Unanticipated difficulties during tracheal intubation and failure to intubate are among the leading causes of anaesthesia-related morbidity and mortality. Using the technique of video laryngoscopy, the alignment of the oral and pharyngeal axes to facilitate tracheal intubation is unnecessary. In this study we evaluated the McGrath Series 5 videolaryngoscope for tracheal intubation in 61 patients who exhibited Cormack and Lehane grade 3 or 4 laryngoscopies with a Macintosh laryngoscope. Using the McGrath resulted in an improved glottic view, compared to Macintosh laryngoscope. Laryngoscopy was improved by one grade in 10%, by two grades in 80% and by three grades in 10% of cases (p < 0.0001). The success rate for intubation was 95% with the McGrath. These results suggest that the McGrath videolaryngoscope can be used with a high success rate to facilitate tracheal intubation in difficult intubation situations.
在气管插管过程中出现意外困难和插管失败是导致麻醉相关发病率和死亡率的主要原因之一。使用视频喉镜技术，口腔和咽轴的对齐以促进气管插管是不必要的。在这项研究中，我们评估了 McGrath Series 5 视频喉镜在 61 例 Cormack 和 Lehane 分级 3 或 4 级的患者中的气管插管情况，这些患者使用 Macintosh 喉镜进行了检查。与 Macintosh 喉镜相比，使用 McGrath 喉镜可获得改善的声门视图。喉镜检查在 10%的病例中提高了一个等级，在 80%的病例中提高了两个等级，在 10%的病例中提高了三个等级（p < 0.0001）。使用 McGrath 进行插管的成功率为 95%。这些结果表明，McGrath 视频喉镜可用于高成功率的困难插管情况，以促进气管插管。
