FOOD ALLERGY (PEDIATRIC)
Food allergy is an adverse reaction due to a specific immune response occurring reproducibly upon exposure to certain foods. It occurs minutes to hours after food consumption.
Immunological mechanisms can be IgE mediated, non-IgE mediated or mixed IgE and non-IgE mediated.
It may be life-threatening and is the most common cause of anaphylaxis in children.
It should be differentiated from food intolerance in which adverse reactions from exposure to food arise from non-immunological mechanisms.

Supportive Therapy for Acute Life-threatening Allergic Reactions

  • Supplemental oxygen (O2) therapy: Administered to patients experiencing anaphylaxis, especially in the event of hypoxia & respiratory distress
  • Intravenous (IV) Fluids: Large-volume fluid resuscitation should be given immediately to patients with hypotension & those with incomplete response to IM Epinephrine
  • Patient positioning: If tolerated, patient should be in recumbent position, with lower extremities elevated to increase perfusion of vital organs; vomiting patients may be placed in a left lateral position
  • Please see Anaphylaxis Disease Management Chart for further discussion
