Sodium Bicarbonate and N-Acetylcysteine for Nephroprotection in Acute Myocardial Infarction
Acute Myocardial InfarctionAcute Kidney InjuryContrast-induced nephropathy (CIN) represents a potential complication of diagnostic and therapeutic procedures in interventional cardiology, especially in the acute setting of primary PCI. The investigators will test the efficacy of sodium bicarbonate (NaHCO3) and N-acetylcysteine (NAC) on the prevention of acute events and CIN in patients with acute myocardial infarction.
Examining New Diagnostic Tests for Acute Kidney Injury After Heart Surgery
Kidney FailureAcute1 morePeople who undergo coronary artery bypass grafting (CABG) or heart valve surgery may experience acute kidney injury (AKI) after their surgery. Current medical tests cannot identify AKI until approximately 48 hours after it occurs. This study will examine three new biomarkers in blood and urine that may provide a more effective and faster way of predicting AKI in people who undergo CABG or heart valve surgery.
Near Infrared Spectroscopy for the Detection of Acute Kidney Injury in Children Following Cardiac...
Acute Kidney InjuryHeart; Dysfunction Postoperative2 moreOne in a hundred children is born with a heart defect. Some children require heart surgery within the first few days of life, while others can wait until they are older. A complication of open-heart surgery is low blood flow due to the heart-lung machine that can cause sudden loss of kidney function known as acute kidney injury (AKI). AKI causes complications that can increase hospital length of stay and increase risk of death. Current ways to identify AKI are not able to it until 2 or 3 days after it has occurred. Because of this, there is not a specific treatment for AKI. If the investigators diagnose AKI early, they might be able to treat it and improve outcomes in children. NIRS is a skin monitor that can detect low blood flow to the kidney and might help diagnose AKI when it occurs in the operating room. The use of NIRS to diagnose AKI early is the focus of this study.
Study of Patients With Acute Renal Failure on CVVH
Renal FailureAcute kidney failure is common in children in the Pediatric Intensive Care Unit (PICU). You are being asked to participate in this study because your child is being treated for kidney failure with continuous veno-venous hemofiltration (CVVH). CVVH is a continuous, gentle form of removing excess fluids and small wastes from the blood, similar to kidney dialysis (artificial kidney). It is an accepted therapy for temporary support of kidney failure. In some patients with acute kidney failure, beginning CVVH is followed by a temporary decrease of urine output. The reason why this happens is currently unknown. The purpose of this study is to determine why this happens.
Measuring Bladder Volumes Scanning in the ICU
Urinary RetentionAcute Kidney InjuryICU patients are at risk for catheter associated urinary tract infection. Frequently patients can't tell clinicians if they need to void if the catheter is removed. If clinicians know that an accurate volume measurement s of urine volume in the bladder can be obtained when the catheter is removed, catheters could be removed earlier and more frequently and thus possibly avoid an infection. For this study, measures with ultrasound (directly visualizing the bladder to measure), bladder scanner (partially blind measure with placement of scanner over the expected bladder location on the skin) and urine catheterized volume will be obtained. The investigators also want to know if the technology is user dependent. The study will include 2 levels of nurses RN and advanced practice RN (APRN) perform the bladder scanner. An APRN and MD will conduct the ultrasound. Ultrasound is technology primarily used by physicians but APRNs are using the technology technology more frequently. After these 4 measurements, the patient's nurse will perform an intermittent straight catheterization (catheter inserted, urine drained, and catheter removed) as the gold standard comparison.
AKI Management Using Electronic Alerts
Acute Kidney InjuryAcute kidney injury (AKI) is a common clinical event with severe consequences. In the United States alone, greater than one million hospitalized patients per year are diagnosed with AKI. It has been independently associated with prolonged hospital stays, 25-80% risk of in-hospital death, and future progression to chronic kidney disease. While there has been an increase in awareness about the prevalence and significance of AKI, studies have uncovered systematic failure in the management of AKI, largely relating to the failure of clinicians to recognize and manage the condition appropriately. This is where we can use electronic health records (EHRs) and electronic alerts (e-alerts) to our advantage. In this study, the investigators plan to use e-alerts integrated into a clinical decision support (CDS) system to improve the care of and outcomes of patients with AKI. The aims are to study the prevalence of AKI and its progression among hospitalized patients using an 'AKI sniffer' (an EHR based automated system) and to prospectively study if introducing a complex intervention (an e-alert combined with a clinical decision support system) will reduce progression of AKI in children. The investigators have developed an AKI care bundle which provides simple guidelines for management of AKI along with specific discharge instructions to improve follow up care. The primary outcome is AKI progression. Secondary outcomes include morbidity, mortality, length of hospital stay, need for renal replacement therapy, and recovery of renal function by time of hospital discharge. The investigators will also look at documentation of AKI and if these participants get appropriate follow up.
Biomarker Effectiveness Analysis in Contrast Nephropathy (BEACON)
Acute Renal FailureKidney Diseases2 moreThis study is an observational non-interventional study which will examine a) the accuracy of biomarkers in predicting renal and cardiovascular outcomes after contrast-induced acute kidney injury. This study will obtain de-identified human plasma & urine samples and corresponding de-identified research study data on subjects who are enrolled into the Prevention of Serious Adverse Events Following Angiography (PRESERVE) study and Biomarker Collection and Analysis in the PRESERVE Trial (VA CSP #578). Biomarker analyses will be performed on the de-identified samples and merged with de-identified research study data.
Prognostic Biomarkers For Acute Kidney Injury In Liver Cirrhosis
Acute Kidney InjuryLiver Cirrhoses1 moreAcute kidney injury (AKI) is a common and under-diagnosed problem in patients with liver cirrhosis, and is associated with significant illness and preventable death. Blood (serum) creatinine is the current test for kidney function, but it is an insensitive and non-specific marker in cirrhosis. The investigators hypothesise that blood (plasma) levels of kidney injury molecule-1 (KIM-1) will detect AKI earlier and predict the risk of worsening AKI in cirrhosis, thus identifying patients in need of prompt and effective treatment and improving patient outcomes. The investigators will collect blood and urine samples from cirrhosis patients admitted into hospital and study the relationship between plasma KIM-1, other diagnostic 'biomarker' tests that have recently been proposed, and patient outcomes.
