It can make it difficult for the baby to breathe by irritating the airways, affecting the way the lungs expand, or partially or completely blocking the baby’s airways, essentially reducing the amount of … This patient’s lung ultrasonography showed large areas of pulmonary consolidation with air bronchogram and clear edges in the right lung that were consistent with atelectasis. Infection is probably the most common complication associated with MAS. problems. In addition, meconium inactivates surfactant, leading to secondary surfactant deficiency (Moses et al, 1991). The severity of MAS will depend on how much meconium the baby has inhaled. The aspirated meconium can partially or completely block the baby's airways, making it difficult for the infant to breathe and causing irritation or a lung infection. doctor may recommend inducing labor to help When partial obstruction occurs, it causes a ball valve effect with increased air trapping, thus increasing the risk of air leak syndromes, notably pneumothorax.

Last medically reviewed on March 14, 2018. Pulmonary surfactant, the complex combination of chemicals that line the surface of the lung, may be altered or inactivated in babies who have meconium aspiration. This gasping usually happens because a problem (such as an infection or compression of the umbilical cord) made it hard for the baby to get enough oxygen before birth. What is the outlook for newborns with MAS? Five common treatments include: Most newborns with MAS won’t have any long-term health complications. As a result, MAS is more common in overdue newborns as compared to term newborns. Meconium can affect the lungs in the following ways - It can be an irritation to the lung tissue; It can cause obstruction of the airways with a 'plugs' of meconium Meconium staining of the amniotic fluid (MSAF) is found in approximately 15% of pregnancies. © 2005-2020 Healthline Media a Red Ventures Company.

When babies take their first breaths at birth, bits of meconium can enter the airway. Early detection is the best defense in preventing MAS.
