Aspiration pneumonitis was suspected. The chest x-rays taken in PACU showed lung infiltration in both cases and arterial blood gases revealed hypoxemia. During anesthesia, there were brief episodes of choking, regurgitation, and desaturation, which were improved by giving high FiO2 and positive pressure ventilation. The diagnosis and management of aspiration pneumonitis was discussed.Mahidol UniversityMedicineArticleSCOPUS
