Effect of Lateral Versus Supine Positions on Postoperative Hypoxemia

China960 participantsStarted 2026-04-23

Plain-language summary

Using prospective real-world data, this study aims to determine whether the lateral decubitus position reduces the incidence of post-procedure hypoxemia in patients undergoing painless gastroscopy/colonoscopy, thereby providing a simple, non-invasive, and low-cost optimization strategy for clinical practice.
