Peritoneal Dialysis & IPD

CHP. 13. Dialysis 73.

Peritoneal dialysis (PD) is another form of dialysis modality for the patients with kidney failure. It is widely accepted and effective. It is the most common method of dialysis done at home.

What is peritoneal dialysis?

  • The peritoneum is a thin membrane that lines the inner surface of the abdominal cavity.
  • The peritoneal membrane is a natural semi-permeable membrane which allows waste products and toxins in the blood to pass through it.
  • Peritoneal dialysis is a process of purification of blood through the peritoneal membrane.

What are the types of peritoneal dialysis?

Types of peritoneal dialysis:

  1. Intermittent Peritoneal Dialysis (IPD)
  2. Continuous Ambulatory Peritoneal Dialysis (CAPD)
  3. Continuous Cycling Peritoneal Dialysis (CCPD)

1. Intermittent Peritoneal Dialysis (IPD)

Intermittent peritoneal dialysis (IPD) is a valuable and effective dialysis option for short term dialysis in hospitalized patients with acute kidney failure, in children and during emergencies or initial treatment of ESKD. In IPD, a special catheter with multiple holes is inserted into the patient’s abdomen through which a special solution called the dialysate is infused into the abdominal cavity or peritoneal space. The dialysate absorbs waste products and excess fluids from the patient’s blood. After some time, the fluid is drained and the process is repeated several times in a day.

  • IPD lasts for a period of 24- 36 hours and about 30 to 40 liters of dialysate solution is used up during the treatment.
  • IPD is repeated at short intervals of 1 -3 days, as per the need of the patient.
CAPD is a type of dialysis that can be carried out by patients at home with specialized fluid.
