Limited data exist regarding the echogenicity of perineural catheters, but visualization is crucial to ensure accurate placement and efficacy of the subsequent local anesthetic infusion. The objective of this study was to determine the comparative echogenicity of various regional anesthesia catheters. In an in vitro porcine-bovine model, we compared the echogenic qualities of 3 commercially available regional anesthesia catheters and 1 catheter under development to optimize echogenicity. Outcomes included visual echogenicity ranking, image quality, and scanning time, as assessed by 2 blinded investigators. The experimental catheter was found to be more echogenic than 2 of the 3 comparators.
关于神经周围导管的回声性，现有数据有限，但可视化对于确保后续局部麻醉剂输注的准确放置和效果至关重要。本研究的目的是确定各种区域麻醉导管的相对回声性。在体外猪-牛模型中，我们比较了3种市售区域麻醉导管和1种正在研发以优化回声性的导管的回声特性。由2名盲法研究者评估的结果包括视觉回声性排名、图像质量和扫描时间。发现实验导管的回声性高于3种对照导管中的2种。
