          Postoperative vomiting causes patients distress and delays discharge after outpatient surgery. Although P6 electroacupuncture is recognized as having an antiemetic effect, its inconvenient instrumentation may limit its clinical applicability. The purpose of this study was to explore a simple and effective alternative method for control of postoperative vomiting in outpatient surgery. We prospectively compared the effect of P6 acupoint injection with 0.2 ml 50% glucose in water (G/W) and intravenous injection of 20 micrograms/kg droperidol for prevention of vomiting in 120 consecutive outpatients undergoing gynecological laparoscopy with general anesthesia. Patients were randomly allocated to receive P6 acupoint injection, i.v. droperidol, or nothing as control group. Both P6 acupoint injection and i.v. droperidol 20 micrograms/kg were found to have a significant antiemetic effect when compared with the control group. We conclude that P6 acupoint injection with 50% G/W is a simple and effective method for reducing the incidence of postoperative emesis in outpatient surgery.
