Abstract
A central venous (W-B-W) catheter has been developed for vascular access in children of all ages and sizes. The catheter design and implantation technique permit nonsurgical bedside adjustment of catheter position and ease of removal. Multiple possible uses include intravenous fluid administration, blood sampling, central venous pressure monitoring, and plasma exchange therapy in addition to hemodialysis. Twenty-seven W-B-W catheters were placed in 24 patients in a 12-month period. The catheter provided adequate blood flow for hemodialysis. Seven catheters were removed nonelectively in five patients. One episode of catheter-associated sepsis occurred after renal transplantation in a patient on immunosuppressive therapy. It is concluded that the W-B-W catheter is a relatively safe, multipurpose, pain-free acute vascular access for children, which may also suffice for chronic hemodialysis.
