The main advantage of PD is that it can be done at home. The medicine bags can be delivered directly to your home. Patients on PD are therefore very independent and need to visit the hospital once a month for a check-up, unlike HD where patients have to visit 3 time a week. Since the dialysis is continuous, there are fewer dietary and fluid restrictions than on haemodialysis. Patients can travel to out of town and can do dialysis wherever they go.
Peritoneal Dialysis is a method of cleaning the blood without the blood leaving the body. Clean fluid (dialysate) is run through a tube into the abdominal cavity. A thin membrane called the peritoneum lines the inside of the abdomen. The peritoneum has tiny holes (or pores) through which the waste products can pass from the bloodstream into the dialysate. When the dialysate is drained out again through the tube, the waste products are removed from the body at the same time. There are two types of peritoneal dialysis CAPD (Continuous Ambulatory Peritoneal Dialysis) and APD (Automated Peritoneal Dialysis). CAPD is done manually, while a machine is used for APD. In both types, dialysate fluid comes in High grade Medical plastic bags which are stored at the patient’s home. The fluid is drained into the abdomen, and after staying there for a period of time, it is drained out into an empty bag. In CAPD, four bags are used during a 24-hour period three during the day and one at night. It takes 5 to 10 minutes for the fluid to run in and 20 to 30 minutes for the fluid to drain out. The bag changes can be done at home or at work. There is complete freedom to carry out daily living routines between bag changes.
