What Causes Pneumothorax in Newborns?

Pneumothorax in newborn refers to the accumulation of gas in the pleural cavity of the newborn, most of which is caused by the escape of the mediastinal emphysema or the pleural bulge into the pleural cavity. It can be spontaneous pneumothorax or secondary to disease, trauma, or surgery. Pneumothorax usually occurs suddenly and the symptoms are more dangerous.
