Abstract
Introduction: Ultrasound-guided intravenous (USIV) cannulation is a common alternative when IV access cannot otherwise be obtained. Many hospitals teach this skill with the commercial CAE Blue Phantom gelatinous training blocks. However, their cost is a barrier. This has led to experimentation with creative alternatives. Recent studies have trialed SCOBY (Symbiotic Culture of Bacteria and Yeast) in the production of training models for medical procedures. SCOBY is a biofilm-like structure appearing as a thick, rubbery film. We aimed to develop a 2-vessel SCOBY-based model and compare its effectiveness for teaching USIV against the Phantom.
Methods: Participants, 23 emergency medicine clinicians, performed USIV on each model and completed a pre- and post-procedure questionnaire.
Results: Seventy-four percent of participants indicated that the SCOBY model more closely resembled the clinical reality of human tissue compared with 13% for the Phantom. SCOBY provided an improved visual appearance, physical touch, feel of the procedure, and appearance of "subdermal tissues" on ultrasound compared to the Phantom.
Conclusion: These results suggest a promising future for SCOBY as a cost-effective alternative to teaching clinical skills.
导读：超声引导静脉（USIV）插管是一种常见的选择，当静脉访问不能以其他方式获得。许多医院用商用CAE Blue Phantom凝胶训练块教授这项技能。然而，它们的成本是一个障碍。这导致了创造性替代方案的试验。最近的研究已经试验了SCOBY（细菌和酵母的共生培养）在医疗程序训练模型的生产。SCOBY是一种类似生物膜的结构，看起来像一层厚厚的橡胶膜。我们的目标是开发一个基于scoby的2船模型，并比较其与Phantom的教学USIV的有效性。方法：23名急诊临床医生对每个模型进行USIV测试，并完成术前和术后问卷调查。结果：74%的参与者表示SCOBY模型更接近临床真实的人体组织，而幻影模型只有13%。与Phantom相比，SCOBY提供了更好的视觉外观、物理触感、手术感觉和超声“皮下组织”外观。结论：这些结果表明，SCOBY作为一种具有成本效益的替代临床技能教学方法具有广阔的前景。
