Filter by:The study is a case-control study with the primary aim of objectifying the volume status of patients receiving hemodialysis. Volume status will be assessed at dry weight and evaluated by a carbon monoxide rebreathing method, that measures blood volume, and bioimpedance that measures total body water. Case-control subjects will be matched on gender, age and weight. Secondary aims are to evaluate the carbon monoxide rebreathing method. Blood volumes obtained by the carbon monoxide rebreathing method will be correlated to blood volumes obtained by radioactive labelling of erythrocytes and albumin. In addition, it will be investigated whether hemoglobin is a valid marker of anemia in patients receiving hemodialysis by measuring the erythrocyte volume and the hemoglobin mass by the carbon monoxide rebreathing method and correlating this to the hemoglobin concentration measured before and after dialysis.
Pilot-scale, single-arm,observational study to assess the utility and acceptability of a wearable hydration monitor in haemodialysis patients compared with bioimpedance and haemodialysis machine data.
Fluid overload (FO) puts aortic stenosis (AS) patients at risk for heart failure and death. However, conventional FO assessment, including rapid weight gain, peripheral edema, or chest radiography, is inaccurate. Bioelectrical impedance spectroscopy (BIS) allows objective and reproducible FO quantification, particularly if clinically unapparent. FO as detected with BIS has recently been linked to worse clinical outcomes of AS patients undergoing transcatheter aortic valve replacement (TAVR). It is the aim of the present randomised trial to evaluate the potential clinical benefit of pursuing an individualized decongestion treatment strategy in consecutive TAVR patients using BIS.
Optimization of perioperative fluid management is important for preventing adverse events, such as hypovolemia, cardiogenic shock, volume overload, and pulmonary edema, in both adult and pediatric patients. If the intravascular (IV) fluid volume is not optimized, pediatric patients are at risk of dehydration or volume overload. Perioperative IV fluid therapy is important during and after induction of general anesthesia (GA).The aim of this study is to investigate the difference between conventional and restrictive fluid replacement regimens using lung ultrasound in pediatric patients undergoing penile hypospadias repair, as a surgery with minor fluid loss.
The investigators are proposing a prospective, randomized, double blinded, placebo-controlled single center study evaluating the role of co-administration of oral sodium chloride (NaCl) with intravenous diuretics in patients hospitalized with acute decompensated heart failure. The investigators are approaching this study with the hypothesis that the use of oral sodium chloride leads to improved effective diuresis (as measured by weight loss) and renal function as compared to placebo in patients hospitalized with acute decompensated heart failure undergoing aggressive intravenous diuretic therapy.
A common complication of the progression of cirrhosis is fluid retention (ascites, edema, or pleural effusion). Loop diuretics are the treatment of choice for fluid retention in cirrhotic patients; however, many of these patients demonstrate diuretic resistance, requiring higher doses of the diuretics to achieve adequate diuresis. The cause of this diuretic resistance is hypothesized to be secondary to hypoalbuminemia which has led some providers to give human albumin in combination with loop diuretics to increase intravascular volume and facilitate diuresis. However, this practice remains controversial because minimal data exists to support its efficacy. The purpose of this study is to compare the efficacy of diuretics alone versus diuretics in combination with albumin in cirrhotic patients presenting with fluid retention.
Background: Intravenous fluid replacement during transurethral resection of the prostate is still unclear. Ultrasonography of the inferior vena cava (IVC) has been recently used to assess the volume status and predict fluid responsiveness. In this double-blind, randomized controlled study, we will assess the IVC at baseline and at subsequent time points after spinal anesthesia, and according to IVC diameter will give the replacement challenge colloid. Potential problems during TURP are mostly due to either fluid overload or bleeding: Intraoperative TURP syndrome, Hemorrhage, Myocardial ischemia, Hypothermia, Prostatic capsular perforation, Bladder or urethral perforation. Postoperative TURP syndrome, myocardial ischemia/infarction, Postoperative cognitive impairment. Study Hypothesis: Strict colloid volume optimization using US-guided IVC diameter calculation aiming decrease the total IV fluid volume and accommodate the transurethral inevitable absorption of currently used irrigation crystalloid fluid (Nacl0.9%) that accidentally absorbed and change it from a circulatory overload to a complementary part of the replacement IV fluids preventing fluid overload and TURP syndrome. Aim of the work: To reduce Intraoperative and postoperative fluid overload during TURP surgery with hemodynamic stability relaying up on US-guided IVC diameter dependent Strict IV Colloid replacement volume optimization. Methods: A prospective randomized controlled trial on ASAI-III male patient aged 40-80 years old subjected to transurethral endoscopic resection of the prostate (TURP) surgery. Then patients will be divided into 2 groups according to the IV infusion fluid type as follow: Crystalloid -control group: (preload plus continuous IO Ringer acetate crystalloid 4/2/1 rule infusion) according to the usual 4/2/1 rule. Not guided by IVC diameter but IVC diameter will be calculated using the US and recorded at baseline just after spinal anesthesia and then every 30 minutes till the end of surgery. Loop Diuretic (Furosemide) will be given according to the maximum diameter of the IVC as follow; 10mg if IVC>2.5Cm. Colloid- study group: (preload plus colloid challenge only); Fluid challenge boluses of 250 mL (over 5 minutes using a pressurizer) 6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride (voluven®) if the IVC<1.7(higher limit of normal) will be given guided by IVC diameter at baseline just after spinal anesthesia and then every 30 minutes till the end of surgery.
First in Human feasibility and sfafety study of the alfapump DSR system in the treatment of Heart failure subects resistant to diuretic therapy. Up to 10 subjects will be enrolled in up to 3 centres in Belgium and Georgia and will be iplanted with the alfapump DSR system. Subjects will undergo DSR titration during a 2 week hospitalisation period, and will continue titrated DSR therapy as outpatients for 4 more weeks.
Researchers are observing the values of proEnkephalin (PENK) via a blood draw in hospitalized patients that are volume overloaded requiring diuresis. If changes in PENK are found, physicians may predict values of change in kidney function during treatment.
The following pilot study will be undertaken to determine the effects of use of a zero-sodium peritoneal dialysate solution (10% dextrose in sterile water) on sodium removal as compared to a standard peritoneal dialysis solution.
