A randomized, double-blind study to evaluate the efficacy of ramosetron and palonosetron for prevention of postoperative nausea and vomiting after gynecological laparoscopic surgery.

ABSTRACT: Postoperative nausea and vomiting (PONV) is a common complication after anesthesia and surgery; 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists have been considered as a first-line therapy. Ramosetron and palonosetron are more recently developed drugs and have greater receptor affinity and a longer elimination half-life compared with older 5-HT3 receptor antagonists. The purpose of this study was to determine which drug is more effective for preventing PONV between ramosetron and palonosetron.We enrolled 100 patients undergoing gynecological laparoscopic surgery into this study. The subjects were divided into ramosetron group and palonosetron group. The medications were provided immediately before the induction of anesthesia. The occurrence of nausea and vomiting, severity of nausea according to a visual analogue scale, and rescue anti-emetic drug use were monitored immediately after the end of surgery and at 0-6 h, 6-24 h, and 24-48 h post-surgery.The incidence of vomiting was significantly lower in the palonosetron group than in the ramosetron group during 0-6 h (6% vs 26%, P = 0.012) and 0-48 h (14% vs 34%, P = 0.034). The incidence of nausea and overall PONV, and the use of rescue antiemetic were not significantly different during all time intervals. The severity of nausea was not different between the two groups.In conclusion, the incidence of PONV between the ramosetron and the palonosetron group have not shown the difference during 0-48 h, although palonosetron results in a lower incidence of vomiting during 0-6 h post-surgery.

Project description:Postoperative nausea and vomiting (PONV) is one of the most common adverse outcomes after strabismus surgery. The primary outcome of this prospective, randomized, double-blind study was to compare the incidences of nausea or vomiting, and patient satisfaction of ondansetron and ramosetron after strabismus surgery under general anesthesia. The secondary outcome was to investigate whether the number of involved extraocular muscles (EOMs) in strabismus surgery was related to PONV.One hundred and five patients (aged 18-60 years) undergoing strabismus surgery were allocated randomly to one of the three groups: placebo, ondansetron, or ramosetron. Patients received 2 ml placebo, 4 mg ondansetron, or 0.3 mg ramosetron at the end of surgery. Each of the three groups was subdivided into two subgroups according to the number of EOMs involved in the surgery: subgroup S, single-muscle correction; subgroup M, multiple-muscle correction. The incidences of nausea or vomiting, and patient satisfaction at 2, 24 and 48 h after surgery were analyzed as primary outcome. With regard to subgroups S and M in the placebo, ondansetron and ramosetron groups, incidences of nausea or vomiting, and patient satisfaction at 2, 24 and 48 h after surgery were analyzed as seconadary outcome.The incidence of nausea was significantly lower in the ramosetron group at 2 h (9.4 %) than in the placebo (45.2 %) and ondansetron (34.7 %) groups (P < 0.05). The incidence of nausea was also significantly lower in the ramosetron group at 24 h than in the other groups (P < 0.05). Patients in the ramosetron group were more satisfied at 2 h (8.11 ± 0.98) and 24 h (8.50 ± 0.67) after surgery than those in the other groups (P < 0.05). With regard to subgroups S and M in the placebo, ondansetron and ramosetron groups, there were no significant differences in either the incidence of nausea or patient satisfaction.Ramosetron has superior antiemetic activity to ondansetron in adult strabismus surgery patients. The number of EOMs involved in strabismus surgery was not related to the incidence of PONV.Clinical Research Information Service (CRiS) Identifier: KCT0000688 .
