Clinical and neurophysiological characteristics of neonatal period of children born in early pre-term birth

Abstract

In recent years, there has been a decrease in perinatal and infant mortality rates in the world due to improvements in the quality of medical care for children born in early pre-term birth (32 and less weeks of gestation) (Baranov A.A., Namazova-Baranova L.S., Kurenkov A.L., etc., 2014). Complications of prematurity are the main causes of high infant mortality and morbidity in premature infants, the risk of complications increases with severity of immaturity (Sakharova E.S., 2017). Objective – to study the clinical and neurophysiological features of the neonatal period in children born at the gestational age of 32 weeks or less. Materials and methods: a cohort prospective study of the physical, neurological and neurophysiological status of 85 children born at the age of up to 32 weeks of pregnancy was conducted by a typical sample. Eelectroencephalography (Neuro-Facilities Copyright © 201-2018 Neurosoft) was performed, visual and auditory potentials were determined (Neuro-SPECTR Copyright © 2012-2018 Neurosoft), NSG. Results: on the basis of the obtained data, the dependence of the state of health and severity of neurological pathology on the period of gestation at birth, the severity of hypoxia and the severity of brain damage at birth was confi rmed. It was found out that the main manifestation of the nervous system function in children born at 32 and less weeks of gestation at 38-40 weeks of post-conceptual age is neurophysiological immaturity.
