Many children recovering from anesthesia experience pain that is severe enough to warrant intravenous (IV) opioid treatment within moments of admission to the postanesthesia care unit (PACU). Postoperative pain has several negative consequences; therefore, preventing significant PACU pain in children is both a major clinical goal and a moral/ethical imperative. This requires identifying patient-level and perioperative factors that may be used to predict PACU IV opioid requirement. This should allow for the development of personalized care protocols to prevent clinically significant PACU pain in children. Our objective was to develop prediction models enabling practitioners to identify children at risk for PACU IV opioid requirement after various painful ambulatory surgical procedures.After Institutional Review Board approval, clinical, demographic, and anthropometric data were prospectively collected on 1256 children 4-17 years of age scheduled for painful ambulatory surgery (defined as intraoperative administration of analgesia or local anesthetic infiltration). Three multivariable logistic regression models to determine possible predictors of PACU IV opioid requirement were constructed based on (1) preoperative history; (2) history + intraoperative variables; and (3) history + intraoperative variables + PACU variables. Candidate predictors were chosen from readily obtainable parameters routinely collected during the surgical visit. Predictive performance of each model was assessed by calculating the area under the respective receiver operating characteristic curves.Overall, 29.5% of patients required a PACU IV opioid, while total PACU analgesia requirement (oral or IV) was 41.1%. Independent predictors using history alone were female sex, decreasing age, surgical history, and non-Caucasian ethnicity (model area under the receiver operating characteristic curve [AUROC], 0.59 [95% confidence interval {CI}, 0.55-0.63]). Adding a few intraoperative variables improved the discriminant ability of the model (AUROC for the history + intraoperative variables model, 0.71 [95% CI, 0.67-0.74]). Addition of first-documented PACU pain score produced a substantially improved model (AUROC, 0.85 [95% CI, 0.82-0.87]).Postoperative pain requiring PACU IV opioid in children may be determined using a small set of easily obtainable perioperative variables. Our models require validation in other settings to determine their clinical usefulness.

Postoperative delirium is an important public health concern without effective prevention strategies. This study tested the hypothesis that perioperative epidural use would be associated with decreased risk of delirium through postoperative day 3.This was a secondary, observational, nonrandomized analysis of data from The Prevention of Delirium and Complications Associated With Surgical Treatments Trial (PODCAST; NCT01690988). The primary outcome of the current study was the incidence of delirium (ie, any positive delirium screen, postanesthesia care unit through postoperative day 3) in surgical patients (gastrointestinal, hepatobiliary-pancreatic, gynecologic, and urologic) receiving postoperative epidural analgesia compared to those without an epidural. As a secondary outcome, all delirium assessments were then longitudinally analyzed in relation to epidural use throughout the follow-up period. Given the potential relevance to delirium, postoperative pain, opioid consumption, sleep disturbances, and symptoms of depression were also analyzed as secondary outcomes. A semiparsimonious multivariable logistic regression model was used to test the association between postoperative epidural use and delirium incidence, and generalized estimating equations were used to test associations with secondary outcomes described. Models included relevant covariates to adjust for confounding.In total, 263 patients were included for analysis. Epidural use was not independently associated with reduced delirium incidence (adjusted odds ratio, 0.65 [95% CI, 0.32-1.35]; P = .247). However, when analyzing all assessments over the follow-up period, epidural patients were 64% less likely to experience an episode of delirium (adjusted odds ratio, 0.36 [95% CI, 0.17-0.78]; P = .009). Adjusted pain scores (visual analog scale, 0-100 mm) were significantly lower in the epidural group on postoperative day 1 (morning, -16 [95% CI, -26 to -7], P.001; afternoon, -15 [95% CI, -25 to -5], P.01) and postoperative day 3 (morning, -13 [95% CI, -20 to -5], P.01). Adjusted mean oral and IV morphine equivalents were also significantly lower on postoperative day 1 in the epidural group (74% lower [95% CI, 55%-85%]; P.0001). Finally, postoperative epidural use was not significantly associated with new sleep disturbances or changes in depression symptoms.Postoperative epidural use was not associated with a reduced overall incidence of delirium. However, longitudinal analysis revealed reduced adjusted odds of experiencing an episode of delirium in the epidural group. Epidural use was also associated with reduced postoperative pain and opioid consumption. An appropriately designed follow-up study is warranted to further analyze the relationship among epidural use, postoperative delirium, and related outcomes.

