Clinical Trial Summary

Macintosh direct laryngoscope has been mostly widely used for anesthesiologists in operation rooms or emergency situations all over the world. With rapidly development of technical devices, nowadays videolaryngoscope has become more and more popular in hospitals, for it could improve first intubation success rate and it is easier for beginners to learn. And there are many different types of videolaryngoscope for different purpose, like with or without a channel, different curvature, and so go. In this study, our aim is to study whether the videolaryngoscope which can be adjustable or not costs less intubation time and causes fewer injury in expected non-difficult airway patients by experienced anesthesiologists, compared with the classic Macintosh direct laryngoscope.

• Laryngoscopes

Intervention

Device:
• The laryngoscope used for tracheal intubation under general anesthesia for patients with expected non-difficult airway conditions.
All the patients will receive the same anesthesia induction, and are randomized to three groups to receive different types of laryngoscope for intubation. These are the direct Macintosh laryngoscope, adjustable videolaryngoscope and nonadjustable videolaryngoscope.

Primary	Tracheal intubation time	total time to successful orotracheal intubation	time from the removal of the patient's face mask for preoxygenation to confirmation of good tube position based on continuous positive end-tidal carbon dioxide reading (at least three breaths without a significant visual decrease in capnography).
