NCT ID NCT05454475
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 270 adults undergoing sedated ultrasound endoscopy to see if the temperature of water used during the procedure affects image quality, patient comfort, and safety. Participants were randomly assigned to receive cold, warm, or hot water. The goal is to find the optimal temperature that reduces gut movement and improves diagnosis while keeping patients comfortable.
