University of Louisville
  Purpose
The purpose of this study is to assess whether children with moderate to severe bronchiolitis treated with standard racemic epinephrine therapy via 70:30 helium-oxygen (heliox) driven nebulization will have improvements in measurements of airway more rapidly than those treated with conventional air-oxygen driven nebulization.

Condition Intervention Phase
Bronchiolitis Drug: heliox Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: The Use of Heliox Driven Racemic Epinephrine Nebulization in the Treatment of Moderate to Severe Bronchiolitis in Pediatric Emergency Department Patients

Ages Eligible for Study:   2 Months to 12 Months   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Any child 2-12 months old seen in the emergency department.
  • A clinical bronchiolitis score > 3 by modified Wood's Clinical Bronchiolitis Score (M-WCBS).
  • Diagnostic criteria of bronchiolitis includes tachypnea, cough, prolonged expiratory phase, wheezing, rales, chest retractions, and hyperinflation of lungs on chest radiograph. After consenting a patient to the study, respiratory syncytial virus (RSV) infection will be tested by rapid enzyme-linked immunoabsorbent assay of nasal secretions.

Exclusion Criteria:

  • No child will be excluded based on race or gender
  • Patients under the age of 2 months or greater than 12 months
  • Patients with cyanotic heart disease
  • Patients with lobar pneumonia, defined by results of chest radiographs.
  • The presence of interstitial disease or diffuse patchy marking consistent with atelectasis on chest radiographs will not exclude patients.
  • Patients with croup.
  • Patients with foreign body aspiration.
  • Patients with history of cystic fibrosis, bronchopulmonary dysplasia or other chronic lung disease.
  • Patients with liver or renal disease.
  • Patients with sickle cell anemia.
  • Patients requiring mechanical ventilation.
  • Patients who develop supraventricular tachycardia secondary to racemic epinephrine administration.
  • Patients with tracheomalacia or bronchomalacia.
  • Patients who had received bronchodilators within 2 hours of initiation of the study.
  • Patients who had received systemic corticosteroids within 72 hours of enrollment
  • Patients who suffered from persistent airway hyperreactivity in the 3 months before the study.
  • Patients who do not tolerate the nasal cannulae for 45 out of 60 minutes.
