About this trial

This is an interventional treatment trial for Acute Kidney Injury

Eligibility Criteria

18 Years - 89 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age 18-89
  • Acute renal failure or end-stage renal disease necessitating CRRT
  • Admitted to the MICU service
  • If on vasopressor/inotropic agent, norepinephrine as only intravenous pressor
  • If on vasopressor/inotropic agent, at stable pressor dose for at least four hours
  • If on IV fluids, stable dose of crystalloids <= 100cc/hour and is not receiving colloids for 4 hours or more prior to initiation of CRRT
  • Mean arterial pressure (MAP) >= 65
  • Arterial catheter present for continuous blood pressure monitoring
  • CRRT duration of 48 hours or less using NxStage System One dialysis system
  • successfully tolerated CRRT for at least 4 hours without clotting or hemodynamic instability
  • no other procedures, blood products transfusion, or additional medication administration are anticipated during the study period

Exclusion Criteria:

  • listed for organ transplant
  • atrial fibrillation, other irregular heart rhythm, unstable arrhythmia
  • need for more than one intravenous vasopressor agent
  • intravenous vasopressor/inotropic agent other than norepinephrine (ie dobutamine, dopamine, vasopressin, epinephrine)
  • therapeutic anticoagulation being administered
  • known acute myocardial infarction as defined by elevated troponin along with a documented clinical diagnosis during current hospitalization
  • known acute stroke, intracerebral hemorrhage, intracranial mass effect, or elevated intracranial pressure within the last 30 days.
  • dialysis catheter malfunction and unable to maintain target blood flow rate
  • fluid removal (ultrafiltration) rate > 100mL/hour
