[A case of difficult ventilation during resection of an intratracheal carcinoid tumor].

There is difficulty in airway management during intratracheal operation. We experienced airway obstruction during resection of an intratracheal carcinoid tumor using YAG laser. A 65-year-old woman was diagnosed with an intratracheal carcinoid tumor. The intratracheal tumor existed closely to the vocal cords and the middle of the trachea. Preoperative examinations of the blood gas and respiratory functions were normal. Under general anesthesia, LMA was inserted and control ventilation was performed during tumor resection. Gradually ventilation became difficult and SpO2 dropped necessitating tracheal intubation. A part of the tumor fell away and ventilation became easier. The operation was completed without major complications.
