Kidney bean poisoning, kidney bean poisoning, kidney bean poisoning, kidney bean poisoning Li Yong: "Manual for rapid examination of internal emergency" Kidney bean is also known as kidney bean, kidney bean, plum bean, kidney bean and so on. It contains two kinds of toxic substances: legumin (which has blood coagulation effect) and saponin (hemolysin which strongly stimulates mucous membrane and can destroy red blood cells). Soybean can only be destroyed after a long period of boiling, and saponin can only be destroyed at 100℃. In addition, when kidney beans are left for 24 hours or more, their nitrite content will increase greatly, which can increase blood methemoglobin and cause cyanosis. Ma Zhongfu: "Emergency medicine" beans, also known as green beans, lentils, green beans and plum beans, are one of the vegetables that families and restaurants often eat. There are two toxic substances in beans: soybean and saponin. All kinds of edible beans contain soybeans, and soybean skin often contains saponin. The toxin content varies slightly depending on the variety and origin. Sufficient heating can eliminate its toxic effect. Poisoning cases mostly occur in autumn and early winter, and collective poisoning is more common and should be paid attention to. Ma Zhongfu: Bean poisoning in emergency medicine is mainly caused by improper cooking. In order to keep its bright green appearance, the chef failed to cook it thoroughly and fully destroyed the toxic components in the beans. After eating a lot, the toxins were absorbed by the stomach. Among them, soybean protein is a kind of phytotoxic protein, which has coagulation effect; Saponins have a strong stimulating effect on mucosa and contain hemolysin, which can destroy red blood cells; In addition, trypsin inhibitor and kidney beans left for more than 24 hours lead to a large increase in nitrate content in beans, which can also be one of the causes of poisoning. Ma Zhongfu: The incubation period of "emergency medicine" is 1 ~ 5 hours. The clinical manifestations may include nausea, vomiting, abdominal pain, diarrhea, abdominal distension, dizziness, headache, fever, cold sweat, numbness of lips and limbs, and even gastrointestinal bleeding in severe cases, including cyanosis of lips, dyspnea, palpitation and shortness of breath. Ma Zhongfu: Routine examination of blood, urine and feces in emergency department showed that occult blood in stool was positive, and the electrolyte was low in sodium and chlorine. Li Yong: Manual for Rapid Examination of Internal Emergency (1) History: History of eating undercooked kidney beans. (2) Clinical manifestations: the incubation period is 0.5 ~ 5 hours, and the degree of poisoning is consistent with the food intake. The first manifestations are nausea, vomiting, abdominal pain, diarrhea, dizziness and headache, which may be accompanied by palpitation, chest tightness, cold hands and feet, numbness of limbs and fever. Short course of disease, quick recovery and good recovery. Ma Zhongfu: Emergency Medicine has a history of eating green beans, which can be diagnosed according to clinical manifestations. It needs to be differentiated from food poisoning such as acute gastroenteritis. Li Yong: The Manual for Rapid Examination of Internal Emergency (I) usually does not need special treatment. After vomiting and diarrhea, the symptoms healed quickly. (2) In severe cases, glucose saline and vitamin C can be infused to promote the excretion of poisons and maintain electrolyte balance. (3) When there is coagulation, intravenous infusion of low molecular dextran and low molecular heparin can improve microcirculation, reduce blood viscosity and prevent platelet aggregation. When hemolysis occurs, urine is alkalized with adrenocortical hormone, blood transfusion and sodium bicarbonate. Ma Zhongfu: First-aid drugs (1) induce vomiting in time to minimize the absorption of poisons, and gastric lavage and catharsis can be carried out if necessary. (2) Symptomatic treatment: Patients with severe vomiting and diarrhea can use atropine and belladonna tincture. At the same time, rehydration should be given to maintain the balance of water and electrolyte, or large dose of vitamin C should be injected intravenously to promote the discharge of poisons. When there is hemolysis, adrenal cortical hormone, blood transfusion and sodium bicarbonate can be used to alkalize urine. Ma Zhongfu: Emergency medicine has a good prognosis and few deaths. After beans are cooked, the toxin is completely destroyed, so eating beans after cooking is the fundamental way to prevent poisoning. Bean product poisoning mostly occurs in groups (such as canteens), so we should raise our awareness of preventing poisoning.
