Question

A 45-year-old male presents pre-hospital with acute urticaria, lip swelling, and abdominal pain after eating shellfish. He has no wheeze, stridor, or cardiovascular compromise. His SpO2 is 98% and BP is 130/80 mmHg. Per RCUK anaphylaxis criteria, does this presentation meet the threshold for IM adrenaline administration?

Accepted Answer

No - this is an allergic reaction with skin and GI involvement only, without airway, breathing, or circulation compromise; antihistamines and observation are appropriate, with adrenaline reserved if progression occurs

Answer

No - but IV adrenaline should be given as a precaution

Answer

Yes - abdominal symptoms confirm anaphylaxis

Answer

Yes - urticaria alone is sufficient to diagnose anaphylaxis

Answer

Yes - any allergic reaction with angioedema requires immediate IM adrenaline
