Fluid Optimization in Liver Surgery

Study on Fluid Optimization in Liver Surgery Trough Vigileo/FloTac System Associated to Traditional Monitoring.

The purpose of this study is to analyze hemodynamic changes, in patients undergoing liver resection, through the Vigileo/FloTrac system.

To reduce bleeding, hepatectomies are performed with low central pressure (CVP) combined with extrahepatic control flow.

This management can lead hemodynamic instability and reduction in oxygen delivery so an advanced monitoring should be used.

This study analyzes hemodynamic changes, in patients undergoing liver resection, through the Vigileo/FloTrac system.
