Overview
Peritoneal dialysis is a home-based treatment that removes waste and extra fluid from the body when the kidneys aren't working properly. Peritoneal dialysis uses the lining of the abdomen (the peritoneum) as a natural filter, while hemodialysis uses a machine to filter blood. A soft catheter that has been surgically placed in the abdominal cavity allows a special cleaning fluid called dialysate to enter. The blood vessels in the peritoneal lining send waste and extra fluid into the dialysate, which is then drained and replaced. There are two main types: Automated Peritoneal Dialysis (APD) and Continuous Ambulatory Peritoneal Dialysis (CAPD).
Why It's Done
People with chronic kidney failure who need long-term dialysis support get peritoneal dialysis. It gives you a choice besides hemodialysis and lets you do it at home or on the go. The procedure helps maintain fluid balance, eliminate toxins, control blood pressure, and maintain stable electrolyte levels. Patients who want to be more in control of their treatment often choose it.
What to Expect?
Before starting peritoneal dialysis, a small surgery is done to put a catheter into the abdomen. The site has to heal before dialysis can start. Patients and caregivers learn how to use sterile techniques and perform exchanges safely. Dialysate is manually put into the abdomen several times a day during CAPD and left there for a few hours before being drained. During APD, a machine does exchanges automatically while the patient sleeps at night. There are three parts to each exchange: filling, dwelling, and draining. Blood tests and clinic visits are conducted regularly to ensure that dialysis is working well for patients. To avoid getting sick, you need to maintain good hygiene.
Recovery & Outlook
Most of the time, recovery after catheter placement is quick. Once patients have been trained and are comfortable with the process, they can resume their normal activities. Peritoneal dialysis is a good way to support the kidneys and is flexible, but strict infection control and regular check-ups are important for long-term success.
