Randomized Controlled Trial Multicenter Study Clinical Trial
Ondansetron prevents postoperative emesis in male outpatients. S3A-379 Study Group.
To determine (1) the efficacy and safety of ondansetron in the prevention of postoperative nausea and vomiting (PONV) in male outpatients; (2) prognostic factors for PONV in male outpatients; and (3) patients' perceptions of the debilitating effects of PONV in the ambulatory surgery setting. ⋯ Ondansetron 4 mg was more effective than placebo in preventing PONV in male outpatients. Males at potential risk for developing PONV include: (1) those with a history of motion sickness and/or PONV; (2) patients undergoing nonorthopedic procedures; and (3) procedures lasting longer than one hour. Such patients may benefit from receipt of a prophylactic antiemetic. Postoperative nausea and vomiting has a debilitating effect that can be differentiated by patients from the effects of surgery itself.
