[Successful Use of the i-gel and Dexmedetomidine for Tracheal Resection and Construction Surgery in a Patient with Severe Tracheal Stenosis].

A 51-year-old man, 170 cm, 86 kg, was diagnosed with a tracheal tumor existing just below the glottis occupying more than 80% of his tracheal lumen, and was scheduled for tracheal resection and construction. The patient had a strider due to the severe tracheal stenosis. We could insert i-gel easily under dexmedetomidine sedation. After successful i-gel insertion, tracheotomy and endotracheal intubation were performed. Until ETT insertion, the patient maintained spontaneous respiration without any hypoxic event. Followed by ETT insertion, tracheal resection and construction were performed under general anesthesia. After the operation, the patient was extubated and transferred to the intensive care unit (ICU), where he was given DEX infusion to keep the tracheal anastomosis immobilized. There was no serious complication during the perioparative period.
