54 participants in 2 patient groups

neck flexion first

Experimental group

Description:

With specific head posture, intubation is done under flexible fiberoscopy guide. In this arm, at the position with neck flexion, fiberoscopy is pulled into the mouth and get the photo of laryngeal view. After then, neck position is changed to neck extension, And the laryngeal view is gotten in the same way.

Treatment:

Procedure: Intubation

neck extension first

Experimental group

Description:

In this arm, at the position with neck extension, fiberoscopy is pulled into the mouth and get the photo of laryngeal view. After then, neck position is changed to neck flexion, And the laryngeal view is gotten in the same way.

Treatment:

Procedure: Intubation