We analyzed CBCL/1½−5 Pervasive Developmental Problems (DSM-PDP) scores in 3- to 5-year-olds from the Study to Explore Early Development (SEED), a multi-site case control study, with the objective to discriminate children with ASD (N = 656) from children with Developmental Delay (DD) (N = 646), children with Developmental Delay (DD) plus ASD features (DD-AF) (N = 284), and population controls (POP) (N = 827). ASD diagnosis was confirmed with the ADOS and ADI-R. With a cut-point of T ≥ 65, sensitivity was 80% for ASD, with specificity varying across groups: POP (0.93), DD-noAF (0.85), and DD-AF (0.50). One-way ANOVA yielded a large group effect (η(2) = 0.50). Our results support the CBCL/1½−5’s as a time-efficient ASD screener for identifying preschoolers needing further evaluation.

Purpose Despite growing evidence supporting the potential benefits of higher end-tidal carbon dioxide (ETCO2) levels in surgical patients, there is still insufficient data to formulate guidelines for ideal intraoperative ETCO2 targets. As it is unclear which intraoperative ETCO2 levels are currently used and whether these levels have changed over time, we investigated the practice pattern using the Multicenter Perioperative Outcomes Group database. Methods This retrospective, observational, multicentre study included 317,445 adult patients who received general anesthesia for non-cardiothoracic procedures between January 2008 and September 2016. The primary outcome was a time-weighted average area-under-the-curve (TWA-AUC) for four ETCO2 thresholds (< 28, < 35, < 45, and > 45 mmHg). Additionally, a median ETCO2 was studied. A Kruskal-Wallis test was used to analyse differences between years. Random-effect multivariable logistic regression models were constructed to study variability. Results Both TWA-AUC and median ETCO2 showed a minimal increase in ETCO2 over time, with a median [interquartile range] ETCO2 of 33 [31.0–35.0] mmHg in 2008 and 35 [33.0–38.0] mmHg in 2016 (P

The effect of neither transfusion guidelines nor decision support tools on intraoperative transfusion has been previously evaluated. The University of Michigan introduced a transfusion guideline in 2009, and in 2011, the Department of Anesthesiology developed a transfusion decision support tool. The primary aim of this study was to assess the associations of the transfusion guideline and the optional use of the software transfusion tool with intraoperative behaviors; pretransfusion hematocrit assessment (whether or not a hematocrit was checked before each red cell unit) and restrictive red cell use (withholding transfusion unless the hematocrit was ≤21%).This was a before-after retrospective study without a concurrent control group of patients transfused 1-3 units of red cells intraoperatively. Three phases were studied to provide data both before and after the implementation of the transfusion guideline and the intraoperative software tool. Within each phase, trends of checking hematocrits before transfusion and restrictive transfusion were charted against time. F tests were used to measure differences of slopes. The difference between means of each phase was measured using Mann-Whitney U tests. Independent associations were measured using mixed-effects multivariable logistic regression. A secondary outcome analysis was conducted for 30-day mortality, myocardial infarction, renal injury, and their combination.The transfusion guideline was associated with increased pretransfusion hematocrit evaluation (67.4%, standard deviation [SD] 3.9 vs 76.5%, SD 2.7; P.001) and restrictive transfusion practice (14.0%, SD 7.4 vs 33.3%, SD 4.4; P = .001). After adjustment for confounders, the guideline phase was independently associated with increased hematocrit checking (odds ratio, 1.72; 95% confidence interval, 1.46-2.03; P.001) and restrictive red cell transfusion (odds ratio, 2.95; 95% confidence interval, 2.46-3.54; P.001). The software tool was not associated with either transfusion behavior. There was no significant change in the rate of renal injury (16.06%), myocardial injury (4.93%), 30-day mortality (5.47%), or a composite (21.90%).The introduction of a transfusion guideline was independently associated with increased intraoperative pretransfusion hematocrit assessment and restrictive transfusion. The use of a software tool did not further influence either behavior.

