Effect of Lateral Versus Supine Positions on Postoperative Hypoxemia
Recruiting now · Not applicable
Conditions studied: Postoperative Hypoxemia
In brief
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.
