Surfactant status and respiratory outcome in premature infants receiving late surfactant treatment.


ABSTRACT: BACKGROUND:Many premature infants with respiratory failure are deficient in surfactant, but the relationship to occurrence of bronchopulmonary dysplasia (BPD) is uncertain. METHODS:Tracheal aspirates were collected from 209 treated and control infants enrolled at 7-14 days in the Trial of Late Surfactant. The content of phospholipid, surfactant protein B, and total protein were determined in large aggregate (active) surfactant. RESULTS:At 24?h, surfactant treatment transiently increased surfactant protein B content (70%, p?
