Does the FloTrac/Vigileo system accurately measure cardiac output compared to a pulmonary artery catheter in patients undergoing off-pump coronary bypass surgery with reduced LVEF?

Population

50 patients (30 with LVEF ≥ 40%, 20 with LVEF < 40%) scheduled for elective, isolated, multivessel off-pump coronary bypass surgery (OPCAB). Excluded: preexisting pulmonary disease, concomitant valvular heart disease, cardiac arrhythmias, and peripheral vascular disease.

Intervention

Continuous cardiac index measurement using the uncalibrated pulse contour FloTrac/Vigileo™ system (FCI).

Comparator

Continuous cardiac index measurement using a pulmonary artery catheter (CCI).

Outcome

Agreement between FCI and CCI assessed by bias, limit of agreement, and percentage error at various intraoperative time points.surrogate

The FloTrac/Vigileo system provides reliable cardiac output measurements during off-pump coronary bypass surgery, even in patients with reduced LVEF, provided systemic vascular resistance is within normal limits.

Limitations

The FCI was compared to the CCI and not with the cardiac index measured by intermittent PAC thermodilution.
