What is Peritoneal Dialysis
Peritoneal Dialysis (PD) is a treatment for kidney failure. A special sterile fluid is introduced into the abdomen through a permanent tube that is placed in the peritoneal cavity. The fluid circulates through the abdomen to draw impurities from surrounding blood vessels in the peritoneum (abdominal cavity), which is then drained from the body.
There are 2 types of PD – Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD). PD gives patients more flexibility and control over their lives. NKF provides various community support services to ensure PD patients start and stay well on PD. Patients and his/her family need to work closely with the health care team to achieve the best possible results and continue to lead an active life.
Frequently Asked Questions
A permanent catheter will be placed in the abdominal cavity.
Continuous Ambulatory Peritoneal Dialysis (CAPD) is done during the day and machine-free. The process is carried out using the PD bag system, and gravity to fill and empty the abdomen. The doctor will prescribe the number of exchanges a patient needs, typically three or four exchanges during the day and one evening exchange. The replacing of fresh PD solution with the used PD solution is called an exchange.
The patient can walk around with the dialysis solution in the abdomen. No exchange is required while the patient is sleeping.
PD can be carried out at home, at work, or on trips, but requires careful supervision.
Painless and No Needling
- Unlike HD, no vascular access or needling is required for PD, hence PD is a painless procedure.
- Vascular access-related complications are one of the common causes of hospitalisation in haemodialysis patients.
- Patients carry out treatment themselves in the comfort of their own homes.
- No need to travel to the dialysis centre for treatment and not restricted to dialysis centres’ schedule.
- More flexibility to better fit dialysis into their lifestyle.
Patients take charge their own treatment plan and advice given by the PD care team.
Gentler and works more like the natural kidney
- PD mimics the function of real kidneys more as the constant presence of the PD solution in the abdominal cavity allows waste products and excess water from the blood to be removed continuously.
- The non-intermittent nature of PD makes it a gentler treatment. Patients have lesser food restrictions and experience lesser side effects.
