Dosing of Steroids for Acute Asthma Given in the Emergency Department - a Pilot Randomised Feasibility Trial of Dexamethasone in Children

Recruiting now · Phase 4

Conditions studied: Acute Asthma, Dexamethasone

In brief

Steroids given by mouth are an important first line treatment for children presenting with asthma attacks. Dexamethasone is the steroid used in some emergency departments (EDs) because of the need for a single dose and as it is well tolerated. The dose of dexamethasone in treating asthma attacks is not clearly established. This study compares two different doses of dexamethasone in children presenting with an asthma attack. Investigators will compare the effect of two different doses in reducing the need for a repeat prescription of steroids for an asthma attack in the 2 weeks after the first treatment. The investigators will also look at how often children attend the ED or their GP after being given treatment as well as the acceptability to parents and children. Although this study may provide an answer to the question of whether the different doses have the same effect, the investigators believe that a larger study will be needed to provide robust generalisable evidence, as well as to ensure that the outcomes are truly what matters to parents, children and healthcare professionals. This study will provide valuable information to enable a larger study to be undertaken.
