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.

Detailed Description

A total of 60 patients who needed double-lumen endobronchial catheterization in thoracic department and whose Arne o 'risk index score was at least 7 points were randomly divided into three groups.Group B was intubated with video laryngoscopy.Group C was intubated with a mouth opener for video laryngoscope combined with a double-lumen bronchial tube for video laryngoscope intubation (hereinafter referred to as the mouth opener).The glottis exposure time, bronchial intubation time, intubation times, success rate of one intubation, and NRS score of pharyngeal pain 8 hours after surgery were observed and recorded in the three groups, and the hemodynamic changes after intubation were observed and recorded.

Primary Outcome Measures

Name	Time	Method
One-time success rate of intubation	through study completion,an average of 1 minute
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
Glottic field grading	through study completion,an average of 1 minute	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
