title: Spontaneous pneumothorax in the newborn.
abstract: Spontaneous pneumothorax is more frequent during the newborn period than at any other time in childhood. Intubation, vigorous resuscitation, aspiration of meconium-stained amniotic fluid, and hyaline membrane disease have been associated most often with the occurrence of spontaneous pneumothorax; however, it may occur in the absence of any of these precursors. Most pneumothoraces occur in term babies (64%); however, the premature infant is more susceptible. Signs and symptoms are due chiefly to lung compression and include grunting, tachypnea, cyanosis, and retraction. The accumulation of air serves as an intrathoracic space-occupying lesion, an emergency condition that demands prompt diagnosis and treatment.
