Outpatient—Emergency Department (Injury and Poisoning) Patient Name: William Barrett Diagnosis: Anaphylaxis A 24-year-old male arrived at the emergency department (ED) via ambulance. He had been playing a round of golf at the local golf course when just after teeing off on the third hole, he slapped his shoulder exclaiming that he had just been stung by a hornet. He immediately experienced generalized pruritus, urticaria, angioedema, and nausea. His golf partner, who was knowledgeable about reactions from stinging insects, pulled out his cell phone and called 911. The ambulance crew arrived within a few minutes, administered epinephrine, and transported him to the ED. In the ED, the emergency physician performed a level 3 E/M service and explained to the patient that his diagnosis of anaphylaxis was a reaction to a hornet sting. The physician then ordered another intramuscular injection of epinephrine (0.1 mg). Once the patient’s symptoms resolved, he was discharged with an oral antihistamine to be taken for 24 hours and a kit containing a prefilled syringe of epinephrine and an epinephrine nebulizer for prompt self-treatment for any future reaction. He was advised to see a physician for evaluation of venom immunotherapy (desensitization).
