There are three main types of snakebite poisoning?

You should be asking about how many snake venoms and various symptoms there are!

1.Poisonous snakes with nerve venom: there are krait, krait and sea snake, etc., the venom mainly acts on the nervous system, causing muscle paralysis and respiratory paralysis.

2.Venomous snakes with blood venom: bamboo leaf green, viper and turtle shell flower snake, etc., venom mainly affects the blood and circulatory system, causing hemolysis, hemorrhage, coagulation and heart failure.

3.Venomous snakes with both nerve poison and blood poison: there are pit vipers, large cobras and cobras, etc., and their venom has two properties: nerve poison and blood poison.

Clinical presentation. 1) Manifestations of nerve toxicity: numbness, loss of sensation, or only slight itching sensation in the wound.

The wound was not red and swollen obviously, and the bleeding was not much, and about half an hour after the injury, I felt dizzy, drowsy, nausea, vomiting and fatigue. In severe cases, dysphagia, hoarseness, aphasia, drooping eyelids, and diplopia may occur. Eventually, dyspnea, blood pressure drops, and shock may occur, resulting in hypoxia, cyanosis, and paralysis.

If the rescue is not timely, respiratory and circulatory failure will eventually occur, and the patient may die quickly. Neurotoxin is quickly absorbed, dangerous, and often ignored because of its mild local symptoms. The first and second days of the injury are the dangerous period, once this period is over, the symptoms can be improved quickly, and there will be no sequelae after **.

2) Manifestations of injuries caused by blood poisoning: the bite is rapidly swollen and continues to develop proximally, and the wound is severely painful and bleeding does not stop. The ** around the wound is often accompanied by blisters or blood blisters, subcutaneous ecchymosis, tissue necrosis.

In severe cases, there is extensive bleeding throughout the body, such as subconjunctival bruising, epistaxis, hematemesis, hemoptysis, and blood in the urine. In some cases, patients may also experience thoracic and intraperitoneal hemorrhage and intracranial hemorrhage, which can lead to hemorrhagic shock. The patient had head and tail, nausea, vomiting and diarrhoea, joint pain and high fever.

Because symptoms appear earlier and treatment is generally more prompt, the mortality rate can be lower than that of patients injured by nerve toxins. However, due to the acute onset and long-lasting course of the disease, the risk period is also longer, and the consequences are serious if it is too late. **There are often local and visceral sequelae after that.

3) Manifestations of injuries caused by mixed poisoning: symptoms of both nerve toxicity and blood toxicity. From the perspective of local wounds, it is similar to blood poisoning injuries, such as local redness and swelling, ecchymosis, blood vesicles, tissue necrosis and lymphadenitis.

From the whole body, it is similar to a nerve poison injury. The cause of death of such casualties is still mainly neurotoxic.
