Brief Summary

How to quickly expose glottis and accurately insert double luminal tracheal tube in patients with difficult airway in thoracoscopic surgery has become an urgent problem in anesthesia induction.This study through the double cavity bronchial tube visual laryngoscope intubation with open mouth and electronic video laryngoscope used in combination, to explore whether can shorten the glottis exposure, improve the success rate of the double lumen tube intubation will reduce pharyngeal damage, reduce intubation hemodynamic fluctuations, in order to improve the glottis appeared difficult patients with bronchial intubation success rate to provide the reference.

Conditions

Difficult Airway Intubation; Double-lumen Tube

Keywords

video laryngoscop; double-lumen tube; mouth gag

Outcome Measures

Primary Outcomes (5)

• Glottis exposure time

  through study completion, an average of 1 minute

• Bronchial intubation time

  through study completion,an average of 1 minute

• The number of intubation

  through study completion,an average of 1 minute

• One-time success rate of intubation

  through study completion,an average of 1 minute

• Glottic field grading

  Cormack-Lehane grading, C-L1：Can see glottis mostly；C-L2：Only the posterior union of the glottis is visible, not the glottis, and at most the cartilago arytaenoidea is visible when the larynx is lightly pressed；C-L3： can't see any part of the glottis, only the epiglottis； C-L4：No part of the larynx can be seen

  through study completion,an average of 1 minute
