Caution advised against FloTrac for cardiac index in off-pump CABG; hypothesis-generating for validation against thermodilution.
Does arterial pulse-contour analysis by FloTrac accurately estimate cardiac index compared to intermittent thermodilution in adult patients undergoing elective off-pump coronary artery bypass grafting?
FloTrac-derived cardiac index measurements showed limited correlation and high percentage error compared to intermittent thermodilution during off-pump CABG, suggesting it may not be a reliable alternative in this setting.
