Effect of SVV-guided Fluid Therapy on Outcomes After Major Abdominal Surgery

Perioperative fluid management has been recognized as an important factor with an impact on postoperative recovery following major abdominal surgery. However, the optimal fluid management is difficult to achieve using standard parameters (e.g., heart rate \[HR\], blood pressure \[BP\], central venous pressure\[CVP\], or urine output) that poorly estimate preload and preload responsiveness. Goal-directed fluid therapy (GDFT) was proposed by introducing different hemodynamic variables into a dynamic perspective of individual fluid loading with or without vasoactive substances to reach predefined goal of optimal preload and/or oxygen delivery.There have been increasing numbers of studies evaluating the effect of perioperative GDFT on postoperative recovery following major abdominal surgery. However, the evidence for the beneficial effect of GDFT on postoperative recovery remains inconsistent.
