Instead of Preventing Infections, Silver Coated Needleless IV Connectors May Actually Cause Them, a Nationally-Recognized Expert Tells National Conference on Cancer Nursing Research
Date:2/11/2011

w good it brews."

According to Dr. Chernecky, all three silver coated/impregnated IV connectors tested grew enough Staphylococcus aureus and Staphylococcus epidermidis bacteria to induce infections. She noted a recent FDA Alert & Notification letter which requires manufacturers of positive displacement IV connectors to prove their devices do not increase catheter-related bloodstream infection (CRBSI) risk. Numerous studies already associate positive displacement connecters with higher rates of CRBSI.

Studies also associate negative displacement needleless IV connectors with higher CRBSI rates, she said, due to higher rates of occlusion. Studies have shown that positive and negative displacement connectors appear unable to control bacterial growth, which may be due in part to the bacteria-nurturing effect of blood reflux within the catheter lumen and the dead space within many of the IV connector fluid pathways that entrap blood and are difficult to effectively flush.  

Dr. Chernecky noted in the last 21 years only one new technology-based needleless IV connector has emerged, an intraluminal protection device (IPD) from RyMed Technologies, a company that has been struggling to penetrate a hospital market dominated by older IV connector systems with either positive or negative displacement.  RyMed's device has zero displacement and therefore is not subject to blood reflux, which may help explain its effectiveness in reducing infections to zero or very near zero at hospitals, home infusion and extended care facilities where it's in use. One of the leading hospital-acquired infections, CRBSI is fatal in up to 25% of cases.
