Comparison of McGrath Series 5 and Airtraq Videolaryngoscope for Double-lumen Tube (DLT) Intubation

April 3, 2017 updated by: Wenlong Yao, Huazhong University of Science and Technology

A Randomised Controlled Trial Comparing of McGrath Series 5 and Airtraq Videolaryngoscope for Double-lumen Tube Intubation in Patients With Low Airway Risk Index Score

Previous study showed that McGrath Series 5 videolaryngoscope is an alternative tool for double-lumen tube intubation. We have compared it with traditional Macintosh laryngoscopefor double-lumen tube intubation. In this study, we will investigate its role in double-lumen tube intubation by comparison with another videolarygoscope.
