Abstract

In hemorrhagic hypotension the cortical electrical activity ceases almost entirely and after reinfusion the starting activity fails to return (Kovách and Fonyó, 1960). In the terminal phase of traumatic shock the energy-rich phosphate content of the brain decreases in rats (Kovách et.al. 1952, 1959). A significant hyper-capnia was found in the hypothalamus, in the frontal cortex and in the sagittal sinus blood without marked changes in the thalamus, medulla oblongata and pons (Makláry and Kovách, 1968). Perfusion of the isolated head in ischemic and hemorrhagic shock or 50 ml/min intracarotid blood transfusion in hemorrhagic shock increased markedly the survival time of dogs (Kovách et.al., 1958).
