AbstractThis study compares the preoperative administration of ondansetron with that of droperidol or saline solution for the prevention of nausea and vomiting in otologic surgery patients. A total of 120 otherwise healthy individuals were randomly assigned to receive either saline solution, ondansetron (4 mg intravenously), or droperidol (25 microg/kg intravenously) before anesthetic induction. Intraoperative and postanesthesia care unit times were recorded along with incidence of nausea, vomiting, pain, nausea and recovery scores, and the administration of rescue antiemetics. Similar assessments were made during the next 24 hours. Demographics were similar, but more males received ondansetron. Anesthetic recovery scores were lower after administration of droperidol than after ondansetron. Incidence of nausea was similar between groups, but severity was greater with placebo and droperidol than with ondansetron. More vomiting occurred with placebo than with ondansetron or droperidol. No intergroup differences in rescue antiemetic administration were noted, however. Twenty-four hours later, more patients receiving placebo had nausea or vomited than patients receiving droperidol or ondansetron. Fewer women in the ondansetron group vomited than in the other two groups. Ondansetron 4 mg intravenously is as effective as droperidol and better than saline solution in preventing nausea and vomiting in patients undergoing otologic surgery. No cost advantage as determined by lower use of rescue antiemetics or shorter postanesthesia care unit times was noted after ondansetron therapy.
