Peritoneal dialysis (PD) is a treatment for kidney failure that uses the peritoneum, a thin sac that surrounds the intestines, as a natural filter. During PD, a special fluid called dialysate is introduced into the abdomen through a small tube called a catheter. Wastes and extra fluid are removed from the blood and passed into the dialysate.
CAPD (Continuous Ambulatory Peritoneal Dialysis) uses a bag of fresh dialysate fluid that is manually connected to the catheter several times a day. The patient conducts 4-5 exchanges over the course of a day. This type of Peritoneal Dialysis gives patients more freedom and flexibility since it does not require a machine. However, it can interfere with sleep and daily routine.
