Bacteremia associated with tunneled, cuffed hemodialysis catheters.

A catheter for hemodialysis comprises a flexible catheter tube defining a plurality of separate lumens. The catheter defines an arc angle of generally U-shape in its natural, unstressed configuration. Thus, the catheter may be implanted with a distal catheter portion residing in a vein of the patient, the distal catheter portion being of substantially the shape of the vein in its natural, unstressed condition. Also, a proximal catheter portion resides in a surgically created tunnel extending from the vein and through the skin of the patient, this section of the catheter also being typically in its natural, unstressed condition. Thus blood may be removed from the vein through one lumen of the catheter, and blood may be returned to the vein through another lumen of the catheter, while the catheter is subject to long term indwelling in the body. Improved results are achieved because of the lack of mechanical stress in the shape of the catheter, which stress causes the catheter to press unduly against adjacent tissues.

Successful use of double-lumen, silicone rubber catheters for permanent hemodialysis access.

We describe the long term use for haemodialysis of the PermCath (Quinton, Seattle, Washington) dual lumen, jugular venous catheter (DLJVC) in 21 patients who had no apparent alternative means of access. The nineteen patients maintained in this manner for periods of 30 to 600 days (mean 233.2) included 6 patients dialyzed for over 12 months. Blood flows exceeded 250 mls/min and recirculation rates averaged 5.9%. Infection and insufficiency due to thrombosis were the major problems. In 8 patients (38.1%) infection required DLJVC removal; in three the catheter was immediately replaced over a guidewire along the same track under antibiotic cover and infection has not recurred. Insufficiency occurred in 10 patients (47.6%) and was successfully managed with oral anticoagulants, local instillation of urokinase (4 cases), systemic streptokinase (2 cases) or by changing the DLJVC over a guidewire (2 cases). We believe that the DLJVC is the long term access method of choice for patients in whom conventional access cannot be constructed.
