Q

What are the imagining findings of epiglottis

A

a lateral view in acute epiglottis will show swelling of the epiglottis - the ‘thumb sign’
in contrast, a posterior-anterior view in croup will show subglottic narrowing, commonly called the ‘steeple sign’

Q

Management of epiglottis

A

immediate senior involvement, including those able to provide emergency airway support (e.g. anaesthetics, ENT)
* endotracheal intubation may be necessary to protect the airway

DO NOT examine the throat due to the risk of acute airway obstruction

  • oxygen
  • intravenous antibiotics
