Hemodialysis and Peritoneal Dialysis
Hemodialysis and peritoneal dialysis are both used to remove wastes and other toxic substances from the blood when the kidneys are unable to do so.
Hemodialysis uses a man-made membrane called a dialyzer to filter wastes and remove extra fluid from the blood. The blood is circulated through the dialyzer and then re-routed back into the body via a catheter or permanent access port. This is performed at a specialized facility about three times a week.
Peritoneal dialysis uses the lining of the abdominal cavity (peritoneal membrane) and a solution (dialysate) to remove wastes and extra fluid from the body.
