Comparison of McGrath and Macintosh Laryngoscope for DLT Intubation

The investigators previous study showed that McGrath Series 5 videolaryngoscope is an alternative tool for double-lumen tube intubation. But it is not determined about the advantages and disadvantages of McGrath Series 5 videolaryngoscope for double-lumen tube intubation, compared with traditional Macintosh laryngoscope.
