This kind of music can be used as an alternative or complementary method for blood pressure stabilizing in patients undergoing cataract surgery.

Minimally invasive valve surgery has been associated with increased cerebrovascular complications. Our objective was to evaluate the incidence of cerebrovascular accidents in patients undergoing minimally invasive valve surgery. We retrospectively reviewed all the minimally invasive valve surgery performed at our institution from January 2009 to June 2012. The operative times, lengths of stay, postoperative complications, and mortality were analyzed. A total of 1501 consecutive patients were identified. The mean age was 73 ± 13 years, and 808 patients (54%) were male. Of the 1501 patients, 206 (13.7%) had a history of a cerebrovascular accident, and 225 (15%) had undergone previous heart surgery. The procedures performed were 617 isolated aortic valve replacements (41.1%), 658 isolated mitral valve operations (43.8%), 6 tricuspid valve repairs (0.4%), 216 double valve surgery (14.4%), and 4 triple valve surgery (0.3%). Femoral cannulation was used in 1359 patients (90.5%) and central cannulation in 142 (9.5%). In 1392 patients (92.7%), the aorta was clamped, and in 109 (7.3%), the surgery was performed with the heart fibrillating. The median aortic crossclamp and cardiopulmonary bypass times were 86 minutes (interquartile range [IQR], 70-107) minutes and 116 minutes (IQR, 96-143), respectively. The median intensive care unit length of stay was 47 hours (IQR, 29-74), and the median postoperative hospital length of stay was 7 days (IQR, 5-10). A total of 23 cerebrovascular accidents (1.53%) and 38 deaths (2.53%) had occurred at 30 days postoperatively. Minimally invasive valve surgery was associated with an acceptable stroke rate, regardless of the cannulation technique. Copyright © 2014 The American Association for Thoracic Surgery.

2017-10-01

Transsphenoidal surgery is the gold standard for pituitary adenoma resection. However, despite advances in microsurgical and endoscopic techniques, some pituitary adenomas can be challenging to cure. We sought to determine whether, in patients undergoing transsphenoidal surgery for pituitary adenoma, intraoperative ultrasound is a safe and effective technologic adjunct. The PubMed database was searched between January 1996 and January 2016 to identify relevant publications that 1) featured patients undergoing transsphenoidal surgery for pituitary adenoma, 2) used intraoperative ultrasound, and 3) reported on safety or effectiveness. Reference lists were also checked, and expert opinions were sought to identify further publications. Ultimately, 10 studies were included, comprising 1 cohort study, 7 case series, and 2 case reports. One study reported their prototype probe malfunctioned, leading to false-positive results in 2 cases, and another study' prototype probe was too large to safely enter the sphenoid sinus in 2 cases. Otherwise, no safety issues directly related to use of intraoperative ultrasound were reported. In the only comparative study, remission occurred in 89.7% (61/68) of patients with Cushing disease in whom intraoperative ultrasound was used, compared with 83.8% (57/68) in whom it was not. All studies reported that surgeons anecdotally found intraoperative ultrasound helpful. Although there is limited and low-quality evidence available, the use of intraoperative ultrasound appears to be a safe and effective technologic adjunct to transsphenoidal surgery for pituitary adenoma. Advances in ultrasound technology may allow for more widespread use of such devices. Copyright © 2017 Elsevier Inc. All rights reserved.

This study explores the association between perioperative hypoglycaemia and surgical outcomes in subjects with diabetes, undergoing colorectal surgery. A retrospective review of 149 subjects with Type 2 Diabetes Mellitus (DM) who underwent colorectal surgery between 2010 and 2015 was performed. Perioperative glucose levels, glycated haemoglobin (HbA1c) measurements within 3 months of surgery and surgical complications based on Clavien-Dindo classification were analysed. The mean age was 67 years (67 ± 11.2). Perioperative hypoglycaemia was found in 7.4% of subjects. The mean HbA1c of subjects with Clavien 2 and above surgical complications were higher than patients with Clavien 1 or no complications, Hba1c 7.6% (7.6 ± 2.5%) and 7.0% (7.0 ± 1.1%, p = 0.008), respectively. Similar findings in subjects with Clavien 3 and above complications, HbA1c of 8.2% (8.2 ± 3.9%) as compared to those with Clavien 2 and below complications, 7.2% (7.2 ± 1.5%, p = 0.001). Adjusted multivariate analysis showed that hypoglycaemia was significantly associated with Clavien 2 and above surgical complications, OR of 19.0 (CI 2.23-162, p = 0.007). Preoperative hypoglycaemia was associated with Clavien 2 and above surgical complications, OR 10.7 (CI 1.22-94.1, p = 0.032). Suboptimal glycaemic control (Hba1c >8.0%) was significantly associated with Clavien 2 and above complications, OR 2.48 (CI 1.04-5.91, p = 0.04), but not with Clavien 3 and above complications, OR 1.50 (CI 0.450-4.98, p = 0.511). Perioperative hypoglycaemia is associated with adverse surgical outcomes in diabetic patients undergoing colorectal surgery. Prevention of hypoglycaemia may improve surgical outcomes. HbA1c is an independent predictor for adverse surgical outcomes.

Is low serum albumin associated with postoperative complications in patients undergoing cardiac surgery?

A best evidence topic was written according to a structured protocol. The clinical question investigated was: is low serum albumin associated with postoperative complications in patients undergoing cardiac surgery? There were 62 papers retrieved using the reported search strategy. Of these, 12 publications embodied the best evidence to answer this clinical question. The authors, journal, date and country of the publication, patient group investigated, study design, relevant outcomes and results of these papers were tabulated. This paper includes a total of 12 589 patients, and of the papers reviewed, 4 were level 3 and 8 level 4. Each of the publications reviewed and compared either all or some of the following postoperative complications: mortality, postoperative bleeding requiring reoperation, prolonged hospital stay and ventilatory support, infection, liver dysfunction, delirium and acute kidney injury (AKI). Of the studies that examined postoperative mortality, all except for three established a significant multivariate association with low preoperative albumin level. Some scepticism is required in accepting other results that were only present in univariate analysis. While three studies examined multiple levels of serum albumin, most dichotomized the serum albumin levels into normal and abnormal groups. This led to differing classifications of hypoalbuminaemia, ranging from less than 2.5 to 4.0 g/dl. The available evidence, however, suggests that low preoperative serum albumin level in patients undergoing cardiac surgery is associated with the following: (i) increased risk of mortality after surgery and (ii) greater incidence of postoperative morbidity. While the evidence supports the use of preoperative albumin in assessing post-cardiac surgery complications, a specific level of albumin considered to be abnormal cannot be concluded from this review. © The Author 2015.

The objective of this study was determine the frequency of symptomatic perioperative venous thromboembolism (VTE) and risk factor(s) associated with VTE occurrence in women undergoing elective pelvic reconstructive surgery using only intermittent pneumatic compression (IPC) for VTE prophylaxis. A multi-center case-cohort retrospective review was conducted at six clinical sites over a 66-month period. All sites utilize IPC as standard VTE prophylaxis for urogynecological surgery. VTE cases occurring during the same hospitalization and up to 6 weeks postoperatively were identified by ICD9 code query. Four controls were temporally matched to each case. Information collected included demographics, medical history, route of surgery, operative time, and intraoperative characteristics. Univariate and multivariate backward stepwise logistic regression analyses were performed to identify potential risk factors for VTE. Symptomatic perioperative VTE was diagnosed in 27 subjects from a cohort of 10,627 women who underwent elective urogynecological surgery (0.25 %). Univariate analysis identified surgical route (laparotomy vs others), type of surgery ("major" vs "minor"), history of gynecological cancer, surgery time, and patient age as risk factors for VTE (P < 0.05). Multivariate analysis identified increased frequency of VTE with laparotomy, age ≥ 70, and surgery duration ≥ 5 h. In our study cohort, the frequency of symptomatic perioperative VTE was low. Laparotomy, age ≥ 70 years, and surgery duration ≥ 5 h were associated with VTE occurrence.

Music therapy, an innovative approach that has proven effectiveness in many medical conditions, seems beneficial also in managing surgical patients. The aim of this study is to evaluate its effects, under general anesthesia, on perioperative patient satisfaction, stress, pain, and awareness. This is a prospective, randomized, double-blind study conducted in the operating theatre of visceral surgery at Sahloul Teaching Hospital over a period of 4 months. Patients aged more than 18 undergoing a scheduled surgery under general anesthesia were included. Patients undergoing urgent surgery or presenting hearing or cognitive disorders were excluded. Before induction, patients wore headphones linked to an MP3 player. They were randomly allocated into 2 groups: Group M (with music during surgery) and group C (without music). Hemodynamic parameters, quality of arousal, pain experienced, patient's satisfaction, and awareness incidence during anesthesia were recorded. One hundred and forty patients were included and allocated into 2 groups that were comparable in demographic characteristics, surgical intervention type and anesthesia duration. Comparison of these two groups regarding the hemodynamic profile found more stability in group M for systolic arterial blood pressure. A calm recovery was more often noted in group M (77.1% versus 44%, p < 10 -3 ). The average Visual Analog Scale (VAS) score was lower in the intervention group (33.8 ± 13.63 versus 45.1 ± 16.2; p < 10 -3 ). The satisfaction rate was significantly higher among the experimental group (81.4% versus 51.4%; p < 10 -3 ). The incidence of intraoperative awareness was higher in group C (8 cases versus 3 cases) but the difference was not statistically significant. Music therapy is a non-pharmacological, inexpensive, and non-invasive technique that can significantly enhance patient satisfaction and decrease patients' embarrassing experiences related to perioperative stress, pain, and awareness.

Abstract Objective: To construct a clinical decision support system (CDSS) for undergoing surgery based on domain ontology and rules reasoning in the setting of hospitalized diabetic patients. Materials and Methods: The ontology was created with a modified ontology development method, including specification and conceptualization, formalization, implementation, and evaluation and maintenance. The Protégé–Web Ontology Language editor was used to implement the ontology. Embedded clinical knowledge was elicited to complement the domain ontology with formal concept analysis. The decision rules were translated into JENA format, which JENA can use to infer recommendations based on patient clinical situations. Results: The ontology includes 31 classes and 13 properties, plus 38 JENA rules that were built to generate recommendations. The evaluation studies confirmed the correctness of the ontology, acceptance of recommendations, satisfaction with the system, and usefulness of the ontology for glycemic management of diabetic patients undergoing surgery, especially for domain experts. Conclusions: The contribution of this research is to set up an evidence-based hybrid ontology and an evaluation method for CDSS. The system can help clinicians to achieve inpatient glycemic control in diabetic patients undergoing surgery while avoiding hypoglycemia. PMID:24730353

Does intraoperative facial nerve monitoring during vestibular schwannoma surgery lead to better long-term facial nerve function? This recommendation applies to adult patients undergoing vestibular schwannoma surgery regardless of tumor characteristics. Level 3: It is recommended that intraoperative facial nerve monitoring be routinely utilized during vestibular schwannoma surgery to improve long-term facial nerve function. Can intraoperative facial nerve monitoring be used to accurately predict favorable long-term facial nerve function after vestibular schwannoma surgery? This recommendation applies to adult patients undergoing vestibular schwannoma surgery. Level 3: Intraoperative facial nerve can be used to accurately predict favorable long-term facial nerve function after vestibular schwannoma surgery. Specifically, the presence of favorable testing reliably portends a good long-term facial nerve outcome. However, the absence of favorable testing in the setting of an anatomically intact facial nerve does not reliably predict poor long-term function and therefore cannot be used to direct decision-making regarding the need for early reinnervation procedures. Does an anatomically intact facial nerve with poor electromyogram (EMG) electrical responses during intraoperative testing reliably predict poor long-term facial nerve function? This recommendation applies to adult patients undergoing vestibular schwannoma surgery. Level 3: Poor intraoperative EMG electrical response of the facial nerve should not be used as a reliable predictor of poor long-term facial nerve function. Should intraoperative eighth cranial nerve monitoring be used during vestibular schwannoma surgery? This recommendation applies to adult patients undergoing vestibular schwannoma surgery with measurable preoperative hearing levels and tumors smaller than 1.5 cm. Level 3: Intraoperative eighth cranial nerve monitoring should be used during vestibular schwannoma surgery when hearing preservation

Atelectasis occurs regularly after induction of general anesthesia, persists postoperatively, and may contribute to significant postoperative morbidity and additional health care costs. Laparoscopic surgery has been reported to be associated with an increased incidence of postoperative atelectasis. It has been shown that during general anesthesia, obese patients have a greater risk of atelectasis than nonobese patients. Preventing atelectasis is important for all patients but is especially important when caring for obese patients. We randomly allocated 66 adult obese patients with a body mass index between 30 and 50 kg/m(2) scheduled to undergo laparoscopic bariatric surgery into 3 groups. According to the recruitment maneuver used, the zero end-expiratory pressure (ZEEP) group (n = 22) received the vital capacity maneuver (VCM) maintained for 7-8 s applied immediately after intubation plus ZEEP; the positive end-expiratory pressure (PEEP) 5 group (n = 22) received the VCM maintained for 7-8 s applied immediately after intubation plus 5 cm H(2)O of PEEP; and the PEEP 10 group (n = 22) received the VCM maintained for 7-8 s applied immediately after intubation plus 10 cm H(2)O of PEEP. All other variables (e.g., anesthetic and surgical techniques) were the same for all patients. Heart rate, noninvasive mean arterial blood pressure, arterial oxygen saturation, and alveolar-arterial Pao(2) gradient (A-a Pao(2)) were measured intraoperatively and postoperatively in the postanesthesia care unit (PACU). Length of stay in the PACU and the use of a nonrebreathing O(2) mask (100% Fio(2)) or reintubation were also recorded. A computed tomographic scan of the chest was performed preoperatively and postoperatively after discharge from the PACU to evaluate lung atelectasis. Patients in the PEEP 10 group had better oxygenation both intraoperatively and postoperatively in the PACU, lower atelectasis score on chest computed tomographic scan, and less postoperative pulmonary

This study aimed to develop and assess the effectiveness of a protocol for antibiotic prophylaxis based on preoperative kidney function in patients undergoing open heart surgery. We established a protocol for antibiotic prophylaxis based on preoperative kidney function in patients undergoing open heart surgery. This novel protocol was assessed by comparing patients undergoing open heart surgery before (control group; n = 30) and after its implementation (protocol group; n = 31) at Kyoto University Hospital between July 2012 and January 2013. Surgical site infections (SSIs) were observed in 4 control group patients (13.3 %), whereas no SSIs were observed in the protocol group patients (P < 0.05). The total duration of antibiotic use decreased significantly from 80.7 ± 17.6 h (mean ± SD) in the control group to 55.5 ± 14.9 h in the protocol group (P < 0.05). Similarly, introduction of the protocol significantly decreased the total antibiotic dose used in the perioperative period (P < 0.05). Furthermore, antibiotic regimens were changed under suspicion of infection in 5 of 30 control group patients, whereas none of the protocol group patients required this additional change in the antibiotic regimen (P < 0.05). Our novel antibiotic prophylaxis protocol based on preoperative kidney function effectively prevents SSIs in patients undergoing open heart surgery.

Electrical impedance tomography (EIT) can determine ventilation and perfusion relationship. Most of the data obtained so far originates from experimental settings and in healthy subjects. The aim of this study was to demonstrate that EIT measures the perioperative changes in pulmonary blood flow after repair of a ventricular septum defect in children with haemodynamic relevant septal defects undergoing open heart surgery. In a 19 bed intensive care unit in a tertiary children's hospital ventilation and cardiac related impedance changes were measured using EIT before and after surgery in 18 spontaneously breathing patients. The EIT signals were either filtered for ventilation (ΔZV) or for cardiac (ΔZQ) related impedance changes. Impedance signals were then normalized (normΔZV, normΔZQ) for calculation of the global and regional impedance related ventilation perfusion relationship (normΔZV/normΔZQ). We observed a trend towards increased normΔZV in all lung regions, a significantly decreased normΔZQ in the global and anterior, but not the posterior lung region. The normΔZV/normΔZQ was significantly increased in the global and anterior lung region. Our study qualitatively validates our previously published modified EIT filtration technique in the clinical setting of young children with significant left-to-right shunt undergoing corrective open heart surgery, where perioperative assessment of the ventilation perfusion relation is of high clinical relevance.

Menopausal symptoms are associated with a negative impact on the quality of life, leading women to seek medical treatment. Obesity has been linked to higher levels of menopausal symptoms such as hot flushes. This assessment will explore whether the prevalence and bother of hot flushes and vaginal dryness change from pre- to post-bariatric surgery among obese midlife women. This study is a longitudinal analysis of data from 69 women (ages 35-72 years) undergoing bariatric surgery with reported reproductive histories and menopausal symptoms at preoperative and 6-month postoperative visits. Prevalence of and degree of bother of hot flushes and vaginal dryness at pre- and post-surgery were compared using McNemar's test and Wilcoxon signed-rank test. The reported degree of bother of symptoms associated with hot flushes decreased from pre- to post-surgery (p < 0.01). There was no significant change in the prevalence of hot flushes or vaginal dryness in the overall study sample. The degree of bother of symptoms associated with hot flushes among midlife women may decrease after bariatric surgery. These results highlight important secondary gains, including less bothersome menopausal symptoms, for women who choose bariatric surgery for weight loss.

The utility of routine preoperative electrocardiography (ECG) for assessing perioperative cardiovascular risk in patients undergoing noncardiac, nonvascular surgery (NCNVS) is unclear. There would be an association between preoperative ECG and perioperative cardiovascular outcomes in patients undergoing NCNVS. A total of 660 patients undergoing NCNVS were prospectively evaluated. Patients age >18 years who underwent an elective, nonday case, open surgical procedure were enrolled. Troponin I concentrations and 12-lead ECG were evaluated the day before surgery, immediately after surgery, and on the first 5 postoperative days. Preoperative ECG showing atrial fibrillation, left or right bundle branch block, left ventricular hypertrophy, frequent premature ventricular complexes, pacemaker rhythm, Q-wave, ST-segment changes, or sinus tachycardia or bradycardia were classified as abnormal. The patients were followed up during hospitalization and were evaluated for the presence of perioperative cardiovascular events (PCE). Eighty patients (12.1%) experienced PCE. Patients with abnormal ECG findings had a greater incidence of PCE than those with normal ECG results (16% vs 6.4%; P < 0.001). Mean QTc interval was significantly longer in the patients who had PCE (436.6 ± 31.4 vs 413.3 ± 16.7 ms; P < 0.001). Univariate analysis showed a significant association between preoperative atrial fibrillation, pacemaker rhythm, ST-segment changes, QTc prolongation, and in-hospital PCE. However, only QTc prolongation (odds ratio: 1.15, 95% confidence interval: 1.06-1.2, P < 0.001) was an independent predictor of PCE according to the multivariate analysis. Every 10-ms increase in QTc interval was related to a 13% increase for PCE. Prolongation of the QTc interval on the preoperative ECG was related with PCE in patients undergoing NCNVS. © 2011 Wiley Periodicals, Inc.

The cardiovascular response to decreased or increased preload in high-risk patients with ischemic heart disease enables us to understand the physiologic response to hemorrhage and its treatment. Although numerous studies have failed to show its effectiveness, the head-down position is still widely used to treat patients with hypotension and shock. The aim of our study was to evaluate the influence of body position on hemodynamics in high-risk patients undergoing coronary artery bypass graft surgery. In 16 patients with ischemic hearth disease and poor left ventricular function undergoing coronary artery bypass graft surgery, we measured cardiac output with thermodilution, arterial pressure, central venous pressure (CVP), pulmonary artery wedge pressure (PAWP) and heart rate in three different body positions: the horizontal position, 20 degrees head-up position, 20 degrees head-down position and back in the horizontal position. The measurements were made before and after cardiac surgery. Before skin incision the change from horizontal to 20 degrees head-up position led to a nonsignificant decrease in cardiac output and a significant decrease in mean arterial pressure, CVP and PAWP. The change from 20 degrees head-up to 20 degrees head-down position led to a significant increase in cardiac output, mean arterial pressure, CVP and PAWP. After skin closure the change from horizontal to 20 degrees head-up position led to a nonsignificant decrease in cardiac output and mean arterial pressure and a significant decrease CVP and PAWP. The change from 20 degrees head-up to 20 degrees head-down position led to a nonsignificant increase in cardiac output and a significant increase in mean arterial pressure, CVP and PAWP. There were no significant changes in heart rate during the changes in position before or after surgery. The results of our study showed a hemodynamic response similar to hemorrhage after placing the patients in a 20 degrees head-up position and improving

Background The number of obese pediatric patients requiring anesthesia is rapidly increasing. Although fentanyl is a commonly used narcotic during surgery, there is no pharmacokinetic (PK) data available for optimal dosing of fentanyl in adolescents with clinically severe obesity. Materials and Methods An IRB-approved exploratory pilot study was conducted in 6 adolescents aged 14 to 19 years undergoing bariatric surgery. Mean total body weight (TBW) and mean BMI were 137.4 ± 14.3 kg, and 49.6 ± 6.4 kg/m2 (99.5th BMI percentile), respectively. Fentanyl was dosed intravenously for intraoperative analgesia based on ideal body weight per standard of care. PK blood samples were drawn over a 24 hour post-dose period. Fentanyl PK parameters were calculated by non-compartmental analysis. Results Mean fentanyl AUC0–∞ was 1.5 ± 0.5 h*ng/mL. Systemic clearance of fentanyl was 1522 ± 310 mL/min and 11.2 ± 2.6 mL/min*kg TBW. Volume of distribution was 635 ± 282 L and 4.7 ± 2.1 L/kg TBW. While absolute clearance was increased, absolute volume of distribution was comparable to previously established adult values. Conclusions These results suggest that fentanyl clearance is enhanced in adolescents with clinically severe obesity while volume of distribution is comparable to previously published studies.

Ambulatory cleft lip repair after its acceptance in developed countries is also becoming popular in developing world. This study was performed to compares the outcomes of ambulatory cleft lip repair with the inpatient group for adult patients. Objectives were to compare outcome after ambulatory and inpatient cleft lip surgery for adults with respect to perioperative complications (Early: pain, oedema of upper lip, bleeding, nausea or vomiting, infection, dehiscence; Late: visible scar and white roll discrepancy), to compare the economic benefits, and evaluate patient satisfaction in terms of acceptance for ambulatory surgery. This comparative study is carried out in Plastic Surgery Department, King Edward Medical University, Mayo Hospital, Lahore. The study included 80 adult patients fulfilling inclusion criteria and were randomly divided into two groups, i.e., Ambulatory (Group-A, n=40) and Inpatient (Group-B, n=40). Those belonging to ambulatory group were worked up on OPD basis, advised to report on morning of surgery, operated under loco-regional anaesthesia and were discharged on same day. Patients of inpatient group were admitted two days before surgery, worked up in ward, operated under general anaesthesia and were discharged on 2nd day. Ambulatory cleft lip surgery can be easily performed under loco-regional anaesthesia. Perioperative complications between these groups were comparable. Hospital stay was significantly reduced in ambulatory surgery. The patients felt more satisfied after ambulatory than inpatient surgery. Ambulatory cleft lip repair for adults is as safe as inpatient surgery. It is dependable option and can be successfully performed in our setup. It should be considered whenever possible due to cost effectiveness, reduction of waiting lists, earlier discharge and better utilisation of hospital resources.

The aim of this study is to compare the hemodynamic effects of neostigmine-atropine combination and sugammadex in patients with cardiac problems undergoing noncardiac surgery. Prospective randomized study. In the operating room. Ninety patients with a class 2 or 3 cardiovascular disease according to the New York Heart Association classification and aged between 18 and 75 years undergoing noncardiac surgery were randomized. Group N (n = 45) received 0.03 mg/kg IV neostigmine when T2 appeared as measured with a nerve muscle stimulator. When heart rate was 5 beats/min (±10 beats/min) lower than the heart rate before administration of the medication, 0.5 mg IV atropine sulfate was given. Group S (n = 45) received 3 mg/kg IV sugammadex when T2 appeared as measured with a nerve muscle stimulator. Heart rate, mean systolic and diastolic blood pressures, and electrocardiographic alterations including the QTc (QT Fredericia and QT Bazett) were recorded. There were no significant differences between and within the groups in terms of QTc values. Sugammadex group had a significant decrease on heart rate 1 minute after the medication when compared to the measurement before the medication (P < .05). Heart rate and systolic blood pressure increased in neostigmine group 3 minutes after the medication and during postoperative measurements (P < .05). Sugammadex group had lower systolic, diastolic, and mean blood pressures and heart rate when compared to neostigmine group (P < .05). We suggest that sugammadex might be preferred as it provides more hemodynamic stability compared to neostigmine-atropine combination to reverse rocuronium-induced neuromuscular blockage in cardiac patients undergoing noncardiac surgery.

Despite scientific progress with regard to pain neuroscience, perioperative education tends to stick to the biomedical model. This may involve, for example, explaining the surgical procedure or 'back school' (education that focuses on biomechanics of the lumbar spine and ergonomics). Current perioperative education strategies that are based on the biomedical model are not only ineffective, they can even increase anxiety and fear in patients undergoing spinal surgery. Therefore, perioperative pain neuroscience education is proposed as a dramatic shift in educating patients prior to and following surgery for lumbar radiculopathy. Rather than focusing on the surgical procedure, ergonomics or lumbar biomechanics, perioperative pain neuroscience education teaches people about the underlying mechanisms of pain, including the pain they will feel following surgery. The primary objective of the study is to examine whether perioperative pain neuroscience education ('brain school') is more effective than classic back school in reducing pain and improving pain inhibition in patients undergoing surgery for spinal radiculopathy. A secondary objective is to examine whether perioperative pain neuroscience education is more effective than classic back school in: reducing postoperative healthcare expenditure, improving functioning in daily life, increasing return to work, and improving surgical experience (ie, being better prepared for surgery, reducing incongruence between the expected and actual experience) in patients undergoing surgery for spinal radiculopathy. A multi-centre, two-arm (1:1) randomised, controlled trial with 2-year follow-up. People undergoing surgery for lumbar radiculopathy (n=86) in two Flemish hospitals (one tertiary care, university-based hospital and one regional, secondary care hospital) will be recruited for the study. All participants will receive usual preoperative and postoperative care related to the surgery for lumbar radiculopathy. The experimental

Postoperative atrial fibrillation is a major cause of morbidity and mortality for stroke after cardiac surgery. Both systemic inflammation and oxidative stress play a role in the initiation of postoperative atrial fibrillation after cardiac surgery. The possible association between long-term intake of antioxidant-rich foods and postoperative atrial fibrillation incidence was examined in patients undergoing cardiac surgery. A total of 217 consecutive patients (74% were men; median age, 68.4 years) undergoing cardiac surgery, mainly coronary artery bypass grafting and valve replacement or repair, were recruited from January 2010 to September 2012. Total antioxidant capacity was measured in foods by the Trolox equivalent antioxidant capacity assay. The European Prospective Investigation into Cancer and Nutrition Food Frequency Questionnaire was used for dietary total antioxidant capacity assessment. The association among tertiles of dietary total antioxidant capacity and postoperative atrial fibrillation incidence was assessed using multivariable logistic analysis. The overall incidence of total arrhythmias and postoperative atrial fibrillation was 42.4% and 38.2%, respectively. In multivariable analysis, after adjustment for age, gender, use of hypoglycemic drugs, physical activity, education, previous diagnosis of atrial fibrillation, and total energy intake, patients in the highest tertile of dietary total antioxidant capacity had a lower risk of postoperative atrial fibrillation than patients in the 2 lowest tertiles (odds ratio, 0.46; 95% confidence interval, 0.22-0.95; P = .048). A restricted cubic spline transformation confirmed the nonlinear relationship between total antioxidant capacity (in continuous scale) and postoperative atrial fibrillation (P = .023). When considering only coronary artery bypass grafting, valve replacement/repair, and combined surgeries, the protective effect on postoperative atrial fibrillation of a diet rich in antioxidants was

Cataract-related vision impairment is an important public health issue that tends to affect older adults. Little is known about the association between older adults' social support networks and their likelihood of receiving cataract surgery. To determine if older adults with smaller social support networks are less likely to receive cataract surgery. Retrospective cohort study. The National Health and Aging Trends Study, a nationally representative US survey, administered annually from 2011 to 2015 to a cohort of Medicare beneficiaries 65 years and older with no cataract surgery prior to the start of the study. Multivariable logistic regression was performed to evaluate if the number of persons in an individual's social support network influenced whether that individual received cataract surgery during a given year of the study. Overall, 3448 participants were interviewed from 2011 to 2015 for a total of 9760 observations. Of these observations, 3084 (weighted, 38.81%; 95% CI, 37.28-40.35) were aged 70 to 74 years, 5211 (weighted, 52.32%; 95% CI, 50.19-54.44) were women; 5899 (weighted, 78.53%; 95% CI, 76.29-80.61) were white, 2249 (weighted, 9.55%; 95% CI, 8.45-10.78) were black, 537 (weighted, 7.18%; 95% CI, 5.88-8.73) were Hispanic, and 303 (weighted, 4.74%; 95% CI, 3.56-62.9) reported other races. Medicare beneficiaries with smaller social support networks (0-2 individuals) were less likely to receive cataract surgery in a given year (adjusted odds ratio, 0.60; 95% CI, 0.37-0.96) than those with larger support networks (≥3 individuals). The adjusted predicted proportion of Medicare beneficiaries undergoing cataract surgery was 4.7% (95% CI, 2.7%-6.7%) and 7.5% (95% CI, 6.9%-8.1%) for those with small and large social support networks, respectively. Having fewer non-spouse/partner family members in the support network was associated with decreased odds of receiving cataract surgery (adjusted odds ratio, 0.60; 95% CI, 0.43-0.85), but having spouses

Background: The body mass index (BMI) in the United States (US) is rising and may be contributing to increased anterior cruciate ligament reconstruction (ACLR) rates. It is currently unknown whether the BMI is increasing in patients who undergo ACLR. Purpose: To determine whether (1) the BMI changed in pediatric and adult patients who previously underwent ACLR or revision ACLR over a 10-year eligibility period, (2) the BMI changed at a greater rate in pediatric or adult patients, and (3) the percentage of overweight and obese patients in the ACLR population was different than that of the general overweight population. Study Design: Case series; Level of evidence, 4. Methods: A retrospective investigation of patients who underwent ACLR by 6 surgeons from June 3, 2005, to June 3, 2015, was conducted. Patients were divided into pediatric (<18 years) and adult (≥18 years) categories. BMI at the time of surgery was defined as underweight (<18.5 kg/m2), normal (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (≥30.0 kg/m2). Patients with an indeterminate BMI were excluded. Comparisons of overweight and obese patients were made with general population trends determined by the Centers for Disease Control and Prevention (CDC) in a single US state. Pearson (R) and Spearman (R s) correlations were used to determine correlations, Student t tests were used for 2-variable comparisons, analyses of variance were used for multivariable comparisons, and analyses of covariance were used for comparing linear relationships. Results: There were 1305 patients (733 male, 572 female; 409 pediatric, 896 adult) included. Adults requiring surgical revision demonstrated a strong positive correlation with respect to BMI over time (R s = 0.906, P < .01). No other statistically significant trends in the BMI over time were found. The proportion of overweight pediatric patients undergoing ACLR was significantly greater than that of the general overweight pediatric population (P < .05

Despite several experimental studies on the role of S100B and NSE in fractures, no studies on the influence of surgery on the biomarker serum levels have been performed yet. The serum levels of S100B and NSE were analysed in patients with fractures that were located in the spine (group 1, n = 35) or in the lower extremity (group 2, n = 32) pre- and post-operatively. The mean S100B serum level showed a significant increase (p = 0.04) post-surgery in the patients of group 1. In patients undergoing acute surgery (< 24 hours) the mean S100B serum level was 0.23 ± 0.22 μg L(-1) pre-operatively and 1.24 ± 1.38 μg L(-1) post-operatively. Likewise, the mean S100B serum level significantly increased in group 2 after surgery (p < 0.0001). In this group patients undergoing acute surgery showed a mean S100B serum level of 0.23 ± 0.14 μg L(-1) and 1.11 ± 0.73 μg L(-1) pre- and post-operatively. This study demonstrates significant alterations of the biomarker S100B serum levels in patients undergoing surgery. Higher S100B serum levels were found within 24 hours and might be related to the acute fracture. The NSE serum levels were unchanged and this biomarker may offer the probability to serve as a future outcome predictor in studies with patients with traumatic brain injury and additional extracerebral injuries.

Surgical stress creates a state of insulin resistance which may contribute to the development of hyperglycemia and, subsequently, postoperative complications. Consumption of an oral carbohydrate supplement before surgery may improve insulin sensitivity and reduce hyperglycemia. In this trial, we investigated the effects of carbohydrate supplementation on insulin resistance in coronary artery bypass graft and spinal decompression and fusion surgical patients. Twenty-six patients undergoing coronary artery bypass graft and 12 undergoing spine surgery were randomized to receive 800 mL of an oral carbohydrate supplement the evening before and 400 mL 2 hours before surgery (CHO) or to fasting per standard hospital protocol (FAST). Baseline and postoperative measurements of insulin sensitivity were assessed using the short insulin tolerance test and homeostasis model assessment (HOMA). Interleukin-6, C-reactive protein, and free fatty acid levels were determined at baseline, postoperatively, and 24, 48, and 72 hours after surgery. Adiponectin was measured at baseline. Subjective feelings of well-being were measured immediately before surgery, and intra- and postoperative outcomes were documented. Postoperative insulin sensitivity did not differ significantly between the FAST and CHO groups whether measured by the short insulin tolerance test (rate of disappearance of blood glucose: 0.29%/min vs 0.38%/min; 99% confidence interval [CI] for difference, -0.17 to 0.32, P = 0.41) or HOMA (insulin resistance at values >1: 2.3 vs 3.3; 99% CI for difference, -0.8 to 2.8, P = 0.14). Circulating blood glucose levels after surgery in the CHO group, 6.2 mmol/L, tended to be lower than the FAST group, 6.9 mmol/L (99% CI for difference, -1.7 to 0.25, P = 0.05) and postoperative β-cell function, measured by HOMA-β (impaired β-cell function at values <100%), tended to be higher in the CHO group, 87%, vs 47.5% in the FAST group (99% CI for difference, -9.4 to 88.4), but these

Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and⁄or anatomical anomalies. To determine the motor and anatomical causes of dysphagia. A total of 41 adults, followed at the Esophageal Atresia Clinic at Hôpital Saint-Luc (Montreal, Quebec), were approached to particpate in the present prospective study. Evaluation was completed using upper endoscopy, manometry and barium swallow for the participants who consented. The medical charts of respondents were systematically reviewed from the neonatal period to 18 years of age to assess medical and surgical history. All 41 patients followed at the clinic consented and were included in the study. Dysphagia was present in 73% of patients. Esophagogastroduodenoscopy was performed in 32 patients: hiatal hernia was present in 62% (n=20); esophageal diverticulum in 13% (n=4); macroscopic Barrett esophagus in 31% (n=10); and esophagitis in 19% (n=6). Histological esophagitis was present in 20% and intestinal metaplasia in 10%. There were no cases of dysplagia or adenocarcinoma. Esophageal manometry was performed on 56% of the patients (n=23). Manometry revealed hypomotility in 100% of patients and included an insufficient number of peristaltic waves in 96%, nonpropagating peristalsis in 78% and low-wave amplitude in 95%. Complete aperistalsis was present in 78%. The lower esophageal sphincter was abnormal in 12 (52%) patients, with incomplete relaxation the most common anomaly. Of the 41 patients, 29 (71%) consented to a barium swallow, which was abnormal in 13 (45%). The anomalies found were short esophageal dilation in 28%, delay in esophageal emptying in 14%, diverticula in 14% and stenosis in 7

Neonates undergoing surgery require analgesic medication to ameliorate acute pain. These medications produce negative side effects. Docosahexaenoic acid (DHA) has an antinociceptive effect in animals, but this has not been evaluated in human neonates. We evaluated the DHA effect on cumulative dose and duration of analgesics administered to neonates undergoing cardiovascular surgery. A secondary analysis was performed with data from a clinical trial, in which enteral DHA was administered perioperatively compared with sunflower oil (SO). Present study assessed the antinociceptive effect of DHA by measuring the cumulative dose and duration of analgesics administered during postoperative stay in a neonatal intensive care unit. Multivariate linear regression models were performed. Seventeen neonates received DHA and 18 received SO in the control group. Compared with the control group, the DHA group received lower cumulative dose (14.6 ± 2.2 vs. 25.2 ± 4.8 μg/kg, p = 0.029) and shorter duration of buprenorphine (2 days (1-8) vs. 4.5 days (1-12); p = 0.053). After adjusting for confounders, the DHA group received significantly lesser buprenorphine (β = -27 μg/kg, p = 0.028; R2 model = 0.90) for shorter duration (β = -9 days, p = 0.003; R2 model = 0.94). No differences in fentanyl or ketorolac were detected. Buprenorphine administration was reduced in neonates who received DHA, suggesting that DHA likely has analgesic effects. © 2016 S.

Since the surgery for congenital heart disease (CHD) is considered highly risky, appropriate postoperative care is crucial. After the surgery, children are often discharged with unhealed wounds, incomplete recovery, and continuing pain. Health education programs based on empowerment education model can assist clients to develop skills in self-management. This study aimed to evaluate the effectiveness of an empowerment health education program for improving caregiving knowledge, caring behaviors, and self-efficacy of parents caring for children after corrective surgery for CHD. This prospective clinical trial enrolled pediatric patients undergoing surgical correction for CHD. Patients were divided into two groups: the control group (n = 42), which received the standard education program, and the intervention group (n = 44), which participated in the empowerment theory-based education program. We collected data on left ventricular ejection fraction (LVEF); peripheral oxygen saturation (SpO2); New York Heart Association classification of the patients; and the parents' caregiving knowledge, caring behaviors, and self-efficacy before surgery and one month and three months after surgery. At one month and three months after surgery, the intervention group scored higher than the control group in caregiving knowledge, caring behavior, and self-efficacy. By the third month after surgery, the intervention group had significantly higher values of LVEF and SpO2 than the control group. © The Author(s) 2015.

To analyze perceived health status and other health-related indicators in the adult population in Granada (Spain) undergoing an eviction process from their homes, whether rented or owned, in comparison with health indicators in the general adult population in Andalusia. A cross-sectional survey was administered by trained staff. The survey included instruments from the Andalusian Health Survey 2011 for measuring variables related to physical and mental health, as well as health-related habits. We compared the results with those obtained from the Andalusian general population through the Andalusian Health Survey. A bivariate analysis using the χ2 test and a multivariate logistic regression analysis were conducted. We obtained a total sample of 205 people in the process of eviction. A total of 59.5% (n=122) were women, and 40.5% (n=83) were men. Participants were more likely to have poor health (odds ratio [OR]: 12.63, 95% confidence interval [95%CI]: 8.74-18.27), have cardiovascular diseases (OR: 3.08; 95%CI: 1.54- 6.16), or to smoke (OR: 1.68; 95% CI: 1.21-2.33) compared with the Andalusian general population. Most of the health indicators analyzed showed a worse outcome for women undergoing an eviction process. Our results suggest that, in the current context of economic crisis, people undergoing a process of eviction in Granada and its metropolitan area show poorer health than the Andalusian general population. Further research is needed on health and evictions from different methodological approaches, for a better understanding of the topic. Copyright © 2015 SESPAS. Published by Elsevier Espana.

The aim of this study was to assess the preoperative nutritional status of patients undergoing thoracic surgery using different nutritional tools. . We conducted a prospective study on a sample of 43 thoracic patients, including 23 with neoplasms and 20 with non-neoplastic pathology who underwent thoracic surgery procedures between July-September 2011, in the Thoracic Surgery Clinic in Iaşi. Weight and height were measured and body mass index (BMI) was calculated. WHO classification for BMI categories was used. Preoperative serum level of transthyretin (TTR) and demographic data (gender, age) were also assessed. All patients were examined by the Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002). After performing SGA, 67.9% of the patients were well-nourished, 21.4% were moderately or suspected of being malnourished and 10.7% were severely malnourished. The level of TTR was significantly lower in the moderately or severely malnourished group, compared to those considered well-nourished. According to NRS-2002, 42.9% of the patients were considered at nutritional risk. The level of TTR of these patients was lower than the level of TTR of the patients without nutritional risk, but without statistical significance. Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002) are useful in identifying patients with nutritional risk, so that appropriate nutritional management could be initialised even before surgery.

Surgery-Independent Language Function Decline in Patients Undergoing Awake Craniotomy.

Despite selection process before awake-craniotomy, some patients experience an unexpected decline in language functions in the operating room (OR), compared with their baseline evaluation, which may impair their functional monitoring. To investigate this phenomenon we prospectively compared language function the day before surgery and on entrance to the OR. Data were collected prospectively from consecutive patients undergoing awake-craniotomy with intraoperative cortical mapping for resection of gliomas affecting language areas. Language functions of 79 patients were evaluated and compared 1-2 days before surgery and after entering the OR. Changes in functional linguistic performance were analyzed with respect to demographic, clinical, and pathologic characteristics. There was a significant decline in language function, beyond sedation effect, after entering the OR, (from median/interquartile range: 0.94/0.72-0.98 to median/interquartile range: 0.86/0.51-0.94; Z = -7.19, P < 0.001). Univariate analyses revealed that this decline was related to age, preoperative Karnofsky Performance Scale, tumor location, tumor pathology, and preexisting language deficits. Multivariate stepwise regression identified tumor pathology and the presence of preoperative language deficit as significant independent predictors for this functional decline. Patients undergoing awake-craniotomy may experience a substantial decline in language functioning after entering the OR. Tumor grade and the presence of preoperative language deficits were significant risk factors for this phenomenon, suggesting a possible relation between cognitive reserve, psychobehavioral coping abilities and histologic features of a tumor involving language areas. Capturing and identifying this unique population of patients who are prone to experience such language decline may improve our ability in the future to select patients eligible for awake-craniotomy.

The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed as an extensive question bank with multiple health domains that could be utilized for computerized adaptive testing (CAT). In the present study, we investigated the use of the PROMIS Physical Function CAT (PROMIS PF CAT) in an otherwise healthy population scheduled to undergo surgery for meniscal injury with the hypotheses that (1) the PROMIS PF CAT would correlate strongly with patient-reported outcome instruments that measure physical function and would not correlate strongly with those that measure other health domains, (2) there would be no ceiling effects, and (3) the test burden would be significantly less than that of the traditional measures. Patients scheduled to undergo meniscal surgery completed the PROMIS PF CAT, Knee injury and Osteoarthritis Outcome Score (KOOS), Marx Knee Activity Rating Scale, Short Form-36 (SF-36), and EuroQol-5 Dimension (EQ-5D) questionnaires. Correlations were defined as high (≥0.7), high-moderate (0.61 to 0.69), moderate (0.4 to 0.6), moderate-weak (0.31 to 0.39), or weak (≤0.3). If ≥15% respondents to a patient-reported outcome measure obtained the highest or lowest possible score, the instrument was determined to have a significant ceiling or floor effect. A total of 107 participants were analyzed. The PROMIS PF CAT had a high correlation with the SF-36 Physical Functioning (PF) (r = 0.82, p < 0.01) and KOOS Sport (r = 0.76, p < 0.01) scores; a high-moderate correlation with the KOOS Quality-of-Life (QOL) (r = 0.63, p < 0.01) and EQ-5D (r = 0.62, p < 0.01) instruments; and a moderate correlation with the SF-36 Pain (r = 0.60, p < 0.01), KOOS Symptoms (r = 0.57, p < 0.01), KOOS Activities of Daily Living (ADL) (r = 0.60, p < 0.01), and KOOS Pain (r = 0.60, p < 0.01) scores. The majority (89%) of the patients completed the PROMIS PF CAT after answering only 4 items. The PROMIS PF CAT had no floor or ceiling effects, with 0% of the

Preoperative hyponatremia adversely impacts outcomes of cardiothoracic surgery. However, in patients with chronic kidney disease, the association of sodium levels on postoperative events has never been evaluated. We investigated the impact of preoperative hyponatremia on outcomes after cardiac surgery in patients with non-dialysis-dependent chronic kidney disease. Primary endpoints were operative mortality and acute kidney injury requiring dialysis. Secondary endpoints were major infection and long-term survival. The study is observational and includes all patients with stage III-IV chronic kidney disease (non-dialysis) undergoing cardiac surgery between February 2000-January 2016. Patients were stratified into 2 groups by preoperative sodium levels: Na <135 mEq/L; Na ≥135 mEq/L. There were 1008 patients (mean eGFR 43 ± 14 mL/min/1.73 m 2 ): 92 (9%) in the low sodium group. Patients with low sodium had higher operative mortality (p=0.0004), need for new dialysis (p=0.0008), and infection (p=0.002). Predictors of operative mortality were: EuroSCORE (HR1.03; CI 1.02-1.05 ; p<0.0001); Decreasing values of sodium (HR 1.14; CI 1.07-1.2; p=0.0002); and decreasing values of GFR (HR1.01; CI 1.003-1.03; p=0.007). Sodium below 135 mEq/L was independently associated with increased need for dialysis (HR1.3; CI 1.1-1.7; p= 0.0008). By linear regression, decreasing values of preoperative sodium were proportionate to the incidence of operative mortality (p<0.0001) and need for dialysis (p<0.0001). Preoperative hyponatremia is a predictor of increased mortality as well as other adverse events in patients with non- dialysis dependent chronic kidney disease undergoing cardiac surgery. These findings are similar to those in hyponatremic patients without kidney disease. Copyright © 2018. Published by Elsevier Inc.

