Malignant pneumomediastinum: successful tube mediastinostomy in the neonate.
Five critically ill neonates underwent tube mediastinostomy in the neonatal intensive care nursery for tension pneumomediastinum. All of the neonates showed immediate clinical improvement, with a decrease in peak airway pressure and elevation of arterial oxygen pressure levels. There were no complications directly attributable to the procedure. We believe that pneumomediastinum in association with severe hypoxia, metabolic acidosis, and high ventilation pressures indicates clinically significant tension in the mediastinum. This results in a decrease in systemic blood pressure and pulmonary venous return that is not amenable to conservative management. Needle aspiration is inadequate because of the dynamic nature of the air leak. Tube decompression of the mediastinum is the treatment of choice in these circumstances.
