Determination of volatile anesthetics isoflurane and enflurane in mouse brain tissues using gas chromatography-mass spectrometry

Modern Anesthetic Ethers Demonstrate Quantum Interactions with Entangled Photons

Despite decades of research, the mechanism of anesthetic-induced unconsciousness remains incompletely understood, with some advocating for a quantum mechanical basis. Despite associations between general anesthesia and changes in physical properties such as electron spin, there has been no empirical demonstration that general anesthetics are capable of functional quantum interactions. In this work, we studied the linear and non-linear optical properties of the halogenated ethers sevoflurane (SEVO) and isoflurane (ISO), using UV-Vis spectroscopy, time dependent-density functional theory (TD-DFT) calculations, classical two-photon spectroscopy, and entangled two-photon spectroscopy. We show that both of these halogenated ethers interact with pairs of 800 nm entangled photons while neither interact with 800 nm classical photons. By contrast, nonhalogenated diethyl ether does not interact with entangled photons. This is the first experimental evidence that halogenated anesthetics can directly undergo quantum interaction mechanisms, offering a new approach to understanding their physicochemical properties.

An unusual case of anesthetic abuse by a full-face gas mask

The authors report a case of sniffing of halothane (Narcotan) by a 32-year-old man, master of pharmacy, through the military full-face gas mask. The liquid halothane had been applied on the scrubber of the gas mask and voluntarily inhaled. The sniffer was found dead in his flat, with the gas mask still fixed and sealed on his face. Because the authors have not encountered any report of such a case in the literature, they present and discuss this case in this article.
