Abstract: | Dexamethasone alone and in combination with selective 5-hydroxytryptaminereceptor antagonists is of benefit in the prophylaxis of post-operativenausea and vomiting. In this study, the effectiveness of sucha combination in comparison to either drug alone is investigatedin day case gynaecological surgery. A total of 177 patientswere randomized to three treatment groups: dexamethasone 8 mg,ondansetron 4 mg, and dexamethasone 8 mg plus ondansetron 4mg. The only significant difference between groups was seenin the first 3 h when failure of prophylaxis was more frequentin patients who had received dexamethasone alone (P=0.0085;Fishers exact probability test). Confidence intervalanalysis indicates a modest treatment effect for the combinationand the decision whether to perform a larger study depends uponwhether such an effect is clinically relevant.
