Anesthesia state evaluation system and method suitable for patients of different ages

The invention provides an anesthesia state evaluation system and method suitable for patients of different ages. The anesthesia state evaluation system suitable for the patients of different ages comprises a signal acquisition module used for acquiring electroencephalogram signals of the patients of different ages in different states before and after an operation; the signal processing module is used for processing the electroencephalogram signals and establishing a human body consciousness evaluation model according to the processed electroencephalogram signals; and the anesthesia state evaluation module is used for collecting the current electroencephalogram signal of the current patient and judging the anesthesia state of the current patient according to the human body consciousness evaluation model. According to the method, anesthesia state monitoring is more objective and scientific, it is ensured that the evaluation result of the current anesthesia state of the patient is obtained quickly and efficientl
