Abstract:
A new vascular access catheter has been developed (Cook Critical Care, Bloomington, IN) that is suitable for both short-term and long-term hemodialysis. Designed primarily for the internal jugular vein, it emerges through a subcutaneous tunnel on the anterior chest wall. With parallel cylindrical lumens to provide blood flows of 400 mL/min, it is compressible during insertion and can be placed percutaneously in the vein through a 13-French peel-away sheath. This allows repeated insertions at different times in the same patient. In 80 catheter insertions, we have found one case of jugular vein thrombosis attributable to the catheter and no subclavian vein thrombosis. After 15 months of use, the bloodstream infection rate was one per 19.7 patient-months. Using this device, it should be possible to stop the subclavian vein damage and perforating injuries that have been the most important complications of semistiff, tapered, subclavian catheters.
