Autologous blood transfusion is a kind of autologous blood that is returned to patients after scientific treatment. Before the operation, the doctor will draw a certain amount of blood from the patient and treat it by certain methods, such as removing red blood cells or white blood cells, so as to make it conform to the patient's use specifications. During the operation, if there is a lot of blood loss and blood transfusion is needed, the treated autologous blood can be returned to the patient to avoid blood transfusion reaction caused by blood group incompatibility, infection and other problems.

The advantages of autologous blood transfusion are very obvious. First of all, because autologous blood is the patient's own blood, there will be no immune rejection and infection. Secondly, autologous blood transfusion greatly reduces the risk of transfusion reaction and the incidence of postoperative complications. Finally, autologous blood transfusion can significantly reduce the probability of postoperative anemia, which is very beneficial to the rehabilitation of patients.

Although autotransfusion has many advantages, not all patients can accept this method. First of all, you need to be able to predict a lot of blood loss in order to draw blood in advance; Secondly, the extracted blood needs to be treated before blood transfusion, which requires higher equipment and technology in the hospital; Finally, patients with some diseases, such as leukemia or hemophilia, are not suitable for autologous blood transfusion. Therefore, in clinic, doctors will judge whether it is suitable for patients to carry out autologous blood transfusion according to specific conditions.
