Stroke Volume Variation vs Central Venous Pressure Guidance Fluid Management in Endovascular Aortic Repair

Hypothesis: Fluid management guided by stroke volume variation (SVV), compared with central venous pressure (CVP), guidance results in better clinical outcomes. Primary outcomes: Perioperative, up to 48 h postoperative, serum lactate and creatinine level. Methods: Adult patients undergoing endovascular aortic aneurysm repair (EVAR) will be randomized into 2 groups: SVV group managed by SVV guidance and CVP group managed by CVP guidance. Outcome analyses: Compare serum lactate, creatinine as well as other postoperative complications between both groups.
