[Sevoflurane inhalation reduced bronchospasm after extubation].

A 73-year-old female was scheduled for left upper lobectomy. She had no history of asthma or chronic obstructive pulmonary disease. During the operation, respiratory sound was clear. As spontaneous breathing was regular and stable after the reversal of neuromuscular blockade, an endotracheal tube was extubated. But soon after the extubation, wheezing and gasping respiration occurred and she complained of dyspnea. Therefore, we administered aminophylline and steroid intravenously, and the patient's lungs were ventilated manually with 100% oxygen. But after 10 minutes, there was no improvement in symptoms, and sevoflurane inhalation was started immediately. Inspiratory sevoflurane concentration was 4% at first, and was decreased to 2%. About 20 minutes after starting sevoflurane inhalation, wheezing was reduced. Sevoflurane may be useful in the treatment of bronchospasm after extubation.
