This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Acute management of croup in the emergency department. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Assess stridor at rest, retractions, air entry, fatigue, cyanosis and alternate upper-airway diagnoses.
  • Give corticosteroid for croup and use nebulized epinephrine for moderate or severe disease with observation for recurrence.
  • Avoid agitating the child and escalate impending respiratory failure or an atypical toxic presentation.
  • Severity is judged by stridor at rest, retractions, air entry, cyanosis and fatigue rather than cough loudness.

Practical assessment and management workflow

1
Keep the child calm and assess stridor, work of breathing, oxygenation and mental status.
2
Give corticosteroid for clinically diagnosed croup and nebulized epinephrine for moderate or severe obstruction.
3
Observe after epinephrine long enough to confirm sustained improvement.
4
Discharge with caregiver instructions and reassess atypical or recurrent episodes.

Safety, red flags and urgent escalation

  • Drooling, toxic appearance, tripod posture or poor air entry suggests another airway emergency.
  • Severe fatigue, cyanosis or reduced consciousness requires immediate airway expertise.
  • Avoid upsetting examinations and unnecessary throat inspection in significant upper-airway obstruction.