The preoperative education, which occurs in preoperative patient consultations, is an important part of the surgical nurse's profession. These consultations may be the building blocks of a partnership that facilitates communication between patient and nurse. The aim of the study was to describe topics and structure and documentation in preoperative nursing consultations with patients undergoing surgery for colorectal cancer. The study was based on analysis of consultations between seven patients and nurses at a Swedish university hospital. The preplanned preoperative consultations were audio-recorded and transcribed verbatim. The structure of the consultations was described in terms of phases and the text was analysed according to a manifest content analysis RESULTS: The consultations were structured on an agenda that was used variously and communicating different topics in an equally varied manner. Seven main topics were found: Health status, Preparation before surgery, Discovery, Tumour, Operation, Symptoms and Recovery after surgery. The topic structure disclosed a high number of subtopics. The main topics 'Discovery', 'Tumour' and 'Symptoms' were only raised by patients and occupied only 11% of the discursive space. Documentation was sparse and included mainly task-oriented procedures rather than patients' worries and concerns. There was no clear structure regarding preoperative consultation purpose and content. Using closed questions instead of open is a hindrance of developing a dialogue and thus patient participation. Preoperative consultation practice needs to be strengthened to include explicit communication of the consultations' purpose and agenda, with nurses actively discussing and responding to patients' concerns and sensitive issues. The results of the study facilitate the development of methods and structure to support person-centred communication where the patient is given space to get help with the difficult issues he/she may have when undergoing

With the increasing aging population, the number of very elderly patients (age ≥80 years) undergoing emergency operations is increasing. Evaluating patient-specific risk factors for postoperative morbidity and mortality in the acute care surgery setting is crucial to improving outcomes. We hypothesize that sarcopenia, a severe depletion of skeletal muscles, is a predictor of morbidity and mortality in very elderly patients undergoing emergency surgery. A total of 170 patients older than the age of 80 underwent emergency surgery between 2008 and 2010 at a tertiary care facility; 100 of these patients had abdominal computed tomography images within 30 days of the operation that were adequate for the assessment of sarcopenia. The impact of sarcopenia on the operative outcomes was evaluated using both univariate and multivariate analysis. The mean patient age was 84 years, with an in-hospital mortality of 18%. Sarcopenia was present in 73% of patients. More sarcopenic patients had postoperative complications (45% sarcopenic versus 15% nonsarcopenic, P = .005) and more died in hospital (23 vs 4%, P = .037). There were no differences in duration of stay or requirement for intensive care unit postoperatively. After we controlled for confounding factors, increasing skeletal muscle index (per incremental cm(2)/m(2)) was associated with decreased in-hospital mortality (odds ratio ∼0.834, 95% confidence interval 0.731-0.952, P = .007) in multivariate analysis. Sarcopenia was independently predictive of greater complication rates, discharge disposition, and in-hospital mortality in the very elderly emergency surgery population. Using sarcopenia as an objective tool to identify high-risk patients would be beneficial in developing tailored preventative strategies and potentially resource allocation in the future.

The reported incidence of acute chest syndrome (ACS) in children with sickle cell disease (SCD) is 15% to 20%. Our current objective was to assess risk factors and morbidity associated with ACS. The authors reviewed the outcome of children with SCD undergoing abdominal surgery over a 10-year period. From 1991 to 2003, 60 children underwent laparoscopic cholecystectomy (LC; n = 29), laparoscopic splenectomy (LS; n = 28), or both (LB; n = 3). Mean age was 8.6 (0.7 to 20) years, and 35 (58%) were boys. Fifty-four (90%) had a preoperative hemoglobin greater than 10 g/dL, but only 22 (37%) received routine oxygen after surgery. No surgery was converted to an open procedure. Four children (6.6%), all of whom underwent either LS or LB, had ACS associated with an increased length of stay (7.4 +/- 2.4 days) but no mortality. Factors associated with the development of ACS were age (3.0 +/- 1.7 v 9.4 +/- 5.7 years; P =.03), weight (12.1 +/- 3.0 v 32.6 +/- 18.2 kg; P =.04), operative blood loss (3.2 +/- 0.5 v 1.4 +/- 1.2 mL/kg; P =.03), and final temperature in the operating room (OR; 36.2 +/- 0.4 v 37.6 +/- 0.4 degrees C; P =.01). ACS was not significantly related to duration of surgery, OR fluids, or oxygen usage. Younger children with greater blood and heat loss during surgery appear more prone to ACS. Splenectomy also seems to increase the risk of ACS. The authors' current incidence (6.6%) of ACS in children with SCD undergoing abdominal surgery is much lower than previously reported. This may be explained by the aggressive use of preoperative blood transfusion or more routine use of laparoscopy.

Objective To systematically review the effects of preoperative and postoperative resistance exercise training on the recovery of physical function in patients undergoing abdominal surgery for cancer. Data sources A systematic review of English articles using Medline, Physiotherapy Evidence Database, CINAHL and the Cochrane Library electronic databases was undertaken. Eligibility criteria for selecting studies Studies were included if they used a randomised, quasi-randomised or controlled trial study design and compared the effects of a muscle-strengthening exercise intervention (±other therapy) with a comparative non-exercise group; involved adult participants (≥18 years) who had elected to undergo abdominal surgery for cancer; and used muscle strength, physical function, self-reported functional ability, range of motion and/or a performance-based test as an outcome measure. Results Following screening of titles and abstracts of the 588 publications retrieved from the initial search, 24 studies met the inclusion criteria and were accessed for review of the full-text version of the article, and 2 eligible studies met the inclusion criteria and were included in the review. One exercise programme was undertaken preoperatively and the other postoperatively, until discharge from hospital. The exercise interventions of the included studies were performed for five and eight sessions, respectively. There were no differences between groups in either study. Conclusion The only two studies designed to determine whether preoperative or postoperative resistance muscle-strengthening exercise programmes improved or negatively affected physical function outcomes in patients undergoing abdominal surgery for cancer provide inconclusive results.

Respiratory problems occur more frequently in patients who undergo open heart surgery. Intraoperative and postoperative ventilation strategies can prevent these complications and reduce mortality. We hypothesized that PCV would have better effects on gas exchange, lung mechanics and hemodynamics compared to VCV in CABG surgery. Our primary outcome was to compare the PaO 2 /FiO 2 ratio. Patients were randomized into two groups, (VCV, PCV) consisting of 30 individuals each. Two patients were excluded from the study. I/E ratio was adjusted to 1:2 and, RR:10/min fresh air gas flow was set at 3L/min in all patients. In the VCV group TV was set at 8 mL/kg of the predicted body weight. In the PCV group, peak inspiratory pressure was adjusted to the same tidal volume with the VCV group. PaO2/FiO2 was found to be higher with PCV at the end of the surgery. Time to extubation and ICU length of stay was shorter with PCV. Ppeak was similar in both groups. Pplateau was lower and Pmean was higher at the and of the surgery with PCV compared to VCV. The hemodynamic effects of both ventilation modes were found to be similar. PVC may be preferable to VCV in patients who undergo open heart surgery. However, it would be convenient if our findings are supported by similar studies.

Cardiac complications are not uncommon in patients undergoing non-cardiac surgery, especially in patients with coronary artery disease (CAD) or at high risk of CAD. Perioperative cardiac complications can lead to mortality and morbidity, as well as higher costs for patient care. Nitrates, which are among the most commonly used cardiovascular drugs, perform the function of decreasing cardiac preload while improving cardiac blood perfusion. Sometimes, nitrates are administered to patients undergoing non-cardiac surgery to reduce the incidence of cardiac complications, especially for patients with CAD. However, their effects on patients' relevant outcomes remain controversial. • To assess effects of nitrates as compared with other interventions or placebo in reducing cardiac risk (such as death caused by cardiac factors, angina pectoris, acute myocardial infarction, acute heart failure and cardiac arrhythmia) in patients undergoing non-cardiac surgery.• To identify the influence of different routes and dosages of nitrates on patient outcomes. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Chinese BioMedical Database until June 2014. We also searched relevant conference abstracts of important anaesthesiology or cardiology scientific meetings, the database of ongoing trials and Google Scholar.We reran the search in January 2016. We added three potential new studies of interest to the list of 'Studies awaiting classification' and will incorporate them into our formal review findings for the review update. We included randomized controlled trials (RCTs) comparing nitrates versus no treatment, placebo or other pharmacological interventions in participants (15 years of age and older) undergoing non-cardiac surgery under any type of anaesthesia. We used standard methodological procedures as expected by Cochrane. Two review authors selected trials, extracted data from included studies and assessed risk of bias. We

The purpose of our study was to estimate the incidence of SSI (Surgical site infection) and the effect of COLA (contamination, obesity, laparotomy and ASA grade) score on SSI in patients undergoing rectal surgical procedures for rectal cancer. A total of 92 patients who underwent operation for rectum cancer were enrolled in this study. Wound surveillance was performed in all patients by a staff surgeon identified infected wounds during the hospital stay, and collected information for up to 30 days after operation. The overall rate of incisional SSI and organ/space SSI was 22.8% and 7.6% respectively. Surgical site infection rates were 14.2%, 20.58%, 40.7%, 57.1% for COLA 1,2,3 and 4 scores respectively. The area under the receiver/ operator characteristic curve for the score was 0,660. COLA scoring systems predict, with reasonable accuracy, the risk of SSI in rectal cancer patients undergoing elective rectal surgery.

Retrospective database analysis. To evaluate outcomes of human immunodeficiency virus (HIV) positive patients after cervical spine surgery. Highly active antiretroviral medications have qualitatively altered the natural history of HIV, thus increasing the number of HIV-positive patients seeking treatment for chronic degenerative conditions. Minimal data exist on HIV patients undergoing degenerative cervical spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Hospitalizations were identified using International Classification of Diseases Ninth Revision, Clinical Modification (ICD-9-CM) procedural codes for cervical spine surgery and diagnoses codes for degenerative conditions of the cervical spine, and HIV. Statistical analysis was conducted to evaluate associations between HIV status and perioperative complications. A total of 1,602,129 patients underwent degenerative cervical spine surgery, of which 3700 patients (0.23%) had HIV. The prevalence of HIV increased over the study period from 0.19% to 0.33% (P < 0.001). Patients with HIV were younger (48.6 yrs vs. 53.4 yrs, P < 0.001) and more likely to be male (P < 0.001). HIV patients had significantly greater odds of having chronic pulmonary disease, liver disease, and drug abuse. Unadjusted analysis did not reveal increased rate of acute complications among HIV-positive patients compared with negative controls (3.8% vs. 3.7%, P = 0.62). Multivariate analysis did not identify HIV as a significant predictor of complication (odds ratio = 1.04, P = 0.84). HIV was associated with a 1.5 day increased length of stay AND 1.29 fold increase in median costs compared with controls ($14,551 vs. 18,846, P < 0.001). The prevalence of HIV patients undergoing degenerative cervical spine surgery is increasing. A diagnosis of HIV was not associated with an increased risk of perioperative complication among patients undergoing degenerative cervical spine surgery. Further clinical

The effect of mannitol on intraoperative brain relaxation in patients undergoing supratentorial tumor surgery: study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background The risk of brain swelling after dural opening is high in patients with midline shift undergoing supratentorial tumor surgery. Brain swelling may result in increased intracranial pressure, impeded tumor exposure, and adverse outcomes. Mannitol is recommended as a first-line dehydration treatment to reduce brain edema and enable brain relaxation during neurosurgery. Research has indicated that mannitol enhanced brain relaxation in patients undergoing supratentorial tumor surgery; however, these results need further confirmation, and the optimal mannitol dose has not yet been established. We propose to examine whether different doses of 20% mannitol improve brain relaxation in a dose-dependent manner when administered at the time of incision. We will examine patients with preexisting mass effects and midline shift undergoing elective supratentorial brain tumor surgery. Methods This is a single-center, randomized controlled, parallel group trial that will be carried out at Beijing Tiantan Hospital, Capital Medical University. Randomization will be achieved using a computer-generated table. The study will include 220 patients undergoing supratentorial tumor surgery whose preoperative computed tomography/magnetic resonance imaging results indicate a brain midline shift. Patients in group A, group B, and group C will receive dehydration treatment at incision with 20% mannitol solutions of 0.7, 1.0, and 1.4 g/kg, respectively, at a rate of 600 mL/h. The patients in the control group will not receive mannitol. The primary outcome is an improvement in intraoperative brain relaxation and dura tension after dehydration with mannitol. Secondary outcomes are postoperative outcomes and the incidence of mannitol side effects. Discussion The aim of this study is to determine the optimal dose of 20% mannitol for intraoperative infusion. We will examine brain relaxation and outcome in patients undergoing supratentorial tumor surgery. If our results are positive, the study

The Canadian Cardiovascular Society Guidelines Committee and key Canadian opinion leaders believed there was a need for up to date guidelines that used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system of evidence assessment for patients who undergo noncardiac surgery. Strong recommendations included: 1) measuring brain natriuretic peptide (BNP) or N-terminal fragment of proBNP (NT-proBNP) before surgery to enhance perioperative cardiac risk estimation in patients who are 65 years of age or older, are 45-64 years of age with significant cardiovascular disease, or have a Revised Cardiac Risk Index score ≥ 1; 2) against performing preoperative resting echocardiography, coronary computed tomography angiography, exercise or cardiopulmonary exercise testing, or pharmacological stress echocardiography or radionuclide imaging to enhance perioperative cardiac risk estimation; 3) against the initiation or continuation of acetylsalicylic acid for the prevention of perioperative cardiac events, except in patients with a recent coronary artery stent or who will undergo carotid endarterectomy; 4) against α 2 agonist or β-blocker initiation within 24 hours before surgery; 5) withholding angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker starting 24 hours before surgery; 6) facilitating smoking cessation before surgery; 7) measuring daily troponin for 48 to 72 hours after surgery in patients with an elevated NT-proBNP/BNP measurement before surgery or if there is no NT-proBNP/BNP measurement before surgery, in those who have a Revised Cardiac Risk Index score ≥1, age 45-64 years with significant cardiovascular disease, or age 65 years or older; and 8) initiating of long-term acetylsalicylic acid and statin therapy in patients who suffer myocardial injury/infarction after surgery.

Gastroesophageal reflux disease is a chronic disease of high prevalence in Western countries, with negative effects on quality of life. Surgery is indicated for patients with intolerance to continuous medication, prolonged treatment or control, or in complicated forms of the disease. To evaluate the quality of life of patients undergoing surgery by videolaparoscopy for gastroesophageal reflux disease treatment. Sample comprised 43 patients of both genders (mean age = 51.4 years). For quality of life evaluation was made using the questionnaire Gastroesophageal Reflux Disease Health Related Quality of Life, translated and validated into Portuguese. Data were analyzed by Epi Info version 3.5.1, using Duncan test and Pearson's correlation coefficient, with 5% for null hypothesis (p ≤ 0.05). Over 50% of participants showed good quality of life (scores <5 of the questionnaire), more than 90% indicated satisfaction with their health. A significant positive correlation between most variables related to heartburn and the time after surgery was observed (p ≤ 0.05). Patients presented good quality of life and high level of satisfaction with their postoperative condition.

Red blood cell (RBC) transfusion is frequently required in pediatric cardiac surgery and is associated with altered outcome and increased costs. Determining which factors predict transfusion in this context will enable clinicians to adopt strategies that will reduce the risk of RBC transfusion. This study aimed to assess predictive factors associated with RBC transfusion in children undergoing low-risk cardiac surgery with cardiopulmonary bypass (CPB). Children undergoing surgery to repair ventricular septal defect or atrioventricular septal defect from 2006 to 2011 were included in this retrospective study. Demography, preoperative laboratory testing, intraoperative data, and RBC transfusion were reviewed. Univariate and multivariate logistic regression analysis were used to define factors that were able to predict RBC transfusion. Then, we employed receiver operating characteristic analysis to design a predictive score. Among the 334 children included, 261 (78%) were transfused. Age (<18 months), priming volume of the CPB (>43 mL/kg), type of oxygenator used, minimal temperature reached during CPB (<32°C), and preoperative hematocrit (<34%) were independently associated with RBC transfusion in the studied population. A predictive score 2 or greater was the best predictor of RBC transfusion. The present study identified several factors that were significantly associated with perioperative RBC transfusion. Based on these factors, we designed a predictive score that can be used to develop a patient-based blood management program with the aim of reducing the incidence of RBC transfusion.

Pectus excavatum (PEx) is one of the most common congenital chest wall deformities. Depending on the severity, presentation of PEx may range from minor cosmetic issues to disabling cardiopulmonary symptoms. The effect of PEx on adult patients has not been extensively studied. Symptoms may not occur until the patient ages, and they may worsen over the years. More recent publications have implied that PEx may have significant cardiopulmonary implications and repair is of medical benefit. Adults presenting for PEx repair can undergo a successful repair with a minimally invasive “Nuss” approach. Resolution of symptoms, improved quality of life, and satisfying results are reported.

A simple, objective and accurate way of grouping children undergoing surgery into clinically relevant risk groups is needed. The purpose of this study, is to develop and validate a preoperative risk classification system for postsurgical 30-day mortality for children undergoing a wide variety of operations. The National Surgical Quality Improvement Project-Pediatric participant use file data for calendar years 2012–2014 was analyzed to determine preoperative variables most associated with death within 30 days of operation (D30). Risk groups were created using classification tree analysis based on these preoperative variables. The resulting risk groups were validated using 2015 data, and applied to neonates and higher risk CPT codes to determine validity in high-risk subpopulations. A five-level risk classification was found to be most accurate. The preoperative need for ventilation, oxygen support, inotropic support, sepsis, the need for emergent surgery and a do not resuscitate order defined non-overlapping groups with observed rates of D30 that vary from 0.075% (Very Low Risk) to 38.6% (Very High Risk). When CPT codes where death was never observed are eliminated or when the system is applied to neonates, the groupings remained predictive of death in an ordinal manner. PMID:29351327

The purpose of this study was to determine the efficacy of a cognitive-behavioral-based physical therapy (CBPT) program for improving outcomes in patients after lumbar spine surgery. A randomized controlled trial was conducted on 86 adults undergoing a laminectomy with or without arthrodesis for a lumbar degenerative condition. Patients were screened preoperatively for high fear of movement using the Tampa Scale for Kinesiophobia. Randomization to either CBPT or an education program occurred at 6 weeks after surgery. Assessments were completed pretreatment, posttreatment and at 3-month follow-up. The primary outcomes were pain and disability measured by the Brief Pain Inventory and Oswestry Disability Index. Secondary outcomes included general health (SF-12) and performance-based tests (5-Chair Stand, Timed Up and Go, 10-Meter Walk). Multivariable linear regression analyses found that CBPT participants had significantly greater decreases in pain and disability and increases in general health and physical performance compared with the education group at the 3-month follow-up. Results suggest a targeted CBPT program may result in significant and clinically meaningful improvement in postoperative outcomes. CBPT has the potential to be an evidence-based program that clinicians can recommend for patients at risk for poor recovery after spine surgery. This study investigated a targeted cognitive-behavioral-based physical therapy program for patients after lumbar spine surgery. Findings lend support to the hypothesis that incorporating cognitive-behavioral strategies into postoperative physical therapy may address psychosocial risk factors and improve pain, disability, general health, and physical performance outcomes.

Bariatric surgery is an evidence-based treatment for severe obesity; however, the unique developmental and psychosocial needs of young adults often complicate care and, as yet, are not well understood. We sought to identify themes in young adult patients undergoing bariatric surgery regarding: 1) the psychosocial experiences of obese young adults (18 to 24) seeking bariatric surgery; 2) the experiences during the preoperative bariatric surgery process and 3) the postoperative experiences of young adult patients. In-depth, semistructured individual interviews were conducted with 13 young adult bariatric patients who were seeking or had undergone bariatric surgery within the past 5 years. Interviews were analyzed using a qualitative methodology. We found the following themes in our analyses: 1) the impact of relationships (with families and healthcare providers) on the bariatric healthcare experience; 2) preoperative experiences by young adults prior to undergoing surgery and 3) postoperative reflections and challenges experienced by young adult patients. Results revealed that patients' experiences appear to encompass impact on familial relationships, needs sought to be fulfilled by healthcare providers, and various preoperative and postoperative psychosocial concerns. By understanding the experiences of young adults, healthcare providers might be able to provide better care for these patients. Copyright © 2017 Diabetes Canada. Published by Elsevier Inc.

Perioperative risk associated with pulmonary hypertension (PH) in patients undergoing non-cardiac surgery (NCS) remains poorly defined. We report perioperative outcomes in a large cohort of patients undergoing NCS, comparing those with and without PH. Patients undergoing NCS at our institution between January 2002 and December 2006, were cross matched with a Right Heart Catheterization (RHC) database for the same period. Patients were excluded if they were <18 years old and if they underwent cardiac surgery prior to NCS or minor procedures using local anesthesia or sedation. Controls were defined as patients who underwent similar NCS with mean pulmonary arterial pressure (MPAP) ≤ 25 mmHg. 173 patients underwent RHC and NCS during the specified period and were included in the analysis. Of these 96 (55%) had PH. Mean pulmonary arterial pressure (p = 0.001), American Association of Anesthesiology Class (p = 0.02), and chronic renal insufficiency (p = 0.03) were determined as independent risk factors for post-operative morbidity. Patients with PH were more likely to develop congestive heart failure (p < 0.001; OR: 11.9), hemodynamic instability (p < 0.002), sepsis (p < 0.0005), and respiratory failure (p < 0.004). Patients with PH needed longer ventilatory support (p < 0.002), stayed longer in the ICU (p < 0.04), and were more frequently readmitted to the hospital within 30 days (p < 008; OR 2.4). In addition to the traditionally known risk factors for outcomes after NCS such as coronary artery disease, diabetes mellitus, chronic renal insufficiency, American Society of Anesthesiology class, the presence of underlying PH can have a significant negative impact on perioperative outcomes.

Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. A retrospective analysis of 43 high-risk patients who underwent concomitant surgical aortic valve replacement and mitral valve surgery from 2008 to 2012 was performed. Immediate and long term survival were assessed. There were 43 high-risk patients with severe aortic stenosis undergoing concomitant surgical aortic valve replacement and mitral valve surgery. The average age was 80 ± 6 years old. Nineteen (44%) patients had prior cardiac surgery, 15 (34.9%) patients had chronic obstructive lung disease, and 39 (91%) patients were in congestive heart failure. The mean Society of Thoracic Surgeons Predicted Risk of Mortality for isolated surgical aortic valve replacement for the cohort was 10.1% ± 6.4%. Five patients (11.6%) died during the index admission and/or within thirty days of surgery. Mortality rate was 25% at six months, 35% at 1 year and 45% at 2 years. There was no correlation between individual preoperative risk factors and mortality. High-risk patients with severe aortic stenosis and mitral valve disease undergoing concomitant surgical aortic valve replacement and mitral valve surgery may have similar long term survival as that described for such patients undergoing TAVR. Surgical correction of double valvular disease in this patient population may not confer mortality benefit compared to TAVR alone.

Interatrial block (IAB) is a well-known entity that is associated with an increased risk of atrial fibrillation (AF). This association is called Bayes' syndrome. The aim of our study was to define the prevalence of IAB among patients younger than 65 years undergoing cardiac surgery and determine whether there is an association between the presence of interatrial conduction delay and postoperative atrial fibrillation (POAF). A total of 207 patients were enrolled. Partial IAB was defined as P-wave>120ms. Advanced IAB was defined as P-wave>120ms+biphasic morphology in the inferior leads. Ocurrence of POAF was assessed and a comparative analysis was conducted between patients that did and did not develop AF. IAB prevalence was 78.3% (partial 66.2%, advanced 12.1%). POAF occurred in 28.5% of all patients, and was more frequent among patients with advanced IAB (44%) compared to 27.7% and 24.4% of POAF among patients with partial IAB and without IAB, respectively. Patients who developed POAF were significantly older, had significantly higher NTproBNP, higher prevalence of atrial enlargement and thyroid disease. After multivariate analysis, advanced IAB was found to be independently associated with POAF. IAB is a frequent finding among patients undergoing cardiac surgery. According to our results, advanced IAB is independently associated with POAF in younger patients (<65 years) undergoing cardiac surgery.

To assess the incidence of renal injury among pediatric patients who received aprotinin while undergoing cardiac surgery compared with those who received ε-aminocaproic acid (EACA). A retrospective observational study. A single academic center. Pediatric cardiac patients who had cardiopulmonary bypass and received aprotinin or EACA. Patients undergoing pediatric cardiac surgery received aprotinin from 2005 to 2007 and EACA from 2008 to 2009. The primary outcome was acute kidney injury (AKI) defined as serum Cr elevation at discharge more than 1.5 times the baseline value. Secondary outcomes included bleeding, blood transfusion, and the volume of chest tube drainage in the first 24 hours postoperatively. One hundred seventy-eight patients met inclusion criteria; 120 patients received aprotinin, and 58 patients received EACA. These 2 groups did not differ significantly in age, weight, or duration of cardiac bypass. Logistic regression analysis, adjusted for confounding variables (ie, baseline Cr, sex, age, CPB time, inotropic support and vasopressors), showed a higher odds of suffering AKI at discharge with the usage of aprotinin (odds ratio = 4.7; 95% confidence interval, 1.1-19.5; p = 0.03). The volume of the first 24 hours of chest tube drainage was not significantly different between groups, as well as packed red blood cells and cryoprecipitate units. However, fresh frozen plasma and platelets showed statistically significant differences with more transfusion in the EACA group. In this retrospective study, the authors observed a higher odds of AKI for aprotinin usage compared with EACA, suggesting that the known concern for adults with adverse kidney effects with aprotinin is also appropriate for pediatric patients.

The purpose was to understand the processes Hispanic parents undergo in managing postoperative care of children after routine surgical procedures. Sixty parents of children undergoing outpatient surgery were interviewed. Data were analyzed using grounded theory methodology. Parents experienced five subprocesses that comprised the overall process of caring for a child after routine surgery: (a) becoming informed; (b) preparing; (c) seeking reassurance; (d) communicating with one's child; and (e) making pain management decisions. Addressing cultural factors related to pain management in underserved families may instill greater confidence in managing pain. © 2015, Wiley Periodicals, Inc.

To investigate the use of the risk-adjusted sequential probability ratio test in monitoring the cumulative occurrence of adverse clinical outcomes. Retrospective analysis of three longitudinal datasets. Patients aged 65 years and over under the care of Harold Shipman between 1979 and 1997, patients under 1 year of age undergoing paediatric heart surgery in Bristol Royal Infirmary between 1984 and 1995, adult patients receiving cardiac surgery from a team of cardiac surgeons in London,UK. Annual and 30-day mortality rates. Using reasonable boundaries, the procedure could have indicated an 'alarm' in Bristol after publication of the 1991 Cardiac Surgical Register, and in 1985 or 1997 for Harold Shipman depending on the data source and the comparator. The cardiac surgeons showed no significant deviation from expected performance. The risk-adjusted sequential probability test is simple to implement, can be applied in a variety of contexts, and might have been useful to detect specific instances of past divergent performance. The use of this and related techniques deserves further attention in the context of prospectively monitoring adverse clinical outcomes.

Purpose and design The aim of this study was to establish the prevalence of known glaucoma in patients undergoing ectropion or entropion surgical repair. In this study, retrospective review of case series was performed. Participants All patients who underwent ectropion or entropion surgery in a tertiary medical center between 2007 and 2014 were included. The etiology of eyelid malpositioning was involutional or cicatricial. Methods The medical files of the study participants were reviewed for the presence and type of glaucoma, medical treatment, duration of treatment, and the amount of drops per day. These data were compared to a matched control group of 101 patients who underwent blepharoplasty for dermatochalasis in the same department during the same period. Main outcome measure In this study, the prevalence of glaucoma in individuals with ectropion or entropion was the main outcome measure. Results A total of 227 patients (57% men, mean age: 79.2 years) who underwent ectropion or entropion surgery comprised the study group and 101 patients who underwent upper blepharoplasty for dermatochalasis comprised the control group. Compared to four patients in the control group (4%, P=0.01), 30 of the study patients (13.2%) had coexisting glaucoma. Of 30 glaucomatous patients, 25 had primary open-angle glaucoma for a mean duration of 10.3 years. The glaucomatous patients were treated with an average of 2.7 antiglaucoma medications. Conclusion An increased prevalence of known glaucoma in patients undergoing ectropion or entropion repair surgery was found. This observation may indicate that the chronic usage of topical anti-glaucoma eyedrops may lead to an increased risk of developing eyelid malpositions, especially in elderly patients. PMID:27785003

Postoperative cognitive dysfunction (POCD) is a clinical syndrome characterized by cognitive declines in patients after surgery. Previous studies have suggested that surgery contributed to such impairment. It has been proven that neuroinflammation may exacerbate surgery-induced cognitive impairment in aged rats. The free radical scavenger edaravone has high blood brain barrier permeability, and was demonstrated to effectively remove free radicals from the brain and alleviate the development of POCD in patients undergoing carotid endarterectomy, suggesting its potential role in preventing POCD. For this reason, this study was designed to determine whether edaravone is protective against POCD through its inhibitory effects on inflammatory cytokines and oxidative stress. First, Sprague Dawley adult male rats were administered 3 mg/kg edaravone intraperitoneally after undergoing a unilateral nephrectomy combined with lipopolysaccharide injection. Second, behavioral parameters related to cognitive function were recorded by fear conditioning and Morris Water Maze tests. Last, superoxide dismutase activities and malondialdehyde levels were measured in the hippocampi and prefrontal cortex on postoperative days 3 and 7, and microglial (Iba1) activation, p-Akt and p-mTOR protein expression, and synaptic function (synapsin 1) were also examined 3 and 7 days after surgery. Rats that underwent surgery plus lipopolysaccharide administration showed significant impairments in spatial and working memory, accompanied by significant reductions in hippocampal-dependent and independent fear responses. All impairments were attenuated by treatment with edaravone. Moreover, an abnormal decrease in superoxide dismutase activation, abnormal increase in malondialdehyde levels, significant increase in microglial reactivity, downregulation of p-Akt and p-mTOR protein expression, and a statistically significant decrease in synapsin-1 were observed in the hippocampi and prefrontal cortices of

BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies. OBJECTIVE: To determine the motor and anatomical causes of dysphagia. METHODS: A total of 41 adults, followed at the Esophageal Atresia Clinic at Hôpital Saint-Luc (Montreal, Quebec), were approached to particpate in the present prospective study. Evaluation was completed using upper endoscopy, manometry and barium swallow for the participants who consented. The medical charts of respondents were systematically reviewed from the neonatal period to 18 years of age to assess medical and surgical history. RESULTS: All 41 patients followed at the clinic consented and were included in the study. Dysphagia was present in 73% of patients. Esophagogastroduodenoscopy was performed in 32 patients: hiatal hernia was present in 62% (n=20); esophageal diverticulum in 13% (n=4); macroscopic Barrett esophagus in 31% (n=10); and esophagitis in 19% (n=6). Histological esophagitis was present in 20% and intestinal metaplasia in 10%. There were no cases of dysplagia or adenocarcinoma. Esophageal manometry was performed on 56% of the patients (n=23). Manometry revealed hypomotility in 100% of patients and included an insufficient number of peristaltic waves in 96%, non-propagating peristalsis in 78% and low-wave amplitude in 95%. Complete aperistalsis was present in 78%. The lower esophageal sphincter was abnormal in 12 (52%) patients, with incomplete relaxation the most common anomaly. Of the 41 patients, 29 (71%) consented to a barium swallow, which was abnormal in 13 (45%). The anomalies found were short esophageal dilation in 28%, delay in esophageal emptying in 14

Regional anaesthesia comprising axillary block of the brachial plexus is a common anaesthetic technique for distal upper limb surgery. This is an update of a review first published in 2006 and updated in 2011. To compare the relative effects (benefits and harms) of three injection techniques (single, double and multiple) of axillary block of the brachial plexus for distal upper extremity surgery. We considered these effects primarily in terms of anaesthetic effectiveness; the complication rate (neurological and vascular); and pain and discomfort caused by performance of the block. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE and reference lists of trials. We contacted trial authors. The date of the last search was March 2013 (updated from March 2011). We included randomized controlled trials that compared double with single-injection techniques, multiple with single-injection techniques, or multiple with double-injection techniques for axillary block in adults undergoing surgery of the distal upper limb. We excluded trials using ultrasound-guided techniques. Independent study selection, risk of bias assessment and data extraction were performed by at least two investigators. We undertook meta-analysis. The 21 included trials involved a total of 2148 participants who received regional anaesthesia for hand, wrist, forearm or elbow surgery. Risk of bias assessment indicated that trial design and conduct were generally adequate; the most common areas of weakness were in blinding and allocation concealment.Eight trials comparing double versus single injections showed a statistically significant decrease in primary anaesthesia failure (risk ratio (RR 0.51), 95% confidence interval (CI) 0.30 to 0.85). Subgroup analysis by method of nerve location showed that the effect size was greater when neurostimulation was used rather than the transarterial technique.Eight trials comparing multiple with single

Patients undergoing major heart surgery (MHS) represent a special subpopulation at risk for nosocomial infections. Postoperative infection is the main non-cardiac complication after MHS and has been clearly related to increased morbidity, use of hospital resources and mortality. Our aim was to determine the incidence, aetiology, risk factors and outcome of ventilator-associated pneumonia (VAP) in patients who have undergone MHS in Europe. Our study was a prospective study of patients undergoing MHS in Europe who developed suspicion of VAP. During a one-month period, participating units submitted a protocol of all patients admitted to their units who had undergone MHS. Overall, 25 hospitals in eight different European countries participated in the study. The number of patients intervened for MHS was 986. Fifteen patients were excluded because of protocol violations. One or more nosocomial infections were detected in 43 (4.4%) patients. VAP was the most frequent nosocomial infection (2.1%; 13.9 episodes per 1000 days of mechanical ventilation). The microorganisms responsible for VAP in this study were: Enterobacteriaceae (45%), Pseudomonas aeruginosa (20%), methicillin-resistant Staphylococcus aureus (10%) and a range of other microorganisms. We identified the following significant independent risk factors for VAP: ascending aorta surgery (odds ratio (OR) = 6.22; 95% confidence interval (CI) = 1.69 to 22.89), number of blood units transfused (OR = 1.08 per unit transfused; 95% CI = 1.04 to 1.13) and need for re-intervention (OR = 6.65; 95% CI = 2.10 to 21.01). The median length of stay in the intensive care unit was significantly longer (P < 0.001) in patients with VAP than in patients without VAP (23 days versus 2 days). Death was significantly more frequent (P < 0.001) in patients with VAP (35% versus 2.3%). Patients undergoing aortic surgery and those with complicated post-intervention courses, requiring multiple transfusions or re-intervention, constitute a high

74 (p = 0.026). Mean Cobb angle and sagittal vertical axis decreased from 42° and 51 mm preoperatively to 16° and 27 mm postoperatively (both p < 0.001). An 88% fusion rate was confirmed on CT scan. Perioperative complications occurred in 11 of the 50 patients (22%), with delayed complications needing further surgery in 10 more patients at last followup. cMIS provides for good clinical and radiographic outcomes for moderate (30°-75°) adult idiopathic scoliosis. Patients undergoing cMIS should be carefully selected to avoid fixed, rigid deformities and a preoperative sagittal vertical axis of greater than 10 cm; surgeons should consider alternative techniques in those patients.

2018-03-09

Our objective was to examine the association of the modified frailty index (mFI) and non-home discharge in patients undergoing surgery for endometrial cancer (EMCA). Patients who underwent surgery for EMCA from 2011 to 2012 were identified from the American College of Surgeons - Nastional Surigical Quality Improvement Project (ACS-NSQIP) database. Current Procedural Terminology (CPT) codes were used to identify surgical characteristics. We excluded patients who were already living in a non-home facility. To determine frailty, we used the NSQIP frailty index. For analysis purposes, patients with an mFI score ≥0.18 were defined as frail. Patients were divided into groups based on discharge destination. Logistic regression were used to identify predictors of post-operative non-home discharge. 1216 patients were identified. 26 (2.1%) were discharged to a non-home facility. On multivariate analysis, patients who were discharged to a non-home facility were older (OR 1.09, 95% CI 1.04-1.14, p < 0.001), had a higher Body Mass Index (BMI) (OR 1.08, 95% CI 1.04-1.12, p < 0.001), were more likely to have disseminated cancer (OR 10.02, 95% CI 2.28-44.1, p = 0.002), and were frail (OR 1.95, 95% CI 1.91-5.01, p = 0.008). Undergoing minimally-invasive surgery was independently associated with discharge to home (OR 0.165, 95% CI 0.059-0.458, p = 0.001). Frailty is associated with increased risk of non-home discharge in patients undergoing surgery for EMCA. The mFI can be easily calculated using patient characteristics that are readily available pre-operatively. This information can be used for pre-op counseling and to facilitate appropriate and timely discharge planning. Copyright © 2018 Elsevier Inc. All rights reserved.

Abstract Background: Metabolic syndrome is associated with higher risk for cardiovascular disease, sleep apnea, and nonalcoholic steatohepatitis, all common conditions in patients referred for bariatric surgery, and it may predict early postoperative complications. The objective of this study was to determine the prevalence of metabolic syndrome, defined using updated National Cholesterol Education Program criteria, in adults undergoing bariatric surgery and compare the prevalence of baseline co-morbid conditions and select operative and 30-day postoperative outcomes by metabolic syndrome status. Methods: Complete metabolic syndrome data were available for 2275 of 2458 participants enrolled in the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2), an observational cohort study designed to evaluate long-term safety and efficacy of bariatric surgery in obese adults. Results: The prevalence of metabolic syndrome was 79.9%. Compared to those without metabolic syndrome, those with metabolic syndrome were significantly more likely to be men, to have a higher prevalence of diabetes and prior cardiac events, to have enlarged livers and higher median levels of liver enzymes, a history of sleep apnea, and a longer length of stay after surgery following laparoscopic Roux-en-Y gastric bypass (RYGB) and gastric sleeves but not open RYGB or laparoscopic adjustable gastric banding. Metabolic syndrome status was not significantly related to duration of surgery or rates of composite end points of intraoperative events and 30-day major adverse surgical outcomes. Conclusions: Nearly four in five participants undergoing bariatric surgery presented with metabolic syndrome. Establishing a diagnosis of metabolic syndrome in bariatric surgery patients may identify a high-risk patient profile, but does not in itself confer a higher risk for short-term adverse postsurgery outcomes.

Is non-awake surgery for supratentorial adult low-grade glioma treatment still feasible?

PubMed

Duffau, Hugues

2018-01-01

In this short review, the author performs a database search, summarizes, and discusses studies that provide information on the need to perform awake surgery to preserve quality of life/return to work of adult patients who undergo resection for a supratentorial low-grade glioma (LGG). Based upon the currently available data, the author concludes that in LGG, patients with no or only mild deficits at diagnosis, non-awake surgery can no longer be achieved. Indeed, awake craniotomy with intrasurgical electrical mapping has resulted in an increase of the extent of resection and overall survival in LGG. Furthermore, in order to resume a normal familial, social, and professional life, LGG patients with a prolonged survival expectancy have to benefit not only from language mapping when the tumor involves the left "dominant" hemisphere, but also from intraoperative mapping of sensorimotor, visuospatial, higher cognitive, and emotional functions under local anesthesia, even for gliomas situated within presumed "non-language" areas such as the right "non-dominant" hemisphere. In other words, the ultimate goal is to map the functional connectome for each patient in order to perform the resection up to the eloquent networks and then to optimize the onco-functional balance of LGG surgery. To this end, an objective neuropsychological assessment has to be achieved in a more systematic manner before and after resection. Early postoperative cognitive rehabilitation is also recommended, whenever needed.

Background Using either an angiotensin-converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB) the morning of surgery may lead to ‘functional’ postoperative acute kidney injury (AKI), measured by an abrupt increase in serum creatinine. Whether the same is true for ‘structural’ AKI, measured with new urinary biomarkers, is unknown. Methods The TRIBE-AKI study was a prospective cohort study of 1594 adults undergoing cardiac surgery at six hospitals between July 2007 and December 2010. We classified the degree of exposure to ACEi/ARB into three categories: ‘none’ (no exposure prior to surgery), ‘held’ (on chronic ACEi/ARB but held on the morning of surgery) or ‘continued’ (on chronic ACEi/ARB and taken the morning of surgery). The co-primary outcomes were ‘functional’ AKI based upon changes in pre- to postoperative serum creatinine, and ‘structural AKI’, based upon peak postoperative levels of four urinary biomarkers of kidney injury. Results Across the three levels (none, held and continued) of ACEi/ARB exposure there was a graded increase in functional AKI, as defined by AKI stage 1 or worse; (31, 34 and 42%, P for trend 0.03) and by percentage change in serum creatinine from pre- to postoperative (25, 26 and 30%, P for trend 0.03). In contrast, there were no differences in structural AKI across the strata of ACEi/ARB exposure, as assessed by four structural AKI biomarkers (neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, interleukin-18 or liver-fatty acid-binding protein). Conclusions Preoperative ACEi/ARB usage was associated with functional but not structural acute kidney injury. As AKI from ACEi/ARB in this setting is unclear, interventional studies testing different strategies of perioperative ACEi/ARB use are warranted. PMID:24081864

In anesthetized patients undergoing surgery, the role of lung-protective ventilation with lower tidal volumes is unclear. We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the effect of this ventilation strategy on postoperative outcomes. We searched electronic databases from inception through September 2014. We included RCTs that compared protective ventilation with lower tidal volumes and conventional ventilation with higher tidal volumes in anesthetized adults undergoing surgery. We pooled outcomes using a random-effects model. The primary outcome measures were lung injury and pulmonary infection. We included 19 trials (n=1348). Compared with patients in the control group, those who received lung-protective ventilation had a decreased risk of lung injury (risk ratio [RR] 0.36, 95% confidence interval [CI] 0.17 to 0.78; I2=0%) and pulmonary infection (RR 0.46, 95% CI 0.26 to 0.83; I2=8%), and higher levels of arterial partial pressure of carbon dioxide (standardized mean difference 0.47, 95% CI 0.18 to 0.75; I2=65%). No significant differences were observed between the patient groups in atelectasis, mortality, length of hospital stay, length of stay in the intensive care unit or the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen. Anesthetized patients who received ventilation with lower tidal volumes during surgery had a lower risk of lung injury and pulmonary infection than those given conventional ventilation with higher tidal volumes. Implementation of a lung-protective ventilation strategy with lower tidal volumes may lower the incidence of these outcomes. © 2015 Canadian Medical Association or its licensors.

