A placebo-controlled, randomized trial of droperidol versus metoclopramide for outpatients undergoing gynecological laparoscopy under conscious sedation.
This study compared the prophylactic antiemetic efficacy and the adverse effects of 0.5 mg droperidol, 5.0 mg metoclopramide, and placebo for outpatients undergoing gynecological laparoscopy under conscious sedation. One hundred and fifty outpatients were randomly allocated, in a randomized double-blind manner, into three groups to receive intravenous normal saline, 0.5 mg droperidol, and 5.0 mg metoclopramide before operation. Conscious sedation using intravenous pethidine, midazolam and local infiltration were given to each patient during the operation. Emetic symptoms were graded twice by the patients, at discharge time and the 24th post-operative hour. The difference of antiemetic effect of both study drugs failed to reach statistical significance. There was also no statistical difference of intra-operative hypoxemia, sedation score, and discharge time among the groups. Therefore, using 0.5 mg droperidol or 5.0 mg metoclopramide is not effective in providing antiemetic prophylaxis for outpatients undergoing gynecological laparoscopy under conscious sedation.
