套囊充气法对经鼻盲探气管插管有效性的meta分析

目的：探讨应用套囊充气法辅助经鼻盲探气管插管（BNTI）的有效性。方法：在中文期刊全文库（CHNK）、PUBMED2个电子文献数据库中,检索出有关套囊充气法对经鼻盲探气管插管术成功率影响的前瞻性对照研究的文献进行Meta分析。结果：10篇研究文献被选中。其中,对提供一次插管成功数据的8篇文献应用固定效应模型计算出套囊充气组BNTI一次成功率大于非套囊充气组,2组间合并统计P值〈0.05;对提供最终插管结果数据的9篇文献应用随机效应模型计算出囊充气组BNTI总成功率大于非套囊充气组,2组间合并统计P值〈0.01。结论：应用套囊充气法可提高经BNTI成功率,推荐可常规作为该技术的辅助方法。

Meta analysis for the effect of cuff inflation on the efficiency of blind nasotracheal intubation

Objective：To study whether cuff inflation can improve efficiency of blind nasotracheal intubation（BNTI）.Method：To collect the articles from CHNK and PUBMED electronic documental data base on case-control studies about the effect of cuff inflation on the success rates of BNTI for meta analysis.Result：Ten articles were selected.The fix effect model of metaMeta analysis was used in eight papers that provided the data of first attempts.Test for overall effect indicated that the cuff-inflation group had higher success rate in first intubation than the non-cuff inflation group（P0.05）;Nine papers that gave the results of final success of intubations were analyzed by the random effect model,and the test for overall effect demonstrated that the cuff-inflation group had higher total success rate of intubation than the non-cuff inflation group（P0.01）.Conclusion：Cuff inflation is an effective method for facilitating the success of BNTI.
