简介 模拟在医学教育和程序技能培训中的价值已得到广泛认可。尽管如此，许多基于人体模型的培训师仍受到受训者无法查看内部解剖结构的限制。本研究评估了第一人称视角增强现实 (AR) 训练器在针插入方面的可用性和可行性，作为中心静脉导管放置的一部分。方法 四十名受试者，包括医学生、麻醉科住院医师和教师参与。提供增强现实眼镜，通过该眼镜投影相关的内部解剖标志。经过一段时间的练习后，参与者被要求在没有 AR 投影内部解剖结构的情况下将针放入人体模型中。记录了受训者正确放置针的能力。参与者还完成了一项简短的调查，描述他们对 AR 技术的看法。结果 参与者表示 AR 技术很真实（77.5%），并且查看内部解剖结构的能力很有帮助（92.5%）。此外，分别有85%和82.1%的人认为AR技术可以促进学习，应纳入医疗培训。有经验的参与者和无经验的参与者成功放置针的能力相似；然而，经验不足的参与者更有可能无意中刺穿颈动脉。结论 这项试点研究的结果证明了 AR 技术作为模拟医疗技能培训的潜在重要辅助手段的可用性和可行性。下一步重要的一步是在各种模拟医疗培训环境下进一步开发和评估这项创新技术。
Introduction The value of simulation in medical education and procedural skills training is well recognized. Despite this, many mannequin-based trainers are limited by the inability of the trainee to view the internal anatomical structures. This study evaluates the usability and feasibility of a first-person point-of-view–augmented reality (AR) trainer on needle insertion as a component of central venous catheter placement. Methods Forty subjects, including medical students and anesthesiology residents and faculty, participated. Augmented reality glasses were provided through which the relevant internal anatomical landmarks were projected. After a practice period, participants were asked to place the needle in the mannequin without the benefit of the AR-projected internal anatomy. The ability of the trainees to correctly place the needle was documented. Participants also completed a short survey describing their perceptions of the AR technology. Results Participants reported that the AR technology was realistic (77.5%) and that the ability to view the internal anatomy was helpful (92.5%). Furthermore, 85% and 82.1%, respectively, believed that the AR technology promoted learning and should be incorporated into medical training. The ability to successfully place the needle was similar between experienced and nonexperienced participants; however, less experienced participants were more likely to inadvertently puncture the carotid artery. Conclusions Results of this pilot study demonstrated the usability and feasibility of AR technology as a potentially important adjunct to simulated medical skills training. Further development and evaluation of this innovative technology under a variety of simulated medical training settings would be an important next step.
