BACKGROUND: The goal of this study was to compare stroke volume variation (SVV) assessed from a peripheral artery with the VigileoTM/FloTracTM system (SVV-FloTrac) with SVV derived close to the heart by aortic Doppler (SVV-Doppler).

METHODS: Thirty patients undergoing liver transplantation underwent simultaneous SVV-FloTrac and SVV-Doppler measurements before and after intravascular volume expansion.

RESULTS: SVV-FloTrac and SVV-Doppler comparison before intravascular volume expansion showed a mean bias of 0.7%, and 95% limits of agreement of –4.2% to 5.5%. The areas under the receiver operating characteristic curves generated to discriminate responders and nonresponders to intravascular volume expansion were not different for SVV-FloTrac and SVV-Doppler.

CONCLUSIONS: SVV-FloTrac and SVV-Doppler measurements show acceptable bias and limits of agreement, and similar performance in terms of fluid responsiveness in patients undergoing liver transplantation.
