Abstract

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.

摘要

背景

本研究旨在确定瞬态动脉血压变化对 FloTrac/Vigileo 监护仪（爱德华生命科学公司，欧文，加利福尼亚州）准确性的影响。

方法

我们比较了在 20 例行腹主动脉重建的患者麻醉诱导期间，通过 FloTrac/Vigileo 和多普勒确定的每搏量。

结果

在诱导前，FloTrac 测量的每搏量与多普勒测量的每搏量之间的差异为-7.5 ± 20.5 毫升（平均值 ± 标准差），在喉镜检查前为 0.3 ± 14.9 毫升，在喉镜检查期间为 17.5 ± 26.9 毫升，在气管内导管放置后 3 分钟时为 20.5 ± 27.6 毫升和-4.5 ± 16.4 毫升。
