Complications in airway management remain a common cause of anesthesia-associated mortality. When a patient is considered with anticipated difficult airway, the management depends on several variables, however, at present, the standard of management continues to be the patient awake approach. In scenarios of acute upper airway obstruction, the only way to guarantee adequate ventilation is to obtain a translaryngeal or transtracheal access, for which, it is necessary to use local anesthesia and grade I / II sedation, avoiding loss of spontaneous ventilation. For this purpose, we propose ultrasound-guided superior laryngeal nerve block, in order to standardize an ultrasound landmark that is reproduceable, with a high success rate, which allows limiting complications related to regional anatomic techniques and thus facilitating the securing of the airway in these patients.
