NCT ID NCT07506226
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether gargling cold water can ease dry mouth and thirst in patients who had major abdominal surgery. 88 adults took part, with half gargling cold water and the other half receiving standard care. The researchers measured thirst, dry mouth, discomfort, and satisfaction at several points after surgery. The goal was to find a simple, low-cost way to improve patient comfort after surgery.
