Hemoperfusion is a treatment technique in which large volumes of the patient's blood are passed over an adsorbent substance in order to remove toxic substances from the blood. Adsorption is a process in which molecules or particles of one substance...
are attracted to the surface of a solid material and held there. These solid materials are called sorbents. Hemoperfusion is sometimes described as an extracorporeal form of treatment because the blood is pumped through a device outside the patient's body.
The sorbents most commonly used in hemoperfusion are resins and various forms of activated carbon or charcoal. Resin sorbents are presently used in Europe but not in the United States; since 1999, all hemoperfusion systems manufactured in the United States use cartridges or columns containing carbon sorbents. A newer type of cartridge containing an adsorbent polymer has been undergoing clinical tests in the United States since the summer of 2002.
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.
In 2000, the estimated number of hospital admissions among adults aged 18 or older with urinary incontinence listed as a diagnosis was of 47,802 hospital stays (1,332 men; 46,470 women).
