How to deal with anaphylactic shock

Allergy is a symptom caused by the body's overreaction to external stimuli. There are many causes and symptoms of allergies, such as fever, rash on the body, etc. Shock caused by allergies is a more serious type of allergic reaction. If not treated in time, it may lead to organ failure and even threaten our lives. So how should we deal with anaphylactic shock in daily life?

1. Immediately stop entry and remove suspected allergens or causative drugs. Ligate the limbs above the injection or insect bite site to slow down absorption. You can also block the injection or sting site with 0.005% epinephrine. Lie flat, breathe oxygen, and keep the airway open.

2. Immediately give 0.1% epinephrine, first by subcutaneous injection, followed by intravenous injection, followed by 5% glucose drip to maintain intravenous administration. Epinephrine can rapidly relax bronchospasm through its β-receptor effect and constrict peripheral small blood vessels through its α-receptor effect. It can also counteract the release of some mediators of type I allergic reactions, so it is the first choice drug for treating this disease and can be used repeatedly several times during the course of the disease. Generally, after 1 to 2 injections of epinephrine, most patients' shock symptoms can gradually recover within half an hour. On the contrary, if the shock persists and does not improve, it is a serious case and dexamethasone and hydrocortisone succinate should be injected intravenously as soon as possible. A number of anti-shock drugs with longer-lasting efficacy and fewer side effects, such as norepinephrine, alamin (metahydroxyamine), etc., may also be used as appropriate. At the same time, vasoactive drugs are given and blood volume is replenished in time.

3. For anti-allergic and symptomatic treatment, chlorpheniramine or promethazine are commonly used. Because when the patient is in anaphylactic shock, the allergic threshold is very low, which may turn some drugs that were not originally allergic into allergens. Therefore, excessive use of medication should be avoided when treating this disease.

Anaphylactic shock can lead to very serious consequences. If you find that you are prone to allergies, you should avoid excessive contact with allergens in order to prevent allergic reactions. If someone around you unfortunately develops symptoms of anaphylactic shock, we can refer to the above methods to provide first aid and then send them to the hospital for treatment in time.