Our objective was to describe our experience of managing a cohort of adult patients prescribed direct oral anticoagulants (DOACs) undergoing dentoalveolar procedures between November 2012 and May 2016. Prior to conducting a procedure a formal assessment was made of each patient's anticoagulation treatment. A specific plan was then formulated, balancing the risk of bleeding with the risk of thrombosis. Patients received a telephone consultation one week following treatment to assess any post-operative bleeding. Eighty-two patients underwent 111 oral surgical procedures, the majority of which were dental extractions. In the case of 35 (32%) procedures, advice was given to omit the DOAC, either before or after treatment. There was no bleeding following the majority of procedures. Persistent bleeding followed 15 (13.5%) procedures, of which 7 (6.3%) procedures required specific intervention. The majority of patients prescribed DOACs can undergo dentoalveolar procedures safely. Important considerations when planning treatment are: (i) when the patient usually takes their dose of DOAC, (ii) the time the procedure is performed and, (iii) when the DOAC is taken post-procedure. In our experience, if these factors are considered carefully, omission of DOAC doses is unlikely to be required for most patients.

Misuse and diversion of prescription opioids have been critical in facilitating the opioid epidemic. Our objective was to perform a systematic evidence-based review delineating perioperative regimens (including opioid alternatives) evaluated for endoscopic sinus surgery. PubMed/MEDLINE, Cochrane Library, and EmBase databases were evaluated for studies detailing analgesics employed after endoscopic sinus surgery. Studies were assessed for level of evidence. Bias risk was evaluated using the Cochrane Bias tool and GRADE criteria. Medication, administration, adverse effects, pain scores, and rescue analgesic consumption were evaluated. A summary of evidence detailing benefits, harm, and cost was prepared. Thirty-two studies encompassing 1812 patients were included. The GRADE criteria determined the overall evidence to be of moderate quality. Perioperative acetaminophen had few adverse events and reduced immediate need for opioid rescue after sinus surgery; studies evaluating acetaminophen demonstrate a preponderance of benefit over harm. Nonsteroidal anti-inflammatory drugs (NSAIDs) also reduce postoperative opioid consumption, although a small portion of patients undergoing sinus surgery harbor the potential for NSAID intolerance. The aggregate level of evidence for studies evaluating NSAIDs was grade A, whereas the aggregate grade of evidence for several other agents was grade B. There is evidence supporting the use of NSAIDs and gabapentin for the control of pain after endoscopic sinus surgery. Acetaminophen, α-agonists, and local anesthetics are also viable options for postoperative analgesia. Familiarity with these data is essential to facilitate the use of opioid alternatives. Further large-scale, multi-institutional, randomized trials are needed to provide conclusive recommendations for these perioperative analgesics. © 2018 ARS-AAOA, LLC.

Patients with Williams syndrome (WS) undergoing cardiac surgery are at risk for major adverse cardiac events (MACE). Prevalence and risk factors for such events have not been well described. We sought to define frequency and risk of MACE in patients with WS using a multicenter clinical registry. We identified cardiac operations performed in patients with WS using the Society of Thoracic Surgeons Congenital Heart Surgery Database (2000-2012). Operations were divided into 4 groups: isolated supravalvular aortic stenosis, complex left ventricular outflow tract (LVOT), isolated right ventricular outflow tract (RVOT), and combined LVOT/RVOT procedures. The proportion of patients with MACE (in-hospital mortality, cardiac arrest, or postoperative mechanical circulatory support) was described and the association with preoperative factors was examined. Of 447 index operations (87 centers), median (interquartile range) age and weight at surgery were 2.4 years (0.6-7.4 years) and 10.6 kg (6.5-21.5 kg), respectively. Mortality occurred in 20 patients (5%). MACE occurred in 41 patients (9%), most commonly after combined LVOT/RVOT (18 out of 87; 21%) and complex LVOT (12 out of 131; 9%) procedures, but not after isolated RVOT procedures. Odds of MACE decreased with age (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.98-0.99), weight (OR, 0.97; 95% CI, 0.93-0.99), but increased in the presence of any preoperative risk factor (OR, 2.08; 95% CI, 1.06-4.00), and in procedures involving coronary artery repair (OR, 5.37; 95% CI, 2.05-14.06). In this multicenter analysis, MACE occurred in 9% of patients with WS undergoing cardiac surgery. Demographic and operative characteristics were associated with risk. Further study is needed to elucidate mechanisms of MACE in this high-risk population. Copyright © 2015 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.

The prevalence of coronary artery disease (CAD) in valvular patients is similar to that of the general population, with the usual association with traditional risk factors. Nevertheless, the search for obstructive CAD is more aggressive in the preoperative period of patients with valvular heart disease, resulting in the indication of invasive coronary angiography (ICA) to almost all adult patients, because it is believed that coronary artery bypass surgery should be associated with valve replacement. To evaluate the prevalence of obstructive CAD and factors associated with it in adult candidates for primary heart valve surgery between 2001 and 2014 at the National Institute of Cardiology (INC) and, thus, derive and validate a predictive obstructive CAD score. Cross-sectional study evaluating 2898 patients with indication for heart surgery of any etiology. Of those, 712 patients, who had valvular heart disease and underwent ICA in the 12 months prior to surgery, were included. The P value < 0.05 was adopted as statistical significance. The prevalence of obstructive CAD was 20%. A predictive model of obstructive CAD was created from multivariate logistic regression, using the variables age, chest pain, family history of CAD, systemic arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and male gender. The model showed excellent correlation and calibration (R² = 0.98), as well as excellent accuracy (ROC of 0.848; 95%CI: 0.817-0.879) and validation (ROC of 0.877; 95%CI: 0.830 - 0.923) in different valve populations. Obstructive CAD can be estimated from clinical data of adult candidates for valve repair surgery, using a simple, accurate and validated score, easy to apply in clinical practice, which may contribute to changes in the preoperative strategy of acquired heart valve surgery in patients with a lower probability of obstructive disease.

The purpose of this study was to explore the effectiveness of the aromatherapy product QueaseEASE (QE) for decreasing postdischarge nausea (PDN) in patients undergoing outpatient abdominal surgery. Prospective exploratory study. Informed Consent was obtained preoperatively from a convenience sample of adult patients scheduled for outpatient abdominal surgery procedures. Prior to discharge, subjects were instructed in the use of QE and given instructions on how to rate their nausea on a 0-10 scale. They recorded nausea scales > 0 any time they occurred for the next 24 hours, used the QE, and recorded their nausea scales 3 minutes later. A study nurse called subjects the next day to collect the information. The sample included 70 outpatients who underwent abdominal surgery. Twenty-five participants (36%) reported experiencing PDN and their concomitant use of QE. There was a significant difference in mean age of those reporting PDN (37 years) versus those without nausea (48 years, P = .004) as well as a significant difference in mean intravenous fluid intake during hospitalization of those reporting PDN (1,310 mL) versus those without nausea (1,511 mL, P = .04). The PDN group had more female participants (72% vs 42%, P = .02), more participants that were less than 50 years of age (84% vs 53%, P = .02), and received more opioids (100% vs 76%, P = .006) than the no nausea group. The 25 PDN participants reported 47 episodes of PDN in which they used QE. For all of the 47 PDN episodes experienced, participants reported a decrease in nausea scale (0 to 10) after the use of QE; for 22 (47%) of the PDN episodes experienced, a nausea scale of 0 after using QE was reported. The mean decrease in nausea scale for all 25 participants was 4.78 (±2.12) after using QE. This study found that the aromatherapy QE was an effective treatment of PDN in select same-day abdominal surgery patients. Copyright © 2015 American Society of PeriAnesthesia Nurses.

Background. The incidence of inflammatory bowel disease (IBD) is increasing in the paediatric population. Since 2007, a single surgeon whose main practice is in the treatment of adults has performed surgery for IBD in adults and children within two dedicated multidisciplinary teams. Our aim was to assess and compare outcomes for adults and children following surgery for IBD. Methods. Analysis of a prospectively collected database was carried out to include all patients who had undergone resectional surgery for IBD between 2007 and 2012. Results. 48 adults and 30 children were included in the study. Median age for children was 14 years (range 8-16) and for adults was 33.5 years (range 17-64). Median BMI was 23 (range 18-38) and 19 (range 13-29.5) in adults and children, respectively (P < 0.001). Laparoscopic resection was performed in 27 (90%) children and 36 (75%) adults. Postoperative complication rates were comparable, 11 (23%) in adults versus 6 (20%) in children (P = 1.00). Conclusion. Resectional surgery for IBD in children has outcomes that compare favourably with the adult population, with the majority of cases being performed by a laparoscopic approach.

The perioperative management of chronic kidney disease (CKD) patients undergoing open-heart surgery is challenging. In this study, we evaluated the effects of tolvaptan in CKD patients after open-heart surgery. Between 2010 to 2015, 731 patients underwent open-heart surgery in our hospital. We consecutively selected 71 patients with stage IIIa-IV CKD and divided them into two groups. Those who received tolvaptan postoperatively were defined as the "Tolvaptan group" (n = 25) and those who did not were defined as the "Non-tolvaptan group" (n = 46). We compared the urine volume of postoperative days (POD) 1 and 2, the number of days to return to preoperative body weight (BW), and the change in the postoperative estimated glomerular filtration rate (eGFR). In the tolvaptan group, the urine volume was significantly larger (P = .04) and the duration to preoperative BW tended to be shorter. Overall, the postoperative change in the eGFR tended to be better in the tolvaptan group (P = .008). In particular, we found a significantly better trend in CKD stage IV (P = .04) patients and in the patients, whose cardiopulmonary bypass (CPB) time was longer than 120 min (P = .03). Tolvaptan can safely be used for CKD patients undergoing open-heart surgery and can provide a feasible urine volume without leading to a deterioration of their renal function.

To evaluate the effect of steroid administration on myocardial infarction (MI), stroke, renal insufficiency, death, intensive care (ICU) length of stay (LOS) and hospital LOS of patients undergoing cardiopulmonary bypass (CPB). Meta-analysis of parallel randomized controlled trials. University hospital. A search was conducted in PubMed, EMBASE, MEDLINE(R) and the Cochrane Central Register of Controlled Trials of studies on adults undergoing surgery with CPB who received steroid administration. Effect size (risk ratio or mean difference) for MI, stroke, renal insufficiency, death, ICU LOS, and hospital LOS were evaluated. 48 RCTs published between 1977 and 2012 were retained for analysis. Steroids had no effect on the MI risk ratio (RR) 0.91 (95% confidence interval [CI] 0.63, 1.32); death at 30 days RR 0.84 (0.59, 1.20); stroke RR 0.92 (0.60, 1.42) or renal insufficiency RR 0.83 (0.52, 1.32). Administration of steroids reduced ICU LOS (P = 0.00001; I(2) 87.5%) and hospital LOS (P = 0.03; I(2) 81.1%). Metaregressions showed that duration of steroid administration was correlated with the reduction in ICU LOS (P = 0.0004) and hospital LOS (P < 0.00001). Increasing the duration of steroid administration may reduce ICU and hospital LOS greater than increasing the dose. Copyright © 2014 Elsevier Inc. All rights reserved.

To understand the functional and psychosocial aspects of strabismus surgery, an evaluation based on the patient's perspective is essential. In this study, we assessed quality of life and utility in adult patients who had undergone strabismus surgery, and we modeled the cost of providing this intervention in order to calculate the cost-utility of strabismus surgery in adults. The study population comprised 226 patients with strabismus aged 18 years or older who were scheduled for ocular alignment surgery at 12 facilities of the Strabismus Surgery Study Group in Japan. Survey questionnaires consisting of the Japanese versions of the Visual Function Questionnaire-25 (VFQ-25) and 8-Item Short-Form Health Survey (SF-8) and utility assessment by a time trade-off method were administrated preoperatively and 3 months postoperatively. On the basis of the cost model and measured utility data, the gains in quality-adjusted life years (QALYs) and $/QALY were estimated. Postoperatively, the subscale scores of the VFQ-25 and the physical and mental component summary scores of the SF-8 showed a statistically significant improvement. A significant improvement of utility was also noted: 0.82 ± 0.28 postoperatively versus 0.76 ± 0.31 preoperatively. On the basis of the life expectancy of these patients and the cost model, the surgery resulted in a mean value gain of 0.99 QALYs and a cost-utility for strabismus surgery of 1,303 $/QALY. By using standard tools to assess vision-associated and general health status, we confirmed the psychosocial benefits of corrective surgery for adults with strabismus. Our study concurrently demonstrated that strabismus surgery in adults is very cost-effective.

Cardiovascular magnetic resonance (CMR) is a versatile non-invasive imaging modality that serves a broad spectrum of indications in clinical cardiology and has proven evidence. Most of the numerous applications are appropriate in patients with previous cardiovascular surgery in the same manner as in non-surgical subjects. However, some specifics have to be considered. This review article is intended to provide information about the application of CMR in adults with previous cardiovascular surgery. In particular, the two main scenarios, i.e. following coronary artery bypass surgery and following heart valve surgery, are highlighted. Furthermore, several pictorial descriptions of other potential indications for CMR after cardiovascular surgery are given.

Patients undergoing minimally invasive cardiac surgery have the potential for significant pain from the thoracotomy site. We report the successful use of pectoral nerve block types I and II (Pecs I and II) as rescue analgesia in a patient undergoing minimally invasive mitral valve repair. In this case, a 78-year-old man, with no history of chronic pain, underwent mitral valve repair via right anterior thoracotomy for severe mitral regurgitation. After extubation, he complained of 10/10 pain at the incision site that was minimally responsive to intravenous opioids. He required supplemental oxygen because of poor pulmonary mechanics, with shallow breathing and splinting due to pain, and subsequent intensive care unit readmission. Ultrasound-guided Pecs I and II blocks were performed on the right side with 30 mL of 0.2% ropivacaine with 1:400,000 epinephrine. The blocks resulted in near-complete chest wall analgesia and improved pulmonary mechanics for approximately 24 hours. After the single-injection blocks regressed, a second set of blocks was performed with 266 mg of liposomal bupivacaine mixed with bupivacaine. This second set of blocks provided extended analgesia for an additional 48 hours. The patient was weaned rapidly from supplemental oxygen after the blocks because of improved analgesia. Pectoral nerve blocks have been described in the setting of breast surgery to provide chest wall analgesia. We report the first successful use of Pecs blocks to provide effective chest wall analgesia for a patient undergoing minimally invasive cardiac surgery with thoracotomy. We believe that these blocks may provide an important nonopioid option for the management of pain during recovery from minimally invasive cardiac surgery.

Background Despite demonstrated efficacy of ϵ-aminocaproic acid (EACA) in reducing blood loss in adolescents undergoing spinal fusion, there are no population-specific pharmacokinetic data to guide dosing. The aim of this study was to determine the pharmacokinetics of EACA in adolescents undergoing spinal fusion surgery and make dosing recommendations. Methods Twenty children ages 12–17 years were enrolled, with 10 children in each of two groups based on diagnosis (idiopathic scoliosis or non-idiopathic scoliosis). Previously reported data from infants undergoing craniofacial surgery were included in the model to enable dosing recommendations over a wide range of weights, ages, and diagnoses. A population non-linear mixed effects modelling approach was used to characterize EACA pharmacokinetics. Results Population pharmacokinetic parameters were estimated using a two-compartment disposition model with allometrically scaled weight and an age effect on clearance. Pharmacokinetic parameters for the typical patient were a plasma clearance of 153 ml min−1 70 kg−1 (6.32 ml min−1 kg−0.75), intercompartmental clearance of 200 ml min−1 70 kg−1 (8.26 ml min−1 kg−0.75), central volume of distribution of 8.78 litre 70 kg−1 (0.13 litre kg−1), and peripheral volume of distribution of 15.8 litre 70 kg−1 (0.23 litre kg−1). Scoliosis aetiology did not have a clinically significant effect on drug pharmacokinetics. Conclusions The following dosing schemes are recommended according to patient weight: weight <25 kg, 100 mg kg−1 loading dose and 40 mg kg−1 h−1 infusion; weight ≤25 kg–<50 kg, 100 mg kg−1 loading dose and 35 mg kg−1 h−1 infusion; and weight ≥50 kg, 100 mg kg−1 loading dose and 30 mg kg−1 h−1 infusion. An efficacy trial employing this dosing strategy is warranted. Clinical trial registration NCT01408823. PMID:25586726

Urinary cultures revealed infection in 10 patients. Half of them had been shaved, suggesting that this practice does not affect the incidence of urinary infections.

Frailty and falls among adult patients undergoing chronic hemodialysis: a prospective cohort study

PubMed Central

2013-01-01

Background Patients undergoing hemodialysis are at high risk of falls, with subsequent complications including fractures, loss of independence, hospitalization, and institutionalization. Factors associated with falls are poorly understood in this population. We hypothesized that insights derived from studies of the elderly might apply to adults of all ages undergoing hemodialysis; we focused on frailty, a phenotype of physiological decline strongly associated with falls in the elderly. Methods In this prospective, longitudinal study of 95 patients undergoing hemodialysis (1/2009-3/2010), the association of frailty with future falls was explored using adjusted Poisson regression. Frailty was classified using the criteria established by Fried et al., as a combination of five components: shrinking, weakness, exhaustion, low activity, and slowed walking speed. Results Over a median 6.7-month period of longitudinal follow-up, 28.3% of study participants (25.9% of those under 65, 29.3% of those 65 and older) experienced a fall. After adjusting for age, sex, race, comorbidity, disability, number of medications, marital status, and education, frailty independently predicted a 3.09-fold (95% CI: 1.38-6.90, P=0.006) higher number of falls. This relationship between frailty and falls did not differ for younger and older adults (P=0.57). Conclusions Frailty, a validated construct in the elderly, was a strong and independent predictor of falls in adults undergoing hemodialysis, regardless of age. Our results may aid in identifying frail hemodialysis patients who could be targeted for multidimensional fall prevention strategies. PMID:24131569

To describe the clinical course of paediatric patients undergoing surgery for congenital heart disease in UMAE of Yucatan. Descriptive review was performed on the records of paediatric patients undergoing surgery for congenital heart disease from 1 November 2011 to 30 November 2013. The most frequent heart diseases were persistent ductus arteriosus (37.6%) and transposition of the great vessels. The median intensive care stay was 3 days. Mortality was 11.76%, with septic shock (44.4%) in most cases. The most frequent complications were sepsis (5.9%), low cardiac output syndrome (4.7%), cardiac arrest, and AV block and ventricular tachycardia (2.4% each). There was a moderate positive correlation between surgical complications and survival or death. The number of surgical patients is lower compared to reference centres for cardiovascular surgery. There is a marked tendency to perform corrective and palliative surgeries in specific disease in patients with added risk or 'bad' cardiac anatomy that prevent full correction at the first attempt. Prospective epidemiological and clinical studies should be conducted to understand the behaviour of congenital heart diseases treated in the region.

Patients with glutaric aciduria type I are at risk for acute striatal injury precipitated by catabolic stress. Here, we report the successful interdisciplinary anesthetic and perioperative management of a child with glutaric aciduria type I undergoing cardiac surgery with extracorporeal circulation. Given the central focus on prevention of acute striatal injury, our anesthetic strategy emphasized avoiding a high protein load, high-dose inotropics, especially epinephrine (associated with impaired glucose utilization), deliberate hyperventilation, and other interventions associated with systemic inflammatory response.

Acute confusional states in patients undergoing hip surgery. a prospective observation study.

Duppils, G S; Wikblad, K

2000-01-01

There is general agreement that acute confusional state (ACS) is common among elderly patients admitted to hospital, although exact figures are difficult to obtain. The objective of the current study was to investigate the onset of ACS during hospital stay and to isolate possible predisposing, facilitating and precipitating factors associated with the onset of ACS. Non-confused patients, greater than or = 65 years of age, undergoing orthopedic hip surgery, were consecutively included in the study (n = 225). Of these, 149 patients were operated on because of acute hip fracture and 76 underwent elective hip-replacement surgery. ACS was diagnosed by the DSM-IV criteria for delirium. Structured observations of ACS onset were performed every 2nd to every 4th hour during the patients' entire hospital stay. A protocol was used to document the observations on sleep, activities, well being and behavior. The Mini-Mental State Examination was used to measure cognitive functioning. Of 225 patients 20% were diagnosed with ACS. The incidence of ACS was 24.3% in the group of hip-fractured patients and 11.7% in the hip-replacement surgery patients. The onset of ACS was postoperative (mean 24 +/- 21 h after surgery) in all but 8 patients. The duration of ACS among recovered patients was generally less than 48 h (mean 42 +/- 43 h). Predisposing factors were older age, cognitive impairment and pre-existing cerebrovascular or other brain diseases. Facilitating factors related to ACS were associated with communication and social isolation, e.g. impaired hearing and sight, reticence and passivity. One precipitating factor, besides surgery, may be the use of psychopharmacological drugs. The incidence of ACS was 20% among hip surgery patients. Older age and social isolation were factors associated with ACS. Increased attention and interaction with older patients could be of value in avoiding ACS during hospitalization.

Nutritional status has major impacts on the outcome of surgery, in particular in patients with cancer. The aim of this review was to assess the merit of oral pre-operative nutritional support as a part of prehabilitation in patients undergoing surgery for colorectal cancer. A systematic literature search and meta-analysis was performed according to the Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA) recommendations in order to review all trials investigating the effect of oral pre-operative nutritional support in patients undergoing colorectal surgery. The primary outcome was overall complication rate. Secondary outcomes were incision infection rate, anastomotic leakage rate, and length of hospital stay. Five randomized controlled trials and one controlled trial were included. The studies contained a total of 583 patients with an average age of 63 y (range 23-88 y), of whom 87% had colorectal cancer. Malnourishment rates ranged from 8%-68%. All investigators provided an oral protein supplement. Overall patient compliance rates ranged from 72%-100%. There was no significant reduction in the overall complication rate in the interventional groups (odds ratio 0.82; 95% confidence interval 0.52 - 1.25). Current studies are too heterogeneous to conclude that pre-operative oral nutritional support could enhance the condition of patients undergoing colorectal surgery. Patients at risk have a relatively lean body mass deficit (sarcopenia) rather than an absolute malnourished status. Compliance is an important element of prehabilitation. Targeting patients at risk, combining protein supplements with strength training, and defining standardized patient-related outcomes will be essential to obtain satisfactory results.

There is no reliable method to monitor renal blood flow intraoperatively. In this study, we evaluated the feasibility and reproducibility of left renal blood flow measurements using transesophageal echocardiography during cardiac surgery. In this prospective noninterventional study, left renal blood flow was measured with transesophageal echocardiography during three time points (pre-, intra-, and postcardiopulmonary bypass) in 60 patients undergoing cardiac surgery. Sonograms from 6 subjects were interpreted by 2 blinded independent assessors at the time of acquisition and 6 mo later. Interobserver and intraobserver reproducibility were quantified by calculating variability and intraclass correlation coefficients. Patients with Doppler angles of >30 degrees (20 of 60 subjects) were eliminated from renal blood flow measurements. Left renal blood flow was successfully measured and analyzed in 36 of 60 (60%) subjects. Both interobserver and intraobserver variability were <10%. Interobserver and intraobserver reproducibility in left renal blood flow measurements were good to excellent (intraclass correlation coefficients 0.604-0.999). Left renal arterial luminal diameter for the pre, intra, and postcardiopulmonary bypass phases, ranged from 3.8 to 4.1 mm, renal arterial velocity from 25 to 35 cm/s, and left renal blood flow from 192 to 299 mL/min. In patients undergoing cardiac surgery, it was feasible in 60% of the subjects to measure left renal blood flow using intraoperative transesophageal echocardiography. The interobserver and intraobserver reproducibility of renal blood flow measurements was good to excellent.

Recent data reaffirm decreased health-related quality of life (HRQL) in obese adults and children. Health-related quality of life is markedly improved after bariatric surgery in adults. Little HRQL data are available in adolescents undergoing bariatric surgery. Sixteen patients (14-20 years old) underwent gastric bypass. Thirteen patients completed a general HRQL measure (Short Form 36 [SF-36]) before surgery. Of these, 9 completed the SF-36 again at various follow-up times, as well as a measure of weight-related quality of life (Impact of Weight on Quality of Life-Lite). Three patients completed postsurgical forms only. Data were analyzed using t test and analysis of variance. Results are reported as mean +/- SD. Mean age and body mass index at operation were 18.5 +/- 1.7 years and 54 +/- 7.6 kg/m(2). Postoperatively, patients lost an average of 66% +/- 29% excess weight over a mean follow-up of 17 +/- 12 (range, 1-39) months. Mean preoperative SF-36 physical component score was 34.7 +/- 10 and mental component score was 40.6 +/- 13.5 (adult population mean = 50.0 +/- 10 for each). At last follow-up, mean physical component score had increased to 55.5 +/- 5, and mental component score, to 55.2 +/- 8.6 (P < .0001). Adolescent Impact of Weight on Quality of Life-Lite scores after surgery did not differ from means for normal weight adults (93% +/- 7% vs 96% +/- 7%, P = .15). Health-related quality of life in adolescents and young adults undergoing bariatric surgery improves dramatically in early follow-up. Long-term data are needed to definitively study this surgical therapy for obesity in adolescents.

A relatively new method of electrocautery, the radiofrequency bipolar hemostatic sealer (RBHS), uses saline-cooled delivery of energy, which seals blood vessels rather than burning them. We assessed the benefits of RBHS as a blood conservation strategy in adult patients undergoing multilevel spinal fusion surgery. In a retrospective cohort study, we compared blood utilization in 36 patients undergoing multilevel spinal fusion surgery with RBHS (Aquamantys, Medtronic, Minneapolis, MN, USA) to that of a historical control group (n = 38) matched for variables related to blood loss. Transfusion-related costs were calculated by two methods. Patient characteristics in the two groups were similar. Intraoperatively, blood loss was 55% less in the RBHS group than in the control group (810 ± 530 vs. 1,800 ± 1,600 mL; p = 0.002), and over the entire hospital stay, red cell utilization was 51% less (2.4 ± 3.4 vs. 4.9 ± 4.5 units/patient; p = 0.01) and plasma use was 56% less (1.1 ± 2.4 vs. 2.5 ± 3.4 units/patient; p = 0.03) in the RBHS group. Platelet use was 0.1 ± 0.5 and 0.3 ± 0.6 units/patient in the RBHS and control groups, respectively (p = 0.07). The perioperative decrease in hemoglobin was less in the RBHS group than in the control group (-2.0 ± 2.2 vs. -3.2 ± 2.1 g/dL; p = 0.04), and hemoglobin at discharge was higher in the RBHS group (10.5 ± 1.4 vs. 9.7 ± 0.9 g/dL; p = 0.01). The estimated transfusion-related cost savings were $745/case by acquisition cost and approximately 3- to 5-fold this amount by activity-based cost. The use of RBHS in patients undergoing multilevel spine fusion surgery can conserve blood, promote higher hemoglobin levels, and reduce transfusion-related costs.

The obesity prevalence is increasing in surgical population. As the number of obese surgical patients increases, so does the demand for mechanical ventilation. Nevertheless, ventilatory strategies in this population are challenging, since obesity results in pathophysiological changes in respiratory function. Areas covered: We reviewed the impact of obesity on respiratory system and the effects of controlled invasive mechanical ventilation strategies in obese patients undergoing surgery. To date, there is no consensus regarding the optimal invasive mechanical ventilation strategy for obese surgical patients, and no evidence that possible intraoperative beneficial effects on oxygenation and mechanics translate into better postoperative pulmonary function or improved outcomes. Expert commentary: Before determining the ideal intraoperative ventilation strategy, it is important to analyze the pathophysiology and comorbidities of each obese patient. Protective ventilation with low tidal volume, driving pressure, energy, and mechanical power should be employed during surgery; however, further studies are required to clarify the most effective ventilation strategies, such as the optimal positive end-expiratory pressure and whether recruitment maneuvers minimize lung injury. In this context, an ongoing trial of intraoperative ventilation in obese patients (PROBESE) should help determine the mechanical ventilation strategy that best improves clinical outcome in patients with body mass index≥35kg/m 2 .

Thoracic spinal anesthesia is safe for patients undergoing abdominal cancer surgery.

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can't tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than

Noncardiac surgery performed after coronary stent implantation is associated with an increased risk of stent thrombosis, myocardial infarction, and death. The influence of stent type and period of risk still have to be defined. We linked the Scottish Coronary Revascularisation Register with hospital admission data to undertake a Scotland-wide retrospective cohort study examining cardiac outcomes in all patients who received drug-eluting or bare-metal stents between April 2003 and March 2007 and subsequently underwent noncardiac surgery. Of 1953 patients, 570 (29%) were treated with at least 1 drug-eluting stent and 1383 (71%) with bare-metal stents only. There were no differences between drug-eluting and bare-metal stents in the primary end point of in-hospital mortality or ischemic cardiac events (14.6% versus 13.3%; P=0.3) or the secondary end points of in-hospital mortality (0.7% versus 0.6%; P=0.8) and acute myocardial infarction (1.2% versus 0.7%; P=0.3). Perioperative death and ischemic cardiac events occurred more frequently when surgery was performed within 42 days of stent implantation (42.4% versus 12.8% beyond 42 days; P<0.001), especially in patients revascularized after an acute coronary syndrome (65% versus 32%; P=0.037). There were no temporal differences in outcomes between the drug-eluting and bare-metal stent groups. Patients undergoing noncardiac surgery after recent coronary stent implantation are at increased risk of perioperative myocardial ischemia, myocardial infarction, and death, particularly after an acute coronary syndrome. For at least 2 years after percutaneous coronary intervention, cardiac outcomes after noncardiac surgery are similar for both drug-eluting and bare-metal stents.

To design and validate an instrument to assess the relevance of educational programs for parents of children with congenital heart disease (CHD) undergoing cardiac surgery. In October 2011, an instrument was designed based on Kaufman's model and on the bibliography, and a survey was developed in the form of a checklist with 32 close-ended questions about received education and desired education, categorized into 5 items: educator, time, place, means, and content. The survey was reviewed by 4 academic professionals and 9 experts in the care of children with CHD, and the checklist was extended to include 42 close-ended questions and 5 open questions. The instrument was administered on the day before discharge to the parents of children with CHD undergoing cardiac surgery at the Department of Pediatrics between February and August 2013. The survey was self-administered by the first participants and administered by the investigator among the remaining participants. Fifty-five children met inclusion criteria; a total of 60 parents took part in the study. Agreement was observed between received education and desired education, which was statistically significant only in terms of education provided by a cardiologist (p= 0.000, K= 0.659) and in the hall (p= 0.000, K= 0.655). Statistically significant differences were observed between the 19 self-administered surveys and the 41 surveys administered by the investigator. Among the latter, a greater level of completion was observed for all items. A validated instrument was developed to assess the relevance of educational programs for parents of children with CHD undergoing cardiac surgery. This survey should be administered by a health care provider for a better understanding of information. Sociedad Argentina de Pediatría

Background Current methods to predict patients' peri-operative morbidity utilize complex algorithms with multiple clinical variables focusing primarily on organ-specific compromise. The aim of the present study is to determine the value of a timed stair climb (SC) in predicting peri-operative complications for patients undergoing abdominal surgery. Study Design From March 2014 to July 2015, 362 patients attempted SC while being timed prior to undergoing elective abdominal surgery. Vital signs were measured before and after SC. Ninety day post-operative complications were assessed by the Accordion Severity Grading System. The prognostic value of SC was compared to the ACS NSQIP risk calculator. Results A total of 264 (97.4%) patients were able to complete SC. SC time directly correlated to changes in both mean arterial pressure and heart rate as an indicator of stress. An Accordion grade 2 or higher complication occurred in 84 (25%) patients. There were 8 mortalities (2.4%). Patients with slower SC times had an increased complication rate (P<0.0001). In multivariable analysis SC time was the single strongest predictor of complications (OR=1.029, P<0.0001), and no other clinical co-morbidity reached statistical significance. Receiver operative characteristic curves predicting post-operative morbidity by SC time was superior to that of the ACS risk calculator (AUC 0.81 vs. 0.62, P<0.0001). Additionally slower patients had a greater deviation from predicted length of hospital stay (P=0.034) Conclusions SC provides measurable stress, accurately predicts post-operative complications, and is easy to administer in patients undergoing abdominal surgery. Larger patient populations with a diverse group of operations will be needed to further validate the use of SC in risk prediction models. PMID:26920993

Background: The thought of having a surgery can be stressful for everyone. Providing the necessary information to the patient can help both the patient and the treatment team. This study was conducted to compare the effectiveness of face-to-face verbal training and educational pamphlets on the readiness of patients for undergoing non-emergency surgeries. Materials and Methods: The study was a before–after randomized clinical trial. 90 patients scheduled to undergo non-emergency surgery who referred to Shahrekord Ayatollah Kashani Hospital in 2013 were distributed randomly and gradually into two experimental groups (group of face-to-face verbal training and group of educational pamphlet) and one control group. Dependent variable of the study was pre-surgery readiness. Data analysis was carried out by using SPSS statistical software. Statistical analysis were analysis of variance (ANOVA) and correlation test. Results: Results showed that the mean scores of pre-surgery readiness in both interventional groups were significantly higher than that in the control group after the intervention (P < 0.05). However, there was no significant difference between the two experimental groups (P > 0.05). Conclusions: Each of the methods of face-to-face verbal education and using the pamphlet could be equally effective in improving the readiness of the patients undergoing surgery. Therefore, in environments where the health care providers are facing with the pressure of work and lack of sufficient time for face-to-face verbal training, suitable educational pamphlets can be used to provide the necessary information to patients and prepare them for surgery.

Women undergoing minimally invasive robotic-assisted surgery for a gynecologic malignancy have many questions and concerns related to the cancer diagnosis and surgery. The provision of information enhances coping with such illness-related challenges. A lack of print materials for these patients prompted the creation of a written teaching tool to improve informational support. A booklet was developed using guidelines for the design of effective patient education materials, including an iterative process of collaboration with healthcare providers and women who had undergone robotic-assisted surgery, as well as attention to readability. The 52-page booklet covers the trajectory of the woman's experience and includes the physical, psychosocial, and sexual aspects of recovery.

The primary objective of the study was to identify perioperative factors associated with successful immediate extubation in the operating room after adult cardiac surgery. The secondary objective was to derive a simplified predictive scoring system to guide clinicians in operating room extubation. All 1518 patients in this retrospective cohort study underwent standardized fast-track cardiac anesthetic protocol during adult cardiac surgery. Perioperative variables between patients who had successful extubation in the operating room versus in the intensive care unit were retrospectively analyzed using both univariate and multivariable logistic regression analyses. A predictive score of successful operating room extubation was constructed from the multivariable results of 800 patients (derivation set), and the scoring system was further tested using a validation set of 398 patients. Younger age, lower body mass index, higher preoperative serum albumin, absence of chronic lung disease and diabetes, less-invasive surgical approach, isolated coronary bypass surgery, elective surgery, and lower doses of intraoperative intravenous fentanyl were independently associated with higher probability of operating room extubation. The extubation prediction score created in a derivation set of patients performed well in the validation set. Patient scores less than 0 had a minimal probability of successful operating room extubation. Operating room extubation was highly predicted with scores of 5 or greater. Perioperative factors that are independently associated with successful operating room extubation after adult cardiac operations were identified, and an operating room extubation prediction scoring system was validated. This scoring system may be used to guide safe operating room extubation after cardiac operations. Copyright © 2017 The American Association for Thoracic Surgery. Published by Elsevier Inc.

Bariatric surgery is associated with sustained weight loss and improved physical health status for severely obese individuals. Mental health conditions may be common among patients seeking bariatric surgery; however, the prevalence of these conditions and whether they are associated with postoperative outcomes remains unknown. To determine the prevalence of mental health conditions among bariatric surgery candidates and recipients, to evaluate the association between preoperative mental health conditions and health outcomes following bariatric surgery, and to evaluate the association between surgery and the clinical course of mental health conditions. We searched PubMed, MEDLINE on OVID, and PsycINFO for studies published between January 1988 and November 2015. Study quality was assessed using an adapted tool for risk of bias; quality of evidence was rated based on GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. We identified 68 publications meeting inclusion criteria: 59 reporting the prevalence of preoperative mental health conditions (65,363 patients) and 27 reporting associations between preoperative mental health conditions and postoperative outcomes (50,182 patients). Among patients seeking and undergoing bariatric surgery, the most common mental health conditions, based on random-effects estimates of prevalence, were depression (19% [95% CI, 14%-25%]) and binge eating disorder (17% [95% CI, 13%-21%]). There was conflicting evidence regarding the association between preoperative mental health conditions and postoperative weight loss. Neither depression nor binge eating disorder was consistently associated with differences in weight outcomes. Bariatric surgery was, however, consistently associated with postoperative decreases in the prevalence of depression (7 studies; 8%-74% decrease) and the severity of depressive symptoms (6 studies; 40%-70% decrease). Mental health conditions are common among bariatric surgery patients

Music and surgery. To determine the effect of live classical piano music on vital signs of patients undergoing ophthalmic surgery. Retrospective case series. 203 patients who underwent various ophthalmologic procedures in a period during which a piano was present in the operating room of St. Francis Medical Center. [Note: St. Francis Medical Center has recently been renamed Hawaii Medical Center East.] Demographic data, surgical procedures, and the vital signs of 203 patients who underwent ophthalmic procedures were obtained from patient records. Blood pressure, heart rate, and respiratory rate measured in the preoperative holding area were compared with the same parameters taken in the operating room, with and without exposure to live piano music. A paired t-test was used for statistical analysis. Mean arterial pressure, heart rate, and respiratory rate. 115 patients who were exposed to live piano music showed a statistically significant decrease in mean arterial blood pressure, heart rate, and respiratory rate in the operating room compared with their vital signs measured in the preoperative holding area (P < .0001). The control group of 88 patients not exposed to live piano music showed a statistically significant increase in mean arterial blood pressure (P < .0002) and heart rate and respiratory rate (P < .0001). Live classical piano music lowered the blood pressure, heart rate, and respiratory rate in patients undergoing ophthalmic surgery.

Patients with endocrine diseases such as acromegaly and Cushing's disease have a high prevalence of obstructive sleep apnea (OSA). There is controversy regarding the use of continuous positive airway pressure (CPAP) following transsphenoidal surgery. The aim of this study was to compare the perioperative management and complications, in patients with or without OSA undergoing transsphenoidal surgery. After Research Ethics Board approval, we retrospectively reviewed the charts of all patients who underwent transsphenoidal surgery in our institution from 2006 to 2011. Information collected included patients' demographics, pathology of lesion, history of OSA, anesthetic and perioperative management and incidence of perioperative complications. Patients with sleep study proven OSA were compared with a control group, matched for age, sex and pathology of patients without OSA. Statistical analysis was performed using t-test and Chi-square test and the P < 0.05 was considered to be significant. Out of a total 469 patients undergoing transsphenoidal surgery, 105 patients were found to be at risk for OSA by a positive STOP-BANG scoring assessment. Preoperative sleep study testing was positive for OSA in 38 patients. Post-operative hypoxemia (SpO2 < 90) occurred in 10 (26%) patients with OSA and was treated with high-flow oxygen through face mask (n = 7) and by CPAP mask (n = 3). In the OSA-negative group, 2 patients had hypoxemia and were treated with low-flow oxygen using face mask. There were no differences between the groups with respect to post-operative opioid use, destination, hospital stay or other complications. Post-operative hypoxemia in patients with OSA following transsphenoidal surgery can be treated in most but not all patients with high flow oxygen using the face mask. We were able to safely use CPAP in a very small number of patients but caution is needed to prevent complications. Further prospective studies are needed to determine the safe use of CPAP in

Postoperative pulmonary impairments are significant complications after cardiac surgery. Decreased respiratory muscle strength could be one reason for impaired lung function in the postoperative period. The primary aim of this study was to describe respiratory muscle strength before and two months after cardiac surgery. A secondary aim was to describe possible associations between respiratory muscle strength and lung function. In this prospective observational study 36 adult cardiac surgery patients (67 ± 10 years) were studied. Respiratory muscle strength and lung function were measured before and two months after surgery. Pre- and postoperative respiratory muscle strength was in accordance with predicted values; MIP was 78 ± 24 cmH2O preoperatively and 73 ± 22 cmH2O at two months follow-up (p = 0.19). MEP was 122 ± 33 cmH2O preoperatively and 115 ± 38 cmH2O at two months follow-up (p = 0.18). Preoperative lung function was in accordance with predicted values, but was significantly decreased postoperatively. At two-months follow-up there was a moderate correlation between MIP and FEV1 (r = 0.43, p = 0.009). Respiratory muscle strength was not impaired, either before or two months after cardiac surgery. The reason for postoperative lung function alteration is not yet known. Interventions aimed at restore an optimal postoperative lung function should focus on other interventions then respiratory muscle strength training.

We conducted the present study to determine the usefulness of routinely inserting a pediatric airway exchange catheter (PAEC) before tracheal extubation of adult patients who had undergone maxillofacial or major neck surgery and have risk factors for difficult reintubation. A prospective, observational and clinical study was performed in the 25-bed general intensive care unit of a university hospital. Thirty-six adult patients who underwent maxillofacial or major neck surgery and had risk factors for difficult reintubation were extubated after insertion of the PAEC. Four of 36 (11.1%) patients required emergency reintubation after 2, 4, 6 and 18 hours after tracheal extubation, respectively. Reintubation of these patients, which was thought to be nearly impossible by direct laryngoscopy, was easily achieved over the PAEC. The PAEC can be a life-saving device during reintubation of patients with risk factors for difficult reintubation such as laryngeo-pharyngeal oedema due to surgical manipulation or airway obstruction resulting from haematoma and anatomic changes. We therefore suggest the routine use of the PAEC in patients undergoing major maxillofacial or major neck surgery.

Objective: To compare the diagnostic accuracy of multi-slice computed tomography (MSCT) angiography with conventional angiography in patients undergoing major noncoronary cardiac surgeries. Materials and Methods: We studied fifty major noncoronary cardiac surgery patients scheduled for invasive coronary angiography, 29 (58%) female and 21 (42%) male. Inclusion criteria of the study were age of the patients ≥40 years, having low or intermediate probability of coronary artery disease (CAD), left ventricular ejection fraction (LVEF) >35%, and patient giving informed consent for undergoing MSCT and conventional coronary angiography. The patients with LVEF <35%, high pretest probability of CAD, and hemodynamically unstable were excluded from the study. Results: The diagnostic accuracy of CT coronary angiography was evaluated regarding true positive, true negative values. The overall sensitivity and specificity of CT angiography technique was 100% (95% confidence interval [CI]: 39.76%–100%) and 91.30% (95% CI: 79.21%–97.58%). The positive (50%; 95% CI: 15.70%–84.30%) and negative predictive values (100%; 95% CI: 91.59%–100%) of CT angiography were also fairly high in these patients. Conclusion: Our study suggests that this non-invasive technique may improve perioperative risk stratification in patients undegoing non-cardiac surgery. PMID:27867455

Introduction: Methylprednisolone (MP) is frequently preoperatively administered in children undergoing open heart surgery. The aim of this medication is to inhibit overshooting immune responses. Earlier studies demonstrated cellular and humoral immunological changes in pediatric patients undergoing heart surgeries with and without MP administration. Here in a retrospective study we investigated the modulation of the cellular immune response by MP. The aim was to identify suitable parameters characterizing MP effects by cluster analysis. Methods: Blood samples were analysed from two aged matched groups with surgical correction of septum defects. Group without MP treatment consisted of 10 patients; MP was administered on 21 patients (median dose: 11mg/kg) before cardiopulmonary bypass (CPB). EDTA anticoagulated blood was obtained 24 h preoperatively, after anesthesia, at CPB begin and end (CPB2), 4h, 24h, 48h after surgery, at discharge and at out-patient followup (8.2; 3.3-12.2 month after surgery; median and IQR). Flow cytometry showed the biggest MP relevant changes at CPB2 and 4h postoperatively. They were used for clustering analysis. Classification was made by discriminant analysis and cluster analysis by means of Genes@work software. Results & conclusion: 146 parameters were obtained from analysis. Cross-validation revealed several parameters being able to discriminate between MP groups and to identify immune modulation. MP administration resulted in a delayed activation of monocytes, increased ratio of neutrophils, reduced T-lymphocytes counts. Cluster analysis demonstrated that classification of patients is possible based on the identified cytomics parameters. Further investigation of these parameters might help to understand the MP effects in pediatric open heart surgery.

