😮 El-Ganzouri Risk Index (Difficult Airway)
UseWhen to use: pre-intubation airway risk stratification (OR/ED/ICU).
Strata≥4 elevated difficult-intubation risk — plan VL/awake options.
LimitsWhen not to use: as proof of easy airway if <4. · Pitfall: ignoring other red flags (LEMON, neck pathology). · Have failed-airway plan regardless.

When to use
When to use: pre-intubation airway risk stratification (OR/ED/ICU).
How it works
Mouth, TMD, Mallampati, neck ROM, prognath, weight, difficult-intubation history (max 12).
Key points
- 0–12.
- ≥4 high-risk cue.
- Next: ASA DA algorithm / VL.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Mouth opening | ≥4 cm (0) |
|---|---|
| Thyromental distance | 6.0–6.5 cm (+1) |
| Mallampati class | II (+1) |
| Neck movement | 80–90° (+1) |
| Ability to prognath (jaw thrust forward) | Yes (0) |
| Body weight | 90–110 kg (+1) |
| History of difficult intubation | Questionable (+1) |
→EGRI5/12
- Cue：≥4 — elevated difficult-intubation risk; plan VL/awake options
| Mouth opening | ≥4 cm (0) |
|---|---|
| Thyromental distance | >6.5 cm (0) |
| Mallampati class | I (0) |
| Neck movement | >90° (0) |
| Ability to prognath (jaw thrust forward) | Yes (0) |
| Body weight | <90 kg (0) |
| History of difficult intubation | None (0) |
→EGRI0/12
- Cue：<4 — lower EGRI band; still prepare failed-airway plan

FAQ
Frequently asked questions
- Does El-Ganzouri Risk Index (Difficult Airway) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is El-Ganzouri Risk Index (Difficult Airway) calculated in practice? Can you show a worked example?
- Inputs: Mouth opening ≥4 cm (0), Thyromental distance 6.0–6.5 cm (+1), Mallampati class II (+1), Neck movement 80–90° (+1), Ability to prognath (jaw thrust forward) Yes (0), Body weight 90–110 kg (+1), History of difficult intubation Questionable (+1) → Result: EGRI 5 /12（Cue: ≥4 — elevated difficult-intubation risk; plan VL/awake options） Inputs: Mouth opening ≥4 cm (0), Thyromental distance >6.5 cm (0), Mallampati class I (0), Neck movement >90° (0), Ability to prognath (jaw thrust forward) Yes (0), Body weight <90 kg (0), History of difficult intubation None (0) → Result: EGRI 0 /12（Cue: <4 — lower EGRI band; still prepare failed-airway plan）
