有机磷农药急性中毒经急救特效药治疗,急性症状明显缓解的恢复期,病情再次恶化、甚至死亡称反跳,多发生在急性中毒后的2～8天。现就其原因试作分析。 残留毒物继续吸:就诊过迟或不恰当、不彻底的洗胃及导泻致胃肠残留毒物继续吸收。口服超过12h或更长时间胃粘膜皱襞角残留有机磷;48h洗胃液中及3天后病人呕吐物仍有大蒜气味。 有机磷的肝内氧化:氧化后毒性增加300～600倍。对硫磷氧化为对氧磷毒性增加300倍,氧化乐果毒性比乐果高
Organophosphorus pesticide acute poisoning by emergency cure drugs, acute symptoms were relieved recovery period, the condition deteriorated again, and even death called rebound, occurred in acute poisoning after 2 to 8 days. Now on the reasons for trial analysis. Residual toxins continue to be drawn: late or inappropriate treatment, incomplete gastric lavage and catharsis continue to absorb residual gastrointestinal poison. Oral administration of organophosphorus remained at the folds of gastric mucosa for more than 12h or longer; garlic vapors still remained in the garlic after 48h of gastric lavage and for 3 days. Organophosphorus intrahepatic oxidation: increased toxicity after oxidation 300 to 600 times. Oxidation of parathion to oxygen toxicity increased 300-fold, omethoate toxicity than dimethoate
