Brief Summary

Does Early Initiation of Renal Replacement Therapy Have an Impact on 7-day Fluid Balance in Critically Ill Patients with Acute Kidney Injury with Positive Furosemide Stress Test?: a Multicenter Randomized Controlled Trial

Detailed Description

The objective is to determine if early initiation of renal replacement therapy guided by positive furosemide stress test has an impact on 7-day fluid balance in critically ill patients with acute kidney injury

Target Recruitment
118
Inclusion Criteria
  • Age older than 18 years old and admission in an ICU
  • Acute kidney injury (defined by serum creatinine increase ≥ 0.3 mg/dL or urine output ≤ 0.5 mL/kg/hour according to KDIGO criteria)
  • Informed consent provided by the patient or person with decisional responsibility
  • Indwelling bladder catheter
  • Documented cause of acute kidney injury from acute tubular necrosis e.g. presence of granular or epithelial casts on urine sediment, FeNa more than 1%, Feurea more than 50%, urine or plasma neutrophil gelatinase-associated lipocalin (NGAL) more than 150 mg/dL
  • Opinion of the treating clinical team that patient was well resuscitated and sufficiently clinically stable for the intervention or by noninvasive or invasive measurements i.e. fluid accumulation at least 5% plus at least one of the following e.g. chest radiography, central venous pressure ≥ 8 mmHg, pulse pressure variation < 13%, inferior vena cava collapsibility index < 50% in spontaneously breathing patients or distensibility index < 18% in mechanically ventilated patients
Exclusion Criteria
  • Baseline serum creatinine ≥ 2 mg/dL (male) and ≥ 1.5 mg/dL (female) within 3 months
  • Evidence of volume depletion at the time of furosemide administration or active bleeding
  • Evidence of obstructive uropathy, renal vein thrombosis or renal artery stenosis, thrombotic microangiopathy, glomerulonephritis, tumor lysis syndrome
  • History of renal allograft
  • Known pregnancy
  • Allergy or known sensitivity to loop diuretics
  • Need for emergency renal replacement therapy at randomization or evaluation by the clinical team that the renal replacement therapy should be deferred
  • Patient is moribund with expected death within 24 hr or whom survival to 28 days is unlikely due to an uncontrollable comorbidity (cardiac, pulmonary or hepatic end-stage disease; hepatorenal syndrome; poorly controlled cancer; severe post-anoxic encephalopathy; etc.)
  • Patients with advance directives issued expressing the desire not to be resuscitated
  • Prior treatment with RRT within 30 days
