简要总结
This isobservational analytical study to determine the utilityof ultrasound measurement of the anterior neck soft tissue thickness at hyoidand thyrohyoid level and Tongue thickness in predicting difficult and easylaryngoscopy.
Conventionalclinical screening tests like MMP, inter incisor gap, thyromental distance, sternomentaldistance will measured during preoperative assessment. Ultrasoundmeasurement of the anterior neck soft tissue thickness at hyoid and thyrohyoidlevel and Tongue thickness will be measured on the day of surgery beforeinduction of anesthesia in supine and sniffing position in operation theatre. Directlaryngoscopy will be performed. Ultrasound guided measurements will be comparedwith conventional clinical screening tests to predict difficult laryngoscopy.

结局指标
主要结局
Cormack Lehane laryngoscopy grading will be assessed and Grade 3 and grade 4 will be categorized as difficult intubation (outcome)
时间窗: Cormack lehane grading of laryngeal view will be assessed at the time of laryngoscopy after administration of general anaesthesia at operation room.
次要结局
- To compare the ultrasound guided measurement of anterior soft tissue neck and tongue thickness with conventional screening test to predict difficult laryngoscopy(Cormack Lehane grading of laryngeal view will be assesed during laryngoscopy after administration of anaesthesia and grade 3 and 4 will be considered as difficult intubation)
