If inadvertently bitten by a snake, not scared the life out of, we should first determine whether to snakebites.

　　Usually wound with two larger and deeper teeth marks can judge for snakebites. Without these two teeth marks, and within 20 minutes without pain, swelling, numbness and weakness symptoms, Snakebite is not. Only need to clean the wound, bleeding and bandaging. If conditions before sending it to the hospital tetanus vaccination needles can be.

　　Snakebite was highly toxic to the main symptoms : the case of hemorrhagic Venom : wound burning, and the proliferation of local swelling, wound around a purpura, silt grouper, blisters, Muddy blood from the wound exudate, or tissue necrosis of the skin, fever, nausea, vomiting, QiQiao bleeding. A sputum, hematuria, blood pressure lowering, Miosis, such as cramping. Victims after 6 -48 hours may lead to the injured died. So nervous Venom : wound pain, local swelling, lethargy, ataxia, ptosis, mydriasis and local weakness, swollen limbs, stuttering, drooling, nausea, vomiting, coma, respiratory difficulties and even respiratory failure. Injured in the 8 -72 probably died within hours.

　　Generally, the snakebite 10 -20 minutes later, the symptoms come back to the emerging. After being bitten, except sent to the hospital for treatment as soon as possible, for time to do emergency treatment is the most important :

　　1, as the slowdown of the injured action to reduce the spread of toxic blood. As poisoned, must be quiet and not to talk struggling Running to limit physical activities. The best stretcher can be used for transporting the injured.

　　2, ligation. In the wound above (near the heart side) a tourniquet or banners, and other tightly enclosed. Its tolerance level to be able to stop the blood and lymph to return later. China venom, in order not to expand the area of poisoning, it is necessary to the injured limb tightly enclosed, prevent blood flow caused greater area of poisoning. Ligation is not too hard, too much may cause necrosis of the body. Ligation after every 20 minutes, loose 1 -2 minutes, and then put on. In this way, the injured limb can guarantee the blood supply, will enable the blood and lymph back.

　　3, using clean water to wash the wound surface of the venom. But do not use well water, river water rinse, to wound infection.

　　4, if the critical moment around a fire and knife, it can debridement detoxification. Dagger put on the fire burned a burning, consumer disinfection, and then traces defanged by the direction of the longitudinal skin incision. the best marks of the two link up defanged. Squeeze dual use force, which could promote lymph outflows, are excluded from the venom. However, the cut in the not too deep, to avoid hurting physically. Some people think this is too bad, can not stand. However, in the venom of a crisis moment, in so doing, it is essential.

　　5, in addition to the above do not have under the circumstances, can also blow drug. But they should not suck caries, oral not damaged, ulcers degree. After the gully to spit it out as soon as possible, and Shu oral net. If oral wounds within, it can not be drugs, in order to prevent their venom has been infected.

　　6, the above method only emergency, if toxicity is a small snake bite can be basically intact, the theater was injured by poisonous snakes, may also gain time, poisoning also needs to take tablets and solution venom spread venom powder, So must send a nearby hospital for treatment. (Eg is not certain kind of snake venom should be killed together to the hospital.)
