Comparing awake tracheal intubation through the mouth versus the nose.

Patient Experience of Transoral Versus Transnasal Awake Tracheal Intubation With Flexible Bronchoscopy - an Observational Study

Observational Universitätsklinikum Hamburg-Eppendorf · NCT06955884

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.

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.

Who should consider this trial

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.

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.

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 performed: Awake bronchoscopy-guided intubation is an established technique, but direct head-to-head data comparing patient discomfort between transnasal and transoral routes are limited.
