Body Mass Index (BMI) Impact on Anesthetic Safety among Adolescents Undergoing Bilateral Reduction Mammaplasty

Abstract

Introduction:. Obesity is common in adolescents with macromastia seeking surgery, prompting concerns over anesthesia-related complications due to obesity. This may lead to weight-based surgical policies, despite limited research. This study’s purpose is to examine the impact of obesity status on perioperative anesthetic-related adverse events/surgical complications in adolescents/young adults undergoing bilateral reduction mammaplasty. Methods:. A medical record query was performed to retrospectively identify patients who underwent bilateral reduction mammaplasty at our institution between January 2021 and December 2021. Patient demographics and clinical/surgical data were obtained from medical records. Pearson’s chi-square, Fisher exact, and Median tests were used to examine associations between body mass index (BMI) category and clinical/demographic data. Results:. Two hundred patients were included in analyses, with a median age at surgery of 18.0 years. The majority of patients were obese (63.5%, n = 127), and none were underweight. The most common comorbidity was asthma (27.0%, n = 54). There were no anesthetic-related intraoperative complications or delayed waking. The following did not significantly differ by BMI category: proportion of patients who experienced oxygen desaturation (pre-, intra-, or postoperatively), frequency of postoperative complications, and length of postanesthesia care unit and total hospital stays (P > 0.05, all). Conclusions:. While institutions may implement weight-based surgical policies due to anesthesia-related complication concerns in patients with obesity, our study showed that BMI category did not significantly impact anesthetic-related adverse events/surgical complications in our sample. This suggests that such policies are not warranted in all situations, and that decisions regarding their necessity be data-driven.
