Filter by:Volume expansion is the cornerstone of perioperative hemodynamic optimization. The main objective of volume expansion is to increase and maximize stroke volume. Hemodynamic changes have an impact on the autonomic nervous system. The analysis of heart rate variability allows an exploration of the autonomic nervous system and could therefore provide information on the effect of volume expansion. The Analgesia Nociception Index (ANI) is an analgesia monitor based on the concept of heart rate variability. By deviating from its original use, the investigators wish to evaluate the ability of ANI to identify a response to volume expansion.
The Pressure Recording Analytical Method, invasive hemodynamic monitoring, is an uncalibrated pulse contour analysis, installed in the Mostcare® system that allows a continuous estimation of the stroke volume and thus the cardiac output, by the relationship between the area under the curve of the systolic portion of the arterial blood pressure curve and the dynamic impedance of the cardiovascular system. The objectives of the study are to determine if the parameters measured by Mostcare® make it possible to predict the response to volume expansion in pediatric surgical critical care patients, sedated, intubated and ventilated, by comparing the changes in stroke volume, induced by a volume expansion, measured by trans-thoracic echocardiography.
The aim of the study to examine Optic Nerve Sheath Diameter measurement for prediction of fluid responsiveness in hemodynamically unstable patients
The increased intraabdominal pressure and intrathoracic pressure due to pneumoperitoneum negatively affect the cardiovascular system, relatively dynamic parameters may vary due to intraoperative fluid therapy.
Surgical patients, especially those with insufficient blood volume and hypotension, often need fluid therapy. However, there is still a lack of simple and reliable indicators for judging transfusion responsiveness in some types of surgery. Previous studies have shown that Pressure Gradient for Venous Return (PVR) can be used to guide infusion. Thus, our aim is to explore the relationship between PVR and liquid reactivity.
To investigate whether PVI predicts the fluid responsiveness in modified prone position undergoing posterior approach cervical operation. Furthermore, modified prone position could influence on dynamic variables including stroke volume variation(SVV), pulse pressure variation(PPV) and PVI.
The aim of this study is to evaluate the diagnostic accuracy of electrical cardiometry (EC) for the noninvasive determination of fluid responsiveness in sepsis and agreement of (EC) compared to transthoracic echocardiography (TTE).
This study will be conducted to assess the role of end-tidal carbon dioxide (PETCO2) monitoring to predict the fluid volume responsiveness in correlation with stroke volume variation detected by electrical cardiometry in patients with hemodynamic instability.
Proper identification of patients who would benefit from fluid infusion (fluid responsiveness) is one of the most crucial challenges in anaesthesia and critical care. Reliability of several invasive measurements used for this purpose for many years have been questioned recently. The study will evaluate consistency between carotid artery flow derivatives and standard haemodynamic measurement (LIDCO rapid) in navigation of intraoperative fluid therapy.
The aim of the study is to evaluate whether changes in Perfusion Index (PI) and Pleth Variability Index (PVI) during passive leg raising test can predict fluid responsiveness in spontaneously breathing patients. Fluid responsive patients are defined as showing an increase in cardiac output >10% during a passive leg raising test, measured semi-invaseively with FloTrac® (Edwards LifeSciences. Irvine, United States).
