Effect of hemorrhage on hepatic blood flow determined by radioactive colloidal chromic phosphate removal.

In a group of IS anesthetized dogs hepatic blood flow measured by the BSP removal technio of Bradley and the radioactive colloidal chromic phosphate disappearance method of Dobson gave comparable results of 3S.7 and 38.3 liil./Kg./niin. respectively. In response to acute hemorrhage of 25 ml./Kg., hepatic blood flow fell from 42.3 to 35.4 ml./Kg. A more severe hemorrhage of"33 ml./Kg. produced a more profound decrease of hepatic blood flow, from 43.4 to 20.S iiil./Kg./min.
