Comparing two ways to place a double-lumen breathing tube: bronchoscope plus video laryngoscope versus video laryngoscope alone
Official title: Effect of Combined Use of Flexible Bronchoscope on First-attempt Sucess in Tracheal Double Lumen Tube Intubation Using Videolaryngosocpe: A Randomized Controlled Trial
Run by Kyung Hee University Hospital at Gangdong · NCT07241208 · Data updated 2026-11-12
We will test whether adding a flexible bronchoscope to a video laryngoscope helps doctors place double-lumen breathing tubes on the first try for people having thoracic (one-lung) surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults scheduled for thoracic surgery who need a double-lumen tube for one-lung ventilation, have ASA physical status I–III, BMI between 18.5 and 35, and no prior airway surgery or obstructing pathology.
✕Probably not a fit
Patients with very low or very high BMI, prior airway surgery, suspected high aspiration risk, or tumors/inflammation of the oropharynx or larynx are excluded and likely would not benefit from this protocol.

What this trial studies
This interventional study compares first-attempt success of double-lumen tube insertion using video laryngoscopy alone versus video laryngoscopy combined with flexible bronchoscopy guidance. Patients scheduled for thoracic surgery who require one-lung ventilation and meet inclusion criteria are assigned to one of the two intubation approaches. The primary outcome is first-pass intubation success, with other measures likely including intubation time, airway trauma, and need for additional attempts or adjuncts. All procedures are performed in the operating room at a single center by anesthesiologists familiar with both devices.
Why it matters
Potential benefit: If successful, the approach could increase first-pass intubation success, lowering airway trauma and complications during thoracic surgery.
How similar studies have gone: Bronchoscopic guidance is commonly used to confirm or guide double-lumen tube placement, but randomized comparisons specifically of first-attempt success versus video laryngoscope alone are limited.
