Accuracy and trending ability of the fourth-generation FloTrac/Vigileo System™ in patients undergoing abdominal aortic aneurysm surgery

Abstract

Purpose

The fourth-generation FloTrac/Vigileo™ improved its algorithm to follow changes in systemic vascular resistance index (SVRI). This revision may improve the accuracy and trending ability of CI even in patients who undergo abdominal aortic aneurysm (AAA) surgery which cause drastic change of SVRI by aortic clamping. The purpose of this study is to elucidate the accuracy and trending ability of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery by comparing the FloTrac/Vigileo™-derived CI (CI_FT) with that measured by three-dimensional echocardiography (CI_3D).

Methods

Twenty-six patients undergoing elective AAA surgery were included in this study. CI_FT and CI3_D were determined simultaneously in eight points including before and after aortic clamp. We used CI_3D as the reference method.

Results

In the Bland–Altman analysis, CI_FT had a wide limit of agreement with CI_3D showing a percentage error of 46.7%. Subgroup analysis showed that the percentage error between CO_3D and CO_FT was 56.3% in patients with cardiac index < 2.5 L/min/m² and 28.4% in patients with cardiac index ≥ 2.5 L/min/m². SVRI was significantly higher in patients with cardiac index < 2.5 L/min/m² (1703 ± 330 vs. 2757 ± 798; p < 0.001). The tracking ability of fourth generation of FloTrac/Vigileo™ after aortic clamp was not clinically acceptable (26.9%).

Conclusions

The degree of accuracy of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery was not acceptable. The tracking ability of the fourth-generation FloTrac/Vigileo™ after aortic clamp was below the acceptable limit.

S16-2. Strategy in anesthetic management for intraoperative neuromonitoring

The development of postoperative functional dysfunction can have an impact on the length of hospital stay, total medical costs, and necessity of dependency. To maintain functional integrity, neuromonitoring including motor evoked potential (MEP), sensory evoked potential, and visual evoked potential, has been conducted during the operation. Anesthetic management is usually based on the maintenance of MEP, which is most susceptible to suppression by anesthetic agents. MEP is indicated for craniotomy, spine surgery and aortic surgery, in which the technique for stimulation and recording can vary on types of surgery.
