ABSTRACT
The clinical, radiologic, and pulmonary function changes that occur with bronchopulmonary dysplasia (BPD) have not been extensively studied through infancy and childhood. Only a relatively few studies have attempted to look at pulmonary function years after suffering from BPD (Table 1). This is probably related to several factors. First, the disorder is relatively young, having been described only about 30 years ago (1,2). Second, the rapidly changing approach to the treatment of the preterm infant with hyaline membrane disease (HMD) has made follow-up studies difficult because the population of surviving infants keeps changing along with therapeutic modalities.
