To validate the newly designed ultrasound-guided suprapubic catheter insertion trainer (US-SCIT) model against the real life experience by enrolling participants with prior confidence in the technique of US-guided suprapubic catheter (SPC) insertion.
The US-SCIT was self-constructed from common disposables and equipment found in the emergency department. A validation questionnaire was completed by all participants after SPC insertion on the US-SCIT model.
Fifty participants enrolled in the study. Each participant had reported confidence in the SPC insertion technique, prior to participation in this study. There were 13 "super-users" (>65 previous successful real life SPC insertions) in the study. The total material cost per US-SCIT unit was 1.71 USD. The US-SCIT's value in understanding the principals of US-guided SPC insertion had a mean score of 8.86 (standard deviation [SD] 1.03), whereas its value in simulating contextual anatomy had a mean score of 8.26 (SD 1.48). The mean score of the model's ability to provide realistic sensory feedback was 8.12 (SD 1.78), whereas that of realism of initial urine outflow was 9.06 (SD 1.20). Simulation with the model compared well with real life SPC insertion, with a mean score of 8.30 (SD1.48).
The US-SCIT model performed well in various spheres developed to assess its ability to simulate real life SPC insertion. We are confident that this low-cost, validated, US compatible SPC trainer, constructed from common material present in the ED, will be a valuable learning asset to trainees across the globe.
通过招募对超声引导下耻骨上膀胱造瘘管（SPC）插入技术有信心的参与者，将新设计的超声引导下耻骨上膀胱造瘘管插入训练器（US-SCIT）模型与实际经验进行验证。
US-SCIT由急诊科常见的一次性用品和设备自行构建。所有参与者在US-SCIT模型上进行SPC插入后完成一份验证问卷。
50名参与者纳入研究。每位参与者在参与本研究之前都表示对SPC插入技术有信心。研究中有13名“超级用户”（之前在实际生活中成功进行SPC插入超过65次）。每个US-SCIT装置的总材料成本为1.71美元。US-SCIT在理解超声引导下SPC插入原理方面的价值平均得分为8.86（标准差[SD]1.03），而在模拟相关解剖结构方面的价值平均得分为8.26（SD 1.48）。该模型提供逼真感觉反馈能力的平均得分为8.12（SD 1.78），而初始尿液流出逼真度的平均得分为9.06（SD 1.20）。该模型的模拟与实际生活中的SPC插入效果良好，平均得分为8.30（SD1.48）。
US-SCIT模型在为评估其模拟实际生活中SPC插入能力而开发的各个方面表现良好。我们相信，这种由急诊科常见材料构建的低成本、经过验证且与超声兼容的SPC训练器，将成为全球学员宝贵的学习资源。
