We prospectively analyzed airway specimens from 24 newborn infants. Inhaled nitric oxide (less than or equal to 20 ppm for 1 to 4 days to 12 infants) did not affect the concentrations of the lipid peroxidation product, the surface activity, or the cytokines (interleukin-l, granulocyte-macrophage colony-stimulating factor, interleukin-l receptor antagonist). Nitrotyrosine was detected after 10 days of life in the two infants requiring prolonged ventilation, suggesting toxicity of endogenous nitric oxide.
