Early Deresuscitation Strategy Driven by Tissue Perfusion in Renal Replacement Therapy in Patients With Acute Renal Failure

"During the RRT, UFnet will be settled on 2ml/kg/h and adapted to hemodynamic tolerance and tissue perfusion .~When the patient's baseline body weight is reached the UF net will be settled to maintain it.~In case of failure of the fluid balance negativation after 24h, UFnet will be settled on 3ml/kg/h. Then when the baseline body weight is reached UFnet will be settled on 0.5 et 1ml/kg/h or if necessary adapted to 1,5ml/kg/h to maintain it~In case of hemodynamic intolerance (NADN \> 0,5 µg/kg/min) or tissue hypoperfusion, UF net will be stopped during 6 hours and restarted if NADN \< 0,5 µg/kg/min and without tissue hypoperfusion."

"During the RRT, UFnet will be settled between 0 et 1 ml/kg/h and adapted in case of weight stabilization failure or hemodynamic intolerance.~In case of weight stabilisation failure ( variation \>3% after 24h), the UF net can be increased to 1,5 ml/kg/h, as long as high intakes require UFnette at 1.5mL/kg/h to stabilize water balance, with daily reassessment.~In case of hemodynamic intolerance (NADN \> 0,5 µg/kg/min), UF net will be stopped during 6 hours and restarted if NADN \< 0,5 µg/kg/min."
