Understand how bronchopulmonary dysplasia (BPD) and antenatal and postnatal factors influence diaphragmatic functional effectiveness in very preterm infants.
Data on static compliance of the chest wall (Ccw) in preterm infants are scarce. We characterized the static compliance of the lung and Ccw to determine their relative contribution to static compliance of the respiratory system in very preterm infants at 36 wk postmenstrual age. We also aimed to investigate how these compliances were influenced by the presence of bronchopulmonary dysplasia and impacted breathing variables.
Surfactant is a well-established therapy for preterm neonates affected by respiratory distress syndrome (RDS). The goals of different methods of surfactant administration are to reduce the duration of mechanical ventilation and the severity of bronchopulmonary dysplasia (BPD); however, the optimal administration method remains unknown.
Since the first description of bronchopulmonary dysplasia (BPD), multiple definitions to diagnose BPD and its grading have been published. Several studies have compared the predictive performance of these definitions for long-term outcomes. The objective was to identify the BPD definition with the optimal predictive performance for long-term respiratory and neurological outcomes in preterm infants.
Lung inflammation and impaired alveolarization precede bronchopulmonary dysplasia (BPD). Glucocorticoids are anti-inflammatory and reduce ventilator requirements in preterm infants. However, high-dose glucocorticoids inhibit alveolarization. The effect of glucocorticoids on lung function and structure in preterm newborns exposed to antenatal inflammation is unknown. We hypothesise that postnatal low-dose dexamethasone reduces ventilator requirements, prevents inflammation and BPD-like lung pathology, following antenatal inflammation.
Preterm infants are often vitamin A deficient, and vitamin A has functions that could mitigate the processes that lead to bronchopulmonary dysplasia. Therefore, supplementation of preterm infants with vitamin A to reduce the risk of bronchopulmonary dysplasia makes inherent sense.
