Comparison of ondansetron with ondansetron plus dexamethasone in the prevention of postoperative nausea and vomiting.

The purpose of this double-blind, randomized study was to compare the effectiveness of ondansetron plus saline versus ondansetron plus dexamethasone in the prevention of postoperative nausea and vomiting. Of 180 women having general anesthesia for major gynecologic surgery, 89 received intravenous ondansetron, 4 mg, plus saline (Group 1) and 91 received intravenous ondansetron, 4 mg, plus dexamethasone 8 mg (Group 2) during their operation. A complete response, defined as no emesis and no need for rescue antiemetic during the 24-h postoperative period, occurred in 38% of patients in Group 1 and in 52% in Group 2 (P = 0.
