After rat poisoning, we should actively take rescue and treatment measures, and generally carry out gastric lavage, emetic, diuretic, etc. to accelerate the discharge of poison from the body, reduce the absorption of poison, and ensure the life safety of patients. There are many kinds of rat poison, different rat poison can be used to wash the stomach with different potions, but in the absence of a clear type of rat poison, the stomach is generally first washed with water, you can use mannitol powder for diarrhea, which can well accelerate the discharge of rat poison from the body. If you can clarify the type of rat poison, you can use a targeted approach to gastric lavage, such as the common zinc phosphide rat poisoning, you can use potassium permanganate solution for gastric lavage, because potassium permanganate can make zinc phosphide lose its toxicity, and can accelerate its excretion from the body. You can also use copper sulfate solution for gastric lavage, because zinc phosphide can generate copper phosphide precipitate after encountering copper sulfate solution, which can effectively reduce the absorption of the poison and promote the rapid discharge of the poison from the body.
