Ear zaps may cut opioid need after surgery
NCT ID NCT07633444
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a safe, non-invasive nerve stimulation on the ear can lower pain and the need for strong painkillers after abdominal or urologic surgery. 174 adults will receive either real stimulation at different frequencies or a sham (fake) treatment before and after surgery. Researchers will measure pain, opioid use, nausea, and recovery quality to see if this approach works.
