Cas CliniquePneumomédiastin et emphysème sous-cutané au décours d'une ventilation translaryngée par oxygène pulséMediastinal and subcutaneous emphysema secondary to emergency translaryngeal jet ventilation

The use of emergency transtracheal jet ventilation in a 62 year-old female with laryngeal papillomatosis and respiratory distress is reported. Adequate ventilation of the lungs with an intermittent jet of oxygen under high pressure (5 bar) allowed anaesthesia and surgery to be carried out. Pathogenesis of the mediastinal and subcutaneous emphysema discovered at the end of the procedure is discussed.
