  Purpose

"The impact on fluid loading after cardiac surgery by use of two different priming solution"

Fluid overloading with oedema formation is a regular finding following on-pump cardiac surgery and may contribute to postoperative organ dysfunction. Myocardial oedema has been reported to impair both systolic and diastolic function. An association between intraoperative fluid loading and postoperative adverse outcome has been demonstrated in cardiac patients.

The investigators have experience with the use of both colloides and combination fluids (hypertonic saline/colloides) in several experimental studies (pigs). In one animal study the investigators used colloides as an additive to the CPB-prime. The investigators observed reduced fluid leakage and less total tissue water in several organs.

The planned study includes patients scheduled for coronary artery bypass, and who have no co-morbidity. The patients will be randomized to receive either Tetraspan® (HES) or acetated Ringer`s solution in the CPB-prime. Accurate accounts of fluid additions, blood loss and diuresis will be kept. Determination of cardiac output (C.O.), intrathoracic blood volume (ITBV), extravascular lung water (EVLW) and global end diastolic volume (GEDV) will be monitored by use of the transpulmonary thermodilution technique PiCCO®plus system.

Primary Outcome Measures:
  • Reduction of organ edema and improved organ function [ Time Frame: 6-hours postoperatively ] [ Designated as safety issue: No ]
    As a target of effect the investigators have chosen to study improvements for organ function.Indexed values for cardiac output(CI) measured by the PICCO system will be a parameter for heart function, andf lung function will be measured by EVLWI(extravascular lungwater index).paO2/FiO2-ratio and time spent in respirator.Additionally a strict account for fluid balance will be kept.
