Filter by:The mortality of acute renal failure (ARF) remains to be high (around 60-70%) despite manifold improvements in ICU care. At present, it is not clear if the method chosen for renal replacement therapy, i.e. intermittent haemodialysis (IHD) or continuous haemofiltration (CVVH), might impact on the outcome of these patients. For this purpose, a prospective randomised clinical study of the effect of continuous versus intermittent renal replacement therapy on the mortality and outcome of acute renal failure will be performed.
The purpose of this protocol is to evaluate the safety of a selective cytopheretic device (SCD) in patients that are on continuous renal replacement therapy (CRRT) for acute renal failure (ARF).
Acute kidney injury is often treated with the use of continuous renal replacement therapy. Two commonly used treatments are continuous venvenous hemofiltration (CVVH)and continuous venovenous hemodialysis (CVVHD). CVVH uses convective clearance to remove toxins and solutes from the patients circulation, while CVVHD relies on diffusive clearance to remove these same toxins/solutes. This study will evaluate which of these two methods is more effective at clearing the body of waste/solutes. We hypothesize that renal replacement therapy by either modality (hemodialysis or hemofiltration; CVVHD or CVVH, respectively) using a modern membrane and higher blood flow rates will be associated with similar clearances of both small and middle molecular weight solutes. We further believe that continuous renal replacement therapy using CVVHD will be associated with decreased clotting events and longer hemofilter survival, as well as improved resource utilization (i.e. nursing time, alarms, etc.).
Intradialytic hypotension (IH) is a major complication during acute hemodialysis. The aim of this study was to evaluate the effects of dialysate temperature (DT) reduction with Na and ultrafiltration (UF) profiling on hemodynamics of critically ill acute kidney injury (AKI) patients submitted to sustained low-efficiency dialysis (SLED).
The low molecular weight heparin nadroparin is used for anticoagulation of the extracorporeal hemofiltration circuit. Continuous hemofiltration is a renal replacement modality for intensive care patients with acute renal failure. Up to now it is not known whether nadroparin is removed by hemofiltration or not. Accumulation would increase the risk of bleeding. Aim of the present study is to determine 1. whether nadroparin accumulates in plasma 2. whether nadroparin is removed by filtration and whether removal depends on hemofiltration dose 3. the effects of nadroparin during critical illness on coagulation and anticoagulation
The primary objective of the study is to demonstrate the efficacy of 60% ethanol lock solution in preventing major catheter related infections in critically ill patients.
Oxidative stress is associated with kidney damage in several different situations, including hypotension. In animal models it has been shown that the combination of n-acetylcysteine plus deferoxamine is superior to its isolate use in the treatment of several diseases. Thus the investigators aimed to determine if the administration of n-acetylcysteine plus deferoxamine could prevent renal failure in critical ill patients who develops hypotension.
Measuring novel proteins in the urine of surgical patients that can be used to diagnose impending acute or chronic renal failure.
Aim1a: Statin naive patient's scheduled for cardiac surgery will be randomized to 80mg atorvastatin or placebo on the day prior to surgery and then 40mg daily thereafter until hospital discharge to test the hypothesis that short-term atorvastatin use decreases: 1. acute kidney injury following cardiac surgery. 2. postoperative delirium following cardiac surgery. Aim1b: Patients using statins preoperatively will be randomized to atorvastatin 80mg or placebo on day of surgery and 40mg or placebo on postop day 1 with resumption of preoperative statin therapy on postop day 2 to test the hypothesis that short-term atorvastatin use decreases: 1. acute kidney injury following cardiac surgery. 2. postoperative delirium following cardiac surgery. Endpoints include glomerular filtration, urine and plasma markers of renal dysfunction, markers of oxidative stress, mitochondrial function, systemic inflammatory markers, delirium, dialysis, stroke, myocardial infarction, time to extubation, ICU length of stay, and death.
1. Sustained low efficiency daily hemodiafiltration(SLEDD-f) is a kind of renal replacement therapy with high-flux dialyser membrane (helixone). 2. The pore size of helixone is larger than most antibiotics, and vancomycin is supposed to be removed during dialysis. 3. Our study wants to find the amount of vancomycin removed during SLEDD-f, and try to find the most appropriate dose regimen for this kind of patients.
