Review of the Hazards and Contraindications of Etomidate.
Etomidate, an ultrashort-acting non-barbiturate sedative derived from imidazole, exerts potent inhibitory effects on the central nervous system. It is commonly employed for the induction of intravenous general anaesthesia or assisted anaesthesia. Recently, etomidate has emerged as an alternative to narcotics and novel psychoactive substances, leading to an increasing trend of abuse. Chronic overdose of etomidate can result in irreversible brain damage and various mental disorders. Severe cases may manifest as mental disturbances, behavioural disorders, self-mutilation and even death. The toxicological mechanisms of etomidate remain poorly understood. Additionally, there is limited information on the clinical symptoms and histopathological changes associated with etomidate poisoning and standardized detection methods for etomidate in blood, urine and hair are lacking. Consequently, further research on toxicological pathology and the development of reliable testing methods is crucial. This study reviews the metabolism, distribution, adverse reactions, poisoning manifestations, toxicology mechanisms and testing methods of etomidate.
期刊介绍:
The International Journal of Toxicology publishes timely, peer-reviewed papers on current topics important to toxicologists. Six bi-monthly issues cover a wide range of topics, including contemporary issues in toxicology, safety assessments, novel approaches to toxicological testing, mechanisms of toxicity, biomarkers, and risk assessment. The Journal also publishes invited reviews on contemporary topics, and features articles based on symposia. In addition, supplemental issues are routinely published on various special topics, including three supplements devoted to contributions from the Cosmetic Review Expert Panel.
