N2 - BACKGROUND: The purpose of this study was to determine the effects of transient arterial blood pressure change on the accuracy of the FloTrac™/Vigileo™ monitor (Edwards Lifesciences, Irvine, CA). METHODS: We compared stroke volume determined with the FloTrac/Vigileo with Doppler during anesthetic induction in 20 patients undergoing abdominal aortic reconstruction. RESULTS: The difference between the FloTrac measurements of stroke volume and the Doppler measurements of stroke volume was -7.5 ± 20.5 mL (mean ± SD) before induction, 0.3 ± 14.9 before laryngoscopy, 17.5 ± 26.9 during laryngoscopy, 20.5 ± 27.6, and -4.5 ± 16.4 mL 3 minutes after endotracheal tube placement. CONCLUSION: The FloTrac/Vigileo measured stroke volume with reasonable accuracy during transient hypotension but overestimated stroke volume during transient hypertension.
