fluid responders
Patients whose stroke volume index increase by >10% in response to a 500-ml fluid bolus was defined as fluid responders.
fluid non-responders
Patients whose stroke volume index increase by <10% in response to a 500-ml fluid bolus was defined as fluid non-responders.

Primary Outcome Measures :
  1. fluid responsiveness (mean artery pressure、cardiac output、stroke volume variation、internal jugular vein distensibility) [ Time Frame: after fluid challenge (30min) ]
    CO increased more than 10% was defined as fluid responsiveness
