A prospective randomized controlled trial was conducted to evaluate the impact of patient positioning on respiratory safety, providing evidence for individualized anesthesia management.\n\nBackground:\n\nWith the increasing popularity of painless gastrointestinal endoscopy, hypoxemia has become a major safety concern in anesthesia management, particularly in elderly and obese patients. Studies have shown that the incidence of hypoxemia can exceed 26%, highlighting the importance of optimizing respiratory safety during anesthesia.\n\nMethods:\n\nA total of 400 patients scheduled for painless gastrointestinal endoscopy were recruited and randomly assigned to a control group (0° left lateral position) or an experimental group (15° left lateral position). Baseline data were recorded preoperatively. Intraoperative vital signs were monitored, and the occurrence of hypoxemia and other complications was documented. Data were collected and processed in a blinded manner, followed by statistical analysis using SPSS 26.0.",[44],"Hypoxemia","NOT_YET_RECRUITING","2026-05-18",{"date":48,"type":49},"2026-05-19","ACTUAL",{"date":51,"type":38},"2026-05-01",{"date":53,"type":38},"2026-07-01",{"name":5,"class":6}]
