ReviewPlacement and management of long-term central venous access catheters and ports.
Recent developments in long-term central venous access devices, access techniques, and the management of complications are described. Factors used in selecting a device include the intensity and frequency of therapy and the preferences of the patient. Implantable ports and external catheters are available with valved (Groshong) and nonvalved catheters and with single or multiple lumens. ⋯ An infected catheter can be diagnosed without catheter removal by comparison of quantitative blood cultures from the catheter and peripheral vein. Early recognition of catheter-related infection may save the catheter. Removal of an infected catheter depends on the nature of the offending agent, severity of infection, success of treatment, and degree of difficulty in obtaining alternative access.
