Hypothesis
The study aims to evaluate the concordance on stroke volume index changes obtained from calibrated and uncalibrated devices during postoperative hemodynamic optimization.
Conclusion
The LiDCO™plus and Vigileo™ devices identified the same direction of changes in stroke volume in 78% of cases during postoperative hemodynamic optimization.
Supporting Evidence
- The mean bias between LiDCO-SVI and Vigileo-SVI was 1.16 ml/m2.
- The two devices showed the same direction of changes in 78% of the cases.
- They agreed in 81% of cases to define responder and nonresponder.
Takeaway
Doctors used two different machines to check how well patients' hearts were doing after surgery, and they mostly agreed on the results.
Methodology
A prospective study comparing stroke volume index changes from two devices in surgical patients during early postoperative hemodynamic optimization.
Participant Demographics
Patients undergoing abdominal surgery.
Statistical Information
Confidence Interval
95% limit of agreement from -23.36 to 25.68 ml/m2
