What is the first-line treatment for anaphylaxis with airway compromise but no cutaneous symptoms?

• A. Oral antihistamines only.
• B. Bronchodilator inhaler only.
• C. Keep patient in place and observe.
• D. Epinephrine administration, oxygen, rapid transport.

Answer: (D)

In anaphylaxis, especially when the airway is threatened, the immediate priority is to reverse the underlying reaction. Epinephrine is the first-line treatment because it works across the main problem areas at once: it tightens blood vessels to reduce airway and systemic edema, raises blood pressure to prevent shock, and relaxes airway smooth muscle to relieve bronchospasm. It also helps stabilize the reaction by dampening further mediator release from mast cells. Even if there are no skin signs, the risk to the airway can be life-threatening, so epinephrine is given right away. Following that, provide oxygen to optimize breathing and ensure adequate oxygen saturation, and arrange rapid transport so the patient can receive advanced care if needed. The other options don’t address all the critical issues quickly enough: antihistamines don’t rapidly relieve airway obstruction or hypotension; a bronchodilator helps with bronchospasm but not the swelling or blood pressure; and simply observing leaves the patient at ongoing risk.
