Abstract

BACKGROUND

Video laryngoscopes have been introduced in recent years as an alternative choice to facilitate tracheal intubation. We conducted a meta-analysis to assess their value when compared with direct laryngoscopy.

METHODS

PubMed and EMBASE were searched up until 24 September 2010. Randomised trials that reported data on the comparison of video laryngoscopes with direct laryngoscopy for tracheal intubation were included.

RESULTS

Eleven trials with a total of 1196 participants were identified. During tracheal intubation, video laryngoscopes can achieve a better view of the glottis and have a similar success rate [rate ratio 1.0; 95% confidence interval (CI) 0.99-1.01]. Overall, the time to tracheal intubation was not different between the video laryngoscopes and direct laryngoscopy (standardised mean difference 0.19; 95% CI -0.37-0.75). However, in a subgroup analysis, video laryngoscopes shortened the time taken for difficult intubation (standardised mean difference, -0.75; 95% CI -1.24 to -0.25).

CONCLUSION

Video laryngoscopes are a good alternative to direct laryngoscopy during tracheal intubation. The advantage seems to be more prominent when difficult intubation is encountered.

摘要

背景

近年来，视频喉镜已作为一种替代方法被引入，以方便气管插管。我们进行了一项荟萃分析，以评估其与直接喉镜相比的价值。

方法

检索 PubMed 和 EMBASE 截至 2010 年 9 月 24 日的数据。纳入比较视频喉镜与直接喉镜用于气管插管的随机试验，并报告了比较数据。

结果

确定了 11 项共 1196 名参与者的试验。在气管插管期间，视频喉镜可以获得更好的声门视野，且成功率相似[比值比 1.0；95%置信区间（CI）0.99-1.01]。总体而言，视频喉镜与直接喉镜的气管插管时间无差异（标准化均数差 0.19；95%CI -0.37-0.75）。但是，在亚组分析中，视频喉镜缩短了困难插管的时间（标准化均数差，-0.75；95%CI -1.24 至 -0.25）。
