title: Acid pulmonary aspiration syndrome after antacids. A case report.
abstract: This is a report of a patient who developed acid pulmonary aspiration syndrome following pulmonary aspiration of gastric contents at a pH of 3.5. The volume of the stomach contents was large and 15 ml of magnesium trisilicate was insufficient to prevent the effects of acid aspiration. After operation, considerable pulmonary shunting was demonstrable for several days. The patient was discharged home well, and a chest x-ray 2 months later showed no abnormality.
