Work is devoted to studying of dynamics of a brain blood-groove in the pool of an average brain artery at operations with cardiopulmonary bypass on patients of advanced and senile age and to identifying the factors influencing its speed parameters. 27 patients at the age of 69,3±4,5 years operated on coronary artery bypass surgery in the conditions of cardiopulmonary bypass were researched. During work it is established that in the studied group, initial indicators of a brain blood-groove were 53,9±0,6% less in comparison with the standard values for this category of patients. Decrease in volume speeds of a cerebral blood-groove (by 46,7±2,5% of rather initial size) was noted at an induction stage in anesthesia and at a stage of connection of the cardiopulmonary bypass and the beginning of hypothermia (by 64,2±3,9% of initial values). During perfusion, at the laminar and pulsing modes of artificial blood circulation, it wasn’t observed a reliable difference in indicators of average linear speed of blood-groove in the pool of an average and brain artery. And the size of cerebral perfusion was influenced authentically by productivity of the cardio-pulmonary bypass.
