Summary

This study tested a wearable bracelet that delivers mild electrical stimulation to a point on the wrist (PC6) to prevent nausea and vomiting after laparoscopic surgery. 326 women participated, and the bracelet was used alongside standard anti-nausea drugs. The goal was to see if adding this device reduces nausea in the first 24 hours after surgery.
