There are 3340 kinds of snake and 660 kinds of poisonous snake with disease causing harm to human, including pallas pit viper, cobra, king cobra, five-step snake, golden-ring snake, silver-ring snake, etc. Snake bites are common diseases in vast rural and mountain areas in China, and poisonous snake bites are one of important emergency treatment.

The Chinese cobra bite is mainly characterized by cytotoxin, local skin and soft tissue swelling and necrosis are obvious, the condition of a patient is rapidly changed after the patient is bitten, and serious local tissue necrosis is easily caused if the patient is improperly treated before a hospital or delayed hospitalization, and wound operation debridement, skin grafting and amputation are needed. Relevant experiments prove that after Chinese cobra venom is subjected to water bath at 60 ℃ for 10 minutes, the lower limbs of the big white rabbits are subjected to intramuscular injection, and the necrotic area of tissues around the wounds of the poisoned big white rabbits is found to be obviously reduced compared with the necrotic area of tissues around the wounds of the big white rabbits injected with snake venom which is not subjected to water bath treatment, the biochemical index value is also obviously reduced, and the difference is more obvious along with the higher water bath temperature. On the basis, further experiments show that after the cobra venom is injected into the lower limbs of the white rabbits, the electric iron is used for burning the toxin injection wounds immediately, the tissue necrosis area is obviously reduced compared with a group which is not burned after toxin injection, and the biochemical index value is obviously reduced. The experiment proves that the high temperature burning wound can destroy the snake venom components, reduce or even eliminate the toxicity of the snake venom, and obviously reduce the harm of the snake venom to human bodies.

The snake bite has acute morbidity and short course of disease, and serious complications and even death are easy to cause if the snake bite is not treated in time.
