Brief Summary
To measure the distance between the upper edge of the thyroid cartilage to the upper edge of the sternum add the distance from the upper edge of the sternum to the carina was calculated according to the chest CT scans as a guide to the placement of Uniblocker without the aid of FOB.

Outcome Measures
Primary Outcomes (1)
The intubation time
The intubation time defined as the time from the anesthesiologist inserted the video laryngoscope between the teeth of patients until Uniblocker at the optimal position and this was done using a stopwatch.
