In acute poisoning the maintenance or reconstitution of vital functions is the first and most critical action. All subsequent therapies and the prognosis depend on the identification of the causative agent and on information about substance-specific toxicity. Despite incomplete evidence the concept of harm reduction by decreased absorption of the toxicants and by shortening the course of illness is consistent with toxicokinetic-dynamic principles and is therefore still used by clinical toxicologists. All these treatment options have to be seen within the context of the prognosis and the time course of an individual case of poisoning. Treatment options of gastrointestinal decontamination are (in decreasing order of importance) single-dose activated charcoal, whole bowel irritation, and gastric lavage. Induced emesis by ipecac syrup is not practiced anymore. Enhanced elimination techniques are multiple-dose activated charcoal, urine alkalinization, and extracorporeal techniques such as hemodialysis and hemoperfusion. Enhanced elimination is only beneficial in toxicants with long half-life. Antidotes are directed against specific agents and therefore may be used only in a limited number of cases. The procurement of specific antidotes, often hardly available and not approved, is facilitated if the supply is organized in a transparent and standardized manner.
在急性中毒中,维持或恢复重要功能是首要且最关键的行动。所有后续治疗及预后均取决于致病剂的识别以及有关物质特异性毒性的信息。尽管证据不完整,但通过减少毒物吸收和缩短病程来降低危害的概念符合毒代动力学 - 动力学原理,因此临床毒理学家仍在使用。所有这些治疗选择都必须结合个体中毒病例的预后和病程来考虑。胃肠道去污的治疗选择(按重要性降序排列)为单剂量活性炭、全肠道灌洗和洗胃。不再使用吐根糖浆诱导呕吐。强化清除技术包括多剂量活性炭、尿液碱化以及血液透析和血液灌流等体外技术。强化清除仅对半衰期长的毒物有益。解毒剂针对特定毒物,因此仅在有限的病例中使用。如果以透明和标准化的方式组织供应,通常难以获得且未经批准的特定解毒剂的采购将更加便利。
