经抢救治疗急性症状已明显缓解的有机磷农药中毒患者,在恢复期病情可再度恶化或突然死亡,这种现象称为反跳。本文就有机磷农药中毒反跳的几个问题作一概述。引起反跳的几个因素 1、洗胃、导泻不彻底或体表毒物未完全消除,残毒继续吸收。大量资料证明,口服有机磷农药中毒的患者即使超过12小时或更长时间,胃粘膜皱壁内仍有残存的有机磷。如未能及时彻底洗胃、导泻,切断毒源,则毒物会继续吸收,造成病情反复。但是,残毒的吸收是逐步进行的,残毒量与中毒量相比毕竟是小量,不应发生比中毒急性期更为
After salvage treatment of acute symptoms have been significantly alleviated in patients with organophosphate pesticide poisoning, the condition can be further exacerbated or sudden death in the recovery period, a phenomenon called rebound. This article gives an overview of some problems of organophosphorus pesticide poisoning rebound. Several factors that cause rebound 1, gastric lavage, catharsis is not complete or surface toxins are not completely eliminated, continue to absorb residual poison. A large number of data prove that, even if oral organophosphorus pesticide poisoning patients more than 12 hours or longer, there are still residual organophosphorus in the gastric mucosal folds. If not promptly thoroughly gastric lavage, catharsis, cut off the source of poison, the poison will continue to absorb, resulting in repeated illness. However, the absorption of residual drugs is gradual, the residual volume and poisoning volume is small, after all, should not occur more than the acute phase of poisoning more
