[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.
