In plain words

What the trial is, and whether it could suit you

Through a multicenter, three-arm randomized controlled trial design, this study aimed to compare the effects of three positioning strategies-side-lying with elevated head position, supine with elevated head position, and standard side-lying position-on the incidence of hypoxemia during the recovery phase in patients undergoing painless gastroscopy and colonoscopy. The goal was to provide clinicians with a simple, non-invasive, and cost-effective optimization strategy.

Scheduled for combined painless esophagogastroduodenoscopy/colonoscopy or either of the two procedures. 5. Ability to understand the study protocol and provide written informed consent. 6. A broad set of inclusion criteria was adopted to enroll a patient population that better reflects routine clinical practice. The study aimed to enhance the generalizability of the findings by including patients with various comorbidities, such as preprocedural hypoxemia (room-air SpO₂ ≤ 90%), history of pulmonary surgery, obstructive sleep apnea (OSA), and other pulmonary conditions (including asthma, COPD, chronic bronchitis, emphysema, and pulmonary bullae). Exclusion Criteria: 1. Severe cardiovascular or cerebrovascular diseases. 2. Pregnant patients. 3. History of hypersensitivity to ciprofol. Withdrawal Criteria: 1. Endotracheal intubation required during the procedure. 2. Voluntary withdrawal requested by the patient or their legal representative.
