METHODS: This randomized controlled study enrolled first-year residents who completed a 2-month rotation at an anaesthesiology department. Each rotation group was randomly assigned to the Macintosh laryngoscope (ML) or McGRATH™ MAC video laryngoscope (MML) group. Endotracheal intubation skills were evaluated on a mannequin after the rotation and at 3 and 6 months later. The primary endpoint was the time required for intubation. The secondary endpoint was the percentage of glottic opening (POGO) score.
RESULTS: Forty-six residents participated in this study and were assigned to the ML group (n = 23) or the MML group (n = 23). There were no significant differences between the sex, age and the number of endotracheal intubation procedures performed between the two groups. The time required for intubation was significantly shorter in the MML group compared with the ML group. The POGO scores did not show any significant differences between the two groups.
CONCLUSIONS: Compared with endotracheal intubation training using the Macintosh laryngoscope, the McGRATH™ MAC video laryngoscope shortened the intubation procedure and its effect remained even after 6 months.

方法:这项随机对照研究招募了在麻醉科完成为期2个月轮换的第一年住院医师。每个旋转组被随机分配到Macintosh喉镜(ML)或McGRATH™MAC视频喉镜(MML)组。旋转后以及3和6个月后,在人体模型上评估了气管内插管技巧。主要终点是插管所需的时间。次要终点是声门开放(POGO)评分的百分比。
结果:46名居民参与了这项研究,并被分配到ML组(n=23)或MML组(n=23)。性别之间没有显着差异,两组的年龄和气管插管次数。与ML组相比,MML组插管所需的时间明显缩短。POGO评分在两组之间没有显示任何显著差异。
结论:与使用Macintosh喉镜进行气管插管训练相比,McGRATH™MAC视频喉镜缩短了插管程序,其效果甚至在6个月后仍然存在.
