Intravenous catheterization is a common practice for administering fluids directly into the blood stream. It is often associated with a lethal and a very frequent complication of Catheter-related bloodstream infection (CRBSI).

Catheter-related bloodstream infections (CRBSI) are defined as the presence of bacteraemia originating from an intravenous catheter. CRBSIs are a leading cause of nosocomial infections associated with morbidity, mortality, and cost.
