The state of hyperhydration in critically ill patients with acute kidney injury (AKI) is associated with increased mortality. Bioelectrical impedance vector analysis (BIVA) appears to be a viable method to access the fluid status of critical patients but has never been evaluated in critical patients with AKI. The objective of this study is to evaluate the hydration status using BIVA in critical patients under intensive care at the time of AKI diagnosis and to correlate this measurement with mortality. A sample of 224 patients with AKI will be evaluated by BIVA and followed until they are discharged or death in intensive care unit and the BIVA vectors will be analysed to define differences in hydration characteristics from each group.
Patients admitted to Intensive Care Unit (ICU) will be assessed by BIVA at the moment of the AKI diagnosis. They will be followed up to 12 weeks, until hospital discharge or death. The association between survival and hydration status, as assessed by BIVA in the first AKI day, will be tested.

The study evaluates how outcome varies among critically ill patients with and without acute kidney injury. Data from the Swedish Intensive care register and other Swedish national register...
Acute kidney injury is associated with a rise in serum uric acid during cardiovascular surgery and can cause poor blood flow to the kidneys making them vulnerable to kidney injury. We hypo...
This proposal will incorporate statistical models developed by the investigators to predict risk for acute kidney injury into our electronic medical record system, enabling an alert to not...
Acute kidney injury (AKI) affects approximately 20% of hospitalized patients and up to 67% of those admitted to an intensive care unit (ICU), making it among the most common organ dysfunct...
In this trial, patients with acute kidney injury who have recently received a drug that may affect kidney function will be randomized to having an alert placed in the electronic health rec...
Acute kidney injury is common and is associated with increased morbidity and mortality. Rates of acute kidney injury in most settings remain high and in some settings are increasing. Moreover, outcome...
Background The epidemiologic characteristics of children and young adults with acute kidney injury have been described in single-center and retrospective studies. We conducted a multinational, prospec...
Acute kidney injury occurs early in PICU admission and increases risks for poor outcomes. We evaluated the feasibility of a multicenter acute kidney injury biomarker urine collection protocol and meas...
There is recent evidence to show that patients suffering from acute kidney injury are at increased risk of developing chronic kidney disease despite the fact that surviving tubular epithelial cells ha...
Acute kidney injury (AKI) is associated with high morbidity and mortality, and may lead to chronic kidney disease (CKD). Traditional serum biomarkers for acute and chronic renal dysfunction are insens...
Abrupt reduction in kidney function defined as an absolute increase in serum CREATININE of more than or equal to 0.3. mg/dl, a percentage increase in serum creatinine of more than or equal to 50%, or a reduction in urine output. Acute kidney injury encompasses the entire spectrum of the syndrome including acute kidney failure; ACUTE KIDNEY TUBULAR NECROSIS; and other less severe conditions.
Acute kidney failure resulting from destruction of EPITHELIAL CELLS of the KIDNEY TUBULES. It is commonly attributed to exposure to toxic agents or renal ISCHEMIA following severe TRAUMA.
A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
Conditions in which the function of KIDNEYS deteriorates suddenly in a matter of days or even hours. It is characterized by the sudden drop in GLOMERULAR FILTRATION RATE; (GMR). The most severe stage is when the GFR drops below 15 ml per min (ACUTE KIDNEY FAILURE).
