Hemodialysis

The most common treatment of advanced and permanent kidney failure is hemodialysis. It is a procedure of external purification of blood (from the wastes and extra fluids) in case patient’s kidneys stop working. The blood is transported through a tube to the dialyzer (dialysis machine), where a special filter removes harmful substations from it. Then the purified blood is returned to the body (through a second tube). In hemodialysis treatment, procedures are usually performed several times a week and take 3 – 5 hours each.

The dialyzer is connected to the patient’s body by needles inserted by vascular access. There are two types of vascular access designed for long-term use: the arteriovenous (AV) fistula and the AV graft. There can be used also a third type of vascular access which is dedicated to short-term use – access through venous catheter.

The first type of access is usually located in the forearm of the non-dominate arm. The second type is located on the arms and more seldom in the vicinity of thigh or thorax. After the procedure, the punctured place has to be pressed in order to create haemostasis to stop the bleeding. Dia Stop is specially designed for this purpose. It is applicable for puncture sites created in the forearm.