We examined associations between child body mass index at 2–5 years and maternal pre-pregnancy body mass index, gestational weight gain, and rapid weight gain during infancy in children with autism spectrum disorder, developmental delays, or population controls. The Study to Explore Early Development is a multi-site case–control study of children, aged 2–5 years, classified as autism spectrum disorder ( n = 668), developmental delays ( n = 914), or population controls ( n = 884). Maternal gestational weight gain was compared to the Institute of Medicine recommendations. Rapid weight gain was a change in weight-for-age z-scores from birth to 6 months > 0.67 standard deviations. After adjusting for case status, mothers with pre-pregnancy overweight/obesity were 2.38 times (95% confidence interval: 1.96–2.90) more likely, and mothers who exceeded gestational weight gain recommendations were 1.48 times (95% confidence interval: 1.17–1.87) more likely, to have an overweight/obese child than other mothers ( P

Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Perioperative controlled substance diversion and tracking have received increased regulatory focus throughout the United States. The authors’ institution developed and implemented an automated web-based software application for perioperative controlled substance management. The authors hypothesized that implementation of such a system reduces errors as measured by missing controlled substance medications, missing controlled substance kits (a package of multiple controlled substance medications), and missing witness signatures during kit return. Methods From December 1, 2014 to March 31, 2017, the authors obtained missing controlled substance medication, controlled substance kit, and witness return signature data during the preimplementation, implementation, and study period of the controlled substance management application at a single university hospital. This before and after study was based on a QI project at the authors’ institution. The authors included all cases requiring anesthesia services. The primary outcome of this study was the rate of missing controlled substance medications. Secondary outcomes included rates for kits not returned to pharmacy and missing kit return witness signatures. Results There were 54,302 cases during the preimplementation period, 57,670 cases during the implementation period, and 65,911 cases during the study period. The number of missing controlled substance medication (difference 0.7 per 1,000 cases; 95% CI, 0.38–1.02; P < 0.001) and kit return errors (difference 0.45 per 1,000 cases; 95% CI, 0.24–0.66, P < 0.001) declined after implementation of the application. There was no difference in the number of missing witness return signatures (difference 0.09 per 1,000 cases; 95% CI, −0.08 to 0.26, P = 0.350). A user survey with 206 of 485 (42%) response rate demonstrated that providers believed the new application managed controlled substances better than the previous system. Conclusions A software application that tracks perioperative controlled substance kits with deep integration into the electronic health record and pharmacy systems is associated with a decrease in management errors.

Drug shortages negatively affect patient care and outcomes. Postoperative nausea and vomiting (PONV) can be mitigated using risk assessment and prophylaxis. A 2012 propofol shortage provided an opportunity to study the impact of using prophylactic antiemetics and changing the technique from a propofol infusion to inhaled agents in an ambulatory surgery setting. We retrospectively collected data for 2,090 patients regarding PONV risk factors, anesthetic management, and PONV outcomes for periods before, during, and after the shortage. Patients during the propofol shortage experienced a higher incidence of PONV (11% vs 5% before the shortage), greater need for rescue antiemetics (3% vs 1%), and longer duration of stay (mean [SD] = 124 [115] minutes vs 118 [108] minutes). More patients in this group reported PONV at home (14% vs 7%), and 2 required unplanned admission or return to the hospital. During the shortage, patients had a 2-fold increase in the odds of PONV when adjusted for all risk factors. Antiemetics moderated the association between gender and PONV but did not change the effect of the shortage. Findings suggest that despite mitigation efforts, the inability to use propofol infusion was associated with worse PONV outcomes.

