BACKGROUND: Childhood and adolescent obesity increased in recent decades, and caregivers face an increasing number of obese pediatric surgical patients. Some clinical and pharmacogenetic data suggest that obese patients have altered pain sensitivity and analgesic requirements. OBJECTIVE: To test the primary hypothesis that increased BMI in pediatric patients is associated with increased pain during the initial 48 postoperative hours. Secondarily, we tested whether BMI is associated with increased opioid consumption during the same period. DESIGN: Retrospective single-center cohort study. SETTING: Pediatric surgical wards in a tertiary medical center. PATIENTS: A total of 808 opioid naïve patients aged 8 to 18 years having elective non-cardiac surgery with hospital stay of at least 48 h in the Cleveland Clinic between 2010 and 2015. INTERVENTIONS: None. MEASUREMENTS: Using U.S. Centers for Disease Control definitions for childhood weight classifications, we retrospectively evaluated the association between body mass index (BMI) percentile and time-weighted average pain scores and opioid consumption. We used multivariable linear regression to test for an association with postoperative pain scores, and multivariable gamma regression to test for an association with postoperative opioid consumption (in mg morphine equivalents Kg-1). RESULTS: BMI was not associated with postoperative pain after general, orthopedic, or neuro-spinal surgeries. Pain increased by 0.07 [98.75% CI: (0.01, 0.13), Padj < 0.05] points per 5 percentile increase in BMI after neuro-cranial surgery. Higher BMI was associated with a decrease in postoperative opioid consumption (mean change [95% CI] -2.12% [-3.12%, -1.10%] in morphine equivalents Kg-1 per 5 percentile increase in BMI, P < 0.001). CONCLUSION: We found no clinically important increase in pain scores or opioid consumption in association with higher BMI in patients 8 to 18 years of age recovering from elective non-cardiac surgery.

BACKGROUND: Dexmedetomidine is increasingly used in children undergoing cardiac catheterization procedures. We compared the percentage of surgical time with hemodynamic instability and the incidence of postoperative agitation between pediatric cardiac catheterization patients who received dexmedetomidine infusion and those who did not and the incidence of postoperative agitation. MATERIALS AND METHODS: We matched 653 pediatric patients scheduled for cardiac catheterization. Two separate multivariable linear mixed models were used to assess the association between dexmedetomidine use and intraoperative blood pressure and heart rate instability. A multivariate logistic regression was used for relationship between dexmedetomidine and postoperative agitation. RESULTS: No difference between the study groups was found in the duration of MAP ( P = .867) or heart rate (HR) instabilities ( P = .224). The relationship between dexmedetomidine use and the duration of negative hemodynamic effects does not depend on any of the considered CHD types (all P > .001) or intervention ( P = .453 for MAP and P = .023 for HR). No difference in postoperative agitation was found between the study groups ( P = .590). CONCLUSION: Our study demonstrated no benefit in using dexmedetomidine infusion compared with other general anesthesia techniques to maintain hemodynamic stability or decrease agitation in pediatric patients undergoing cardiac catheterization procedures.

OBJECTIVE: International scientific publication productivity is a tangible indicator for the accuracy of scientific policies. The quality of scientific publications is not increasing despite the fast increase in the publication count in Turkey. The international publication activities of Turkish anaesthesia clinics have not been previously explored. Thus, we aimed to evaluate the high quality scientific productivity of Turkish anesthesia clinics within the last 10 years. METHODS: We searched for studies conducted by anaesthesiologists in Turkey within the last 10 years and published in journals listed under the medical subject categories of anaesthesiology and critical care using 'Thomson Reuters InCites' and PubMed databases. We recorded publication year, subject, method, citation count and origin of each paper and conducted descriptive analyses. RESULTS: There were 630 papers meeting our inclusion criteria. Among those, 525 (83%) were studies on anaesthesia, 66 (10%) were studies on critical care and 39 (6%) were studies on pain. The average citation count was 9.90. There were 376 controlled/randomized controlled trials, 98 observational studies, 66 laboratory studies, 64 case series/reports, 5 reviews and 21 letters to the editor. Studies were conducted by universities (82.4%), by training and research hospitals (15.56%), by state and military hospitals (0.63%) and by physicians in private practice (1.27%). Baskent University had the highest publication count, Istanbul University had the highest citation count and Trakya University had the highest publication count per faculty teaching staff. CONCLUSION: The high-impact scientific productivity of Turkish anesthesia clinics is in a downward trend in the last 10 years, and the average citation count is lower than the global average.

