Can anemia be improved through blood transfusion?

Anemia is a very common disease in daily life. It has a great impact on human health and can cause a series of diseases. This condition is more common in female friends. So people are eager to find scientific and effective ways to replenish blood. Blood transfusion is indeed a way to improve anemia, but it cannot be used as an effective treatment, so friends with anemia need to pay special attention.

1. Blood transfusion can improve anemia

Blood transfusion is a measure in the supportive treatment of anemia, but blood transfusion can only be used as symptomatic treatment and cannot replace the special treatment of anemia, nor can it be used as an effective treatment for anemia. Blood transfusions only provide a temporary cure. Generally, patients do not have obvious symptoms of anemia, and blood transfusion is not considered when their hemoglobin is above 6 g/dL. Blood transfusion for anemic patients is usually considered when anti-anemia drug treatment is ineffective, or when the anemia is more severe or the anemic patient must undergo surgery due to other diseases within a short period of time, in order to save his life and as a preoperative preparation.

2. Hypertransfusion reaction

Excessive blood transfusion may suppress the hematopoietic function of the bone marrow. Blood transfusion can also cause certain side effects, even fatal risks. for example:

1. Fever and allergic reactions;

2. Hemolytic reaction caused by blood type incompatibility;

3. Large amounts of blood transfusion or blood transfusion at too fast a speed can cause excessive heart load and lead to acute heart failure.

Blood transfusions carry the risk of transmitting viral hepatitis. At present, my country only conducts hepatitis B surface antigen tests on blood donors, and hepatitis C antibody tests can be conducted in some areas. Hepatitis D and hepatitis E cannot be detected yet. Therefore, there may be hepatitis virus carriers among blood donors, and the hepatitis virus may be spread through blood transfusion.

Therefore, the indications for blood transfusion must be strictly followed. In the event of acute massive blood loss, blood transfusion is extremely important for restoring normal blood volume and needs to be replenished in a timely manner. Blood transfusion is often used to treat aplastic anemia, and the effect is quite obvious. Blood transfusion is generally not used to treat iron deficiency anemia, megaloblastic anemia and certain hemolytic anemias. Especially for some hemolytic anemias, such as autoimmune hemolytic anemia or paroxysmal nocturnal hemoglobinuria, blood transfusion not only fails to alleviate the condition, but may also aggravate the hemolytic reaction, so you should be vigilant!
