What is
blood filtering (dialysis)?
The kidneys normally remove waste products from the bloodstream.
When the kidneys fail, dialysis is substituted to remove the toxins
or poisons that build up. This procedure requires the patient to
have a special central venous catheter specifically made for
dialysis. Blood circulates from the body through the dialysis
machine, where it is filtered, and back into the body. Dialysis can
be performed in the ICU or in the dialysis unit depending upon the
condition of the patient. It takes approximately four hours to
perform and is administered approximately three times a week.
Are there different types of dialysis?
There are several types of dialysis, for example: blood filtering (hemodialysis),
a form of blood filtering called CHVVD (venous dialysis), and
abdominal filtering (peritoneal dialysis).
How long is dialysis used?
Dialysis can be used for a few days or for years - it depends on the
patient's condition and the cause of the patient's kidney failure.
Does dialysis hurt?
Not usually. A special type of central venous
catheter, which may cause minor discomfort, is often inserted to
perform
hemodialysis. The dialysis itself does not hurt. However, some
patients feel fatigued following a dialysis treatment.
Are there any potential complications
associated with dialysis?
There are extensive potential complications associated with
dialysis, some of which are very serious. These are best
discussed with your doctor or nurse.
