AbstractAlthough catheter-related sepsis (CRS) is an important cause of nosocomial infection and the major complication of intravenous catheter use, there is, as yet, no consensus concerning either a useful definition of CRS or the optimal method of catheter management and prevention of infection. Semiquantitative culture of catheter tips is a useful method of diagnosis of CRS but other techniques such as quantitative catheter blood cultures and Gram staining of the catheter have roles in selected patients. The most significant impact on the prevention of CRS is made by the introduction of an intravenous therapy team. The site and method of catheter insertion, type of dressing and antisepsis, catheter flushing and use of prophylactic antibiotics are also important issues. Techniques such as guide-wire exchange and catheters such as triple lumen and total implantable venous access devices have their own infection problems. Many new and interesting approaches to the prevention of CRS are being formulated. To facilitate further progress, a standardized definition for diagnosis, and revised recommendations for prevention of CRS would be helpful.
