Prolonged recovery time in the postanesthesia care unit (PACU) increases cost and administrative burden of outpatient surgical staff. The primary aim of this study was to determine whether body mass index (BMI) is associated with prolonged recovery in the PACU after outpatient surgery in a freestanding ambulatory surgery center.We retrospectively studied 3 years of surgeries performed at a freestanding ambulatory surgery center. Mixed-effects logistic (for binary outcomes) and linear (for continuous outcomes) regressions were performed, in which the random effect was the surgical procedure. Prolonged PACU length of stay was modeled as a binary variable, that is, stay greater than the third quartile, and as a continuous variable, that is, actual duration of stay in minutes. We reported odds ratio and 95% confidence interval from the logistic regression and estimates with standard errors from the linear regression.Patients with obesity (BMI ≥ 30 kg/m 2 ) did not demonstrate increased odds for prolonged PACU length of stay (all P0.05). Furthermore, BMI-represented as a continuous variable-was not associated with actual PACU length of stay (estimate = 0.05, standard error = 0.06, P = 0.41). No association was found between obesity and PACU length of stay on a subgroup analysis where only patients with obstructive sleep apnea were analyzed.There was no association between BMI and PACU length of stay among patients who received outpatient surgery at a freestanding ambulatory surgery center.

The rise in obesity in the United States, along with improvements in antiviral therapies, has led to an increase in the number of obese patients receiving liver transplants. Currently, obesity is a relative contraindication for liver transplant, although exact body mass index (BMI) limits continue to be debated. Studies conflict regarding outcomes in obese patients, while some argue that BMI should not be used as an exclusion criterion at all. Therefore, this retrospective study-utilizing a large national database-seeks to elucidate the association between recipient BMI and hospital length of stay and mortality following liver transplant.A retrospective study was conducted using the United Network for Organ Sharing Standard Transplant Analysis and Research database. Fine-Gray competing risk regressions were used to explore the association between BMI and rate of discharge, which varies inversely with length of stay. In our model, subdistribution hazard ratio (SHR) represented the relative change in discharge rate compared to normal BMI, with in-hospital death was considered as a competing event for live discharge. Cox proportional hazard models were built to assess the association of BMI category on all-cause mortality after liver transplantation. Cluster-robust standard errors were used in all analyses to construct confidence intervals.Within the final sample (n = 47,038), overweight (≥25 and30 kg/m2) patients comprised the largest BMI group (34.7%). The competing risk regression model showed an association for increased length of stay among underweight (SHR = 0.82, 95% confidence interval [CI], 0.77-0.89; P.001) and class 3 obesity patients (SHR = 0.88, 95% CI, 0.83-0.94; P.001), while overweight (SHR = 1.05, 95% CI, 1.03-1.08; P.001) and class 1 obesity (SHR = 1.04, 95% CI, 1.01-1.07; P = .01) were associated with decreased length of stay. When the sample excluded patients with low pretransplant functional status, however, length of stay was not significantly shorter for overweight and obesity class 1 patients. Cox proportional hazard models demonstrated increased survival among overweight, class 1 and class 2 obesity patients and decreased survival among underweight patients.Our results provide evidence that overweight and obesity class 1 are associated with decreased length of stay and mortality following liver transplant, while underweight and obesity class 3 are associated with prolonged length of stay. Pretransplant functional status may contribute to outcomes for overweight and class 1 obese patients, which necessitates continued investigation of the isolated impact of BMI in those who have had a liver transplant.

Background Racial and ethnic differences in the use of neuraxial anesthesia compared with general anesthesia are less studied, particularly in obstetrical anesthesia. Here, we aimed to provide an update on the association between race and ethnicity, and the use of neuraxial anesthesia for cesarean delivery in the United States (US). Methods We used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use Data File 2019. We extracted cases that had a primary surgery defined with Current Procedural Terminology (CPT) code for cesarean delivery (59510, 59514, and 59515) and cesarean after attempted vaginal delivery in parturients with a prior history of cesarean (59618, 59620, and 59622). Multivariable logistic regression was used to report the association of race and ethnicity with primary anesthetic technique. Results There were 12,876 parturients included in the study. Compared with White parturients, Black (adjusted odds ratio (aOR) = 0.71, 95% confidence interval (CI): 0.57-0.88, p = 0.001) and American Indian or Alaska Native (aOR = 0.22, 95% CI: 0.12-0.40, p < 0.001) parturients had lower odds of receiving neuraxial compared with general anesthesia. There were no significant differences in the odds of neuraxial anesthesia between non-Hispanic and Hispanic cohorts. Conclusions While we do observe racial differences in anesthetic technique, Hispanic patients did not have significantly lower odds of neuraxial anesthesia. This study highlights the importance of an update to prior studies, as the current study suggests a lack of disparity between non-Hispanic and Hispanic parturients. While the results here are encouraging, a multidisciplinary approach is necessary to further address racial disparities.

