Background: Mortality from hemorrhage in renal failure and liver, chronic units critical is 40% and the deleterious effects related to transfusion are high, the decision to transfuse should be selected, methods of interpretation of coagulation go global test methods like tromboelastograma, however what is most effective for guiding a better decision making? Method: A study was conducted in patients with bleeding in the Naval General Hospital of high specialty of the city of Mexico with diagnostic Insufiencia hepatic or Renal chronic who were randomized into two arms, one global test of coagulation and the other the tromboelastograma, for both hemoglobin goal was more than 7 grams/dl and venous saturation greater than 65%, during resuscitation was assessed the occurrence of lung injury and circulatory overload transfusion as well as presence of thrombosis-associated. Results: 31 patients who met the screening criteria were included where TEG® when compared with global testing showed reduction of transfusion in the treatment of hemorrhage (1. 71± 1.2 vs 3.41 ± 3.04, P: 0.04) without complications (p < 0.05) Conclusion: TEG® is effective to reduce the use of procedures and thereby reduce complications and mortality.
