NCT01950845

Brief Summary

Dynamic parameters like pulse pressure variation have been shown to be accurate predictors of fluid responsiveness. Hemodynamic optimization based on fluid management and stroke volume optimization have been shown to improve patient outcomes, especially for moderate and high risk abdominal surgical patients. A novel closed-loop fluid administration system based on multi-parameter hemodynamic monitoring have been described recently. This prospective, randomized, surgeon and patient blinded study aims at comparing the cardiac output provided by either this closed-loop system or the anesthesiologist team in high-rish surgical patient elected for abdominal surgery at Pierre Bénite University Hospital, Hospices Civils of Lyon, France. Primary endpoint is the mean indexed cardiac output during surgery per group. We will also compare hemodynamic parameter (cardiac output, stroke volume, blood pressure heart rate…) and patient's outcomes (morbidity, mortality, transfusion rate, hospital length of stay) between groups

Study Arms (2)

Automated fluid management system (Closed-loop system)

EXPERIMENTAL

cardiac output Vigileo® (Edwards Lifesciences) monitoring is connected to the closed loop system that will automatically provide per operative fluid bolus to optimize cardiac output by automated detection of fluid responsiveness state.

Device: Closed loop automated System (LIR®: learning intravenous resuscitator)

Current practice manual fluid management

SHAM COMPARATOR

cardiac output Vigileo® (Edwards Lifesciences) monitoring will be used to help the anesthesiologist team to detect fluid responsiveness state for the manual fluid management optimization

Device: manual current practice by anesthesiologist team

Interventions

The anesthesiologist team will manage the fluid administration during all the anesthesia procedure.

Current practice manual fluid management

Connection of the system to the patient under supervision of the anesthesiologist team during all the anesthesia procedure, respective of the applicability criteria for the fluid responsiveness detection.

Automated fluid management system (Closed-loop system)