PURPOSE OF REVIEW: Nonoperating room anesthesia (NORA) continues to increase in popularity and scope. This article reviews current and new trends in NORA, trends in anesthesia management in nonoperating room settings, and the evolving debates surrounding these trends. RECENT FINDINGS: National data suggests that NORA cases will continue to rise relative to operating room (OR) anesthesia and there will continue to be a shift towards performing more interventional procedures outside of the OR. These trends have important implications for the safety of interventional procedures as they become increasingly more complex and patients continue to be older and more frail. In order for anesthesia providers and proceduralists to be prepared for this future, rigorous standards must be set for safe anesthetic care outside of the OR.Although the overall association between NORA and patient morbidity and mortality remains unclear, focused studies point toward trends specific to each non-OR procedure type. Given increasing patient and procedure complexity, anesthesiology teams may see a larger role in the interventional suite. However, the ideal setting and placement of anesthesia staff for interventional procedures remain controversial. Also, the impact of COVID-19 on the growth and utilization of non-OR anesthesia remains unclear, and it remains to be seen how the pandemic will influence the delivery of NORA procedures in postpandemic settings. SUMMARY: NORA is a rapidly growing field of anesthesia. Continuing discussions of complication rates and mortality in different subspecialty areas will determine the need for anesthesia care and quality improvement efforts in each setting. As new noninvasive procedures are developed, new data will continue to shape debates surrounding anesthesia care outside of the operating room.

Purpose of review As the volume and types of procedures requiring anesthesiologist involvement in the nonoperating room anesthesia (NORA) setting continue to grow, it is important to create a formal curriculum and clearly define educational goals. Recent findings A NORA rotation should be accompanied by a dedicated curriculum that should include topics such as education objectives, information about different interventional procedures, anesthesia techniques and equipment, and safety principles. NORA environment may be unfamiliar to anesthesia residents. The trainees must also learn the principles of efficiency, rapid recovery from anesthesia, and timely room turnover. Resident education in NORA should be an essential component of their training. The goals and objectives of the NORA educational experience should include not only developing the clinical knowledge necessary to implement the specific type of anesthetic desired for each procedure, but also the practical knowledge of care coordination needed to safely and efficiently work in the NORA setting. Summary As educators, we must foster and grow a resident's resilience by continually challenging them with new clinical scenarios and giving them appropriate autonomy to take risks and move outside of their comfort zone. Residents should understand that exposure to such unique and demanding environment can be transformative.

Study objective It is unclear what the body mass index (BMI) should be when performing surgery involving the airway at an outpatient surgery facility. The objective of this study was to evaluate the association of Class 3 obesity versus a composite cohort of Class 1 and 2 obesity with same-day hospital admission following outpatient tonsillectomy in adults. Design Retrospective cohort study. Setting Multi-institutional. Patients Patients undergoing outpatient tonsillectomy. Intervention None. Measurements We used the National Surgical Quality Improvement Program (NSQIP) to analyze association of BMI to same-day admission and 30-day readmission following outpatient tonsillectomy from 2017 to 2019. We looked at six BMI cohorts: 1) ≥30 and Main results There were 12,287 patients included in the final analysis, at which 697 (5.7%) and 283 (2.3%) had a same-day admission or 30-day readmission, respectively. On Poisson regression with robust standard errors, the relative risks for BMI ≥40 kg/m2 and Conclusion These results contribute data that may help practices – especially freestanding ambulatory surgery centers – decide appropriate BMI cutoffs for surgery involving the airway. Whether this is considered clinically significant enough to rule out eligibility will differ from practice-to-practice and will depend on surgical volume, resources available and financial interests.