To determine the frequency of postoperative vomiting in dogs undergoing routine orthopedic surgery that were treated with hydromorphone and whether that frequency would vary on the basis of administration route. Noncontrolled clinical trial. Animals-58 client-owned dogs with cranial cruciate ligament deficiency. Before surgery, all dogs received hydromorphone (0.1 mg/kg [0.045 mg/lb], IM or IV) and 41 dogs also received acepromazine. Anesthesia was induced with diazepam and propofol and maintained with isoflurane in oxygen. Dogs subsequently underwent surgical stabilization of the stifle joint. After surgery, dogs were randomly assigned to receive hydromorphone (0.1 mg/kg) via one of the following routes: IM, IV quickly (for 1 to 2 seconds), or IV slowly (for approx 1 minute). Dogs were monitored for vomiting. A median of 4 doses of hydromorphone/dog was administered after surgery. One dog was observed to regurgitate once prior to postoperative IM administration of hydromorphone; no dogs vomited at any point during the study period, regardless of the method of hydromorphone administration. The method of hydromorphone administration had no apparent effect on the likelihood of dogs vomiting. Because no dogs vomited, a particular administration method cannot be recommended. However, findings suggested that hydromorphone can be administered to dogs following orthopedic surgery without a clinically important risk of vomiting or regurgitation.

Intraoperative hypothermia is common in patients undergoing general anesthesia during arthroscopic hip surgery. In the present study, we assessed the effect of heating and humidifying the airway with a heated wire humidification circuit (HHC) to attenuate the decrease of core temperature and prevent hypothermia in patients undergoing arthroscopic hip surgery under general anesthesia. Fifty-six patients scheduled for arthroscopic hip surgery were randomly assigned to either a control group using a breathing circuit connected with a heat and moisture exchanger (HME) (n = 28) or an HHC group using a heated wire humidification circuit (n = 28). The decrease in core temperature was measured from anesthetic induction and every 15 minutes thereafter using an esophageal stethoscope. Decrease in core temperature from anesthetic induction to 120 minutes after induction was lower in the HHC group (-0.60 ± 0.27℃) compared to the control group (-0.86 ± 0.29℃) (P = 0.001). However, there was no statistically significant difference in the incidence of intraoperative hypothermia or the incidence of shivering in the postanesthetic care unit. The use of HHC may be considered as a method to attenuate intraoperative decrease in core temperature during arthroscopic hip surgery performed under general anesthesia and exceeding 2 hours in duration.

There is a growing understanding of the prevalence and impact of affective disorders on perception of health status in patients undergoing elective spine surgery. However, the role of these disorders in early readmission is unclear. The aim of this study is to investigate the influence of psychiatric comorbidities on 30-day all-cause readmissions after elective spine surgery. The medical records of 400 patients undergoing elective spine surgery at a major academic medical center were reviewed, of which 107 patients had comprehensive 1- and 2-year patient-reported outcomes data. We identified all unplanned readmissions within 30 days of discharge. The prevalence of affective disorders, such as depression and anxiety, were also assessed. All-cause readmissions within 30 days of discharge was the primary outcome variable. Baseline characteristics were similar between groups. Approximately 6% of patients in this study were readmitted within 30 days of discharge. The rate of readmission was 3-fold more for individuals with a psychiatric comorbidity compared with those without a psychiatric comorbidity (10.34% vs. 3.84%, P = 0.03). In a univariate analysis, race, body mass index, gender, patient age, smoking, diabetes, and fusion levels were associated with increased 30-day readmission rates. However, in a multivariate logistic regression model, depression was an independent predictor of readmission within 30 days of discharge. In addition, there was no significant difference in baseline, 1- and 2-year patient-reported outcomes measures between groups. Our study suggests that psychologic disorders, like depression and anxiety, are independently associated with higher all-cause 30-day readmission rates after elective spine surgery.

 Obstructive hydrocephalus in patients with posterior fossa tumors is frequently seen. Treatment options include immediate tumor removal or prior cerebrospinal fluid (CSF) diversion procedures. The necessity and feasibility of an ETV in these situations has not yet been proven in adult patients.  We retrospectively reviewed our prospectively maintained database for ETVs before surgery of posterior fossa tumors in adults. The primary focus of data analyses was the question of whether the ETV was suitable to treat the acute situation of hydrocephalus without an increased rate of complications due to the special anatomical situation with a posterior fossa tumor. We also analyzed whether any further CSF diverting procedures were necessary.  A total of 40 adult patients who underwent an ETV before posterior fossa tumor surgery were analyzed. Overall, 33 patients (82.5%) had clinical signs of hydrocephalus, and all of them improved in their clinical course after ETV. Seven patients (17.5%) did not demonstrate clinical signs of hydrocephalus, but ETV was performed with prophylactic or palliative intent in six patients and one patient, respectively. No complications were observed due to ETV itself. No permanent shunting procedure was necessary in a mean follow-up of 76.5 months. Early additional CSF diverting procedures (redo ETV, external ventricular drain) were performed in five patients (12.5%).  The present series confirms the feasibility and safety of ETV before posterior fossa tumor surgery in adult patients. If patients had symptomatic hydrocephalus before tumor surgery, an ETV can be performed, followed by early elective tumor surgery. A prophylactic ETV in asymptomatic patients is not advised. Early elective tumor surgery should be performed in these patients. Georg Thieme Verlag KG Stuttgart · New York.

Aim: A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Background: Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can’t tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. Materials and Methods: A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Results: Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. Conclusion: This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay

To better define the prevalence and location of full-thickness articular cartilage lesions in elite football players undergoing knee magnetic resonance imaging (MRI) at the National Football League (NFL) Invitational Combine and assess the association of these lesions with previous knee surgery. We performed a retrospective review of all participants in the NFL Combine undergoing a knee MRI scan from 2005 to 2009. Each MRI scan was reviewed for evidence of articular cartilage disease. History of previous knee surgery including anterior cruciate ligament reconstruction, meniscal procedures, and articular cartilage surgery was recorded for each athlete. Knees with a history of previous articular cartilage restoration surgery were excluded from the analysis. A total of 704 knee MRI scans were included in the analysis. Full-thickness articular cartilage lesions were associated with a history of any previous knee surgery (P < .001) and, specifically, previous meniscectomy (P < .001) but not with anterior cruciate ligament reconstruction (P = .7). Full-thickness lesions were present in 27% of knees with a previous meniscectomy compared with 12% of knees without any previous meniscal surgery. Full-thickness lesions in the lateral compartment were associated with previous lateral meniscectomy (P < .001); a similar relation was seen for medial meniscus tears in the medial compartment (P = .01). Full-thickness articular cartilage lesions of the knee were present in 17.3% of elite American football players at the NFL Combine undergoing MRI. The lateral compartment appears to be at greater risk for full-thickness cartilage loss. Previous knee surgery, particularly meniscectomy, is associated with these lesions.

The neutrophil to lymphocyte ratio (NLR), has been proposed as potential indicator of cardiovascular events. Our aim was to determine the relationship between NLR and development of myocardial injury after non-cardiac surgery (MINS). This observational cohort study included 255 consecutive noncardiac surgery patients aged ≥45 years. Electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels of the patients were obtained for a period of 3 days postoperatively. MINS was detected in 30 (11.8%) patients using the cut-off level of ≥14 ng/L for hscTnT. In the MINS group NLR (3.79 ± 0.7 vs. 2.69 ± 0.6, p < 0.000) values were higher than non-NLR group. The NLR to be independently associated with the development of MINS (OR: 11.690; CI: 4.619-29.585, p < 0.000). NLR seems to be a simple, easy and cheap tool to predict the development of MINS in patient undergoing non-cardiac surgery. Copyright © 2018 Elsevier Inc. All rights reserved.

Tranexamic acid for reducing mortality in emergency and urgent surgery.

Emergency or urgent surgery, which can be defined as surgery which must be done promptly to save life, limb, or functional capacity, is associated with a high risk of bleeding and death. Antifibrinolytic agents, such as tranexamic acid, inhibit blood clot breakdown (fibrinolysis) and can reduce perioperative bleeding. Tranexamic acid has been shown to reduce the need for a blood transfusion in adult patients undergoing elective surgery but its effects in patients undergoing emergency or urgent surgery is unclear.   To assess the effects of tranexamic acid on mortality, blood transfusion and thromboembolic events in adults undergoing emergency or urgent surgery. We searched the following electronic databases: the Cochrane Injuries Group's Specialised Register (22 August 2012); Cochrane Central Register of Controlled Trials (2012, issue 8 of 12); MEDLINE (Ovid SP) 1950 to August Week 2, 2012; PubMed 1 June 2012 to 22 August 2012; EMBASE (Ovid SP) 1980 to 2012 Week 33; ISI Web of Science: Conference Proceedings Citation Index-Science (CPCI-S) 1990 to 22 August 2012; ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED) 1970 to 22 August 2012. We also searched online trial registers on 22 August 2012 to identify unpublished studies. Randomised controlled trials comparing tranexamic acid with no tranexamic acid or placebo in adults undergoing emergency or urgent surgery. Two authors examined titles, abstracts and keywords of citations from the electronic databases for eligibility and extracted data for analysis and risk of bias assessment. Outcome measures of interest were mortality, receipt of a blood transfusion, units of blood transfused, reoperation, seizures and thromboembolic events (myocardial infarction, stroke, deep vein thrombosis and pulmonary embolism). We identified five trials involving 372 people that met the inclusion criteria. Three trials (260 patients) contributed data to the analyses. The effect of tranexamic acid on mortality (RR 1

To describe how older patients experience the healthcare chain and information given before, during and after colorectal cancer surgery. Most persons with colorectal cancer are older than 70 years and undergo surgery with subsequent enhanced recovery programmes aiming to quickly restore preoperative function. However, adaptation of such programmes to suit the older patient has not been made. Qualitative descriptive study. Semi-structured interviews were conducted on 16 patients undergoing colorectal cancer surgery at a Swedish University Hospital. The inductive content analysis was employed. During the period of primary investigation and diagnosis, a paucity of information regarding the disease and management, and lack of help in coping with the diagnosis of cancer and its impact on future life, leads to a feeling of vulnerability. During their stay in hospital, the patient's negative perception of the hospital environment, their need for support, and uncertainty and anxiety about the future are evident. After discharge, rehabilitation is perceived as lacking in structure and individual adaptation, leading to disappointment. Persistent difficulty with nutrition delays recovery, and confusion regarding division of responsibility between primary and specialist care leads to increased anxiety and feelings of vulnerability. Information on self-care is perceived as inadequate. Furthermore, provided information is not always understood and therefore not useful. Information before and after surgery must be tailored to meet the needs of older persons, considering the patient's knowledge and ability to understand. Furthermore, individual nutritional requirements and preoperative physical activity and status must be taken into account when planning rehabilitation. Patient information must be personalised and made understandable. This can improve self-preparation and participation in the own recovery. Special needs must be addressed early and followed up. © 2018 John Wiley

Despite demonstrated efficacy of ϵ-aminocaproic acid (EACA) in reducing blood loss in adolescents undergoing spinal fusion, there are no population-specific pharmacokinetic data to guide dosing. The aim of this study was to determine the pharmacokinetics of EACA in adolescents undergoing spinal fusion surgery and make dosing recommendations. Twenty children ages 12-17 years were enrolled, with 10 children in each of two groups based on diagnosis (idiopathic scoliosis or non-idiopathic scoliosis). Previously reported data from infants undergoing craniofacial surgery were included in the model to enable dosing recommendations over a wide range of weights, ages, and diagnoses. A population non-linear mixed effects modelling approach was used to characterize EACA pharmacokinetics. Population pharmacokinetic parameters were estimated using a two-compartment disposition model with allometrically scaled weight and an age effect on clearance. Pharmacokinetic parameters for the typical patient were a plasma clearance of 153 ml min(-1) 70 kg(-1) (6.32 ml min(-1) kg(-0.75)), intercompartmental clearance of 200 ml min(-1) 70 kg(-1) (8.26 ml min(-1) kg(-0.75)), central volume of distribution of 8.78 litre 70 kg(-1) (0.13 litre kg(-1)), and peripheral volume of distribution of 15.8 litre 70 kg(-1) (0.23 litre kg(-1)). Scoliosis aetiology did not have a clinically significant effect on drug pharmacokinetics. The following dosing schemes are recommended according to patient weight: weight <25 kg, 100 mg kg(-1) loading dose and 40 mg kg(-1) h(-1) infusion; weight ≤25 kg-<50 kg, 100 mg kg(-1) loading dose and 35 mg kg(-1) h(-1) infusion; and weight ≥50 kg, 100 mg kg(-1) loading dose and 30 mg kg(-1) h(-1) infusion. An efficacy trial employing this dosing strategy is warranted. NCT01408823. © The Author 2015. Published by Oxford University Press on behalf of the British Journal of Anaesthesia.

Low serum albumin levels (hypoalbuminemia) have classically been used to identify malnutrition. The effect of increasing severity of malnutrition on postoperative outcomes in patients undergoing hip fracture surgery has not been well delineated on a large scale. Retrospective. Multicenter. A total of 12,373 patients undergoing hip fracture surgery from 2006 to 2013 National Surgery Quality Improvement Project data were identified. Patient demographic, comorbidity, and preoperative laboratory data and complication, reoperation, and readmission data were collected. Multivariate logistic regression was used to determine the effect of increasing severity of malnutrition on rates of 30-day postoperative complications, readmissions, and reoperations. A total of 12,373 hip fractures met inclusion criteria. A total of 6506 (52.6%) patients had normal albumin levels (albumin ≥3.5 g/dL), 3205 (25.9%) patients were mildly malnourished (albumin 3.1-3.49 g/dL), 2265 (18.3%) were moderately malnourished (albumin 2.4-3.1 g/dL), and 397 (3.2%) patients were severely malnourished (albumin <2.4 g/dL). Mean age was similar between the 4 cohorts (P < 0.001). Severe malnutrition was associated with a 2-fold increase in the odds of postoperative complications and mortality when compared with mild malnutrition (P < 0.001). Increasing severity of malnutrition was associated with significantly longer lengths of stay and higher odds of experiencing a related readmission (P < 0.001). Increasing severity of hypoalbuminemia is independently associated with poorer outcomes in the 30 days after hip fracture surgery. Prognostic Level III.

Context Music and surgery. Objective To determine the effect of live classical piano music on vital signs of patients undergoing ophthalmic surgery. Design Retrospective case series. Setting and Patients 203 patients who underwent various ophthalmologic procedures in a period during which a piano was present in the operating room of St. Francis Medical Center. [Note: St. Francis Medical Center has recently been renamed Hawaii Medical Center East.] Intervention Demographic data, surgical procedures, and the vital signs of 203 patients who underwent ophthalmic procedures were obtained from patient records. Blood pressure, heart rate, and respiratory rate measured in the preoperative holding area were compared with the same parameters taken in the operating room, with and without exposure to live piano music. A paired t-test was used for statistical analysis. Main outcome measure Mean arterial pressure, heart rate, and respiratory rate. Results 115 patients who were exposed to live piano music showed a statistically significant decrease in mean arterial blood pressure, heart rate, and respiratory rate in the operating room compared with their vital signs measured in the preoperative holding area (P < .0001). The control group of 88 patients not exposed to live piano music showed a statistically significant increase in mean arterial blood pressure (P < .0002) and heart rate and respiratory rate (P < .0001). Conclusion Live classical piano music lowered the blood pressure, heart rate, and respiratory rate in patients undergoing ophthalmic surgery. PMID:18679538

Surgical site infections (SSIs), commonly caused by methicillin-resistant Staphylococcus aureus (MRSA), are associated with significant morbidity and mortality, specifically when hardware is implanted in the patient. Previously, we have demonstrated that a preoperative decontamination protocol using chlorhexidine gluconate washcloths and intranasal antiseptic ointment is effective in eradicating MRSA in the nose and on the skin of patients. To examine the effect of a decontamination protocol on SSIs in patients undergoing elective orthopedic surgery with hardware implantation. A prospective database of patients undergoing elective orthopedic surgery with hardware implantation at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, Texas, was analyzed from October 1, 2012, to December 31, 2013. Cohort groups before and after the intervention were compared. Starting in May 2013, during their preoperative visit, all of the patients watched an educational video about MRSA decontamination and were given chlorhexidine washcloths and oral rinse and nasal povidone-iodine solution to be used the night before and the morning of scheduled surgery. Thirty-day SSI rates were collected according to the definitions of the Centers for Disease Control and Prevention National Nosocomial Infections Surveillance. Data on demographics, comorbidities such as chronic obstructive pulmonary disease and coronary artery disease, tobacco use, alcohol use, and body mass index were also collected. Univariate analysis was performed between the 2 groups of patients. Multivariate analysis was used to identify independent predictors of SSI. A total of 709 patients were analyzed (344 controls and 365 patients who were decolonized). Both groups were well matched with no significant differences in age, body mass index, sex, or comorbidities. All of the patients (100%) completed the MRSA decontamination protocol. The SSI rate in the intervention group was significantly lower (1.1%; 4 of

A prospective, nonrandomized study. To evaluate the effectiveness of periodic intraoperative text messages (SMS) in reducing parental anxiety level during posterior spinal fusion (PSF) surgery for adolescent idiopathic scoliosis (AIS) patients. No studies have reported the use of intraoperative SMS to reduce level of anxiety in parents of patients who are undergoing AIS corrective surgery. Parents of 50 AIS patients were studied at two centers. Group 1 did not receive any SMS whereas those in Group 2 received periodic SMS. Parents' anxiety were assessed using a validated Visual Analog Scale for anxiety (VAS-A) and the anxiety component of the Hospital Anxiety Depression Score (HADS). The assessment was carried out at five different periods: (P1) 6 hours before the surgery; (P2) at separation in the operation theatre; (P3) 1 hour after commencement of surgery; (P4) immediately after completion of surgery; (P5) 1 day postsurgery. A total of 96 parents (47 fathers, 49 mothers) were involved in this study. Both groups were comparable in terms of demographics and education level. The mean VAS for Group 1 peaked at P2 and the HADS scores peaked at P3. The anxiety level of Group 1 remained high at P2, P3, and P4. There was a steady decline in parental anxiety in Group 2 from P1 to P5. There were significantly lower mean VAS score and HADS score for both father and mother in Group 2 during P3 and P4. The mean HADS scores for parents in Group 1 at P2 and P3 were higher than 8, which indicate abnormal anxiety. The anxiety levels of parents receiving the SMS were significantly lower than parents who did not receive any messages. Thus, intraoperative SMS is an effective intervention to decrease parental anxiety of AIS patients undergoing PSF surgery. 3.

To develop and evaluate an individualized fluid therapy in the elderly patients with coronary heart disease undergoing gastrointestinal surgery. In this prospective study, 60 coronary heart disease patients undergoing gastrointestinal surgery were included in the First Affiliated Hospital of Xinjiang Medical University from March 2009 to March 2012. Patients were randomized into the intervention group and the control group with 30 patients in each group. Individualized fluid therapy was used during surgery and postoperative period in the ICU, which was determined based on target controlled fluid therapy according to cardiac index, stroke volume, and stroke volume variation. Traditional fluid therapy was used in the control group in the intraoperative and postoperative period. The two groups were compared in terms of postoperative hemodynamic parameters, total fluid volume, incidence of adverse cardiac events, and recovery of bowel function. Compared with the control group, mean arterial pressure was significantly increased at the commencement of the surgery. The cardiac index was significantly elevated during surgery and at the end of the surgery. Stroke volume was significantly increased after induction of anesthesia, during the surgery, and at the early stay of ICU period(all P<0.05). Serum lactic acid in the intervention group was significantly lower at the end of surgery and during ICU stay than that in the control group (all P<0.05). During surgery and 24-hour stay in ICU, the total fluid volume, crystal usage, and urine were significantly less, while colloidal fluid use was significantly more in the intervention group as compared to the control group(all P<0.05). The perioperative adverse cardiac event rate was 36.7%(11/30) in the intervention group, lower than 56.7%(17/30) in the control group, but the difference was no statistically significance(P>0.05). In the intervention group, defecation time, time to first flatus, resumption of liquid intake, length of

In people with haemophilia or other congenital bleeding disorders undergoing surgical interventions, haemostatic treatment is needed in order to correct the underlying coagulation abnormalities and minimise the bleeding risk. This treatment varies according to the specific haemostatic defect, its severity and the type of surgical procedure. The aim of treatment is to ensure adequate haemostatic coverage for as long as the bleeding risk persists and until wound healing is complete. To assess the effectiveness and safety of different haemostatic regimens (type, dose and duration, modality of administration and target haemostatic levels) administered in people with haemophilia or other congenital bleeding disorders for preventing bleeding complications during and after surgical procedures. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews.Date of the last search: 20 November 2014. Randomised and quasi-randomised controlled trials comparing any hemostatic treatment regimen to no treatment or to another active regimen in children and adults with haemophilia or other congenital bleeding disorders undergoing any surgical intervention. Two authors independently assessed trials (eligibility and risks of bias) and extracted data. Meta-analyses were performed on available and relevant data. Of the 16 identified trials, four (112 participants) were eligible for inclusion.Two trials evaluated 59 people with haemophilia A and B undergoing 63 dental extractions. Trials compared the use of a different type (tranexamic acid or epsilon-aminocaproic acid) and regimen of antifibrinolytic agents as haemostatic support to the initial replacement treatment. Neither trial specifically addressed mortality (one of this review's primary outcomes); however, in the frame

Objective Reconstructive surgery to improve psychological well-being is commonly offered to children with craniofacial conditions. Few studies have explored the challenges of reconstructive surgery beyond the physical risks: poor treatment outcomes, infection, brain damage, and death. This qualitative study aims to understand the psychological and social implications such interventions can have for individuals with craniofacial conditions. Design A total of 38 individuals between the ages of 12 and 61 with such craniofacial conditions as Sturge-Weber syndrome, Treacher Collins syndrome, Möbius syndrome, cleft lip and palate, Noonan syndrome, Crouzon syndrome, and amniotic band syndrome participated in semistructured video-recorded interviews. Participants were recruited at conferences, through study flyers, and by word of mouth. Descriptive, thematic analysis was used to identify themes related to reconstructive surgery. Results Dominant themes included undergoing surgery to reduce stigmatization, the psychological and social implications of the interventions, outcome satisfaction, parental involvement in decision making about surgery, and recommendations for parents considering surgery for their children with craniofacial conditions. Experiences with reconstructive surgery varied, with some participants expressing surgical benefits and others, disillusionment. Conclusions The range of participant attitudes and experiences reflect the complexity of reconstructive surgery. Pediatric health care teams involved in the care of children with craniofacial conditions play an important role in advising patients (and their parents) about existing treatment options. The psychological and social implications of reconstructive surgery should be relayed to help families weigh the risks and benefits of surgery in an informed and meaningful way. PMID:22315960

Multislice computed tomography (MSCT) is a non-invasive, less expensive, low-radiation alternative to coronary angiography (CAG) prior to valvular heart surgery. MSCT has a high negative predictive value for coronary artery disease (CAD) but previous studies of patients with valvular disease have shown that MSCT, as the primary evaluation technique, lead to re-evaluation with CAG in about a third of cases and it is therefore not recommended. If a subgroup of patients with low- to intermediate risk of CAD could be identified and examined with MSCT, it could be cost-effective, reduce radiation and the risk of complications associated with CAG. The study cohort was derived from a national registry of patients undergoing CAG prior to valvular heart surgery. Using logistic regression, we identified significant risk factors for CAD and developed a risk score (CT-valve score). The score was validated on a similar cohort of patients from another registry. The study cohort consisted of 2221 patients, 521 (23.5%) had CAD. The validation cohort consisted of 2575 patients, 771 (29.9%) had CAD. The identified risk factors were male sex, age, smoking, hyperlipidemia, hypertension, aortic valve disease, extracardiac arteriopathy, ejection fraction <30% and diabetes mellitus. CT-valve score could identify a third of the population with a risk about 10%. A score based on risk factors of CAD can identify patients that might benefit from using MSCT as a gatekeeper to CAG prior to heart valve surgery. Copyright © 2016 Elsevier Ireland Ltd.

A pragmatic multi-centre randomised controlled trial of fluid loading and level of dependency in high-risk surgical patients undergoing major elective surgery: trial protocol

PubMed Central

2010-01-01

Background Patients undergoing major elective or urgent surgery are at high risk of death or significant morbidity. Measures to reduce this morbidity and mortality include pre-operative optimisation and use of higher levels of dependency care after surgery. We propose a pragmatic multi-centre randomised controlled trial of level of dependency and pre-operative fluid therapy in high-risk surgical patients undergoing major elective surgery. Methods/Design A multi-centre randomised controlled trial with a 2 * 2 factorial design. The first randomisation is to pre-operative fluid therapy or standard regimen and the second randomisation is to routine intensive care versus high dependency care during the early post-operative period. We intend to recruit 204 patients undergoing major elective and urgent abdominal and thoraco-abdominal surgery who fulfil high-risk surgical criteria. The primary outcome for the comparison of level of care is cost-effectiveness at six months and for the comparison of fluid optimisation is the number of hospital days after surgery. Discussion We believe that the results of this study will be invaluable in determining the future care and clinical resource utilisation for this group of patients and thus will have a major impact on clinical practice.

To determine the effects of milrinone on short-term mortality in cardiac surgery patients with focus on the presence or absence of heterogeneity of the effect. A systematic review and meta-analysis. Five hundred thirty-seven adult cardiac surgery patients from 12 RCTs. Milrinone administration. The authors conducted a systematic Medline and Pubmed search to assess the effect of milrinone on short-term mortality in adult cardiac surgery patients. Subanalysis was performed according to the timing for commencement of milrinone administration and the type of comparators. The primary outcome was any short-term mortality. Overall analysis showed no difference in mortality rates in patients who received milrinone and patients who received comparators (odds ratio = 1.25, 95% CI 0.45-3.51, p = 0.67). In subanalysis for the timing to commence milrinone administration and the type of comparators, odds ratio for mortality varied from 0.19 (placebo as control drug, start of administration after cardiopulmonary bypass) to 2.58 (levosimendan as control drug, start of administration after cardiopulmonary bypass). Among RCTs to assess the effect of milrinone administration in adult cardiac surgery patients, there are wide variations of the odds ratios of administration of milrinone for short-term mortality according to the comparators and the timing of administration. This fact may suggest that a simple pooling meta-analysis is not applicable for assessing the risk and benefit of milrinone administration in an adult cardiac surgery cohort.

Obesity exacerbates pre-existing musculoskeletal disease and joint pain. This may limit physical activity in obese individuals. We sought to identify the disease burden and impact of osteoarthritis of the lumbar back, hip, knee, and ankle in veterans undergoing bariatric surgery. Veterans Affairs medical center. Retrospective review of a prospective bariatric database of operations performed at a single Veterans Affairs medical center. Patients with osteoarthritis of the lumbar spine, hip, knee, or ankle were identified and diagnosis confirmed by electronic health record review of prior radiographic reports. Analysis was performed using χ 2 test for continuous variables. Student's t test and one-way analysis of variance were used to compare qualitative variables. Of 254 bariatric surgical patients, 83.9% had preoperative musculoskeletal pain before bariatric surgery and 59.1% had a confirmed diagnosis of osteoarthritis of the lumbar spine, hips, knees, and/or ankles. Follow-up rate was 97.4%, 85.4%, and 82.6% at 1, 3, and 5 years respectively. Of patients with osteoarthritis, 58.6% had knee involvement and 46% had multiple sites involved. In the cohort without osteoarthritis, percent excess body mass index loss was 66.9% at 1 year versus 58.5% in the cohort with osteoarthritis (P = .009), 66.1% versus 51.9% (P = .001) at 3 years, and 64.3% versus 50.1% (P = .002) after 5 years. Percent total weight loss was 28.4% versus 25.2%, 28.0% versus 22.8%, and 27.1% versus 22.4%, respectively, at 1, 3, and 5 years. Osteoarthritis is common among veterans undergoing bariatric surgery. It is associated with significantly less weight loss compared to veterans who do not have osteoarthritis, up to 5 years after bariatric surgery. Published by Elsevier Inc.

In this prospective study, multiplex polymerase chain reaction (PCR) was used to identify genes encoding virulence factors (ica, atlE and mecA) in Coagulase-negative Staphylococcus (CNS) isolates from the ocular microbiota of patients undergoing cataract surgery and to investigate possible changes in the CNS profile due to antibiotic prophylaxis. Between 09/2011 and 08/2013, patients undergoing cataract surgery were recruited at the Department of Ophthalmology, National University of Asuncion, Paraguay. In the eye to be operated on, patients received moxifloxacin 0.5 % eye drops four times at the day before surgery and a last drop 1 hour before surgery (T1). The other eye remained as control (T0). Conjunctival swabs were taken from both eyes 1 hour after the last drop. The presence of genes encoding biofilm formation (ica and atlE) and methicillin resistance (mecA) was detected by a multiplex PCR. Of the 162 patients (162 study eyes, 162 fellow eye as control group), 87 (53.7 %) eyes were positive for CNS at T0 yielding 96 CNS isolates; 70 eyes (43.2 %) were positive at T1 yielding 77 CNS isolates. For this study, 43 CNS isolates (44.8 %) from T0 and 45 (64.3 %) from T1 were used. Of the total isolates, 81.8 % (72/88) had at least one virulence factor gene (37/43 from T0 and 35/45 from T1) (p = 0.314). Simultaneous detection of ica and atlE genes was higher in T0 (58.0 %) than T1 (46.7 %), but the difference was not significant (p = 0.28). A high frequency of genes encoding virulence factors was observed in the coagulase-negative Staphylococcus isolates. The use of moxifloxacin did not significantly modify the CNS virulence factor profiles.

Cardiovascular effects of total intravenous anesthesia using ketamine-medetomidine-propofol drug combination (KMP-TIVA) were determined in 5 Thoroughbred horses undergoing surgery. The horses were anesthetized with intravenous administration (IV) of ketamine (2.5 mg/kg) and midazolam (0.04 mg/kg) following premedication with medetomidne (5 µg/kg, IV) and artificially ventilated. Surgical anesthesia was maintained by controlling propofol infusion rate (initially 0.20 mg/kg/min following an IV loading dose of 0.5 mg/kg) and constant rate infusions of ketamine (1 mg/kg/hr) and medetomidine (1.25 µg/kg/hr). The horses were anesthetized for 175 ± 14 min (range from 160 to 197 min). Propofol infusion rates ranged from 0.13 to 0.17 mg/kg/min, and plasma concentration (Cpl) of propofol ranged from 11.4 to 13.3 µg/ml during surgery. Cardiovascular measurements during surgery remained within clinically acceptable ranges in the horses (heart rate: 33 to 37 beats/min, mean arterial blood pressure: 111 to 119 mmHg, cardiac index: 48 to 53 ml/kg/min, stroke volume: 650 to 800 ml/beat and systemic vascular resistance: 311 to 398 dynes/sec/cm5). The propofol Cpl declined rapidly after the cessation of propofol infusion and was significantly lower at 10 min (4.5 ± 1.5 µg/ml), extubation (4.0 ± 1.2 µg/ml) and standing (2.4 ± 0.9 µg/ml) compared with the Cpl at the end of propofol administration (11.4 ± 2.7 µg/ml). All the horses recovered uneventfully and stood at 74 ± 28 min after the cessation of anesthesia. KMP-TIVA provided satisfactory quality and control of anesthesia with minimum cardiovascular depression in horses undergoing surgery. PMID:25409552

The incidence of hip fracture is increasing and it is more common with increasing age. Surgery is used for almost all hip fractures. Blood loss occurs as a consequence of both the fracture and the surgery and thus red blood cell transfusion is frequently used. However, red blood cell transfusion is not without risks. Therefore, it is important to identify the evidence for the effective and safe use of red blood cell transfusion in people with hip fracture. To assess the effects (benefits and harms) of red blood cell transfusion in people undergoing surgery for hip fracture. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (31 October 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library, 2014, Issue 10), MEDLINE (January 1946 to 20 November 2014), EMBASE (January 1974 to 20 November 2014), CINAHL (January 1982 to 20 November 2014), British Nursing Index Database (January 1992 to 20 November 2014), the Systematic Review Initiative's Transfusion Evidence Library, PubMed for e-publications, various other databases and ongoing trial registers. Randomised controlled trials comparing red blood cell transfusion versus no transfusion or an alternative to transfusion, different transfusion protocols or different transfusion thresholds in people undergoing surgery for hip fracture. Three review authors independently assessed each study's risk of bias and extracted data using a study-specific form. We pooled data where there was homogeneity in the trial comparisons and the timing of outcome measurement. We used GRADE criteria to assess the quality (low, moderate or high) of the evidence for each outcome. We included six trials (2722 participants): all compared two thresholds for red blood cell transfusion: a 'liberal' strategy to maintain a haemoglobin concentration of usually 10 g/dL versus a more 'restrictive' strategy based on symptoms of anaemia or a lower haemoglobin concentration, usually 8 g/dL.

Abstract Enhanced recovery after surgery (ERAS) is increasingly used in several abdominal surgeries to accelerate postoperative recovery and reduce the length of stay. The aim of this study was to investigate the pattern of functional recovery after gastrectomy in patients undergoing ERAS and to analyze factors that affect postoperative recovery. In all, 168 gastric cancer patients enrolled in a clinical trial evaluating ERAS compliance after gastrectomy were prospectively assessed with respect to postoperative functional recovery using discharge criteria, evaluating 4 major functional outcomes: adequate pain control, ability to mobilize and self-care, tolerance of oral intake, and no abnormal physical findings or laboratory test. The mean completion time of overall discharge criteria was 5.1 ± 3.2 days. The mean completion time for each dimension were 4.4 ± 0.9 days for adequate pain control, 4.1 ± 0.8 days for ability to mobilize and self-care, 4.3 ± 1.1 days for no abnormal physical signs or laboratory test, and 4.6 ± 1.2 days for tolerance of oral intake. The mean length of stay was 7.2 ± 3.2 days, and readmission rate was 2.4% (n = 4). There was 9.5% (n = 16) of morbidity and no hospital mortality. Female sex (P < 0.001) and age (≥65 years; P = 0.049) were significantly associated with a slower recovery in tolerance of oral intake, and total gastrectomy was significantly associated with delayed completion of adequate pain control (P = 0.003). Functional recovery after gastrectomy can be achieved after about 5 days in patients undergoing ERAS. Female sex, old age, and total gastrectomy are factors that delay normal functional recovery after gastrectomy. PMID:27057836

The use of administrative billing data may enable large-scale assessments of treatment outcomes for Chiari Malformation type I (CM-1). However, to utilize such data sets, validated International Classification of Diseases, Ninth Revision (ICD-9-CM) code algorithms for identifying CM-1 surgery are needed. To validate 2 ICD-9-CM code algorithms identifying patients undergoing CM-1 decompression surgery. We retrospectively analyzed the validity of 2 ICD-9-CM code algorithms for identifying adult CM-1 decompression surgery performed at 2 academic medical centers between 2001 and 2013. Algorithm 1 included any discharge diagnosis code of 348.4 (CM-1), as well as a procedure code of 01.24 (cranial decompression) or 03.09 (spinal decompression, or laminectomy). Algorithm 2 restricted this group to patients with a primary diagnosis of 348.4. The positive predictive value (PPV) and sensitivity of each algorithm were calculated. Among 340 first-time admissions identified by Algorithm 1, the overall PPV for CM-1 decompression was 65%. Among the 214 admissions identified by Algorithm 2, the overall PPV was 99.5%. The PPV for Algorithm 1 was lower in the Vanderbilt (59%) cohort, males (40%), and patients treated between 2009 and 2013 (57%), whereas the PPV of Algorithm 2 remained high (≥99%) across subgroups. The sensitivity of Algorithms 1 (86%) and 2 (83%) were above 75% in all subgroups. ICD-9-CM code Algorithm 2 has excellent PPV and good sensitivity to identify adult CM-1 decompression surgery. These results lay the foundation for studying CM-1 treatment outcomes by using large administrative databases.

Stainless steel wiring remains the most popular technique for primary sternal closure. Recently, a multifilament cable wiring system (Pioneer Surgical Technology Inc., Marquette, MI, USA) was introduced for sternal closure and has gained wide acceptance due to its superior resistance to tension. We aimed to compare conventional steel wiring to multifilament cable fixation for sternal closure in patients undergoing major cardiac surgery. Data were collected retrospectively on 1,354 patients who underwent sternal closure after major cardiac surgery, using either the multifilament cable wiring system or conventional steel wires between January 2009 and October 2010. The surgical outcomes of these two groups of patients were compared using propensity score matching based on 18 baseline patient characteristics. Propensity score matching yielded 392 pairs of patients in the two groups whose baseline profiles showed no significant differences. No significant differences between the two groups were observed in the rates of early mortality (2.0% vs. 1.3%, p=0.578), major wound complications requiring reconstruction (1.3% vs. 1.3%, p>0.99), minor wound complications (3.6% vs. 2.0%, p=0.279), or mediastinitis (0.8% vs. 1.0%, p=1.00). Patients in the multifilament cable group had fewer sternal bleeding events than those in the conventional wire group, but this tendency was not statistically significant (4.3% vs. 7.4%, p=0.068). The surgical outcomes of sternal closure using multifilament cable wires were comparable to those observed when conventional steel wires were used. Therefore, the multifilament cable wiring system may be considered a viable option for sternal closure in patients undergoing major cardiac surgery.

Interdisciplinary management of elderly patients requiring spine surgery has been shown to improve short- and long-term outcomes. The aim of this study was to determine whether an interdisciplinary team approach mitigates use of intensive care unit (ICU) resources. A unique comanagement model for elderly patients undergoing lumbar fusion surgery was implemented at a major academic medical center. The Peri-operative Optimization of Senior Health Program (POSH) was launched with the aim of improving outcomes in elderly patients (>65 years old) undergoing complex lumbar spine surgery. In this model, a geriatrician evaluates elderly patients preoperatively, comanages daily throughout hospital course, and coordinates multidisciplinary rehabilitation, along with the neurosurgical team. We retrospectively reviewed the first 100 cases after the initiation of the POSH protocol and compared them with the immediately preceding 25 cases to assess the rates of ICU transfer and independent predictors of ICU admission. A total of 125 patients undergoing lumbar decompression and fusion surgery were enrolled in this pilot program. Baseline characteristics and intraoperative variables, as well as number of fusion levels and duration of surgery, were similar between both cohorts. There was a significant difference in the use of ICU services (ICU admission rates) between both cohorts, with the non-POSH cohort having a 3-fold increase compared with the POSH cohort (P < 0.0001). In a multivariate analysis, lack of an interdisciplinary comanagement team approach was an independent predictor for ICU transfers in elderly patients undergoing corrective surgery (odds ratio 8.51, 95% confidence interval 2.972-24.37, P < 0.0001). Our study suggests that an interdisciplinary comanagement model between geriatrics and neurosurgery is independently associated with reduced use of critical care services.

Routine sentinel lymph node (SLN) surgery during prophylactic mastectomy (PM) is unnecessary, because most PMs do not contain cancer. Our institution utilizes intraoperative pathology to guide the surgical decision for resection of SLNs in PM. The purpose of this study was to review the effectiveness of this approach. We identified all women aged ≥18 years who underwent bilateral PM (BPM) or contralateral PM (CPM) at our institution from January 2008 to July 2016. We evaluated the frequency of SLN resection and rate of occult breast cancer (DCIS or invasive disease) in the PM. We used the following definitions: over-treatment-SLN surgery in patients without cancer; under-treatment-no SLN surgery in patients with cancer; appropriate treatment-no SLN in patients without cancer or SLN surgery in patients with cancer. PM was performed on 1900 breasts: 1410 (74.2%) CPMs and 490 (25.8%) BPMs. Cancer was identified in 58 (3.0%) cases (32 invasive disease and 26 DCIS) and concurrent SLN surgery was performed in 44 (75.9%) of those cases. Overall, SLN surgery guided by intraoperative pathology resulted in appropriate treatment of 1787 (94.1%) cases: 1319 (93.5%) CPMs and 468 (95.5%) BPMs, by avoiding SLN in 1743/1842 cases without cancer (94.6%), and performing SLN surgery in 44/58 cases with cancer (75.9%). Use of intraoperative pathology to direct SLN surgery in patients undergoing PM minimizes over-treatment from routine SLN in PM and minimizes under-treatment from avoiding SLN in PM, demonstrating the value of intraoperative pathology in this era of focus on appropriateness of care.

With emphasis on value-based health care, empiric models are used to estimate expected readmission rates for individual institutions. The aim of this study was to determine the relationship between distance traveled to seek surgical care and likelihood of readmission in adult patients undergoing cardiac operations at a single medical center. All adults undergoing major cardiac surgeries from 2008 to 2015 were included. Patients were stratified by travel distance into regional and distant travel groups. Multivariable logistic regression models were developed to assess the impact of distance traveled on odds of readmission. Of the 4232 patients analyzed, 29 per cent were in the regional group and 71 per cent in the distant. Baseline characteristics between the two groups were comparable except mean age (62 vs 61 years, P < 0.01) and Caucasian race (59 vs 73%, P < 0.01). Distant travel was associated with a significantly longer hospital length of stay (11.8 vs 10.5 days, P < 0.01) and lower risk of readmission (9.5 vs 13.4%, P < 0.01). Odds of readmission was inversely associated with logarithm of distance traveled (odds ratio 0.75). Travel distance in patients undergoing major cardiac surgeries was inversely associated with odds of readmission.

: Randomized, placebo-controlled trial. : To evaluate the efficacy of epsilon aminocaproic acid (EACA) to reduce the number of red-cell (RBC) transfusions in adult patients undergoing major spinal surgery. : Reconstructive spinal surgery is associated with significant blood loss. The number of studies evaluating the efficacy of EACA in adult patients undergoing spinal surgery remains scarce and limited. : EACA (100 mg/kg) or placebo was administered to 182 adult patients after the induction of anesthesia followed by an infusion that was continued for 8 hours after surgery. Primary end points included total allogeneic RBC transfusions through postoperative day 8 and postoperative allogeneic plus autologus RBC transfusions through postoperative day 8. : Mean total allogeneic RBC transfusions were not statistically different between the groups (5.9 units EACA vs. 6.9 units placebo; P = 0.17). Mean postoperative RBC transfusions in the EACA group was less (2.0 units vs. 2.8 units placebo; P = 0.03). There was no significantdifference in mean estimated intraoperative estimated-blood loss (2938 cc EACA vs. 3273 cc placebo; P = 0.32). Mean intensive care unit length of stay was decreased (EACA: 1.8 days vs. 2.8 days placebo; P = 0.04). The incidence of thromboembolic complications was similar (2.2% EACA vs. 6.6% placebo; P = 0.15). : The difference in total allogeneic RBC transfusions between the groups was not statistically significant. EACA was associated with a 30% (0.8 units) reduction in postoperative RBC transfusions and a 1-day reduction in ICU LOS, without an increased incidence of thromboembolic events. EACA may be considered for patients undergoing major spinal surgery. Larger studies are needed to evaluate the relationship between EACA and total RBC requirements.

