[Bronchopulmonary dysplasia: definitions and classifications]

Abstract

Bronchopulmonary dysplasia is the most common sequelae related to very low birth weight infants, mostly with those of extremely low birth weight. Even with advances in prevention and treatment of respiratory distress syndrome associated with prematurity, there is still no decrease in the incidence in this population, although a change in its clinical expression and severity has been observed. There are, however, differences in its frequency between health centres, probably due to a non-homogeneously used clinical definition. In this article, the Committee of Standards of the Spanish Society of Neonatology wishes to review the current diagnosis criteria of bronchopulmonary dysplasia to reduce, as much as possible, these inter-centre differences.
