Final answer:
Meconium Aspiration Syndrome (MAS) is a condition where a newborn inhales meconium into the lungs. It can lead to complications such as pulmonary artery hypertension and pneumonitis. Intubating and suctioning the airways should be done before other interventions.
Step-by-step explanation:
Meconium Aspiration Syndrome (MAS) is a condition where a newborn inhales meconium, the baby's first stool, into the lungs. This can occur during childbirth when the baby passes meconium into the amniotic fluid. Meconium aspiration can lead to complications such as pulmonary artery hypertension, pneumonitis, and an increased vulnerability to pulmonary infections. The aspiration of meconium can be identified by a coarse rattling sound in the lungs and confirmed through blood gas tests and chest X-rays. To manage the condition, it is recommended to intubate and suction the baby's airways before any other stimulation.
