Spontaneous pneumothorax is a common disorder that is easily recognized and treated. Occasionally reexpansion of the collapsed lung is complicated by unilateral pulmonary edema, heralded by tachypnea, unilateral rales, and profuse expectoration of frothy secretions within several hours of reexpansion. Severe morbidity and death may result. Increased duration of pneumothorax and the use of suction are important factors in the generation of reexpansion pulmonary edema. Increased pulmonary capillary permeability rather than hydrostatic transudation is believed to underlie its development. For patients with pneumothorax of prolonged duration close observation in an intensive care unit for 24 hours after evacuation of air and the routine use of supplemental oxygen during and after lung reexpansion seem indicated.

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.

Pneumothorax may be classified as open or closed and as traumatic, spontaneous, or iatrogenic. The most common cause of pneumothorax is thoracic trauma. Spontaneous pneumothorax is often a result of bullous emphysema, and iatrogenic pneumothorax is an important complication of procedures involving the thoracic cavity. Most animals present with tachypnea, tachycardia, respiratory distress, and anxiety. Radiography and thoracocentesis are useful diagnostic aids. Traumatic and iatrogenic pneumothorax are commonly treated with thoracocentesis or thoracostomy tube placement. Spontaneous pneumothorax usually requires surgical resection of the affected lobe(s). The prognosis for traumatic pneumothorax is excellent if there are no other life-threatening injuries; for spontaneous pneumothorax, the prognosis depends on the underlying cause and method of treatment. The prognosis for iatrogenic pneumothorax is considered good.Pneumothorax is classified as open or closed and according to the causative mechanism. Open pneumothorax results from a penetrating thoracic injury that permits entry of air into the chest, while closed pneumothorax is the accumulation of air originating from the respiratory system within the pleural space. In some cases, the air may come from both sources (e.g., severe thoracic bite wounds with lung punctures).
