Dialysis--Overview



Dialysis is a procedure to remove waste products and excess fluid from the blood

when the kidneys stop working properly.

It often involves diverting blood to a machine to be cleaned.



You need dialysis if your kidneys no longer remove enough wastes and fluid from your

blood to keep you healthy.

This usually happens when you have only 10 to 15 percent of your kidney function left.



Haemodialysis

Haemodialysis is the most common type of dialysis and the one most people are aware of.

In hemodialysis, a dialysis machine and a special filter called an artificial kidney,

or a dialyzer, are used to clean your blood.

During the procedure, a tube is attached to a needle in your arm.

Blood passes along the tube and into an external machine.

  The dialyzer, or filter, has two parts, one for your blood and one for a

washing fluid called dialysate. A thin membrane separates these two parts.

Blood cells, protein and other important things remain in your

blood because they are too big to pass through the membrane.

Smaller waste products in the blood, such as urea,

creatinine, potassium and extra fluid pass through the membrane and are washed away.

Then it is passed back into the arm along another tube.

This is usually carried out 3 days a week, with each session lasting around 4 hours.
