【摘要】 目的 评价α2受体激动剂是否可以降低七氟烷引起的小儿术后躁动的发生率。 方法 通过检索Medline、荷兰医学文摘、Cochrane临床试验数据库、中国生物医学文献数据库和中国期刊网全文数据库等数据库,收集可乐定或右美托咪啶对七氟烷引起的小儿术后躁动的预防作用的随机对照试验(randomized controlled trial,RCT),提取资料和评估方法学质量,采用Cochrane协作网RevMan 5.0软件进行Meta分析。 结果 最终纳入11个RCT,其中104例患儿预防性使用右美托咪啶,268例患儿使用可乐定,365例患儿使用安慰剂。Meta分析显示,可乐定组小儿术后躁动发生率的比值比(OR)为0.31,95%CI为(0.15,0.61)(P=0.000 8);右美托咪啶组小儿术后躁动发生率的OR为0.16,95%CI为(0.08,0.31)(P lt;0.000 01)。 结论 α2受体激动剂可以显著降低七氟烷引起的小儿术后躁动的发生率。
【Abstract】 Objective To determine whether alpha2-adrenoceptor agonists can decrease emergence agitation (EA) in pediatric patients after sevoflurane anesthesia. Methods The Medline, Embase, Cochrane Library, CBM and CNKI were searched. All randomized controlled trials comparing clonidine or dexmedetomidine with other interventions in preventing emergence agitation after sevoflurane anesthesia were retrieved. Study selection and assessment, data collection and analyses were undertaken. Meta-analysis was done using the Cochrane Collaboration RevMan 5.0 software. Results Eleven articles reached our inclusion criteria and were included in the Meta-analysis. A total of 104 children treated with dexmedetomidine, 268 children treated with clonidine, and 365 children treated with placebo were evaluated for the incidence of emergence agitation. The pooled odds ratio for the clonidine subgroup was 0.31, with a 95% confidence interval of 0.15-0.61 (P=0.000 8). The pooled odds ratio for the dexmedetomidine subgroup was 0.16, with a 95% confidence interval of 0.08-0.31 (P lt;0.000 01). Conclusion Alpha2-adrenoceptor agonists can significantly decrease the incidence of emergence agitation in pediatric patients after sevoflurane anesthesia.
