Peritoneal dialysis occurs inside your body using your body’s peritoneal membrane as a filter. This membrane is a fine layer of tissue that lines your peritoneal (abdominal) cavity, covering organs such as your stomach, liver, spleen and intestines. It has a fine layer of tissues and a rich blood supply.
Peritoneal dialysis uses a soft tube called a catheter. A surgical operation is required to insert the catheter into the peritoneal cavity. The catheter is about 0.5 cm wide and remains in your body until dialysis is no longer needed. One end of the catheter sticks a few centimetres out of your body, so that it can be connected to a bag containing a special fluid. The catheter allows the fluid to enter and leave your peritoneal cavity.
Waste and extra fluid move from your blood into the special fluid, which is then drained from the body. Each time ‘used’ fluid is replaced by fresh fluid, the cycle is called an ‘exchange’. The number of exchanges needed differs from one person to the next.
Four exchanges are usually done each day. Each exchange includes connecting a new bag of fluid, draining out the old fluid and putting the new fluid in. It takes about 30 minutes and can be done almost anywhere, with a few sensible precautions. In between exchanges, the person is free to go about their daily activities.
Exchanges are typically done on waking, at lunch time, at dinner time and prior to going to bed. Some flexibility is available for busy days. CAPD works by gravity. When the drain bag is placed at floor level the fluid drains out. By raising the new dialysate bag above shoulder level, the new dialysate flows into the peritoneal cavity.
