A child in anaphylactic shock: which management statement is true?

• A. May require a low-dose epinephrine infusion
• B. Epinephrine is never used in children
• C. Antihistamines alone are sufficient
• D. Steroids alone suffice

Answer: (A)

Prompt recognition of anaphylaxis hinges on rapid reversal of airway swelling, bronchospasm, and hypotension. Epinephrine is the key treatment because it acts on multiple receptors to tighten blood vessels (alpha1), strengthen the heart's pumping (beta1), and open airways (beta2). In most pediatric cases, an intramuscular dose of epinephrine promptly improves symptoms. However, if the child remains unstable or symptoms persist after the initial dose, a continuous low-dose epinephrine infusion may be needed in a monitored setting to maintain blood pressure and airway patency while monitoring for side effects.

Epinephrine is not never used in children—quite the opposite, it is the first-line therapy. Antihistamines and steroids, while they may play adjunct roles, do not treat the acute life-threatening aspects of anaphylaxis on their own and should not replace epinephrine. Steroids may help with potential biphasic reactions, and antihistamines can address some symptoms, but neither reverses airway compromise or shock quickly enough in the emergency setting.
