Pericardiocentesis is a high-risk/low-frequency procedure important to emergency medicine (EM). However, due to case rarity it is not often performed on a patient during residency training. Because the coronavirus disease 2019 pandemic limited cadaver-based practice, we developed a novel, low-cost, low-fidelity pericardiocentesis model using three dimensional-printing technology to provide advances on prior home-made models.
Residents watched a 20-minute video about performing a pericardiocentesis and practiced both a blind and ultrasound-guided technique. We assessed model fidelity, convenience, and perceived provider competence via post-workshop questionnaire.
A total of 24/26 (93%) individuals practicing on the ultrasound-guided model and 22/24 (92%) on the blind approach model agreed or strongly agreed that the models reasonably mimicked a pericardial effusion.
Our low-cost, low-fidelity model is durable, mimics the clinical case, and is easy to use. It also addresses known limitations from prior low-fidelity models.
心包穿刺术是一项高风险/低频率的程序，对急诊医学（EM）很重要。然而，由于病例罕见，在住院医师培训期间并不经常对患者进行心包穿刺术。由于 2019 年冠状病毒病大流行限制了尸体实践，我们使用三维打印技术开发了一种新型的、低成本、低保真度的心包穿刺模型，该模型在之前的自制模型的基础上有所改进。
住院医师观看了一个关于进行心包穿刺术的 20 分钟视频，并练习了盲法和超声引导技术。我们通过工作坊后的问卷调查评估了模型的逼真度、便利性和感知到的提供者能力。
共有 24/26（93%）名在超声引导模型上练习的人和 22/24（92%）名在盲法模型上练习的人同意或强烈同意模型合理地模拟了心包积液。
我们的低成本、低保真模型耐用、模拟临床病例且易于使用。它还解决了之前低保真模型的已知限制。
