Difficulty in Extubation due to the Cuff Adhesive Structure of a Tracheal Tube：A Case Report

要旨

　声門下腔吸引機能を有する気管チューブの使用は人工呼吸器関連肺炎を減少させると報告されている^1）。今回，われわれは声門下腔吸引の吸引効率を上げるためのカフ接着構造が抜管困難の原因となったと考えられた症例を経験したので報告する。

　We describe a case of difficulty in the extubation of a 82-year-old female patient due to the cuff adhesive structure of the tracheal tube used. At the first attempt to extubate the patient, the deflated cuff was caught in the patient’s subglottis and extubation was not possible. The cuff was inverted and glued in such a way that it folded. We observed that when the cuff was deflated, the area around the cuff deflected and expanded into a ring shape. This patient’s case emphasizes the need to take the potential necessity of further measures into consideration when a cuff adhesive structure and/or the tube size make extubation challenging.
