The Impact of Peripheral Intravenous Catheter Insertion Technique and Catheter-to-Vein Ratio on Postinsertion Failure.

Background: Peripheral intravenous catheter (PIVC) postinsertion failure rates are unacceptable. Ultrasonography is an adjunctive tool that may improve PIVC utilization success.

Objectives: Determine if ultrasonographically guided (USG) PIVCs placed in the emergency department (ED) significantly decreases postinsertion failure rate, increases utility time, and decreases postremoval complication rate.
