Background:
Pulmonary interstitial emphysema (PIE) represents a severe complication of respiratory distress syndrome and can dramatically impair the ventilation of premature infants.
Objectives:
We report three mechanically ventilated premature infants with severe diffuse, unilateral PIE not responding to conventional treatment, whose clinical condition improved dramatically following an ipsilateral pneumothorax.
Results:
In the first two patients, the pneumothoraces occurred spontaneously. In the third patient, the ipsilateral lung was punctured with a pigtail catheter to create and - subsequently drain - a pneumothorax. Thereafter, mechanical ventilation could be discontinued within 3 days in all infants.
Conclusions:
Lung puncture with consecutive tension release of the overinflated lung by drainage is a therapeutic option for premature infants suffering from diffuse PIE in whom other conservative measures fail. It may be considered before proceeding to surgical measures in order to preserve potentially functional lung tissue.
