Needle visualisation during ultrasound-guided procedures is a skill that can be difficult to practise, with commercially available phantoms being expensive and often unrealistic. Our aim was to find an inexpensive, reproducible model that could be used to assist in developing this skill.
Pork shoulder, beef brisket, and lamb shoulder joints were compared to a standard blue ultrasound phantom. Five 'chunky' yarn pieces were twisted together and threaded through each joint to simulate hyperechoic nerves. Participants were instructed to ultrasound each specimen and insert a needle close to a nerve like structure. Using a visual analogue scale, specimens were scored based on realism of appearances of ultrasound images and 'feel' of needling.
38 people participated. All specimens of meat scored significantly higher than the blue phantom (p = 0.01). There was no significant difference between the different types of meat.
Pork, beef and lamb joints are an effective model to use for simulation training for needling skills. They have limited lifespan, but due to its relatively low cost, it is feasible to discard the meat after each training workshop. We hope the use of inexpensive meat products will make ultrasound simulation training simpler to organise and more effective.
在超声引导操作过程中实现针可视化是一项难以练习的技能，市面上的模拟体模价格昂贵且往往不切实际。我们的目的是找到一种廉价、可重复使用的模型，用于辅助培养这项技能。
将猪肩肉、牛腩和羊肩关节与标准蓝色超声模拟体模进行比较。将五根“粗”纱线拧在一起，穿过每个关节，以模拟高回声神经。指导参与者对每个标本进行超声检查，并在类似神经的结构附近插入一根针。使用视觉模拟评分量表，根据超声图像外观的逼真程度和针刺“感觉”对标本进行评分。
38人参与。所有肉类标本的得分均显著高于蓝色模拟体模（p = 0.01）。不同类型的肉之间没有显著差异。
猪、牛和羊的关节是用于针刺技能模拟训练的有效模型。它们的使用寿命有限，但由于成本相对较低，在每次培训工作坊后丢弃肉类是可行的。我们希望使用廉价的肉类产品将使超声模拟训练更易于组织且更有效。
