Dichlorvos is a kind of organophosphorus pesticide, if you accidentally drink it in, you should immediately give vomiting, gastric lavage, and diarrhea to try to eliminate the dichlorvos from your body as soon as possible, so as to reduce its absorption by the gastrointestinal mucosa and cause systemic toxic reactions. Among them, stomach lavage can usually be done repeatedly with water or saline, until the gastric juice is washed out without the taste of garlic. In addition, detoxification and symptomatic drugs can be applied, such as detoxification and chlorophacin, which are targeted detoxification drugs for organophosphorus pesticide poisoning. If there is respiratory and cardiac arrest, cardiopulmonary resuscitation should be given. If the patient has been in a state of shock, rapid rehydration and anti-shock medication can be given for anti-shock treatment.
