Indicators of the dynamics of perinatal hypoxia in newborns

A comprehensive study of clinical and neurological changes in newborns in the relationship between the nature and duration of perinatal hypoxia (PH) was carried out. To assess the state of clinical and neurological changes, 52 newborns who underwent perinatal hypoxia were examined. The anamnesis of mothers who underwent combined perinatal hypoxia was significantly worse than in the group of children with acute asphyxia. Anemia, acute respiratory viral infection (ARVI), preeclampsia, fetoplacental insufficiency (FPI), the duration of the anhydrous interval, pathological childbirth served as predisposing factors contributing to the development of perinatal hypoxia. For an objective quantitative assessment of the dynamics of the neurological status of newborns, the “Scoring of the severity of perinatal encephalopathy”, developed at the Research Institute of Pediatrics of the Russian Academy of Medical Sciences by A.A. Stepanov (1998), was used. It is based on an integrated assessment of motor activity, innate reflexes and behavioral reactions of newborns, taking into account the quantitative characteristics of each newborn. The data obtained indicate that the duration of hypoxia, the state of health, the course of pregnancy and childbirth in the mother determine the severity of perinatal brain damage and affect the severity of clinical and neurological patterns. Combined perinatal hypoxia leads to deeper brain disorders and contributes to the formation of two or more syndromes in one child.
