Pragmatic Randomized Trial of Corticosteroids and Inhaled Epinephrine for Bronchiolitis in Children in Intensive Care.

Abstract

OBJECTIVE:

To determine whether the combination of systemic corticosteroids and nebulized epinephrine, compared with standard care, reduces the duration of positive pressure support in children with bronchiolitis admitted to intensive care.

STUDY DESIGN:

We performed a pragmatic, multicenter, open-label, randomized trial between July 2013 and November 2019 in children younger than 18 months old with a clinical diagnosis of bronchiolitis. The intervention group received the equivalent of 13 mg/kg prednisolone over 3 days, then 1 mg/kg daily for 3 days, plus 0.05 mL/kg of nebulized 1% epinephrine made up to 6 ml with 0.9% saline via jet nebulizer and mask using oxygen at 12 l/min every 30 minutes for 5 doses, then 1-4 hourly for 3 days, then as required for 3 days. The primary outcome was clinician-managed duration of positive pressure support in intensive care defined as high-flow nasal-prong oxygen, nasopharyngeal continuous positive airway pressure, or mechanical ventilation.

RESULTS:

In total, 210 children received positive pressure support. In the corticosteroid-epinephrine group, 107 children received positive pressure support for a geometric mean of 26 (95% CI, 22-32) hours compared with 40 (95% CI 34-47) hours in 103 controls, adjusted ratio 0.66 (95% CI 0.51-0.84), P = .001. In the intervention group, 41 (38%) children experienced at least 1 adverse event, compared with 39 (38%) in the control group.

CONCLUSIONS:

In children with severe bronchiolitis, the duration of clinician-managed pressure support was reduced by regular treatment with systemic corticosteroids and inhaled epinephrine compared with standard care.
