Dialysis

Description

Dialysis is a technique in which substances move from the blood through a semipermeable membrane and into a dialysis solution (dialysate). It is used to correct fluid and electrolyte imbalances and remove waste products in renal failure. It can also be used to treat drug overdoses.

The two methods of dialysis are peritoneal dialysis (PD) and hemodialysis (HD) (Table 93).

■ In PD the peritoneal membrane acts as the semipermeable membrane.

■ In HD an artificial membrane (usually made of cellulose-based or synthetic materials) is used as the semipermeable membrane and is in contact with the patient’s blood.