BACKGROUND: The objective of this study was to test whether postoperative electroencephalographic biomarkers, parietal alpha power and frontal-parietal connectivity, were associated with measures of clinical recovery in adult surgical patients. METHODS: This is a secondary analysis of a prospective cohort study that analyzed intraoperative connectivity patterns in adult surgical patients (n=53). Wireless, whole-scalp electroencephalographic data were collected in the postanesthesia care unit and assessed for relevance to clinical and neurocognitive recovery. Parietal alpha power and frontal-parietal connectivity (estimated via weighted phase lag index) were tested for associations with postanesthesia care unit discharge readiness and University of Michigan Sedation Scale scores upon postoperative admission. Bivariable correlation and regression models were constructed to test for unadjusted associations, then multivariable regression models were constructed to adjust for confounding. RESULTS: Postoperative electroencephalographic patterns were characterized by a predominance of alpha parietal power and frontal-parietal connectivity. Neither relative parietal alpha power (% alpha, −0.25, 95% CI, −1.41 to 0.90; P=0.657) nor alpha frontal-parietal connectivity (weighted phase lag index, −82, 95% CI, −237 to 73; P=0.287) were associated with time until postanesthesia discharge criteria were met. Furthermore, neither alpha power (−0.03, 95% CI, −0.07 to 0.01; P=0.206) nor alpha frontal-parietal connectivity (−4.2, 95% CI, −11 to 2.6; P=0.226) were associated with sedation scores upon initial assessment. CONCLUSIONS: In a pragmatic study investigating clinically relevant endpoints of postoperative recovery, we found no correlation with surrogate measures of brain neurodynamics. These data contribute to the overall impetus of developing anesthetic-invariant and generalizable markers of brain recovery.

BACKGROUND Unconscious racial bias in anesthesia care has been shown to exist. We hypothesized that black children may undergo inhalation induction less often, receive less support from child life, have fewer opportunities to have a family member present for induction, and receive premedication with oral midazolam less often. METHODS We retrospectively collected data on those

Background Perioperative hyperglycemia is associated with poor outcomes yet evidence to guide intraoperative goals and treatment modalities during non-cardiac surgery are lacking. End-stage liver disease is associated with altered glucose homeostasis; patients undergoing liver transplantation display huge fluctuations in blood glucose (BG) and represent a population of great interest. Here, we conduct a randomized trial to compare the effects of strict versus conventional glycemic control during orthotopic liver transplant (OLT). Methods Following approval by the Institutional Review Board of the University of Michigan Medical School and informed consent, 100 adult patients undergoing OLT were recruited. Patients were randomized to either strict (target BG 80–120 mg/dL) or conventional (target BG 180–200 mg/dL) BG control with block randomization for diabetic and nondiabetic patients. The primary outcomes measured were 1-year patient and graft survival assessed on an intention to treat basis. Graft survival is defined as death or needing re-transplant (www.unos.org). Three and 5-year patient and graft survival, infectious and biliary complications were measured as secondary outcomes. Data were examined using univariate methods and Kaplan-Meir survival analysis. A sensitivity analysis was performed to compare patients with a mean BG of ≤120 mg/dL and those > 120 mg/dL regardless of treatment group. Results There was no statistically significant difference in patient survival between conventional and strict control respectively;1 year, 88% vs 88% (p-0.99), 3 years, 86% vs 84% (p- 0.77), 5 years, 82% vs 78. % (p-0.36). Graft survival was not different between conventional and strict control groups at 1 year, 88% vs 84% (p-0.56), 3 years 82% vs 76% (p-0.46), 5 years 78% vs 70% (p-0.362). Conclusion There was no difference in patient or graft survival between intraoperative strict and conventional glycemic control during OLT. Trial registration Clinical trial number and registry: www.clinicaltrials.gov NCT00780026. This trial was retrospectively registered on 10/22/2008.

