  • treatment failure [ Time Frame: 30min after 2nd epinephrine nebulizer ]
    after additional nebulized epineprhine at 30 minutes, as the croup scrore is higher than baselin, the blinding is cleared.

The Effect and Safety of Low Dose Nebulized Epinephrine in Croup
The Effect and Safety of Low Dose Nebulized Epinephrine in the Treatment of Croup

Croup is common illness presenting emergency department with dyspnea. The main treatment for croup is nebulized L-epinephrine and steroid. The study for the dose of nebulized L-epinephrine is restricted that the study of comparision between racemic epinephrine and L-epinephrine.

The investigators conducted this study to compare the effectiveness of low dose L-epinephrine with conventional dose L-epinephrine.
