Simulation experiences are valuable to the training of future successful surgeons. These experiences introduce trainees to operational concepts through hands-on engagement within a low-stress environment to promote skill, information retention, and increased competency for future success in real-life scenarios. The study aimed to develop a low-cost, reproducible surgical simulation for teaching aortic valve replacement using porcine models. This study employed a single-center educational workshop design to provide trainees with a comprehensive wet laboratory experience in surgical aortic valve replacement using a porcine model. The simulation involved step-by-step procedures using porcine hearts in a wet lab environment, emphasizing specific surgical techniques such as suturing, knot tying, and valve replacement. Simulated valves were created using insulation foaming and aluminum wiring. The study was conducted at a southeastern medical school's wet lab. Thirty-eight preclinical medical students participated. The simulation was designed to provide a comprehensive overview of the steps involved in aortic valve replacement using porcine models. It emphasized the importance of teamwork, fundamental surgical skills, and effective communication within a surgical setting. The low-cost surgical simulation allowed trainees to learn technical skills that could be tailored to their proficiency level. Simulation for cardiothoracic procedures is limited by monetary spending and the availability of adequate materials to create a beneficial learning experience. This low-cost simulation allows resource-limited institutions to provide their students an additional opportunity to practice fundamental surgical principles such as suturing.
模拟体验对于培养未来成功的外科医生很有价值。这些体验通过在低压力环境中的实践操作，向学员介绍手术概念，以提升技能、增强信息留存能力，并提高在现实场景中取得成功的能力。该研究旨在开发一种低成本、可重复的使用猪模型进行主动脉瓣置换教学的手术模拟。本研究采用单中心教育工作坊设计，为学员提供使用猪模型进行主动脉瓣置换手术的全面湿实验室体验。该模拟在湿实验室环境中使用猪心脏进行逐步操作，强调缝合、打结和瓣膜置换等特定手术技术。模拟瓣膜使用绝缘泡沫和铝线制作。该研究在东南部一所医学院的湿实验室进行。38名临床前医学生参与其中。该模拟旨在全面概述使用猪模型进行主动脉瓣置换所涉及的步骤。它强调了团队合作、基本手术技能以及手术环境中有效沟通的重要性。这种低成本的手术模拟使学员能够学习可根据其熟练程度进行调整的技术技能。心胸外科手术模拟受到资金支出和用于创造有益学习体验的足够材料可用性的限制。这种低成本模拟使资源有限的机构能够为其学生提供额外机会来练习诸如缝合等基本手术原则。
