A 14-month-old boy, weigh...

A 14-month-old boy, weighing 10 kg, was brought by his parents with complaints of reddish bumps all over his body. The bumps appeared after the child was given food containing fish 1 hour ago. The mother has a history of allergy. On physical examination, the child appeared fussy and restless. There were generalized well-demarcated erythematous plaque lesions on the face, trunk, hands, and feet, along with palpebral edema. On auscultation, there was minimal stridor, nasal breathing was noted as +/+, and minimal retractions were observed. The patient was diagnosed with acute urticaria with an anaphylactic reaction. Evaluation of airway, breathing, and circulation was carried out. Oxygen was administered adequately, and an Epinephrine injection 1:1000 at 0.01 mL/kg IM (max. 0.3 mL) was given in the 1/3 middle anterolateral thigh. Epinephrine inhalation 1:1000 at 0.5 mL/kg (maximum 5 ml) was also administered due to the presence of stridor. After improvement (+1 hour after epinephrine), Diphenhydramine at 1 mg/kg/time and Methylprednisolone at 1-2 mg/kg/day divided into 3 doses (for the first 24 hours, then switched to PO until a total of 3-4 days) were given. Observation hospitalization for 24-72 hours and parental education were recommended. A complete peripheral blood test, IgE examination, and skin test were planned as indicated.
