Peritoneal Dialysis
A fluid is put into your abdomen. This fluid, called dialysate captures the waste products from your blood. After a few hours, the dialysate containing your body's waste is drained away. Then, a fresh bag of dialysate is dripped into the abdomen. Patients can perform peritoneal dialysis themselves. Patients using Continuous Ambulatory Peritoneal Dialysis (CAPD), the most common form of peritoneal dialysis, change dialysate four times a day. Another form of peritoneal dialysis, however, can be performed at night with a machine that drains and refills the abdomen automatically.
