Which of the following is a potential complication of Meconium Aspiration Syndrome (MAS)?

• A. Pneumothorax
• B. Congenital heart disease
• C. Respiratory syncytial virus infection
• D. Bronchopulmonary dysplasia

Answer: (A)

Meconium Aspiration Syndrome (MAS) occurs when a newborn inhales a mixture of meconium and amniotic fluid into the lungs before or during delivery, which can lead to a range of respiratory problems. Among the potential complications that newborns with MAS may experience, pneumothorax is a significant concern. This condition can arise due to the combination of airway obstruction and increased intrathoracic pressure, which may lead to a rupture in the alveoli, causing air to enter the pleural space and resulting in a pneumothorax.

The mechanisms that might lead to pneumothorax in MAS include the accumulation of meconium in the airways, which can cause partial or complete obstruction, leading to atelectasis of lung areas. This, combined with the effort of breathing against an obstructed airway, places additional stress on the lung structure and can contribute to the formation of a pneumothorax.

Looking at the other options, congenital heart disease is not directly a complication of MAS, as it typically arises from structural anomalies during fetal development. Respiratory syncytial virus (RSV) infection is a viral infection that might affect infants but is not a complication specifically associated with MAS. Bronchopulmonary dys
