Ear nerve stimulation for less pain medication after major abdominal surgery
Part of Brain & nervous system clinical trials.
This trial tests whether a gentle electrical stimulation on the outer ear can help reduce the amount of strong pain medicine (opioids) you need after a major abdominal surgery. The stimulation targets a nerve called the vagus nerve, which helps control pain and recovery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 85 years old.
- You are scheduled for a major abdominal surgery under general anesthesia and will stay in the intensive care unit afterward.
- You do not have a history of fainting spells or other vagus nerve problems.
- You do not have a pacemaker or serious heart rhythm issues.
- You have not been taking strong pain medicines (opioids) or sedatives regularly before the surgery.

This study tests whether mild electrical stimulation applied to your ear can reduce pain and the need for pain medication after abdominal or urologic surgery. Researchers will try different stimulation frequencies to find what works best.
This trial tests if stimulating a nerve in your ear (vagus nerve) before and after noncardiac surgery can improve your recovery. It's for adults aged 18 to 84 having planned or time-sensitive surgery lasting at least 2 hours.
This study tests whether gentle electrical stimulation of a nerve in the ear (called taVNS) can help reduce anxiety before and after major abdominal surgery. It may offer a non-drug option for patients who feel nervous about their operation.
This trial tests if a non-invasive device that stimulates a nerve in your ear can help reduce pain after complex spine surgery. It may offer a drug-free option for managing postoperative pain.
This trial tests if using mild electrical pulses on the ear and head can help reduce pain after surgery. It may help patients need fewer painkillers after their operation.
This trial tests whether a gentle electrical stimulation delivered through the ear can reduce inflammation and pain after major spinal fusion surgery. If you are having a long spinal fusion, you might be able to join.
