Acute microcirculatory perfusion disturbances is common in critical illness and associated with higher morbidity and mortality. Recent findings by the investigators' group showed that microcirculatory perfusion is disturbed during cardiac surgery with cardiopulmonary bypass (CPB) and remain disturbed up to 72 (seventy two) hours after surgery. A cardiopulmonary bypass is a machine which takes over heart and lung function, during the procedure. The disturbed microcirculation is associated with organ dysfunction induced by cardiac surgery using CPB, which is frequently seen (up to 42%, forty two percent) and results in a six-fold increase in mortality rate. The underlying cause of disturbed microcirculation is a higher endothelial permeability and vascular leakage and are a consequence of systemic inflammation, hemodilution (dilution of blood), hypothermia and hemolysis (breakdown of red blood cells). To gain the knowledge regarding disturbed microcirculation the investigators previously showed that hemodilution attributes to this disturbed perfusion. Hemodilution lowers colloid oncotic pressure (COP). Also, COP is affected by free hemoglobin, which increases with hemolysis and attributes to a disturbed microcirculation following CPB. This is interesting, as to the best of our knowledge, the effect of minimizing hemodilution and hemolysis during cardiac surgery on the microcirculatory perfusion has never been investigated, but could be the key factor in reducing organ dysfunction.
Researchers from the University of Michigan and Northwestern University are studying people's experiences with swelling caused by Nephrotic Syndrome. Interviews with patients (child and adult) and parents of young children will be conducted. The information collected from the interviews will be used to develop a survey to use when testing new medications for Nephrotic Syndrome. Please consider participating in a 1-hour long interview with the Prepare-NS research study to discuss children and adults experiences with swelling.
To determine the feasibility and safety of deresuscitation using slow continuous ultrafiltration with regional citrate anticoagulation and peripheral or standard central venous access.
Critically ill patients with acute kidney injury and fluid overload who are frequently treated by fluid removal during dialysis are at an increased risk of complications and death. Both slower and faster rates of fluid removal may cause injury to the vital organs. This proposed clinical trial will examine the feasibility of restrictive compared with a liberal rate of fluid removal in order to develop effective treatments for fluid overload and to improve the health of critically ill patients.
This prospective cohort study aim to investigate the ability of multiple types of assessments including 1) the modified Venous Excess Ultrasound (VExUS) assessment, 2) non-invasive estimation of absolute blood volume (ABV), and 3) change in carotid Doppler at the start of IKRT to predict IDHE in acutely ill hospitalized patients. The secondary aim will be to determine whether each modality improves the prediction of IHDE compared to the evaluation of the attending physician and whether they also predict cerebral hypoxia during IKRT measured by near-infrared spectroscopy (NIRS). Finally, detailed hemodynamic data including relative blood volume monitoring, tissue oximetry, and other parameters will be collected continuously during IKRT sessions enabling exploratory analyses aimed at identifying hemodynamic phenotypes related to IDHE during IKRT.
The purpose of this study is to investigate the ability of changes in PPV and SVV after Tidal Volume Challenge to predict fluid responsiveness in patients undergoing general anesthesia with protective mechanical ventilation.
A quasi experimental study that aims to verify whether the incorporation of VExUS in patients with AKI in the Intensive Care Unit (ICU) may prompt tailored interventions to increases the number of days free from Renal Replacement Therapy (RRT) during the first 28 days.
Timely recognition and treatment of fluid overload can expedite liberation from invasive mechanical ventilation in intensive care unit (ICU) patients. Lung ultrasound (LUS) is an easy to learn, safe, cheap and noninvasive bedside imaging tool with high accuracy for pulmonary edema and pleural effusions in ICU patients. The aim of this study is to assess the effect of LUS-guided deresuscitation on duration of invasive ventilation in ICU patients. The investigators hypothesize that LUS-guided fluid deresuscitation is superior to routine fluid deresuscitation (not using LUS) with regard to duration of invasive ventilation. This study is a national multicenter randomized clinical trial (RCT) in invasively ventilated ICU patients.This study will include 1,000 consecutively admitted invasively ventilated adult ICU patients, who are expected not to be extubated within the next 24 hours after randomization. Patients are randomly assigned to the intervention group, in which fluid deresuscitation is guided by repeated LUS, or the control group, in which fluid deresuscitation is at the discretion of the treating physician (not using LUS).
Fluid overload is a poor prognostic factor in patients undergoing continuous renal replacement therapy in critical care. A strategy of active fluid removal by net ultrafiltration (UFnet) is one of the means to correct it. However, fluid overload is difficult to quantify: weight variations or cumulative fluid balance are easy to use but imprecise and not concordant markers, while reference methods such as isotope dilution are not adapted to daily practice. Bio electrical impedance analysis (BIA) is used to estimate body composition, including hydration. It is a non-invasive, rapid and painless measurement. It is commonly used in chronic intermittent haemodialysis to estimate dry weight and guide fluid removal, with a demonstrated impact on blood pressure control. This analysis is feasible in the ICU. Fluid overload as defined by BIA correlates with mortality, most notably in acute renal failure and during continuous renal replacement therapy. We routinely perform multifrequency segmental BIA (InBody S10, Seoul, Korea) in patients with fluid overload in our intensive care department. Since February 2021, we have implemented a protocol to systematically correct fluid overload by inducing negative fluid balance with UFnet in a manner appropriate to tissue perfusion. In this context, we systematically perform a BIA analysis on the day of the beginning of the fluid balance negativation and then every 48 hours during the first five days. We would like to evaluate the relevance of BIA monitoring in these patients by comparing it to other parameters of evaluation of the volume status usually used.
