Primary
| Measure | Time frame |
|---|---|
| Percentage of time during which an appropriate state of anesthesia was obtained within the operation time. An appropriate state of anesthesia shall be satisfied when the following three conditions are satisfied; (1) Percentage of time that BIS is maintained within the target range (35-55) from start to end of surgery, (2) The number of incidences of hemodynamic changes (increase in pulse rate and blood pressure) observed from start to end of surgery except within 5 minutes after administration of inotrope, (3) Percentage of time that muscle relaxation is maintained within the target range (0 < TOF count <= 1) from start to end of surgery | — |
