Design outcomes

Primary

Measure	Time frame
To compare the success rate of the first intubation attempt using direct laryngoscopy in two different techniques?the conventional sniffing position versus the left head rotation (LeHeR) technique?in patients with an anticipated difficult intubation.Timepoint: Airway assessment in preoperative area, at the time of laryngoscopy and endotracheal intubation	—

Secondary

Measure	Time frame
1. To compare the time to endotracheal intubation between the two groups. 2. To compare the Cormack-Lehane (CL) grading in both techniques. 3. To compare the number of attempts to successful intubation 4. To compare the use of external laryngeal manipulation. 5. To compare the use of adjuncts (stylet, bougie) between two techniques. 6. The need for greater expertise during endotracheal intubation. Timepoint: At the time of laryngoscopy & endotracheal intubation	—
