Comparison of Double-lumen Tube Intubation Between Fiberoptic Bronchoscopy and Video Laryngoscope

December 20, 2025 updated by: Hyungseok Seo, Kyung Hee University Hospital at Gangdong

Effect of Combined Use of Flexible Bronchoscope on First-attempt Sucess in Tracheal Double Lumen Tube Intubation Using Videolaryngosocpe: A Randomized Controlled Trial

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.

Detailed Description

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.
