ObjectiveTo investigate the method for preventing the postoperative nausea and vomiting (PONV) after laparoscopic gynecologic surgery.MethodsOne hundred and twenty patients being for laparoscopic gynecologic surgery at I- II grade as American Society of anesthesiologists (ASA) were randomly divided into three groups, 40 cases in each group. Twenty minutes before the operation, the mixture of 2. 5 mg Droperidol (1 mL) and 1 mL 0. 9% sodium chloride solution was injected into the bilateral Neiguan (PC 6) in group I , and an intravenous injection with 1 mL Droperidol was used in group II , while there was no treatment carried out in group Ill'. Twenty four hours after the operation, the frequency and degree of nausea and vomiting were observed and scored according to the criteria standard.ResultsThe incidence rate of nausea was 10. 0% (4/40) in group I , 57. 5% (23/40) in group II , which was significantly different from 80. 0% (32/40) in group III (P<0. 01, P<0. 05, respectively), while it was lower in group I than in group II (P<0. 01). The incidence rate of vomiting was 7. 5% (3/40) in group I , 52. 5% (21/40) in group II , which was significantly different from 75.0% (30/40) in group III (P<0.01, P<0.05 respectively), while it was lower in group I than in group II (P<0.01). No complication, such as obvious drowsiness, anxiety and extracorticospinal tract reaction, was observed among the three groups.ConclusionAcupoint injection at Neiguan (PC 6) with a small dose of Droperidol can effectively prevent the PONV after laparoscopic gynecologic surgery without other adverse effects.
