Abstract
BACKGROUND: Previous randomized controlled trials regarding the effectiveness of perioperative midazolam in preventing postoperative nausea and vomiting (PONV) have produced conflicting results. Consequently, the present systematic review was performed to assess the effect of perioperative administration of midazolam on PONV. METHODS: The MEDLINE®, Embase, and Cochrane Central Register of Controlled Trials databases were searched to identify all randomized controlled trials that investigated the effectiveness of midazolam under general anesthesia. The primary end points were defined as postoperative nausea (PON), postoperative vomiting (POV), and PONV. RESULTS: From 16 studies, 1433 patients were included in the final analysis. Compared with the control group, patients who received midazolam showed a lower overall incidence of PON (risk ratio [RR], 0.51; 95% confidence interval [CI], 0.40-0.65; I = 35%; number needed to treat [NNT] = 6; number of included studies [n] = 11), POV (RR, 0.46; 95% CI, 0.33-0.65; I = 0%; NNT = 8; n = 10), and PONV (RR, 0.45; 95% CI, 0.36-0.57; I = 31%; NNT = 3; n = 7). CONCLUSIONS: Perioperative administration of midazolam was effective in preventing PON, POV, and PONV.
