Objective: Changes in stroke volume after fluid bolus infusion (i.e., fluid responsiveness) during major abdominal surgery is affected by painful stimuli, anesthetics and inconsistent increases in cardiac preload following each round of fluid infusion. This study aimed to assess the relationship between stroke volume variation (SVV) and stroke volume during major abdominal surgery using arterial pulse contour analysis by removing data of stroke volume affected by these factors. Methods: Eighty-three patients who underwent major abdominal surgery received 8 ml/kg boluses of either Ringer’s acetate or 6% hydroxyethyl starch 70/0.5 solution over the course of 30 minutes. Stroke volume index (SVI) and SVV were obtained using the FloTracTM/VigileoTM system (Version 3.02). Patients were classified according to values of absolute changes of SVV (ΔSVV, %) and relative changes of S.. View More»
