[State of central hemodynamics in cerebral arterial aneurysms in the acute period of subarachnoid hemorrhage].

Central hemodynamics was studied by the method of dye (indigo carmine) dilution in 44 persons, 34 of whom had saccular aneurysms of the cerebral arteries in the acute period of subarachnoid hemorrhage and 10 formed the control group. Central hemodynamics changed depending on the condition of the patient. In a satisfactory and moderately severe condition, the cardiac output (minute circulation, volume, stroke volume cardiac index) was increased. In a severe and extremely severe conditions, the values of the cardiac output and the volumes of circulating blood, plasma, and red cells were sharply reduced, while peripheral resistance was increased.
