Ultrasound versus auscultation and bronchoscopy for checking double-lumen tube placement

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational comparison in adults scheduled for elective thoracic surgery with planned one-lung ventilation using double-lumen endobronchial tubes. After tube placement operators will perform bedside lung ultrasound and standard auscultation, then compare both with fiberoptic bronchoscopy as the reference standard. The study will calculate diagnostic performance measures such as sensitivity, specificity, and predictive values for ultrasound and auscultation. The goal is to see if lung ultrasound can reliably confirm correct DLT position when bronchoscopy is not immediately available.
