Venomous snake bites are first treated by removing from the dangerous environment, extracting the poisonous fangs, proximal ligation, closure therapy, and antivenom. 1. Get out of the dangerous environment After being bitten by a venomous snake, it is necessary to get out of the dangerous environment. Usually there are many venomous snakes in the environment, so it is necessary to get out of the dangerous environment immediately to avoid being bitten again. 2. Extract fangs Venomous snake bites usually have remaining fangs, which should be carefully examined to find out the fangs and extracted to minimize the absorption of toxin. 3. Proximal ligature A bandage or elastic string should be tied proximally one joint above the wound to minimize the absorption of toxins into the bloodstream. 4. Closure therapy Localized closure therapy with drugs such as dexamethasone and lidocaine is used to reduce symptoms. 5. Antivenom treatment Symptomatic use of antivenom to neutralize the toxin. In conclusion, a snake bite should be treated briefly and then sent to the emergency department of a hospital for treatment. The above medications should be used in accordance with medical advice.
