Serial number at source N/A
Study hypothesis Bronchiolitis which is the most common lower respiratory tract infection under the age of one. Symptoms can range from mild to severe and include fever, rhinorrhea, cough, and dyspnea.

Compared to nebulized racemic epinephrine in normal saline, patients with acute bronchiolitis in the emergency department treated with nebulized racemic epinephrine in 3% hypertonic saline will have a statistically significant improvement in their Respiratory Assessment Change Score (RACS).
Lay summary

Countries of recruitment Canada
Disease/condition/study domain Bronchiolitis
Participants - inclusion criteria Infants 6 weeks to 12 months of age with clinical symptoms of a viral respiratory infection (coryza or temperature ≥ 38.0°C), first episode of wheezing, oxygen saturation ≥ 85% but ≤ 96%, and initial Respiratory Distress Assessment Instrument (RDAI) score ≥ 4.
Participants - exclusion criteria Pre-existing cardiac or pulmonary disease, previous diagnosis of asthma by a physician, any previous use of bronchodilators, severe disease requiring resuscitation room care, inability to administer medication by nebulizer, inability to obtain informed consent secondary to a language barrier, or no phone access for follow-up.

Patient information material
Target number of participants 46
Interventions Patients who entered the study were randomized to receive either nebulized epinephrine in hypertonic saline or nebulized epinephrine in normal saline. Each patient had his or her oxygen saturation level, heart rate, respiratory rate and Respiratory Distress Assessment Instrument (RDAI) score measured at baseline and then again at 30, 60, 90 and 120 minutes. The nurses, physicians and study team personnel remained blinded throughout the study. There were no invasive procedures involved.
Primary outcome measure(s) The Respiratory Assessment Change Score (RACS) was the primary outcome variable of the study. This score is a clinical scoring system based on the Respiratory Distress Assessment Index (RDAI) and the respiratory rate.
Secondary outcome measure(s) Oxygen saturation and rate of admission to hospital.
