In medicine, dialysis is a type of renal replacement therapy which is used to provide an artificial replacement for lost kidney function due to renal failure. It is a life support treatment and does not treat any kidney diseases. Dialysis may be used for very sick patients who have suddenly lost their kidney function (acute renal failure) or for quite stable patients who have permanently lost their kidney function (end stage renal failure). When healthy, the kidneys remove waste products (for example potassium, acid and urea) from the blood and also remove excess fluid in the form of urine. Dialysis treatments have to duplicate both of these functions as dialysis (waste removal) and ultrafiltration (fluid removal).
The
Principle of Dialysis
Dialysis works on the principle of the
diffusion of solutes
along a concentration gradient across a
semipermeable membrane.
In all types of dialysis, blood passes on one side of a semipermeable
membrane, and a dialysis fluid is passed on the other side. By altering the
composition of the dialysis fluid, the concentrations of undesired solutes (chiefly
potassium and
urea) in the fluid
are low, but the desired solutes (for example
sodium) are at their
natural concentration found in healthy blood.
