Abstract
The article discusses the results of study of central hemodynamics in patients with acquired aortic valvular diseases who were operated on under conditions of hypothermia without perfusion. The minute circulation volume reduced at a temperature of 26.8 degrees C to 63% of the initial level. The stroke volume did not change practically. The changes of the values of central hemodynamics in the stages of hypothermia (active and passive cooling) were irregular in character. No essential inhibiting effect of hypothermia on the cardiovascular activity was noted.
