Normal results include satisfactory clearance of the toxic substance or waste products from the patient's blood. The success of hemoperfusion depends in part, however, on the nature of the drug or poison to be cleared from the blood. Some drugs, such...
as the tricyclic antidepressants, enter the tissues of the patient's body as well as the bloodstream. As a result, even though hemoperfusion may remove as much as 80% of the drug found in the blood plasma, that may be only a small fraction of the total amount of the drug in the patient's body.

Other Information
Hemoperfusion (British English: haemoperfusion) is a medical process used to remove toxic substances from a patients blood. The technique involves passing large volumes of blood over an adsorbent substance. The adsorbent substance most commonly used in hemoperfusion are resins and activated carbon. Hemoperfusion is an extracorporeal form of treatment because the blood is pumped through a device outside the patient's body.
Its major uses include removing drugs or poisons from the blood in emergency situations, removing waste products from the blood in patients with renal failure, and as a supportive treatment for patients before and after liver transplantation.
