  Purpose

In this trial, the investigators intend to examine whether the concentration of local anesthetics during epidural analgesia could be modulating factor for change of hemodynamics in patients undergoing major upper abdominal surgery.

Primary Outcome Measures:
  • measure of hemodynamics [ Time Frame: during 1hour after administration of epidural drug dosing ] [ Designated as safety issue: Yes ]
    Systolic blood pressure, diastolic blood pressure, MAP, HR, stroke volume, stroke volume, stroke volume index, stroke volume variation, cardiac output, and cardiac index were continuously measured at 5 minute intervals during 1 hour.
