Westley Croup Score

Classifies croup severity to guide management (dexamethasone, nebulised adrenaline, PICU).

Score interpretation

Mild Croup 0–2

Westley Score 0–2: Mild croup. Barky cough, no stridor at rest.

→ Oral/IM dexamethasone 0.15 mg/kg (max 10 mg). Reassure family. Discharge home if improving.

Moderate Croup 3–5

Westley Score 3–5: Moderate croup. Stridor at rest, mild to moderate retractions.

→ Dexamethasone 0.15 mg/kg. Consider nebulised L-adrenaline (1:1000, 0.5 ml/kg max 5 ml). Monitor 1–2 hours. Admit if no improvement.

Severe Croup 6–8

Westley Score 6–8: Severe croup. Significant respiratory distress.

→ Senior paediatric review. IV/IM dexamethasone. Nebulised L-adrenaline. High-flow O₂. Consider PICU transfer.

Impending Respiratory Failure 9–17

Westley Score ≥9: Impending respiratory failure. Cyanosis or altered consciousness.

→ CALL ANAESTHETIST + PICU NOW. O₂. Nebulised adrenaline. Prepare for emergency intubation. Minimise distress — keep child with parent.
