Review Meta AnalysisDexmedetomidine for preventing sevoflurane-related emergence agitation in children: a meta-analysis of randomized controlled trials.
Emergence agitation (EA) is a common problem after sevoflurane anesthesia in children. Prophylactic dexmedetomidine has been directed at this issue; however, the efficacy remains controversial. We therefore conducted a meta-analysis of randomized controlled trials (RCTs) to evaluate the effectiveness of dexmedetomidine on the incidence of sevoflurane-related EA. ⋯ Dexmedetomidine reduced the incidence of sevofurane-related EA (pooled RR = 0.351; 95% CI: 0.275-0.449; P = 0.965; heterogeneity test, I(2) = 0.0%), and it also resulted in a lower incidence of severe EA (pooled RR = 0.119; 95% CI: 0.033-0.422; P = 0.962; heterogeneity test, I(2) = 0.0%). All subgroup analyses for potential sources of heterogeneity showed a lower incidence of sevoflurane-related EA after dexmedetomidine administration. This meta-analysis demonstrated that dexemedetomidine was effective in reducing the incidence of sevoflurane-induced EA in children as compared with placebo.
