[Anesthetic management of tracheobronchial stent insertion and extracorporeal lung assist (ECLA)].

We experienced eight cases of general anesthesia for tracheobronchial stent insertion. All stents were Ultraflex stent (Boston Scientific, Tokyo), and they were inserted guided by bronchofiberscopy under general anesthesia. Anesthesia was induced with patients under spontaneous breathing, and we inserted a tracheal tube or a laryngeal mask airway. Anesthesia was maintained with propofol and sevoflurane. In four cases with severe tracheobronchial stenosis, we used venovenous extracorporeal lung assist (ECLA) before general anesthesia induction. Oxygenation during stent insertion was well-maintained in all patients. We must evaluate the severity of tracheobronchial stenosis preoperatively. In high risk cases anticipated of airway obstruction, ECLA should be used for safe anesthetic management.
