Changes in the Incidence of Bronchopulmonary Dysplasia among Preterm Infants in a Single Center over 10 Years

ABSTRACT

Purpose@#Bronchopulmonary dysplasia (BPD) is one of the most fatal respiratory morbidities in preterm infants, causing adverse respiratory and neurodevelopmental outcomes. Despite advances in neonatal ventilator care, the incidence of BPD has been static or even increased. The purpose of this study was to evaluate the incidence of BPD in a single center over 10 years. @*Methods@#Preterm infants with gestational age (GA) @*Results@#Among 629 infants, 521 infants who survived 28 days or more were enrolled (BPD group, n=252; non-BPD group, n=269). The incidence of BPD was 48.4%, with moderate to severe BPD accounting for 13.9%. In preterm infants with GA ≤25, 26 to 27, and 28 to 29 weeks, the incidences of BPD were 57.5%, 51.5%, and 14.6%, respectively, with moderate to severe BPD accounting for 23.8%, 10.5%, and 3.7%, respectively. The incidence of BPD decreased from 68% in 2009 to 34.3% in 2014. Subsequently, it increased. Surfactant re-dosing and patent ductus arteriosus were more frequent in the BPD group than in the non-BPD group. @*Conclusion@#BPD did not decrease over the previous 10 years despite advances in neonatal care.
