Can meconium cause brain damage?

If meconium is inhaled or ‘aspirated’ and is not cleared from the baby’s airway and lungs as soon as the baby is born and needs to breathe in air, it can block the baby’s airway, leading to oxygen deprivation, brain injury and, ultimately, death.

Does meconium affect the mother?

Meconium may enhance the growth of bacteria in amniotic fluid by serving as a growth factor, inhibiting bacteriostatic properties of amniotic fluid. Many adverse neonatal outcomes related to MSAF result from meconium aspiration syndrome (MAS). MSAF is associated with both maternal and newborn infections.

Can meconium aspiration cause death?

Meconium aspiration syndrome occurs when a newborn breathes a mixture of meconium and amniotic fluid into the lungs around the time of delivery. Meconium aspiration syndrome, a leading cause of severe illness and death in the newborn, occurs in about 5 percent to 10 percent of births.
