Peritoneal Dialysis Peritoneal dialysis utilizes the peritoneal membrane — the lining of the abdominal cavity. The peritoneal membrane is very large and has a rich blood supply. Peritoneal dialysis uses a solution called dialysate that drains into the belly spaces around the intestines and other organs. A small tube (catheter), placed through a minor surgical procedure, carries the dialysate in and out of the belly. The dialysate remains for two to six hours and the wastes, extra fluid and excess chemicals pass from the blood vessels in the peritoneal membrane into the dialysate fluid. Then the dialysate fluid is drained from the belly via the catheter. Once the fluid is drained, new fluid is placed to begin the process anew. Peritoneal dialysis can be performed during the day (CAPD) or with a cycling machine overnight while the patient sleeps. The team that performs peritoneal dialysis in Hyderabad helps patients to become comfortable during the dialysis procedure. The team is available 24 hours to assist patients.
