农药中毒时洗胃的目的,一是把进入体内的毒物迅速排出体外,二是希望通过洗胃液使残留毒物分解失效或降低毒性。因此,及早、彻底洗胃,迅速清除胃内毒物,阻断胃肠粘膜的继续吸收,这是抢救误服农药中毒病人的重要关键。目前一些基层单位对洗胃液的选择注意不够,常将高锰酸钾溶液作为农药中毒常规的通用洗胃液,这是很不妥当的。不同的化学农药,应根据其理化特性,选择针对性强的洗胃液。有机磷农药中较多品种属硫代磷酸酯类如1605、1059、3911、苏化203、乐果、杀螟松、马拉硫磷、亚胺硫 The purpose of gastric lavage when pesticide poisoning, first, the poison into the body quickly excreted, and second, through the gastric lavage fluid to make the residual toxic decomposition failure or reduce toxicity.

At present, some grassroots units pay insufficient attention to the choice of gastric lavage fluid, and often use potassium permanganate solution as a common general gastric lavage fluid for pesticide poisoning. This is not appropriate. Different chemical pesticides, should be based on its physical and chemical properties, select the targeted gastric lavage fluid.