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

Perioperative thermal disturbances during orthotopic liver transplantation (OLT) are common. We hypothesized that in patients undergoing OLT the use of a humidified high flow CO 2 warming system maintains higher intraoperative temperatures when compared to standardized multimodal strategies to maintain thermoregulatory homeostasis. We performed a randomized pilot study in adult patients undergoing primary OLT. Participants were randomized to receive either open wound humidification with a high flow CO 2 warming system in addition to standard care (Humidification group) or to standard care alone (Control group). The primary end point was nasopharyngeal core temperature measured 5 min immediately prior to reperfusion of the donor liver (Stage 3 - 5 min). Secondary endpoints included intraoperative PaCO 2 , minute ventilation and the use of vasoconstrictors. Eleven patients were randomized to each group. Both groups were similar for age, body mass index, MELD, SOFA and APACHE II scores, baseline temperature, and duration of surgery. Immediately prior to reperfusion (Stage 3 - 5 min) the mean (SD) core temperature was higher in the Humidification Group compared to the Control Group: 36.0 °C (0.13) vs. 35.4 °C (0.22), p = 0.028. Repeated measured ANOVA showed that core temperatures over time during the stages of the transplant were higher in the Humidification Group compared to the Control Group (p < 0.0001). There were no significant differences in the ETCO 2 , PaCO 2 , minute ventilation, or inotropic support. The humidified high flow CO 2 warming system was superior to standardized multimodal strategies in maintaining normothermia in patients undergoing OLT. Use of the device was feasible and did not interfere with any aspects of surgery. A larger study is needed to investigate if the improved thermoregulation observed is associated with improved patient outcomes. ACTRN12616001631493 . Retrospectively registered 25 November 2016.

Postoperative delirium is a common preventable complication experienced by older adults undergoing elective surgery. In this systematic review and meta-analysis, we identified prognostic factors associated with the risk of postoperative delirium among older adults undergoing elective surgery. Medline, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and AgeLine were searched for articles published between inception and April 21, 2016. A total of 5692 titles and abstracts were screened in duplicate for possible inclusion. Studies using any method for diagnosing delirium were eligible. Two reviewers independently completed all data extraction and quality assessments using the Cochrane Risk-of-Bias Tool for randomized controlled trials (RCTs) and the Newcastle-Ottawa Scale (NOS) for cohort studies. Random effects meta-analysis models were used to derive pooled effect estimates. Forty-one studies (9384 patients) reported delirium-related prognostic factors. Among our included studies, the pooled incidence of postoperative delirium was 18.4% (95% confidence interval [CI] 14.3-23.3%, number needed to follow [NNF] = 6). Geriatric syndromes were important predictors of delirium, namely history of delirium (odds ratio [OR] 6.4, 95% CI 2.2-17.9), frailty (OR 4.1, 95% CI 1.4-11.7), cognitive impairment (OR 2.7, 95% CI 1.9-3.8), impairment in activities of daily living (ADLs; OR 2.1, 95% CI 1.6-2.6), and impairment in instrumental activities of daily living (IADLs; OR 1.9, 95% CI 1.3-2.8). Potentially modifiable prognostic factors such as psychotropic medication use (OR 2.3, 95% CI 1.4-3.6) and smoking status (OR 1.8 95% CI 1.3-2.4) were also identified. Caregiver support was associated with lower odds of postoperative delirium (OR 0.69, 95% CI 0.52-0.91). Though caution must be used in interpreting meta-analyses of non-randomized studies due to the potential influence of unmeasured confounding, we identified potentially modifiable prognostic factors including

Obstructive sleep apnea (OSA) is a common comorbidity in patients undergoing cardiac surgery and may predispose patients to postoperative complications. The purpose of this meta-analysis is to determine the evidence of postoperative complications associated with OSA patients undergoing cardiac surgery. A literature search of Cochrane Database of Systematic Reviews, Medline, Medline In-process, Web of Science, Scopus, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL until October 2016 was performed. The search was constrained to studies in adult cardiac surgical patients with diagnosed or suspected OSA. All included studies must report at least 1 postoperative complication. The primary outcome is major adverse cardiac or cerebrovascular events (MACCEs) up to 30 days after surgery, which includes death from all-cause mortality, myocardial infarction, myocardial injury, nonfatal cardiac arrest, revascularization process, pulmonary embolism, deep venous thrombosis, newly documented postoperative atrial fibrillation (POAF), stroke, and congestive heart failure. Secondary outcome is newly documented POAF. The other exploratory outcomes include the following: (1) postoperative tracheal intubation and mechanical ventilation; (2) infection and/or sepsis; (3) unplanned intensive care unit (ICU) admission; and (4) duration of stay in hospital and ICU. Meta-analysis and meta- regression were conducted using Cochrane Review Manager 5.3 (Cochrane, London, UK) and OpenBUGS v3.0, respectively. Eleven comparative studies were included (n = 1801 patients; OSA versus non-OSA: 688 vs 1113, respectively). MACCEs were 33.3% higher odds in OSA versus non-OSA patients (OSA versus non-OSA: 31% vs 10.6%; odds ratio [OR], 2.4; 95% confidence interval [CI], 1.38-4.2; P = .002). The odds of newly documented POAF (OSA versus non-OSA: 31% vs 21%; OR, 1.94; 95% CI, 1.13-3.33; P = .02) was higher in OSA compared to non-OSA. Even though the postoperative tracheal intubation and

The number of adolescents undergoing weight loss surgery (WLS) has increased in response to the increasing prevalence of severe childhood obesity. Adolescents undergoing WLS require unique support, which may differ from adult programs. The aim of this study was to describe institutional and programmatic characteristics of centers participating in Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS), a prospective study investigating safety and efficacy of adolescent WLS. Data were obtained from the Teen-LABS database, and site survey completed by Teen-LABS investigators. The survey queried (1) institutional characteristics, (2) multidisciplinary team composition, (3) clinical program characteristics, and (4) clinical research infrastructure. All centers had extensive multidisciplinary involvement in the assessment, pre-operative education, and post-operative management of adolescents undergoing WLS. Eligibility criteria and pre-operative clinical and diagnostic evaluations were similar between programs. All programs have well-developed clinical research infrastructure, use adolescent-specific educational resources, and maintain specialty equipment, including high weight capacity diagnostic imaging equipment. The composition of clinical team and institutional resources is consistent with current clinical practice guidelines. These characteristics, coupled with dedicated research staff, have facilitated enrollment of 242 participants into Teen-LABS. © 2013 Published by Elsevier Inc.

Both transversus abdominis plane (TAP) block and combined ilioinguinal-iliohypogastric (IIN/IHN) blocks are used routinely under ultrasound (USG) guidance for postoperative pain relief in patients undergoing inguinal hernia surgery. This study compares USG guided TAP Vs IIN/IHN block for post-operative analgesic efficacy in adults undergoing inguinal hernia surgery. Sixty adults aged 18 to 60 with American Society of Anesthesiologsts' grade I or II were included. After general anaesthesia, patients in Group I received USG guided unilateral TAP block using 0.75% ropivacaine 3 mg/kg (maximum 25 mL) and those in Group II received IIN/IHN block using 10 mL 0.75% ropivacaine. Postoperative rescue analgesia was with tramadol (intravenous) IV ± diclofenac IV in the first 4 h followed by oral diclofenac subsequently. Total analgesic consumption in the first 24 h was the primary objective, intraoperative haemodynamics, number of attempts and time required for performing the block as well as the postoperative pain scores were also evaluated. Time to first analgesic request was 319.8 ± 115.2 min in Group I and 408 ± 116.4 min in Group II ( P = 0.005). Seven patients (23.33%) in Group I and two (6.67%) in Group II required tramadol in first four hours. No patient in either groups received diclofenac IV. The average dose of tablet diclofenac was 200 ± 35.96 mg in Group I and 172.5 ± 34.96 mg in Group II ( P = 0. 004). USG guided IIN/IHN block reduces the postoperative analgesic requirement compared to USG guided TAP block.

Atelectasis and pleural effusion are common after coronary artery bypass graft surgery (CABG). Longer stay in the bed is one of the most important contributing factors in pulmonary complications. Some studies confirm the benefits of early mobilization (EM) in critically ill patients, but the efficacy of EM on pulmonary complications after CABG is not clear. This study was designed to examine the effect of EM on the incidence of atelectasis and pleural effusion in patients undergoing CABG. In a single-blinded randomized clinical trial, 100 patients who were undergoing coronary artery bypass graft surgery were randomly assigned into two groups each consisted of 50 patients. Patients in the experimental group were enrolled in a mobilization protocol consisting of the mobilization from the bed in the first 3 days after surgery in the morning and evening. Patients in the control group were mobilized from bed in third postoperation day, according to the hospital routine. Arterial blood gases, pleural effusion, and atelectasis were compared between groups. Atelectasis and pleural effusion was reduced in experimental group. The partial pressure of oxygen in arterial blood in third postoperative day and the percentage of arterial oxygen saturation in the fourth postoperative day were higher in the intervention group (P value < .05). EM from bed could be an effective intervention in reducing atelectasis and pleural effusion in patients undergoing CABG. Copyright © 2017 Society for Vascular Nursing, Inc. Published by Elsevier Inc.

With the withdrawal of aprotinin from worldwide marketing in November 2007, many institutions treating patients at high risk for hyperfibrinolysis had to update their therapeutic protocols. At our institution, the standard was switched from aprotinin to ε-aminocaproic acid (EACA) in all patients undergoing cardiac surgery with extracorporeal circulation including neonates. Although both antifibrinolytic medications have been used widely for many years, there are few data directly comparing their blood-sparing effect and their side-effects especially in neonates. Perioperative data from 235 neonates aged up to 30 days undergoing primary cardiac surgery were analysed. Between July 1, 2006 and November 5, 2007, all patients (n=95) received aprotinin. Starting November 6, 2007 until December 31, 2009, all patients (n=140) were treated with EACA. The primary outcome criterion was blood loss; secondary outcome criteria were transfusion requirements, renal, vascular, and neurological complications and also in-hospital mortality. All descriptive and intraoperative data variable were similar. Blood loss was significantly higher in the EACA group (P=0.001), but there was no difference in the rate of re-operation for bleeding (P=0.218) nor the number of transfusions. There were no differences in the incidences of postoperative renal, neurological, and vascular events or in-hospital mortality. In neonatal patients undergoing cardiac surgery, the switch to EACA treatment led to a higher postoperative blood loss. However, there were no differences in transfusion requirements or major clinical outcomes.

Enhanced recovery after surgery (ERAS) integrates evidence-based interventions to reduce surgical stress and accelerate rehabilitation. Our study was to compare the short-term quality of life (QOL) in patients undergoing open colonic surgery using ERAS program or conventional management. A prospective study of 57 patients using ERAS program and 60 patients using conventional management was conducted. The clinical characteristics of all patients were recorded. QOL was evaluated longitudinally using the questionnaires (EORTC QLQ-C30 and QLQ-CR29) pre- and postoperatively. Generalized estimating equation was used to do the analysis in order to determine the effective impact of correlative factors on the postoperative QOL, including age, sex, BMI, ASA grade, tumor location, tumor size, pTNM stage, recovery program and length of time after surgery. The morbidity in ERAS and control group was 17.5 versus 26.7 % (p = 0.235). The patients in ERAS group had much faster rehabilitation and less hospital stay. In the primary statistical analysis, the scores of global QOL (on POD3, POD6, POD10, POD14, POD21), physical functioning (on POD3, POD6, POD10, POD14, POD21), role functioning (on POD6, POD10, POD14, POD21), emotional functioning (on POD3, POD6, POD10, POD14, POD21), cognitive functioning (on POD3, POD6) and social functioning (on POD3, POD6, POD10, POD14, POD21, POD28) were higher in ERAS group than in control group, which suggested that the patients in ERAS group had a better life status. However, the scores of pain (on POD10, POD14, POD21), appetite loss (on POD3, POD6), constipation (on POD3, POD6, POD10), diarrhea (on POD3, POD10), financial difficulties (on POD10, POD14, POD21), perspective of future health (on POD6, POD10, POD14), gastrointestinal tract problems (on POD3, POD6, POD10) and defecation problems (on POD6, POD10, POD14) were lower in ERAS group than in control group, which revealed that the patients in ERAS group suffered less symptoms.

Postoperative throat complaints such as postoperative sore throat (POST), dysphagia, and hoarseness frequently arises after tracheal intubation and throat packing for patient undergoing general anesthesia. This condition is very disturbing to patient. Avoiding POST is a major priority for these patients because preventing postoperative complications contributes to patient satisfaction. To describe and analyze the postoperative throat effects of nasopharyngeal packing and oropharyngeal packing in patients undergoing nasal surgery. A randomized comparative study. After obtaining approval of Ethical Committee 40 patients were included in study. After this patient were randomly allocated into two groups of 20 each. Group A - in which the oropharynx was packed and Group B - inwhich the nasopharynx was packed. General anesthesia were given and throat packing was done and patients were interviewed postoperatively for any throat complications such as sore throat, difficulty in swallowing (dysphagia), hoarseness of voice, throat irritation, and any other symptom pertaining to the study were noted and data were analyzed. T-test to compare the age, while Chi-square test and Fisher's exact test were used to compare sex distribution, sore throat, dysphagia, hoarseness, and throat irritation. Results showed statistically significant difference in incidence and severity of POST in Group A patients when compared to Group B patients to be more. Patients in Group A had a higher incidence of dysphagia when compared to their Group B counterparts. With respect to the incidence of hoarseness and throat irritation, there was no statistical significance between the groups. We concluded that the site of pharyngeal packing influences the incidence and severity of POST and as well as the incidence of dysphagia after general anesthesia. The use of nasopharyngeal packing in the patients undergoing nasal surgeries might lead to a reduction of the same.

Atrial fibrillation is a common post-operative complication of cardiac surgery and is associated with an increased risk of post-operative stroke, increased length of intensive care unit and hospital stays, healthcare costs and mortality. Numerous trials have evaluated various pharmacological and non-pharmacological prophylactic interventions for their efficacy in preventing post-operative atrial fibrillation. We conducted an update to a 2004 Cochrane systematic review and meta-analysis of the literature to gain a better understanding of the effectiveness of these interventions. The primary objective was to assess the effects of pharmacological and non-pharmacological interventions for preventing post-operative atrial fibrillation or supraventricular tachycardia after cardiac surgery. Secondary objectives were to determine the effects on post-operative stroke or cerebrovascular accident, mortality, cardiovascular mortality, length of hospital stay and cost of treatment during the hospital stay. We searched the Cochrane Central Register of ControlLed Trials (CENTRAL) (Issue 8, 2011), MEDLINE (from 1946 to July 2011), EMBASE (from 1974 to July 2011) and CINAHL (from 1981 to July 2011). We selected randomized controlled trials (RCTs) that included adult patients undergoing cardiac surgery who were allocated to pharmacological or non-pharmacological interventions for the prevention of post-operative atrial fibrillation or supraventricular tachycardia, except digoxin, potassium (K(+)), or steroids. Two review authors independently abstracted study data and assessed trial quality. One hundred and eighteen studies with 138 treatment groups and 17,364 participants were included in this review. Fifty-seven of these studies were included in the original version of this review while 61 were added, including 27 on interventions that were not considered in the original version. Interventions included amiodarone, beta-blockers, sotalol, magnesium, atrial pacing and posterior

In this study we investigated the effects of preoperative oral carbohydrate administration on postoperative insulin resistance (PIR), gastric fluid volume, preoperative discomfort, and variables of organ dysfunction in ASA physical status III-IV patients undergoing elective cardiac surgery, including those with noninsulin-dependent Type-2 diabetes mellitus. Before surgery, 188 patients were randomized to receive a clear 12.5% carbohydrate drink (CHO), flavored water (placebo), or to fast overnight (control). CHO and placebo were treated in double-blind format and received 800 mL of the corresponding beverage in the evening and 400 mL 2 h before surgery. Patients were monitored from induction of general anesthesia until 24 h postoperatively. Exogenous insulin requirements to control blood glucose levels surgery does not affect PIR. Clear fluids reduce thirst and may be recommended as a safe procedure in ASA III-IV patients. Further research is indicated to investigate possible cardioprotective effects of preoperative CHO intake.

Our primary objective was to assess the feasibility of geriatric patients (>65 yr) bypassing the postanesthesia care unit (PACU) after ambulatory surgery. A secondary objective was to compare recovery profiles when using three different maintenance anesthetics. Ninety ASA physical status I--III consenting outpatients (>65 yr) undergoing short urologic procedures were randomly assigned to one of three anesthetic treatment groups. After a standardized induction with fentanyl and propofol, anesthesia was maintained with propofol (75-150 microg center dot kg(-1) center dot min(-1) IV), isoflurane (0.7%-1.2% end tidal), or desflurane (3%-6% end tidal), in combination with nitrous oxide 70% in oxygen. In all three groups, the primary anesthetic was titrated to maintain an electroencephalographic-bispectral index value of 60-65. Recovery times, postanesthesia recovery scores, and therapeutic interventions in the PACU were recorded. Although emergence times were similar in the three groups, the time to achieve a fast-track discharge score of 14 was significantly shorter in patients receiving desflurane compared with propofol and isoflurane (22 +/- 23 vs 33 +/- 25 and 44 +/- 36 min, respectively). On arrival in the PACU, a significantly larger percentage of patients receiving desflurane were judged to be fast-track eligible compared with those receiving either isoflurane and propofol (73% vs 43% and 44%, respectively). The number of therapeutic interventions in the PACU was also significantly larger in the Isoflurane group when compared with the Propofol and Desflurane groups (21 vs 11 and 7, respectively). In conclusion, use of desflurane for maintenance of anesthesia should facilitate PACU bypass ("fast-tracking") of geriatric patients undergoing short urologic procedures. Geriatric outpatients undergoing brief urologic procedures more rapidly achieve fast-tracking discharge criteria after desflurane (versus isoflurane and propofol) anesthesia. Use of isoflurane was also

Adults with hemophilia A (HA), hemophilia B (HB), and von Willebrand disease (VWD) frequently require surgery and invasive procedures. However, there is variability in perioperative management guidelines. We describe our periprocedural outcomes in this setting. A retrospective chart review from January 2006 to December 2012 of patients with HA, HB, and VWD undergoing surgery or invasive procedures was conducted. Type of procedures, management including the use of continuous factor infusion, and administration of antifibrinolytics were reviewed. Adverse outcomes were defined as acute bleeding (<48 hours), delayed bleeding (≥48 hours), transfusion, inhibitor development, and thrombosis. We identified 59 patients with HA and HB. In all, 24 patients had severe hemophilia and 12 had mild/moderate hemophilia. Twelve patients had inhibitors. There were also 5 female carriers of HA and 6 patients with VWD. There were 34 major surgeries (26 orthopedic, 8 nonorthopedic) and 129 minor surgeries. Continuous infusion was used in 55.9% of major surgeries versus 8.5% of minor surgeries. Antifibrinolytics were administered in 14.7% of major surgeries versus 23.2% of minor surgeries. In all, 4 patients developed acute bleeding and 10 patients developed delayed bleeding. Delayed bleeding occurred in 28.6% of genitourinary procedures and in 16.1% of dental procedures. Five patients acquired an inhibitor and 2 had thrombosis. In conclusion, patients with HA, HB, or VWD had similar rates of adverse outcomes when undergoing minor surgeries or major surgeries. This finding underscores the importance of an interdisciplinary management and procedure-specific guidelines for patients with hemophilia and VWD prior to even minor invasive procedures.

Heart disease is a disabling condition and necessary surgical intervention is often lacking in many developing countries. Training of the superspecialties abroad is largely limited to observation with little or no opportunity for hands on experience. An approach in which open heart surgeries are conducted locally by visiting teams enabling skills transfer to the local team and helps build to build capacity has been adopted at the Uganda Heart Institute (UHI). We reviewed the progress of open heart surgery at the UHI and evaluated the postoperative outcomes and challenges faced in conducting open heart surgery in a developing country. Medical records of patients undergoing open heart surgery at the UHI from October 2007 to June 2012 were reviewed. A total of 124 patients underwent open heart surgery during the study period. The commonest conditions were: venticular septal defects (VSDs) 34.7% (43/124), Atrial septal defects (ASDs) 34.7% (43/124) and tetralogy of fallot (TOF) in 10.5% (13/124). Non governmental organizations (NGOs) funded 96.8% (120/124) of the operations, and in only 4 patients (3.2%) families paid for the surgeries. There was increasing complexity in cases operated upon from predominantly ASDs and VSDs at the beginning to more complex cases like TOFs and TAPVR. The local team independently operated 19 patients (15.3%). Postoperative morbidity was low with arrhythmias, left ventricular dysfunction and re-operations being the commonest seen. Post operative sepsis occurred in only 2 cases (1.6%). The overall mortality rate was 3.2. Open heart surgery though expensive is feasible in a developing country. With increased direct funding from governments and local charities to support open heart surgeries, more cardiac patients access surgical treatment locally.

Nonalcoholic steatohepatitis (NASH) is a silent liver disease that can lead to inflammation and subsequent scaring. If left untreated, cirrhosis may ensue. Morbidly obese patients are at an increased risk of NASH. We report the prevalence and predictors of NASH in patients undergoing morbid obesity surgery. A retrospective review was conducted on morbidly obese patients undergoing weight reduction surgery from September 2005 through December 2008. A liver biopsy was performed at the time of surgery. Patients who had a history of hepatitis infection or previous alcohol dependency were excluded. Prevalence of NASH was studied. Predictors of NASH among clinical and biochemical variables were analyzed using multivariate regression analysis. One hundred thirteen patients were analyzed (84% female; mean age, 42.6 ± 11.4 years; mean body mass index, 45.1 ± 5.7 kg/m(2)). Sixty-one patients had systemic hypertension (54%) and 35 patients had diabetes (31%). The prevalence of NASH in this study population was 35 per cent (40 of 113). An additional 59 patients (52%) had simple steatosis without NASH. Only 14 patients had normal liver histology. On multivariate analysis, only elevated aspartate aminotransferase (AST) (greater than 41 IU/L) was the independent predictor for NASH (odds ratio, 5.85; confidence interval, 1.06 to 32.41). Patient age, body mass index, hypertension, diabetes, hypercholesterolemia, and abnormal alanine aminotransferase did not predict NASH. NASH is a common finding in obese population. Abnormal AST was the only predictive factor for NASH.

Patients who undergo major surgery are at risk for perioperative morbidity and mortality. It would be appropriate to initiate advance care planning with patients prior to surgery, but surgeons may experience difficulty initiating such conversations. Rather than focus on changing clinician behavior, advance care planning decision aids can be an innovative vehicle to motivate advance care planning among surgical patients and their families. The purpose of this paper is to describe a study protocol for conducting an environmental scan concerning advance care planning decision aids that may be relevant to patients undergoing high-risk surgery. This study will gather information from written or verbal data sources that incorporate professional and lay perspectives: a systematic review, a grey literature review, key informant interviews, and patient and family engagement. It is envisioned that this study will generate three outcomes: a synthesis of current evidence, a summary of gaps in knowledge, and a taxonomy of existing advance care planning decision aids. This environmental scan will demonstrate principles of patient-centered outcomes research, and it will exemplify a pioneering approach for reviewing complex interventions. Anticipated limitations are that information will be gathered from a small sample of patients and families, and that potentially relevant information could also be missing from the environmental scan due to the inclusion/exclusion criteria. Outcomes from the environmental scan will inform future patient-centered research to develop and evaluate a new decision aid.

: Preoperative anxiety is a critical issue in children, and associated with postoperative behavioral changes. : The purpose of the current study is to evaluate how audiovisual and auditory presentations about the perioperative period impact preoperative anxiety and postoperative behavioral disturbances of children undergoing elective ambulatory surgery. : A total of 99 patients between the ages of 5-12, scheduled to undergo outpatient surgery, participated in this study. Participants were randomly assigned to one of three groups; audiovisual group (Group V, n = 33), auditory group (Group A, n = 33), and control group (Group C, n = 33). During the evaluation, the Modified Yale Preoperative Anxiety Scale (M-YPAS) and the posthospitalization behavioral questionnaire (PHBQ) were used. : There were no significant differences in demographic characteristics between the groups. M-YPAS scores were significantly lower in Group V than in Groups C and A (P < 0.001 and P < 0.001, respectively). PHBQ scores in Group C were statistically higher than in Groups A and V, but, no statistical difference was found between Groups A and V. Compared to auditory presentations, audiovisual presentations, in terms of being memorable and interesting, may be more effective in reducing children's anxiety. In addition, we can suggest that both methods can be equally effective for postoperative behavioral changes.

To describe the use of antibiotics for urinary tract infection (UTI) before and after surgery for urinary incontinence (UI); and for those with use of antibiotics before surgery, to estimate the risk of treatment for a postoperative UTI, relative to those without use of antibiotics before surgery. A historical population-based cohort study. Denmark. Women (age ≥18 years) with a primary surgical procedure for UI from the county of Funen and the Region of Southern Denmark from 1996 throughout 2010. Data on redeemed prescriptions of antibiotics ±365 days from the date of surgery were extracted from a prescription database. Use of antibiotics for UTI in relation to UI surgery, and the risk of being a postoperative user of antibiotics for UTI among preoperative users. A total of 2151 women had a primary surgical procedure for UI; of these 496 (23.1%) were preoperative users of antibiotics for UTI. Among preoperative users, 129 (26%) and 215 (43.3%) also redeemed prescriptions of antibiotics for UTI within 0-60 and 61-365 days after surgery, respectively. Among preoperative non-users, 182 (11.0%) and 235 (14.2%) redeemed prescriptions within 0-60 and 61-365 days after surgery, respectively. Presurgery exposure to antibiotics for UTI was a strong risk factor for postoperative treatment for UTI, both within 0-60 days (adjusted OR, aOR=2.6 (95% CI 2.0 to 3.5)) and within 61-365 days (aOR=4.5 (95% CI 3.5 to 5.7)). 1 in 4 women undergoing surgery for UI was treated for UTI before surgery, and half of them had a continuing tendency to UTIs after surgery. Use of antibiotics for UTI before surgery was a strong risk factor for antibiotic use after surgery. In women not using antibiotics for UTI before surgery only a minor proportion initiated use after surgery.

The changing demographics of the adult congenital heart disease (CHD) population requires an understanding of the factors that impact patient survival to adulthood. We sought to investigate sex differences in CHD surgical mortality in children. Children <18 years old hospitalized for CHD surgery were identified using the Kids' Inpatient Database in 2000, 2003, and 2006. Demographic, diagnostic, and procedural variables were grouped according to RACHS-1 (Risk Adjustment for Congenital Heart Surgery) method. Logistic regression was used to determine the odds ratio of death in females versus males adjusting for RACHS-1 risk category, age, prematurity, major noncardiac anomalies, and multiple procedures. Analyses were stratified by RACHS-1 risk categories and age. Of 33 848 hospitalizations for CHD surgery, 54.7% were in males. Males were more likely than females to have CHD surgery in infancy, high-risk CHD surgery, and multiple CHD procedures. Females had more major noncardiac structural anomalies and more low-risk procedures. However, the adjusted risk of in-hospital death was higher in females (odds ratio, 1.21; 95% confidence interval, 1.08 to 1.36) on account of the subgroup with high-risk surgeries who were <1 year of age (odds ratio, 1.39; 95% confidence interval, 1.16 to 1.67). In this large US population study, more male children underwent CHD surgery and had high-risk procedures. Female infants who had high-risk procedures were at higher risk for death, but this accounted for a small proportion of females and is therefore unlikely to have a major impact on the changing demographics in adults in CHD.

The relationship between the transfusion of red blood cell (RBC) units and outcomes in patients undergoing cardiac surgery is the subject of intense debates. In this study, we investigated the relationship between the transfusion of 1-2 leucocyte-depleted (LD) RBC units and outcomes in patients undergoing open-heart valve surgery. The investigation encompassed consecutive patients undergoing open-heart valve surgery at our institution between July 2009 and March 2015 who received no (RBC- group) or 1-2 units of LD RBC (RBC+ group). End-points were 30-day mortality (primary), the incidence of in-hospital major organ dysfunctions and 1-year mortality (secondary). Propensity score (PS)-adjusted statistical analysis was used to assess the effect of RBC transfusion on end-points. Thirty-day mortality rate was 0.2% (3/1485) in the RBC- group and 0.4% (6/1672) in the RBC+ group, with a PS-adjusted odds ratio (OR) for 30-day mortality of 1.00 (95% CI: 0.21-4.83;P = 0.99). The two groups showed no significant differences in PS-adjusted ORs for major complications, such as stroke, low cardiac output syndrome, thoracic wound infection and prolonged mechanical ventilation (>24 h). The PS-adjusted ORs for prolonged intensive care unit stay (>48 h) were, however, significantly higher in the RBC+ group (OR = 1.34 [95%CI: 1.04-1.72; P = 0.02]) than in the RBC- group. One-year mortality was comparable between groups (PS-adjusted hazard ratio for the RBC+ group: 0.85 [95% CI: 0.42-1.72; P = 0.65]). Our data do not provide evidence that in patients undergoing valve surgery with cardiopulmonary bypass, transfusion of 1-2 units of LD RBC increases operative mortality, the incidence of postoperative complications or 1-year mortality. © The Author 2016.

Surgical repair is a common treatment for inguinal hernias but a substantial number of patients experience chronic pain after surgery. As some patients are pain-free on presentation, it is important to investigate whether patients perceive the treatment to be beneficial. The present study used qualitative methods to explore experiences of pain, activity limitations and satisfaction with treatment as people underwent surgery and recovery. Twenty-nine semi-structured interviews were conducted. Seven participants were interviewed longitudinally: before surgery and two weeks and four months post-surgery. Ten further participants with residual pain four months post-surgery were interviewed once. Semi-structured interviews included experience and perception of pain; activity limitations; reasons for having surgery; satisfaction with the decision to undergo surgery. A thematic analysis was conducted. Pain did not cause concern when perceived as part of the usual surgery and recovery processes. Activity was limited to avoid damage to the hernia site rather than to avoid pain. None of the participants reported dissatisfaction with the decision to have surgery; reducing the risk of life-threatening complications associated with untreated hernias was considered important. These findings suggest that people regarded surgical treatment as worthwhile, despite chronic post-surgical pain. Further research should ascertain whether patients are aware of the actual risk of complications associated with conservative rather than surgical management of inguinal hernia. PMID:26973903

Undergoing surgery is an anxious experience for children. Applying anxiety reduction age-appropriate programs by nurses would be beneficial in reducing anxiety to children. To test the effectiveness of age-appropriate preoperative information session in reducing anxiety levels of school-age children undergoing elective surgery in Jordan. The study used a quasi-experimental design. One hundred and twenty-six children were recruited from an educational hospital in Amman from January to June 2012 and were randomly assigned to intervention and control groups. The anxiety levels of children were assessed using the State Anxiety Scale for children, and children's levels of cooperation after surgery were assessed using Children Emotional Manifestation Scale. The heart rate and blood pressure of children were also measured 1 hour before going to operation room. The study results revealed that children in the intervention group reported lower anxiety levels and more cooperation than children in the control group. Also, they displayed lower heart rate and blood pressure than children in the control group. The application of age-appropriate preoperative intervention for children could be beneficial in decreasing anxiety levels and increasing their cooperation post surgery. © 2018 John Wiley & Sons Australia, Ltd.

Leg ischemia is a serious complication of femoral artery cannulation. The primary aim of this study was to assess the safety and efficacy of a novel bidirectional femoral arterial cannula (Sorin Group USA, a wholly owned subsidiary of LivaNova PLC, Arvada, CO USA) that provides both antegrade and retrograde flow, in patients undergoing peripheral cannulation for cardiopulmonary bypass during cardiac surgery. Patients undergoing routine cardiac surgery requiring femoral artery cannulation for cardiopulmonary bypass were identified preoperatively. Informed written consent was obtained in all cases. Bidirectional cannula insertion used either a surgical cut-down and wire through needle approach or a percutaneous technique. Flow in the superficial femoral artery was assessed using Doppler ultrasound after commencement of cardiopulmonary bypass. Lower limb perfusion was assessed using reflectance near-infrared spectroscopy to measure regional oxygen saturations in the cannulated limb during cardiopulmonary bypass. Fifteen patients (median age = 61.3 years, range = 26-79 years, 10 males, 5 females) underwent femoral arterial cannulation using the novel bidirectional femoral cannula between August 2016 and May 2017. Fourteen cannulae were inserted directly into the femoral artery via a surgical cut-down and wire through needle technique. One bidirectional cannula was inserted using a percutaneous insertion technique. Indications included minimally invasive mitral and aortic valve surgery, thoracic aortic aneurysm repair, and redo cardiac surgery. The median duration of cardiopulmonary bypass was 129 minutes (range = 53-228 minutes). The cannula was inserted and positioned without difficulty in 14 of 15 patients. Incorrect sizing and arterial spasm prevented correct cannula positioning in one patient. Antegrade flow in the superficial femoral artery was observed on Doppler ultrasound in 12 of 12 patients in which this was performed. Continuous stable distal perfusion was

Management of the axilla in patients with early-stage breast cancer (ESBC) has evolved. Recent trials support less extensive axillary surgery in patients undergoing mastectomy. We examine factors affecting regional lymph node (RLN) surgery and outcomes in patients with ESBC undergoing mastectomy. Women with clinical T1/2 N0 M0 invasive BC who underwent mastectomy with 1-2 positive nodes were selected from the National Cancer Database (2004-2015). Axillary surgery was defined by number of RLNs examined: 1-5 sentinel LN dissection (SLND), and ≥ 10 axillary LND (ALND). Binary logistic regression and survival analyses were performed to assess the association between axillary surgery and clinical characteristics, and overall survival (OS), respectively. 34,243 patients were included: 13,821 SLND (40%) and 20,422 ALND (60%). SLND significantly increased from 21% (2004) to 45% (2015) (p < .001). Independent factors associated with SLND were treatment year, non-Academic centers, geographic region, tumor histology, and postmastectomy radiotherapy (PMRT). Multivariable survival analysis showed that ALND was associated with better OS (HR 0.78, 95% CI 0.72-0.83, p < .001) relative to SLND; however, there was no difference in patients with LN micrometastases treated without RT (HR 0.87, 95% CI 0.73-1.05, p = .153) or patients receiving PMRT (HR 0.92, 95% CI 0.76-1.13, p = .433). SLND has significantly increased in patients undergoing mastectomy with limited axillary disease and is influenced by patient, tumor, and treatment factors. Survival outcomes did not differ by axillary treatment for patients with LN micrometastases treated without RT or patients who received PMRT. SLND may be considered in select patients with ESBC and limited axillary disease undergoing mastectomy.

Postoperative ileus is a poorly understood multifactorial outcome following colorectal surgery that presents significant clinical challenges and contributes to increased morbidity, length of stay, and healthcare cost. To date, there are few pharmacological interventions that shorten the duration of postoperative ileus. This study is the first to evaluate the efficacy of simethicone in treating postoperative ileus symptoms in patients undergoing colorectal surgery. A multicenter, double-blinded, placebo controlled randomized controlled trial. This trial was conducted at two academic tertiary care centres in Ontario, Canada. 118 patients undergoing colorectal surgery. Patients were randomized to receive either a five-day course of oral simethicone (n = 58) or a placebo (n = 60). The primary outcome was time to first passage of flatus. Secondary outcomes included time to first bowel movement, postoperative length of stay, and postoperative pain. Statistical analyses were performed on an intention-to-treat basis. Statistical significance set at p = 0.05. The median time to first passage of flatus in simethicone arm was 25.2 h and 26.7 h in controls (P = 0.98). There were no significant differences in the median time to first bowel movement (simethicone = 41.1 h vs. control = 42.9 h, P = 0.91) or median length of hospital stay (simethicone = 4.5 days vs. control = 4.0 days, P = 0.63). This study failed to show a difference in return of gastrointestinal motility in patients receiving simethicone following colorectal surgery. Postoperative ileus remains a significant clinical and economic burden to the healthcare system and further research is needed to identify a reliable and effective method of treatment.

Objective To determine whether the probability of undergoing coronary bypass surgery within a certain time was related to the number of patients on the wait list at registration for the operation in a publicly funded health system. Methods A prospective cohort study comparing waiting times among patients registered on wait lists at the hospitals delivering adult cardiac surgery. For each calendar week, the list size, the number of new registrations, and the number of direct admissions immediately after angiography characterized the demand for surgery. Results The length of delay in undergoing treatment was associated with list size at registration, with shorter times for shorter lists (log-rank test 1,198.3, p<.0001). When the list size at registration required clearance time over 1 week patients had 42 percent lower odds of undergoing surgery compared with lists with clearance time less than 1 week (odds ratio [OR] 0.58 percent, 95 percent, confidence interval [CI] 0.53–0.63), after adjustment for age, sex, comorbidity, period, and hospital. The weekly number of new registrations exceeding weekly service capacity had an independent effect toward longer service delays when the list size at registration required clearance time less than 1 week (OR 0.56 percent, 95 percent CI 0.45–0.71), but not for longer lists. Every time the operation was performed for a patient requiring surgery without registration on wait lists, the odds of surgery for listed patients were reduced by 6 percent (OR 0.94, CI 0.93–0.95). Conclusion For wait-listed patients, time to surgery depends on the list size at registration, the number of new registrations, as well as on the weekly number of patients who move immediately from angiography to coronary bypass surgery without being registered on a wait list. Hospital managers may use these findings to improve resource planning and to reduce uncertainty when providing advice on expected treatment delays. PMID:16430599

Patient anxiety about nail surgery relates mainly to pain associated with needle puncture, anesthetic flow during the procedure, and postoperative care, as well as possible past traumatic experience. The aims of this study were to compare anxiety levels among patients undergoing nail surgery and skin punch biopsy and to assess the effects of demographic characteristics on anxiety. Forty-eight consecutive patients who were referred to a dermatological surgery unit for nail surgery intervention (group 1) and 50 age- and sex-matched patients referred to the same unit for skin punch biopsy (group 2) were enrolled in the study. Patients' anxiety levels were measured using Spielberger's State-Trait Anxiety Inventory. There was no significant difference in median anxiety level between group 1 (42.00; interquartile range, 6.50) and group 2 (41.00; interquartile range, 8.25) (P = .517). The demographic factors of patient sex, educational status, and prior surgery showed no significant effects on anxiety levels. Nail surgery does not seem to cause significantly greater anxiety than skin punch biopsy. © The Author(s) 2015.

The aim of this study is to determine whether preoperative scores on a screening measure for cognitive status (the Saint Louis University mental status examination), were associated with discharge to a location other than home in older patients undergoing surgery for deformity. Older patients (≥65 years) undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Preoperative baseline cognition was assessed using the validated Saint Louis University mental status (SLUMS) test. SLUMS is 11 questions with a maximum of 30 points. Mild cognitive impairment was defined as a SLUMS score of 21-26 points, and severe cognitive impairment as a SLUMS score of 20 points or greater. Normal cognition was defined as a SLUMS score of 27 points or more. Postoperative length of stay and discharge location were recorded on all patients. Eighty-two subjects were included, with mean ± standard deviation age of 73.26 ± 6.08 years; 51% of patients were discharged to a facility (skilled nursing or acute rehabilitation). After adjustment for demographic variables, comorbidities, and baseline cognitive impairment, patients with preoperative cognitive impairment were 4-fold more likely to be discharged to a facility (skilled nursing or acute rehabilitation) compared with patients with normal cognitive status (odds ratio [OR], 3.93). In addition, patients who were not ambulatory before surgery were also more likely to be discharged to a facility (OR, 7.14). In geriatric patients undergoing surgery for deformity correction, cognitive screening before surgery can identify patients with impaired cognitive status who are less likely than those with normal cognitive status to return home after surgery.

Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery. A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1-10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively. In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation. Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

This study was designed to evaluate the perioperative nutritional status of patients undergoing surgery for gastrointestinal cancer using Subjective Global Assessment and surgeon behavior on nutritional support. We recruited 100 patients undergoing surgery for gastrointestinal cancer in one university and two state teaching hospitals. Subjective Global Assessment was administered to evaluate preoperative and postoperative nutritional status. Fifty-two patients in the state hospitals (Group 1) and 48 in the university hospital were assessed. Anthropometric and biochemical measurements were performed. Changes in preoperative Subjective Global Assessment scores and scores at the time of discharge and types of nutritional support were compared. Subjective Global Assessment-B was regarded as moderate and Subjective Global Assessment-C as heavy malnutrition. Ten patients had Subjective Global Assessment-B and 29 had Subjective Global Assessment-C malnutrition in Group 1 and nine had Subjective Global Assessment-B and 31 had Subjective Global Assessment-C malnutrition in Group 2 during preoperative assessment. Respective numbers in postoperative assessment were 12 for Subjective Global Assessment-B and 30 for Subjective Global Assessment-C in Group 1 and 14 for Subjective Global Assessment-B and 26 for Subjective Global Assessment-C in Group 2. There was no difference between two groups. Nutritional methods according to Subjective Global Assessment evaluation in pre- and postoperative periods were not different between the groups. This study demonstrated that the malnutrition rate is high among patients scheduled for gastrointestinal cancer surgery and the number of surgeons were inadequate to provide perioperative nutritional support. Both university and state hospitals had similar shortcomings. Subjective Global Assessment is an easy and reliable test and if utilized will be helpful to detect patients requiring nutritional support.

Perioperative risk stratification is often performed using individual risk factors without consideration of the syndemic of these risk factors. We used latent class analysis (LCA) to identify the classes of comorbidities and risk factors associated with perioperative mortality in patients presenting for intraabdominal general surgery. The 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program was used to obtain a cohort of patients undergoing intraabdominal general surgery. Risk factors and comorbidities were entered into LCA models to identify the latent classes, and individuals were assigned to a class based on the highest posterior probability of class membership. Relative risk regression was used to determine the associations between the latent classes and 30-day mortality, with adjustments for procedure. A 9-class model was fit using LCA on 466,177 observations. After combining classes with similar adjusted mortality risks, 5 risk classes were obtained. Compared with the class with average mortality risk (class 4), the risk ratios (95% confidence interval) ranged from 0.020 (0.014-0.027) in the lowest risk class (class 1) to 6.75 (6.46-7.02) in the highest risk class. After adjusting for procedure and ASA physical status, the latent classes remained significantly associated with 30-day mortality. The addition of the risk class variable to a model containing ASA physical status and surgical procedure demonstrated a significant increase in the area under the receiver operator characteristic curve (0.892 vs 0.915; P < 0.0001). Latent classes of risk factors and comorbidities in patients undergoing intraabdominal surgery are predictive of 30-day mortality independent of the ASA physical status and improve risk prediction with the ASA physical status.

Cognitive impairments are observed in numerous patients following coronary bypass surgery, and piracetam are nootropic compounds that modulate cerebral functions by directly enhancing cognitive processes. The present meta-analysis was conducted to evaluate the protective effect of piracetam on the cognitive performance of patients undergoing coronary bypass surgery. The relevant studies were identified by searching Medline, EMBASE, PubMed and the Cochrane Library up to June 2013 and the pertinent bibliographies from the retrieved studies were reviewed. Data were selected from the studies according to predefined criteria. The meta-analysis included two randomized control trials involving 184 patients and including the Syndrom-Kurz test (SKT). Findings of the meta-analysis showed that following treatment the change from baseline observed in five SKT subtest scores, conducted with piracetam patients, indicated a significant advantage over those patients that were in the placebo group. The subtests included immediate pictured object recall, weighted mean difference (WMD)=0.91, 95% confidence interval (CI) 0.51–1.31, P<0.00001; delayed pictured object recall, WMD=0.74, 95% CI 0.19–1.28, P=0.008; delayed picture recognition, WMD=0.82, 95% CI 0.31–1.31, P=0.001; immediate word recall, WMD=0.87, 95% CI 0.47–1.28, P<0.0001; and letter interference, WMD=3.46, 95% CI −5.69 to −1.23, P=0.002. These results indicated that piracetam may have been effective in improving the short-term cognitive performance of patients undergoing coronary bypass surgery. High quality, well-controlled and longer randomized trials are required to corroborate this result. PMID:24396419

Emotional Distress Increases the Likelihood of Undergoing Surgery among Men with Localized Prostate Cancer.

