Dichlorvos poisoning is one of the more serious types of organophosphorus poisoning. If a large amount of dichlorvos is consumed without timely detoxification or without the application of symptomatic antidotes, thus causing liver and kidney insufficiency, patients will suffer from various conditions leading to shock and even sudden death. Severe dichlorvos poisoning can also invade the cardiac system and brain nerves causing respiratory paralysis, which can lead to respiratory failure and heart failure causing death. Therefore, low-risk poisoning is a relatively serious situation, and detoxification treatment must be actively given, otherwise death will easily occur. If a patient does develop dichlorvos poisoning, thorough gastric lavage, diuresis, diuresis and symptomatic treatment should be given first according to the treatment procedures for organophosphorus poisoning. If the patient has significant liver and kidney failure in severe cases, continuous blood purification should be considered for treatment.
