Meconium exposure in amniotic fluid can cause which condition in the newborn?

Explanation:
When meconium is present in the amniotic fluid and the newborn inhales it, the lungs undergo chemical irritation and inflammation, leading to a form of chemical pneumonitis known as meconium aspiration syndrome. The inhaled meconium blocks small airways, damages the airway and alveolar surfaces, and inactivates surfactant, all of which impair gas exchange and can cause respiratory distress and hypoxemia. This mechanism is distinct from jaundice (bilirubin-related), allergy-driven respiratory symptoms, or gastroenteritis, which are not the direct outcomes of in utero meconium exposure.
