A Randomized Controlled Study to Determine Whether Smaller Gauge Fenestrated Catheters Are as Effective as Larger Gauge Non-fenestrated Catheters for Use in IV Contrast Enhanced CT Scans
In Brief
A clinical study evaluating 20GA BD Nexiva Diffusics and 18GA Conventional Catheter for Contrast Enhanced Computed Tomography. Completed, enrolled 238 participants across 1 site.
Detailed Summary
The purpose of this study is to compare multidetector computed tomography (CT) image quality following peripheral venous high pressure injection of iodinated intravenous contrast media between a 20 gauge (GA) fenestrated, intravenous catheter (BD Nexiva™ Diffusics™) and an 18 GA non-fenestrated, intravenous catheter. In the contrast enhanced CT procedure (CECT), a machine (power injector) is used to rapidly deliver contrast agent to an individual's circulatory system. The contrast allows for greater differentiation of tissues in images of the area of interest, affording a better opportunity to visually assess the area and hence make a more accurate diagnosis. CECT often requires a high rate of contrast flow (≥ 5 mL/sec) through the IV catheter to provide sufficient contrast for an acceptable image. Typically an 18 GA IV catheter is required to achieve these high flow rates; however, often the patient does not have a vein that will accommodate this large size catheter. The BD Nexiva™ Diffusics™ IV catheter is designed to deliver a higher flow rate than a conventional catheter of the same gauge by incorporating fenestrations (small openings) near the tip of the catheter that allow fluid to exit the catheter in addition to that which normally exits through the main opening at the tip of the catheter.

Interventions
The Inserter will have a single attempt on each arm (antecubital area) in which to insert the study catheter. If the catheter is not successfully inserted on the first attempt, the Inserter may make a second attempt in the contralateral arm. If the Inserter is unsuccessful in the second attempt, the subject is to be discontinued from the Study, and additional (non-Study) insertion attempts may be made according to facility policies.

If after the first attempt, there is no vein in the contralateral arm that can accommodate an 18 gauge catheter, the subject is to be discontinued from the Study, and additional (non-Study) insertion attempts may be made according to facility policies.
