Microvascular decompression (MVD) is associated with a particularly high risk of postoperative nausea and vomiting (PONV) among craniotomy patients. However, there is no information regarding the effect of prophylactic palonosetron and sugammadex on PONV in patients undergoing MVD under propofol-maintained anesthesia.Medical records of 274 adults who had undergone MVD under propofol-maintained anesthesia were reviewed. Patients were classified into 4 groups, based on the reversal agent used (sugammadex/pyridostigmine) and whether or not prophylactic palonosetron was used. The PONV incidence and risk factors were analyzed according to the use of these agents.The overall incidence of PONV was 30.7% during the first 24 hours postoperatively. The incidence of PONV was lower in the group using combination of prophylactic palonosetron and sugammadex (19.3%) compared with the group not using both agents (37.2%). The combined use of the prophylactic palonosetron and sugammadex was identified as a factor affecting the occurrence of PONV in both univariable (OR = 0.40, 95% CI: 0.21-0.77, P = .006) and multivariable (OR = 0.38, 95% CI: 0.20-0.75, P = .005) logistic regression analyses. In multivariable logistic regression analysis, female sex was also significant independent risk factor in PONV (OR = 2.62, 95% CI: 1.35-5.08, P = .004).In this retrospective observational study, the combined use of prophylactic palonosetron before anesthetic induction and sugammadex as a reversal of neuromuscular blockade are associated with a reduction in the incidence of PONV in patients undergoing MVD under propofol-maintained anesthesia.
