Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
The collected blood product, which contains red blood cells, platelets and coagulation factors, is reinfused at the end of the surgery. [21] [22] People who are in good health and not anemic may sometimes donate their own blood prior to the surgery (autologous blood donation), which helps to conserve donor units and reduces some of the risks of ...
For religious reasons, Jehovah's Witnesses may choose not to accept any allogeneic transfusions from a volunteer's blood donation but may accept the use of autologous blood salvaged during surgery to restore their blood volume and homeostasis during the course of an operation, although not autologous blood donated beforehand. Each Jehovah's ...
Autologous blood therapy, also known as autologous blood injection or autohemotherapy, comprises certain types of hemotherapy using a person's own blood (auto-+ hemo-+ therapy). There are several kinds, the original belonging only to traditional medicine , alternative medicine , and some newer kind of medicine under investigation.
The free flap is sutured to the defect, while it is monitored to ensure the blood vessels remain patent (i.e. the vessels have good blood flow). The donor site area is closed primarily. Sometimes a Split Thickness Skin graft (STSG) may be performed and placed on top of the defect site and/or the donor site.
Autologous blood cell salvage is a therapeutic approach to recover the blood during cardiac surgery. Today, it is also widely used in many other high risk of surgeries around the world. [ 2 ] Some reports suggest that if autologous blood cell salvage is routinely used in open heart surgeries, the requirements for blood transfusions can be ...
In most cases, the blood is discarded if it is not used instead of being added to the general supply. Blood donation prior to colorectal cancer surgery seemed causative for a worse overall and colorectal cancer specific survival. [4] Autologous blood is not routinely tested for infectious diseases markers such as HIV antibodies. In the United ...
Nearly all exchange transfusions are allogeneic (that is, the new blood or blood products come from another person or persons, via donated blood); autologous exchange transfusion is possible (using autologous blood banking), but there are not many situations in which a need for it arises, as most autologous transfusions involve no exchange.
