    Abstract:
    The changes of the P50, 2,3-DPG and sodium as well as potassium of red blood cells in perioperative period were studied in 12 patients who underwent hemodilutional autotransfusion (HAT). P50 and 2, 3-DPG did not show remarkable changes before the third day after operation, but increased significantly on 5th and 7th day. There was a positive correlation between P50 and 2,3-DPG. Potassium of red blood cell increased significantly except on the first day. But sodium of red blood cell showed no remarkable change. In conclusion, our data demonstrate that the tissue oxygen supply from the red blood cell is maintained, because P50 did not decrease. Sodium in the red blood cell does not show remarkable changes, and therefore the membrane function of the red blood cell should be kept intact.
