Infrared flashing light through the cricothyroid membrane as guidance to awake intubation with a flexible bronchoscope: A randomised cross‐over study
Authors' conclusion
During awake intubation of patients with airway pathology, the application of trans-cricothyroid infrared flashing light to guide the insertion of a flexible bronchoscope significantly facilitated the recognition of the pathway into the trachea and the correct advancement of the flexible endoscope.
Study context
- Population
- Patients with severe airway pathology undergoing awake intubation with a flexible bronchoscope44 insertions

- Comparison
- Infrared vs Conventional
- Primary endpoint
- Anatomical landmark at which the correct pathway to the trachea was identified (video recorded)
Methodological detailscross-over, random order, All insertions video recorded
- Cross-over
- Random order
- All insertions video recorded