BACKGROUND: Systemic lupus erythematosus (SLE) is a common autoimmune connective tissue disease that mainly harms kidneys, heart, lungs, and nervous system. Effects of surgical stimulus and anesthesia combined with SLE-related pathologies may increase morbidity and mortality. Therefore, we aimed to evaluate the association between SLE (versus none) and postoperative renal, cardiac, and in-hospital mortality complications among patients undergoing major surgeries. METHODS: We obtained censuses of 2009 to 2011 inpatient hospital discharges across 7 states and conducted a retrospective cohort study by using International Classification of Diseases and Injuries, Version 9, diagnosis codes, procedure codes, and present-on-admission indicators. We included patients who had major surgery and matched each SLE discharge up to 4 control discharges for potential confounders. We assessed the association between matched SLE patients and controls on in-hospital renal complications, cardiovascular complications, and in-hospital mortality using separate logistic regression models. RESULTS: Among 8 million qualifying discharges, our sample contained 28,269 SLE patients matched with 13,269 controls. SLE was associated with a significantly higher risk of postoperative renal complications, with an estimated odds ratio (99% CI) of 1.33 (1.21, 1.46); P < .001. In addition, SLE was significantly associated with a higher risk of in-hospital mortality, with an estimated odds ratio (99% CI) of 1.27 (1.11, 1.47); P < .001. However, we found no significant association between SLE and cardiac complications, with an estimated odds ratio (99% CI) of 0.98 (0.83, 1.16), P = .79. CONCLUSIONS: This is, by far, the largest clinical study for postoperative outcomes of SLE patients with adequately powered statistical analyses. We concluded that SLE was associated with a higher risk of renal complications and in-hospital mortality but not cardiac events after major surgery. In SLE patients, more aggressive measures should be taken to prevent renal injury in the perioperative period.

BACKGROUND: Statins may reduce the risk of pulmonary and neurologic complications after cardiac surgery. METHODS: The authors acquired data for adults who had coronary artery bypass graft, valve surgery, or combined procedures. The authors matched patients who took statins preoperatively to patients who did not. First, the authors assessed the association between preoperative statin use and the primary outcomes of prolonged ventilation (more than 24 h), pneumonia (positive cultures of sputum, transtracheal fluid, bronchial washings, and/or clinical findings consistent with the diagnosis of pneumonia), and in-hospital all-cause mortality, using logistic regressions. Second, the authors analyzed the collapsed composite of neurologic complications using logistic regression. Intensive care unit and hospital length of stay were evaluated with Cox proportional hazard models. RESULTS: Among 14,129 eligible patients, 6,642 patients were successfully matched. There was no significant association between preoperative statin use and prolonged ventilation (statin: 408/3,321 [12.3%] vs. nonstatin: 389/3,321 [11.7%]), pneumonia (44/3,321 [1.3%] vs. 54/3,321 [1.6%]), and in-hospital mortality (52/3,321 [1.6%] vs. 43/3,321 [1.3%]). The estimated odds ratio was 1.06 (98.3% CI, 0.88 to 1.27) for prolonged ventilation, 0.81 (0.50 to 1.32) for pneumonia, and 1.21 (0.74 to 1.99) for in-hospital mortality. Neurologic outcomes were not associated with preoperative statin use (53/3,321 [1.6%] vs. 56/3,321 [1.7%]), with an odds ratio of 0.95 (0.60 to 1.50). The length of intensive care unit and hospital stay was also not associated with preoperative statin use, with a hazard ratio of 1.04 (0.98 to 1.10) for length of hospital stay and 1.00 (0.94 to 1.06) for length of intensive care unit stay. CONCLUSIONS: Preoperative statin use did not reduce pulmonary or neurologic complications after cardiac surgery.
