BackgroundThe purpose of this study was to evaluate the effect of palonosetron combined with dexamethasone for the prevention of PONV compared to dexamethasone alone in women who received intravenous patient-controlled analgesia (IV-PCA) using fentanyl.MethodsIn this randomized, double-blinded, placebo-controlled study, 204 healthy female patients who were scheduled to undergo elective surgery under general anesthesia followed by IV-PCA for postoperative pain control were enrolled. Patients were divided into two groups: the PD group (palonosetron 0.075 mg and dexamethasone 5 mg IV; n = 102) and the D group (dexamethasone 5 mg IV; n = 102). The treatments were given after the induction of anesthesia. The incidence of nausea, vomiting, severity of nausea, and the use of rescue anti-emetics during the first 48 hours after surgery were evaluated.ResultsThe incidence of PONV was significantly lower in the PD group compared with the D group during the 0-24 hours (43 vs. 59%) and 0-48 hours after surgery (45 vs. 63%) (P < 0.05). The severity of nausea during the 6-24 hours after surgery was significantly less in the PD group compared with the D group (P < 0.05). The incidence of rescue antiemetic used was significantly lower in the PD group than in the D group during the 0-6 hours after surgery (13.1 vs. 24.5%) (P < 0.05).ConclusionsPalonosetron combined with dexamethasone was more effective in preventing PONV compared to dexamethasone alone in women receiving IV-PCA using fentanyl.
