Safety and incidence of complications associated with bronchoscopy in an obese population

Introduction The safety of bronchoscopy in obese patients and those with obstructive sleep apnea (OSA) is unclear. Our objective was to evaluate the incidence of complications during bronchoscopy under moderate sedation in obese patients and to assess the impact of OSA, body mass index (BMI), and du...

Description
Summary:Introduction The safety of bronchoscopy in obese patients and those with obstructive sleep apnea (OSA) is unclear. Our objective was to evaluate the incidence of complications during bronchoscopy under moderate sedation in obese patients and to assess the impact of OSA, body mass index (BMI), and duration of the procedure. Methods We performed a retrospective study in adult patients undergoing bronchoscopy from January 2010 to August 2019. All patients with BMI > 30 kg/m2 were included. Logistic regression analyses were used to identify the factors associated with all‐complications and respiratory complications. Results A total of 345 obese patients were identified. The average BMI in our cohort was 35.3 ± 5.1 kg/m2. During the pre‐procedure risk assessment, 165 (47.8%) patients were labelled as “suspected OSA.” The most common doses of sedation given during the bronchoscopies were fentanyl 50 mcg (34.5%) and midazolam 3 mg (33.6%). The incidence of major complications was 0.6% and minor complications were 41.2%. Minor respiratory (22.9%) and cardiac (26.4%) complications were common. No deaths occurred due to bronchoscopy. Factors that were associated with increased respiratory complications were female gender, suspected OSA, and bronchoscopy duration 20‐30 minutes and bronchoscopy duration greater than 1 hour. Conclusion Bronchoscopy under moderate sedation performed in obese patients is safe; however, increased risk may exist with females, increased procedure time, and suspected OSA.
