Peculiarities of the Cardiovascular System State in Newborns with Extremely Low Body Mass
An analysis of the children with extremely low body mass (ELBM) risk factors is presented. It is demonstrated, that the endured prenatal and postnatal asphyxia, a type of delivery influence the adaptation mechanisms of a child with ELBM in 37,7% of premature children with ELBM a durative functioning of the hemodynamically significant open arterial duct and open oval window is encountered in them, there is postponed dynamics of a pulmonary blood flow mature type forming with the pulmonary hypertension signs. A hemodynamically significant functioning arterial duct is associated with a high rate of the CNS critical hypoxically-hemorrhagic lesion development (the intraventricular hemorrhages, periventricular leukomalation). The premature children preserve a probability of the arterial duct repeated opening by the 3d week, which can lead to a state aggravation.
