Body Weight Growth After Birth and Bronchopulmonary Dysplasia

Bronchopulmonary dysplasia (BPD) is one of the most common, complex, and severe diseases in preterm infants. BPD was first described as chronic pulmonary disease in survivors of severe respiratory distress syndrome (RDS) in 1967, which was also called as the "old" BPD. In recent years, the definition for BPD has developed a lot. The National Institute of Child Health and Human Development (NICHD) workshop in 2018 assessed BPD at 36 post-menstrual age (PMA) along with radiographic confirmation and used a severity grading of I-III. Although with effective surfactant supplement and oxygen support, BPD brings a great challenge to neonatologists.
