A randomized, double-blind trial evaluating the efficacy of palonosetron with total intravenous anesthesia using propofol and remifentanil for the prevention of postoperative nausea and vomiting after gynecologic surgery

Abstract

Purpose

Palonosetron has potent and long-acting antiemetic effects for postoperative nausea and vomiting (PONV). The aim of this study was to prospectively evaluate the efficacy of palonosetron when used with total intravenous anesthesia (TIVA) using propofol and remifentanil for the prevention of PONV in patients undergoing laparoscopic gynecologic surgery.

Methods

This prospective double-blind study comprised 100 female American Society of Anesthesiologist physical status I and II patients who were undergoing laparoscopic gynecologic surgery under TIVA. The patients were randomly assigned to two groups—the palonosetron plus TIVA group (palonosetron 0.075 mg i.v., n = 50) and the TIVA group (normal saline 1.5 ml i.v., n = 50). The treatments were given before the induction of anesthesia. The incidence of PONV, severity, number of rescue antiemetics, adverse effects, and patient satisfaction during the first 24 h after surgery were evaluated.

Results

The demographic profiles of the patients in the two groups were comparable. The overall incidence of PONV (0–24 h) was significantly lower in the TIVA plus palonosetron group than in the TIVA group (34 vs 58 %, p = 0.027). In particular, during the 6–24 h after surgery, the incidence of PONV (14 vs 30 %, p = 0.03) and the incidence of moderate to severe nausea (6 vs 22 %, p = 0.041) were significantly lower in the TIVA plus palonosetron group than in the TIVA group. There were no significant differences in adverse effects, use of rescue antiemetics or patient satisfaction.

Conclusion

Combining palonosetron with TIVA can be considered as a good method to prevent PONV, not only during the short postoperative period but also especially during the 6–24-h period after anesthesia.
