[Pulmonary oedema after a knee arthroscopy].

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.
