Direct laryngoscopy (DL) is widely recognized as the most commonly used method for tracheal intubation. However, growing evidence highlights the increasingly prominent role of video laryngoscopy (VL) in the management of difficult airways. This study aimed to determine the most effective medical education method to equip medical students with this critical skill. In addition to evaluating the contributions of an intubation training program utilizing direct laryngoscopy and video laryngoscopy to tracheal intubation success among inexperienced medical students, we also aimed to explore the potential benefits of combining these two techniques.
This mannequin-based study included 130 medical students. Before the study began, participants attended a 30-minute theoretical training session. Participants were randomly assigned to start with one of two scenarios. In each scenario, participants were given three attempts to perform intubation using each laryngoscope. The maximum allowable time for each intubation was set at 3 min. Students who successfully intubated within 3 min were recorded as successful, while those who failed to do so were recorded as unsuccessful.
The study demonstrated that VL provided higher success rates and shorter intubation times, particularly during the first and second attempts. However, it is noteworthy that no significant difference in success rates was observed between VL and DL during the third attempt.
This study highlights the necessity of integrating both VL and DL methods in intubation training programs. The combination of both approaches allows students to achieve quick initial results while progressively developing proficiency for more complex scenarios over time.

直接喉镜检查（DL）被广泛认为是气管插管最常用的方法。然而，越来越多的证据表明视频喉镜检查（VL）在困难气道管理中的作用日益突出。本研究旨在确定最有效的医学教育方法，使医学生掌握这项关键技能。除了评估利用直接喉镜检查和视频喉镜检查的插管培训计划对无经验医学生气管插管成功率的贡献外，我们还旨在探索将这两种技术相结合的潜在益处。
这项基于人体模型的研究纳入了130名医学生。在研究开始前，参与者参加了30分钟的理论培训课程。参与者被随机分配从两种场景之一开始。在每种场景中，参与者使用每种喉镜进行三次插管尝试。每次插管的最长允许时间设定为3分钟。在3分钟内成功插管的学生记录为成功，未成功的记录为失败。
研究表明，视频喉镜检查的成功率更高，插管时间更短，尤其是在第一次和第二次尝试时。然而，值得注意的是，在第三次尝试时，视频喉镜检查和直接喉镜检查的成功率没有显著差异。
本研究强调了在插管培训计划中整合视频喉镜检查和直接喉镜检查方法的必要性。两种方法相结合使学生能够迅速取得初步成果，同时随着时间的推移逐步提高应对更复杂情况的熟练程度。
