Effect of Lateral Versus Supine Positions on Postoperative Hypoxemia
China960 participantsStarted 2026-04-22
Plain-language summary
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.

Inclusion criteria
. Age ≥ 18 years.
. Both sexes.
. American Society of Anesthesiologists (ASA) physical status classification I-III.
. Scheduled for combined painless esophagogastroduodenoscopy/colonoscopy or either of the two procedures.
. Ability to understand the study protocol and provide written informed consent.
. 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).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is comparing lateral versus supine positions after surgery to see which one reduces low oxygen levels — is either position already considered safer based on what's known, or is there genuine uncertainty that makes this study necessary?
2Since this trial doesn't have a traditional phase like drug trials do, can you help me understand what the main risk is for me as a participant — is it primarily the discomfort or potential complications of being positioned one way versus the other during recovery?
3The study is measuring how often patients experience low oxygen levels in the recovery room — how would my own health history, like any lung or breathing conditions, affect whether one position might already be preferred for me personally?
4If I take part in this trial, would I have any control over which position I'm placed in, or would that be randomly decided, and how would the team monitor my oxygen levels and respond if they dropped?
5Would joining this trial change anything else about my standard postoperative care, or would everything except the recovery position remain exactly the same as it would be if I weren't in the study?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
