The Importance of Early Detection and Therapy of Reexpansion Pulmonary Edema

Abstract

Three cases are reported of unilateral pulmonary edema, two following rapid reexpansion after prolonged tension pneumothorax, with total collapse of the right lung and one after reexpanded atelectasis following left intrabronchial obstruction. In all cases decrease of blood pressure and tachycardia not responding to intravenous fluid substitution were already present within the first 15 min after chest drainage or after removal of the intrabronchial obstruction. The preexistent dyspnea failed to improve. A cloudy opacity of the reexpanded lung was found immediately after drainage in 2 cases. After immediate application of a continuous positive airway pressure mask no more extensive therapy was necessary in one patient. The two others in whom treatment was begun with more than 1 hour delay required artificial ventilation and adrenergics for 2 and 4 days, respectively.
