Vascular access is an essential and rate-limiting step during pediatric resuscitation efforts. Intraosseous (IO) access, an effective resuscitative strategy, remains underutilized in emergency departments. Many medical graduates report never performing the procedure before graduation, and it has been recommended that continuing education and in-servicing programs be implemented to increase the use and familiarity of IO access. The goal of this technical report is to describe the development and evaluation of a three-dimensional (3D)-printed Pediatric IO Infusion Model for simulation-based medical education. The simulator was designed by combining open-source models of a human skeleton and a lower leg surface scan in Blender (Blender Foundation, Amsterdam, Netherlands; www.blender.org), scaled to a pediatric size, and manipulated further using a JavaScript program. Polylactic acid was used to simulate bone while silicone molds were used as skin and soft tissue. Two trainers were produced and evaluated by seven emergency medicine physicians, two family medicine residents, and three medical students. Overall, the simulator was positively received with all participants indicating they would recommend it to assist in the training of others. Suggestions focused on enhancing the anatomical representations of both the skin and bones to enhance the learner experience. The content and outcomes of this report support the use of this simulator as part of simulation-based medical education.
血管通路是儿科复苏过程中的一个关键且限制速度的步骤。骨内（IO）通路作为一种有效的复苏策略，在急诊科的应用仍然不足。许多医学毕业生报告称在毕业前从未进行过该操作，因此有人建议实施继续教育和在职培训项目，以增加IO通路的使用并提高对其的熟悉程度。本技术报告的目的是描述一种用于基于模拟的医学教育的三维（3D）打印儿科IO输液模型的开发和评估。该模拟器是通过在Blender（荷兰阿姆斯特丹的Blender基金会；www.blender.org）中结合人体骨骼的开源模型和小腿表面扫描数据设计而成，按儿科尺寸缩放，并使用JavaScript程序进一步处理。聚乳酸用于模拟骨骼，而硅胶模具用作皮肤和软组织。制作了两个训练模型，并由七名急诊医学医生、两名家庭医学住院医师和三名医学生进行评估。总体而言，该模拟器获得了积极评价，所有参与者都表示会推荐它来帮助培训其他人。建议集中在增强皮肤和骨骼的解剖学表现，以提升学习者的体验。本报告的内容和结果支持将该模拟器用作基于模拟的医学教育的一部分。
