Meconium is the baby’s first bowel movement. It is probably not what you expect. These first feces consist of debris, cells from the intestinal tract, mucus, and slimy fluids. Meconium is green and has no smell.
What is Meconium Aspiration Syndrome?
Meconium Aspiration Syndrome (MAS) causes respiratory distress as a result of meconium entering the respiratory tract below the vocal cords and presenting in the tracheal bronchial tree. When the baby makes an attempt to breathe in utero, before the baby is delivered, the baby can inhale meconium material into the lungs. The fear is the meconium blocking the airways. Oxygen is critical to life for all of us. But, during the birthing process, it is critical to have a smooth flow of oxygen to the brain and other vital organs.
