Acupoint zaps may stop stomach acid during surgery
NCT ID NCT07338448
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether gentle electrical stimulation on acupoints can reduce stomach acid backing up into the throat during general anesthesia with an i-gel breathing tube. About 116 adults having surgery will be randomly assigned to receive the stimulation or no stimulation. The goal is to see if this simple, non-drug approach can lower the risk of acid reflux and related side effects like nausea after surgery.
