Anemia and thrombocytopenia are frequent in this diverse group of patients, who receive treatments until the end of life, the transfusion of blood components, such as red blood cells or platelets, being a necessary intervention for the relief of symptoms and improvements in condition. clinical. However, in terminally ill patients, symptoms are multifactorial in origin and hematological values do not necessarily become a criterion for transfusing, however, the scientific evidence supporting that transfusions significantly improve the symptoms of palliative patients has not yet is conclusive. Although the literature defines some indications for transfusing difficulties, they begin in the context of the selection of the type of transfusion, the amount of the transfusion, and the end of life. In the scientific literature there are different reports that list the last units of blood products administered, prior to the death of the patient; however, little is found in relation to uniform criteria that support the decision at the end of life and the risk benefit ratio is not clear.
