. The competency of using video laryngoscopes (VL) for double-lumen tube (DLT) endobronchial intubations can be improved with constant training as assessed by measuring the learning curves. We hypothesized that the time to DLT intubation would be reduced over the intubation attempts. . A crossover manikin study. . University-affiliated hospital. . Forty-two novice medical students unfamiliar with DLT intubation. Participants were randomly allocated to two sequences, including DLT intubation, using King Vision and McGrath VLs. Each participant completed 100 DLT intubation attempts on both simulated easy and difficult airways on two different mannikins using the study devices (25 attempts for each). . The primary outcome was the time to DLT intubation. The secondary outcomes included the best glottic view, optimizing maneuvers, and intubation first-pass success. The use of King Vision VL was associated with a significantly shorter time to DLT intubation ( < 0.044 and < 0.05, respectively) and a higher percentage of glottic opening (POGO) compared to the McGrath VL ( < 0.011 and < 0.002, respectively) in the simulated "easy" and "difficult" over most of the intubation attempts. In the simulated "easy" airway, the first-pass success ratio was higher when using the King Vision VL (median [Minimum-Maximum] 100% [100%-100%] and 100% [88%-100%], = 0.012). . Novice medical students developed skills over intubation attempts, meaning achievement of a faster DLT intubation, better laryngeal exposure, and higher success rate on simulated "easy" and "difficult" airways. A median of 9 DLT intubations was required to achieve a 92% or greater DLT intubation success rate.
. 使用视频喉镜（VL）进行双腔管（DLT）支气管内插管的能力可以通过测量学习曲线来评估，通过不断的训练来提高。我们假设，随着插管尝试次数的增加，DLT 插管时间会减少。. 一项交叉模拟人研究。. 大学附属医院。. 42 名不熟悉 DLT 插管的新手医学生。 参与者被随机分配到两个序列，包括使用 King Vision 和 McGrath VL 进行 DLT 插管。每个参与者在两个不同的模拟人上完成 100 次 DLT 插管尝试，使用研究设备（每个模拟人 25 次尝试），包括模拟简单和困难气道。. 主要结局是 DLT 插管时间。次要结局包括最佳声门视图、优化操作和插管首次通过成功率。与 McGrath VL 相比，King Vision VL 与 DLT 插管时间明显缩短（分别<0.044 和<0.05）和更高的声门开放百分比（POGO）相关（分别<0.011 和<0.002）在模拟“简单”和“困难”气道中。在模拟“简单”气道中，使用 King Vision VL 的首次通过成功率更高（中位数[最小-最大]100%[100%-100%]和 100%[88%-100%]，=0.012）。. 新手医学生在插管尝试中发展了技能，这意味着更快地完成 DLT 插管、更好的喉部暴露和更高的模拟“简单”和“困难”气道的成功率。需要进行中位数为 9 次 DLT 插管才能达到 92%或更高的 DLT 插管成功率。
