NCT07484009
This clinical trial aims to determine whether a ReDS-guided treatment strategy is superior to the current standard of care for adults hospitalized with heart failure. Additionally, the study will evaluate the safety and cost-effectiveness of this approach. The study seeks to answer the following key questions: 1. Does the ReDS-guided strategy reduce the risk of cardiovascular events during the first month following hospital discharge? 2. What is the safety profile of this treatment strategy? Researchers will compare the ReDS-based strategy against the current standard of care. All participants will: * Undergo daily assessments using the ReDS device throughout their hospitalization. * Attend two follow-up visits post-discharge, scheduled at 2 weeks and 30 days.

Fluid overload, which is when your body has too much fluid, is one of the reasons why people on home dialysis need to go to the hospital. Fluid overload (when body has too much fluid) commonly presents as trouble breathing and leg swelling. Traditionally, doctors check for this by asking patients if they have any symptoms like leg swelling or shortness of breath and by doing a physical exam which includes listening to the lungs or looking for swelling in legs. However, a newer, safe, and non-invasive method called point-of-care ultrasound (POCUS) has become very popular. However, we don't have a lot of research yet on how POCUS and LUS (lung ultrasound) specifically help home dialysis patients, including those on peritoneal dialysis or home hemodialysis. Peritoneal dialysis is a way to clean your blood by putting a special fluid into your belly through a small tube. The fluid uses the natural lining of your belly as a filter to remove waste and extra water. Home hemodialysis is a treatment where a machine acts like an artificial kidney to clean your blood. You get trained to do this yourself at home by connecting to the machine with a couple of needles, which cleans your blood of waste and extra fluid. POCUS, especially a (LUS), has been shown to be useful for dialysis patients in outpatient units. This study will compare different 3 different methods of detecting fluid overload: answering various survey questions, completing a physical exam, and a LUS. The study seeks to determine which of these methods is the best method to determine fluid overload. You were selected as a possible participant because you are over 18 years old, diagnosed with End-stage kidney disease, and have been receiving home dialysis for at least three months.
NCT05505500
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.

NCT05647057
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.
NCT05869656
The aim of this feasibility study is to determine whether an alert embedded within the electronic health record (EHR) causes clinicians to enrol patients into a randomised controlled trial (RCT) comparing oral fluid restriction versus no restriction in patients admitted to hospital with fluid overload. One of the main causes of fluid overload is heart failure where there is a lack of strong evidence to support the effectiveness of oral fluid restriction in the acute setting. This causes significant variation in clinical practice where decisions on whether or not to impose a restriction in oral fluid intake is based on the preference of the treating clinician rather than robust evidence from research. THIRST Alert is a pragmatic randomised controlled trial (RCT), embedded in the EHR, which seeks to determine whether a computerised alert for the clinical team can change clinician behaviour during routine NHS care at University College London Hospitals NHS Foundation Trust (UCLH). Patients with suspected fluid overload will be identified based on the prescription of intravenous furosemide, a medication used to stimulate diuresis (increased urine output) to remove excess fluid. A repeat prescription of intravenous furosemide within the first 48 hours of an unplanned admission will trigger the alert. A clinician from the treating team will then be asked to consider enrolling the patient into the RCT if they judge that oral fluid restriction might be beneficial but they have uncertainty about this (clinical equipoise). Enrolled patients will be randomised to either oral fluid restriction of 1 litre per day or no fluid restriction. This will then be actioned through documenting as part of the clinical plan in the patients record and then communicated to the patient and the rest of the clinical team, including nursing staff. The study will record the number of patients recruited into the trial and the effect of the alert on enrolled patients' subsequent oral fluid intake. There are no additional tests or follow up for patients and the trial finishes on discharge from the study site. All trial outcomes will use data collected from routine care and the study is supported by the UCLH Biomedical Research Centre, funded by NIHR.
NCT04241718
The objective of this feasibility study is to characterize the performance of the Aquadex FlexFlow® System with the hematocrit (HCT) feature in conjunction with Daxor's blood volume analyzer (BVA-100). The study will monitor blood volume changes during ultrafiltration (UF) therapy as a potential means to guide the removal of fluid in subjects hospitalized with acute decompensated heart failure (ADHF).
NCT05254951
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.
NCT06582368
The pulsatile pattern of the portal vein is considered a marker of right ventricular dysfunction, but volemia may also contribute to this phenomenon. The separate influence of each factor remains debated, as the interplay between right ventricular dysfunction and volume status is complex. Additionally, right ventricular dysfunction can originate from either diastolic or systolic dysfunction, further complicating the understanding of their distinct impacts on portal vein pulsatility.
NCT05264454
The size of the inferior vena cava (IVC) using point of care ultrasound is used in resuscitation of patients who are critically ill and is now being used as a standard part of resuscitation in many clinical situations. Multiple factors can effect the size of the IVC including the type of oxygen devices the patient is currently on. In the ICU setting, the use of High Flow Nasal Cannula (HFNC) is often used to help in patients who are critically ill. There is some evidence to suggest that the use of HFNC can effect the size of the IVC measurement but the extent of the effect has not been well characterized. The purpose of this study is to determine the effect HFNC has on the size of the IVC measured using a point of care ultrasound.

