摘要
纤支镜引导下气管插管是处理紧急困难气道的核心手段。麻醉研究生在临床困难气道病例有限且紧急的情况下，操作机会极少是现行研究生培训中的突出问题。通过虚拟现实（virtual reality, VR）情境系统，搭建VR情境模拟平台，可使用VR平台搭载ORSIM模拟器进行分阶段系统性的培训实践，完善临床技能多元化考核体系。本研究推测，通过分组训练，使用VR平台搭载ORSIM模拟器的模拟器组在纤维支气管镜插管操作的水平上优于使用传统人体模型的传统组，缩短了气管插管的时间，并在处理困难气道方面表现出更高的综合能力。本研究旨在探讨在VR平台上使用ORSIM模拟器进行教学培训的最佳方案，并将具体的培训方法纳入麻醉专业研究生的培训体系，以弥补当前研究生培训体系的不足，从而提升研究生在应对紧急困难气道时的综合能力。

Abstract
Fibrilloscopy-guided tracheal intubation is a core tool for dealing with emergency difficult airway. Postgraduate anesthesia students have very few opportunities to operate in limited and urgent clinical difficult airway cases, which is a prominent problem in the current postgraduate training. Through the virtual reality (VR) situation system, a VR situation simulation platform can be built, and the VR platform can be used to carry out systematic training practice in stages with the ORSIM simulator, and to improve the diversified assessment system of clinical skills. In this study, it was hypothesized that through group training, the simulator group using the VR platform with the ORSIM simulator outperformed the conventional group using the traditional manikin in the level of fiberoptic bronchoscopy intubation maneuvers, shortened the time of tracheal intubation, and demonstrated higher overall competence in dealing with a difficult airway. The aim of this study was to investigate the best option for teaching and training using the ORSIM simulator on a VR platform and to incorporate specific training methods into the training system for postgraduate anesthesia students to compensate for the shortcomings of the current postgraduate training system so as to improve the overall competence of postgraduate students in dealing with an emergency difficult airway.
Key words： Virtual reality context system; ORSIM simulator; Postgraduate anesthesia students; Difficult airway
