What are the symptoms of organophosphorus pesticide poisoning?

What are the symptoms of organophosphorus pesticide poisoning? Please introduce that organophosphorus compound is a kind of insecticide, which is widely used in agriculture and medical health, and most of them have varying degrees of toxicity, which can be poisoned by entering fur economic animals through digestive tract, respiratory tract, skin and mucosa. there are more than 10 kinds of organophosphorus pesticides that can cause poisoning, such as 1605, 1059, trichlorfon, dichlorvos and dimethoate. Feeding grains, weeds, vegetables or contaminated feed after organophosphorus pesticides were spread, organophosphorus pesticides were spread near the fur economic animal farm, and the liquid was splashed and inhaled by the fur economic animals; the use of instruments for preparing organophosphorus pesticides to prepare feed, or drinking contaminated water can cause organophosphorus poisoning in fur economic animals. In addition, when feeding carcasses and by-products of animals, poultry and other animals who died of organophosphorus pesticide poisoning, or using organophosphorus pesticides to treat parasitic diseases in vivo and in vitro, improper dosage and high concentration can also cause poisoning. According to the dose, process and performance of poisoning, it can be divided into acute poisoning and chronic poisoning. During acute poisoning, the diseased animals have dyspnea, drooling, foaming at the mouth, tears, snorting, conjunctival and oral mucosal cyanosis: dilated pupils; diarrhea, thin faeces with blood, frequent defecation and urination; cold skin; sensitive to external stimuli, Xingguo state, hearing failure, visual response inhibition. Hindlimb paralysis, unable to stand, difficulty in walking, muscle groups all over the body showed varying degrees of spastic contraction, skeletal muscle tremor, full peak collapse, and finally died of respiratory central paralysis or heart failure. In chronic poisoning, the sick animals eat less or even no food, gradually lose weight, movement disorders, branch incoordination: long-term diarrhea feces with exfoliated intestinal mucosa or blood, respiratory secretions increase, resulting in dyspnea, and finally body temperature drop, and death occurs. Autopsy showed visible mucosal cyanosis, a large amount of mucous secretions in the mouth, and pulmonary hyperemia and edema filled with foam-like mucus in the bronchus. Substantial organ congestion and bleeding, meningeal congestion, gastrointestinal mucosal exfoliation with bleeding spots or bleeding spots. According to the history of contact with organophosphorus pesticides, nerve oversalivation, pupil narrowing, muscle tremor, dyspnea and other typical symptoms, a preliminary diagnosis can be made, and it is best to collect the disease materials for toxicological identification in order to establish the final diagnosis. To prevent this disease, it is necessary to keep and use organophosphorus pesticides, correctly control the dose and concentration, strengthen nursing, strictly prevent eating or biting each other, and do not take it with alkaline drugs when using trichlorfon to treat parasites in animals. When crops that have been sprayed with organophosphorus pesticides are used as feed, they should be fully cleaned for safety tests before feeding animals. It is forbidden to feed fur economic animals with carcasses and by-products of animals, poultry and other animals (rabbit, fox, mouse, fish, etc.) that die as a result of organophosphorus poisoning. Acute poisoning should be rescued quickly. Due to oral organophosphorus pesticide poisoning, immediately use 2% sodium bicarbonate solution 1% soda or 0. 1% potassium permanganate solution (1605 poisoning can not be used potassium permanganate) repeated gastric lavage to remove unabsorbed toxicants, but if it is oral trichlorfon poisoning, gastric lavage can be done with alkaline solution, while gastric lavage with 115000 potassium permanganate solution or normal saline. For symptomatic treatment, hypodermic injection of barbital (10% isobarbital sodium solution) is available for relieving spasms, 10 mg per kilogram of body weight for minks and 30 milligrams per kilogram of body weight for silver and black foxes, preferably once at intervals of several days, several times in a row. Parathion is given at a full weight of 30 mg per kilogram, diluted with 5% glucose solution and biological saline, followed by slow intravenous injection. However, alkaline drugs must not be used in combination. Click to get more pesticide application techniques
