Prospective evaluation of a double-lumen subclavian dialysis catheter for acute vascular access.

The safety and efficacy of a parallel, double-lumen hemodialysis catheter used to achieve acute, temporary vascular access were evaluated prospectively in 134 hospitalized adult patients in whom 162 catheters were placed. The arterial flow rates and venous resistance were such that 84 per cent of the catheters provided satisfactory access for dialysis. Minor manipulations of the catheter were frequently required to maximize function. Three serious complications occurred, including one instance each of pneumothorax, hemorrhage, and nonfatal pericardial tamponade.
