Continuous central venous oxygen saturation assisted intraoperative hemodynamic management during major abdominal surgery: A randomized, controlled trial

Major abdominal surgery is associated with significant risk of morbidity and mortality in the perioperative period. Optimising intraoperative fluid administration may result in improved outcomes. Our aim was to compare the effects of central venous pressure (CVP), and central venous oxygen saturation (ScvO2)-assisted fluid therapy on postoperative complications in patients undergoing high risk surgery.
