Exchange transfusion
Exchange Transfusion
Exchange transfusion (pronounced: ex-change trans-fu-sion) is a potentially life-saving procedure that is done to counteract the effects of serious jaundice or changes in the blood due to diseases such as sickle cell anemia.
Etymology
The term "exchange transfusion" is derived from the English words "exchange" and "transfusion". The word "exchange" comes from the late Middle English (in the sense ‘mutual giving and receiving’), via Old French from late Latin 'excambium' (from 'excambiare' ‘barter’), based on 'cambire' ‘barter’. "Transfusion" comes from Latin 'transfusio(n-)', from 'transfundere' 'pour from one container to another', from 'trans-' 'across' + 'fundere' 'pour'.
Procedure
During an exchange transfusion, the patient's blood or parts of it are removed and replaced with fresh donor blood or plasma. This procedure is used to replace damaged, abnormal, or diseased blood cells and to increase the volume of blood plasma, which can improve blood flow and oxygen delivery to the body's tissues.
