Bronchopulmonary dysplasia - Prolonged high oxygen delivery in premature infants causes
necrotizing bronchiolitis and alveolar septal injury, with inflammation and scarring. This
results in hypoxemia. Today, with the advent of surfactant therapy and high frequency
ventilation and oxygen supplementation, infants with BPD experience much milder injury without
necrotizing bronchiolitis or alveolar septal fibrosis. Instead, there are usually uniformly
dilated acini with thin alveolar septa and little or no interstitial fibrosis. It develops most
commonly in the first 4 weeks after birth.
