Why the study?
Do dynamic volume parameters (GEDVI, SVV, PPV) better predict changes in cardiac index and stroke volume index compared to filling pressures (CVP, PCWP) in patients undergoing coronary artery bypass surgery?
Population
40 patients undergoing coronary artery bypass surgery, mean age 63, 90% male, in Germany.
Design
Cohort
Follow-up
15 minutes after sternotomy

Dynamic parameters may better track cardiac index than filling pressures in open-chest CABG; hypothesis-generating, requiring RCTs before guiding therapy.
Do dynamic volume parameters (GEDVI, SVV, PPV) better predict changes in cardiac index and stroke volume index compared to filling pressures (CVP, PCWP) in patients undergoing coronary artery bypass surgery?
Dynamic volume parameters (GEDVI, SVV, PPV) are superior to conventional filling pressures (CVP, PCWP) for predicting volume responsiveness in cardiac surgery patients under open-chest conditions.
