AbstractCentral venous catheter care in parenteral nutrition has been described in numerous publications. These descriptions include care of both short- and long-term catheters. Important aspects in the prevention of infection in central venous catheters used for parenteral nutrition have included: the method of central venous access, subcutaneous tunneling, dressing change techniques, therapeutic uses of the catheter, and catheter-intravenous tubing connection care. Methods of predicting infection and evaluating catheter sepsis have been described. The efficacy of intervention by specialized nutrition support teams in infection control related to these catheters has been demonstrated. Newer partially implantable and completely implantable venous access devices have been used for parenteral nutrition. Methods of infection control and prevention of mechanical damage of these types of catheters have been examined with various results. Care and composition of central venous catheters have been shown to have some role in thrombus formation in the central veins. The use of heparin to prevent thrombosis and catheter occlusion, and the varying degrees of success obtained, have been described. Medical treatment of the occluded catheter with urokinase may be a necessary alternative to discontinuance of that catheter. Overall consideration of research methods used to reach conclusions for catheter care should be considered in the evaluation of appropriate care in each situation.
