Evaluate the feasibility and quality of automated anesthesia, analgesia and fluid management based on a combination of several physiological variables (bispectral index \[BIS\], stroke volume \[SV\], and stroke volume variation \[SVV\]) using 2 independent physiologic closed-loop systems (PCLS) in patients undergoing high risk vascular surgery

The percentage of adequate anesthesia defined as a BIS between between 40 and 60, a SVV < 13% and/or cardiac index > 2.5 litre/min/m² for more/equal of 85% of the surgical time
Timeframe: at time of surgery
