Simulation provides a safe learning environment where high-stakes, low-frequency procedures can be practiced without the fear of being unsuccessful or causing harm. Emergency department thoracotomy (EDT) is one such procedure. Realistic thoracotomy models are expensive and not readily available.
Our objective is to describe a cost-effective, realistic, reproducible, and reusable thoracotomy model for simulation training.
We modified a commercially available clothes mannequin torso to expose the chest and abdominal cavity. A plastic skeleton composed of a spinal cord and ribs was placed inside the torso. Tubing was used to simulate the aorta and esophagus; both tubes were secured to the distal spine with zip ties. Commercially available lungs and heart were placed inside the chest cavity. A small rubber ball simulated the left lung to be able to maneuver the lung. The heart was covered with plastic wrap to simulate the pericardium. Thick tape was used to simulate the pleural cavity. Yoga mats were used to simulate the intercostal muscles, subcutaneous tissue, and skin.
This model was tested with Emergency Medicine (EM) residents during a simulation session. A voluntary survey was available for residents to provide feedback. Survey results confirmed that the model provided valuable education, with overall positive feedback.
This EDT model provides a valuable teaching opportunity to EM residents who otherwise might not have the opportunity to perform this procedure. Residents agreed that the model improved their confidence and is an effective method in providing the opportunity to practice this low-frequency, high-stakes procedure.
模拟提供了一个安全的学习环境,在这个环境中,可以练习高风险、低频率的操作,而不必担心失败或造成伤害。急诊科开胸手术(EDT)就是这样一种操作。逼真的开胸手术模型价格昂贵且不易获得。
我们的目的是描述一种用于模拟训练的经济高效、逼真、可重复且可重复使用的开胸手术模型。
我们对市售的人体模特躯干进行了改造,以暴露胸腔和腹腔。将由脊髓和肋骨组成的塑料骨架放置在躯干内部。用管道模拟主动脉和食管;两根管道都用束带固定在远端脊柱上。将市售的肺和心脏放置在胸腔内。用一个小橡皮球模拟左肺,以便能够操作肺。心脏用塑料薄膜覆盖以模拟心包。用厚胶带模拟胸腔。用瑜伽垫模拟肋间肌、皮下组织和皮肤。
在一次模拟课程中,该模型由急诊医学(EM)住院医师进行了测试。为住院医师提供了一份自愿调查问卷以收集反馈。调查结果证实,该模型提供了有价值的教育,总体反馈积极。
这个EDT模型为EM住院医师提供了一个宝贵的教学机会,否则他们可能没有机会进行这个操作。住院医师一致认为,该模型提高了他们的信心,是提供机会练习这个低频率、高风险操作的有效方法。
