Disclosed are an anesthesia depth monitoring device and method. According to the anesthesia depth monitoring device, by carrying out analysis and transverse comparison on a bispectral index, noxious stimulation data and neuromuscular blockade depth data, injected medicines are respectively controlled, the interference of the neuromuscular blockade recovery and the noxious stimulation strengthening on the electroencephalogram monitoring anesthesia depth is effectively eliminated and the monitoring on the electroencephalogram anesthesia depth can accurately and effectively reflect an anesthesia depth value of a patient. Meanwhile, by the anesthesia control of carrying out interference elimination on the monitoring on the electroencephalogram anesthesia depth and then carrying out optimization, the anesthesia depth can be controlled stable like a straight line, the machine control of the integral anesthesia process is implemented, the condition of judging the anesthesia process mainly by the anesthesia experience of a doctor is changed, the influence of the individual difference of patients is overcome, and the safety of the anesthesia process is ensured to the greatest extent.
