simulation based teaching is a powerful tool in medical education, allowing hands on practice under a controlled environment and with repeated maneuvers. Central venous access venipuncture is one of the most frequent procedures carried out in the hospital setting, due to its various clinical indications and, when performed with the help of ultrasonography, the risk of adverse events is minimized. Aim: to develop, to describe and to test a porcine model that simulates the central venous access puncture aided by ultrasonography.
a low cost porcine model was developed to train medical students and residents on central venous access guided by ultrasonography. Both students and medical residents underwent a theoretical training regarding the model, followed by a hands-on training session. Afterwards, the participants assessed the model by answering a questionnaire.
there were 51 participants. The average score regarding the similarity between the model and the human anatomy was 9.15. When the characteristics were separately assessed, the mean scores regarding the similarity of the vessels, anatomic disposition and ultrasonographic characteristics as well as the venipuncture were, respectively, 9.27; 9.31; 9.54 and 8.86.
The model was approved and considered appropriate for the training of central venous venipuncture by all the participants. Furthermore, it is a low cost, simple and reproducible model, that presents high similarity with the human anatomy. Therefore, it may be used as an aid to train people on ultrasonography guided central venous access.
基于模拟的教学是医学教育中的一种强大工具，它能在可控环境下通过反复操作实现实践练习。中心静脉穿刺置管是医院环境中最常进行的操作之一，因其具有多种临床适应证，并且在超声引导下进行时，不良事件的风险可降至最低。目的：开发、描述并测试一种模拟超声辅助中心静脉穿刺置管的猪模型。
开发了一种低成本的猪模型，用于培训医学生和住院医师进行超声引导下的中心静脉穿刺置管。学生和住院医师都接受了关于该模型的理论培训，随后进行了实践培训课程。之后，参与者通过回答问卷对模型进行评估。
共有51名参与者。关于模型与人体解剖结构相似性的平均得分为9.15。当分别评估各特征时，血管、解剖位置、超声特征以及静脉穿刺相似性的平均得分分别为9.27、9.31、9.54和8.86。
该模型得到了所有参与者的认可，并被认为适用于中心静脉穿刺置管的培训。此外，它是一种低成本、简单且可重复的模型，与人体解剖结构具有高度相似性。因此，它可作为辅助工具用于培训人们进行超声引导下的中心静脉穿刺置管。