Objectives/Hypothesis Local anesthetic with epinephrine is commonly injected into the nasal mucosa during functional endoscopic sinus surgery (FESS). Systemic absorption of epinephrine following local injection may occur, resulting in a mild sympathetic response. This study seeks to determine whether an exaggerated sympathetic response to epinephrine is demonstrated in patients undergoing FESS treated preoperatively with established pharmacologic beta (β) adrenoceptor blockade. Study Design A retrospective analysis of adult patients undergoing FESS at a tertiary care university hospital. Methods The primary outcome was the occurrence of an exaggerated hypertensive response within the first hour of surgical time defined by a relative increase (>20%) in the first measured intraoperative systolic blood pressure (SBP) prior to induction of anesthesia, or a single SBP value above 200 mm Hg. A mixed effects logistic regression model was developed to identify independent predictors of an exaggerated hypertensive response and describe the variance in the outcome attributable to the surgeon and anesthesiologist. Results There were 2,051 patients identified. Independent predictors of an exaggerated intraoperative hypertensive event included: preoperative β-blocker use (adjusted odds ratio [AOR]: 3.33), female gender (AOR: 1.92), body mass index (AOR: 1.03), lower baseline SBP (AOR: 0.93), and advanced age (AOR: 1.03). The C statistic for the model was 0.8881. Conclusions Preoperative β-blocker use is an independent predictor of an exaggerated hypertensive response within the first hour of operative time. An exaggerated hypertensive effect should be anticipated in patients presenting for FESS with established pharmacologic β-blockade, and caution should be applied to use of epinephrine-containing solutions.

Background Assessment of need for intravascular volume resuscitation remains challenging for anesthesiologists. Dynamic waveform indices, including systolic and pulse pressure variation, are demonstrated as reliable measures of fluid responsiveness for mechanically ventilated patients. Despite widespread use, real-world reference distributions for systolic and pulse pressure variation values have not been established for euvolemic intraoperative patients. The authors sought to establish systolic and pulse pressure variation reference distributions and assess the impact of modifying factors. Methods The authors evaluated adult patients undergoing general anesthetics for elective noncardiac surgery. Median systolic and pulse pressure variations during a 50-min postinduction period were noted for each case. Modifying factors including body mass index, age, ventilator settings, positioning, and hemodynamic management were studied via univariate and multivariable analyses. For systolic pressure variation values, effects of data entry method (manually entered vs. automated recorded) were similarly studied. Results Among 1,791 cases, per-case median systolic and pulse pressure variation values formed nonparametric distributions. For each distribution, median values, interquartile ranges, and reference intervals (2.5th to 97.5th percentile) were, respectively, noted: these included manually entered systolic pressure variation (6.0, 5.0 to 7.0, and 3.0 to 11.0 mmHg), automated systolic pressure variation (4.7, 3.9 to 6.0, and 2.2 to 10.4 mmHg), and automated pulse pressure variation (7.0, 5.0 to 9.0, and 2.0 to 16.0%). Nonsupine positioning and preoperative β blocker were independently associated with altered systolic and pulse pressure variations, whereas ventilator tidal volume more than 8 ml/kg ideal body weight and peak inspiratory pressure more than 16 cm H2O demonstrated independent associations for systolic pressure variation only. Conclusions This study establishes real-world systolic and pulse pressure variation reference distributions absent in the current literature. Through a consideration of reference distributions and modifying factors, the authors’ study provides further evidence for assessing intraoperative volume status and fluid management therapies.

