Hemodynamic Response During Goal Directed Fluid Therapy in the OR

Correlation of Multiple Invasive and Non-Invasive Hemodynamic Monitored Modalities to Support Goal Directed Fluid Therapy During Open Abdominal Surgery

The purpose of this study is to retrospectively evaluate the hemodynamic response to goal directed fluid therapy fluid during open abdominal surgery where goal directed fluid therapy is a standard of care after establishing a pre-incision baseline response to fluids.
