The bite of a non-venomous snake can leave 1 or 2 rows of small teeth marks on the skin, slightly painful, red, blistering, and generally no systemic reaction. If a similar wound of unknown origin exists on the body, it is recommended to seek prompt medical attention and have the patient evaluated by a physician based on previous visits, as well as wound status and systemic reactions, and targeted treatment. Usually, non-venomous snake bites are rarely accompanied by symptoms other than local reactions, but it cannot be ruled out that a very small number of patients may develop allergic symptoms. Treatment is relatively simple, mainly disinfection of the wound to avoid secondary infection. If allergy symptoms exist, when the symptoms are mild, such as itching and rash, oral loratadine and cetirizine can be administered to help the patient. Patients with more severe allergy symptoms, such as respiratory distress, etc., need to be treated with first aid. In case of poisonous snake bite, it can usually manifest as general weakness, muscle tremors, dizziness, slurred speech, limb flaccidity, respiratory depression, etc. Untimely treatment can lead to multi-organ and multi-system failure, and even local tissue necrosis, which can be life-threatening in severe cases. Therefore, for such snake bites, first aid is more critical. First aid measures include avoiding running, tying the proximal end of the injured limb, then squeezing the wound with your hand to drain the venom and disinfecting it, but not cutting the wound. At the same time, you should also actively call for help to seek medical treatment in a timely manner. It is important to note that you should not take the common treatment measures in film and television on your own, such as sucking with your mouth and removing the affected limb, to avoid aggravating the condition. After seeking medical attention, doctors will perform professional wound treatment, as well as injecting antivenom and actively controlling the accompanying symptoms to facilitate the patient’s recovery. In daily life, it is not necessary to set foot in weedy mountains, forests, etc. If it is necessary to go to similar places, you can prepare a longer wooden stick to repel snakes by beating the grass, and you can carry some staghorn powder with you to reduce the chances of snakes and insects getting close to you to reduce the occurrence of such incidents.
