Особенности мозгового кровотока у глубоко недоношенных детей в динамике раннего неонатального периода

The purpose of work: to set options of cerebral blood flow in children with extremely low (ELBW) and very low birth weight (VLBW) in the dynamics of early neonatal adaptation, to identify risk factors of subependymal hemorrhage (SEH), intraventricular hemorrhage (IVH) and their prevention. Results of researches: The study at day 1 showed a reduction of the resistance index (RI) in the basins of cerebral arteries anterior and media (CAA, CAM) and reduced blood flow in the vein of Galen in infants with VLBW and ELBW at birth, which was combined with the development of SEH in 30 children from 39. On the third day we found the increase of blood flows rate in the vein of Galen, especially in children with VLBW, which improved the hemodynamic situation. Conclusions: The detected changes of cerebral blood flow supplement clinical and functional characterization of disadaptation of very preterm infants who implemented by SEH and IVH 1 degree. In our opinion, it is necessary to take into account the degree of fluctuation in blood flow wither decrease of RI in the basins of CAM and CAA and the change of blood flows in the vein of Galen, which are promoting the implementation of SHE and IVH.
