It may not be her fault. As of the time I write this post in late 2017, the national EMT standards for anaphylaxis are only to administer epinephrine ONLY if bronchospasm and hypotension present. These are the offline protocols from our regional medical director. We are trained that full body hives, GI distress, and dizziness are not signs (observed) or symptoms (reported by patient) of anaphylaxis. The rest is assumed to be attributed to patient anxiety or simple hives regardless of history. Our textbook, which is considered the gold standard, makes no mention of mast cells, etc., only the release of histamines.
The bottom line here is making administration of epinephrine possible for BLS (EMT-B) has not transferred successfully in concert with recognition of anaphylaxis as allergists and all major allergy and anaphylaxis organizations have defined for years. Short 'N Sweet version: EMS are trained to administer only if wheezing and blood pressure drop present. We otherwise are trained to consider it anxiety or benadryl the appropriate drug for histamine.
