Why the study?
Does volume expansion with hydroxyethyl starch affect stroke volume variation (SVV) and other hemodynamic parameters in patients undergoing off-pump coronary artery bypass grafting?
Does volume expansion with hydroxyethyl starch affect stroke volume variation (SVV) and other hemodynamic parameters in patients undergoing off-pump coronary artery bypass grafting?
Volume expansion during off-pump CABG significantly decreases stroke volume variation and increases cardiac index, suggesting SVV reflects preload changes.
Supports SVV-guided fluid management in off-pump CABG; confirms dynamic preload assessment in cardiac surgical patients.
