IDVG monitor

BACKGROUND: The pleth variability index (PVI) has been demonstrated to be a useful, noninvasive indicator of continuous fluid responsiveness. Whether PVI can be used to assess the changes of intravascular volume status remains to be elucidated. MATERIAL AND METHODS: Using correlation analysis and receiver operating characteristic (ROC) curves, we sought a correlation between PVI and the initial distribution volume of glucose (IDVG), evaluating PVI as an indicator of the central extracellular fluid volume after anesthesia induction in patients undergoing elective abdominal surgery...

PURPOSE: Recognition of intraoperative hypovolemia is important for fluid management. Previous studies demonstrated functional preload parameter pulse pressure variation (PPV) could predict volume changes in response to fluid loading and loss. In this study, we examined the correlation between PPV and other two cardiac preload indicators, central venous pressure (CVP) or initial distribution volume of glucose (IDVG), in patients after anesthesia induction. METHODS: In 30 patients undergoing scheduled craniotomy surgery, we compared measurement of PPV (%) using the Ohmeda monitor method to simultaneously measure CVP and IDVG after anesthesia induction through correlation analysis and receiver operating characteristic (ROC) curves...

OBJECTIVES: To determine whether the initial distribution volume of glucose (IDVG) rather than plasma volume or blood volume is correlated better with cardiac output during the 4 days following major surgery. DESIGN AND SETTING: Prospective clinical investigation in the general intensive care unit of a university hospital. PATIENTS AND METHODS: 31 consecutive patients who underwent radical surgery for esophageal carcinoma were enrolled. Continuous thermodilution cardiac output monitor was placed in the operating room...
