A Crossover Comparison of the Sensitivity and the Specificity between BIS and AEP in Predicting Unconsciousness in General Anesthesia

Figure 1

Systolic blood pressure (SBP), heart rate (HR), and respiratory data (RR) of two groups in four stages: base, sedation, unconsciousness, and anesthesia. On SBP, time effect was significantly different at the 0.05 level of significance; time and group interaction effect was significantly different at the 0.01 level of significance. On HR, both time effect and group interaction effects were significantly different at the 0.05 level of significance. On RR, no difference was found in both time effect and interaction effect. ‡ indicates significant difference from baseline. § indicates significant difference from sedation. † indicates significant difference from unconsciousness. On RR, no difference was found in both time effect and interaction effect.
