deltamethrin poisoning
Introduction
Introduction to permethrin poisoning Decamethrin, also known as K-othrin, is 2.5% deltamethrin wettable powder, and Decis is 2.5% deltamethrin emulsifiable concentrate. The dosage form used in agriculture is 2.5% emulsifiable concentrate. Deltamethrin is one of the most toxic species of pyrethroid insecticides. It has broad-spectrum and low-residue characteristics and is effective against insects that are resistant to organophosphates. It has certain advantages and is mainly used for prevention and treatment. Cotton fields, vegetable fields, fruit trees and tea pests. Generally absorbed by the skin or oral poisoning. The mechanism of poisoning is not fully understood. It is believed that the excitatory effect of deltamethrin on the extrapyramidal, cerebellum, spinal cord and peripheral nerves of the central nervous system is due to the selective slowing of the "m" gate of the neuronal membrane sodium channel by deltamethrin. The closure of the sodium ion channel keeps the sodium ion channel open, so that the depolarization period of the action potential is prolonged, causing repeated discharges of the peripheral nerves, thereby enhancing the excitability of the spinal nerve and peripheral nerves, and a series of corresponding clinical manifestations appear. basic knowledge The proportion of illness: 0.035% Susceptible people: no specific population Mode of infection: non-infectious Complications: cardiovascular disease, digestive ulcer
Cause
Cause of delpromethazine poisoning
Causes:
Poisoning is caused by aspiration and misuse.
Prevention
Permethrin poisoning prevention
In the production, transportation and storage of bromomethrin, it is necessary to strengthen the maintenance of equipment and utensils to prevent run, run, drip, leak, pay attention to complete packaging, prevent toxic substances from spilling out, dispense medicine, and carefully check the equipment before applying. Whether there is damage, overflow, if there is a fault, immediate maintenance, strict implementation of the safe operating system, after the application of the drug, the corresponding appliance should be processed.
1. Before dispensing and applying the medicine, it is necessary to carefully check whether the equipment is damaged or leaked. If there is any fault or immediate maintenance, strictly implement the safe operation system.
2. After application, the corresponding appliance should be disposed of.
3. In the process of production, transportation and storage of bromomethrin, it is necessary to strengthen the maintenance management of equipment and utensils to prevent running, rushing, dripping and leaking, pay attention to complete packaging, and prevent toxic substances from overflowing.
4. Popularize knowledge on prevention and treatment of poisoning.
Complication
Complications of permethrin poisoning Complications, cardiovascular disease, digestive ulcer
This product poisoning can cause complications of respiratory, digestive, cardiovascular, and neurological systems.
Symptom
Symptoms of chlorpyrifos poisoning Common symptoms convulsions, dizziness, abdominal pain, fatigue, coma, muscle fiber, tremor, loss of appetite, runny, mild poisoning
Poisoning mainly manifests as skin irritation and nervous system symptoms. Skin absorption first has local irritation symptoms, facial burning sensation, oral poisoning is nausea, vomiting, abdominal pain, etc. as the first symptom, occupational contact skin often has erythema, papule performance, light Poisoning headache, dizziness, fatigue, loss of appetite, muscle beating, severe poisoning, irritability, blurred vision, muscle fiber tremors, and even convulsions and coma. Most of the causes of death are convulsions and coma.
1. Poisoning mainly manifests as skin irritation and nervous system symptoms. Skin irritation has local irritation and a burning sensation on the face.
2, oral poisoning is nausea, vomiting, abdominal pain, etc. as the first symptom, occupational contact with the skin often has erythema, papules.
3, mild poisoning often manifested as headache, dizziness, fatigue, blurred vision, nausea, vomiting, loss of appetite, muscle beating.
4, severe poisoning can occur coma, pulmonary edema, myocardial and liver and kidney damage, muscle fiber tremor, and even convulsions and coma, and the causes of death are mostly convulsions and coma.
Examine
Examination of chlorpyrifos poisoning
Blood chE activity is normal, and urine septic determination is helpful for diagnosis.
Diagnosis
Diagnosis and identification of permethrin poisoning
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
In the differential diagnosis, the upper respiratory tract infection, heatstroke, food poisoning or other pesticide acute poisoning should be excluded. Because the odor of this disease is similar to that of organic phosphorus, it should be differentiated from organophosphorus pesticide poisoning, except for contact history. The erythrocyte cholinesterase activity of acute poisoning patients is mostly normal, and it can be treated with atropine test.