2017-02-01

We determined whether among men with clinically localized prostate cancer, particularly men with low risk disease, greater emotional distress increases the likelihood of undergoing surgery vs radiation or active surveillance. Participants were 1,531 patients recruited from 2 academic and 3 community facilities (nonHispanic white 83%, nonHispanic black 11% and Hispanic 6%; low risk 36%, intermediate risk 49% and high risk 15%; choice of active surveillance 24%, radiation 27% and surgery 48%). Emotional distress was assessed shortly after diagnosis and after men made a treatment decision with the Distress Thermometer. We used multinomial logistic regression with robust standard errors to test if emotional distress at either point predicted treatment choice in the sample as a whole and after stratifying by D'Amico risk score. In the sample as a whole the participants who were more emotionally distressed at diagnosis were more likely to choose surgery over active surveillance (RRR 1.07; 95% CI 1.01, 1.14; p=0.02). Men who were more distressed close to the time they made a treatment choice were more likely to have chosen surgery over active surveillance (RRR 1.16; 95% CI 1.09, 1.24; p <0.001) or surgery over radiation (RRR 1.12; 95% CI 1.05, 1.19; p=0.001). This pattern was also found in men with low risk disease. Emotional distress may motivate men with low risk prostate cancer to choose more aggressive treatment. Addressing emotional distress before and during treatment decision making may reduce a barrier to the uptake of active surveillance.

2017-12-01

To study the effectiveness of dexmedetomidine used for general anesthesia maintenance in children undergoing odontotherapy in day-surgery operating room in reducing the incidence of emergence agitation (EA). Eighty children undergoing odontotherapy and under general anesthesia in day-surgery operating room were randomized into two groups, group A (n=40) and group B (n=40). Each patient in group A was administered with a bolus dose of dexmedetomidine (1.0 μg·kg⁻¹, saline diluted to 10 mL) pump-infused after intubation and a maintenance dose of 0.1-0.4 mL·(kg·h)⁻¹ followed-up until 45 min before the end of operation. Each patient in group B was administered with a bolus dose of normal saline 10 mL pump-infused after intubation and maintenance dose of 0.1-0.4 mL·(kg·h)⁻¹ followed-up until 45 min before the end of operation. Gender, age, weight, physical status according to the American Society of Anesthesiologists, perioperative heart rate (HR), mean arterial pressure (MAP), pulse oxygen saturation (SpO₂), sufentanil dosage, duration of surgery, time of extubation, time of regaining consciousness, and time to reach modified Aldrete's score≥12 were recorded. Behavior in postanesthesia care unit was rated on the four-point agitation scale. Compared with group B, decreases were observed in HR and MAP at the beginning of operation, in 10 and 30 min, 1 and 2 h after the beginning of operation, and after extubation of group A (P<0.05). Sufentanil dosage and incidence of EA during recovery of group A were also lower than those of group B (P<0.05). Time to regain consciousness and time to reach modified Aldrete's score≥12 of group A were longer than those of group B (P<0.05). No statistical difference was observed between other indexes of the two groups. As an anesthetic used for general anesthesia maintenance in children undergoing odontotherapy in day-surgery operating room, dexmedetomidine results in low incidence of EA during recovery and more stable

BACKGROUND Post-operative cognitive dysfunction (POCD) demarks cognitive decline after major surgery but has been studied to date in “healthy” adults. Although individuals with neurodegenerative disorders such as Parkinson’s disease (PD) commonly undergo elective surgery, these individuals have yet to be prospectively followed despite hypotheses of increased POCD risk. OBJECTIVE To conduct a pilot study examining cognitive change pre-post elective orthopedic surgery for PD relative to surgery and non-surgery peers. METHODS A prospective one-year longitudinal design. No-dementia idiopathic PD individuals were actively recruited along with non-PD “healthy” controls (HC) undergoing knee replacement surgery. Non-surgical PD and HC controls were also recruited. Attention/processing speed, inhibitory function, memory recall, animal (semantic) fluency, and motor speed were assessed at baseline (pre-surgery), three-weeks, three-months, and one-year post- orthopedic surgery. Reliable change methods examined individual changes for PD individuals relative to control surgery and control non-surgery peers. RESULTS Over two years we screened 152 older adult surgery or non-surgery candidates with 19 of these individuals having a diagnosis of PD. Final participants included 8 PD (5 surgery, 3 non-surgery), 47 Control Surgery, and 21 Control Non-Surgery. Eighty percent (4 of the 5) PD surgery declined greater than 1.645 standard deviations from their baseline performance on measures assessing processing speed and inhibitory function. This was not observed for the non-surgery PD individuals. CONCLUSION This prospective pilot study demonstrated rationale and feasibility for examining cognitive decline in at-risk neurodegenerative populations. We discuss recruitment and design challenges for examining post-operative cognitive decline in neurodegenerative samples. PMID:26683785

Growing scrutiny of readmissions has placed hospitals at the center of readmission prevention. Little is known, however, about hospital nursing—a critical organizational component of hospital service system—in relation to readmissions. To determine the relationships between hospital nursing factors—nurse work environment, nurse staffing, and nurse education—and 30-day readmissions among Medicare patients undergoing general, orthopedic, and vascular surgery. We linked Medicare patient discharge data, multistate nurse survey data, and American Hospital Association Annual Survey data. Our sample included 220,914 Medicare surgical patients and 25,082 nurses from 528 hospitals in 4 states (California, Florida, New Jersey, and Pennsylvania). Risk-adjusted robust logistic regressions were used for analyses. The average 30-day readmission rate was 10% in our sample (general surgery: 11%; orthopedic surgery: 8%; vascular surgery: 12%). Readmission rates varied widely across surgical procedures and could be as high as 26% (upper limb and toe amputation for circulatory system disorders). Each additional patient per nurse increased the odds of readmission by 3% (OR=1.03; 95% CI, 1.00-1.05). Patients cared in hospitals with better nurse work environments had lower odds of readmission (OR=0.97; 95% CI, 0.95-0.99). Administrative support to nursing practice (OR=0.96; 95% CI, 0.94-0.99) and nurse-physician relations (OR=0.97; 95% CI, 0.95-0.99) were 2 main attributes of the work environment that were associated with readmissions. Better nurse staffing and work environment were significantly associated with 30-day readmission, and can be considered as system-level interventions to reduce readmissions and associated financial penalties.

Literature review. To document the historical contributions from the Harvard Medical School system to the field of adult spine surgery. Despite the fact that significant contributions to the discipline of spinal surgery have derived from the Harvard system, no prior study documents the history of the Harvard spine services in a cohesive narrative. This historical perspective reviews the history of adult spine surgery within the Harvard system and outlines the significant contributions made by orthopedic and neurosurgical practitioners to the field. Literature reviews were performed from historical works, as well as scientific publications to fashion a cohesive review covering the history of spine surgery at Harvard from the early 19th century to the present. The development of the spine surgical services at the three main Harvard hospitals, and significant spine surgical personalities within the system, are discussed, including W. Jason Mixter, MD, Joseph S. Barr Sr., MD, and Marius N. Smith-Petersen, MD. Substantial developments that have arisen from the Harvard teaching hospitals include the recognition of disc herniation as the cause of radicular symptoms in the lower extremities, the description of lumbar discectomy as a surgical treatment for radicular pain, osteotomy for the correction of spinal deformity, and the first attempt to create a systematic algorithm capable of informing treatment for cervical spine trauma. Despite humble beginnings, the surgeons and scientists at Harvard have influenced nearly every facet of spine surgery over the course of the last two centuries.

The purpose of this article was to provide the literature regarding the psychological stress in the peri-operative period of adult patients undergoing operations under general anesthesia. The articles were obtained by surveying the papers published and catalogued in the Medline Pubmed interface database, Lilacs and the Biblioteca Virtual de Saúde (BVS) since 1984, crossing the headings stress, surgery, general anesthesia, psychology. Over 800 articles related to stress and surgery were analyzed with regards to their relevance to the considered subject. Eighteen articles were related to psychological stress. Their results confirmed the presence of psychological and physical stress, during the peri-operative period as well as relation between stress and de clinical post-operative recovery. There is a gap regarding in the peri-operative period. More studies on psychological influence on stress may benefit patients and help professionals during the surgical treatment.

Background: Leukemia and hematopoietic stem cell transplantation (HSCT) create physical, psychological, social, and spiritual distresses in patients. Understanding this threatening situation in adults with leukemia undergoing HSCT will assist health care professionals in providing holistic care to the patients. Objectives: The aim of the present study was exploring the perceived threat in adults with leukemia undergoing HSCT. Patients and Methods: This article is part of a longitudinal qualitative study which used the grounded theory approach and was conducted in 2009-2011. Ten adults with acute leukemia scheduled for HSCT were recruited from the Hematology–Oncology Research Center and Stem Cell Transplantation, Shariati Hospital in Tehran, Iran. A series of pre-transplant and post-transplant in-depth interviews were held in the hospital’s HSCT wards. Totally, 18 interviews were conducted. Three written narratives were also obtained from the participants. The Corbin and Strauss approach was used to analyze the data. Results: Perceived threat was one of the main categories that emerged from the data. This category included four subcategories, "inattention to the signs and symptoms", "doubt and anxiety", "perception of danger and time limitation" and "change of life conditions", which occurred in linear progression over time. Conclusion: Suffering from leukemia and experiencing HSCT are events that are uniquely perceived by patients. This threatening situation can significantly effect perception of patients and cause temporary or permanent alterations in patients' lives. Health care professionals can help these patients by deeper understanding of their experiences and effective interventions. PMID:25414863

To report on the safety and efficacy of rectus sheath blocks, 'topped-up' using bilateral rectus sheath catheters (RSCs), in patients undergoing major open urological surgery. The RSCs were inserted under ultrasound guidance into 200 patients between April 2008 and August 2011, of whom 106 patients underwent radical retropubic prostatectomy (RRP) and 94 underwent open radical cystectomy (ORC). A retrospective case-note review was undertaken. Outcomes included technical success and complication rates of the insertion and use of RSC, visual analogue pain scores, additional analgesia requirements and length of hospital stay (LOS). All RSCs were successfully placed without complication and used for a mean of 3.6 days for ORC and 2.1 days for RRP. Early removal occurred in 6.49% of patients. Low overall pain scores were reported in both groups. Patients were more likely to require a patient-controlled analgesia system in the ORC group but the overall need for additional analgesia was low in both groups, reducing significantly after the initial 24 h. In combination with an enhanced recovery programme, LOS reduced from 17.0 to 10.8 days in the ORC group and from 6.2 to 2.8 days in the RRP group. The use of RSCs appears to offer an effective and safe method of peri-operative analgesia in patients undergoing major open urological pelvic surgery. © 2013 The Authors.

to evaluate the epidemiological variables and diagnostic and therapeutic modalities related to hepatic trauma patients undergoing laparotomy in a public referral hospital in the metropolitan region of Vitória-ES. we conducted a retrospective study, reviewing charts of trauma patients with liver injuries, whether isolated or in association with other organs, who underwent exploratory laparotomy, from January 2011 to December 2013. We studied 392 patients, 107 of these with liver injury. The male: female ratio was 6.6 : 1 and the mean age was 30.12 years. Penetrating liver trauma occurred in 78.5% of patients, mostly with firearms. Associated injuries occurred in 86% of cases and intra-abdominal injuries were more common in penetrating trauma (p <0.01). The most commonly used operative technique was hepatorrhaphy and damage control surgery was applied in 6.5% of patients. The average amounts of blood products used were 6.07 units of packed red blood cells and 3.01 units of fresh frozen plasma. The incidence of postoperative complications was 29.9%, the most frequent being infectious, including pneumonia, peritonitis and intra-abdominal abscess. The survival rate of patients suffering from blunt trauma was 60%, and penetrating trauma, 87.5% (p <0.05). despite technological advances in diagnosis and treatment, mortality rates in liver trauma remain high, especially in patients suffering from blunt trauma in relation to penetrating one.

Study Design Randomized, placebo-controlled trial Objective To evaluate the efficacy of epsilon aminocaproic acid (EACA) to reduce the number of red-cell (RBC) transfusions in adult patients undergoing major spinal surgery. Summary of Background Data Reconstructive spinal surgery is associated with significant blood loss. The number of studies evaluating the efficacy of EACA in adult patients undergoing spinal surgery remains scarce and limited. Methods EACA (100 mg/kg) or placebo was administered to 182 adult patients after the induction of anesthesia followed by an infusion that was continued for 8 hours postoperatively. Primary end-points included total allogeneic RBC transfusions through postoperative day (POD) 8 and postoperative allogeneic plus autologus RBC transfusions through POD 8. Results Mean total allogeneic RBC transfusions were not statistically different between the groups (5.9 units EACA versus 6.9 units placebo; P=0.17). Mean postoperative RBC transfusions in the EACA group was less (2.0 units versus 2.8 units placebo; P=0.03). There was no significant difference in mean estimated intraoperative EBL (2938 cc EACA vs. 3273 cc placebo; P=0.32). Mean intensive care unit length of stay was decreased (EACA 1.8 days versus 2.8 days placebo; P=0.04). The incidence of thromboembolic complications was similar (2.2% EACA vs 6.6% placebo; P=0.15). Conclusions The difference in total allogeneic RBC transfusions between the groups was not statistically significant. EACA was associated with a 30% (0.8 units) reduction in postoperative RBC transfusions and a one-day reduction in ICU LOS, without an increased incidence of thromboembolic events. EACA may be considered for patients undergoing major spinal surgery. Larger studies are needed to evaluate the relationship between EACA and total RBC requirements. PMID:19730217

Does use of intraoperative cell-salvage delay recovery in patients undergoing elective abdominal aortic surgery?

Tavare, Aniket N; Parvizi, Nassim

2011-06-01

A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed was whether the use of intraoperative cell-salvage (ICS) leads to negative outcomes in patients undergoing elective abdominal aortic surgery? Altogether 305 papers were found using the reported search, of which 10 were judged to represent the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. None of the 10 papers included in the analysis demonstrated that ICS use led to significantly higher incidence of cardiac or septic postoperative complications. Similarly, length of intensive treatment unit (ITU) or hospital stay and mortality in elective abdominal aortic surgery were not adversely affected. Indeed two trials actually show a significantly shorter hospital stay after ICS use, one a shorter ITU stay and another suggests lower rates of chest sepsis. Based on these papers, we concluded that the use of ICS does not cause increased morbidity or mortality when compared to standard practise of transfusion of allogenic blood, and may actually improve some clinical outcomes. As abdominal aortic surgery inevitably causes significant intraoperative blood loss, in the range of 661-3755 ml as described in the papers detailed in this review, ICS is a useful and safe strategy to minimise use of allogenic blood.

Laparoscopic surgery is well accepted as a safe technique when performed on a third trimester pregnant woman. The aim is to describe the anaesthetic management of a group of patients undergoing this type of surgery. An analysis was made of records of 6 patients in their third trimester of pregnancy and who underwent urgent laparoscopic surgery from 2011 to 2013. The study included 6 patients, with a diagnosis of acute cholecystitis in 4 of them. The other 2 patients had acute appendicitis, both of who presented threatened preterm labour. The most frequent indications for laparoscopic surgery during the last trimester of birth were found to be acute cholecystitis and acute appendicitis. Acute appendicitis is related to an elevated risk of presenting threatened preterm labour. Copyright © 2015 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A.

Sugammadex rapidly reverses neuromuscular blockade (NMB) induced by rocuronium. NMB induced by rocuronium is prolonged in patients with liver dysfunction, because the drug is mainly excreted into the bile. However, the efficacy and safety of sugammadex in terms of reversing rocuronium-induced NMB in patients with liver dysfunction undergoing hepatic surgery have not been evaluated. This observational study investigated the efficacy and safety of sugammadex after continuous infusion of rocuronium in patients with liver dysfunction undergoing hepatic surgery. Remifentanil/propofol anesthesia was administered to 31 patients: 15 patients in the control group, and 16 patients from a group with liver dysfunction. Rocuronium (0.6 mg/kg) was administered, followed by continuous infusion. The enrolled patients were then subdivided into two groups according to the dose of sugammadex. In the first group a single dose of sugammadex (2.0 mg/kg) was given at the reappearance of the second twitch (T2). In the second group a single dose of sugammadex (4.0 mg/kg) was given at the first twitch response if T2 did not reappear in 15 minutes after stopping rocuronium. The primary outcome was time from administration of sugammadex to recovery of a train-of-four ratio to 0.9. The dose of rocuronium required in the liver dysfunction group was lower than that in the control group (6.2 vs. 8.2 μg/kg/min, p = 0.002). The mean time from the administration of sugammadex to recovery of the train-of-four ratio to 0.9 was not significantly different between the liver dysfunction group and the control group (2.2 minutes vs. 2.0 minutes in the 2 mg/kg administration group, p = 0.44 and 1.9 minutes vs. 1.7 minutes in the 4 mg/kg administration group, p = 0.70, respectively). No evidence of recurarization was observed in any of the patients. Most of the adverse events were found to be mild and such events were not related to the use of sugammadex. None of the patients was eliminated from the study

The effect of perioperative beta-blockade on the pulmonary function of patients undergoing major arterial surgery.

Concern about the potential detrimental side-effects of beta-blockade on pulmonary function often dissuades against their perioperative use in patients undergoing major arterial surgery (especially in those with chronic obstructive pulmonary disease (COPD)). In this study we aimed to establish prospectively the clinical relevance of these concerns. After ethics committee approval and individual informed consent, the pulmonary function of twenty patients (mean age 68.7 years (range 43-82), 11 males) scheduled to undergo non-emergency major vascular surgery was studied by recording symptoms and spirometry before and after institution of effective beta-blockade. Fifteen patients (75%) had significant smoking histories (mean pack years/patient=50), while 12 (60%) had COPD. All patients tolerated effective beta-blockade satisfactorily without developing either subjective deterioration in symptoms or significant change on spirometry. The mean change in FEV1 following adequate beta-blockade was 0.05+/-0.24 liters (95% CI -0.06 to +1.61), p=0.35, giving a mean percentage change of 3.18%+/-11.66 (95% CI -2.26 to 8.62). Previously held concerns about worsening pulmonary function through the short-term use of beta-blockers should not dissuade their perioperative usage in patients with peripheral vascular disease. Furthermore, the accuracy of pulmonary function tests in preoperative assessment and risk stratification also appears unaffected by this therapy.

This study aims to explore the effects of tranexamic acid on the coagulation indexes of patients undergoing heart valve replacement surgery under the condition of cardiopulmonary bypass (CPB). One hundred patients who conformed to the inclusive criteria were selected and divided into a tranexamic acid group and a non-tranexamic acid group. They all underwent heart valve replacement surgery under CPB. Patients in the tranexamic acid group were intravenously injected with 1 g of tranexamic acid (100 mL) at the time point after anesthesia induction and before skin incision and at the time point after the neutralization of heparin. Patients in the non-tranexamic acid group were given 100 mL of normal saline at corresponding time points, respectively. Then the coagulation indexes of the two groups were analyzed. The activated blood clotting time (ACT) of the two groups was within normal scope before CPB, while four coagulation indexes including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), and fibrinogen (FIB) had significant increases after surgery; the PT and INR of the tranexamic acid group had a remarkable decline after surgery. All the findings suggest that the application of tranexamic acid in heart valve replacement surgery under CPB can effectively reduce intraoperative and postoperative blood loss. PMID:27694613

Management of postoperative pain is a common problem in endoscopic sinus surgery. The objective of this study is the evaluation of pregabalin and acetaminophen effects on the management of postoperative pain in patients with nasal polyposis undergoing functional endoscopic sinus surgery (FESS). In this clinical trial, double-blinded study, 70 patients with nasal polyposis who have indication of FESS were enrolled to this study. After operation, patients were divided randomly into pregabalin and acetaminophen therapy groups. The pregabalin group (n = 35) was treated under pregabalin 50 mg TDS and the acetaminophen group (n = 35) was treated under tablet acetaminophen 500 mg/6 h. Each group was administered for 3 d. The visual analogue scale (VAS) was measured in onset, 12, 24, 48 and 72 h after surgery. All data were entered into SPSS software (SPSS Inc., Chicago, IL) and appropriate statistical tests were assessed to every relation. In this study, there was no significant difference between two groups according to VAS in onset (p = .37); however, VAS in 12, 24, 48 and 72 h after operation was significantly lower in the pregabalin group compared with the acetaminophen group (p < .0001, for every four). Also in the pregabalin group, adverse effects were significantly lower than the acetaminophen group (p < .03). Pregabalin has more effect, safely and usefully than acetaminophen on the management of postoperative pain in the patients with nasal polyposis undergoing functional endoscopic sinus surgery.

Extremely obese adolescents are increasingly undergoing bariatric procedures, which restrict dietary intake. However, as yet, no data are available describing the change in caloric density or composition of the adolescent bariatric patient's diet pre- and postoperatively. Our objective was to assess the 1-year change in the dietary composition of adolescents undergoing bariatric surgery at a tertiary care children's hospital. A total of 27 subjects (67% female, 77% white, age 16.7 ± 1.4 yr, baseline body mass index 60.1 ± 14.1 kg/m(2)) were prospectively enrolled into an observational cohort study 1 month before undergoing laparoscopic Roux-en-Y gastric bypass from August 2005 to March 2008. The 3-day dietary intake was recorded at baseline (n = 24) and 2 weeks (n = 16), 3 months (n = 11), and 1 year (n = 9) postoperatively. The dietary record data were verified by structured interview and compared with the Dietary Reference Intake values for ages 14-18 years. By 1 year after surgery, the mean caloric intake, adjusted for body mass index was 1015 ± 182 kcal/d, a 35% reduction from baseline. The proportion of fat, protein, and carbohydrate intake did not differ from baseline. However, the protein intake was lower than recommended postoperatively. The calcium and fiber intake was also persistently lower than recommended. Calcium and vitamin B(12) supplementation increased the likelihood of meeting the daily minimal recommendations (P ≤ .02). At 1 year after Roux-en-Y gastric bypass, the adolescents' caloric intake remained restricted, with satisfactory macronutrient composition but a lower than desirable intake of calcium, fiber, and protein.

Cardiac surgery is accompanied by an increase of oxidative stress, a significantly reduced antioxidant (AOX) capacity, postoperative inflammation, all of which may promote the development of organ dysfunction and an increase in mortality. Selenium is an essential co-factor of various antioxidant enzymes. We hypothesized a less pronounced decrease of circulating selenium levels in patients undergoing off-pump coronary artery bypass (OPCAB) surgery due to less intraoperative oxidative stress. In this prospective randomised, interventional trial, 40 patients scheduled for elective coronary artery bypass grafting were randomly assigned to undergo either on-pump or OPCAB-surgery, if both techniques were feasible for the single patient. Clinical data, myocardial damage assessed by myocard specific creatine kinase isoenzyme (CK-MB), circulating whole blood levels of selenium, oxidative stress assessed by asymmetric dimethylarginine (ADMA) levels, antioxidant capacity determined by glutathionperoxidase (GPx) levels and perioperative inflammation represented by interleukin-6 (IL-6) levels were measured at predefined perioperative time points. At end of surgery, both groups showed a comparable decrease of circulating selenium concentrations. Likewise, levels of oxidative stress and IL-6 were comparable in both groups. Selenium levels correlated with antioxidant capacity (GPx: r = 0.720; p<0.001) and showed a negative correlation to myocardial damage (CK-MB: r =  -0.571, p<0.001). Low postoperative selenium levels had a high predictive value for the occurrence of any postoperative complication. OPCAB surgery is not associated with less oxidative stress and a better preservation of the circulating selenium pool than on-pump surgery. Low postoperative selenium levels are predictive for the development of complications. ClinicalTrials.gov NCT01409057.

Objective After radiation failure for early T-stage larynx cancer, national guidelines recommend salvage surgery. Total laryngectomy and conservation laryngeal surgery with an open or endoscopic approach are both used. Beyond single-institution studies, there is a lack of evidence concerning the outcomes of these procedures. We aim to study whether treatment with conservation laryngeal surgery is associated with poorer outcomes than treatment with total laryngectomy as salvage surgery after radiation failure for T1/T2 larynx cancers. Study Design A retrospective study was conducted of adult squamous cell larynx cancer cases in the National Cancer Database diagnosed from 2004 to 2012. Setting Commission on Cancer cancer programs in the United States. Methods Demographic, facility, tumor, and survival variables were included in the analyses. Multivariate survival regressions as well as univariate Kaplan-Meier analyses were conducted. Results Slightly more than 7% of patients receiving radiotherapy for T1/T2 larynx cancers later received salvage surgery. Salvage with partial laryngectomy was not associated with diminished survival as compared with total laryngectomy. However, positive surgical margins were associated with worse outcomes (hazard ratio, 1.782; P = .001), and a larger percentage of patients receiving partial laryngectomy had positive margins than those receiving total laryngectomy. Facility characteristics were not associated with differences in salvage surgery type or outcomes. Conclusion In recognition of the inherent selection bias, patients who experienced recurrences after radiation for T1/T2 larynx cancer and underwent conservation salvage laryngeal surgery demonstrated clinical outcomes similar to those of patients undergoing salvage total laryngectomy. Increased rates of positive surgical margins were observed among patients undergoing salvage conservation surgery.

Retrospective study of prospectively collected data. To determine if postoperative morbidity for patients undergoing spinal deformity surgery varies by sex. Influence of sex has been investigated in other surgical procedures but has not yet been studied in adult spinal deformity surgery. The American College of Surgeons National Surgical Quality Improvement Program is a large multicenter clinical registry that prospectively collects preoperative risk factors, intraoperative variables, and 30-day postoperative morbidity and mortality outcomes from about 400 hospitals nationwide. Current Procedural Terminology codes were used to query the database for adults who underwent fusion for spinal deformity. Patients were separated into groups of male and female sex. Univariate analysis and multivariate logistic regression were used to analyze the effect of sex on the incidence of postoperative morbidity and mortality. Female sex was found to be a predictor of any complication[odds ratio (OR): 1.4, 95% confidence interval (CI) 1.2-1.7, P < 0.0001], intra- or postoperative RBC transfusion (OR: 1.6, 95% CI 1.4-1.9, P < .0001), urinary tract infection (OR: 2.0, 95% CI 1.2-3.3, P = 0.0046), and length of stay >5 days (OR: 1.3, 95% CI 1.1-1.5, P = 0.0015). Male sex was associated with higher rate of pulmonary (2.9% vs. 2.0%, P = 0.0344) and cardiac complications (0.9% vs. 0.5%, P = 0.0497). However, male sex as an independent risk factor for pulmonary (OR: 1.4, 95% CI 1.0-2.1, P = 0.0715) and cardiac complications (OR: 1.9, 95% CI 0.9-4.0, P = 0.1076) did not reach significance. Female sex was found to increase overall morbidity, particularly for urinary tract infection, transfusion, and length of stay >5 days. Male sex was associated with greater incidence of pulmonary and cardiac complications. Thus, sex and other patient characteristics highlighted must be considered as part of surgical risk planning and patient counseling. 3.

Increased red cell distribution width (RDW) is associated with poorer outcomes in various patient populations. We investigated the association between preoperative RDW and anaemia on 30-day postoperative mortality among elderly patients undergoing non-cardiac surgery. Medical records of 24,579 patients aged 65 and older who underwent surgery under anaesthesia between 1 January 2012 and 31 October 2016 were retrospectively analysed. Patients who died within 30 days had higher median RDW (15.0%) than those who were alive (13.4%). Based on multivariate logistic regression, in our cohort of elderly patients undergoing non-cardiac surgery, moderate/severe preoperative anaemia (aOR 1.61, p = 0.04) and high preoperative RDW levels in the 3rd quartile (>13.4% and ≤14.3%) and 4th quartile (>14.3%) were significantly associated with increased odds of 30-day mortality - (aOR 2.12, p = 0.02) and (aOR 2.85, p = 0.001) respectively, after adjusting for the effects of transfusion, surgical severity, priority of surgery, and comorbidities. Patients with high RDW, defined as >15.7% (90th centile), and preoperative anaemia have higher odds of 30-day mortality compared to patients with anaemia and normal RDW. Thus, preoperative RDW independently increases risk of 30-day postoperative mortality, and future risk stratification strategies should include RDW as a factor.

ε-Aminocaproic acid (EACA) and tranexamic acid (TXA) are used for antifibrinolytic therapy in neonates undergoing cardiac surgery, although data directly comparing their blood-sparing efficacy are not yet available. We compared two consecutive cohorts of neonates for the effect of these two medications on perioperative blood loss and allogeneic transfusions. Data from the EACA group (n = 77) were collected over a 12-month period; data from the tranexamic acid group (n = 28) were collected over a 5-month period. Blood loss, rate of reoperation due to bleeding, and transfusion requirements were measured. There was no significant difference in blood loss at 6 hours (EACA 24 [17-30] mL/kg [median (interquartile range)] vs. TXA 20 [11-34] mL/kg, P = 0.491), at 12 hours (EACA 31 [22-38] mL/kg vs. TXA 27 [19-43] ml/kg, P = 0.496) or at 24 hours postoperatively (EACA 41 [31-47] mL/kg vs. TXA 39 [27-60] mL/kg; P = 0.625) or transfusion of blood products. ε-Aminocaproic acid and tranexamic acid are equally effective with respect to perioperative blood loss and transfusion requirements in newborns undergoing cardiac surgery. © Georg Thieme Verlag KG Stuttgart · New York.

Among the various pharmacological options to decrease peri-operative bleeding, tranexamic acid appears to be one of the most interesting. Several trials have consistently documented the efficacy of this synthetic drug in reducing the risk of blood loss and the need for allogeneic blood transfusion in patients undergoing total hip and knee arthroplasty. The safety of intravenous tranexamic acid in major orthopaedic surgery, particularly regarding the risk of venous thromboembolism, was systematically analysed in this review. A systematic search of the literature identified 73 randomised controlled trials involving 4,174 patients and 2,779 controls. The raw overall incidence of venous thromboembolism was 2.1% in patients who received intravenous tranexamic acid and 2.0% in controls. A meta-analytic pooling showed that the risk of venous thromboembolism in tranexamic acid-treated patients was not significantly different from that of controls (risk difference: 0.01%, 95% confidence interval [CI]: −0.05%, 0.07%; risk ratio: 1.067, 95% CI: 0.760–1.496). Other severe drug-related adverse events occurred very rarely (0.1%). In conclusion, the results of this systematic review and meta-analysis show that intravenous tranexamic acid is a safe pharmacological treatment to reduce blood loss and transfusion requirements in patients undergoing major orthopaedic surgery.

The aim of this systematic review and meta-analysis was to evaluate the risk of surgical infection, alveolar osteitis, and adverse effects using systemic metronidazole in comparison with placebo in healthy patients undergoing third molar surgery. The eligible reports were identified from diverse science sources. Clinical trials meeting the inclusion and exclusion criteria and an acceptable Oxford Quality Score were included in this study. The evaluation of risk was done using the Risk Reduction Calculator and Review Manager 5.3., from the Cochrane Library. A significant risk reduction was assumed when the upper limit of the 95% confidence intervals was <1 and the lower limit did not cross zero (negative number) alongside a p value of <0.05 for the overall test. Data of 667 patients from five clinical trials were used for the assessment of risk. Our analysis showed no reduction of the risk of infection or dry socket in patients receiving metronidazole compared to whom took placebo. Meanwhile, the adverse effects did not exhibit a difference between the studied groups. The routine use of systemic metronidazole to prevent surgical site infection and/or dry socket in healthy patients undergoing third molar surgery is not recommended.

Clindamycin was given intravenously to 15 patients undergoing colorectal surgery in an initial dose of 600 mg, given at induction of anesthesia followed by 6 doses of 600 mg at 8-h intervals. Series of serum samples and fecal specimens were taken for analysis of clindamycin concentrations. Tissue samples from the gut wall were taken at surgery. The highest serum concentrations observed occurred 30 min after administration of clindamycin and varied between 6.8 and 37.9 microgram/ml (mean, 14.8 +/- 2.0 [standard error] microgram/ml). The clindamycin concentrations in the tissue samples were between 1.8 and 13.0 microgram/g. Clindamycin concentration in the fecal samples varied between 2.1 and 460 microgram/g. Fecal samples were also collected during the investigation period for cultivation of aerobic and anaerobic bacteria. Among the aerobic bacteria, enterococci and streptococci decreased during the prophylaxis period. Anaerobic bacteria also decreased significantly during the same period. After the clindamycin administration period, enterococci, streptococci and anaerobic bacteria proliferated. No anaerobic strains resistant to clindamycin were isolated. Postoperative infections due to Streptococcus faecalis and different enterobacteria such as Escherichia coli, Enterobacter cloacae, Citrobacter freundii, and Klebsiella occurred in five patients.

Brain natriuretic peptide (BNP) levels correlate with prognosis in patients with cardiac disease and may be useful in the risk stratification of cardiac patients undergoing noncardiac surgery (NCS). The objective of this study was to examine whether BNP levels predict perioperative events in cardiac patients undergoing NCS. Patients undergoing NCS with at least 1 of the following criteria were included: a clinical history of congestive heart failure (CHF), ejection fraction <40%, or severe aortic stenosis. All patients underwent echocardiography and measurement of BNP performed using the ADVIA-Centaur BNP assay (Bayer HealthCare). Clinical endpoints were death, myocardial infarction or pulmonary congestion requiring intravenous diuretics at 30 days of follow-up. Forty-four patients were entered into the study; 15 patients (34%) developed cardiac postoperative complications. The mean BNP level was 1,366 +/- 1,420 pg/ml in patients with events and 167 +/- 194 pg/ml in patients without events, indicating a highly significant difference (p < 0.001). The ROC area under the curve was 0.91 (95% CI 0.83-0.99) with an optimal cutoff of >165 pg/ml (100% sensitivity, 70% specificity). BNP levels may predict perioperative complications in cardiac patients undergoing NCS, and the measurement of BNP should be considered to assess the preoperative cardiac risk. (c) 2007 S.

Reoperation and readmission are often avoidable, costly, and difficult to predict. We sought to identify risk factors for readmission and reoperation after spine surgery and to use these factors to develop a scoring system predictive of readmission and reoperation. The National Surgical Quality Improvement Project database for years 2012 to 2014 was reviewed for patients undergoing spinal surgery, and 68 perioperative characteristics were analyzed. A total of 111,892 patients who underwent spinal surgery were identified. The rate of reoperation was 3.1%, the rate of readmission was 5.2%, and the occurrence of either was 6.6%. Multivariate analysis found 20 perioperative factors significantly associated with both readmission and reoperation. Preoperative and operative factors found significant included age >60 years, African-American race, recent weight loss, chronic steroid use, on dialysis, blood transfusion required, American Society of Anesthesiologists classification ≥3, contaminated wound, >10% probability of experiencing morbidity, and operative time >3 hours. Postoperative associations identified included urinary tract infection, stroke, dehiscence, pulmonary embolism, sepsis, septic shock, deep and superficial surgical site infection, reintubation, and failure to wean from ventilator. An unweighted and weighted risk score were generated that yielded receiver operating characteristic curves with areas under the curve of 0.707 (95% confidence interval [CI]: 0.701-0.713) and 0.743 (95% CI: 0.736-0.749) 0.708 (95% CI: 0.702-0.715), respectively. Patients with an unweighted score ≥7 had a more than 20-fold increased risk of reoperation or readmission and a more than 1000-fold increased risk of mortality than did patients with a score of 0.

Objective To measure the concentration of cefazolin in the anterior mediastinal adipose tissue of patients undergoing cardiac surgery, determining the variation of cefazolin concentration. Methods Two samples of approximately 1g of subcutaneous tissue were collected from 19 patients who underwent surgery in December 2015: the first sample was collected right after sternotomy and the second one, before sternal synthesis with steel wires. Antibiotic dosage was administered through high performance liquid chromatography. Results We observed a positive and statistically significant correlation between time 1 and cefazolin concentration (r=0.489 and P=0.039). For time 2 and cefazolin concentration, there was a negative and statistically significant correlation between both variables (r=-0.793 and P<0.001). A negative correlation was also observed between body mass index and cefazolin concentration at time 2 (r=-0.510 and P=0.031). The regression model showed that every 1-minute increase in time 1 corresponded to an increase of 0.240 µg/dL in cefazolin concentration, whereas every 1-minute increase in time 2 corresponded to a reduction of 0.046 µg/dL in cefazolin concentration. As for body mass index, every 1 kg/m2 increase corresponded to a reduction of about 0.510 µg/dL in cefazolin concentration. Conclusion There was a positive and significant correlation between the initial time of surgery and cefazolin level in the first dosage. The evaluation of the second dosage showed a negative and significant correlation between cefazolin level and the second time of dosage. The concentration of cefazolin is under the influence of body mass index. PMID:28977194

Adults with CHD often exhibit complex cardiac abnormalities, whose management requires specific clinical and surgical expertise. To enable easier access of these patients to highly specialised care, we implemented a collaborative programme that incorporates medical and surgical specialists belonging to both paediatric and adult cardiovascular institutions. The objective of this study was to review the experience gained and to analyse the surgical outcome of major cardiac surgery. We retrospectively reviewed all consecutive patients admitted for major cardiac surgery using our network between January, 2010 and December, 2013. Analysis of surgical outcome was performed in patients selected for major cardiac surgery with cardiopulmonary bypass. Early and late outcomes were evaluated. Out of a total of 433 inward patients, 86 were selected for surgery. The median age was 25.5 years, -64 patients (74.4%) had previously undergone heart surgery, and -55 patients (64%) had been subjected to at least one sternotomy. Abnormalities of the left ventricular and right ventricular outflow tract were the most frequent (37.2% and 30.2%, respectively), and despite high-surgical complexity only one death occurred (in-hospital mortality 1.1%). On a median follow-up time of 4 years no deaths and no heart-failure events have occurred; one patient underwent further cardiac surgery programmed at the time of discharge. Low mortality and morbidity rates can be obtained in high-surgical complexity adults with CHD populations when paediatric and adult cardiac specialists operate in the same multidisciplinary environment.

Glaucoma drainage device surgery in children and adults: a comparative study of outcomes and complications.

To compare the postoperative outcomes and complications of glaucoma drainage device (GDD) surgery in pediatric (<18 years old) and adult patients. Retrospective, comparative study including all patients who underwent Baervedlt or Molteno device surgery by the same surgeon. Success criteria included postoperative intraocular pressure (IOP) between 6 and 21 mmHg and a 20% reduction from baseline. Fifty-two children (69 eyes) and 130 adults (145 eyes) were included. Mean IOP and number of medications were significantly reduced postoperatively in both groups. Overall failure rate was similar in children and adults. However, GDD failed earlier in adults than in children. Hypotony was the most common complication in both groups in the first 6 months postoperatively. Later on, bleb encapsulation was more frequent in children, while corneal decompensation tended to be more frequent and occurred earlier in adults. Children also had a higher rate of infectious endophthalmitis and required tube repositioning more frequently than adults. GDD surgery presents different postoperative challenges in children and adults, and the surgeon should remain vigilant for complications throughout the postoperative period, especially for signs of endophthalmitis or bleb encapsulation in pediatric patients. On the other hand, adults may be more prone to early corneal decompensation.

Third-space fluid shift, the movement of body fluid to a non-functional space, is a frequently occurring and potentially fatal clinical phenomenon. Little published research exists however in medical or nursing journals concerning its incidence, significance and ramifications in elderly patients undergoing major gastrointestinal surgery. This initial article, part I, explores fluid movement between fluid compartments and uses these principles to discuss the pathophysiology of the two distinct phases of third-space fluid shift. Part II will examine the criteria nurses could use in the clinical assessment of patients in both first and second phases third-space fluid shift and discuss the clinical reliability of these criteria.

Acute kidney injury (AKI) is a common and serious complication for pediatric cardiac surgery patients associated with increased morbidity, mortality, and length of stay. Current strategies focus on risk reduction and early identification because there are no known preventive or therapeutic agents. Cardiac surgery and cardiopulmonary bypass lyse erythrocytes, releasing free hemoglobin and contributing to oxidative injury. Acetaminophen may prevent AKI by reducing the oxidation state of free hemoglobin. To test the hypothesis that early postoperative acetaminophen exposure is associated with reduced risk of AKI in pediatric patients undergoing cardiac surgery. In this retrospective cohort study, the setting was 2 tertiary referral children's hospitals. The primary and validation cohorts included children older than 28 days admitted for cardiac surgery between July 1, 2008, and June 1, 2016. Exclusion criteria were postoperative extracorporeal membrane oxygenation and inadequate serum creatinine measurements to determine AKI status. Acetaminophen exposure in the first 48 postoperative hours. Acute kidney injury based on Kidney Disease: Improving Global Outcomes serum creatinine criteria (increase by ≥0.3 mg/dL from baseline or at least 1.5-fold more than the baseline [to convert to micromoles per liter, multiply by 88.4]) in the first postoperative week. The primary cohort (n = 666) had a median age of 6.5 (interquartile range [IQR], 3.9-44.7) months, and 341 (51.2%) had AKI. In unadjusted analyses, those with AKI had lower median acetaminophen doses than those without AKI (47 [IQR, 16-88] vs 78 [IQR, 43-104] mg/kg, P < .001). In logistic regression analysis adjusting for age, cardiopulmonary bypass time, red blood cell distribution width, postoperative hypotension, nephrotoxin exposure, and Risk Adjustment for Congenital Heart Surgery score, acetaminophen exposure was protective against postoperative AKI (odds ratio, 0.86 [95% CI, 0.82-0.90] per each

To determine the cost-effectiveness of gastric band surgery in overweight but not obese people who receive standard diabetes care. A microsimulation model (United Kingdom Prospective Diabetes Study outcomes model) was used to project diabetes outcomes and costs from a two-year Australian randomized trial of gastric band (GB) surgery in overweight but not obese people (BMI 25 to 30kg/m 2 ) on to a comparable population of U.S. adults from the National Health and Nutrition Examination Survey (N=254). Estimates of cost-effectiveness were calculated based on the incremental cost-effectiveness ratios (ICERs) for different treatment scenarios. Costs were inflated to 2015 U.S. dollar values and an ICER of less than $50,000 per QALY gained was considered cost-effective. The incremental cost-effectiveness ratio for GB surgery at two years exceeded $90,000 per quality-adjusted life year gained but decreased to $52,000, $29,000 and $22,000 when the health benefits of surgery were assumed to endure for 5, 10 and 15 years respectively. The cost-effectiveness of GB surgery was sensitive to utility gained from weight loss and, to a lesser degree, the costs of GB surgery. However, the cost-effectiveness of GB surgery was affected minimally by improvements in HbA1c, systolic blood pressure and cholesterol. GB surgery for overweight but not obese people with T2D appears to be cost-effective in the U.S. setting if weight loss endures for more than five years. Health utility gained from weight loss is a critical input to cost-effectiveness estimates and therefore should be routinely measured in populations undergoing bariatric surgery.

Objective To determine the value of apparent diffusion coefficient (ADC) histogram parameters for the prediction of individual survival in patients undergoing surgery for recurrent glioblastoma (GBM) in a retrospective cohort study. Methods Thirty-one patients who underwent surgery for first recurrence of a known GBM between 2008 and 2012 were included. The following parameters were collected: age, sex, enhancing tumor size, mean ADC, median ADC, ADC skewness, ADC kurtosis and fifth percentile of the ADC histogram, initial progression free survival (PFS), extent of second resection and further adjuvant treatment. The association of these parameters with survival and PFS after second surgery was analyzed using log-rank test and Cox regression. Results Using log-rank test, ADC histogram skewness of the enhancing tumor was significantly associated with both survival (p = 0.001) and PFS after second surgery (p = 0.005). Further parameters associated with prolonged survival after second surgery were: gross total resection at second surgery (p = 0.026), tumor size (0.040) and third surgery (p = 0.003). In the multivariate Cox analysis, ADC histogram skewness was shown to be an independent prognostic factor for survival after second surgery. Conclusion ADC histogram skewness of the enhancing lesion, enhancing lesion size, third surgery, as well as gross total resection have been shown to be associated with survival following the second surgery. ADC histogram skewness was an independent prognostic factor for survival in the multivariate analysis.

