Brief Summary

Several pre-operative airway assessment methods exist to predict difficult airway, but unexpected difficult endotracheal intubation may occur. These assessment criteria are not often useful in uncooperative patients and unconscious patients.  Most of the airway assessment criteria are objective in nature and are therefore prone to inter-observer variability. Also, the Cormack Lehane grading doesn’t always correlate with pre-op airway assessment parameters. Hence, the diagnostic accuracy by the pre-operative assessment technique remains inadequate for predicting difficult endotracheal intubation and there is still search for a simple, yet non-invasive way to provide more accurate prediction  about difficult airway. There are limited literature available comparing airway ultrasound parameters with difficult airway scoring system based on observation using direct laryngoscopy. Besides that, there is no available literature regarding ultrasonographic soft tissue thickness parameters of neck as a part of preoperative airway assessment in patients admitted to an Eastern Indian hospital. Therefore present study has been taken up to determine utility of ultrasound based airway assessment in evaluating difficult airway in patients admitted to an eastern Indian hospital.

Primary Outcome Measures

Name	Time	Method
To find out the sensitivity, specificity, positive predictive value and negative predictive value of ultrasonographic airway assessment parameters; Skin soft tissue thickness at level of Hyoid bone, Skin soft tissue thickness at level of vocal cords, distance from skin to epiglottis midway and ratio of the depth of the Pre-Epiglottic space to the distance from the epiglottis to the mid-point of the distance between the vocal cords (E-VC) for predicting a difficult airway.	1.ULtrasound examination of airway will be done before endotracheal intubation | 2. Intubation Difficulty score (IDS) assessment will be done during laryngoscopy and intubation

Secondary Outcome Measures

Name	Time	Method
To develop a scoring system for ultrasonographic airway assessment parameters, which best predicts a difficult airway.	Scoring system will be developed after analysis of data of all recruited patients