The relationship between sleep duration and obesity in adolescents is inconclusive. This may stem from a more complex relationship between sleep and obesity than previously considered. Shifts toward evening preferences, later sleep-wake times and irregular sleep-wake patterns are typical during adolescence but their relationship to body mass index (BMI) has been relatively unexplored. This cross-sectional study examined associations between sleep duration, midpoint of sleep and social jet lag (estimated from 7 days of continuous actigraphy monitoring), and morningness/eveningness with BMIs (BMI z-scores) and waist-to-height ratios in 14-17-year-old adolescents. Seventy participants were recruited from ninth and tenth grades at a public high school. Participants' characteristics were as follows: 74% female, 75% post-pubertal, 36% Hispanic, 38% White, 22% Black, 4% Asian and 64% free/reduced lunch participants with a mean age of 15.5 (SD, 0.7). Forty-one percent of the participants were obese (BMI ≥ 95th percentile); 54% were abdominally obese (waist-to-height ratio ≥ 0.5). Multivariable general linear models were used to estimate the association between the independent variables (school night sleep duration, free night sleep duration, midpoint of sleep (corrected), social jet lag and morningness/eveningness) and the dependent variables (BMI z-scores and waist-to-height ratios). Social jet lag is positively associated with BMI z-scores (p < 0.01) and waist-to-height ratios (p = 0.01). Midpoint of sleep (corrected) is positively associated with waist-to-height ratios (p = 0.01). After adjusting for social jet lag, school night sleep duration was not associated with waist-to-height ratios or BMI z-scores. Morningness/eveningness did not moderate the association between sleep duration and BMI z-scores. Findings from this study suggest that chronobiological approaches to preventing and treating obesity may be important for accelerating progress in reducing obesity rates in adolescents.

External laryngeal trauma is a rare but potentially fatal event that presents several management challenges. This retrospective observational case series conducted at a level-1 trauma center over a 12-year period consists of 62 cases of acute external laryngeal trauma. Patient demographics, mode and mechanisms of injury, presenting signs and symptoms, initial imaging results, airway management, time to surgical management, and 6-month outcomes including airway status, deglutition status, and voice quality were investigated. No difference was found in mortality or 6-month outcomes between patients requiring surgical repair and/or tracheostomy versus patients with less severe injuries managed conservatively.

Objective To assess contributing factors to increased obesity risk, by comparing children with autism spectrum disorder (ASD), developmental delays/disorders, and general population controls in weight status, and to examine associations between weight status and presence of co-occurring medical, behavioral, developmental, or psychiatric conditions across groups and ASD severity among children with ASD. Study design The Study to Explore Early Development is a multisite cross-sectional study of children, 2-5 years of age, classified as children with ASD (n = 668), children with developmental delays/disorders (n = 914), or general population controls (n = 884). Using an observational cohort design, we compared the 3 groups. Children's heights and weights were measured during a clinical visit. Co-occurring conditions (medical, behavioral, developmental/psychiatric) were derived from medical records, interviews, and questionnaires. ASD severity was measured by the Ohio State University Global Severity Scale for Autism. Results The odds of overweight/obesity were 1.57 times (95% CI 1.24-2.00) higher in children with ASD than general population controls and 1.38 times (95% CI 1.10-1.72) higher in children with developmental delays/disorders than general population controls. The aORs were elevated for children with ASD after controlling for child co-occurring conditions (ASD vs general population controls: aOR = 1.51; 95% CI 1.14-2.00). Among children with ASD, those with severe ASD symptoms were 1.7 times (95% CI 1.1-2.8) more likely to be classified as overweight/obese compared with children with mild ASD symptoms. Conclusions Prevention of excess weight gain in children with ASD, especially those with severe symptoms, and in children with developmental delays/disorders represents an important target for intervention.

Sleep is a complex behavior with numerous health implications. Identifying sociodemographic and behavioral characteristics of sleep is important for determining those at greatest risk for sleep-related health disparities. In this cross-sectional study, general linear models were used to examine sociodemographic and behavioral characteristics associated with sleep duration, chronotype, and social jet lag in adolescents. One hundred and fifteen participants completed Phase I (self-reported sleep measures), and 69 of these participants completed Phase II (actigraphy-estimated sleep measures). Black adolescents had shorter free night sleep than Hispanics. Youth with later chronotypes ate fewer fruits and vegetables, drank more soda, were less physically active, and took more daytime naps. Based on these findings, recommendations for individual support and school policies are provided.

