Peritoneal Dialysis

Overview

Peritoneal dialysis is a home-based dialysis method that uses the peritoneal cavity to filter waste, excess fluids, and toxins from the blood stream. A catheter (a flexible tube), surgically placed near the umbilicus (belly button), facilitates the exchange of dialysis fluid (dialysate).

The process involves filling the peritoneal cavity with dialysate through the catheter (called a dwell), usually for several hours. The lining of the abdominal cavity (the peritoneal membrane) acts as a natural filter, enabling the removal of fluids and waste products. Once the exchange is complete, the used dialysate is drained and replaced with fresh dialysate solution.

Peritoneal dialysis treatments may be done by hand four to five times a day (Known as CAPD) or by using a machine (called a cycler- CCPD/APD) while you sleep. Some people use a cycler at night and also do one or two exchanges during the day.

  • Compared to haemodialysis the Peritoneal dialysis allows more uninterrupted time for work, family, and social activities.
  • Home-based treatment eliminates the need for frequent hospital visits.

  • Requires the patient or a caregiver to be trained in setting up equipment and managing connections
  • May not be suitable for individuals with limited dexterity or support at home.
