Three-Part Question:
In a [child with croup] is [nebulised epinephrine or nebulised budesonide] more effective at [reducing croup score and length of stay]?
Clinical Scenario:
A 4 year old girl attends the emergency department with moderately severe croup. You have heard that croup responds to steroid therapy, but wonder whether it is more effective than nebulised epinephrine.

Nebulized budesonide is as effective as nebulized adrenaline in moderately severe croup. Fitzgerald D, Mellis C, Johnson M et al. 1996, Australia 66 hospitalised children with viral or spasmodic croup.
Budesonide 2mg vs epinephrine 4mg
PRCT Duration of croup attack in hours 31[21] vs 26[21] (not significant) Sample size calculated to be 66 but only 53 completed the 24 hr study.
No follow up
Change in total croup symptom score 7.1[1.2] vs 7.7[1.1] (not significant)
Side effects No significant difference
Author Commentary:
This study shows that there are no significant clinical differences between the two treatments. In such a case the relative cost of the treatment is an important factor in deciding which should be prescribed.

[Web Editor comments] The small size of this study means that no conclusion can be drawn regarding the difference between these treatments.
Bottom Line:
Nebulized epinephrine and nebulized budesonide are as effective as each other in moderately severe croup.
Level of Evidence:
Level 3: Small numbers of small studies or great heterogeneity or very different population
