Management of Wasp Sting in a Child

Immediate Stinger Management

• The American Academy of Allergy, Asthma, and Immunology recommends removing the stinger within 10-20 seconds by scraping or flicking it away with a fingernail to prevent additional venom injection 1, 2
• Never grasp the venom sac and pull it out, as this forces more venom into the tissue 1

Treatment Algorithm Based on Reaction Type

For Simple Local Reactions

• Apply cold compresses or ice packs to reduce local pain and swelling, as recommended by the American Academy of Allergy, Asthma, and Immunology 1, 2
• Give oral antihistamines to reduce itching and discomfort, according to the American Academy of Allergy, Asthma, and Immunology 1, 2
• Provide oral analgesics (acetaminophen or ibuprofen) for pain relief, as suggested by the American Academy of Allergy, Asthma, and Immunology 2

For Large Local Reactions

• Initiate a short course of oral corticosteroids promptly (within the first 24-48 hours) to limit progression of swelling, as recommended by the American Academy of Allergy, Asthma, and Immunology 1, 2
• Continue cold compresses and oral antihistamines, according to the American Academy of Allergy, Asthma, and Immunology 1

For Systemic Reactions/Anaphylaxis

• Administer intramuscular epinephrine 0.01 mg/kg (maximum 0.3 mg in children) into the anterolateral thigh immediately, as recommended by the American Academy of Allergy, Asthma, and Immunology 4, 1, 5, 2
• Epinephrine is the ONLY first-line treatment for anaphylaxis, according to the American Academy of Allergy, Asthma, and Immunology 4, 1, 5, 2

Post-Treatment Management

• Prescribe an epinephrine autoinjector and train the child's caregivers on proper use and indications, as recommended by the American Academy of Allergy, Asthma, and Immunology 1, 5, 3, 2
• Refer to an allergist-immunologist for venom-specific IgE testing and consideration of venom immunotherapy (VIT), according to the American Academy of Allergy, Asthma, and Immunology 1, 6, 3, 2

Rare but Serious Complications

• Multiple stings (typically >100) can cause toxic reactions from massive envenomation even in non-allergic individuals, potentially causing multi-organ dysfunction, as reported by the American Academy of Allergy, Asthma, and Immunology 4, 2
• Rare delayed reactions (serum sickness, vasculitis, neuritis) have been reported but are uncommon, according to the American Academy of Allergy, Asthma, and Immunology 4
