What is the immediate intervention following the diagnosis of anaphylaxis?

• A. EABCA: Epinephrine, Airway, Breathing, Circulation, Activate EMS
• B. Administer antihistamines first
• C. Elevate legs and wait
• D. Call code blue and do not treat

Answer: (B)

Anaphylaxis must be treated immediately with epinephrine because it quickly reverses the life-threatening changes caused by the reaction. Epinephrine relaxes airway smooth muscle and tightens blood vessels, which helps open the airways, reduce swelling, and raise blood pressure. The fastest, most reliable way to deliver it is an intramuscular injection into the mid-outer thigh. After giving epinephrine, summon emergency medical help right away and begin supportive care for breathing and circulation. If available, provide high-flow oxygen and monitor the patient closely, being prepared for airway management if symptoms worsen. Antihistamines do not reverse airway obstruction or shock quickly enough and should not delay epinephrine administration; they are not a substitute for it. Elevating the legs and waiting is not appropriate because it delays life-saving treatment, and a response that avoids active treatment or delays help is inappropriate. The priority is prompt epinephrine administration with rapid escalation of care to EMS.
