In the previous study on mannekin, the investigators found stylet-assisted lifting of epiglottis is an useful technique on difficult airway (Cormack-Lehane grade IIIa, IIIb) without increasing subjective difficulty. It has no expenses other than the routine intubation process. Recently, the studies have proved that the bougie-assisted laryngoscopy can improve first pass intubation rate in the emergency department. However, bougie is a disposable device and may increased medical expenditure. The investigators will evaluate the safety of bougie and epiglottic lifting technique, as well as the first pass and overall success rate of intubation comparing to traditional video laryngoscopy and direct laryngoscopy.
A better strategy of managing Cormack-Lehane Grade III had been investigated by our previous study. The investigators' research results had been accepted and published by the journal BioMeidcal Central Anesthesiology. The investigators will be eager to do the further clinical trial to investigate the impact of this technique clinically. Besides, bougie assisted intubation is a effective, evidenced-proved intervention. The investigators will also like to find out the prognosis differences between these two techniques.
