What is the emergency protocol for anaphylactic shock?

Anaphylactic shock is a highly critical clinical condition that requires immediate resuscitation without delay once it occurs. First, the medication causing the anaphylactic shock must be immediately discontinued, and emergency treatment should be initiated on site. Simultaneously, the patient’s vital signs—including blood pressure, pulse, respiration, and body temperature—must be closely monitored. In terms of emergency treatment, intramuscular injection of 0.1% epinephrine is generally the first-line therapy, typically administered at a dose of 0.3–0.5 mL per dose; for children, the dosage should be relatively reduced. If the response is inadequate, the dose may be repeated every 10–20 minutes. Alternatively, dexamethasone 5–10 mg or antihistamines such as diphenhydramine may be administered via intramuscular injection. Additional management measures include preparation for possible tracheotomy or endotracheal intubation.
