Background
Tracheobronchial stenting is a type of interventional respiratory therapy. In anesthesia management for rigid bronchoscopy, it is necessary to maintain an appropriate depth of anesthesia while maintaining spontaneous breathing. The usefulness of superior laryngeal nerve block (SLNB) in awake intubation is well known [1]. Recently, the usefulness of SLNB in airway stent insertion has been recognized, but there are few reports of ultrasound-guided SLNB. In a previous report, the combination of SLNB and total intravenous anesthesia (TIVA) reduced the respiratory depression associated with the use of propofol and fentanyl in anesthesia for rigid bronchoscopy [2]. Ultrasound-guided SLNB may be useful for reducing the dose of intravenous anesthetics, by reducing airway reflexes. We here report a case of a patient with airway stenosis caused by lung cancer, who underwent tracheal stent placement under rigid bronchoscopy. TIVA combined with ultrasound-guided SLNB enabled safe anesthetic management without any adverse events. We obtained written informed consent from the patient to publish this case report.
