The purpose of this study was to compare sonographically guided vascular access using standard and echo-enhanced needles in a variety of tissue-simulating vascular phantoms. ⋯ Echo-enhanced needles decreased the incidence of posterior wall punctures when compared to standard needles during sonographically guided vascular access. However, there were no significant differences in other sonographically guided vascular access metrics.
