Comparison of prophylactic anti-emetic effects of ondansetron and dexamethasone in women undergoing day-case gynaecological laparoscopic surgery.
We aimed to determine the effect of ondansetron and dexamethasone on preventing post-operative nausea and vomiting (PONV). Sixty women undergoing laparoscopic gynaecological surgery were randomized to receive ondansetron 4 mg, dexamethasone 8 mg or saline. Drugs were administered 2 min before induction of anaesthesia, and anaesthesia and post-operative analgesic regimens were standardized. The incidence of PONV in the first 24 h after the operation was 35% in the ondansetron group, 55% in dexamethasone group and 85% in the control group. A significant difference between the groups was only seen in the first 3 h post-operatively. In this period, ondansetron was significantly more effective than dexamethasone and saline, but no differences were seen between dexamethasone and saline. In all treatment groups, post-operative visual analogue scale scores, sedation scores and usage of analgesics were similar. In conclusion, ondansetron, but not dexamethasone, prevented PONV in the first 3 h after gynaecological laparoscopic surgery.