The use of neuromuscular blocking agent (NMBA) during anesthesia may interfere with facial nerve monitoring (FNM) during parotid surgery. Sugammadex has been reported to be an effective and safe reversal of rocuronium-induced neuromuscular block (NMB) during surgery. This study investigated the feasibility and clinical effectiveness of sugammadex for NMB reversal during FNM in Parotid surgery. Fifty patients undergoing parotid surgery were randomized allocated into conventional anesthesia group (Group C, n = 25) and sugammadex group (Group S, n = 25). Group C did not receive any NMBA. Group S received rocuronium 0.6 mg/kg at anesthesia induction and sugammadex 2 mg/kg at skin incision. The intubating condition and influence on FNM evoked EMG results were compared between groups. The intubation condition showed significantly better in group S patients than C group patients (excellent in 96% v.s. 24%). In group S, rapid reverse of NMB was found and the twitch (%) recovered from 0 to >90% within 10 min. Positive and high EMG signals were obtained in all patients at the time point of initial facial nerve stimulation in both groups. There was no significant difference as comparing the EMG amplitudes detected at the time point of initial and final facial nerve stimulation in both groups. Implementation of sugammadex in anesthesia protocol is feasible and reliable for successful FNM during parotid surgery. Copyright © 2017. Published by Elsevier Taiwan.

There are limited prospective, controlled data evaluating survival in patients receiving early surgery vs medical therapy for prosthetic valve endocarditis (PVE). To determine the in-hospital and 1-year mortality in patients with PVE who undergo valve replacement during index hospitalization compared with patients who receive medical therapy alone, after controlling for survival and treatment selection bias. Participants were enrolled between June 2000 and December 2006 in the International Collaboration on Endocarditis-Prospective Cohort Study (ICE-PCS), a prospective, multinational, observational cohort of patients with infective endocarditis. Patients hospitalized with definite right- or left-sided PVE were included in the analysis. We evaluated the effect of treatment assignment on mortality, after adjusting for biases using a Cox proportional hazards model that included inverse probability of treatment weighting and surgery as a time-dependent covariate. The cohort was stratified by probability (propensity) for surgery, and outcomes were compared between the treatment groups within each stratum. Valve replacement during index hospitalization (early surgery) vs medical therapy. In-hospital and 1-year mortality. Of the 1025 patients with PVE, 490 patients (47.8%) underwent early surgery and 535 individuals (52.2%) received medical therapy alone. Compared with medical therapy, early surgery was associated with lower in-hospital mortality in the unadjusted analysis and after controlling for treatment selection bias (in-hospital mortality: hazard ratio [HR], 0.44 [95% CI, 0.38-0.52] and lower 1-year mortality: HR, 0.57 [95% CI, 0.49-0.67]). The lower mortality associated with surgery did not persist after adjustment for survivor bias (in-hospital mortality: HR, 0.90 [95% CI, 0.76-1.07] and 1-year mortality: HR, 1.04 [95% CI, 0.89-1.23]). Subgroup analysis indicated a lower in-hospital mortality with early surgery in the highest surgical propensity quintile (21

The present study aimed to compare the utility of various inflammatory marker- and nutritional status-based prognostic factors, including many previous established prognostic factors, for predicting the prognosis of stage IV gastric cancer patients undergoing non-curative surgery. A total of 33 patients with stage IV gastric cancer who had undergone palliative gastrectomy and gastrojejunostomy were included in the study. Univariate and multivariate analyses were performed to evaluate the relationships between the mGPS, PNI, NLR, PLR, the CONUT, various clinicopathological factors and cancer-specific survival (CS). Among patients who received non-curative surgery, univariate analysis of CS identified the following significant risk factors: chemotherapy, mGPS and NLR, and multivariate analysis revealed that the mGPS was independently associated with CS. The mGPS was a more useful prognostic factor than the PNI, NLR, PLR and CONUT in patients undergoing non-curative surgery for stage IV gastric cancer.

Left atrial pressure and its surrogate, pulmonary capillary wedge pressure (PCWP), are important for determining diastolic function. The role of transthoracic echocardiography (TTE) in assessing diastolic function is well established in awake subjects. The objective was to assess the accuracy of predicting PCWP by TTE and transesophageal echocardiography (TEE) during coronary artery surgery. In 27 adult patients undergoing on-pump coronary artery surgery, simultaneous echocardiographic and hemodynamic measurements were obtained immediately before anesthesia (TTE), after anesthesia and mechanical ventilation (TTE and TEE), during conduit harvest (TEE), and after separation from cardiopulmonary bypass (TEE). Twenty patients had an ejection fraction (EF) of 0.5 or greater. With the exception of E/e' and S/D ratios, echocardiographic values changed over the echocardiographic studies. In patients with low EF, E velocity, deceleration time, pulmonary vein D, S/D, and E/e' ratios correlated well with PCWP before anesthesia. After induction of anesthesia using TTE or TEE, correlations were poor. In normal EF patients, correlations were poor for both TEE and TTE at all five stages. The sensitivity and specificity of echocardiographic values were not high enough to predict raised PCWP except for a fixed curve pattern of interatrial septum (area under the curve 0.89 for PCWP ≥ 17, and 0.98 for ≥ 18 mmHg) and S/D less than 1 (area under the curve 0.74 for PCWP ≥ 17, and 0.78 for ≥ 18 mmHg). Doppler assessment of PCWP was neither sensitive nor specific enough to be clinically useful in anesthetized patients with mechanical ventilation. The fixed curve pattern of the interatrial septum was the best predictor of raised PCWP.

Introduction: Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery. Materials and Methods: A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1–10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively. Results: In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation. Conclusion: Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

Fatty acid binding protein (FABP) is an intracellular transport protein associated with myocardial damage size in patients undergoing cardiac surgery. Furthermore, elevated FABP serum concentrations are related to a number of common comorbidities, such as heart failure, chronic kidney disease, diabetes mellitus, and metabolic syndrome, which represent important risk factors for postoperative acute kidney injury (AKI). Data are lacking on the association between preoperative FABP serum level and postoperative incidence of AKI. This prospective cohort study investigated the association between preoperative h-FABP serum concentrations and postoperative incidence of AKI, hospitalization time and length of ICU treatment. Blood samples were collected according to a predefined schedule. The AKI Network definition of AKI was used as primary endpoint. All associations were analysed using descriptive and univariate analyses. Between 05/2009 and 09/2009, 70 patients undergoing cardiac surgery were investigated. AKI was observed in 45 patients (64%). Preoperative median (IQR) h-FABP differed between the AKI group (2.9 [1.7-4.1] ng/ml) and patients without AKI (1.7 [1.1-3.3] ng/ml; p = 0.04), respectively. Patients with AKI were significantly older. No statistically significant differences were found for gender, type of surgery, operation duration, CPB-, or X-Clamp time, preoperative cardiac enzymes, HbA1c, or CRP between the two groups. Preoperative h-FABP was also correlated with the length of ICU stay (rs = 0.32, p = 0.007). We found a correlation between preoperative serum h-FABP and the postoperative incidence of AKI. Our results suggest a potential role for h-FABP as a biomarker for AKI in cardiac surgery.

The aim is to investigate ethnic variation, in presentation and biometric parameters, within the population undergoing cataract surgery in Auckland. The design is a retrospective study. Four thousand nine hundred thirty-one eyes of 3524 consecutive patients undergoing cataract surgery in Auckland Public Hospital over 18 months were included in the study. Analysis of preoperative medical records was performed. Age, gender, self-reported ethnicity, keratometry, anterior chamber depth, axial length and intraocular lens (IOL) power data were collected. Māori (4.7%) were under-represented compared with the proportion of Māori attending the eye clinic (5.5%) and in the major patient catchment area (8.2%). People of Māori, Pacific and Indian ethnicities presented at a significantly younger age (66.4, 65.9 and 67.9 years, respectively) than those of Caucasian and Asian ethnicities (76.4 and 71.3 years, respectively, P < 0.001). Advanced cataract was more likely in Pacific peoples and Māori than Caucasians. The mean axial length was longest in Asian eyes (23.83 ± 1.52 mm). The mean anterior chamber depth in the eyes of Pacific peoples (3.20 ± 0.39 mm) was significantly greater than that of Caucasians (3.09 ± 0.42 mm, P = 0.001) and Asians (3.05 ± 0.49 mm, P < 0.001). The mean IOL power in Asian eyes was 19.45D. This was significantly lower than the IOL power required by Caucasian (20.72D, P < 0.001) and Pacific ethnicities (20.61D, P = 0.001). With-the-rule astigmatism was highly prevalent in Māori and Pacific peoples, whereas in all other ethnicities, against-the-rule astigmatism was more common. This study identified significant ethnic variation in presentation for cataract surgery and ocular biometric parameters. These data may help identify potential biometric refinements and those at risk of developing ocular morbidities known to be associated with these parameters. © 2015 Royal Australian and New Zealand

There is a paucity of literature describing the association of age with the risk of adverse events following bariatric surgery. The purpose of this study is to investigate the association of age with 30-day morbidity and mortality following laparoscopic bariatric surgery using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. All adult patients undergoing laparoscopic Roux-en-Y gastric bypass (RNGYB) or sleeve gastrectomy (SG) were identified within the MBSAQIP database. Patients were divided into five equal age quintiles. Binary outcomes of interest, including cardiac, pulmonary, wound, septic, clotting, and renal events, in addition to the incidence of related 30-day unplanned reintervention, related 30-day mortality, and a composite morbidity and mortality outcome were compared across the age quintiles and procedures. A total of 266,544 patients met inclusion criteria. Older age was associated with an increased risk of all morbidity outcomes except venous thromboembolism events, 30-day mortality, and the composite morbidity and mortality outcome. Patients who underwent Roux-en-Y gastric bypass had worse outcomes per quintile for almost every outcome of interest when compared to patients who underwent sleeve gastrectomy. Older patients and patients who undergo Roux-en-Y gastric bypass are at an increased risk of perioperative morbidity and mortality following laparoscopic bariatric surgery. Additional studies are needed to determine the association of age with long-term weight loss and cardiometabolic comorbidity resolution following bariatric surgery in order to determine if the increased perioperative risk is offset by improved long-term outcomes in older patients undergoing bariatric surgery.

The outcomes of emergent noncardiac, nonintracranial surgery in patients with previous stroke remain unknown. All emergency surgeries performed in Denmark (2005 to 2011) were analyzed according to time elapsed between previous ischemic stroke and surgery. The risks of 30-day mortality and major adverse cardiovascular events were estimated as odds ratios (ORs) and 95% CIs using adjusted logistic regression models in a priori defined groups (reference was no previous stroke). In patients undergoing surgery immediately (within 1 to 3 days) or early after stroke (within 4 to 14 days), propensity-score matching was performed. Of 146,694 nonvascular surgeries (composing 98% of all emergency surgeries), 5.3% had previous stroke (mean age, 75 yr [SD = 13]; 53% women, 50% major orthopedic surgery). Antithrombotic treatment and atrial fibrillation were more frequent and general anesthesia less frequent in patients with previous stroke (all P < 0.001). Risks of major adverse cardiovascular events and mortality were high for patients with stroke less than 3 months (20.7 and 16.4% events; OR = 4.71 [95% CI, 4.18 to 5.32] and 1.65 [95% CI, 1.45 to 1.88]), and remained increased for stroke within 3 to 9 months (10.3 and 12.3%; OR = 1.93 [95% CI, 1.55 to 2.40] and 1.20 [95% CI, 0.98 to 1.47]) and stroke more than 9 months (8.8 and 11.7%; OR = 1.62 [95% CI, 1.43 to 1.84] and 1.20 [95% CI, 1.08 to 1.34]) compared with no previous stroke (2.3 and 4.8% events). Major adverse cardiovascular events were significantly lower in 323 patients undergoing immediate surgery (21%) compared with 323 successfully propensity-matched early surgery patients (29%; P = 0.029). Adverse cardiovascular outcomes and mortality were greatly increased among patients with recent stroke. However, events were higher 4 to 14 days after stroke compared with 1 to 3 days after stroke.

Cardiac surgery ICU characteristics and clinician staffing patterns have not been well characterized. We sought to describe Pennsylvania cardiac ICUs and to determine whether ICU characteristics are associated with mortality in the 30 days after cardiac surgery. From 2012 to 2013, we conducted a survey of cardiac surgery ICUs in Pennsylvania to assess ICU structure, care practices, and clinician staffing patterns. ICU data were linked to an administrative database of cardiac surgery patient discharges. We used logistic regression to measure the association between ICU variables and death in 30 days. Cardiac surgery ICUs in Pennsylvania. Patients having coronary artery bypass grafting and/or cardiac valve repair or replacement from 2009 to 2011. None. Of the 57 cardiac surgical ICUs in Pennsylvania, 43 (75.4%) responded to the facility survey. Rounds included respiratory therapists in 26 of 43 (60.5%) and pharmacists in 23 of 43 (53.5%). Eleven of 41 (26.8%) reported that at least 2/3 of their nurses had a bachelor's degree in nursing. Advanced practice providers were present in most of the ICUs (37/43; 86.0%) but residents (8/42; 18.6%) and fellows (7/43; 16.3%) were not. Daytime intensivists were present in 21 of 43 (48.8%) responding ICUs; eight of 43 (18.6%) had nighttime intensivists. Among 29,449 patients, there was no relationship between mortality and nurse ICU experience, presence of any intensivist, or absence of residents after risk adjustment. To exclude patients who may have undergone transcatheter aortic valve replacement, we conducted a subgroup analysis of patients undergoing only coronary artery bypass grafting, and results were similar. Pennsylvania cardiac surgery ICUs have variable structures, care practices, and clinician staffing, although none of these are statistically significantly associated with mortality in the 30 days following surgery after adjustment.

During open heart surgery, patients are connected to a heart-lung bypass machine that pumps blood around the body ("perfusion") while the heart is stopped. Typically the blood is cooled during this procedure ("hypothermia") and warmed to normal body temperature once the operation has been completed. The main rationale for "whole body cooling" is to protect organs such as the brain, kidneys, lungs, and heart from injury during bypass by reducing the body's metabolic rate and decreasing oxygen consumption. However, hypothermic perfusion also has disadvantages that can contribute toward an extended postoperative hospital stay. Research in adults and small randomized controlled trials in children suggest some benefits to keeping the blood at normal body temperature throughout surgery ("normothermia"). However, the two techniques have not been extensively compared in children. The Thermic-2 study will test the hypothesis that the whole body inflammatory response to the nonphysiological bypass and its detrimental effects on different organ functions may be attenuated by maintaining the body at 35°C-37°C (normothermic) rather than 28°C (hypothermic) during pediatric complex open heart surgery. This is a single-center, randomized controlled trial comparing the effectiveness and acceptability of normothermic versus hypothermic bypass in 141 children with congenital heart disease undergoing open heart surgery. Children having scheduled surgery to repair a heart defect not requiring deep hypothermic circulatory arrest represent the target study population. The co-primary clinical outcomes are duration of inotropic support, intubation time, and postoperative hospital stay. Secondary outcomes are in-hospital mortality and morbidity, blood loss and transfusion requirements, pre- and post-operative echocardiographic findings, routine blood gas and blood test results, renal function, cerebral function, regional oxygen saturation of blood in the cerebral cortex, assessment of

Post-operative management in gastrointestinal (GI) surgery is becoming well established with 'Enhanced Recovery After Surgery' protocols starting 24 hours prior to surgery with carbohydrate loading and early oral or enteral feeding given to patients the first day following surgery. However, whether or not nutritional intervention should be initiated earlier in the preoperative period remains unclear. Poor pre-operative nutritional status has been linked consistently to an increase in post-operative complications and poorer surgical outcome. To review the literature on preoperative nutritional support in patients undergoing gastrointestinal surgery (GI). The searches were initially run in March 2011 and subsequently updated in February 2012. Databases including all EBM Reviews (Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA and NHSEED) MEDLINE, EMBASE, AMED, British Nursing Index Archive using OvidSP were included and a search was run on each database separately after which duplicates were excluded. The inclusion criteria were randomised controlled trials that evaluated pre-operative nutritional support in GI surgical participants using a nutritional formula delivered by a parenteral, enteral or oral route. The primary outcomes included post-operative complications and length of hospital stay. Two observers screened the abstracts for inclusion in the review and performed data extraction. Bias was assessed for each of the included studies using the bias assessment tables in the Cochrane Software Review Manager (version 5.1, Cochrane Collaboration). The trials were analysed using risk ratios with Mantel-Haenszel in fixed effects methods displayed with heterogeneity. Meta-analyses were undertaken on trials evaluating immune enhancing (IE) nutrition, standard oral supplements, enteral and parenteral nutrition (PN) which were administered pre-operatively.Study characteristics were summarised in tables. Dichotomous and ratio data were entered into meta-analyses for

Xenon was shown to cause less hemodynamic instability and reduce vasopressor needs during off-pump coronary artery bypass (OPCAB) surgery when compared with conventionally used anesthetics. As xenon exerts its organ protective properties even in subanesthetic concentrations, we hypothesized that in patients undergoing OPCAB surgery, 30% xenon added to general anesthesia with propofol results in superior hemodynamic stability when compared to anesthesia with propofol alone. Fifty patients undergoing elective OPCAB surgery were randomized to receive general anesthesia with 30% xenon adjuvant to a target-controlled infusion of propofol or with propofol alone. The primary end point was the total intraoperative dose of norepinephrine required to maintain an intraoperative mean arterial pressure >70 mm Hg. Secondary outcomes included the perioperative cardiorespiratory profile and the incidence of adverse and serious adverse events. Adding xenon to propofol anesthesia resulted in a significant reduction of norepinephrine required to attain the predefined hemodynamic goals (cumulative intraoperative dose: median [interquartile range]: 370 [116-570] vs 840 [335-1710] µg, P = .001). In the xenon-propofol group, significantly less propofol was required to obtain a similar depth of anesthesia as judged by clinical signs and the bispectral index (propofol effect site concentration [mean ± SD]: 1.8 ± 0.5 vs 2.8 ± 0.3 mg, P≤ .0001). Moreover, the xenon-propofol group required significantly less norepinephrine during the first 24 hours on the intensive care unit (median [interquartile range]: 1.5 [0.1-7] vs 5 [2-8] mg, P = .048). Other outcomes and safety parameters were similar in both groups. Thirty percent xenon added to propofol anesthesia improves hemodynamic stability by decreasing norepinephrine requirements in patients undergoing OPCAB surgery.

This study aims to explore the effects of tranexamic acid on the coagulation indexes of patients undergoing heart valve replacement surgery under the condition of cardiopulmonary bypass (CPB). One hundred patients who conformed to the inclusive criteria were selected and divided into a tranexamic acid group and a non-tranexamic acid group. They all underwent heart valve replacement surgery under CPB. Patients in the tranexamic acid group were intravenously injected with 1 g of tranexamic acid (100 mL) at the time point after anesthesia induction and before skin incision and at the time point after the neutralization of heparin. Patients in the non-tranexamic acid group were given 100 mL of normal saline at corresponding time points, respectively. Then the coagulation indexes of the two groups were analyzed. The activated blood clotting time (ACT) of the two groups was within normal scope before CPB, while four coagulation indexes including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), and fibrinogen (FIB) had significant increases after surgery; the PT and INR of the tranexamic acid group had a remarkable decline after surgery. All the findings suggest that the application of tranexamic acid in heart valve replacement surgery under CPB can effectively reduce intraoperative and postoperative blood loss. © The Author(s) 2016.

Bowel anastomosis performed during robot-assisted laparoscopic surgery in both adult and pediatric populations has typically been performed using endoscopic staplers or with exteriorization of the bowel. In the pediatric population, no articles have been published that explore the possibility of a completely intracorporeal hand-sewn anastomosis during robot-assisted laparoscopic surgery. We report our series of six children who were undergoing robot-assisted laparoscopic intracorporeal hand-sewn bowel anastomosis during bladder reconstructive surgery for neurogenic bladder. The postoperative course was uncomplicated with regard to the bowel anastomosis, demonstrating the feasibility of the technique in experienced hands.

Plavix (clopidogrel) is a potent antiplatelet agent used to prevent thrombosis in a variety of clinical settings. The perioperative management of thoracic surgery patients who are on clopidogrel at the time of surgery is not well defined. We conducted this review to examine the perioperative management and outcomes of patients undergoing general thoracic surgical procedures. From January 2005 to January 2010, 165 patients on clopidogrel underwent 182 operative procedures. Three management strategies were identified: Group I: clopidogrel continued through surgery (n = 17), Group II: clopidogrel discontinued with a bridging agent (n = 44) and Group III clopidogrel discontinued without a bridging agent (n = 121). Propensity score matched cohorts (17 clopidogrel continued; 34 clopidogrel discontinued) were constructed based on age, clopidogrel indication, American Society of Anesthesiology status, and procedure and used to compare the impact of clopidogrel management on postoperative bleeding and cardiovascular morbidity. Unmatched analysis revealed a significantly higher rate of transfusion in the group of patients who continued on clopidogrel throughout the perioperative period, compared with patients who had clopidogrel discontinued. Although there were more cardiovascular events in Groups II and III, there were no significant differences between groups in postoperative mortality, myocardial infarction, stroke, or reoperation for bleeding. In propensity matched patients only the rate of postoperative transfusions was significantly higher in patients continued on clopidogrel compared with patients whose clopidogrel was discontinued (35.3 vs. 2.9%), p < 0.004. In selected patients, some thoracic surgical procedures can be performed safely on clopidogrel but are associated with higher rates of postoperative transfusion.

The cytokine response to injury or trauma is of interest in terms of both its mediation of the acute phase response and its possible relation to the immunological depression observed after major surgery. In this study, the production of cytokines IL-1 beta, tumour necrosis factor-alpha (TNF-alpha), IL-6 and the naturally occurring inhibitor of IL-1, IL-1Ra, have been investigated in infants and children undergoing Swenson's pull-through operation for Hirschsprung's disease. Samples of peripheral blood were taken before, during and after surgery for the measurement of cytokines. IL-1Ra levels increased significantly (P < 0.01) at 2 h after commencement of surgery, with maximal levels for individual patients being attained between 3 h and 5 h (range 7.6-67.9 ng/ml). The mean level of IL-1Ra was maximal (26.2 ng/ml) at 5 h and returned to baseline levels between 24 h and 72 h. There were no changes observed in the circulating levels of IL-1 beta in nine out of 11 patients following commencement of surgery. TNF-alpha levels did not increase in any of the patients studied. IL-6 levels increased significantly (P < 0.02) 3 h after commencement of surgery, reaching maximum concentrations at 24 h (range 20-670 pg/ml), with levels falling between 48 h and 72 h. This study demonstrates, in vivo, the independent induction of IL-1Ra without a concomitant increase of IL-1 beta levels after major surgery. It also shows that IL-1Ra is the earliest cytokine produced in response to surgical stress. PMID:8348747

OBJECTIVE Lateral interbody fusion (LIF) with percutaneous screw fixation can treat adult spinal deformity (ASD) in the coronal plane, but sagittal correction is limited. The authors combined LIF with open posterior (OP) surgery using facet osteotomies and a rod-cantilever technique to enhance lumbar lordosis (LL). It is unclear how this hybrid strategy compares to OP surgery alone. The goal of this study was to evaluate the combination of LIF and OP surgery (LIF+OP) for ASD. METHODS All thoracolumbar ASD cases from 2009 to 2014 were reviewed. Patients with < 6 months follow-up, prior fusion, severe sagittal imbalance (sagittal vertical axis > 200 mm or pelvic incidence-LL > 40°), and those undergoing anterior lumbar interbody fusion were excluded. Deformity correction, complications, and outcomes were compared between LIF+OP and OP-only surgery patients. RESULTS LIF+OP (n = 32) and OP-only patients (n = 60) had similar baseline features and posterior fusion levels. On average, 3.8 LIFs were performed. Patients who underwent LIF+OP had less blood loss (1129 vs 1833 ml, p = 0.016) and lower durotomy rates (0% vs 23%, p = 0.002). Patients in the LIF+OP group required less ICU care (0.7 vs 2.8 days, p < 0.001) and inpatient rehabilitation (63% vs 87%, p = 0.015). The incidence of new leg pain, numbness, or weakness was similar between groups (28% vs 22%, p = 0.609). All leg symptoms resolved within 6 months, except in 1 OP-only patient. Follow-up duration was similar (28 vs 25 months, p = 0.462). LIF+OP patients had significantly less pseudarthrosis (6% vs 27%, p = 0.026) and greater improvement in visual analog scale back pain (mean decrease 4.0 vs 1.9, p = 0.046) and Oswestry Disability Index (mean decrease 21 vs 12, p = 0.035) scores. Lumbar coronal correction was greater with LIF+OP surgery (mean [± SD] 22° ± 13° vs 14° ± 13°, p = 0.010). LL restoration was 22° ± 13°, intermediately between OP-only with facet osteotomies (11° ± 7°, p < 0.001) and

Obstructive sleep apnea (OSA) is very frequent and often unrecognized in surgical patients. OSA is associated with perioperative complications. We evaluated the effects of OSA on postoperative complications and hospital outcomes in patients undergoing coronary artery bypass graft (CABG) surgery. Candidates of elective CABG were evaluated by the Berlin questionnaire for OSA. After surgery, patients were assessed for postoperative complications, re-admission to the Intensive Care Unit (ICU), duration of intubation, re-intubation, days spent in the ICU and the hospital. We studied 61 patients who underwent CABG from which 25 (40.9%) patients had OSA. Patients with OSA had higher body mass index (29.5 ± 3.9 vs. 26.0 ± 3.7 kg/m(2), P = 0.003) and higher frequency of hypertension (68.0% vs. 30.5%, P = 0.003), dyslipidemia (36.0% vs. 5.5%, P = 0.004), and pulmonary disease (16.0 vs. 2.7%, P = 0.08). Regarding the surgical outcomes, OSA patients had longer intubation duration (0.75 ± 0.60 vs. 0.41 ± 0.56 days, P = 0.03). Obstructive sleep apnea is frequent, but unrecognized among patients undergoing CABG. In these patients, OSA is associated with prolonged intubation duration. Preventing these problems may be possible by early diagnosis and management of OSA in cardiac surgery patients. Further studies with larger sample of patients and longer follow-ups are required in this regard.

To evaluate the preemptive analgesia effects of both the parecoxib sodium and the pentazocine in patients undergoing nasal endoscopic surgery. In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): group A received parecoxib 40 mg by muscle injection 30 min before the operation; group B received pentazocine 30 mg; group C received an equal volume of saline. The preemptive analgesia effect was evaluated with VAS scores which recorded at different time points. The proportion of participants using rescue analgesia after the operation were recorded as additional measures of preemptive analgesia. Intra-operative as well as the postoperative pain scores were less in the group A and group B than in the control group. Fewer participants required rescue medication after operation with parecoxib as well as pentazocine than placebo. However there were no difference in the preemptive effects between the group A and group B. Administration of both the parecoxib and pentazocine before the nasal endoscopic surgery can provide preemptive analgesia without serious adverse side effects that deserves popularization in the clinic.

Preoperative exposure to clopidogrel and aspirin significantly increases postoperative bleeding in patients undergoing on-pump coronary artery bypass graft surgery. Off-pump coronary bypass grafting has been proposed as an alternative technique to attenuate postoperative bleeding associated with clopidogrel. This study aimed to determine the effects of aspirin and clopidogrel therapy on perioperative blood loss and blood transfusion requirements in off-pump coronary artery bypass grafting. One hundred six patients scheduled for off-pump coronary artery bypass grafting were divided into three groups: aspirin and clopidogrel discontinued more than 6 days before surgery (group 1, n = 35), aspirin and clopidogrel continued until 3 to 5 days before surgery (group 2, n = 51), and both medications continued within 2 days of surgery (group 3, n = 20). Thromboelastographic tracings were analyzed before induction of anesthesia. Routine coagulation profiles were measured before and after surgery. A cell salvage device was used during surgery and salvaged blood was reinfused. Chest tube drainage and blood transfusion requirement were recorded postoperatively. Patient characteristics, operative data, and thromboelastographic tracings were similar among the groups. There were significant decreases in hematocrit level and platelet count and prolongation in prothrombin time postoperatively in all groups without any intergroup differences. The amounts of perioperative blood loss and blood transfusion required were all similar among the groups. Preoperative clopidogrel and aspirin exposure even within 2 days of surgery does not increase perioperative blood loss and blood transfusion requirements in patients undergoing elective off-pump coronary artery bypass grafting.

It is widely believed that the choice between isobaric bupivacaine and hyperbaric bupivacaine formulations alters the block characteristics for the conduct of surgery under spinal anesthesia. The aim of this study was to systematically review the comparative evidence regarding the effectiveness and safety of the 2 formulations when used for spinal anesthesia for adult noncesarean delivery surgery. Key electronic databases were searched for randomized controlled trials, excluding cesarean delivery surgeries under spinal anesthesia, without any language or date restrictions. The primary outcome measure for this review was the failure of spinal anesthesia. Two independent reviewers selected the studies and extracted the data. Results were expressed as relative risk (RR) or mean differences (MDs) with 95% confidence intervals (CIs). Seven hundred fifty-one studies were identified between 1946 and 2016. After screening, there were 16 randomized controlled clinical trials, including 724 participants, that provided data for the meta-analysis. The methodological reporting of most studies was poor, and appropriate judgment of their individual risk of bias elements was not possible. There was no difference between the 2 drugs regarding the need for conversion to general anesthesia (RR, 0.60; 95% CI, 0.08-4.41; P = .62; I = 0%), incidence of hypotension (RR, 1.15; 95% CI, 0.69-1.92; P = .58; I = 0%), nausea/vomiting (RR, 0.29; 95% CI, 0.06-1.32; P = .11; I = 7%), or onset of sensory block (MD = 1.7 minutes; 95% CI, -3.5 to 0.1; P = .07; I = 0%). The onset of motor block (MD = 4.6 minutes; 95% CI, 7.5-1.7; P = .002; I = 78%) was significantly faster with hyperbaric bupivacaine. Conversely, the duration of motor (MD = 45.2 minutes; 95% CI, 66.3-24.2; P < .001; I = 87%) and sensory (MD = 29.4 minutes; 95% CI, 15.5-43.3; P < .001; I = 73%) block was longer with isobaric bupivacaine. Both hyperbaric bupivacaine and isobaric bupivacaine provided effective anesthesia with no

To investigate the frequency, source, and risk factors of intraoperative (IO) surgeon and patient bacterial contamination during clean orthopedic surgeries, and to investigate the relationship between IO contamination and surgical site infection (SSI) in dogs. Prospective clinical study. Client-owned dogs undergoing stifle surgery (n = 100). IO cultures were taken in each case from surgical foot wrap, peri-incisional skin, surgical gloves, and the surgical team's hands. The environment (operating room [OR] lights, computers, scrub sink faucet, anesthesia gurney, and radiology table) was sampled every 5 months. Bacteria were identified and the contamination of each case was categorized. All gloves from the surgical team were collected and tested for perforations using a water infusion test. Cases were followed for at least 8 weeks to determine the presence or absence of SSI. Perioperative variables were evaluated for association with IO contamination and SSI. Bacterial isolates were yielded from 81% of procedures from 1 or more sources; 58% had positive hand cultures, 46% had positive glove cultures, 23% had positive patient skin cultures, and 12% had positive foot wrap cultures. Staphylococcus spp. was the most commonly recovered bacteria. There was no apparent association between IO contamination and SSI. The highest level of environmental contamination was associated with the scrub sink faucet, followed by the radiology table, anesthesia gurney, and OR computers. The IO glove perforation rate was 18%. Clean orthopedic procedures commonly had clinically insignificant bacterial contamination. In our study, bacteria responsible for SSI did not appear to colonize the patient in the OR. © Copyright 2016 by The American College of Veterinary Surgeons.

Although hypothermia and barbiturates improve neurologic outcomes in animal temporary focal ischemia models, the clinical efficacy of these interventions during temporary occlusion of the cerebral vasculature during intracranial aneurysm surgery (temporary clipping) is not established. A post hoc analysis of patients from the Intraoperative Hypothermia for Aneurysm Surgery Trial who underwent temporary clipping was performed. Univariate and multivariate logistic regression methods were used to test for associations between hypothermia, supplemental protective drug, and short- (24-h) and long-term (3-month) neurologic outcomes. An odds ratio more than 1 denotes better outcome. Patients undergoing temporary clipping (n = 441) were assigned to intraoperative hypothermia (33.3 degrees +/- 0.8 degrees C, n = 208) or normothermia (36.7 degrees +/- 0.5 degrees C, n = 233), with 178 patients also receiving supplemental protective drug (thiopental or etomidate) during temporary clipping. Three months after surgery, 278 patients (63%) had good outcome (Glasgow Outcome Score = 1). Neither hypothermia (P = 0.847; odds ratio = 1.043, 95% CI = 0.678-1.606) nor supplemental protective drug (P = 0.835; odds ratio = 1.048, 95% CI = 0.674-1.631) were associated with 3-month Glasgow Outcome Score. The effect of supplemental protective drug did not significantly vary with temperature. The effects of hypothermia and protective drug did not significantly vary with temporary clip duration. Similar findings were made for 24-h neurologic status and 3-month Neuropsychological Composite Score. In the Intraoperative Hypothermia for Aneurysm Surgery Trial, neither systemic hypothermia nor supplemental protective drug affected short- or long-term neurologic outcomes of patients undergoing temporary clipping.

The study included 66 patients undergoing hip replacement surgery. The group consisted of 51 women and 15 men, within the age range of 47-78, the mean age was 64. In 32 (subgroup II) patients the surgery was performed with the use of normovolemic hemodilution, in 34 (subgroup I) the hemodilution procedure was not applied. The enoksaparine as prophylaxis started 12 hours prior to surgery and continued during hospitalisation. The examination of the coagulation system was performed: on the day of the operation in the morning, on the day of the operation in the evening and on the first day after operation. We determined the concentrations of TAT and PAP complexes, prothrombin fragments 1 + 2 (F1 + 2) and d-dimers (DD). 1) during total hip replacement surgery and particularly in the period of the first 12 hours after the procedure marked activation of coagulation and fibrinolysis occurRed; 2) the application of the hemodilution procedure does not influence significantly the degree of coagulation and fibrinolysis disorders in the perioperative period, but could reduced incidence of thromboembolic complications in the postoperative period.

To measure the release of plasma nuclear deoxyribonucleic acid (DNA) and to assess the relationship between nuclear DNA level and acute kidney injury occurrence in patients undergoing cardiac surgery. Cardiovascular anesthesiology and intensive care unit of a large tertiary-care university hospital. Prospective observational study. Fifty adult patients undergoing cardiac surgery. Nuclear DNA concentration was measured in the plasma. The relationship between the level of nuclear DNA and the incidence of acute kidney injury after coronary artery bypass grafting was investigated. Cardiac surgery leads to significant increase in plasma nuclear DNA with peak levels 12 hours after surgery (median [interquartile range] 7.0 [9.6-22.5] µg/mL). No difference was observed between off-pump and on-pump surgical techniques. Nuclear DNA was the only predictor of acute kidney injury between baseline and early postoperative risk factors. The authors found an increase of nuclear DNA in the plasma of patients who had undergone coronary artery bypass grafting, with a peak after 12 hours and an association of nuclear DNA with postoperative acute kidney injury.

Mycotic aneurysms are a serious complication of infective endocarditis with increased risk of intracranial hemorrhage. Patients undergoing open heart surgery for valve repair or replacement are exposed to anticoagulants, increasing the risk of aneurysm bleeding. These patients may require endovascular or surgical aneurysm treatment prior to heart surgery, but data on this approach are scarce. Retrospective review of consecutive patients with infectious endocarditis and mycotic aneurysms treated endovascularly with Trufill n-butyl cyanoacrylate (n-BCA) at the Cleveland Clinic between January 2013 and December 2015. Nine patients underwent endovascular treatment of mycotic aneurysms with n-BCA (mean age of 39 years). On imaging, 4 patients had intracerebral hemorrhage, 2 had multiple embolic infarcts, and the rest had no imaging findings. Twelve mycotic aneurysms were detected (3 patients with 2 aneurysms). Seven aneurysms were in the M4 middle cerebral artery segment, 4 in the posterior cerebral artery distribution, and 1 in the callosomarginal branch. n-BCA was diluted in ethiodized oil (1:1 to 1:2). Embolization was achieved in a single rapid injection with immediate microcatheter removal. Complete aneurysm exclusion was achieved in all cases without complications. All patients underwent open heart surgery and endovascular embolization within a short interval, 2 with both procedures on the same day. There were no new hemorrhages after aneurysm embolization. Endovascular embolization of infectious intracranial aneurysms with liquid embolics can be performed successfully in critically ill patients requiring immediate open heart surgery and anticoagulation. Early embolization prior to and within a short interval from open heart surgery is feasible.

Background and purpose - Detailed information on the symptoms and limitations that patients with meniscal tears experience is lacking. This study was undertaken to map the most prevalent self-reported symptoms and functional limitations among patients undergoing arthroscopic meniscal surgery and investigate which symptoms and limitations had improved most at 1 year after surgery. Patients and methods - Patients aged 18-76 years from the Knee Arthroscopy Cohort Southern Denmark (KACS) undergoing arthroscopic meniscal surgery were included in this analysis of individual subscale items from the Knee Injury and Osteoarthritis Outcome Score and 1 question on knee stability. Severity of each item was scored as none, mild, moderate, severe, or extreme. Improvements were evaluated using Wilcoxon's signed-rank test and effect size (ES). Results - The most common symptoms were knee grinding and clicking, knee pain in general, pain when twisting and bending the knee and climbing stairs (88-98%), while the most common functional limitations were difficulty bending to the floor, squatting, twisting, kneeling, and knee awareness (97-99%). Knee pain in general and knee awareness improved most 1 year after meniscal surgery (ES -0.47 and -0.45; p < 0.001), while knee instability and general knee difficulties improved least (ES 0.10 and -0.08; p < 0.006). Interpretation - Adults undergoing surgery for a meniscal tear commonly report clinical symptoms and functional limitations related to their daily activities. Moderate improvements were observed in some symptoms and functional limitations and small to no improvement in others at 1 year after surgery. These findings can assist the clinical discussion of symptoms, treatments, and patients' expectations.

Numerous studies have demonstrated that bariatric surgery is an effective intervention for morbid obesity, but study samples are characterized by an underrepresentation of young adult patients. The aim of this study was to evaluate weight loss, dietary adherence, and quality of life (QoL) in a multicenter, young adult sample, in the first 6 years after bariatric surgery. Four general hospitals in the Netherlands. A total of 184 young adult patients who underwent bariatric surgery between 6 and 74 months previously at the age of 18 to 24 years were included, interviewed by phone, and sent questionnaires assessing postoperative weight, QoL, and lifestyle behaviors including dietary adherence. Complete data were available for those 96 patients who returned the questionnaires. Mean percent weight loss was 30.2 (SD 10.7) for laparoscopic sleeve gastrectomy and 35.6 (SD 6.9) for laparoscopic Roux-en-Y gastric bypass. Adherence to postoperative dietary recommendations declined over the years (r = -.25, P = .02) and explained 8.3% of the variance in weight loss (r = .29, P = .005). QoL scores lagged behind national norms for young adults and were largely unrelated to weight loss. A quarter of patients (25%) turned out to be not in education, employment, or training and 38% had used mental healthcare services since surgery, which occurred independent of weight loss and concurred with poorer QoL. Young adult patients achieve weight loss comparable to adult patients after bariatric surgery. However, postoperative adherence to behavioral recommendations and psychosocial functioning clearly demonstrate room for improvement and require adjunctive interventions.

The long-term use of milrinone is associated with increased mortality in chronic heart failure. A recent meta-analysis suggested that it might increase mortality in patients undergoing cardiac surgery. The authors conducted an updated meta-analysis of randomized trials in patients undergoing cardiac surgery to determine if milrinone impacted survival. A meta-analysis. Hospitals. One thousand thirty-seven patients from 20 randomized trials. None. Biomed, Central, PubMed, EMBASE, the Cochrane central register of clinical trials, and conference proceedings were searched for randomized trials that compared milrinone versus placebo or any other control in adult and pediatric patients undergoing cardiac surgery. Authors of trials that did not include mortality data were contacted. Only trials for which mortality data were available were included. Overall analysis showed no difference in mortality between patients receiving milrinone versus control (12/554 [2.2%] in the milrinone group v 10/483 [2.1%] in the control arm; relative risk [RR] = 1.15; 95% confidence interval [CI], 0.55-2.43; p = 0.7) or in analysis restricted to adults (11/364 [3%] in the milrinone group v 9/371 [2.4%] in the control arm; RR = 1.17; 95% CI, 0.54-2.53; p = 0.7). Sensitivity analyses in trials with a low risk of bias showed a trend toward an increase in mortality with milrinone (8/153 [5.2%] in the milrinone arm v 2/152 [1.3%] in the control arm; RR = 2.71; 95% CI, 0.82-9; p for effect = 0.10). Despite theoretic concerns for increased mortality with intravenous milrinone in patients undergoing cardiac surgery, the authors were unable to confirm an adverse effect on survival. However, sensitivity analysis of high-quality trials showed a trend toward increased mortality with milrinone. Copyright © 2013 Elsevier Inc. All rights reserved.

OBJECTIVE Recommendations for the surgical treatment of isolated lumbar spinal stenosis (LSS) (i.e., in the absence of concomitant scoliosis or spondylolisthesis) are unclear. The aims of this study were to investigate trends in the surgical treatment of isolated LSS in US adults and determine implications for outcomes. METHODS The authors analyzed inpatient and outpatient claims from the Truven Health Analytics MarketScan Commercial Claims and Encounters Database for 20,279 patients aged 40-64 years who underwent surgery for LSS between 2010 and 2014. Only patients with continuous 12-month insurance coverage after surgery were included. The rates of decompression with arthrodesis versus decompression only and of simple (1- or 2-level, single-approach) versus complex (> 2-level or combined-approach) arthrodesis were analyzed by year and geographic region. These trends were further analyzed with respect to complications, length of hospital stay, payments made to the hospital, and patient discharge status. Statistical significance was set at p < 0.05. RESULTS The proportion of patients who underwent decompression with arthrodesis compared with decompression only increased significantly and linearly from 2010 to 2014 (OR 1.08; 95% CI 1.06-1.10). Arthrodesis was more likely to be complex rather than simple with each subsequent year (OR 1.4; 95% CI 1.33-1.49). This trend was accompanied by an increased likelihood of postoperative complications (OR 1.11; 95% CI 1.02-1.21), higher costs (payments increased by a mean of US$1633 per year; 95% CI 1327-1939), and greater likelihood of being discharged to a skilled nursing facility as opposed to home (OR 1.11; 95% CI 1.03-1.20). The South and Midwest regions of the US had the highest proportions of patients undergoing arthrodesis (48% and 42%, respectively). The mean length of hospital stay did not change significantly (p = 0.324). CONCLUSIONS From 2010 to 2014, the proportion of adults undergoing decompression with

The fourth-generation FloTrac/Vigileo™ improved its algorithm to follow changes in systemic vascular resistance index (SVRI). This revision may improve the accuracy and trending ability of CI even in patients who undergo abdominal aortic aneurysm (AAA) surgery which cause drastic change of SVRI by aortic clamping. The purpose of this study is to elucidate the accuracy and trending ability of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery by comparing the FloTrac/Vigileo™-derived CI (CI FT ) with that measured by three-dimensional echocardiography (CI 3D ). Twenty-six patients undergoing elective AAA surgery were included in this study. CI FT and CI3 D were determined simultaneously in eight points including before and after aortic clamp. We used CI 3D as the reference method. In the Bland-Altman analysis, CI FT had a wide limit of agreement with CI 3D showing a percentage error of 46.7%. Subgroup analysis showed that the percentage error between CO 3D and CO FT was 56.3% in patients with cardiac index < 2.5 L/min/m 2 and 28.4% in patients with cardiac index ≥ 2.5 L/min/m 2 . SVRI was significantly higher in patients with cardiac index < 2.5 L/min/m 2 (1703 ± 330 vs. 2757 ± 798; p < 0.001). The tracking ability of fourth generation of FloTrac/Vigileo™ after aortic clamp was not clinically acceptable (26.9%). The degree of accuracy of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery was not acceptable. The tracking ability of the fourth-generation FloTrac/Vigileo™ after aortic clamp was below the acceptable limit.

