What is the role of epinephrine in suspected anaphylaxis on board?

• A. Administer per protocol if available, monitor patient, and summon emergency assistance for further care
• B. Administer only after EMS arrives
• C. Never administer on board
• D. Use only if blood pressure falls

Answer: (A)

The main idea is that epinephrine is the first-line treatment for suspected anaphylaxis, and it should be given promptly in the on-board setting. If the aircraft has an epinephrine product in the medical kit and a protocol to follow, administer it right away when anaphylaxis is suspected. After giving the epinephrine, you must monitor the patient closely—watch the airway, breathing, and circulation, check vitals, and stay with them. Then summon emergency medical support or notify the appropriate medical authority on board so they can continue care and arrange for more help after landing.

Why this is the best approach is that epinephrine acts quickly to reduce airway swelling, relieve bronchospasm, and tighten blood vessels to raise blood pressure, which can prevent rapid deterioration. Waiting for EMS to arrive before treating or delaying treatment until blood pressure falls can allow the reaction to worsen. Administering epinephrine only after a recorded drop in blood pressure misses the window where early intervention provides the best chance of a favorable outcome. On board, timely administration, followed by vigilant monitoring and escalation to emergency services, aligns with best practice for suspected anaphylaxis.
