Project Summary

Peripheral intravenous catheters (PIVCs) are small plastic tubes placed in a patient’s vein for the delivery of intravenous fluid and medications. In the emergency department, many patients present with difficult intravenous access and require multiple insertion attempts to successfully place a PIVC. This can be time consuming for clinical staff, costly for hospitals, and painful for patients. Correct device selection is a key strategy to ensure first-time insertion success.

This study will recruit 406 adult participants at two emergency departments in order to test if novel PIVCs with a retractable guidewire (AccuCath Ace™ Intravascular Cannula, BD), compared to standard care, are effective at increasing first-time insertion success for patients with difficult vascular access.
