Should parents be concerned if their child has been diagnosed with meconium aspiration syndrome?
Meconium aspiration syndrome (MAS) is a condition where a newborn breathes meconium (newborn’s first stools – thick, sticky, greenish-black color) and amniotic fluid into the lungs before, during, or after delivery. When a baby is under stress or not receiving enough oxygen or blood, the baby can pass feces while still in the uterus.
