AbstractVisualization of the catheter during ultrasound-guided continuous nerve block performance may be difficult but is an essential skill for regional anesthesiologists. The objective of this in vitro study was to evaluate 2 newer catheters designed for enhanced echogenicity and compare them to a widely used catheter not purposely designed for ultrasound guidance. Outcomes were the numbers of first-place rankings among all 3 catheters and scores on individual echogenicity criteria as assessed by 2 blinded reviewers. Catheters designed for echogenicity are not superior to an older regional anesthesia catheter, and results suggest that catheter preference for ultrasound-guided placement may be subjective.© 2017 by the American Institute of Ultrasound in Medicine.
