Clinical Trial Summary

Rivers et al. laid the foundation for modern hemodynamic and fluid management by establishing goal directed therapy (GDT) for the treatment of sepsis using fluid and inotropic and vasoactive agents. There have been many subsequent protocols to improve outcome in the operating room or in the ICU. These are mainly passive decision support systems. Active clinical decision support systems using fluid and pharmacologic agents to improve intraoperative hemodynamics are not really found.

The investigators developed an active clinical decision support system based on an institutional GDT-protocol using fluid, vasopressors and inotropes using the LiDCOrapid device.

The goal of the study was to check the feasibility of an active clinical decision support system to optimize hemodynamics during high risk vascular surgery based on the principles of GDT implementing fluid, vasopressors and inotropes.

Study Design


Intervention

Other:
active decision support system
The active decision support system in this study is a goal directed therapy (GDT) protocol where threshold hemodynamic values are defined when to give fluid, vasopressors and inotropes. Hemodynamic values are measured with the LiDCOrapid device, which uses pulse contour analysis to continuously monitor cardiac output and respiratory variations in stroke volume (SVV).
