Clinical Trial Summary

The aim of this study is to evaluate the effect of ultrasound guided technique for block of internal branch of superior laryngeal nerve in surgical patient in comparison to blind anatomical technique.

Description:

Airway anesthesia is pivotal for successful awake intubation provided either topically or by nerves blocks. Airway blocks are technically harder to perform with more complications possibilities. However, in experienced hands, they can be useful as they provide better intubating conditions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	assessment the quality of airway anesthesia	The Quality of Airway anesthesia will be graded as: 0 = no coughing or gagging in response to intubation, 1 = mild coughing or gagging that will not hinder intubation, 2 = moderate coughing or gagging that will interfere minimally with intubation,3 = severe coughing or gagging that make intubation difficult and 4 = very severe coughing or gagging that will require additional local anesthetic or change in technique to achieve successful intubation.	Up to 2 years post baseline
