Early and successful management of the airway in the prehospital and hospital settings is critical in life-threatening situations.
We aimed to perform endotracheal intubation (ETI) by direct laryngoscopy (DL) and video laryngoscopy (VL) on airway manikins on a moving track and to compare the properties of intubation attempts.
Overall, 79 participants with no previous VL experience were given 4 h of ETI training with DL and VL using a standard airway manikin. ETI skill was tested inside a moving ambulance. The number of attempts until successful ETI, ETI attempt times, time needed to see the vocal cords, and the degree of convenience of both ETI methods were recorded.
Overall, 22 of 79 individuals were men; mean age was 30.3 ± 4.5 years. No difference was found in the comparison of the two methods (p = 0.708). Time needed to see the vocal cords for those who were successful in their first attempt were between 1 and 8 s in both methods. In the VL method, time needed to see the vocal cords (p = 0.001) and the intubation time (p < 0.001) in the first attempt were shorter than in the DL method. The VL method was easier (p < 0.001). The success rate was 97.5% in DL and 93.7% in VL.
The VL method is rapid and easier to see the vocal cords and perform successful ETI. Therefore, it might be preferred in out-of-hospital ETI applications.
在危及生命的情况下，对院前和医院环境中的气道进行早期和成功的管理至关重要。
我们旨在通过直接喉镜（DL）和视频喉镜（VL）对移动轨道上的气道模型进行气管插管（ETI），并比较插管尝试的特性。
共有 79 名无 VL 经验的参与者接受了 4 小时的 ETI 训练，使用标准气道模型进行 DL 和 VL。ETI 技能在移动救护车内进行测试。记录成功 ETI 的尝试次数、ETI 尝试次数、看到声带所需的时间以及两种 ETI 方法的便利性程度。
共有 79 名参与者中有 22 名是男性；平均年龄为 30.3±4.5 岁。两种方法之间的比较没有差异（p=0.708）。在首次尝试成功的情况下，两种方法看到声带所需的时间均在 1 至 8 秒之间。在 VL 方法中，首次尝试看到声带所需的时间（p=0.001）和插管时间（p<0.001）均短于 DL 方法。VL 方法更简单（p<0.001）。DL 的成功率为 97.5%，VL 的成功率为 93.7%。
VL 方法快速且更容易看到声带并进行成功的 ETI。因此，它可能在院外 ETI 应用中更受欢迎。
