title: [Bronchopulmonary dysplasia].
abstract: Bronchopulmonary dysplasia (BPD), a respiratory disorder first described in prematurely born infants with respiratory distress syndrome (RDS) treated with mechanical ventilation and oxygen supplementation, is the most common cause of chronic lung disease in infants. It is defined as the need for increased inspired oxygen at 28 days of age, and is observed with the highest frequency following premature delivery of very low birth weight infants. Indeed, an incidence of 48% has been recently reported in a population with a mean gestational age of 27 weeks. The etiology of BPD is multifactorial including lung immaturity, respiratory distress, oxygen therapy, and mechanical ventilation. Based on the current understanding of the pathogenesis of the disease, several therapeutical strategies are used. One of them is focused on the prevention of BPD by correcting surfactant deficiency in premature infants with RDS using exogenous surfactant, and also by improving the techniques of mechanical ventilation used for the management of RDS. Another approach which is being developed is focused on the factors involved in the processes of repair of the injured immature lung. These factors include the use of inhibitors of the inflammatory cascade, antioxidants, and inhibitors of fibrosis.
