[Effects of hyperbaric oxygenation on free radical oxidation and antioxidant system of blood in the newborn who had acute hypoxia at birth].

Hyperbaric oxygenation (HBO) was added to the complex of intensive care for 14 full-term newborns born asphyxiated and with cerebral circulation disorders of the I-II degree. Study of the antioxidant enzymatic system and free-radical oxidation by chemiluminescence showed no changes in superoxide dismutase and catalase and a 1.6-2 times increase in the activity of glutathione peroxidase, on the one hand, and an appreciable decrease of free radical processes, on the other. This permitted a conclusion about the absence of toxic effects during HBO and on its membrane-stabilizing action.
