What is a common ED management sequence for a child with acute asthma exacerbation?

• A. Observation only.
• B. Oxygen to maintain SpO2, albuterol via spacer or nebulizer, consider ipratropium for more severe, systemic corticosteroids, escalates if poor response.
• C. Antibiotics first.
• D. Intubate immediately.

Answer: (B)

Rapid bronchodilation, good oxygenation, and anti-inflammatory treatment are the core actions in the ED for a child with an acute asthma flare. Start with supplemental oxygen to keep SpO2 in a safe range (typically at least 92–94%, higher in more severe cases). Give a short-acting beta-agonist inhaled through a spacer (or nebulized if coordination or age makes a spacer difficult) to relieve bronchospasm. In more severe situations, add ipratropium bromide to enhance bronchodilation. Administer systemic corticosteroids (oral or IV) to reduce airway inflammation and improve outcomes, even if the child improves with bronchodilators. If the response to initial therapy is poor, escalate: repeat or more frequent bronchodilator dosing, consider magnesium sulfate if still symptomatic, and be prepared to escalate to noninvasive ventilation or, if needed, intubation. Antibiotics are not routinely used in a typical asthma exacerbation unless there is another infection present, and observation alone does not treat the active bronchospasm. Intubation is not the first step and is reserved for life-threatening fatigue, failure to maintain ventilation, or impending respiratory arrest despite treatment.
