Clinical Trial: The Effect and Safety of Low Dose Nebulized Epinephrine in Croup
Study Status: Completed
Recruit Status: Unknown status
Study Type: Interventional
Official Title: The Effect and Safety of Low Dose Nebulized Epinephrine in the Treatment of Croup
Brief Summary:
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.
Detailed Summary:
Sponsor: Seoul National University Hospital
Current Primary Outcome: the difference of Westley croup score between baseline and 30 minutes after neublized treatment [ Time Frame: 30 minutes ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- the incidence of use of additional neublized treatment [ Time Frame: 30 minutes ]
- Westley croup score [ Time Frame: 30, 60, 90, 120, 180, 240 minutes ]
- the side effect of epinephrine [ Time Frame: participants will be followed for the duration of ED stay ]Hypertension, tachycardia : more than 95th percentile for age Arrythmia Pallor Tremor
- 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
Original Secondary Outcome: Same as current
