Abstract

Objectives

Lumbar puncture (LP) simulators have high costs and suboptimal realism. This study aimed to develop an affordable, high-fidelity and ultrasound-compatible model.

Methods

We created a LP Simulator using three-dimensional printing, silicon, ballistic gel and symbiotic culture of bacteria and yeast (SCOBY). This was an observational study comparing the DIY-LP to a commercial simulator. Pre- and post-surveys were done.

Results

A total of 18 emergency medicine doctors (12 junior and six senior) participated in the study. Ten participants (56%; five junior doctors and five consultants) were successful with the DIY-LP simulator within the first two attempts without ultrasound guidance, compared with 13 participants (72%; seven junior doctors and six consultants) for the commercial simulator (p-value 0.49). The majority of participants agreed that both models were useful as educational tools.

Conclusion

This study has demonstrated a low-cost and ultrasound-compatible LP model that is comparable to a commercial LP simulator.

使用SCOBY作为有效模拟工具的廉价且超声兼容的腰椎穿刺模型：DIY LP研究

目的腰椎穿刺（LP）模拟器成本高，真实感欠佳。本研究旨在开发一种经济、高保真和超声兼容的模型。方法采用三维打印、硅、弹道凝胶和细菌与酵母共生培养（SCOBY）制备LP模拟器。这是一项观察性研究，将DIY-LP与商业模拟器进行比较。进行了前后调查。结果共有18名急诊医师（初级12名，高级6名）参与研究。10名参与者(56%；5名初级医生和5名咨询医生)在没有超声引导的情况下，在前两次尝试中使用DIY-LP模拟器成功，而13名参与者(72%；7名初级医生和6名顾问)用于商业模拟器（p值0.49）。大多数与会者同意这两种模式都是有用的教育工具。本研究证明了一种低成本和超声兼容的LP模型，可与商用LP模拟器相媲美。
