The application provides a method, system, device and medium for determining anesthesia consciousness, which comprises: obtaining a target electroencephalogram signal of a target object; determining consciousness state information of the target object based on the target electroencephalogram signal through a consciousness determination model, wherein the consciousness state includes a conscious state, a light anesthesia state and an unconscious state; wherein the consciousness determination model is a machine learning model, and the consciousness determination model is obtained based on training samples, wherein the training samples include sample electroencephalogram signals, and the sample electroencephalogram signals include sample conscious state data, sample light anesthesia state data and sample unconscious state data. Through the trained consciousness determination model, the change in anesthesia depth of the target object during the operation and the smooth transition thereof can be accurately tracked on the basis of accurately determining the unconscious state or the non-unconscious state of the target object, so that the regulation of the amount of anesthetic drugs for the target patient during the operation is more accurate.

The present invention relates to an optical sensing element for detection of a narcotic, the optical sensing element comprising a fluorescent sensing compound provided on a substrate, wherein emission of the fluorescent sensing compound is quenched in the presence of the narcotic, and wherein the fluorescent sensing compound is non-polymeric and comprises an electron donor moiety, an electron acceptor moiety and a moiety that influences solubility of the compound in a solvent. Sensing devices incorporating the sensing element and methods of detecting narcotics are also described. 20 24 20 24 65 16 A pr 2 02 4 A B S T R A C T 2 0 2 4 2 0 2 4 6 5 1 6 A p r 2 0 2 4
