EtiologyPredisposed in:
Cesarean birthDiabetic motherMaternal bleedingPremature birthPrenatal asphyxiaProlonged labor or Rapid laborSecond-born twin or sibling with IRDScaucasian males
PresentationClinical signs of respiratory distressABG’s show hypoxemia, hypercapnia and
respiratory acidosisSymptoms within the first 8 hours of lifePeak usually by third day“ground glass” appearance of the CXR
ManagementAntenatal
glucocorticoids (steroids)
Surfactant replacement therapy
Empiric antibiotic therapy
Thermoregulation
Avoid hypoxemia and acidosisPaO2 50-70mmHg
Optimize fluid management
Reduce metabolic demands
Minimize lung injuryCPAPVt 4-5ml/kgPEEP
