The time for pesticide poisoning to be excreted from the body, or for metabolism to be completed, must be determined by the patient’s condition. If the patient’s poisoning symptoms are relatively mild and the dose of pesticide taken orally or exposed to is not large, usually about 1-3 days can basically metabolize it. However, if the exposure dose is relatively large or the oral dose is relatively large and the poisoning symptoms are severe, the metabolism time will be longer, usually taking 5-7 days or longer, to be able to metabolize. In the case of organophosphorus pesticide poisoning, the determination of whether the metabolism is complete can be based on the smell of the gastric lavage fluid. If the washed gastric juice still smells like garlic, it proves that there is organophosphorus poison left in the body, and in this case the gastric lavage must be continued until the washed gastric juice has no smell.
