Outline of Final Research Achievements

We measured a change of the brain blood volume at the transfusion therapy in the anemia of prematurity using TRS and reported that an absolutely needed quantity of the cerebral blood volume decreased by transfusion.Clinical manifestations improvement effect with the transfusion was remarkable in a case with much cerebral blood volume before the transfusion.The cerebral blood volume can become the new transfusion adaptation criterion.The cerebral hypovolemia shows that there is vicarious brain increased blood volume for the progression of anemia in the background at transfusion.However, it was unexplained how increase of this cerebral blood volume occurred.We produced the increase of the cerebral blood volume with the progression of anemia by increase of the cerebral arteryal blood volume using a piglet anemia model, and it determined the cerebral venous blood apothecaries measure not to almost change even if anemia progressed.
