Abstract:
Catheters are generally known to be the last resort for blood access in dialysis. Because of the many problems related to catheter use, catheters are banned from vascular access courses organized by professional societies and the development of catheters and catheter related equipment relies on a few interested medical doctors with limited knowledge of hydraulics and material science. Rather than accepting the need for catheters and the need for improving catheters and catheter related procedures, vascular access meetings typically begin and end with statements saying that the use of fistulas must be increased and catheters must be banned. Several small companies have developed new catheters and catheter related equipment, which potentially overcome many of the problems related to the use of catheters. The authors had the privilege of participating in one of these developments and report about basic features and clinical experience of the DIALOCK blood access port and an antimicrobial catheter locking solution (CLS) which is used with conventional catheters as well as with the DIALOCK.
