Ear zap might slash opioid need after big surgery
NCT ID NCT07260266
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a device that gently stimulates a nerve in the ear can help reduce the amount of strong painkillers (opioids) needed after major abdominal surgery. About 108 adults will receive either the real stimulation or a sham version while in the intensive care unit. Researchers will track opioid use, pain scores, and sleep quality for 24 hours after surgery.

Active substance
transcutaneous auricular vagus nerve stimulation (taVNS) device
What this could lead to
If it works, this could offer a non-drug way to manage pain after surgery, potentially reducing opioid use and side effects.
What could go wrong
This is a small, early-stage trial. The effect may be small or no better than a placebo, and results may not apply to all surgeries.
