    Abstract:
    OBJECTIVE: to assess the effectiveness of ondansetron in preventing postoperative nausea and vomiting after elective laparoscopic cholecystectomy, and the effect of this anesthetic on hospital stay. METHODS: this randomized, double-blind, placebo-controlled study was done in the General Surgery Service of the Getafe University Hospital. Patients who were scheduled for laparoscopic cholecystectomy to treat uncomplicated cholelithiasis, and who had an ASA status of I-II, were recruited. Before surgery the patients received either ondansetron 4 mg or placebo intravenously. This study was approved by the local ethics committee. RESULTS: 56 patients were included, 29 in the ondansetron group and 27 in the placebo group. In the latter, 4 patients were later excluded because of conversion to open surgery. Postoperative nausea and emetic episodes were experienced by 7% of the patients in the ondansetron group and 47% in the placebo group (p = 0.0007). Oral intake started 7 h after surgery in the ondansetron group and 11 h after surgery in the placebo group (p = 0.04), with a mean difference of 4 h. Hospital stay was 30 h and 48 h respectively (p = 0.01), with a mean difference of 18 h. CONCLUSION: ondansetron given prior to surgery at a dose of 4 mg prevents postoperative nausea and vomiting after laparoscopic cholecystectomy, and reduces hospital stay.
