A 4 year old girl attends the paediatric assessment unit with a 2 day history of a sore throat. Her father says her oral intake has been reducing and she has been refusing all food and drink for the last 6 hours. On initial assessment, she is sitting forward on out stretched arms, she is drooling, and there is audible stridor.
Based on the likely diagnosis, which is the least appropriate option to form part of her management plan?
