Fig 1 BIS (upper graph) and PSI (lower graph) at loss of consciousness (LOC1), awareness reaction (ROC1), loss of consciousness following the awareness reaction (LOC2) and at return of consciousness at the end of anaesthesia (ROC2). Graphs show individual values, mean (black line) and sd (dashed line) in all patients. An open symbol is used for the low infusion rate of remifentanil (0.1 μg kg−1 min−1, Groups 1 and 3), and a closed symbol for the high infusion rate of remifentanil (0.2 μg kg−1 min−1, Groups 2 and 4). Prediction probability (Pk) (sem) for awareness is given for each index. The dotted lines show the recommended value for the (upper) level of each index for general anaesthesia. *Significantly different from LOC1 and 2. §Significantly different from ROC1. #Significantly different from LOC2 (P<0.05).
