case_images: Anesthesia record. Details of events (1-6). (1) Glossoptosis was caused by initiation of sedation, and ventilation became difficult. It was resolved by airway intubation. (2) Initiation of spontaneous breathing. (3) AEC (Cook Airway Exchanger Catheter  8.0 Fr) was inserted and placed, and the tracheal tube was removed. (4) An otolaryngologist confirmed the glottis by endoscopy. No problem with the vocal cord or upper airway tissue was noted, and AEC was removed. (5) Spontaneous breathing was favorable, but airway obstruction by glossoptosis was noted. Thread to pull the tongue was placed on the tongue tip during surgery, and obstruction was improved by pulling. (6) The postoperative course was observed in an ICU. Dexmedetomidine was administered for sedation, but no problem with the respiratory condition occurred, and the patient was transferred to a general ward. ( ) Operation room in/out. (x) Anesthesia start/completion. (T) Endotracheal intubation. ( ) Completion of induction. ( ) Surgery start/completion. (E) Endotracheal extubation
