Application of Echogenic Technology for Catheters Used in Ultrasound-Guided Continuous Peripheral Nerve Blocks JOURNAL OF ULTRASOUND IN MEDICINE Mariano, E. R., Yun, R. D., Kim, T. E., Carvalho, B. 2014; 33 (5): 905-911

Abstract

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.
