Is this trial a fit for you?
✓Likely a good fit
Adults 18–75 undergoing elective VATS thoracic surgery requiring a double-lumen tube, with accessible preoperative chest CT and ASA I–III.
✕Probably not a fit
Patients with severe preexisting respiratory disease, difficult airways, or airway/anatomy abnormalities may not benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This interventional trial uses preoperative 3D airway reconstruction to tailor the selection of double-lumen tubes for patients undergoing elective VATS thoracic procedures. By linking patient-specific airway anatomy from chest CT to tube sizing, the approach aims to reduce intubation failures and perioperative adverse events. The study compares 3D-guided, gender- and height-based tube selection to standard methods. Eligible adults aged 18–75 with ASA I–III and available preoperative CT are enrolled at Peking Union Medical College Hospital. Outcomes focused on airway management accuracy and safety during anesthesia are inferred from the protocol.
Why it matters
Potential benefit: If successful, patients may experience more reliable airway management and fewer intubation-related complications during lung surgery.
How similar studies have gone: Previous work in airway planning and individualized tube sizing has shown promise, but this approach applying 3D reconstruction for DLT selection is relatively novel in this context.
