About this study
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
Our aim is to compare the recall and perceived clinical applicability of Ganzouri airway scoring system versus LEMON score for airway assessment from residents' perspective.
Read the detailed description
Securing a patent airway stands as one of the most fundamental obligations in anesthetic practice, and the timely recognition of a potentially difficult airway prior to induction is of paramount importance for patient safety.
Two of the most widely recognized examples are the Ganzouri Airway Scoring system and the LEMON score. The Ganzouri Airway scoring system integrates seven distinct clinical parameters; mouth opening, thyromental distance, Mallampati classification, neck range of motion, ability to prognath, body weight, and history of prior difficult intubation, each carrying a weighted numerical value whose sum reflects the probability of encountering a difficult airway.

- Being tested
- Ganzouri Airway Scoring System, LEMON Score
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ganzouri Airway Scoring SystemOther
This scoring system evaluates seven parameters:
- Mouth opening (interincisor distance)
- Thyromental distance
- Mallampati classification
- Neck movement
- Ability to prognath (mandibular protrusion)
- Body weight
- History of difficult intubation Each parameter was scored, score interpretation from 1- 4 with increasing difficulty , ≥4 suggesting awake intubation.
LEMON ScoreOther
The LEMON mnemonic represents:
- Look externally (facial trauma, large incisors, beard, etc.)
- Evaluate 3-3-2 rule (mouth opening, hyomental distance, thyroidtomouth distance)
- Mallampati score
- Obstruction (presence of airway obstruction)
- Neck mobility
| Study group | Role | What they receive |
|---|---|---|
| Study group | First-year residents who didn't receive training in Ganzouri or LEMON Airway scoring systems. Receives: Other: Ganzouri Airway Scoring System; Other: LEMON Score |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean total immediate recall score
The total immediate recall score was assessed using a structured recall checklist within 30 minutes after completion of the educational lectures.
Measured: Within 30 minutes after completion of the educational lectures
Secondary outcomes (2)
Mean total delayed recall score at Day 14
The total delayed recall score will be assessed using the same structured recall checklist 14 days after completion of the educational lectures.
Measured: 14 days after completion of the educational lectures
Resident satisfaction
Residents' satisfaction was assessed using a structured post-lecture questionnaire with five-point Likert-scale responses.
Measured: 14 days after completion of the educational lectures

How can a doctor refer a patient or contact the research team?
Contact Ghada A Sherif, MD (00201006153615, drghadasherif@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean total immediate recall score (time frame: Within 30 minutes after completion of the educational lectures). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
