Medical blood changers do not treat aplastic anemia. Aplastic anemia patients often have severe anemia, if the hemoglobin is lower than 60g/L, the patient’s clinical symptoms are obvious, you can enter the concentrated red blood cells, which means blood transfusion treatment, so aplastic anemia patients if the blood red blood cells are significantly reduced, clinical symptoms are obvious, you need to transfusion treatment, do not need to change the blood treatment. Medical blood changers are usually used to treat hemolysis in newborns and other hemolytic diseases or uremic syndrome, etc.. Blood exchange therapy is used to treat the disease by feeding a large amount of fresh and normal plasma into the patient’s body and replacing the abnormal plasma in the patient’s body. Blood exchange is not effective for patients with aplastic anemia. Pharmacological treatment of aplastic anemia mainly includes immunosuppressants such as anti-lymphocyte globulin (ALG) or anti-thymocyte globulin (ATG), cyclosporine A, cyclophosphamide, methylprednisolone, etc., androgens such as testosterone propionate, and hematopoietic growth factors such as granulocyte-monoclonal colony-stimulating factor (GM-CSF) to stimulate hematopoiesis in the bone marrow. Patients with aplastic anemia should follow the doctor’s instructions to actively cooperate with the doctor’s treatment, do not self-medication, so as not to delay the condition.
