WebApr 10, 2024 · Beractant is used as an intratracheal suspension. It is administered as 100 mg per kg (kilogram), which is 4 mL per kg of birth weight in four divided doses. It should be given within 15 minutes after birth. Repeated doses are administered if the neonate has radiographically confirmed respiratory distress syndrome. WebHere we reported the first detailed biophysical study of phospholipid phase transitions in two animal-derived natural pulmonary surfactant films, Infasurf and Survanta, at the PFC-water interface using constrained drop surfactometry (CDS). The CDS allows in situ Langmuir-Blodgett transfer from the PFC-water interface, thus permitting direct ...
