First aid measures for pediatric anaphylaxis are mainly to immediately stop contact with allergens or drugs, give oxygen, elevate the feet, and keep the airway open. If laryngeal edema asphyxia occurs, tracheotomy should be given immediately, and subcutaneous injection of 0.1% epinephrine should be given according to 0.01mg/kg, with a maximum dose of 0.5mg/dose, and repeated every 15 minutes if necessary. Immediate cardiopulmonary resuscitation is performed for respiratory arrest, and mouth-to-mouth artificial respiration as well as pediatric external cardiac compression is practiced. If persistent hypotension develops, administer an appropriate dose of dopamine IV to maintain blood pressure. Glucocorticoids such as dexamethasone, intramuscularly or intravenously, and methylprednisolone intravenously, every 6 hours if necessary, should be used. Desensitizers may be isoprozene, spinal or cervical as appropriate, and calcium may also be used. If laryngeal edema occurs and respiratory distress occurs, tracheal intubation or tracheotomy should be performed. Due to peripheral vasodilatation and insufficient blood volume, accelerated rehydration should be given, which is conducive to improving systemic and local circulation and promoting the excretion of allergic substances. Strictly monitor the vital signs of the pediatrician, and after the pediatrician is out of the danger period, he should still be observed for a period of time to prevent re-inducing shock.
