Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
Pulmonary surfactant is a surface-active complex of ... alveolar sac stage of lung development. ... of surfactant, commonly seen in premature babies born before ...
Pulmonary surfactant is critical for inflation to occur, as it reduces the surface tension of the alveoli. Preterm birth around 26 weeks frequently results in severe respiratory distress, although with current medical advancements, some babies may survive. Prior to 26 weeks, sufficient pulmonary surfactant is not produced, and the surfaces for ...
Pulmonary surfactant is used as a medication to treat and prevent respiratory distress syndrome in newborn babies. [1] Prevention is generally done in babies born at a gestational age of less than 32 weeks. [1] It is given by the endotracheal tube. [1] Onset of effects is rapid. [2] A number of doses may be needed. [2]

Surfactant therapy is the medical administration of pulmonary surfactant that is derived from outside of the body. Pulmonary surfactant is a soap-like chemical synthesized by type II alveolar pneumocytes and is of various lipids (80% phospholipids, 5-10% cholesterol, and ∼10% surfactant-associated proteins).
