Introduction:

• ü  Acquisition of skills in airway videoscopy is crucial for anesthesiology training.
• ü  Video laryngoscopy and flexible videoscopy are essential skills.
• ü  Retrograde transillumination may aid in better visualization of airway structures

Methods:

• ü  A randomized controlled trial involving 92 surgical patients.
• ü Randomized into two groups: Group C (Conventional videoscopy) and Group R (Retrograde transillumination-assisted videoscopy).
• ü  Anaesthesia residents were trained to perform flexible videoscopy.
• ü  Retrograde transillumination was achieved using an OTICA LED vein finder

Results:

• ü  Time to visualize the glottis (T1) and time to see the tracheal rings (T2) were comparable between the two groups.
• ü  61% of residents found retrograde transillumination very helpful.
• ü  No incidence of desaturation was noted in either group.

Conclusion:

• Retrograde transillumination-assisted flexible videoscopy aids in identifying the glottis and makes the procedure more manageable for learners.
