Meconium aspiration syndrome is treated as an emergency when a newborn has breathing difficulty.
In a hospital or birth centre, the maternity team will call staff trained in newborn resuscitation.
Call emergency services immediately after a home birth or after discharge if a newborn:
During pregnancy or labour, contact your maternity unit promptly if your waters are green or brown, your baby's movements have reduced, or you have been told to seek care for a change in movements.
Meconium-stained fluid without breathing symptoms is not itself a diagnosis, but it needs professional assessment.
Routine follow-up is appropriate after discharge if your baby is breathing comfortably but has concerns with feeding, weight gain, coughing, wheezing, hearing, movement, or development.
Bring these concerns to the baby's scheduled clinician or newborn follow-up team.
