The most common symptoms of food poisoning are severe vomiting and diarrhea, accompanied by upper and middle abdominal pain. People with food poisoning often have dehydration symptoms due to vomiting and diarrhea, such as dry mouth, sunken eye sockets, skin loss of elasticity, cold limbs, weak pulse and low blood pressure. Finally, it will cause shock. Therefore, patients must be hydrated, and normal saline can be input if conditions permit. Let people with mild symptoms stay in bed. If it's just stomach upset, drink warm water or diluted salt water, and then put it into your throat to induce vomiting. If the poisoned person is found to have symptoms of shock (such as cold hands and feet, blue face, and decreased blood pressure). ), you should lie flat immediately, raise your lower limbs as much as possible, and seek medical treatment immediately. Chemical food poisoning Chemical food poisoning mainly refers to food poisoning caused by some toxic metals, nonmetals and their compounds, pesticides and nitrite. The main causes of chemical food poisoning are eating toxic chemicals by mistake or eating food contaminated by chemicals. The main characteristics of chemical food poisoning are: (1) rapid onset. The incubation period is short, mostly from a few minutes to several hours, and a few are more than one day. (two) the degree of poisoning is serious, the course of disease is longer than that of bacterial toxin poisoning, and the morbidity and mortality are high. (3) The seasonality and regionality are not obvious, and the poisoned food has no specificity, and most of them are caused by eating food contaminated by chemical substances by mistake, which is very accidental. Bacterial food poisoning Bacterial food poisoning is the most common kind of food poisoning, which is caused by people eating food containing a lot of live bacteria or bacterial toxins. The main characteristics of this kind of food poisoning are: (1) usually has obvious seasonality, which mostly occurs in hot season, and generally occurs in May-65438+10. On the one hand, higher temperature creates favorable conditions for bacterial reproduction; On the other hand, during this period, the human body's defense ability decreases and its susceptibility increases, so bacterial food poisoning often occurs. (2) The food causing bacterial food poisoning is mainly animal food, such as meat, fish, milk, eggs, etc. A few are plant foods, such as leftovers, glutinous rice cakes and flour fermented foods. (3) People with decreased resistance, such as patients, the elderly and children, are prone to bacterial food poisoning, with high incidence and severe acute gastroenteritis, but the mortality rate of such food poisoning is low and recovery is good. Symptoms and rescue of food poisoning ① Any food contaminated by bacteria (such as Salmonella, Staphylococcus, Escherichia coli, Botox, etc.). ) and its toxins, or food containing toxic chemicals, or food itself contains natural toxins (such as puffer fish, poisonous mushrooms, sprouted potatoes, etc.). ) called food poisoning. Food poisoning mostly occurs in summer and autumn when the temperature is high. It can be seen that individual cases can also be regarded as collective poisoning (such as canteens and banquets). ② The most common symptoms of food poisoning patients are severe vomiting and diarrhea, accompanied by upper and middle abdominal pain. People with food poisoning often have dehydration symptoms due to vomiting and diarrhea, such as dry mouth, sunken eye sockets, skin loss of elasticity, cold limbs, weak pulse and low blood pressure. Finally, it will cause shock. Therefore, patients must be hydrated, and normal saline can be input if conditions permit. Let people with mild symptoms stay in bed. If it's just stomach upset, drink warm water or diluted salt water, and then put it into your throat to induce vomiting. If the poisoned person is found to have symptoms of shock (such as cold hands and feet, blue face, and decreased blood pressure). ), you should lie flat immediately, raise your lower limbs as much as possible, and seek medical treatment immediately. ③ Those who eat puffer fish will cause numbness of tongue or hands and feet 2-3 hours after eating. Early vomiting was effective and was rushed to the hospital for emergency treatment. If it is delayed for more than 4 hours, it will form respiratory paralysis and die. In addition to gastrointestinal symptoms, poisonous mushroom poisoning can also be seen as spasms, drooling, hallucinations, shaking hands and other symptoms. First aid is to induce vomiting and then send it to the hospital. (4) If it is collective poisoning, rescue work should be organized. And promptly notify the health and quarantine department to carry out quarantine. It is best to keep leftover food for diagnosis, treatment or quarantine.
