百草枯是有机杂环类接触性除草剂,在农业生产中的使用是仅次于有机磷类的第二大农药,在当今社会生活性自服导致百草枯中毒患者的数量居高不下。百草枯中毒致死量较小,20%的百草枯农药10~30ml,致死率甚至高达90%~100%,且没有特效的解毒剂。大剂量中毒患者多死于多脏器功能衰竭,而中小剂量多死于不可逆性肺纤维化~(〔1〕)。有报道指出~(〔2-3〕),急性百草枯中毒患者合并不同程度的低钾血症,因此本研究回顾性分析152
Paraquat is an organic heterocyclic herbicidal contact herbicide. It is the second largest pesticide in agriculture after it is used in organophosphorus pesticides. Paraquat has a high incidence of paraquat poisoning in today’s society. Paraquat lethal dose is small, 20% of paraquat pesticides 10 ~ 30ml, the mortality rate as high as 90% to 100%, and no special antidote. Large doses of poisoning more deaths in multiple organ failure, and more small and medium-sized deaths due to irreversible pulmonary fibrosis ~ 〔〔〕 〔〕〕. It has been reported that ~ (〔〕 2-3〕, acute paraquat poisoning patients with varying degrees of hypokalemia, the study retrospectively analyzed 152
