Randomized Controlled Trial
The Impact of Peripheral Intravenous Catheter Insertion Technique and Catheter-to-Vein Ratio on Postinsertion Failure.
Peripheral intravenous catheter (PIVC) postinsertion failure rates are unacceptable. Ultrasonography is an adjunctive tool that may improve PIVC utilization success. ⋯ The USG technique did not decrease postinsertion failure rate, increase utility time, or significantly decrease postremoval complication rate. A CVR predictive of postinsertion failure could not be determined.
