"Hemorrhage in the newborn" has long been recognized as merely a result of vitamin K deficiency. However, it is also recognized that fibrinolysis, especially the correlation between the plasminogen-activator and plasmin-inhibitors, play an important role in this disease during the neonatal period. With this in mind, we compared thromboelastograms (TEG) from samples with and without urokinase (plasminogen-activator). ⋯ This is especially true in the case of lung hemorrhage since the activator arises from a severe pathological state in the lungs and in addition because this is complicated by the lowering of plasmin-inhibitor. These results indicate that the low level of plasmin-inhibitors work synergistically with the high value of activator. The low level of antithrombin III could be the reason for coagulation disorders such as disseminated intravascular coagulation, (DIC).
