  Purpose

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.

Primary Outcome Measures:
  • the difference of Westley croup score between baseline and 30 minutes after neublized treatment [ Time Frame: 30 minutes ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • the incidence of use of additional neublized treatment [ Time Frame: 30 minutes ] [ Designated as safety issue: Yes ]
  • Westley croup score [ Time Frame: 30, 60, 90, 120, 180, 240 minutes ] [ Designated as safety issue: Yes ]
  • the side effect of epinephrine [ Time Frame: participants will be followed for the duration of ED stay ] [ Designated as safety issue: Yes ]
    Hypertension, tachycardia : more than 95th percentile for age Arrythmia Pallor Tremor

  • respiratory rate, oxygen saturation [ Time Frame: 30, 60, 90, 120, 180, 240 minutes ] [ Designated as safety issue: Yes ]
  • health care utilization- length of stay in emergency department, admission rate, revisit dut to croup symptom [ Time Frame: within 7 days ] [ Designated as safety issue: Yes ]
  • treatment failure [ Time Frame: 30min after 2nd epinephrine nebulizer ] [ Designated as safety issue: Yes ]
    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 ] [ Designated as safety issue: Yes ]
    the croup score is the same or over than the base line
