Abstract
It is not fully known if there are significant differences in the incidence of post-operative nausea and vomiting（PONV）in patients undergoing laparoscopic surgery under general anesthesia following administration of desflurane compared to other conventional maintenance anesthetics, such as sevoflurane and propofol. This study was aimed to address this issue using network meta-analysis of relevant randomized controlled trials. Summary effect sizes were calculated as odds ratios（ORs）with 95％ confidence intervals（CIs）. The incidence of PONV after administration of different anesthetics was compared by surface under the cumulative ranking curve（SUCRA）analysis. The odds of desflurane vs sevoflurane, desflurane vs propofol, and sevoflurane vs propofol contributing to the incidence of PONV were 0.44（95％ CI, 0.12-1.61）, 2.43（95％ CI, 0.72-8.26）, and 5.50（95％ CI, 1.78-16.93）, respectively. The SUCRA scores for desflurane, sevoflurane, and propofol were 48.3, 5.6, and 96.1, respectively. The incidence of PONV after desflurane administration did not differ significantly from that after sevoflurane and propofol administration. However, the odds of PONV occurring after sevoflurane administration were significantly higher than those after propofol administration. Moreover, the SUCRA score after desflurane administration was greater than that after sevoflurane administration. These results confirm the safety of desflurane regarding PONV in patients undergoing laparoscopic surgery under general anesthesia.
