CONTEXT
The difficult airway is an important scenario in anaesthesia due to the impact of its potential complications, and the difficulty in predicting its presence in current clinical practice.
METHODS
Systematic review of articles in English and Spanish retrieved from MEDLINE (Ovid), LILACS and EMBASE up to March 2018. The search strategy was defined by the authors. The reviewers uploaded the studies to specially designed tables in order to qualitatively analyse the results of each paper.
RESULTS
A total of 3602 studies were identified. Thirty-four of these were included in the qualitative review. The most commonly used definition of difficulty was the Cormack-Lehane 3 or 4 classification, with a weighted mean incidence of 7.23%. The most relevant finding was the methodological weaknesses in obtaining these scales.
CONCLUSIONS
Available prediction models show limited discrimination, and weaknesses were detected in the methodology used to develop these prediction rules.
背景
由于潜在并发症的影响，困难气道是麻醉中的一个重要情况，而且在当前的临床实践中预测其存在具有一定难度。
方法
对截至 2018 年 3 月从 MEDLINE（Ovid）、LILACS 和 EMBASE 检索到的英文和西班牙文文章进行系统综述。作者定义了检索策略。评审员将研究上传到专门设计的表格中，以便对每篇论文的结果进行定性分析。
结果
共确定了 3602 项研究。其中 34 项研究被纳入定性综述。最常用的困难定义是 Cormack-Lehane 3 或 4 级分类，加权平均发生率为 7.23%。最相关的发现是获得这些量表的方法学上的弱点。
结论
现有的预测模型显示出有限的辨别力，并且在开发这些预测规则时发现了方法学上的弱点。
