[Meconium aspiration syndrome. Two cases treated with continuous positive airway pressure (author's transl)]

Two cases of Meconium Aspiration Syndrome successfully treated with CPAP are presented. In both patients the introduction CPAP enhanced arterial oxygenation. The A-a DO2 showed a decrease of 57 and 228 mm Hg respectively. After the introduction of CPAP it was possible to decrease the enviromental oxygen concentration and both patients survived. The possible mechanism by which CPAP improves hypoxia in MAS is discussed.
