Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older undergoing elective thoracic surgery needing one-lung ventilation and double-lumen intubation, with ASA I–III and able to consent.
✕Probably not a fit
Patients with ASA IV or higher, emergency cases, or anticipated difficult airway or contraindications to any of the three techniques may not benefit.

What this trial studies
This prospective, randomized, open-label study compares three laryngoscopy approaches for double-lumen endobronchial tube placement in adults undergoing elective thoracic surgery requiring one-lung ventilation. It includes three arms: C-MAC hyperangulated (D-blade) videolaryngoscopy, C-MAC Macintosh blade videolaryngoscopy, and direct Macintosh laryngoscopy. The primary outcome is time from end of mask ventilation to fiberoptic confirmation of correct tube position; secondary outcomes include glottic view quality, intubation difficulty, number of attempts, and need for auxiliary maneuvers. The trial is conducted at Trakya University Hospital and aims to inform best practices for safer, more efficient DLT placement in thoracic anesthesia.
Why it matters
Potential benefit: If successful, the study could identify the fastest and easiest method for DLT placement, potentially reducing airway trauma and anesthesia-related complications.
How similar studies have gone: Previous work suggests varying success with videolaryngoscopy versus direct laryngoscopy for complex intubations; this study provides direct comparison in the DLT context.
