A water snake bite first distinguishes whether the snake is poisonous or not, and if it is impossible to distinguish, it is best to remember the snake’s appearance or characteristics to help the doctor take better treatment measures. After being bitten by a poisonous snake, the bite site will immediately show numbness symptoms, bleeding and other symptoms. After being bitten by a snake, use a soft rope or other items that can be tied, and tie a joint in the wound. If you can not rush to the hospital, immediately rinse the wound, and then disinfected with hydrogen peroxide rinse. If possible, use potassium permanganate solution to better, use a knife that has been sterilized, cut the skin where the bite was crossed, and squeeze out the snake venom while sending it to the hospital.
