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 (CIFT ) with that measured by three-dimensional echocardiography (CI3D )...

OBJECTIVES: Haemodynamic monitoring during post arrest care is important to optimise treatment. We compared stroke volume measured by minimally-invasive monitoring devices with or without thermodilution calibration, and transthoracic echocardiography (TTE), and hypothesised that thermodilution calibration would give stroke volume index (SVI) more in agreement with TTE during targeted temperature management (TTM). DESIGN: Comatose out-of-hospital cardiac arrest survivors receiving TTM (33 °C for 24 hrs) underwent haemodynamic monitoring with arterial pulse contour analyses with (PiCCO2®) and without (FloTrac® /Vigileo® monitor® ) transpulmonary thermodilution calibration...

BACKGROUND: Patients with liver cirrhosis undergoing liver transplantation have a hyperdynamic circulation which persists into the early postoperative period making accurate assessment of fluid requirements challenging. Goal-directed fluid therapy (GDFT) has been shown to reduce morbidity and mortality in a number of surgery settings. The impact of GDFT in patients undergoing liver transplantation is unknown. A feasibility trial was designed to determine patient and clinician support for recruitment into a randomised controlled trial of GDFT following liver transplantation, adherence to a GDFT protocol, participant withdrawal, and to determine appropriate endpoints for a subsequent larger trial to evaluate the efficacy of GDFT in patients undergoing liver transplantation...

Blood pressure (BP), a surrogate of cardiac output (CO), is also dependent on systemic vascular resistance (SVR). But SVR is not routinely monitored in daily clinical practice. We hypothesise that the time difference between the peripheral arterial waveform and the finger plethysmographic waveform (time lag index - TLi) could indicate the systemic vascular resistance. In this study, we correlated TLi with the systemic vascular resistance measured by minimally invasive CO monitor (pulse contour analysis). SVR changes in response to administration of mannitol were studied...

BACKGROUNDS: Perioperative fluid-therapy is a still a debated issue. In hepatic surgery, volume load must be strictly monitored to assure both a safe hemodynamics and low central venous pressure (CVP) to limit the backflow bleeding. Retrospectively, we compared intraoperative fluid management before and after the adoption of a semi-invasive hemodynamic monitoring. METHODS: We compared patients submitted to liver resection monitored by FloTrac/VigileoTM (group A) vs...

The FloTrac system is a system for cardiac output (CO) measurement that is less invasive than the pulmonary artery catheter (PAC). The purposes of this study were to (1) compare the level of agreement and trending abilities of CO values measured using the fourth version of the FloTrac system (CCO-FloTrac) and PAC-originated continuous thermodilution (CCO-PAC) and (2) analyze the inadequate CO-discriminating ability of the FloTrac system before and after cardiopulmonary bypass (CPB). Fifty patients were included...

INTRODUCTION: Dynamic arterial elastance (Eadyn) is defined as the ratio between pulse pressure variations (PPV) and stroke volume variations (SVV). Eadyn has been proposed to predict an increase in mean arterial pressure (MAP) after volume expansion with conflicting results. The aim of the present study was to test the reliability of Eadyn in hypotensive patients (MAP<65mmHg) in the operating room (OR). PATIENTS AND METHODS: The study pooled data from 51 patients...

BACKGROUND: There is a national shortage of organs available for transplantation, and utilization rates for thoracic organs are less than 40%. In addition, the optimal method of assessing cardiovascular status during donor management is uncertain. FloTrac is a noninvasive hemodynamic technique that measures cardiac output and fluid responsiveness. Our objective was to measure the impact of using this technique to guide management on fluid balance, vasopressor usage, thyroid hormone usage, and pulmonary function...
