Increased Tolerance to Posthaemorrhagic Shock in Dogs treated with Reserpine

Naturevolume 214pages202203 (1967) | Download Citation



THE mechanism governing the development and consequences of posthaemorrhagic circulatory collapse has been tentatively related to the activation of the sympathetico-adrenal system. During an early reversible stage after haemorrhage, this activation leads to compensatory readjustments; in a later irreversible stage the persisting sympathetico-adrenal activity brings about vascular and tissue lesions, especially at sites exposed to prolonged vasoconstriction. At this stage the situation cannot be remedied by restoring the blood volume.
