Core Tip

Core tip: Patients with obstructive sleep apnea (OSA) often receive monitored anesthesia care in lieu of conscious sedation due to a perceived elevated risk of complications. However, prior studies have failed to note any clinically significant variations in cardiopulmonary parameters in OSA patients when compared to controls during endoscopy but studies have been underpowered due to small sample sizes. The objective was to perform a systematic review and meta-analysis to assess the safety of conscious sedation in patients with OSA. This meta-analysis showed OSA is not a significant risk factor for cardiopulmonary complications in patients undergoing endoscopic procedures with conscious sedation.