Evaluation of fluid status in cardiac surgery patients using bioelectrical impedance and its impact on postoperative morbidity and mortality
NCT06326112
The RADAR-Canada trial is a pilot RCT undertaken to assess the acceptability of, compliance with, and biologic consequences of a deresuscitation protocol designed to expedite the removal of excess interstitial fluid in patients who remain in a positive fluid balance following admission to an intensive care unit (ICU).
NCT05927285
During cardiorenal syndrome type 1 (CRS1) vascular congestion is the major contributor to worsening renal function, but promoting decongestion with routine clinical evaluation is ineffective in some patients. The venous evaluation by ultrasound (VExUS) may optimize its management when evaluating for improvement in kidney function and other metrics related to decongestion.
NCT04576806
A randomized controlled clinical trial. 24 adult ICU patients will be recruited upon decision to administer fluid bolus of 500ml of crystalloid. The fluid will then be randomized to be infused at controlled room temperature or warmed to body temperature. Hemodynamic measurements will be made for 2 hours following the bolus, and laboratory values will be noted. The hypothesis is that part of the hemodynamic response will differed in response to cooling, and be larger in the cold group.
NCT03990311
This is a randomized clinical trial in which maintenance hemodialysis patients will be provided with salt restricted 'dialysis friendly' meals and compared to a control arm receiving usual care.
NCT05676723
The Starling system is a completely non-invasive hemodynamic monitoring technique. It is able to measure the thoracic fluid content (TFC). The TFC is supposed to reflect the total content of fluid in the thorax. Thus, TFC may include two of the variables that are commonly used for hemodynamic monitoring: the extravascular lung water (EVLW), and the global end-diastolic volume (GEDV). However, whether the TFC actually reflects GEDV and EVLW has not been clearly established. The objective of the study is to establish the determinants of TFC among hemodynamic variables including EVLW and GEDV.

Pathophysiology of perioperative fluid management in patients undergoing emergency laparotomy.
NCT04298931
It is well known, that patients with circulatory impairment sometimes, but not always, benefit from intravenous fluids. Predicting if a fluid administration will improve circulation is therefore of substantial clinical interest. Ventilator treatment induces cyclic variation in blood pressure due to interaction between the lungs and the heart. This variation is minor, but its amplitude may be used for guiding fluid administration. However, this method of using ventilator-induced variation in blood pressure to predict the effect of fluid administration was developed when different settings for ventilator treatment was recommended, compared with today. With today's recommend ventilator treatment, the method is, unfortunately, less reliable. The investigators will investigate how different ventilator settings influence variation in blood pressure, and the investigators will test if this knowledge allows us to better predict the effect of a fluid administration, by taking the ventilator settings into account.
