エアウェイスコープと気管支ファイバースコープを使用し経鼻気管挿管しえた巨大喉頭蓋嚢胞の1症例

摘要

A 26-year-old man was scheduled for surgical extraction of a large epiglottic cyst. Mask ventilation was possible under propofol anesthesia without muscle relaxant. It was difficult to see the glottis using either a Macintosh laryngoscope or by fiberoptic bronchoscopy. When the AWS laryngoscope (Hoya, Tokyo Japan) with a part of the blade removed, was inserted orally, it became possible to see the glottis with a part of the epiglottic cyst. A reinforced tube was inserted nasally, and a fiberoptic bronchoscope was passed through the tube into the trachea. The tube was then passed over the fiberscope into the trachea.We believe that the Pentax AWS laryngoscope may lift the epiglottis and its cyst atraumatically, and may facilitate nasal fiberoptic intubation in a patient with a large epiglottic cyst.
