Pre-school wheeze is really common, with evidence suggesting that 50% of children will have at least one episode of acute wheeze by the age of 6years. 

Over the last 10-15years, there have been a number of studies looking at the use of steroid therapy in this group.

At this time, whilst we recognise that there are a group of children that will benefit from steroid therapy, the evidence remains unclear as to which children presenting to the ED should be prescribed them.
