Various intravenous (IV) corticosteroids are available for acute severe asthma (ASA) treatment. The choice of IV corticosteroids varies broadly and depends on institution, country, or physician preferences. In this study, we compared the efficacy of IV methylprednisolone, hydrocortisone and dexamethasone in ASA treatment during pediatric intensive care unit (PICU) admission. The study was a prospective randomized clinical trial. We enrolled patients of 1–21 years after they were admitted to the PICU requiring continuous beta-2 agonist treatment. Patients were randomized into three groups: Group A: IV Methylprednisolone, Group B: IV Hydrocortisone and Group C: IV Dexamethasone. The primary outcomes measured were durations of beta-2 agonist continuous nebulization treatment. Secondary outcomes, included PICU and hospital length of stay (LOS), pediatric asthma severity score (PASS), need for mechanical ventilation and maximum dose of beta-2 agonist treatment. 61 patients were included in the analysis. 22 patients recruited in Group A, 20 in group B and 19 group C. Median durations of beta-2-agonist treatment were 23 h (QR 16–38) for methylprednisolone, 27 h (QR 16–40) for hydrocortisone, and 32 h (QR 16–48) for dexamethasone ( p  = 0.90). There was no difference in PICU LOS, hospital LOS, PASS score, B2 agonist maximum dose, or need for ventilation support. The use of IV methylprednisolone, hydrocortisone, and dexamethasone have equivalent efficacy when used at the appropriate doses. Studies with larger cohorts are needed to compare the effectiveness of IV corticosteroids in the management of ASA in the PICU setting.

Methylprednisolone, dexamethasone or hydrocortisone for acute severe pediatric asthma: does it matter?
