Three-part question In [children with croup] is [heliox] effective in [relieving symptoms and reducing croup score]?
CLINICAL SCENARIO
A 2
-year-old girl is brought to the emergency department in respiratory distress. Her father tells you that he noticed a barking cough throughout the night and that her breathing was becoming noisier. On examination the child is alert and tachypnoeic, has got a tracheal tug and recession, an audible inspiratory and expiratory stridor, SpO2 >92%, temperature 38.3°C. You decide that you are going to treat with dexamethasone and wonder whether heliox might be effective as a "bridging therapy" in relieving symptoms and improving the croup score.
