- Definitions of croup severity are neither widely accepted nor rigorously derived.
- Oral, inhaled, or intramuscular corticosteroids are recommended for all patients with croup, even with barking cough alone.
- Corticosteroids improve croup scores at 6 hours, reduce re-visits/re-admissions, and reduce ED/Hospital length of stay.
- Consider the Alberta (Canada) Clinical Practice Guideline (see below) or institution-specific (e.g., Children’s Hospital Colorado) algorithms for more clinically relevant guidance of classification and treatment.
Treatment algorithms differ among institutions; for the Alberta Group treatment algorithm.
