[Paradoxal gazous embolism in hepatic trauma. Contribution of hyperbaric oxygenotherapy]. / Embolie gazeuse peropératoire chez un traumatisé hépatique. Intérêt de l'oxygénothérapie hyperbare.

A young man was admitted for a polytraumatism associating head trauma and blunt abdominal trauma with hepatic injury. He was managed with a damage control surgery with a perihepatic packing. During the second look surgery, he developed a paradoxal gazous embolism by air aspiration in the sus-hepatic vein. This has never been described before in such traumatism. The patient presented a respiratory distress, a circulatory shock due to right infarction and an intracranial hypertension with bilateral mydriasis. He was immediately treated by hyperbaric oxygenotherapy. The evolution was good and he recovered without sequelae.

[Pulmonary oedema after a knee arthroscopy]. / Oedème pulmonaire après une arthroscopie du genou.

Negative pressure pulmonary oedema is one form of non cardiogenic pulmonary oedema that can occur following any general anaesthesia in which the patient was intubated. This complication can be severe, resulting in death/life-threatening if not diagnosed and treated promptly. We report a case of negative pressure pulmonary oedema, in a 26-year-old man, secondary to inspiratory effort with laryngeal spasm. Patient was transferred to intensive care unit for monitoring and non invasive ventilation. Prevention, early diagnosis, and prompt treatment allowed a rapid and uncomplicated resolution.
