“…Currently we lack data focusing on the accuracy and trending abilities of this device during general anesthesia. Moreover, pulse contour analysis methods may be impacted by the administration of vasopressors [12][13][14] such as phenylephrine [15].…”

“…This device offers the possibility of a nearly beat-to-beat measurement of CO and stroke volume variation (SVV). The accuracy of this device to assess CO and SVV has been tested in numerous settings with various results [6][7][8][9][10]. We have reported that SVV shown by the system can predict fluid responsiveness in patients undergoing one-lung ventilation (OLV) with acceptable levels of sensitivity and specificity [11].…”

We designed this study to determine the predictive value for fluid responsiveness of stroke volume variation (SVV) in patients undergoing one-lung ventilation (OLV), ventilated at different tidal volumes. All patients scheduled for pulmonary lobectomy were randomized into two groups according to their tidal volume [group H: tidal volume 8 ml/kg (n = 36); group L: tidal volume 6 ml/kg (n = 37)]. After starting OLV, volume loading was performed by administration of 500 ml 6% hydroxyethylated starch for 30 min. Hemodynamic variables were measured before and after volume loading using the Vigileo-FloTrac system. Patients in both groups were divided into fluid responders and non-responders, and responders were defined as those who demonstrated an increase in cardiac index ≥15% after volume expansion. The area under the receiver operating characteristic curve for SVV to discriminate between responders and non-responders was 0.776 in group H and 0.648 in group L. The optimal threshold value of SVV was 10.5% (sensitivity, 85.7%; specificity, 66.7%) in group H and 8% (sensitivity, 69.5%; specificity, 64.3%) in group L. We found that SVV could predict fluid responsiveness in patients undergoing OLV with acceptable levels of sensitivity and specificity only when tidal volume is at least 8 ml/kg.

“…de Waal and colleagues also compared ITD and FloTrac and found a percentage error of 33% [26]. Lorsomradee et al compared FloTrac with continuous thermo dilution method (CCO) and found that pulse contour analysis was able to reflect CO measured with CCO technique in patients undergoing uncomplicated CABG [27]. However, the pulse contour was less reliable in some situations like during sternotomy and phenylephrine administration.…”

Objective: The purpose of this study was to determine the correlation between cardiac index (CI) measurements made using intermittent thermodilution (ITD) technique by pulmonary artery catheter (PAC) and arterial pulse-contour analysis by FloTrac.Design: Prospective observational study. Setting:Cardiac surgery unit in a 350 bedded tertiary care hospital in India. Participants: 31 adult patients undergoing elective off-pump coronary artery bypass grafting (OPCABG) Interventions: CI measurements performed by the two different methods at six time points during the surgery (before skin incision, during grafting of left anterior descending artery, obtuse marginal artery and right coronary/ posterior descending artery, after protamine administration and after shifting the patient to recovery room). Measurements and results:The techniques a weak correlation at all six time points during the OPCABG. The mean bias of 0.85 L/min/m2 and precision of 0.55 was found in the study population. The percentage error calculated using Critchley s criteria was found to be 46%. Conclusion:CI measurements obtained using FloTrac showed a limited correlation with those acquired by ITD technique at different stages of OPCABG. Further studies are required in other patient populations and clinical situations.
