Acupuncture for Prevention of Postoperative Nausea and Vomiting After Laparoscopic Cholecystectomy

Overview

The purpose is to find out if intraoperative acupuncture performed by needling PC 6 and LI4 point bilaterally, and Yin Tang point will help reduce the incidence postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when added to a prophylactic regimen consisting of ondansetron and dexamethasone. The hypothesis is that the addition of this acupuncture treatment to ondansetron and dexamethasone given for prophylaxis will help reduce the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when compared to patients receiving ondansetron and dexamethasone without acupuncture.
