Q.What is
peritoneal dialysis ?
A. Peritoneal dialysis is a way to remove waste products
from your blood when your kidneys can’t adequately do the job any longer. This
procedure filters the blood in a different way than does the more common
blood-filtering procedure called hemodialysis.
During peritoneal dialysis, a cleansing fluid flows
through a tube(catheter) into the part of your abdomen. The lining of you
abdomen (peritoneum) acts as a filter and removes waste products from your
blood. After a set period of time, the fluid with the filtered waste products
flows out of your abdomen and is discarded.
Q.How is
peritoneal dialysis done ?
A. You’ll need an operation to insert the catheter that
carries the dialysate in and out of your
abdomen. The insertion might be done under local or general anesthesia. The
tube is inserted near your belly button.
During peritoneal dialysis :
1. The dialysate flows into your
abdomen and stayes there for a prescribed period of time(dwell time)- usually
four to six hours.
2. Dextrose in the dialysate
helps filter waste , chemicals and extra fluid in your blood from tiny blood
vessels in the lining of your abdominal cavity.
3. When the dwell time is over,
the solution- along with waste products drawn from your blood- drains into a
sterile collection bag.
The process of
filling and then draining your abdomen is called an exchange. Different methods
of peritoneal dialysis have different schedules of exchange. The two main
schedules are :
1. Continuous Ambulatory
Peritoneal Dialysis (CAPD)
2. Automated Peritoneal Dialysis
(APD)
Q.When is peritoneal dialysis a better option for you?
A. 1. Can’t tolerate the rapid changes of fluid balance associated with hemodialysis.
2. Want to minimize the disruption of your daily activities, gives greater lifestyle flexibility and independence.
3. Preserves residual renal function.
Q. What are the complications of peritoneal dialysis?
A. 1. Infections.
2. Weight Gain.
3. Hernia.
