Hemoperfusion

Hemoperfusion (pronounced: he-mo-per-fu-sion) is a medical treatment method that involves the removal of specific substances from the blood. It is a type of Extracorporeal therapy where the blood is passed over an adsorbent substance to remove toxic substances. The adsorbent substance may be activated charcoal or specific resins. Hemoperfusion is primarily used in the treatment of drug overdose and poisoning.

Etymology

The term "Hemoperfusion" is derived from the Greek words 'haima' meaning 'blood' and the English word 'perfusion'.

Procedure

During a hemoperfusion procedure, the patient's blood is drawn out of the body and passed through a column containing the adsorbent substance. The toxic substances in the blood bind to the adsorbent, allowing the cleaned blood to be returned to the patient's body.

Uses

Hemoperfusion is commonly used in the treatment of Drug overdose and Poisoning. It is particularly effective for substances that are not easily dialyzable and have a large volume of distribution. Hemoperfusion is also used in some cases of kidney failure, where Hemodialysis or Hemofiltration are not effective.
