[Effect of the level and extent of a brain stem lesion on central hemodynamics in patients with an arterial aneurysm in the acute stage of a subarachnoid hemorrhage]. / Vliianie urovnia i stepeni porazheniia stvola golovnogo mozga na tsentral'nuiu gemodinamiku u bol'nykh s arterial'noi anevrizmoi v ostroi stadii subarakhnoidal'nogo krovoizliianiia.

Using the dye-dilution method (indigo carmine), the authors studied the central hemodynamics in 46 people, including 36 patients with arterial aneurysms in the acute period of subarachnoidal hemorrhage and 10 healthy subjects (a control group). Hyperkinetic, hypokinetic and normokinetic types of the central hemodynamics were specified. The hyperkinetic type was characteristic of patients in a satisfactory state and with injuries at the hypothalamo-diencephalic level. The hypokinetic type is characteristic of grave and very grave patients with injuries at the mesencephalodienchephalic and mesencephalo-bulbar levels and with severe damage to the brain stem.

Central hemodynamics was studied in 75 persons; 10 were healthy, 65 had abnormal tortuousness, stenosis, and thrombosis of the internal carotid arteries in the late post-stroke period. Twenty-one patients suffered from arterial hypertension. An increase in the cardiac output was revealed, which was associated with centripetal effects and was compensatory in character.

The main values of central hemodynamics were studied in 20 patients in the acute period of injury with severe contusion of the brain and compression of intracranial hematoma. Three main types of circulatory reactions to the injury were revealed according to the values of the minute circulation volume. The hyperdynamic type of reaction was characterized by a rise of the main values of central hemodynamics; in the hypodynamic type of the circulatory reaction the cardiac output and the volume of circulating red cells were considerably reduced while the peripheral resistance was increased. The normodynamic type was characterized by essentially unchanged main values of central hemodynamics except for a reduced cardiac output and was interpreted as an inadequate reaction of circulation to the injury.

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.
