摘要
NARCOTREND index （NI） is based on studies ofnormal human brain electrical data. It uses anordinary electrode to collect and analysis brainelectrical signals immediately at any positionof the head, to display the state of consciousness and depthof anesthesia of patients on the touch screen afterautomatic analysis and classification, so as to guide doseadjustment of anesthetics. NI may make the consciousnessand depth of anesthesia monitoring safe, simple, accurate,and economic. It is important that NI is more accurate thanclassical electroencephalographic variables.^1 Weber et al2believed that the NI was an objective and true index in theevaluation of propofol sedation in children.
