Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Awake tracheal intubation is the standard management for patients as risk for airway compromise. It is also commonly done in cases where there is significant cervical spine pathology i.e. cervical myelopathy or instability. The anesthetic technique used for the awake intubation is crucial to the patient's safety. One of the most important aspects of the anesthetic technique is airway anesthesia prior to placement of an endotracheal tube. The superior laryngeal nerve is responsible for mediating the cough reflex around the vocal cords. The investigators have developed an approach to reliably block the superior laryngeal nerve by injecting local anesthetic near the nerve in a unique approach. Injecting local anesthetic into or through the thyrohyoid membrane will effectively block the superior laryngeal nerve

Assessment of Superior Laryngeal Nerve Block Technique

Superior Laryngeal Nerve Block using the Thyrohyoid Membrane as an Anatomic Landmark

Intervention Type PROCEDURE

The needle is introduced just lateral to midline above the thyroid notch in a slightly medial direction so as to enter the thyrohyoid membrane, and inserted about 1-1.5 cm. Three milliliters of 2% lidocaine is injected.
