Study Notes
Croup Diagnosis and Management
- Diagnosis of croup is based on clinical findings of barking cough, inspiratory stridor, and hoarseness.
- Diagnostic testing is typically not necessary, and the absence of fever does not rule out croup.
- Respiratory rate is often increased in patients with croup.
Croup Treatment
- Corticosteroids should be administered to patients with croup of any severity.
- Epinephrine should be administered to patients with moderate to severe croup.
- Humidified air inhalation does not improve symptoms in patients with moderate croup.
- Oxygen should be administered to children with hypoxemia or severe respiratory distress.
Westley Croup Score
- The Westley Croup Score is used to assess the severity of croup.
- The score is based on clinical signs such as level of consciousness, stridor, air entry, and retractions.
- A score of ≤2 indicates mild croup, 3-7 indicates moderate croup, and ≥12 indicates impending respiratory failure.
Outpatient Management
- Minimizing agitation in a symptomatic child can help improve symptoms.
- Placing the child in a comfortable position may help improve the evaluation and treatment process.
- Dexamethasone is the preferred corticosteroid due to its single-dose administration and ability to be given orally, intramuscularly, or intravenously.
- The optimal dose of dexamethasone is unclear, but 0.6 mg per kg is the most commonly used.
Use of Epinephrine
- Epinephrine is thought to improve symptoms in patients with croup through arteriole vasoconstriction in the upper airway mucosa.
- The effects of epinephrine wane after one to two hours, so patients should be monitored for at least two hours after administration.
- Adverse effects of nebulized epinephrine are rare, but patients receiving frequent treatments should be monitored for adverse cardiac effects.
This quiz covers the diagnosis and management of croup, a common childhood illness characterized by cough, inspiratory stridor, and hoarseness.
