Adverse events in patients with obstructive sleep apnea undergoing procedural sedation in ambulatory settings: An updated systematic review and meta-analysis.

Abstract

Objective: Patients with obstructive sleep apnea (OSA) may be at increased risk for adverse events during procedural sedation, however, there remains a gap in the literature quantifying these risks. This systematic review and meta-analysis aimed to evaluate the risk of peri-procedural adverse events in OSA patients undergoing procedural sedation in ambulatory settings, compared to those without OSA.

Methods: Four databases were systematically searched for studies published from January 1, 2011 to January 4, 2024. The inclusion criteria were: adult patients with OSA undergoing procedural sedation in ambulatory settings, peri-procedural adverse events reported, and control group included. The primary outcome was the incidence of peri-procedural adverse events amongst patients with vs without OSA.

Results: Nineteen studies (27,973 patients) were included. The odds of respiratory adverse events were significantly increased for patients with OSA (OR 1.65, 95 % CI 1.03-2.66, P = 0.04). Furthermore, the odds of requiring an airway maneuver/intervention were significantly greater for patients with OSA (OR 3.28, 95 % CI 1.43-7.51, P = 0.005). The odds of cardiovascular adverse events were not significantly increased for patients with OSA.

Conclusion: Patients with OSA undergoing procedural sedation in ambulatory settings had 1.7-fold greater odds of respiratory adverse events and 3.3-fold greater odds of requiring airway maneuvers/interventions.
