IRDS

Infant respiratory distress syndrome ("RDS", also called "Respiratory distress syndrome of newborn", previously called hyaline membrane disease), is a syndrome caused in premature infants by developmental insufficiency of surfactant production and structural immaturity in the lungs. It can also result from a genetic problem with the production of surfactant associated proteins. RDS affects about 1% of newborn infants and is the leading cause of death in preterm infants . The incidence decreases with advancing gestational age (length of pregnancy), from about 50% in babies born at 26-28 weeks, to about 25 t 30-31 weeks. The syndrome is more frequent in infants of diabetic mothers and in the second born of premature twins.

This occurs particularly in premature infants. This is due to lack of Surfactant so that the alveoli collapse.There is ground-glass appearance of lungs on chest X-rays due to widespread alveolar collapse.
