What caused Meconium Aspiration?

The baby had a bowel movement while still inside the mother’s uterus. Meconium is the name for the first stools that a baby passes. The meconium gets into the fluid surrounding the baby and can be swallowed into the lungs or breathing passageways prior to or at the time of birth. Babies that are under stress or go beyond their expected due date have a higher incidence of passing meconium while still in the uterus. Generally, meconium aspiration is seen in babies that are not premature.
