CT-guided DLT sizing for thoracic surgery with one-lung ventilation
Official title: CT-Guided Versus Traditional Selection of Double-Lumen Tube Size for One-Lung Ventilation in Thoracic Surgery: A Prospective Study
Run by King Hussein Cancer Center · NCT07575763 · Data updated 2026-11-12
This trial tests whether using preoperative CT measurements to pick the right double-lumen tube size helps surgeons get the first fitting right in adults having thoracic surgery with one-lung ventilation.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) scheduled for elective thoracic surgery requiring one-lung ventilation with available preoperative thoracic CT imaging and normal pulmonary function.
✕Probably not a fit
Patients without preoperative CT imaging, with difficult airway, emergency procedures, or who fail to meet other exclusion criteria may not benefit.

What this trial studies
This prospective, randomized, single-blinded study compares CT-based bronchial diameter measurements to conventional sizing methods for selecting the initial double-lumen tube in adults undergoing thoracic procedures requiring one-lung ventilation. Participants are randomly assigned to either the CT-guided sizing group or the conventional sizing group in a 1:1 ratio. The aim is to determine if CT guidance increases accuracy of initial DLT size and potentially improves airway management during thoracic anesthesia. The trial relies on preoperative thoracic CT imaging and standard intraoperative procedures with left-sided DLT placement.
Why it matters
Potential benefit: If successful, patients may experience more accurate DLT sizing, potentially reducing intubation attempts and airway-related complications.
How similar studies have gone: Prior approaches using imaging-based airway measurements have shown promise in selecting airway devices, but direct CT-guided DLT sizing for this indication is novel and requires validation.
