What is a characteristic sign of meconium aspiration syndrome?

1. Nasal flaring

2. High fever

3. Continuous crying

4. Swollen abdomen

The correct answer is: Nasal flaring

Nasal flaring is a characteristic sign of meconium aspiration syndrome because it indicates respiratory distress in the newborn. When a baby inhales meconium-stained amniotic fluid during or before delivery, it can obstruct the airways and lead to inflammation and reduced oxygen levels. As a result, the infant may exhibit signs of respiratory distress, including nasal flaring, which is a compensatory mechanism indicating that the baby is struggling to breathe. It reflects increased effort and indicates that the baby is trying to take in a sufficient amount of air. Other signs of respiratory distress can include retractions or grunting, but nasal flaring is a specific, observable sign often noted in clinical practice. Understanding this symptom is crucial for healthcare providers to identify and manage potential complications associated with meconium aspiration syndrome effectively. Recognizing nasal flaring early allows for timely interventions to ensure that the newborn receives appropriate respiratory support and monitoring.
