Abstract: Due to their good safety, wide application scope and quick onset time, lipid emulsions are full of promise to reverse drug poisoning. In this review, a number of clinical case reports were summarized to analyze the detoxification effect of lipid emulsions on local anesthetic, antiarrhythmic, psychotropic and organophosphate poisoning, as well as the possible adverse reactions of lipid emulsions therapy.Meanwhile, the mechanisms underlying lipid emulsions therapy, such as lipid sink theory, enhanced body basal metabolism and positively affected cardiovascular function, were fully interpreted.Besides, a few potential solutions to the problems still existing in lipid emulsions therapy were proposed, in order to consolidate the understanding of lipid emulsions therapy and promote its rational application in reversing drug poisoning.
