[THE ROLE OF SEXUAL DYMORPHISM AND THE STATE OF THE ARTERIAL DUCT IN THE FORMATION OF OXIDATIVE STRESS DISEASES IN PRETERM INFANTS].

Oxidative stress is a state of imbalance between the production of reactive oxygen species and their inactivation by the body's antioxidant systems. Premature babies are susceptible to oxidative stress due to an imperfect antioxidant system. Oxygen resuscitation, respiratory therapy, surfactant use, and other intensive nursing techniques increase the production of reactive oxygen species and increase oxidative stress.

[PREDICTOIN OF THE COURSE OF BRONCHOPULMONARY DYSPLASIA IN PRETERM CHILDREN UP TO 3 YEARS OF AGE].

The introduction of modern technologies for nursing premature babies has led to an improvement in the survival of premature infants and, at the same time, to an increase in the incidence of bronchopulmonary dysplasia (BPD). Тhe aim of work - to determine the characteristics of the course of BPD in premature infants and to provide methods for predicting the course of BPD up to 3 years of age. Using Spearman's nonparametric correlation analysis, a direct correlation between the severity of BPD at 6 months of age and the surgical closure of the hemodynamically significant patent ductus arteriosus (PDA) in the neonatal period (k=0.
