【摘要】 目的 評價α2受體激動劑是否可以降低七氟烷引起的小兒術后躁動的發生率。 方法 通過檢索Medline、荷蘭醫學文摘、Cochrane臨床試驗數據庫、中國生物醫學文獻數據庫和中國期刊網全文數據庫等數據庫,收集可樂定或右美托咪啶對七氟烷引起的小兒術后躁動的預防作用的隨機對照試驗(randomized controlled trial,RCT),提取資料和評估方法學質量,采用Cochrane協作網RevMan 5.0軟件進行Meta分析。 結果 最終納入11個RCT,其中104例患兒預防性使用右美托咪啶,268例患兒使用可樂定,365例患兒使用安慰劑。Meta分析顯示,可樂定組小兒術后躁動發生率的比值比(OR)為0.31,95%CI為(0.15,0.61)(P=0.000 8);右美托咪啶組小兒術后躁動發生率的OR為0.16,95%CI為(0.08,0.31)(P lt;0.000 01)。 結論 α2受體激動劑可以顯著降低七氟烷引起的小兒術后躁動的發生率。
【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.
