BACKGROUND
Increased evidence indicates that the Airtraq is useful for difficult tracheal intubations. The aim of this meta-analysis was to assess the efficacy of the Airtraq in difficult airways, comparing with that of Macintosh laryngoscopy.
METHODS
The systematic search, data extraction, critical appraisal, and pooled analysis were performed according to the PRISMA statement. The relative risk (RR), mean difference (MD), and their corresponding 95% confidence intervals (CIs) were calculated by the Comprehensive Meta-analysis version 2.2.040 software for dichotomous and continuous outcomes, respectively.
RESULTS
Sixteen randomized controlled trials included 863 tracheal intubations by Airtraq and 865 tracheal intubations by Macintosh laryngoscopy. Airtraq showed higher success rate (RR 1.242, 95%CI 1.137 to 1.357, P<0.00001) and shorter duration for instrumentation (MD-8.259 s, 95%CI-13.122 s to-3.396 s, P <0.00087).
CONCLUSIONS
There is considerable evidence that Airtraq has an advantage over Macintosh laryngoscope in difficult airways.
背景
越来越多的证据表明，Airtraq喉镜在困难气管插管中很有用。本荟萃分析的目的是评估Airtraq喉镜在困难气道中的有效性，并与麦金托什喉镜进行比较。
方法
根据系统评价和Meta分析的首选报告项目（PRISMA）声明进行系统检索、数据提取、批判性评价和汇总分析。分别使用Comprehensive Meta-analysis 2.2.040软件计算二分法和连续结果的相对风险（RR）、平均差（MD）及其相应的95%置信区间（CI）。
结果
16项随机对照试验纳入了863例使用Airtraq喉镜的气管插管和865例使用麦金托什喉镜的气管插管。Airtraq喉镜显示出更高的成功率（RR 1.242，95%CI 1.137至1.357，P<0.00001）和更短的操作时间（MD -8.259秒，95%CI -13.122秒至-3.396秒，P<0.00087）。
结论
有大量证据表明，在困难气道中，Airtraq喉镜比麦金托什喉镜更具优势。
