Conditions

Endotracheal Tube

Brief summary

To observe the effect of additional E-tube angulation on intubation time and success rate.

Detailed description

The hypothesis of this study is that shaping endotracheal tube by end-to-end connection before induction will provide more optimal angulation for endotracheal intubation.

Interventions

OTHERCurved-tube

Connecting both ends of the endotracheal tube (O shape) for 5-min and releasing it provides additional anterior angle temporarily.
