To determine the effect of helium-oxygen inhalation on relieving symptoms and distress in children with croup as measured by the croup score, and to identify areas of uncertainty for future research. ⋯ At present there is no evidence to support the use of helium-oxygen therapy in children with croup. Methodologically well-designed and adequately powered randomised controlled trials are needed to determine whether helium-oxygen inhalation as part of the initial treatment in croup alters outcome.
