An in vitro comparison of intraluminal biofilm bacteria transfer of three peripheral intravenous valved blood control catheters

Abstract

The insertion of peripheral intravenous catheters (PIVC) is the most common invasive procedure performed by nurses. The new generation of PIVCs developed to reduce blood exposure during insertion utilizes additional internal components within the catheter hub. These components increase the internal surface area that is thought to increase biofilm formation and subsequent transfer of bacteria into the bloodstream. This raises concern for increased risk of bloodstream infection. The purpose of the this study is to compare biofilm formation and bacterial transfer rate between 3 valved blood control PIVCs in a clinically simulated in vitro model.
