Assessment
Primary outcomes The standard deviation of the bias between arterial pressures obtained by ClearSight versus by an arterial catheter.
The bias and 95% limits of agreement of arterial blood pressure between two devices (Bland-Altman method for repeated measurements)
Key secondary outcomes (1) The beta coefficient of the bias using the linear mixed-effects model between arterial pressures obtained with ClearSight versus with an arterial catheter
(2) The percentage error of the arterial pressure
(3) Interclass correlation coefficients of the arterial pressure
(4) The beta coefficient of the CO, SV, SVV calculated by the mixed linier regression model.

Results
Compared with the case of PI>1, the adjusted SD of bias in the case of PI<=1 was 1.4 times (95% confidence interval; 1.3 to 1.4) in systolic arterial pressure, 1.5 times (95% confidence interval 1.3 to 1.6) in diastolic arterial pressure, and 1.3 times (95% confidence interval 1.2-1.5) in mean arterial pressure.

Other
Other related information An invasive arterial catheter (FloTrac sensor)is inserted to the left radial artery after induction of the gengeral anesthesia. ClearSight finger cuff and probe of the pulse oximeter are also attached to the left hand finger.
Data collection: arterial blood pressure, cardiac output, stroke volume, stroke volume variation, perfusion index, and body temperature.
Data collection period:
One measurement period: 15 minutes
one data point: averages of 1 minute blood pressure data
-Operating room
The measuring period will be set at least 8 times during operation.
We plan to collect more than 120 points (i.e. 8*15=120 points) per one patient.
-Intensive care unit
Performing at least 2 data collection periods from 1 hour to 4 hours after entering the intensive care unit.(i.e. 2*15=30 points per one patient)

Anesthetic or post operative management were at the discretion of the attending anesthesiologist.
Data collection period: 24 hours later from data collection start at the operative room or 4 hours later from admission on ICU
