Randomized Controlled Trial Comparative Study Clinical Trial
Ondansetron and droperidol in the prevention of postoperative nausea and vomiting.
We have performed a prospective, randomized, double-blind clinical study to assess the efficacy of ondansetron, droperidol, or both, in preventing postoperative emesis. We studied 242 patients undergoing biliary or gynaecological surgery under general anaesthesia. ⋯ Groups 2 and 4 had greater sedation scores than group 1 during the first 3 h (P < 0.01). We conclude that both droperidol and ondansetron showed a significant antiemetic effect, ondansetron was not significantly better than droperidol, and the combination of droperidol and ondansetron was better than droperidol but no better than ondansetron alone.

Randomized Controlled Trial Clinical Trial
Dexamethasone reduces nausea and vomiting after laparoscopic cholecystectomy.
We have evaluated the antiemetic effect of i.v. dexamethasone compared with saline in the prevention of nausea and vomiting after laparoscopic cholecystectomy. We studied 90 patients requiring general anaesthesia for laparoscopic cholecystectomy, in a randomized, double-blind, placebo-controlled study. The dexamethasone group (n = 45) received dexamethasone 8 mg i.v. and the saline group received saline 2 ml i.v. at induction of anaesthesia. ⋯ We found that 10% of patients in the dexamethasone group compared with 34% in the saline group reported vomiting (P < 0.05). Of note, the total incidence of nausea and vomiting was 23% in the dexamethasone group and 63% in the saline group (P < 0.001). We conclude that dexamethasone 8 mg significantly decreased the incidence of nausea and vomiting after laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of low-dose epidural with combined spinal-epidural analgesia for labour.
We have performed a randomized comparison of two low-dose epidural regimens for analgesia in labour, differing only in the manner in which initial analgesia was established. In the epidural (EPI) group, 484 women received a loading dose of 20 ml of 0.1% bupivacaine with fentanyl 2 micrograms ml-1. In the combined spinal-epidural (CSE) group, 524 women received a spinal injection of plain bupivacaine 2.5 mg with fentanyl 25 micrograms. ⋯ Other comparisons between groups revealed no differences. These findings may have been affected by an uneven distribution of multiparous women between the groups (25% in the EPI group and 34.2% in the CSE group; P = 0.002). However, subgroup analysis of primiparous and multiparous women did not alter the results.
