Corticosteroids in status asthmaticus.

Nineteen children who were not steroid dependent and were hospitalized in status asthmaticus were studied to evaluate the effect of corticosteroids. They were randomized into two groups. Each group received salbutamol inhalations and intravenous aminophylline therapy. One group received 7 mg/kg hydrocortisone intravenously every six hours; the other group served as a control. Each group showed significant improvement in clinical score and peak expiratory flow rate after 36 hours; there was no statistical difference in the degree of improvement. Six of ten steroid-treated children and six of nine controls achieved a PEFR of 50% predicted by 36 hours. The response to inhaled salbutamol was similar in each group. The results show that in the first 36 hours of therapy, corticosteroids have no additive effect on the bronchodilator response of aminophylline and salbutamol and do not hasten the recovery of nonsteroid-dependent children in status asthmaticus. Although the results show that an inhaled sympathomimetic drug is beneficial in status asthmaticus, corticosteroid therapy does not increase the responsiveness of the airways to these agents.
