PURPOSE OF REVIEW: To evaluate the existing evidence on the passive leg raising (PLR) test for fluid responsiveness prediction. RECENT FINDINGS: It has been well established that either insufficient or excessive fluid administration derives in worse outcomes in critically ill patients, highlighting that a more accurate assessment of fluid management is required. Accordingly, several cardiovascular indices have been tested to improve our ability to predict patients' response to fluid loading at the bedside, the so-called functional hemodynamic monitoring...

The determination of fluid responsiveness in the critically ill child is of vital importance, more so as fluid overload becomes increasingly associated with worse outcomes. Dynamic markers of volume responsiveness have shown some promise in the pediatric population, but more research is needed before they can be adopted for widespread use. Our aim was to investigate effectiveness of respiratory variation in peak aortic velocity and pulse pressure variation to predict fluid responsiveness, and determine their optimal cutoff values...

BACKGROUND: A relatively new uncalibrated arterial pressure waveform cardiac output (CO) measurement technique is the Pulsioflex-ProAQT® system. Aim of this study was to validate this system in cardiac surgery patients with a specific focus on the evaluation of a difference in the radial versus the femoral arterial access, the value of the auto-calibration modus and the ability to show fluid-induced changes. METHODS: In twenty-five patients scheduled for ascending aorta, aortic arch replacement, or both we measured CO simultaneously by transpulmonary thermodilution (COtd) and by using the ProAQT® system connected to the radial (COpR), as well as the femoral artery catheter (COpF)...

OBJECTIVE: Evaluate the dose-response relationship between intraoperative fluid administration and postoperative outcomes in a large cohort of surgical patients. BACKGROUND: Healthy humans may live in a state of fluid responsiveness without the need for fluid supplementation. Goal-directed protocols driven by such measures are limited in their ability to define the optimal fluid state during surgery. METHODS: This analysis of data on file included 92,094 adult patients undergoing noncardiac surgery with endotracheal intubation between 2007 and 2014 at an academic tertiary care hospital and two affiliated community hospitals...

BACKGROUND: Fluid therapy is a common and crucial treatment in the emergency department (ED). While fluid responsiveness seems to be a promising method to titrate fluid therapy, the evidence for its value in ED is unclear. We aim to synthesise the existing literature investigating fluid responsiveness in ED. METHODS: MEDLINE, Embase and the Cochrane library were searched for relevant peer-reviewed studies published from 1946 to present. RESULTS: A total of 249 publications were retrieved of which 22 studies underwent full-text review and eight relevant studies were identified...

To assess the significance of an analogue of the mean systemic filling pressure (Pmsa) and its derived variables, in providing a physiology based discrimination between responders and non-responders to fluid resuscitation during liver surgery. A post-hoc analysis of data from 30 patients undergoing major hepatic surgery was performed. Patients received 15 ml kg(-1) fluid in 30 min. Fluid responsiveness (FR) was defined as an increase of 20% or greater in cardiac index, measured by FloTrac-Vigileo(®). Dynamic preload variables (pulse pressure variation and stroke volume variation: PPV, SVV) were recorded additionally...

OBJECTIVE: Fluid infusion, the most critical step in the resuscitation of patients with septic shock, needs preferably continuous invasive hemodynamic monitoring. The study was planned to evaluate the efficacy of ultrasonographically measured inferior vena cava collapsibility index (IVC CI) in comparison to central venous pressure (CVP) in predicting fluid responsiveness in septic shock. MATERIALS AND METHODS: Thirty-six patients of septic shock requiring ventilatory support (invasive/noninvasive) were included...

A novel methodology for accurate fluid characterization from multi-dimensional nuclear magnetic resonance (NMR) well-logging measurements is introduced. This methodology overcomes a fundamental challenge of poor resolution of features in multi-dimensional NMR distributions due to low signal-to-noise ratio (SNR) of well-logging measurements. Based on an unsupervised machine-learning concept of blind source separation, the methodology resolves fluid responses from simultaneous analysis of large quantities of well-logging data...

Fluid administration is a powerful tool for hemodynamic stabilization as it increases preload and improves cardiac function in fluid-responsive patients. However, there are various types of fluid to choose from. The use of colloids and crystalloids in non-cardiac Intensive Care Units (ICU) has been reported, showing controversial results. Many trials on sepsis in a non-cardiac ICU setting show that colloids, in particular hydroxyethyl starches and gelatins, might have a detrimental effect on kidney function, and on major outcomes such as mortality...

BACKGROUND: Fluid resuscitation is considered a cornerstone of shock treatment, but recent data have underlined the potential hazards of fluid overload. The passive leg raise (PLR) test has been introduced as one of many strategies to predict 'fluid responsiveness.' The use of PLR testing is applicable to a wide range of clinical situations and has the potential to reduce fluid administration, since PLR testing is based upon (reversible) autotransfusion. Despite these theoretical advantages, data on the net effect on fluid balance as a result of PLR testing remain scarce...

BACKGROUND: Functional imaging by thoracic electrical impedance tomography (EIT) is a non-invasive approach to continuously assess central stroke volume variation (SVV) for guiding fluid therapy. The early available data were from healthy lungs without injury-related changes in thoracic impedance as a potentially influencing factor. The aim of this study was to evaluate SVV measured by EIT (SVVEIT) against SVV from pulse contour analysis (SVVPC) in an experimental animal model of acute lung injury at different lung volumes...
