Meconium aspiration occurs secondary to intrapartum or intrauterine aspiration of meconium, usually in the setting of fetal distress, and usually in term or post-term infants.
Aspirated meconium can cause small airways obstruction and a chemical pneumonitis.
- high lung volumes (secondary to small airway obstruction)
- asymmetric, patchy pulmonary opacities
- pleural effusions can be seen
- pneumothorax in 20-40% of cases (secondary to small airway obstruction)
