419 Extended Length Peripheral Catheters Placed Under Ultrasound Guidance Are Associated With Increased Risk of Computed Tomography Contrast Extravasation

Study Objectives: Ultrasound guided intravenous catheter (USGIV) placement is a safe and effective alternative for traditional vascular access in patients with known difficult intravenous (IV) access. However, multiple studies have shown increased risk of computed tomography (CT) contrast extravasation. These studies are retrospective and did not control for the USGIV catheter length. This study assesses the risk of CT contrast extravasation through 2.5-inch 18-gauge USGIV versus standard 1.16-inch catheters placed by traditional landmark technique.
