[Severe laryngeal edema after tracheal extubation--report of a case].

An 80-year old female underwent subtotal esophagectomy with neck lymphnode dissection for esophageal cancer. The tracheal intubation was done repeatedly. Anesthesia was maintained with O2-N2O-isoflurane. No complications were observed during the operation. About thirty minutes after tracheal extubation, she developed airway obstruction with tracheal tug and stridor. Severe laryngeal edema was found by bronchofiberscopy. Percutaneous minitracheostomy was performed under ventilation support by laryngeal mask airway. Seven days later, bronchoscopy examination revealed that the laryngeal edema had disappeared. It should be kept in mind that severe laryngeal edema could develop immediately after extubation.
