[Tracheal intubation for emergent tracheostomy in a patient complicated with tracheal stenosis].

We report the management of anesthesia for emergent tracheostomy in a patient with severe tracheal stenosis. A 63-year-old male was scheduled for an emergency tracheostomy for severe tracheal stenosis due to the invasion of a thyroid cancer. A preoperative neck CT revealed the tracheal stenosis, extending from 1-2 cm below the vocal cord to the upper end of the sternum. The narrowest caliber was about 7 mm in transverse diameter. Moreover, the cancer was suspected to have a bleeding tendency. General anesthesia with endotracheal intubation was considered necessary to provide an open airway during tracheostomy. Anesthesia was induced with thiopental, and a 6.0 mm endotracheal tube with cuff was successfully introduced with a balloon introducer (AIRGUID E) using suxamethonium. We were able to perform tracheostomy uneventfully.
