摘要：

Background: Vascular access is a critical skill for emergency physicians. However, it can be unpredictably challenging in some patients. While ultrasound-guided vascular access has been encouraged in emergency departments, there have been few studies evaluating echo-enhanced needles and their usefulness in performing vascular access. Aims: Our purpose was to determine if the use of an echoenhanced needle tip results in faster vascular access times, with fewer needle sticks, fewer redirections, and improved needle visualization in ultrasound-guided vascular access with the vessel in the short axis. Methods: This is a prospective, randomized, observational study of ultrasound-guided vascular access on a vascular phantom comparing an echo-enhanced needle with a standard needle. Each participant viewed a teaching video demonstrating typical ultrasound-guided vascular access and then attempted ultrasound-guided vascular access using both a standard and an echo-enhanced needle with the vessel in the short axis. The numbers of needle sticks, redirections, and time to dye flash were measured. Results The 69 participants attempted 69 short-axis ultrasound-guided vascular cannulations with no difference in time to dye flash between needle types: the median time from needle stick to flash was 17.56 s [interquartile range (IQR): 12.37-33.15] for the standard needle and 19.22 s (IQR: 10.19-31.10) for the echo-enhanced needle. There was no difference between needle types for number of needle sticks or redirects. Conclusion: Echo-enhanced needles did not provide objective performance improvement compared to standard needles during ultrasound-guided vascular access with a vascular access model in the short axis. © Springer-Verlag London Ltd 2009.
