HYALINE MEMBRANE DISEASE ( RESPIRATORY DISTRESS SYNDROME )

A
  • Neonatal respiratory distress syndrome more common in premature babies born six or more weeks.
  • Seen in premature infants with lack of surfactant ( a substance that lowers surface tension of fluid lining the alveoli, allowing the alveoli to remain expanded and promote gaseous exchange)
  • Without surfactant the alveoli are unable to stay inflated , and collapse when the baby exhales
  • Clinical signs- Dyspnea- shortness of breath- hypoxia
  • Imaging- AP mobile chest
  • RADIOGRAPHIC appearance- - Under aeration if the lung- Lungs have a granular appearance, ground glass appearance, hazy- Air bronchograms

  • IMAGING - CXR
    - Chest CT
  • RADIOGRAPHIC APPEARANCE- Hyperinflation of the lung
    P. - Late stage: Brochiectasis
