Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1: Patients who undergo hepatectomy as scheduled surgery (no provisions are made based on age, gender, target disease, or presence or absence of prior treatment) 2: Patients in whom a central venous catheter capable of CVP measurement is inserted and indwelled during surgery, and a Flo TracTM Sensor is connected to the arterial indwelling catheter so that SVV can be calculated. 3: Patients aged 20 years or older at the time of consent acquisition. 4: Patients who received sufficient explanation and fully understood when participating in this study, and obtained written consent by the patient himself / herself.

Exclusion criteria

Exclusion criteria: 1: Patients with unstable hemodynamics at the time of induction of anesthesia (shock index> 1) 2: Patients with severe aortic regurgitation or atrial fibrillation (because the analysis result by Flo TracTM Sensor becomes unstable) 3: Patients judged by the investigator to be inappropriate as subjects

Design outcomes

Primary

MeasureTime frame
With 0 degree as the reference value, evaluate the correlation between the rate of change of CVP and SVV due to intraoperative postural change (5 degree and 10 degree ) using linear regression analysis.

Secondary

MeasureTime frame
If the SVV value does not show a large change due to the postural change, the estimation of the CVP change rate in the SVV eigenvalue and the identification of the factors that influence the change due to the postural change of CVP / SVV are verified as secondary evaluation items. In the statistical analysis method, regarding the estimation of the CVP change rate in the SVV eigenvalue, the CVP change rate in the SVV value for each case is obtained, evaluated by performing linear regression analysis, and the factors that influence the fluctuation due to the position change of CVP / SVV. Identification is evaluated by performing multivariate analysis using preoperative information or information obtained during surgery as explanatory variables.
