NCT01470976

Brief Summary

The primary aim of the study is to investigate whether a goal-directed resuscitation therapy in high-risk patients through cardiac index optimization using the LiDCO Rapid device reduces complications after cardiac surgery. The hypothesis is that there are better outcomes when achieving a cardiac index higher than 3L/min/m2 in those patients with an arterial lactate higher than 1.5 mmol/L.

Standard Protocol

ACTIVE COMPARATOR
Other: Standard protocol

Interventions

* A target value of a cardiac index (CI) greater than 3.0 L/min/m2 will be sought. * The first step will be fluid resuscitation with 250ml aliquots of Lactated Ringer's solution whenever the CI is lower than 3,0 L/min/m2 and systolic volume index (SVI) is lower than 35ml/m2. The fluid challenge will be stopped if the CVP rises by more than 4 mmHg during the infusion period. * When the CI is lower than or equal to 3,0L/min/m2 and SVI higher than or equal to 35 ml/m2, dobutamine will be initiated with increasing doses up to 20mcg/kg/min. * The final step will be red blood transfusion to reach a hematocrit higher than 28%.

Also known as: LiDCO Rapid will be used to calculate CI and SVI.
Goal-directed Therapy (GDT) Protocol

The control group will be managed by the anesthetic team in the operative room and by the surgical ICU staff in the postoperative period according to institutional protocol of hemodynamic monitoring.
