Postoperative nausea and vomiting (PONV) are common complications after general anesthesia. This study compared the effects of palonosetron and ondansetron in preventing PONV in patients undergoing thyroidectomy.
100 non-smoking female subjects were randomly assigned to a palonosetron group (n = 50) or an ondansetron group (n = 50). The patients of each group received 0.075 mg of palonosetron or 8 mg of ondansetron through intravenous bolus injection before induction of general anesthesia. The incidence of nausea and vomiting were monitored at 2 h, 24 h and 48 h after operation.
The incidence of PONV during 48 h after operation had no significant differences between the groups. However, the incidence of nausea was lower in the palonosetron group than in the ondansetron group (34% vs. 56%, P = 0.027). No differences were observed in incidences of vomiting, use of antiemetics and adverse events between the groups.
Palonosetron was more effective than ondansetron in preventing nausea for patients undergoing thyroidectomy. However, the effect of palonosetron or ondansetron in preventing PONV was similar.
