Abstract
The antiemetic effects of droperidol, diphenidol, and placebo were compared in 210 patients subjected to minor gynecologic or urologic procedures. Atropine (0.6 mg), meperidine (1 mg/ kg) body mass, and either droperidol (5 mg), diphenidol (40 mg), or 2 ml of 0.9% saline were administered IM, 1 hour before general anesthesia. Trial drugs were presented in coded ampules so that the study was conducted double-blind. Droperidol appeared superior to both diphenidol (p<0.01) and placebo (p<0.001) in the prevention of vomiting, and reduced the incidence of nausea when compared to saline (p<0.05). Forty-four patients experienced side effects, which occurred with similar frequency in the 3 groups studied.
