Dialysis

Hemodialysis

In hemodialysis, blood is taken through a catheter inserted in the external jugular vein. The blood is passed through the hemodialyzer (an artificial kidney) which filters waste products from the cat's blood. The filtered blood is then returned to the cat through a second lumen in the same catheter. The blood is circulated several times during one treatment session. The catheter remains in place for as many sessions as are necessary.

For each dialysis session, the patient is evaluated, the catheter is prepared, the patient is dialyzed, the patient is evaluated again and the catheter is cleaned and treated with heparin. A hemodialysis session lasts from three to five hours.

Hemodialysis is mainly used to treat cats in acute renal failure while their kidneys are recovering their function. Chronic renal failure patients can benefit from a course of hemodialysis prior to or after a kidney transplant procedure.

Few veterinary facilities are able and equipped to perform this procedure at this time.

General Information

Kidney Dialysis, Is It For Your Pet? By Wendy C. Brooks, DVM, DipABVP VeterinaryPartner.com

Peritoneal dialysis

Peritoneal dialysis uses the peritoneum (the thin lining of the abdominal cavity) as the filter for separating waste products from larger substances. The dialysis is performed with a special tube that a veterinarian uses to fill the cat's abdominal cavity with dialysis fluid. Waste products in the body suffuse into the fluid. The doctor then removes the fluid from the abdominal cavity and discards it, repeating the procedure until the level of waste products is adequately reduced.

Peritoneal dialysis is easy to perform in cats and is not painful for the patient. The need for constant monitoring and professional application usually limits the use of peritoneal dialysis to the treatment of reversible acute renal failures where the dialysis performs the waste removal function of the kidneys while the kidneys themselves are recovering.
