How is neonatal pneumothorax caused?

Neonatal pneumothorax can be divided into the following three categories according to the causes: First, spontaneous pneumothorax, is in the absence of trauma or human factors, lung tissue and pleural rupture caused by pneumothorax, due to term infants respiratory movement strong, so the incidence of term infants is high. 2. Iatrogenic pneumothorax mostly occurs during asphyxia resuscitation. Due to improper use of breathing sachets, excessive pressurization or excessive pressure during mechanical ventilation, pneumothorax occurs due to alveolar rupture. With the standardization and popularization of asphyxia resuscitation technology in the delivery room, The incidence of this type of pneumothorax has been declining year by year. Due to the widespread use of ventilators in neonatal intensive care units in recent years, pneumothorax also occurs during mechanical ventilation. III. Pathological pneumothorax refers to pneumothorax occurring on the basis of primary lung disease. The clinical characteristics of this kind of pneumothorax are severe symptoms, relatively large lung compression area, compression of about 30% to 70%, and mechanical ventilation and closed thoracic drainage are required.
