The aim of this study was to compare the prediction of fluid responsiveness  using the stroke volume variation (SVV) determined by FloTrac™ (SVV-FloTrac; Edwards Lifesciences, USA) and PiCCOplus™ (SVV-PiCCO; Pulsion Medical Systems, Germany).
With ethics committee approval, the SVV-FloTrac, SVV-PiCCO, pulse pressure variation (PPV), global end-diastolic volume (GEDV) and stroke volume (SV) were measured before and after a volume shift induced by body positioning (30° head-up to 30° head-down) in 40 patients after cardiac surgery. A t test, Bland–Altman analysis, Pearson correlation and area under the receiver operating curves (AUC) were calculated. P < 0.05 was considered significant.
AUC predicting ΔSV > 25% and Pearson correlation of baseline indices versus ΔSV
SVV-FloTrac and SVV-PiCCO showed a comparable performance in predicting fluid responsiveness. When compared with SVV-PiCCO, a lower threshold value for SVV-FloTrac has to be considered.
