AbstractAnesthesia for the tracheobronchial stent placement involves the risk of airway narrowing and obstruction. Controlled ventilation with relatively high airway pressure is usually used to maintain oxygenation and ventilation during anesthesia. However, controlled ventilation does not always provide tidal volume and oxygenation due to gas leakage from tracheobronchial fistula. We report 2 cases of general anesthesia under spontaneous respiration for the airway stent placement to treat tracheal and bronchial fistula. Case 1; A 55-year-old man with tracheoesophageal fistula due to the esophageal cancer was scheduled for the stent placement. Anesthesia was given with dexmedetomidine and sevoflurane preserving spontaneous respiration. The surgery was performed without complications of hypoventilation and hypoxemia throughout the procedure. Case 2; A 71-year-old woman developed empyema with large bronchopleural fistula as the result of the complication of radiation for the breast cancer. The stent placement was scheduled for closure of the fistula. Anesthesia was induced with remifentanil and sevoflurane with spontaneous respiration. When inserting the rigid bronchoscope, cough reflex occurred and propofol was added to deepen the anesthesia. The stent placement was performed with general anesthesia under spontaneous respiration without any complications.
