pulmonary surfactant

A lipoprotein secreted by type II alveolar cells that decreases the surface tension of the fluid lining the alveoli, permitting expansion. Synthetic lung surfactant is available for treating patients with respiratory distress syndrome. In obstetrics, fetal production of surfactant can be stimulated by administration of a glucocorticoid 24 to 48 hr before an inevitable preterm birth. Synonym: lung surfactant See: betamethasone; lecithin-sphingomyelin ratioSee also: surfactant
