Effects of Lateral Decubitus Head-up Position, Supine Head-up Position, and Standard Lateral Decubitus Position on Hypoxemia During Recovery in Patients Undergoing Painless Gastroscopy and Colonoscopy: A Multicenter, Three-arm Randomized Controlled Trial
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
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.
Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:
• 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).

Treatments
Experimental: lateral decubitus head-up position group (LH group)
The patient maintains the predetermined lateral position with the head of the bed elevated at 30 degrees.
Experimental: supine head-up position group (SH group)
The patient was transferred from a pre-existing lateral decubitus position to a supine position without a headrest, with the head of the bed elevated at 30 degrees.
Experimental: standard lateral decubitus position group (SL group)
Patients should maintain their original left lateral position with the head of the bed elevated at 0 degrees.
