Ultrasound-Guided Glossopharyngeal Nerve Block for an Awake Intubation in a Patient Predicted to Have a Difficult Airway: A Case Report.

Abstract

A peripheral nerve block may be used to improve patient tolerance of awake intubation. During an awake intubation, the glossopharyngeal, superior laryngeal, and recurrent laryngeal nerves can mediate discomfort, pain, cough, glottic closure, and gag reflexes. We describe the use of ultrasound-guided superior laryngeal, recurrent laryngeal, and glossopharyngeal nerve blocks to facilitate awake intubation in a patient predicted to have a difficult airway. The glossopharyngeal nerve block was performed via the parapharyngeal space approach targeting the distal glossopharyngeal nerve. This procedure resulted in an uneventful awake intubation.
