Intraoperative alveolar rupture due to barotrauma is very critical during and after anesthesia, because it can induce pneumothorax, pneumomediastinum, pneumoperitoneum and subcutaneous emphysema resulting in acute respiratory distress. The mortality rate of acute mediastinitis associated with pneumomediastinum has been reported to be 10 50% depending on the study groups. This wide range of mortality is thought to be resulted from patient selection and management approaches. Mechanical problems of anesthetic machine may also relult in intraalveolar rupture. We report a case of a 23-year- old female patient who developed pneumomediastinum caused by the failure of the scavenging system of anesthetic machine.
