title: [Pulmonary edema due to laryngospasm immediately after extubation].
abstract: We describe a case of negative pressure pulmonary edema (NPPE) followed by laryngospasm occurred immediately after extubation. A 56-year-old man with a tumor at the site of ureteroneocystostomy underwent left ureterectomy and partial resection of the neobladder under general anesthesia. The tracheal intubation was difficult with glade 3 of Cormack classification. Anesthesia was maintained with sevoflurane, nitrous oxide, and oxygen. After fully awake extubation, the upper airway obstruction due to laryngospasm was observed. A nasal airway was inserted, but face mask ventilation was impossible. Ventilation became possible with SpO2 of around 40%, and spontaneous respiration appeared. The patient was nasally intubated with a fiberoptic bronchoscope. Furosemide was administered in ICU and mechanical ventilation with 5cmH2O PEEP was started. Seventeen hours later, the pulmonary edema disappeared and he was successfully extubated without any complications. It was warned that laryngospasm would occur even after the full emergence, leading to NPPE.
