Brief summary

1. Double-lumen tube intubation is difficult, compared with single lume tube. 2. McGrath Series 5 videolaryngoscope hase been used in difficult airway management, both in anesthetized and awake patients. 3. But there was little information about McGrath Series 5 videolaryngoscope for double-lumen tube intubation.

Detailed description

In this study, the purpose was to evaluate the success rate and intubation time of McGrath Series 5 videolaryngoscope for double-lumen tube intubation in patients without predictors of difficult intubation.

Interventions

DEVICEvideolaryngoscope

McGrath Series 5 videolaryngoscope is one kind of portable videolaryngoscopes, which has been usde in both unexpected and anticipated difficult intubation.
