DORADO LAMBERT, Aracelis E.  e  REVILLA MONTERO, Jorge. Radicales libres de oxígeno y distress respiratorio agudo. Rev Cubana Pediatr [online]. 2000, vol.72, n.3, pp. 214-219. ISSN 1561-3119.

The formation of free oxygen radicals in the body and the excessive increase of its genesis during exposure to high concentrations of oxygen and in the development of respiratory burst accompanying phagocytosis were reviewed. Also the formation of these radicals in lung during acute respiratory distress was analyzed. Similarly, the present use at the international level of antioxidants and lipoperoxidation blockers to diminish adverse effects of free radicals are addressed in this paper. In spite of these new measures, it was confirmed that the reduction of mortality rate from this disease was due to the improvement of respiratory care particularly the mechanical ventilation.
