• 1 other identifier: MS-225-2026 (1-7-2026)
• Study Type: observational
• Target: 44
• Locations: 1 country

Brief Summary

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.

Conditions

Recall; Perceived Applicability; Ganzouri Airway Scoring System; LEMON Score; Airway; Anesthesia Residents

Outcome Measures

Primary Outcomes (1)

• 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.

  Within 30 minutes after completion of the educational lectures

Secondary Outcomes (2)

• Mean total delayed recall score at Day 14

  14 days after completion of the educational lectures

• Resident satisfaction

  14 days after completion of the educational lectures

Study Arms (1)

Study group

First-year residents who didn't receive training in Ganzouri or LEMON Airway scoring systems.

Other: Ganzouri Airway Scoring System; Other: LEMON Score

Interventions

Ganzouri Airway Scoring System OTHER

This scoring system evaluates seven parameters: 1. Mouth opening (interincisor distance) 2. Thyromental distance 3. Mallampati classification 4. Neck movement 5. Ability to prognath (mandibular protrusion) 6. Body weight 7. History of difficult intubation Each parameter was scored, score interpretation from 1- 4 with increasing difficulty , ≥4 suggesting awake intubation.

Study group

LEMON Score OTHER

The LEMON mnemonic represents: 1. Look externally (facial trauma, large incisors, beard, etc.) 2. Evaluate 3-3-2 rule (mouth opening, hyomental distance, thyroidtomouth distance) 3. Mallampati score 4. Obstruction (presence of airway obstruction) 5. Neck mobility
