26
When is follow up warranted for pharyngitis
In 24 to 48 hrs if worsening 2-7 days post completion of abx if symptomatic

29
Signs and symptoms of croup
Sudden onset barky cough. Fever. Strider on inspiration. Hoarseness Respiratory distress Usually lost 3 to 7 days. Cough usually resolves in 48 hours.
30
Investigations for croup
Investigations are generally not needed. Can do an AP and lateral neck x-ray. Will show steepling of the subglottic region.
31
Management of croup
Supportive treatment with oral hydration, analgesia with Tylenol or Advil Single oral dose of dexamethasone 0.6 mg per KG up to a maximum of 10 mg. Can consider IM if vomiting or significant respiratory distress  If severe croup, then refer to ED and add Blow by oxygen Nebulized 5ml of 1: 1000 L epinephrine
32
When should admission be considered for croup
If respiratory compromise persists for more than four hours after treatment with corticosteroids Additionally, improvement and then worsening There is stridor at rest If there is sternal wall indrawing If no improvement in severe group or group with impendingrespiratory failure contact peds ICU 
33
Features of mild croup
Occasional barking cough with no strider no drawing no distress no cyanosis
34
Pictures of moderate croup

Features of severe croup
Frequent barky cough, inspiratory, and expiratory, strider, marked retractions, lethargy, no cyanosis. Requires treatment in the ED.
36
Features of impending respiratory failure in croup
No barky, cough, minimal strider, severe or absent retractions, significant lethargy, cyanosis without oxygen. Will require treatment in the ED
