Peritoneal Dialysis is a therapy that typically is managed by patients at home. The therapy works by cleaning the blood of toxins and removing extra fluids through one of the body’s own membranes, the peritoneal membrane. While many dialysis patients in the India go to a dialysis center, PD offers more flexibility by allowing patients to dialyze at home, at work or on vacation.
To perform treatments, PD uses the thin membrane, called the peritoneum, which lines the abdomen. During treatments, a cleansing fluid called dialysate is put into the patient's abdomen through a small, flexible tube called a PD catheter.
The dialysate pulls the waste and extra fluid from the patient's blood into the peritoneal cavity and stays in the abdomen for a specified amount of time. Once the dialysate is drained, the wastes and fluids are also drained, and fresh dialysate is replaced to clean the blood. This filling and draining process is called an exchange because the dialysate that has been in the abdomen is being exchanged for new, fresh dialysate.
There are two methods to infuse and drain (exchange) PD solutions: Continuous ambulatory peritoneal dialysis (CAPD), in which patients manually exchange PD fluids using a solution bag and tubing connected to the catheter several times a day; and automated peritoneal dialysis (APD), in which solution is infused and drained automatically by a cycler machine, typically while the patient sleeps.
