- Primary Outcome Measures
Name Time Method 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 Outcome Measures
Name Time Method 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.
