Abstract

Purpose: To develop a pericardiocentesis (PCT) simulation model applied for undergraduate medical training.

Methods: A PCT simulator consisted of a torso mannequin, a silicone rubber heart (SRH), a container, and a filling system. The mannequin was submitted to a coronal section and an 18 × 18-cm precordial area opening. The SRH was prepared in accordance with structural dimensions of a normal heart. The elaboration of a structure container to simulate the pericardial cavity consisted of a non-leakable unit inside a cardboard (PcavBox). The PcavBox filling system was connected to a 10-mm diameter tube and a total of 2.5 L of saline solution. This structure was adapted inside the mannequin and covered with a thermoformable rubber material of 2 mm in skin color. For PCT simulation, we used a 10-mL syringe connected to a 14G needle for an imaging guided puncture facilitated by a portable ultrasound.

Results: A SRH was successfully developed and fixed inside the Pcav Box, connected to the fluid pressure system. It was able to simulate a cardiac tamponade scenario identified by ultrasound. A series of 50 punctures was successively performed without liquid leak.

Conclusion: A low-cost PCT simulator was developed and coan be applied to healthcare education.

心包穿刺模拟模型:构想与发展。
目的:建立适用于本科医学培训的心包穿刺术(PCT)仿真模型。方法:PCT模拟器由躯干人体模型、硅橡胶心脏(SRH)、容器和填充系统组成。将人体模型置于冠状面切片和18 × 18 cm心前区开口。按照正常心脏的结构尺寸制备SRH。设计了一种结构容器来模拟心包腔,该容器由纸板内的不泄漏单元组成(PcavBox)。PcavBox填充系统连接到直径10mm的管和总共2.5 L的生理盐水溶液。这种结构被安装在人体模型内部,并覆盖了一层皮肤颜色为2毫米的可热成型橡胶材料。对于PCT模拟,我们使用10ml注射器连接14G针,在便携式超声的帮助下进行成像引导穿刺。结果:成功研制出SRH,并将其固定在Pcav盒内,与流体压力系统相连。它能够模拟由超声识别的心脏填塞情况。连续穿刺50次,无漏液。结论:研制了一种低成本的PCT模拟器,可用于健康教育。
