简要总结
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.
详细描述
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.

研究组 & 干预措施
ultrasound group
patient 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.
干预措施: ultrasound technique (Device)
anatomical blind group
patient 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 .
干预措施: ultrasound technique (Device)
结局指标
主要结局
assessment the quality of airway anesthesia
时间窗: Up to 2 years post baseline
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.
