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.^[1] 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.
