A 3-year-old girl with a known peanut allergy May 31, 2019

A 3-year-old girl with a known peanut allergy arrives to your ED via EMS. The girl was given a cookie by a classmate and immediately developed a generalized urticarial rash. EMS personnel gave her 12.5 mg of oral diphenhydramine and transported her to the ED. On examination, the patient has a heart rate of 160 beats/min with normal oxygenation and perfusion. She has bilateral periorbital swelling, without respiratory distress, wheezing, vomiting, or diarrhea. The accompanying daycare teacher tells you that the girl has previously been admitted to the intensive care unit for anaphylaxis.
You call the girl’s parents for more information and wonder what to do in the meantime. Is diphenhydramine sufficient treatment for this patient? Are corticosteroids indicated? Is this just an allergic reaction or could it be an anaphylactic reaction? What are the criteria for diagnosis of anaphylaxis? What are the indications for administering epinephrine in patients with anaphylaxis?
The parents of the 3-year-old girl stated that the girl’s previous anaphylactic reaction began with urticaria and facial swelling that progressed, resulting in a critical care admission for airway compromise due to angioedema. You administered epinephrine 0.01 mg/kg IM for suspected anaphylaxis and observed the patient in the ED for 4 hours. The girl had complete resolution of the facial swelling and urticarial rash. You reviewed the signs and symptoms of anaphylaxis with the parents, discussed allergen avoidance, and demonstrated appropriate use of an epinephrine autoinjector. You discharged the patient with a prescription for 2 epinephrine autoinjectors and an anaphylaxis action plan.
