Perioperative fluid management is significant important during surgery. The current trend tends to use goal-directed fluid therapy in surgery. Goal-directed fluid therapy refers to continuous monitoring of hemodynamic parameters during surgery and managing more accurate fluid administration based on the data obtained while promoting optimal tissue perfusion. Define fluid responsiveness with the hemodynamic parameters as to whether the cardiac output can be significantly increased after administration of fluid. Therefore, the advantage of predicting fluid responsiveness is that it can optimize the cardiac output and tissue perfusion while avoiding administering unnecessary fluid to patients.~The purpose of this study is to evaluate whether the change of stroke volume index(△SVI) induced by the rapid mini-fluid administration can predict fluid responsiveness in patients with pneumoperitoneum.