PURPOSE Caring for children with autism spectrum disorder (ASD) can be highly demanding and can put significant strain on caregivers. To date, little is known about the extent to which caregivers of children with ASD experience increased levels of stress which may adversely affect health outcomes. The purpose of this secondary analysis was to compare caregivers of children with ASD and caregivers of typically developing children (TDC) in weight status, diet quality, perceived stress related to the parenting role, and functional health and well-being. DESIGN AND METHODS Caregivers of 25 children with ASD and 30 TDC completed the 2005 Block Food Frequency Questionnaire, the 36-item Short Form of the Parenting Stress Index (PSI/SF), and the Short Form Health Survey (SF-36) and had their heights and weights measured during an onsite visit. Diet quality was assessed using the Healthy Eating Index (HEI)-2010 and its dietary components and conformance to the 2010 Dietary Guidelines for Americans. RESULTS ASD caregivers did not differ significantly from TDC caregivers in body mass index or overweight/obesity prevalence (p ≥ .28), even when controlling for covariates. In univariate analyses, ASD caregivers consumed significantly fewer empty calories from solid fats, alcohol, and added sugars than TDC caregivers (p = .03), but they did not differ significantly in any other dietary outcomes including nutrient adequacy (p ≥ .10) and mean total HEI scores (p = .20). ASD caregivers, when compared to TDC caregivers, reported significantly greater parenting stress for the subscales difficult child and parent-child dysfunctional interaction as well as total stress (p

Obstructive sleep apnea (OSA) is a prevalent condition that is associated with early postoperative respiratory complications (PRCs). As the majority of patients with OSA are undiagnosed, preoperative screening remains the most efficient method to identify suspected OSA.This retrospective study was performed on patients undergoing anesthesia in a single academic medical center. We assigned OSA risk class retrospectively to all patients in the study by using the Perioperative Sleep Apnea Prediction (PSAP) score. We evaluated the relationship between PSAP categories and early postoperative invasive airway placement after adjusting for several preoperative and intraoperative factors (including surgical risk) previously associated with PRC occurrence.A total of 108,479 patients were included in the final analysis with an incidence of PRC was 0.3% (n = 280). High PSAP score was associated with postoperative intubation (adjusted odds ratio, 2.3; 95% confidence interval, 1.5-3.7). Several risk factors reflecting anesthetic agents, neuromuscular blocking agents, and opioids were also independently associated with early PRC.We report that suspected OSA based on the PSAP score is independently associated with increased risk of early PRC. Specific anesthetic agents are independently associated with early PRC, pointing to the potential for examining risk modification through these exposures in future studies.

Objective To report survival for patients who undergo urinary diversion for benign indications and to identify risk factors for morbidity at 90 days. Methods This is a retrospective review of consecutive urinary diversions with or without cystectomy for non-oncological indications at a single institution. The indication for diversion was intractable incontinence, upper tract deterioration, urinary fistula, and unmanageable bladder pain. Patients were categorized according to their most severe complication within 90 days of surgery, using the Clavien-Dindo system. Multivariable analysis was performed to identify factors associated with high-grade complications. Survival analysis was performed. Results Between 2007 and 2014, 141 patients underwent urinary diversion for non-oncological indications. The postoperative rate of high-grade adverse events (class III or greater) was 28%. Risk factors for class III or greater complications at 90 days included prolonged intraoperative mean arterial pressure below 75% of baseline, operative duration greater than 343 minutes, and postoperative vasopressor requirement. Kaplan-Meier survival analysis demonstrated a 1- and 5-year survival of 88.4% and 77.2%, respectively. The long-term survival of patients who experienced higher-grade complications was not statistically different from the survival of the rest of the group. The study was limited by a retrospective design and sample size in identifying additional variables associated with increased risk of long-term mortality. Conclusion Urinary diversion for non-oncological conditions has a good 5-year survival in this cohort. Extended case duration and hemodynamic instability during or immediately after urinary diversion are associated with a high-grade complication within 90 days of the procedure.

