Deltamethrin poisoning

Decamethrin is also known as K-othrin as a 2.5% deltamethrin wettable powder, and Decis is 2.5% deltamethrin EC. The dosage form used in agriculture is 2.5% EC. Deltamethrin is one of the most toxic species of pyrethroid insecticides. It has a broad spectrum and low residual characteristics. It is effective against insecticides such as organophosphorus and has certain advantages. It is mainly used for control Pests such as cotton fields, vegetable fields, fruit trees and tea. Usually absorbed through the skin or oral poisoning. The mechanism of poisoning is not completely clear at present. It is believed that deltamethrin excites the extrapyramidal system, cerebellum, spinal cord, and peripheral nerves of the central nervous system because deltamethrin selectively slows the closing of the sodium gate of the nerve cell membrane m So that the sodium ion channel is kept open, so that the depolarization period of the action potential is prolonged, causing repeated discharge of peripheral nerves, which in turn increases the excitability of the spinal cord and peripheral nerves, and a series of corresponding clinical manifestations.
