增强现实在推进医学培训技术中的作用：一项关于环甲膜切除术的初步随机对照试验研究
The Role of Augmented Reality in Advancing Medical Training Techniques: A Pilot RCT Study on Cricothyroidotomy.
摘要(中文译文)
环甲膜切开术是处理困难气道的关键操作，然而其临床实施频率较低，导致医务人员的熟悉程度有限。本研究探讨使用HoloLens进行基于增强现实（AR）的培训与传统非头戴式显示设备（HMD）培训在环甲膜切开术教学中的效果。本研究旨在确认使用AR进行技术练习对参与者的操作能力、操作信心、学习自我效能感及实践满意度的作用，并为AR在医学教育中的应用提供基础数据。所有参与者首先通过笔记本电脑上的PowerPoint（PPT）接受初步指导。AR组通过HoloLens使用三维模型进行操作，而非HMD组则使用初始的PPT指导。通过前后测设计评估效果，包括环甲膜切开术预估时间、技能信心、NASA任务负荷指数、系统可用性量表及参与者满意度。AR组前测平均操作时间为188秒，非HMD组为150秒。在后测中，AR组记录为146秒，非HMD组为136秒，操作时间无统计学显著差异（>0.05）。HMD组信心水平显著提高（中位数从1.0升至5.0），且两组随时间推移在环甲膜切开术操作中表现出相似的熟练程度。满意度相似，但AR组报告的心理需求较低。尽管存在初始技术挑战，AR在不妨碍操作表现的情况下显示出增强学习和信心的潜力，表明需要进一步研究以优化AR在医学培训中的应用。
Abstract
Cricothyroidotomy is a critical procedure for managing difficult airways, yet it is infrequently performed, leading to limited familiarity among medical professionals. This study explores the effectiveness of augmented reality (AR)-based training using HoloLens compared to traditional non-head mounted device (HMD) training in teaching cricothyroidotomy. This study aims to confirm the effect of technical practice using AR on participants' performance ability, performance confidence, learning self-efficacy, and practical satisfaction, and to present basic data for using AR in medical education. All participants received initial guidance via PowerPoint (PPT) on laptops. The AR group performed the procedure with three-dimensional models via HoloLens, while the non-HMD group used the initial PPT guidance. Effectiveness was assessed through a pre- and post-test design, including cricothyroidotomy estimated time, skill confidence, NASA-Task Load Index, System Usability Scale, and participant satisfaction. The average pre-test procedure time for the AR group was 188 seconds, and 150 seconds for the non-HMD group. In the post-test, the AR group recorded 146 seconds and the non-HMD group 136 seconds, showing no statistically significant difference in procedure time (>0.05). The HMD group showed a significant improvement in confidence levels (median increase from 1.0 to 5.0), and both groups demonstrated similar proficiency in cricothyroidotomy performance over time. Satisfaction rates were similar, but the AR group reported lower mental demand. Despite initial technical challenges, AR showed potential for enhancing learning and confidence without compromising performance, indicating the need for further research to optimize AR in medical training.
