Neonatal bronchopulmonary dysplasia

Neonatal bronchopulmonary dysplasia is a serious chronic respiratory disease that primarily develops in preterm infants, particularly those born at very low birth weight who require prolonged mechanical ventilation and supplemental oxygen therapy for infant respiratory distress syndrome It is pathophysiologically characterized by arrested lung development, resulting in alveolar simplification, dysmorphic microvasculature, and variable airway inflammation and fibrosis triggered by barotrauma, hyp...

Neonatal bronchopulmonary dysplasia is a serious chronic respiratory disease that primarily develops in preterm infants, particularly those born at very low birth weight who require prolonged mechanical ventilation and supplemental oxygen therapy for infant respiratory distress syndrome Clinically, affected neonates demonstrate persistent oxygen dependency beyond 28 days of life or at 36 weeks postmenstrual age, often accompanied by tachypnea, retractions, wheezing, and impaired gas exchange

It is pathophysiologically characterized by arrested lung development, resulting in alveolar simplification, dysmorphic microvasculature, and variable airway inflammation and fibrosis triggered by barotrauma, hyperoxia, and inflammatory injury to the immature pulmonary parenchyma
