The natural membrane of the abdominal cavity is used as a filter. The peritoneal catheter, also called “tenckhoff” catheter, is a soft tube that is surgically inserted into the cavity. The catheter serves as a permanent access and the dialysis solution is attached to it.
The solution runs into the cavity and the bag is then removed from the catheter until the next dialysis. Intensive training is given to ensure that the procedure of peritoneal dialysis is understood and can be done by the patient. Particular care is given to the sterility of the procedure.
The dialysis mixture used is a sterile solution with glucose (Sugar) content. The glucose causes fluid to be drawn from the blood stream to the dialysate in the peritoneal cavity. Osmosis and diffusion take place between the liquids. The dialysate is changed every 4-6 hours.
Peritoneal dialysis is done every day by the patient. The most common types of peritoneal dialysis are Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD)
Advantages of Peritoneal Dialysis
- No Needles
- More Freedom
- More flexibility
- Own Schedule
- Controlled Blood Pressure
Disadvantages of Peritoneal Dialysis
- 4X Changer per 24h
- No Days can be skipped
- Permanent catheter
- Slight chance of infection (Peritonitis)
- Slight chance of weight gain
- No Swimming
Variations of Peritoneal Dialysis
Is done daily by the patient at home. The dialysis must be changed 4 times per day (Every 4- 6 Hours).
Morning, afternoon and before bed. CAPD gives you constant dialysis 24 hours a day, 7 days a week and this ensures continuous dialysate exchange in the abdominal cavity.
Is done at home with the help of a machine. This type of dialysis is done during the night while the patient is asleep. A unique set is connected to the “cycle” machine. The machine does 4-6 exchanges per session. The machine is quiet and won’t disturb you rest.
Patients using peritoneal dialysis lead a normal life. They can keep on working, travel and continue with their normal activities. Special arrangements are made by North West Dialysis Centre for the delivery of the dialysate at your home.
