Mid‐childhood lung function in a cohort of children with “new bronchopulmonary dysplasia”

Recent advances in perinatal care and neonatal respiratory therapy have led to a new phenotype of bronchopulmonary dysplasia (“new BPD”). The long‐term respiratory outcome of this new form of BPD has yet to be adequately described. Aim of this study was to provide longitudinal data on lung function of an unselected cohort of children born extremely premature (EP) with an extremely low birth weight in the post‐surfactant era.
