Recall and Perceived Usefulness of Ganzouri vs LEMON for Airway Checks
Official title: Comparison of Recall and Perceived Applicability of Ganzouri Airway Scoring System Versus LEMON Score for Airway Assessment Among Anesthesia Residents; a Prospective Observational Study
Run by Cairo University · NCT07841392 · Data updated 2026-11-12
We’re testing whether anesthesia residents recall and feel Ganzouri’s airway scoring or LEMON is more applicable for predicting difficult airways.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are first-year anesthesia residents at Kasr Al-Ainy Hospitals with no formal training in either airway scoring system and who consent to participate.
✕Probably not a fit
Residents with prior extensive training in either scoring system or those not participating will not contribute to the comparative recall or perceived applicability data.

What this trial studies
This observational study compares how well first-year anesthesia residents remember and rate the practicality of two airway assessment tools, Ganzouri and LEMON, after exposure to none of them previously. It aims to see which scoring system residents find more useful in real clinical settings for airway planning. The trial involves residents at Kasr Al-Ainy Hospitals and follows them from baseline through a two-week follow-up. The focus is on recall and perceived applicability, not on patient outcomes. The findings could help inform education on airway assessment in training programs.
Why it matters
Potential benefit: If one scoring system is favored, training programs can tailor curricula to improve airway assessment skills.
How similar studies have gone: Similar comparative assessments of airway scoring tools have shown varying levels of recall and perceived utility, making this a novel application in this specific learner population.
