    Glucocorticoids effectively treat croup symptoms in children, reducing hospital stays and readmissions. Oral dexamethasone may be more effective than intramuscular administration for croup management.

    Area of Science:

    • Pediatric Emergency Medicine
    • Pharmacology
    • Systematic Review Methodology

    Background:

    • Croup management has seen continued research into glucocorticoid efficacy.
    • Previous reviews highlighted the need for updated evidence on glucocorticoid treatment for croup.

    Purpose of the Study:

    • To systematically evaluate the effectiveness of glucocorticoids in treating children with croup.
    • To identify evidence gaps for future research in croup management.

    Main Methods:

    • Systematic review of randomized controlled trials (RCTs) identified through comprehensive database searches (CENTRAL, MEDLINE, EMBASE).
    • Inclusion criteria focused on RCTs assessing glucocorticoid treatment objectively in pediatric croup.
    • Data extraction and quality assessment were performed independently by two reviewers with consensus for discrepancies.

    Main Results:

    • Thirty-one RCTs involving 3736 children confirmed glucocorticoid effectiveness in improving croup symptoms (Westley score) within 6-12 hours.
    • Glucocorticoid treatment significantly reduced hospital return visits/readmissions and length of hospital stay.
    • A 10% reduction in epinephrine use was observed in children treated with glucocorticoids; oral dexamethasone showed potential superiority.

    Conclusions:

    • Dexamethasone and budesonide are effective in rapidly relieving croup symptoms and reducing healthcare utilization.
    • Glucocorticoids demonstrate efficacy across mild to moderate croup severity.
    • Further research is needed on disseminating and implementing evidence-based croup practice guidelines.
