ABSTRACT

In this article, we reviewed the physiologic aspects of adaptation to acute chronic anemia to better understand the need to transfuse a patient, making rational use of this resource to lead us to avoid abuse of transfusions, which always entail a risk. We attempted to establish a threshold number of whether the patient hemoglobin showed be transfused; according to diverse studies, this number can fluctuate between 6 and 10 g/dL, depending on patient type, age, and cardiovascular and clinical condition. Different types of progress exist with regard to erythrocyte transfusion related with leukoreduction, decrease of risk of transmittable diseases, and management of preoperatory isovolemic hemodilution, among others. Analysis of this progress and the physiopathology of anemia lead us to the conclusion that hemoglobin value is null in hypovolemia and that in chronic anemia it is only complementary to patient diagnosis and clinical evaluation, which should determine therapeutic decision-making.
