Perioperative Hemodynamic Optimization in High-Risk Patients Using Less-Invasive Monitoring Methods

The aim of this study is to evaluate different strategies of hemodynamic optimization in high risk surgical patients during the first twelve postoperative hours in ICU based on a protocol guided by a less invasive monitorig tool (Vigileo®), oriented by a fiberoptic central venous catheter that allows continuous monitorig of SvcO2 (PreSep®), and a pressure transducer (FloTrac®) that allows cardiac output calculation by the standard deviation of mean arterial pressure or a standard resuscitation strategy.
