Meconium aspiration refers to...

Meconium aspiration specifically refers to the inhalation of meconium-stained amniotic fluid by a newborn during or shortly after birth. Meconium is a thick, greenish substance that is the first stool of an infant, composed of various materials including intestinal cells, lanugo, and bile. If the fetus has a bowel movement in utero and subsequently inhales this meconium, it can lead to respiratory issues, as the thick substance can block airways and irritate lung tissue.

Recognizing meconium aspiration as a condition highlights the importance of close monitoring during labor and delivery, especially if meconium is present in the amniotic fluid. By understanding meconium aspiration, healthcare professionals can take steps to manage and mitigate potential complications for the newborn.
