Abstract | ||||
ABSTRACT The assessment of patient brain state during surgery has long been an objective of research in the field of automated electroencephalogram (EEG), since EEG signals contain a wealth of information about brain functions, there are many approaches to analyzing EEG signals with spectral techniques. In this paper the bispectral analysis was applied to EEG signals obtained from patients under general anesthesia by using BSA software (bispectrum analyzer software version 3.31B) [1- 4]. The bispectral values (BIS) was normalized to 100 while awake and decreasing gradually to a level between 0 and20 as the patient was anaesthetized. The clinical signs such as heart rate (HR) and blood pressure (BP) of the level of anesthesia were observed simultaneously. Conclusion, the bispectral analysis of EEG signals obtained from patients under general anesthesia gives accurate index to measure depth of anesthesia. | ||||
