Newborn respiratory distress syndrome

Also called NRDS, Infant respiratory distress syndrome, or Hyaline membrane disease

Newborn respiratory distress syndrome happens when a baby's lungs are not fully developed and cannot provide enough oxygen. It mainly affects premature babies, because their lungs do not yet make enough surfactant, a substance that keeps the air sacs open. Symptoms usually start within minutes or hours of birth.

What it is

If an early birth is expected, steroid injections given to the mother can help the baby's lungs mature.

Babies are treated in a neonatal unit with breathing support, oxygen and surfactant given into the lungs. Most recover.

Common signs

  • Fast, shallow breathing
  • Grunting
  • The skin between the ribs pulling in with each breath
  • Flaring nostrils
  • Blue lips or skin

How it is usually diagnosed

  • Examination of the baby
  • Chest X-ray
  • Blood oxygen tests

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Neonatal unit discharge summaries
  • Follow-up clinic letters
  • Pregnancy notes about steroids given

Questions to ask your doctor

  • How long might my baby need breathing support?
  • Are there any long-term effects to watch for?
  • What follow-up will my baby have?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A baby who is struggling to breathe, grunting or turning blue: call 112
