Lesson B Overview • Bites and Stings • Anaphylaxis • Angioedema Boone County Fire Protec/on District EMS Educa/on

Bites & Stings • Venom issue • Some only local to the site • Some systemic • Anaphylaxis risk potential Boone County Fire Protec/on District EMS Educa/on

Bite / Sting Care • Remove stinger or tentacles by scraping • Standard wound care • Ice is good • No tourniquets • Jellyfish specific—use vinegar then shower Boone County Fire Protec/on District EMS Educa/on

Anaphylaxis • Can include upper airway swelling Stridor or difficulty swallowing • Racemic epinephrine shrinks swollen tissue • • Can include lower airway (wheezing) • Can include distributive shock • Epi breaks the reaction chain—and treats the symptoms (massive histamine release) Boone County Fire Protec/on District EMS Educa/on

Angioedema • NOT an anaphylactic reaction but can occur alongside anaphylaxis. • Can be very dramatic in appearance • Can be life threatening if upper airway obstructs (assess for stridor) • Usually self-limiting and resolves without treatment • Treat anaphylaxis with Epi—whether or not angioedema is also present Boone County Fire Protec/on District EMS Educa/on

Beta Blockers • Beta blockers are prescribed to treat tachy dysrhythmia or hypertension. Therefore, some patients who are experiencing an anaphylactic reaction will be taking beta blockers. • Glucagon will reverse the beta blockade and allow epinephrine to work as anticipated.

Lesson B Main Points • Bites and Stings are typically painful but not a big deal unless they cause anaphylaxis. Scrape the stinger off, use ice and general wound care. • Anaphylaxis is best treated with Epi to break the chain reaction and to treat the symptoms. • Angioedema is usually no big deal on its own but commonly occurs with anaphylaxis. • Airway obstruction from swelling is the killer.
