Goal-Directed Fluid Management Based on The Pulse Oximeter-Derived Pleth Variability Index
目标指导液体管理基于脉搏血氧计派生 脉搏灌注变异指数（PVI)
Reduces Lactate Levels and Improves Fluid Management. Methods
降低乳酸水平、提高液体管理。
Methods 方法
Eighty-two patients scheduled for major abdominal surgery were randomized into 2 groups to compare intraoperative PVI-directed fluid management (PVI group) versus standard care (control group)
After the induction of general anesthesia, the PVI group received a 500-mL crystalloid bolus and a crystalloid infusion of 2 mL • kg(-1) • h(-1).
全身麻醉诱导后，PVI组收到了500ml的晶体推注和 2ml/Kg/H 晶体液注输
Colloids of 250 mL were administered if the PVI was >13% Vasoactive drug support was given to maintain the mean arterial blood pressure above 65 mm Hg.
In the control group, an infusion of 500 mL of crystalloids was followed by fluid management on the basis of fluid challenges and their effects on mean arterial blood and central venous pressure.
在对照组中，500ml的晶体输液后的流体管理取决于液体的挑战和对平均动脉血和中心静脉压的影响。
Perioperative lactate levels, hemodynamic data, and postoperative complications were recorded prospectively.
