INTRODUCTION: Midazolam hydrochloride is a widely accepted benzodiazepine for premedication in pediatric pa-tients. However, there is no consistent conclusion regarding which route of administration is best. We performed a meta -analysis to assess the efficacy and safety of oral versus intranasal midazolam premedication in children.EVIDENCE ACQUISITION: The PubMed, Embase, Cochrane Library, and Google Scholar databases were searched from inception to June 2022, for randomized controlled trials comparing oral versus intranasal midazolam. Primary out-comes included satisfactory mask acceptance for induction and satisfactory sedation at separation from parents. Second-ary outcomes included the incidence of postoperative nausea and vomiting, incidence of nasal irritation, postoperative recovery time, and hemodynamic changes.EVIDENCE SYNTHESIS: Data from 14 studies involving a total of 901 children were obtained. The results indicated that intranasal and oral midazolam premedication in children provided similar satisfactory mask acceptance for induction (RR, 1.02; 95% CI, 0.93-1.13; P=0.64; I2=0%), satisfactory sedation at separation from parents (RR, 0.99; 95% CI, 0.89-1.10; P=0.90; I2=57%), and postoperative recovery time (WMD,-8.01; 95% CI,-20.16-4.14; P=0.20; I2=85%). Addition-ally, intranasal midazolam premedication was associated with lower incidence of postoperative nausea and vomiting (RR, 0.70; 95% CI, 0.51-0.96; P=0.03; I2=0%) and shorter onset time.CONCLUSIONS: Differences between intranasal and oral midazolam in satisfactory mask acceptance for induction, sat-isfactory sedation at separation from parents, and postoperative recovery time were not significant. Intranasal midazolam premedication was associated with shorter onset time and higher incidence of nasal irritation.(Cite this article as: Chen S, Lang B, Wu L, Zhang W.
