Hemoperfusion
MeSHD006464

Hemoperfusion (British English: haemoperfusion) First introduced in the 1940s, the technique was refined during 1950 to 1970, and then introduced clinically for the treatment of poisoning in the 1970s and 1980s. It is sometimes used in drug overdose possibly in conjunction with other extracorporeal techniques such as hemodialysis(HD), peritoneal dialysis(PD), hemofiltration(HF), and hemodiafiltration(HDF).[1]

Two types of hemoperfusion are commonly used:

1) Charcoal hemoperfusion, which has been used to treat liver (hepatic) failure, various types of poisoning, and certain autoimmune diseases when coated with antigens or antibodies.

2) Certain resins(Polystyrene - XAD series) are frequently more efficient at clearing lipid soluble drugs than charcoal hemoperfusion.

Hemoperfusion is also used in the treatment of specific intoxications, such as valproic acid, theophylline, and meprobamate.

[2][3]

Despite its availability, this technique is only infrequently utilized as a medical process used to remove toxic substances from a patient's blood.[4] Complications of hemoperfusion may include thrombocytopenia, leucopenia, hypoglycemia, and some reduction in clotting factors, with recovery typically occuring in 1-2 days. Risk of bleeding is also higher because of high heparin dose and reduction in platelets and clotting factors.[5]

During hemoperfusion, the blood passes through a column with absorptive properties aiming at removing specific toxic substances from the patient’s blood. It especially targets small- to medium-sized molecules that tend to be more difficult to remove by conventional hemodialysis. The adsorbent substance most commonly used in hemoperfusion are resins and activated carbon.[6] 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 kidney failure, and as a supportive treatment for patients before and after liver transplantation.[7]
