Comparison of Double-lumen Tube Intubation Between Fiberoptic Bronchoscopy and Video Laryngoscope
The goal of this clinical trial is to compare the first-attempt success rate in double-lumen tube intubation. The main question it aims to answer:
Is there any difference in the first-attempt success rate of intubation between using flexible bronchoscopy and a video laryngoscope? Researchers will compare the group using a flexible bronchoscope and video laryngoscope with the group using a video laryngoscope only to see if there is a difference in first-attempt success rate.
Participants will be intubated in one of two interventions.

About this study
For double-lumen tube insertion, a video laryngoscope can usually be used. However, because the camera is located at the tip, there can be a difference between the line of sight and the actual glottic view, which may make double-lumen tube steering difficult.
Flexible bronchoscopy can guide the double-tube along the natural curvature of the airway with less trauma. In the present research, we hypothesized that the first-pass success rate may differ between a group using video laryngoscopy only and a group using video laryngoscopy and flexible bronchoscopy.
