Anaphylaxis is generally closely related to the occurrence of anaphylactic reaction, and the specific rescue process mainly includes cutting off the allergen, intravenous glucocorticoid, supplementing blood volume, confirming the opening of the airway, and cardiopulmonary resuscitation. 1. Cut off the allergen: after getting the allergenic substance, directly isolate the contact with the allergenic substance to prevent the allergic reaction from continuing and the shock from being relieved. 2. Injection of epinephrine: If necessary, treatment with epinephrine can be used. 3. Supplementation of blood volume: establish a channel through the vein, further supplement blood volume through intravenous rehydration, and closely monitor the patient’s physical indicators. 4. Confirmation of airway opening: it is necessary to undo the patient’s upper body clothing to prevent airway compression, in addition to observing airway patency, airway stenosis, tracheal intubation can be done if necessary, and oxygen treatment. 5. Cardiopulmonary resuscitation: some patients with cardiac arrest need immediate cardiopulmonary resuscitation to prevent irreversible hypoxic injury. Anaphylactic shock, after the rescue treatment, need to go to the emergency room for standardized treatment in time to avoid further danger.
