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.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

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.
