The erector spinae plane (ESP) block is an increasingly utilized regional block in the emergency department, representing one effective alternative or adjunct to opioid analgesia in patients presenting with rib fractures. While there is growing interest, its widespread adoption faces hurdles, such as a lack of appropriate training resources. Gelatin-based phantoms to simulate human anatomy have been widely used to facilitate ultrasound-guided procedures, although no such model for the ESP block has yet been defined in the literature. To address this gap, we sought to design and assemble an inexpensive, simple to build, reusable phantom to simulate the sonographic anatomy of the posterior thoracic wall and serve as a task trainer for an ultrasound-guided ESP block. This novel phantom model reproduces an ultrasonographic fascial plane using a gelatin medium and 3D-printed thoracic spine with ribs allowing for needle guidance and hydrodissection.
竖脊肌平面（ESP）阻滞在急诊科中是一种越来越常用的区域阻滞方法，它是治疗肋骨骨折患者的一种有效替代或辅助阿片类药物镇痛的方法。尽管人们越来越感兴趣，但它的广泛应用面临着一些障碍，例如缺乏适当的培训资源。基于明胶的体模已被广泛用于辅助超声引导操作，但ESP 阻滞尚无文献报道的此类模型。为了弥补这一空白，我们设计并组装了一种经济实惠、易于构建、可重复使用的体模，以模拟胸后壁的超声解剖结构，并作为超声引导 ESP 阻滞的任务培训器。该新型体模使用明胶介质和带有肋骨的 3D 打印胸椎来再现超声筋膜平面，从而实现了针的引导和水分离。
