Outcome Measures
Primary Outcomes (1)
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
Study Arms (2)
ultrasound group
EXPERIMENTALpatient using ultrasound technique.probe will be placed over submandibular area, the thyrohoid muscle and thyrohyoid membrane will be identified between greater horn fo hyoid bone and thyroid cartilage , 3 ml of lignocaine will be placed on space between thim and the procedure will repeated on contra lateral side.
anatomical blind group
ACTIVE COMPARATORpatient using anatomical land mark technique, internal branch of superior laryngeal nerve will be blocked slightly anterior to greater horn of hyoid bone . by 3 ml lignocaine . the procdure will be repeated on contra lateral side .
Interventions
evaluate the effect of ultrasound guided technique for block of internal branch of superior laryngeal nerve
