[The reactions of the sympathoadrenal system during the correction of acquired mitral defects under perfusion-free hypothermia].
Blood plasma adrenalin and noradrenaline were measured during correction of acquired mitral defect under conditions of hypothermia without perfusion. Superficial ether anesthesia combined with morphine in a dose of up to 1 mg/kg and droperidol in a dose of up to 0.1 mg/kg did not fully block the sympathoadrenal reaction to cooling. An increase of catecholamines was revealed during cooling, the maximal level being observed in the postocclusion period. Disconnection of the heart from circulation caused an expressed activation of the sympathoadrenal system with the predominance of the adrenomedullary component.