INTRODUCTION:The clinical importance of postoperative episodic hypoxemia is still unclear, and therefore largely under-studied. As a result, there is limited understanding of its relationship with early postoperative respiratory complications (PRC, defined as intubation within three days of surgery) and hospital resource utilization. MATERIALS AND METHODS:This single center study was performed using a retrospective observational design. We described population based definitions of desaturation from continuous SpO2 monitoring data captured in the post anesthesia care unit (PACU), namely median SpO2 in PACU, duration of desaturation below median, nadir desaturation, and length of oxygen therapy relative to PACU duration. These measures were evaluated against the occurrence of early PRC in logistic regression models. Measures that were independently associated with early PRC were accepted as the primary study exposures. Stratified logistic regression models were planned if significant interaction occurred with high risk surgical procedures. Models were adjusted by including several patient conditions, procedural, and anesthesia risk factors. Propensity matching on desaturation occurrence was planned to evaluate the relationship with postoperative resource utilization. RESULTS:Among 125,740 patients included in the univariate analyses, 351 patients (0.3%) developed early PRC. Nadir desaturation 60 min) to 3.04 (>90 min); p

Local anesthetic with epinephrine is commonly injected into the nasal mucosa during functional endoscopic sinus surgery (FESS). Systemic absorption of epinephrine following local injection may occur, resulting in a mild sympathetic response. This study seeks to determine whether an exaggerated sympathetic response to epinephrine is demonstrated in patients undergoing FESS treated preoperatively with established pharmacologic beta (β) adrenoceptor blockade.A retrospective analysis of adult patients undergoing FESS at a tertiary care university hospital.The primary outcome was the occurrence of an exaggerated hypertensive response within the first hour of surgical time defined by a relative increase (20%) in the first measured intraoperative systolic blood pressure (SBP) prior to induction of anesthesia, or a single SBP value above 200 mm Hg. A mixed effects logistic regression model was developed to identify independent predictors of an exaggerated hypertensive response and describe the variance in the outcome attributable to the surgeon and anesthesiologist.There were 2,051 patients identified. Independent predictors of an exaggerated intraoperative hypertensive event included: preoperative β-blocker use (adjusted odds ratio [AOR]: 3.33), female gender (AOR: 1.92), body mass index (AOR: 1.03), lower baseline SBP (AOR: 0.93), and advanced age (AOR: 1.03). The C statistic for the model was 0.8881.Preoperative β-blocker use is an independent predictor of an exaggerated hypertensive response within the first hour of operative time. An exaggerated hypertensive effect should be anticipated in patients presenting for FESS with established pharmacologic β-blockade, and caution should be applied to use of epinephrine-containing solutions.4.

INTRODUCTION AND OBJECTIVES: Radical cystectomy (RC) represents the standard of care for muscle-invasive and high-risk non-muscle invasive bladder cancer. However, RC is associated with a high complication rate, including perioperative infection. In addition to causing patient morbidity, infections have been identified as a quality metric. Herein, we evaluated the incidence, risk factors, and timing of infection following RC. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried to identify patients undergoing RC for bladder cancer from 2005-2013 using CPT procedure and ICD-9 diagnosis codes. Characteristics including age, gender, body-mass index (BMI), diabetes, smoking status, renal function, steroid usage, albumin, perioperative blood transfusion (PBT), and operative time were assessed for their independent association with the risk of infection (inclusive of urinary tract infection (UTI), surgical site infection (SSI), and sepsis) within 30 days of RC using multivariable logistic regression. RESULTS: A total of 3,187 patients were identified, of whom 2,604 (81.8%) were male. Median age was 70 years (IQR 62, 77). Infection within 30 days of RC was diagnosed in 766 (24%) patients, at a median of 13 days (IQR 8, 19) after RC. The most common infections were SSI (404; 12.7%) and sepsis (405; 12.7%), followed by UTI (309; 9.7%). On multivariable analysis (Table), factors significantly associated with an increased risk of postoperative infection were BMI 30 (OR 1.52; p