Factors contributing to postoperative complications include blood loss and a heightened inflammatory response. The objective of this study was to test the hypothesis that aprotinin would decrease perioperative blood product use, reduce biomarkers of inflammation, and result in improved clinical outcome parameters in neonates undergoing cardiac operations. This was a secondary retrospective analysis of a clinical trial whereby neonates undergoing cardiac surgery received either aprotinin (n = 34; before May 2008) or tranexamic acid (n = 42; after May 2008). Perioperative blood product use, clinical course, and measurements of cytokines were compared. Use of perioperative red blood cells, cryoprecipitate, and platelets was reduced in neonates receiving aprotinin compared with tranexamic acid (P < .05). Recombinant activated factor VII use (2/34 [6%] vs 18/42 [43%]; P < .001), delayed sternal closure (12/34 [35%] vs 26/42 [62%]; P = .02), and inotropic requirements at 24 and 36 hours (P < .05) were also reduced in the aprotinin group. Median duration of mechanical ventilation was reduced compared with tranexamic acid: 2.9 days (interquartile range: 1.7-5.1 days) versus 4.2 days (2.9-5.2 days), P = .04. Production of tumor necrosis factor and interleukin-2 activation were attenuated in the aprotinin group at 24 hours postoperatively. No differential effects on renal function were seen between agents. Aprotinin, compared with tranexamic acid, was associated with reduced perioperative blood product use, improved early indices of postoperative recovery, and attenuated indices of cytokine activation, without early adverse effects. These findings suggest that aprotinin may have unique effects in the context of neonatal cardiac surgery and challenge contentions that antifibrinolytics are equivalent with respect to early postoperative outcomes.

Sarcopenia, severe skeletal muscle loss, has been identified as a prognostic factor in various malignancies. This study aims to investigate whether sarcopenia is associated with overall survival (OS) and surgical complications in patients with advanced ovarian cancer undergoing primary debulking surgery (PDS). Ovarian cancer patients (n = 216) treated with PDS were enrolled retrospectively. Total skeletal muscle surface area was measured on axial computed tomography at the level of the third lumbar vertebra. Optimum stratification was used to find the optimal skeletal muscle index cut-off to define sarcopenia (≤38.73 cm 2 /m 2 ). Cox-regression and Kaplan-Meier analysis were used to analyse the relationship between sarcopenia and OS. The effect of sarcopenia on the development of major surgical complications was studied with logistic regression. Kaplan-Meier analysis showed a significant survival disadvantage for patients with sarcopenia compared to patients without sarcopenia (p = 0.010). Sarcopenia univariably predicted OS (HR 1.536 (95% CI 1.105-2.134), p = 0.011) but was not significant in multivariable Cox-regression analysis (HR 1.362 (95% CI 0.968-1.916), p = 0.076). Significant predictors for OS in multivariable Cox-regression analysis were complete PDS, treatment in a specialised centre and the development of major complications. Sarcopenia was not predictive of major complications. Sarcopenia was not predictive of OS or major complications in ovarian cancer patients undergoing primary debulking surgery. However a strong trend towards a survival disadvantage for patients with sarcopenia was seen. Future prospective studies should focus on interventions to prevent or reverse sarcopenia and possibly increase ovarian cancer survival. Complete cytoreduction remains the strongest predictor of ovarian cancer survival.

To investigate the correlation and accuracy of transcutaneous carbon dioxide partial pressure (PTCCO2) with regard to arterial carbon dioxide partial pressure (PaCO2) in severe obese patients undergoing laparoscopic bariatric surgery. Twenty-one patients with BMI>35 kg/m2 were enrolled in our study. Their PaCO2, end-tidal carbon dioxide partial pressure (PetCO2), as well as PTCCO2 values were measured at before pneumoperitoneum and 30 min, 60 min, 120 min after pneumoperitoneum respectively. Then the differences between each pair of values (PetCO2–PaCO2) and. (PTCCO2–PaCO2) were calculated. Bland–Altman method, correlation and regression analysis, as well as exact probability method and two way contingency table were employed for the data analysis. 21 adults (aged 19–54 yr, mean 29, SD 9 yr; weight 86–160 kg, mean119.3, SD 22.1 kg; BMI 35.3–51.1 kg/m2, mean 42.1,SD 5.4 kg/m2) were finally included in this study. One patient was eliminated due to the use of vaso-excitor material phenylephrine during anesthesia induction. Eighty-four sample sets were obtained. The average PaCO2–PTCCO2 difference was 0.9±1.3 mmHg (mean±SD). And the average PaCO2–PetCO2 difference was 10.3±2.3 mmHg (mean±SD). The linear regression equation of PaCO2–PetCO2 is PetCO2 = 11.58+0.57×PaCO2 (r2 = 0.64, P<0.01), whereas the one of PaCO2–PTCCO2 is PTCCO2 = 0.60+0.97×PaCO2 (r2 = 0.89). The LOA (limits of agreement) of 95% average PaCO2–PetCO2 difference is 10.3±4.6 mmHg (mean±1.96 SD), while the LOA of 95% average PaCO2–PTCCO2 difference is 0.9±2.6 mmHg (mean±1.96 SD). In conclusion, transcutaneous carbon dioxide monitoring provides a better estimate of PaCO2 than PetCO2 in severe obese patients undergoing laparoscopic bariatric surgery. PMID:24699267

Direct medical and non-medical costs incurred by those undergoing subsidised cataract surgery at Gusau eye clinic, Zamfara state, were recently determined. The aim of this study was to assess the willingness to pay for cataract surgery among adults with severe visual impairment or blindness from cataract in rural Zamfara and to compare this to actual costs. In three rural villages served by Gusau eye clinic, key informants helped identify 80 adults with bilateral severe visual impairment or blindness (<6/60), with cataract being the cause in at least one eye. The median amount participants were willing to pay for cataract surgery was determined. The proportion willing to pay actual costs of the (i) subsidised surgical fee (US$18.5), (ii) average non-medical expenses (US$25.2), and (iii) average total expenses (US$51.2) at Gusau eye clinic were calculated. Where participants would seek funds for surgery was determined. Among 80 participants (38% women), most (n = 73, 91%) were willing to pay something, ranging from surgery among adults with operable cataract in rural Zamfara state is far lower than current costs of undergoing surgery. People who were widowed-most of whom were women-were willing to pay least. Further financial support is required for cataract surgery to be universally accessible.

In contrast to the results of previous studies, recent randomized controlled trials (RCTs) failed to show a benefit of prophylactic aortic counterpulsation in high-risk patients undergoing cardiac surgery. The present analysis aims to redefine the effects of this treatment modality in the light of this new evidence. MEDLINE, EMBASE, CENTRAL/CCTR, Google Scholar and reference lists of relevant articles were searched for full-text articles of RCTs in English or German. Assessments for eligibility, relevance, study validity and data extraction were performed by two reviewers independently using prespecified criteria. The primary outcome was hospital mortality. A total of nine eligible RCTs with 1171 patients were identified: 577 patients were treated preoperatively with intra-aortic balloon pump (IABP) and 594 patients served as controls. The pooled odds ratio (OR) for hospital mortality (22 hospital deaths in the intervention arm, 54 in the control group) was 0.381 (95% CI 0.230-0.629; P < 0.001). The pooled analyses of five RCTs including only patients undergoing isolated on-pump coronary artery bypass grafting (n[IABP] = 348, n[control] = 347) also showed a statistically significant improvement in mortality for preoperative IABP implantation (fixed-effects model: OR 0.267, 95% CI 0.129-0.552, P < 0.001). The pooled OR for hospital mortality from two randomized off-pump trials was 0.556 (fixed-effects model, 95% CI 0.207-1.493, P = 0.226). Preoperative aortic counterpulsation was associated with a significant reduction in low cardiac output syndrome (LCOS) in the total population (fixed-effects model: OR 0.330, 95% CI 0.214-0.508, P < 0.001) as well as in the subgroup of CAGB patients (fixed-effects model: OR 0.113, 95% CI 0.056-0.226, P < 0.001), whereas there was no benefit in the off-pump population (fixed-effects model: OR 0.555, 95% CI 0.209-1.474, P = 0.238). Preoperative IABP implantation was associated with a reduction of intensive care unit (ICU) stay in

To investigate the effects of parecoxib sodium preemptive analgesia on perioperative cytokine responses and stress responses and postoperative analgesia in patients undergoing ophthalmology surgery. One hundred ASAI-II patients undergoing ophthalmology surgery were randomly divided into 2 groups of fifty: the parecoxib group received parecoxib 40 mg by muscle injection, the control group received an equal volume of 0.9% normal saline two ml. Venous blood samples were obtained at 10 minutes before parecoxib or 0.9% normal saline was injected (T1), 30 minutes (T2) and 60 minutes (T3) after surgery was initiated, the moment when surgery was finished (T4), 6 hours (T5), 12 hours (T6) and 24 hours (T7) after surgery was finished for determination of the plasma levels of IL-6, IL-8, IL-1RA, TNF and IL-1β. At the same time, the plasma levels of epinephrine, norepinephrine, cortisol and adrenocorticotropic hormone at T1-T6 were measured. VAS scores with patients were recorded at 1, 2, 6, 12, 24 h after surgery. The change of the plasma levels of IL-6, IL-8, IL-1RA, TNF, IL-1β in the two groups:in the parecoxib group the plasma levels of TNF and IL-1β did not decreased significantly as compared with the control group (P > 0.05). The plasma levels of IL-6, IL-8 at T4-T6 decreased significantly as compared with the control group (P < 0.01). The plasma levels of IL-1RA at T3-T6 decreased significantly as compared with the control group (P < 0.01). The change of the plasma levels of epinephrine, norepinephrine, cortisol and adrenocorticotropic hormone in the two groups:in the parecoxib group the plasma levels of epinephrine, norepinephrine at T2, T3 decreased significantly as compared with the control group (P < 0.01). In the parecoxib group the plasma levels of cortisol at T2-T4 decreased significantly as compared with the control group (P < 0.01). In the parecoxib group the plasma levels of adrenocorticotropic hormone at T2-T5 decreased significantly as compared with the

Although it has been widely demonstrated that administration of Daikenchuto (DKT), a traditional Japanese herbal medicine, improves gastrointestinal (GI) motility in patients undergoing abdominal surgery, few studies have investigated the efficacy of perioperative DKT administration for relief of postoperative ileus (PI) in patients undergoing surgery for GI cancer. Therefore, the aim of this study was to investigate whether perioperative administration of DKT relieves PI in patients with GI cancer. We performed a comprehensive electronic search of the literature (Cochrane Library, PubMed, the Web of Science and ICHUSHI) up to December 2016 to identify studies that had shown the efficacy of perioperative DKT administration for relief of PI in patients with GI cancer. To integrate the individual effect of DKT, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I 2 statistics. Seven studies involving a total of 1,134 patients who had undergone GI cancer surgery were included in this meta-analysis. Among 588 patients who received DKT perioperatively, 67 (11.4%) had PI, whereas among 546 patients who did not receive DKT perioperatively, 87 (15.9%) had PI. Perioperative administration of DKT significantly reduced the occurrence of PI (RR=0.58, 95% CI=0.35-0.97, p=0.04, I 2 =48%) in comparison to patients who did not receive DKT or received placebo. The result of this meta-analysis suggests that perioperative administration of DKT relieves PI in patients undergoing surgery for GI cancer.

To evaluate the changes of perioperative plasma concentrations of Aβ 1-40 and S-100β to determine the relationship with postoperative cognitive dysfunction in elderly patients undergoing oral and maxillofacial cancer surgeries. One hundred and fifteen patients aged at least 60 years undergoing oral and maxillofacial tumor resection were investigated between May 2014 to December 2014.Neuropsychological tests for detecting postoperative cognitive dysfunction(POCD) were performed one day before surgery and 7 days postoperatively. According to the results of neuropsychological tests on day 7, patients were divided into POCD group and non-POCD group.Plasma values of Aβ 1-40 and S-100β were determined with enzyme linked immunosorbent assay (ELISA) before anesthesia induction, 24 h and 7 days after surgery. The data were analyzed using SPSS 19.0 software package. According to the definition, POCD was present in 37 of 115 (32.3%) patients 1 week after surgery. Compared with pre-anesthesia, S-100β levels in POCD group were significantly increased (P<0.05); the level of Aβ 1-40 was significantly higher 24 h after surgery (P<0.05). Compared with non-POCD group, S-100β levels were significantly increased 24 h postoperatively (P<0.05); Aβ1-40 levels were significantly higher 24 h and 7 days postoperatively (P<0.05). POCD was present in 32.2% of patients on day 7 after oral and maxillofacial surgeries with general anesthesia. The increasing levels of Aβ 1-40 , S-100β may be associated with the occurence of POCD. Patients with long-lasting operation and high concentrations of Aβ 1-40 and S-100β after surgeries were at a higher risk of POCD. The clinical values of Aβ 1-40 and S-100 as predictive measurements of POCD after oral and maxillofacial cancer surgery appear to be reasonable.

Owing to advances in cardiovascular surgery, patients with cardiovascular disease require improvement of health-related quality of life (QOL) than before. We measured the QOL of patients undergoing cardiovascular surgery using the eight-item Short Form (SF-8) and assessed its usefulness. This was a prospective repeated-measures observational study. The SF-8 questionnaire was completed through interviews with 117 consecutive adult patients undergoing cardiovascular surgery at a single center (Nagara Medical Center, Japan) from April 2006 to March 2008. The SF-8 was evaluated before surgery and at 7 days, 1 month, and 6 months after surgery. The physical and mental scores over time were assessed. Regarding physical status, compared with the normal population, the patients' scores were worse preoperatively and had deteriorated 7 days postoperatively; they gradually got closer to preoperative status a month after the procedure. At 6 months after surgery, all physical scores were higher than before surgery. The mental scores, including a mental component summary score, were inferior to those of the normal population until 1 month postoperatively, and they reached those of the normal population at 6 months. The SF-8 changed with the postoperative time course. It was a useful tool for analyzing the physical and mental QOL of patients who underwent cardiovascular surgery.

We investigated the effects of the beach-chair position and induced hypotension on regional cerebral oxygen saturation (rSO(2)) in patients undergoing arthroscopic shoulder surgery by using near-infrared spectroscopy. Twenty-eight patients scheduled for arthroscopic shoulder surgery were enrolled prospectively. After induction of anesthesia, mechanical ventilation was controlled to maintain Paco(2) at 35 to 40 mm Hg. Anesthesia was maintained with sevoflurane and remifentanil. After radial artery cannulation, mean arterial pressure (MAP) was measured at the external auditory meatus level and maintained between 60 and 65 mm Hg. The rSO(2) was measured by use of near-infrared spectroscopy. MAP and rSO(2) were recorded at the following times: before induction (T(0)), immediately after induction (T(1) [baseline]), after beach-chair position (T(2)), immediately after induced hypotension (T(3)), 1 hour after induced hypotension (T(4)), and after supine position at the end of surgery (T(5)). Cerebral desaturation was defined as a reduction in rSO(2) to less than 80% of baseline value for 15 seconds or greater. A total of 27 patients were evaluated until the end of this study. The MAP at T(2) was significantly lower than that at T(1). The MAP values at T(3) and T(4) were significantly lower than those at T(1) and T(2). The rSO(2) at T(2) was significantly lower than that at T(1). Unlike the pattern of change in the MAP, there was no additional decrease in rSO(2) at T(3) and T(4). There were 2 patients who had an episode of cerebral desaturation. The beach-chair position combined with induced hypotension significantly decreases rSO(2) in patients undergoing shoulder arthroscopic surgery under general anesthesia.

To assess the outcome of patients treated conservatively vs surgically during their first admission for sigmoid volvulus. We conducted a retrospective study of 61 patients admitted to Aarhus University Hospital in Denmark between 1996 and 2011 for their first incidence of sigmoid volvulus. The condition was diagnosed by radiography, sigmoidoscopy or surgery. Patients treated with surgery underwent either a sigmoid resection or a percutaneous endoscopic colostomy (PEC). Conservatively treated patients were managed without surgery. Data was recorded into a Microsoft Access database and calculations were performed with Microsoft Excel. Kaplan-Meier plotting and Mantel-Cox (log-rank) testing were performed using GraphPad Prism software. Mortality was defined as death within 30 d after intervention or surgery. Among the total 61 patients, 4 underwent emergency surgery, 55 underwent endoscopy, 1 experienced resolution of the volvulus after contrast enema, and 1 died without treatment because of large bowel perforation. Following emergency treatment, 28 patients underwent sigmoid resection (semi-elective n = 18; elective n = 10). Two patients who were unfit for surgery underwent PEC and both died, 1 after 36 d and the other after 9 mo, respectively. The remaining 26 patients were managed conservatively without sigmoid resection. Patients treated conservatively on their first admission had a poorer survival rate than patients treated surgically on their first admission (95%CI: 3.67-14.37, P = 0.036). Sixty-three percent of the 26 conservatively treated patients had not experienced a recurrence 3 mo after treatment, but that number dropped to 24% 2 years after treatment. Eight of the 14 patients with recurrence after conservative treatment had surgery with no 30-d mortality. Surgically-treated sigmoid volvulus patients had a higher long-term survival rate than conservatively managed patients, indicating a benefit of surgical resection or PEC insertion if feasible.

Background Antibiotics play an important role in the treatment of many surgical diseases that affect older adults, and the potential for inappropriate use of these drugs is high. Our objective was to describe antibiotic use among older adults admitted to an acute care surgery service at a tertiary care teaching hospital. Methods Detailed data regarding diagnosis, comorbidities, surgery and antibiotic use were retrospectively collected for patients 70 years and older admitted to an acute care surgery service. We evaluated antibiotic use (perioperative prophylaxis and treatment) for appropriateness based on published guidelines. Results During the study period 453 patients were admitted to the acute care surgery service, and 229 underwent surgery. The most common diagnoses were small bowel obstruction (27.2%) and acute cholecystitis (11.0%). In total 251 nonelective abdominal operations were performed, and perioperative antibiotic prophylaxis was appropriate in 49.5% of cases. The most common prophylaxis errors were incorrect timing (15.5%) and incorrect dose (12.4%). Overall 206 patients received treatment with antibiotics for their underlying disease process, and 44.2% received appropriate first-line drug therapy. The most common therapeutic errors were administration of second- or third-line antibiotics without indication (37.9%) and use of antibiotics when not indicated (12.1%). There was considerable variation in the duration of treatment for patients with the same diagnoses. Conclusion Inappropriate antibiotic use was common among older patients admitted to an acute care surgery service. Quality improvement initiatives are needed to ensure patients receive optimal care in this complex hospital environment. PMID:28930045

Perioperative hypothermia has been reported to increase the occurrence of cardiovascular complications. By increasing the activity of sympathetic nervous system, perioperative hypothermia also has the potential to increase cardiac injury and dysfunction associated with subarachnoid hemorrhage. The Intraoperative Hypothermia for Aneurysm Surgery Trial randomized patients undergoing cerebral aneurysm surgery to intraoperative hypothermia (n = 499, 33.3 degrees +/- 0.8 degrees C) or normothermia (n = 501, 36.7 degrees +/- 0.5 degrees C). Cardiovascular events (hypotension, arrhythmias, vasopressor use, myocardial infarction, and others) were prospectively followed until 3-month follow-up and were compared in hypothermic and normothermic patients. A subset of 62 patients (hypothermia, n = 33; normothermia, n = 29) also had preoperative and postoperative (within 24 h) measurement of cardiac troponin-I and echocardiography to explore the association between perioperative hypothermia and subarachnoid hemorrhage-associated myocardial injury and left ventricular function. There was no difference between hypothermic and normothermic patients in the occurrence of any single cardiovascular event or in composite cardiovascular events. There was no difference in mortality (6%) between groups, and there was only a single primary cardiovascular death (normothermia). There was no difference between hypothermic and normothermic patients in postoperative versus preoperative left ventricular regional wall motion or ejection fraction. Compared with preoperative values, hypothermic patients had no postoperative increase in cardiac troponin-I (median change 0.00 microg/l), whereas normothermic patients had a small postoperative increase (median change + 0.01 microg/l, P = 0.038). In patients undergoing cerebral aneurysm surgery, perioperative hypothermia was not associated with an increased occurrence of cardiovascular events.

Health locus of control in patients undergoing coronary artery surgery - changes and associated outcomes: a seven-year cohort study.

PubMed

Rideout, Andrew; Tolmie, Elizabeth; Lindsay, Grace

Health locus of control is a measure of an individual's beliefs in factors that are thought to determine health experiences. Scores are generated and form a graduated linear scale from external to internal control, with respect to their views on health causality. Health locus of control has been considered to be a relatively stable entity. However, it is not clear if this status changes in the advent of serious health challenges, such as coronary artery bypass graft surgery. The aim of this study is to explore the variability of health locus of control and its association with postoperative health in this context. In a longitudinal cohort study of patients undergoing coronary artery bypass graft surgery, a purposive sample ( n=215) were recruited from the waiting list and followed up postoperatively, at approximately one year and seven years later. Patients undergoing coronary artery bypass graft surgery demonstrated marked fluctuations in health locus of control in their peri-operative and rehabilitative phases. Mean health locus of control became more external (often associated with poorer outcomes) peri-operatively, and more internal (generally associated with better health outcomes) in the rehabilitative period. Health locus of control scores were shown to be changeable during a major health care intervention, with possible consequences for patient outcomes and care needs. The significant health belief upheaval demonstrated in this cohort should be considered in assessing patients preoperatively, and managed as part of the patients' clinical journey by both acute and rehabilitation staff. It is likely to have particular importance in individualised assessment and management of future prevention advice for patients.

In children undergoing congenital heart surgery, plasma brain natriuretic peptide levels may have a role in development of low cardiac output syndrome that is defined as a combination of clinical findings and interventions to augment cardiac output in children with pulmonary hypertension. In a prospective observational study, fifty-one children undergoing congenital heart surgery with preoperative echocardiographic study showing pulmonary hypertension were enrolled. The plasma brain natriuretic peptide levels were collected before operation, 12, 24 and 48h after operation. The patients enrolled into the study were divided into two groups depending on: (1) Development of LCOS which is defined as a combination of clinical findings or interventions to augment cardiac output postoperatively; (2) Determination of preoperative brain natriuretic peptide cut-off value by receiver operating curve analysis for low cardiac output syndrome. The secondary end points were: (1) duration of mechanical ventilation ≥72h, (2) intensive care unit stay >7days, and (3) mortality. The differences in preoperative and postoperative brain natriuretic peptide levels of patients with or without low cardiac output syndrome (n=35, n=16, respectively) showed significant differences in repeated measurement time points (p=0.0001). The preoperative brain natriuretic peptide cut-off value of 125.5pgmL-1 was found to have the highest sensitivity of 88.9% and specificity of 96.9% in predicting low cardiac output syndrome in patients with pulmonary hypertension. A good correlation was found between preoperative plasma brain natriuretic peptide level and duration of mechanical ventilation (r=0.67, p=0.0001). In patients with pulmonary hypertension undergoing congenital heart surgery, 91% of patients with preoperative plasma brain natriuretic peptide levels above 125.5pgmL-1 are at risk of developing low cardiac output syndrome which is an important postoperative outcome.

To study the association between ketorolac use and postoperative complications. Nonsteroidal anti-inflammatory drugs may impair wound healing and increase the risk of anastomotic leak in colon surgery. Studies to date have been limited by sample size, inability to identify confounding, and a focus limited to colon surgery. Ketorolac use, reinterventions, emergency department (ED) visits, and readmissions in adults (≥ 18 years) undergoing gastrointestinal (GI) operations was assessed in a nationwide cohort using the MarketScan Database (2008-2012). Among 398,752 patients (median age 52, 45% male), 55% underwent colorectal surgery, whereas 45% had noncolorectal GI surgery. Five percent of patients received ketorolac. Adjusting for demographic characteristics, comorbidities, surgery type/indication, and preoperative medications, patients receiving ketorolac had higher odds of reintervention (odds ratio [OR] 1.20, 95% confidence interval [CI] 1.08-1.32), ED visit (OR 1.44, 95% CI 1.37-1.51), and readmission within 30 days (OR 1.11, 95% CI 1.05-1.18) compared to those who did not receive ketorolac. Ketorolac use was associated with readmissions related to anastomotic complications (OR 1.20, 95% CI 1.06-1.36). Evaluating only admissions with ≤ 3 days duration to exclude cases where ketorolac might have been used for complication-related pain relief, the odds of complications associated with ketorolac were even greater. Use of intravenous ketorolac was associated with greater odds of reintervention, ED visit, and readmission in both colorectal and noncolorectal GI surgery. Given this confirmatory evaluation of other reports of a negative association and the large size of this cohort, clinicians should exercise caution when using ketorolac in patients undergoing GI surgery.

To integrate literature data on the predictors of excessive bleeding after cardiac surgery in adults. Perioperative nursing care requires awareness of the risk factors for excessive bleeding after cardiac surgery to assure vigilance prioritising and early correction of those that are modifiable. Integrative literature review. Articles were searched in seven databases. Seventeen studies investigating predictive factors for excessive bleeding after open-heart surgery from 2004-2014 were included. Predictors of excessive bleeding after cardiac surgery were: Patient-related: male gender, higher preoperative haemoglobin levels, lower body mass index, diabetes mellitus, impaired left ventricular function, lower amount of prebypass thrombin generation, lower preoperative platelet counts, decreased preoperative platelet aggregation, preoperative platelet inhibition level >20%, preoperative thrombocytopenia and lower preoperative fibrinogen concentration. Procedure-related: the operating surgeon, coronary artery bypass surgery with three or more bypasses, use of the internal mammary artery, duration of surgery, increased cross-clamp time, increased cardiopulmonary bypass time, lower intraoperative core body temperature and bypass-induced haemostatic disorders. Postoperative: fibrinogen levels and metabolic acidosis. Patient-related, procedure-related and postoperative predictors of excessive bleeding after cardiac surgery were identified. The predictors summarised in this review can be used for risk stratification of excessive bleeding after cardiac surgery. Assessment, documentation and case reporting can be guided by awareness of these factors, so that postoperative vigilance can be prioritised. Timely identification and correction of the modifiable factors can be facilitated. © 2015 John Wiley & Sons Ltd.

To investigate the incidence and predictive factors of 30-day surgery-related morbidity and occult precancerous and cancerous conditions for women undergoing risk-reducing surgery. A prospective study (Canadian Task Force classification II-1). A gynecologic oncology referral center. Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). Minimally invasive risk-reduction surgery. Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery. Copyright © 2017 AAGL. Published by Elsevier Inc.

Total knee and total hip arthoplasty (THA) are 2 of the most common surgical procedures performed in the United States and represent the greatest single Medicare procedural expenditure. This study was designed to evaluate the economic impact of implementing a multimodal analgesic regimen (Total Joint Regional Anesthesia [TJRA] Clinical Pathway) on the estimated direct medical costs of patients undergoing lower extremity joint replacement surgery. An economic cost comparison was performed on Mayo Clinic patients (n = 100) undergoing traditional total knee or total hip arthroplasty using the TJRA Clinical Pathway. Study patients were matched 1:1 with historical controls undergoing similar procedures using traditional anesthetic (non-TJRA) techniques. Matching criteria included age, sex, surgeon, type of procedure, and American Society of Anesthesiologists (ASA) physical status (PS) classification. Hospital-based direct costs were collected for each patient and analyzed in standardized inflation-adjusted constant dollars using cost-to-charge ratios, wage indexes, and physician services valued using Medicare reimbursement rates. The estimated mean direct hospital costs were compared between groups, and a subgroup analysis was performed based on ASA PS classification. The estimated mean direct hospital costs were significantly reduced among TJRA patients when compared with controls (cost difference, 1999 dollars; 95% confidence interval, 584-3231 dollars; P = 0.0004). A significant reduction in hospital-based (Medicare Part A) costs accounted for the majority of the total cost savings. Use of a comprehensive, multimodal analgesic regimen (TJRA Clinical Pathway) in patients undergoing lower extremity joint replacement surgery provides a significant reduction in the estimated total direct medical costs. The reduction in mean cost is primarily associated with lower hospital-based (Medicare Part A) costs, with the greatest overall cost difference appearing among patients

We aim to identify preoperative factors at diagnosis which could predict whether women undergoing wide local excision (WLE) would require further operations. 1593 screen-detected invasive and non-invasive breast cancers were reviewed. Age, presence of ductal carcinoma in situ (DCIS), invasive cancer size on mammography, mammographic sign, tumour type, grade and confidence of the radiologist in malignancy were compared. 83%(1315/1593) of women had a WLE. Of these, 70%(919/1315) had a single operation, and 30%(396/1315) multiple operations. These included repeat WLE to clear margins (60%(238/396)), mastectomy (34%(133/396)) and axillary dissection (6%(25/396)). The presence of mammographic microcalcification, lobular carcinoma and grade 2 malignancy on core biopsy were independent risk factors for multiple operations on multivariate analysis. Women with mammographic DCIS >30 mm were 3.4 times more likely to undergo repeat surgery than those with smaller foci. The multidisciplinary team should pay particular attention to these factors when planning surgery. Copyright © 2012 Elsevier Ltd. All rights reserved.

Objective. Our present study tested whether flurbiprofen axetil could reduce perioperative sufentanil consumption and provide postoperative analgesia with decrease in emergency agitation and systemic proinflammatory cytokines release. Methods. Ninety patients undergoing tangential excision surgery were randomly assigned to three groups: (1) preoperative dose of 100 mg flurbiprofen axetil and a postoperative dose of 2 μg/kg sufentanil and 10 mL placebo by patient-controlled analgesia (PCA) pump, (2) preoperative dose of 100 mg flurbiprofen axetil and a postoperative dose of 2 μg/kg sufentanil and 100 mg flurbiprofen axetil by PCA pump, and (3) 10 mL placebo and a postoperative dose of 2 μg/kg sufentanil and 10 mL placebo by PCA pump. Results. Preoperative administration of flurbiprofen axetil decreased postoperative tramadol consumption and the visual analog scale at 4, 6, 12, and 24 h after surgery, which were further decreased by postoperative administration of flurbiprofen axetil. Furthermore, flurbiprofen axetil attenuated emergency agitation score and Ramsay score at 0, 5, and 10 min after extubation and reduced the TNF-α and interleukin- (IL-) 6 levels at 24 and 48 h after the operation. Conclusion. Flurbiprofen axetil enhances analgesic effects of sufentanil and attenuates emergence agitation and systemic proinflammation in patients undergoing tangential excision surgery.

Fluid strategies may impact on patient outcomes in major elective surgery. We aimed to study the effectiveness and cost-effectiveness of pre-operative fluid loading in high-risk surgical patients undergoing major elective surgery. This was a pragmatic, non-blinded, multi-centre, randomised, controlled trial. We sought to recruit 128 consecutive high-risk surgical patients undergoing major abdominal surgery. The patients underwent pre-operative fluid loading with 25 ml/kg of Ringer's solution in the six hours before surgery. The control group had no pre-operative fluid loading. The primary outcome was the number of hospital days after surgery with cost-effectiveness as a secondary outcome. A total of 111 patients were recruited within the study time frame in agreement with the funder. The median pre-operative fluid loading volume was 1,875 ml (IQR 1,375 to 2,025) in the fluid group compared to 0 (IQR 0 to 0) in controls with days in hospital after surgery 12.2 (SD 11.5) days compared to 17.4 (SD 20.0) and an adjusted mean difference of 5.5 days (median 2.2 days; 95% CI -0.44 to 11.44; P = 0.07). There was a reduction in adverse events in the fluid intervention group (P = 0.048) and no increase in fluid based complications. The intervention was less costly and more effective (adjusted average cost saving: £2,047; adjusted average gain in benefit: 0.0431 quality adjusted life year (QALY)) and has a high probability of being cost-effective. Pre-operative intravenous fluid loading leads to a non-significant reduction in hospital length of stay after high-risk major surgery and is likely to be cost-effective. Confirmatory work is required to determine whether these effects are reproducible, and to confirm whether this simple intervention could allow more cost-effective delivery of care.

To investigate anesthesia management in patients undergoing right lung surgery after a previous left upper lobectomy (LUL) that may require special precautions since angulation of the left bronchus can hamper correct placement of a left-sided double-lumen tube (DLT), and one-lung ventilation (OLV) depending solely on the left lower lobe may lead to inadequate oxygenation. A retrospective data analysis. Single university hospital. Patients underwent right lung surgery after previous LUL. None. Anesthesia management was investigated in 18 patients who underwent right lung surgery following LUL. All intubation procedures were performed under bronchoscopic guidance to prevent airway trauma. OLV could be achieved with a left-sided DLT in 12 patients, while tubes other than this were required in 6 patients, including a right-sided DLT (n = 3) and a bronchial blocker (n = 3). The presence or absence of remarkable bronchial angulation, characterized by a combination of a wide (>140°) angle between the trachea and left main bronchus and a narrow (<100°) angle between the left main and lower bronchi critically affected tube selections. The minimum SpO2 during OLV was 90.9±4.1%. In 2 patients, intermittent bilateral ventilation was required to treat desaturation. In all the patients, the scheduled surgery could be completed. Extent of left bronchial angulations had a critical impact on whether or not a left-sided DLT could be used in patients undergoing right lung surgery after LUL. Copyright © 2016 Elsevier Inc.

This study aims to investigate if there is equivalence in volumes of fluid administered when intravenous fluid therapy is guided by Pleth Variability Index (PVI) compared to the established technology of esophageal Doppler in low-risk patients undergoing major colorectal surgery. Randomized controlled trial. Operating room. Forty low-risk patients undergoing elective colorectal surgery. Patients were monitored by esophageal Doppler and PVI probes and were randomized to have fluid therapy directed by using one of these technologies, with 250 mL boluses of colloid to maintain a maximal stroke volume, or a PVI of less than 14%. Absolute volumes of fluid volumes given intraoperatively were measured as were 24 hours fluid volumes. Perioperative measurements of lactate and base excess were recorded as were postoperative complications. There was no significant difference between PVI and esophageal Doppler groups in mean total fluid administered (1286 vs 1520 mL, P=.300) or mean intraoperative fluid balance (+839 v+1145 mL, P=.150). PVI offers an entirely non-invasive alternative for goal-directed fluid therapy in this group of patients. Copyright © 2016 Elsevier Inc. All rights reserved.

To investigate the functional state of the upper urinary tract in patients undergoing autoplastic surgery for a hydronophrosis of the intrarenal pelvis. The study comprised 78 patients with the intrarenal pelvis and impaired urinary outflow due to stricture of the ureteropelvic junction and vascular conflict (interatrial and arteriovenous narrowing), who underwent pyeloplasty using autologous tunica vaginalis. All patients underwent an incision of ureteropelvic stricture and resection of the parietal layer of the tunica vaginalis which was used to repair the obstruction site and internal stenting of the upper urinary tract. The patients were examined at baseline and during follow-up ranging from 3 months to 3 years. At three months after surgery, there was a decrease in the size of the renal pelvis and calyces with an improvement of all parameters of uro- and hemodynamics. At three years after surgery, the structural and functional parameters of the upper urinary tract were completely restored. Obstructive uropathy, resulting from the intrarenal pelvis, leads to persistently impaired urinary outflow from the upper urinary tract. Surgical intervention is the only curative treatment able to restore the urinary flow. In men with the intrarenal pelvis, the autoplastic surgery of the ureteropelvic junction obstruction using a parietal layer of the tunica vaginalis is an effective surgical modality improving renal pelvis capacity and contributing to the recovery of urinary outflow from the upper urinary tract.

The goal of the present study was to evaluate the effects of preoperative oral carbohydrate supplementation (OCH) on the postoperative metabolic stress response of patients undergoing elective abdominal surgery. The study was designed as a controlled, prospective, cohort study including 38 patients treated with OCH (800 mL the day before surgery and 400 mL within 3 h before the induction of anesthesia) and 38 controls matched for surgical procedure. Fasting glucose, insulin, insulin resistance (HOMA-IR index), cortisol, and interleukin 6 (IL-6) were assessed before and after surgery (postoperative day (POD) 1, 2, and 3). The administration of OCH resulted in lower fasting glucose, HOMA-IR index, cortisol, and IL-6 on both POD 1 and POD 2. At multivariable regression analyses, the reduction of these parameters was independent of sex, age, body mass index, and major abdominal surgery. Particularly, models including OCH treatment explained 70, 63, and 66 % of the variance of the increase in IL-6 levels at POD 1, POD 2, and POD 3, respectively. The effect of OCH on changes in glucose, insulin resistance, and cortisol on POD 1 and POD 2 disappeared after the inclusion of IL-6 in the models. Treatment with OCH was associated with attenuation of the postoperative metabolic stress response. We hypothesize that modulation of the inflammatory response is one of the mechanisms involved.

Low-dose haloperidol is known to be effective for the prevention of postoperative nausea and vomiting (PONV). However, precise dose-response studies have not been completed, especially in patients at high risk for PONV who require combination therapy. This study sought to identify which dose of haloperidol 1mg or 2mg could be combined with dexamethasone without adverse effects in high-risk patients undergoing gynecological laparoscopic surgery. Female adults (n = 150) with three established PONV risk factors based on Apfel's score were randomized into one of three study groups. At the end of anesthesia, groups H0, H1, and H2 were given intravenous (IV) saline, haloperidol 1 mg, and haloperidol 2 mg, respectively. All patients were given dexamethasone 5 mg during the induction of anesthesia. The overall early (0-2 h) and late (2-24 h) incidences of nausea, vomiting, rescue anti-emetic administration, pain, and adverse effects (cardiac arrhythmias and extrapyramidal effects) were assessed postoperatively. The sedation score was recorded in the postanesthesia care unit (PACU). The total incidence of PONV over 24 h was significantly lower in groups H1 (29 %) and H2 (24 %) than in group H0 (54 %; P = 0.003), but there was no significant difference between groups H1 and H2. In the PACU, group H2 had a higher sedation score than groups H1 and H0 (P < 0.001). For high-risk PONV patients undergoing gynecological laparoscopic surgery, when used with dexamethasone, 1-mg haloperidol was equally effective as 2 mg in terms of preventing PONV with the less sedative effect.

Abstract: Modified ultrafiltration is an important technique to concentrate the patient’s circulating blood volume and the residual whole blood in the extracorporeal circuit post-cardiopulmonary bypass. The Hemobag system is a device cleared by the US Food and Drug Administration and represents a novel and safe modification of traditional modified ultrafiltration systems. It is quick and easy to operate by the perfusionist during the hemoconcentration process. Hemoconcentration is accomplished by having the Hemobag “recovery loop” circuit separate from the extracorporeal circuit. This allows the surgeons to continue with surgery, decannulate, and administer protamine simultaneously while the Hemobag is in use. The successful use of the Hemobag in a Jehovah’s Witness patient has not been previously described in the literature. This case report describes how to set up and operate the Hemobag in a Jehovah’s Witness patient undergoing cardiac surgery that requires an extracorporeal circuit. PMID:17089515

Once aprotinin was no longer available for clinical use, ε-aminocaproic acid (EACA) and tranexamic acid became the only two options for antifibrinolytic therapy. We compared aprotinin and EACA with respect to their blood-sparing efficacy and other major clinical outcome criteria in infants undergoing cardiac surgery. We retrospectively analysed data from a large consecutive cohort of infants (n=227) aged 31-365 days undergoing primary cardiac surgery requiring cardiopulmonary bypass encompassing the transition from aprotinin to EACA (aprotinin n=88, EACA n=139); all other aspects including the medical team and departmental protocols remained unchanged. The primary outcome was postoperative blood loss measured as chest tube output (CTO). Secondary outcome parameters were transfusion requirements, reoperation due to bleeding, renal, vascular, and neurological complications, and in-hospital mortality. CTO was significantly higher in the EACA patients {aprotinin 18 (13-27) ml kg(-1) 24 h(-1), EACA 23 (15-37) ml kg(-1) 24 h(-1) [mean (inter-quartile range)], P=0.001}, but transfusion requirements and donor exposures were not significantly different. A sensitivity analysis strengthened our finding that the increased blood loss in the EACA group was attributable to lower efficacy of EACA. There were no significant differences in the other clinical outcome measures. CTO was lower in aprotinin-treated patients. Nonetheless, EACA remains a suitable substitute without measurable differences in other clinical outcome criteria.

Normothermic Versus Hypothermic Cardiopulmonary Bypass in Children Undergoing Open Heart Surgery (Thermic-2): Study Protocol for a Randomized Controlled Trial

Background During open heart surgery, patients are connected to a heart-lung bypass machine that pumps blood around the body (“perfusion”) while the heart is stopped. Typically the blood is cooled during this procedure (“hypothermia”) and warmed to normal body temperature once the operation has been completed. The main rationale for “whole body cooling” is to protect organs such as the brain, kidneys, lungs, and heart from injury during bypass by reducing the body’s metabolic rate and decreasing oxygen consumption. However, hypothermic perfusion also has disadvantages that can contribute toward an extended postoperative hospital stay. Research in adults and small randomized controlled trials in children suggest some benefits to keeping the blood at normal body temperature throughout surgery (“normothermia”). However, the two techniques have not been extensively compared in children. Objective The Thermic-2 study will test the hypothesis that the whole body inflammatory response to the nonphysiological bypass and its detrimental effects on different organ functions may be attenuated by maintaining the body at 35°C-37°C (normothermic) rather than 28°C (hypothermic) during pediatric complex open heart surgery. Methods This is a single-center, randomized controlled trial comparing the effectiveness and acceptability of normothermic versus hypothermic bypass in 141 children with congenital heart disease undergoing open heart surgery. Children having scheduled surgery to repair a heart defect not requiring deep hypothermic circulatory arrest represent the target study population.

Patients undergoing cardiac surgery with extracorporeal circulation (ECC) frequently present haemorrhages as a complication associated with high morbidity and mortality. One of the factors that influences this risk is the volume of blood infused during surgery. The objective of this study was to determine the optimal volume of autologous blood that can be processed during cardiac surgery with ECC. We also determined the number of salvaged red blood cells to be reinfused into the patient in order to minimize the risk of haemorrhage in the postoperative period. This was an observational retrospective cross-sectional study performed in 162 ECC cardiac surgery patients. Data regarding the sociodemographic profiles of the patients, their pathologies and surgical treatments, and the blood volume recovered, processed, and reinfused after cell salvage were collected. We also evaluated the occurrence of postoperative haemorrhage. The volume of blood infused after cell salvage had a statistically significant effect (p < 0.01) on the risk of post-operative haemorrhage; the receiver operating characteristic sensitivity was 0.813 and the optimal blood volume cut-off was 1800 ml. The best clinical outcome (16.7% of patients presenting haemorrhages) was in patients that had received less than 1800 ml of recovered and processed autologous blood, which represented a volume of up to 580 ml reinfused red blood cells. The optimum thresholds for autologous processed blood and red blood cells reinfused into the patient were 1800 and 580 ml, respectively. Increasing these thresholds augmented the risk of haemorrhage as an immediate postoperative period complication.
