ABSTRACT
OBJECTIVE: This retrospective analysis assessed the relationship between medical treatment (postnatal steroids, surfactant) received neonatally and outcomes at 3 and 8 years using a longitudinal sample of children with bronchopulmonary dysplasia (BPD). STUDY DESIGN: Four groups were formed retrospectively based on the type of neonatal medical treatment received: no drug intervention (n=37), surfactant only (n=29), postnatal steroids only (n=13) and combined surfactant and postnatal steroids (n=16). Groups were compared on neurological and medical outcomes. RESULT: Combined postnatal steroids and surfactant treatment was associated with more days on supplemental oxygen than no intervention or surfactant only. Surfactant replacement therapy alone was not associated with adverse consequences; however, postnatal steroid exposure appeared to be related. CONCLUSION: Although retrospective analyses make statements about causation impossible, the differential relationships of therapies with cognitive outcomes argues for careful monitoring of therapeutic agents with very low birth weight infants.
