医学生使用直接喉镜与新型可视喉镜进行模拟人气管插管训练的交叉对照研究

UsingMacintosh and a novel optical laryngoscope for simulation endotracheal intubation: a crossover study

目的:气管插管是医学生必须掌握的复杂技术,拟探讨提高该技术学习效果的教学方法。方法:本交叉对照研究中,10名实习医生采用直接喉镜和Airtraq喉镜共进行100次模拟人气管插管。结果:使用Airtraq喉镜时,插管时间短[(22.1±14.9)s vs (39.6±42.2)s,P<0.05],成功率高(100%vs 88%)。结论:可考虑在传统喉镜教学基础上加入可视喉镜教学,具有提高学习积极性、加强教学效果和增强临床实践自信心的效果。

Objective: Tracheal intubation is a complex technique that medical students must master. It is proposed to explore teaching methods to improve the learning effect of this technology. METHODS: In this cross-over study, 10 interns performed a total of 100 simulated human endotracheal intubations using a direct laryngoscope and an Airtraq laryngoscope. RESULTS: When using the Airtraq laryngoscope, the intubation time was short(22.1±14.9 vs 39.6±42.2 s, P<0.05) with a high success rate(100% vs.88%). Conclusion: It can be considered to add visual laryngoscopy teaching based on traditional laryngoscopy teaching, which has the effect of improving learning enthusiasm, enhancing teaching effect and enhancing self-confidence in clinical practice.
