Design outcomes

Primary

MeasureTime frame
To evaluate the predictive validity of new index called the acromioaxillosuprasternal notch index (AASI) and compare it with a standard test mallampati test (MMP) for assessing difficult laryngoscopic viewTimepoint: We will measure aasi and modified mallampatti test in preoperative area and will compare it with cormack lahange grading which will be done after seeing vocal cord after laryngoscopy

Secondary

MeasureTime frame
Intubation difficulties, intubation attempt, failed intubation, hemodynamic parameters, complicationsTimepoint: Staring of induction of anesthesia to 15 minutes after intubation of trachea.
