When anemia is caused by acute heavy bleeding and severe anemia requires blood transfusion therapy.
Anemia is a decrease in the volume of red blood cells in the peripheral blood due to the body’s inability to make enough hemoglobin. Whether or not anemia requires a blood transfusion needs to be decided on a case-by-case basis. If there is acute short-term heavy bleeding that triggers shock, then blood transfusion is needed as soon as possible to replace the lost blood volume.
Secondly, the severity of anemia should be assessed. Severe anemia requires blood transfusion, and routine blood test results suggesting hemoglobin concentration <60g/L and hematocrit <0.2 are all indications for blood transfusion. For people with chronic anemia, the most important thing is to find the cause of the anemia under the guidance of the doctor and treat the anemia from the root.
Whether anemia requires blood transfusion should be decided by a professional doctor according to the individual's situation.
