  • the incidence of use of additional neublized treatment [ Time Frame: 30 minutes ]
  • Westley croup score [ Time Frame: 30, 60, 90, 120, 180, 240 minutes ]

  • respiratory rate, oxygen saturation [ Time Frame: 30, 60, 90, 120, 180, 240 minutes ]
  • health care utilization- length of stay in emergency department, admission rate, revisit dut to croup symptom [ Time Frame: within 7 days ]
  • 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.
  • rebound effect [ Time Frame: 180 minutes ]
    the croup score is the same or over than the base line

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.
