HFCP is one of pyrethroids, and this type of pesticide can be absorbed through the skin, gastrointestinal tract and respiratory tract, and is a kind of neurotoxin. Pyrethroid drug poisoning is one of the more common poisoning characteristic diseases in the emergency department. The first aid method is not essentially different from other drug poisoning, and can be mainly divided into three parts: removal of poison, detoxification treatment and symptomatic treatment. Pyrethroid poisoning has a better prognosis and lower mortality rate in most clinical cases. If it is skin contact, take off the poisoned clothes as soon as possible and rinse the poisoned skin with soap and a lot of water; if it is dripping into the eyes, turn over the eyelids and rinse with a lot of water; if it is inhalation poisoning, get away from the poisoning scene quickly and bring the patient to the fresh air; if it is accidental poisoning, it is not recommended to induce vomiting by oneself and go to the hospital as soon as possible. In case of poisoning by inhalation, it is not recommended to induce vomiting by oneself, but to go to the hospital as soon as possible for gastric lavage, and activated charcoal can be instilled through the gastric tube to adsorb the residual poison, while giving diuretic treatment. If there are patients with frequent convulsions, impaired consciousness, or coma, toxic pulmonary edema and other serious manifestations, blood purification treatment such as hemoperfusion or hemodialysis should be carried out as soon as possible to remove the poison absorbed into the blood. Second, detoxification treatment: This is the key to the treatment of drug poisoning, but pyrethroids do not have a corresponding antidote, in the clinical antagonism of symptoms is the main, more commonly used drug is atropine. Atropine can control the symptoms of salivation and increased sweating that occur after poisoning, and is also beneficial for the prevention and treatment of pulmonary edema, but it should be noted that the dosage of atropine must be careful so as not to cause atropine poisoning with too large a dose. Pyrethroid poisoning may also induce severe convulsions, and the application of diazepam or barbiturate sedative-hypnotics may be considered for the treatment of these symptoms. There are clinical studies suggesting that the Chinese herbal medicines geranium and salvia may be effective in controlling symptoms and shortening the course of treatment, and can be considered for use. Third, symptomatic treatment: patients can accelerate the excretion of toxins through intravenous fluids, use energy combination, vitamin B6, vitamin C and other drugs as appropriate, replenish water electrolytes to maintain balance, choose antibiotics to prevent infection, etc., and use pantoprazole to protect the gastric mucosa.
