About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients aged 18 or above and 80 or below who received general anesthesia and intubation
Disqualifiers
Presence of hypotension or bradycardia upon entering the anesthesia recovery room;
Preoperative hypoxemia;
Surgical procedures where body position adjustment is not possible or is prohibited due to the nature of the surgery;
Surgical procedures involving severe cardiovascular or cerebrovascular diseases, severe pulmonary diseases, intracranial hypertension, etc.;

Treatments tested in this trial
Lateral positioning
BehavioralPatients 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.
Semirecumbent positioning
BehavioralPatients in the semi-recumbent position were placed in the bed and the head of the bed was raised by 30 °, allowing flexibility based on patient comfort and surgical requirements.
Treatment groups
1,200 Participants
are divided into 2 treatment groupsGroup A: Semirecumbent positioningExperimental treatment 1 intervention
Group B: Lateral positioningExperimental treatment 1 intervention
