NCT07241208

Brief Summary

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.
