Review of the Hazards and Contraindications of Etomidate

International Journal of Toxicology, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 6, 2024

Etomidate, an ultrashort-acting non-barbiturate sedative derived from imidazole, exerts potent inhibitory effects on the central nervous system. It is commonly employed for induction of intravenous general anaesthesia or assisted anaesthesia. Recently, etomidate has emerged as alternative to narcotics and novel psychoactive substances, leading increasing trend abuse. Chronic overdose can result in irreversible brain damage various mental disorders. Severe cases may manifest disturbances, behavioural disorders, self-mutilation even death. The toxicological mechanisms remain poorly understood. Additionally, there limited information clinical symptoms histopathological changes associated with poisoning standardized detection methods blood, urine hair are lacking. Consequently, further research pathology development reliable testing crucial. This study reviews metabolism, distribution, adverse reactions, manifestations, toxicology etomidate.

Au Ordered Array Substrate for Rapid Detection and Precise Identification of Etomidate in E-Liquid Through Surface-Enhanced Raman Spectroscopy

Nanomaterials, Год журнала: 2024, Номер 14(23), С. 1958 - 1958

Опубликована: Дек. 6, 2024

Etomidate (ET), a medical anesthetic, is increasingly being incorporated into e-liquids for consumption and abuse as new psychoactive substance (NPS), leading to significant social issues. In this work, large-area Au micro- nano-structured ordered arrays were engineered surface-enhanced Raman spectroscopy (SERS) substrates fast detection precise identification of ET its metabolites. This array, characterized by abundant electromagnetic enhancement hotspots structural uniformity, imparts unique properties the SERS substrate, including ultra-sensitivity, spectral signal reproducibility, quantitative capabilities. Furthermore, it effectively mitigates interference from complex matrix e-liquids, facilitating rapid trace amounts molecules. technology can act preliminary screening method gold-standard spectroscopic analysis, on-site suspicious samples thereby enabling efficient verification.
