Comparing awake tracheal intubation through the mouth versus the nose.
Official title: Patient Experience of Transoral Versus Transnasal Awake Tracheal Intubation With Flexible Bronchoscopy - an Observational Study
Run by Universitätsklinikum Hamburg-Eppendorf · NCT06955884 · Data updated 2026-11-12
This study will test whether awake tracheal intubation through the mouth or the nose causes less discomfort for adults who need flexible bronchoscopy-guided intubation for a difficult airway.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) scheduled for surgery with an anticipated difficult airway who are planned to receive awake flexible bronchoscopy-guided tracheal intubation and can provide informed consent are ideal candidates.
✕Probably not a fit
People who do not require awake bronchoscopy-guided intubation, pregnant or breastfeeding patients, minors, or those unable to give consent are unlikely to benefit from joining this observational comparison.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is an observational comparison of two routes for awake tracheal intubation using flexible bronchoscopy with preserved spontaneous breathing (ATI:FB). Adults with an anticipated difficult airway who are scheduled for surgery and consent to ATI:FB will undergo either a transnasal or transoral approach as used by their clinical team. The study will collect patient-reported discomfort and tolerance measures plus operator-focused metrics such as procedure time, ease of tube passage, and immediate complications. Data will be analyzed to compare patient-centred and operator-centred outcomes between the two routes.
Why it matters
Potential benefit: If successful, the results could help clinicians choose the intubation route that reduces patient discomfort and improves tolerance and procedural efficiency during awake bronchoscopy-guided intubation.
How similar studies have gone: Awake bronchoscopy-guided intubation is an established technique, but direct head-to-head data comparing patient discomfort between transnasal and transoral routes are limited.
