During hypothermic anaesthesia for cardiovascular surgery, it has been noted that a hypertensive phase immediately succeeds the period of circulatory occlusion. The mechanism of the hypertension was investigated in six patients by determining the adrenalin and noradrenalin plasma levels before and after occlusion. A close relationship was observed between the sudden increase in systemic blood pressure and the abrupt rise in plasma catechol amines.
