• primarily clinical
• AP neck radiograph presenting with steeple sign
• CBC and other basic shit

Question 7

Croup treatment (mild and significant (3))

Answer 7

• Mild can be done at home with management
• significant respiratory distress will require oxygenation with ventilatory support (bag ventilation mask but potentially intubation (rare less than 2%)), single dose dexamethasone .6mg/kg oral, IM, or IV, or nebulized racemic epi

Question 8

Bacterial tracheitis

Answer 8

Uncommon cause of upper airway obstruction except in patients with tracheostomy or ET tube that is more common in the pediatric presentation, possible with croup patients that worsen or do not respond to typical treatments, majority require intubation as treatment, high grade fever unlike croup, no response to epi

Answer 10

Acute inflammation caused by bacterial infection typically of epiglottis and surrounding tissues, uncommon in US more common in populations lacking against Haemophilus influenza type B immunization, viruses do not typically cause but can predispose to bacterial infection, sees RAPID* symptom progression, often present with sore throat, dysphagia, hot potato voice, tripoding
