简要总结
The goal of this clinical trial is to learn which positioning strategy works better to prevent postoperative hypoxemia in surgical patients: semirecumbent positioning or lateral positioning. It will also learn about the safety and effectiveness of these two positioning approaches. The main questions it aims to answer are:
Does semirecumbent positioning reduce the incidence of postoperative hypoxemia more effectively than lateral positioning? Does lateral positioning reduce the incidence of postoperative hypoxemia more effectively than semirecumbent positioning? What are the differences in patient comfort and recovery outcomes between these two positioning strategies? Researchers will compare semirecumbent positioning directly to lateral positioning to see which approach is more effective in preventing postoperative hypoxemia.
Participants will:
Be randomly assigned to either semirecumbent positioning or lateral positioning after surgery Have their oxygen levels and breathing monitored regularly during the postoperative period Receive standard post-surgical care with their assigned positioning strategy Be assessed for comfort levels and any positioning-related complications Have their recovery progress tracked throughout their hospital stay.

研究组 & 干预措施
Semirecumbent positioning
Patients in the Semirecumbent positioning were placed in the bed and the head of the bed was raised by 30 °, allowing flexibility based on patient comfort and surgical requirements.
干预措施: Semirecumbent positioning (Behavioral)
Lateral positioning
Patients allocated to lateral positioning were placed at 90° on a horizontal bed, supported with a pillow to maintain neutral alignment of the spine and avoid hyperextension or forward flexion of the neck. No preference was specified for left or right lateral decubitus positioning, allowing flexibility based on patient comfort and surgical requirements.
干预措施: Lateral positioning (Behavioral)
结局指标
主要结局
Incidence of hypoxaemia
时间窗: Within 24 hours after the surgery was completed
Defined as any occurrence of oxygen saturation (SpO2) ≤90% for at least five seconds during the initial 10 minute period after positioning.
