Text: We found no differences in nausea or vomiting at 30 min and 2 h postoperatively ; we found no difference in the incidence of nausea between dexamethasone-haloperidol and dexamethasone-placebo groups at 6 h [relative risk (RR) 0. 82, 95 % confidence interval (CI) 0. 56-1. 25] and 24 h (RR 0. 79, 95 % CI 0. 56-1. 1), but the cumulative incidence of vomiting in the dexamethasone-haloperidol group was significantly lower at 6 h (RR 0. 57, 95 % CI 0. 39-1. 05) and 24 h (RR 0. 54, 95 % CI 0. 31-0. 86).
