What is out -of -the -case therapy?
The term "extracorporeal therapy" is used to describe any medical treatment that takes place outside the body, although not necessarily without any form of invasive procedure. Most extracorporeal treatments are related to the circulatory system, involving the removal and treatment of blood and then the subsequent return on this blood to the body. This term is also sometimes used, albeit incorrectly, to describe external treatment that causes effect in the body.
Circulation procedures classified as extracorporeal therapies include: plasmapheresis, hemodialysis and assisted blood circulation. All these procedures include the use of machines to draw blood outside the body, processing and then returning it to the body and being used to treat different conditions. Plasmapheresis includes plasma filtration from Blood, and is usually used for autoimmune conditions. Depending on the condition and the patient, the plasma may be treated and returned or replaced. Hemodialysis is used to filter blood during kidney failure, replacing the kidneys and filtering harmful substances in the blood.
People also describe lithotripse of extracorporeal shock waves, a procedure used to treat kidney stones as extracorporeal therapy. This classification is not technically correct, because although the machine used to generate shock waves is outside the body, it acts on the kidney stones inside the body and breaks them so that they can be browsed through the urinary tract. Shock wave therapy is also used experimentally in the treatment of some other health conditions and in all cases the shock waves are designed to penetrate the body, so that therapy should not actually be considered.
Extracorporeal therapy is also used in the treatment of some tumors, usually bone tumors. If extracorporeal therapy can help the patient, the affected bone is removed, subjected to a large dose of radiation and then replaced, in an effort to save the limb. Because radiation is targeted, it is more effective and higher dose can be used BEz concerns about the patient damage because the bone is outside the body.
