Conditions

Acute Kidney Injury Requiring Continuous Renal Replacement Therapy

Brief summary

This clinical trial aims to investigate whether the low treatment intensity (12 mL/kg/hr, low-dose hemodialysis/filtration) or the medium treatment intensity (25 mL/kg/hr, standard-dose hemodialysis/filtration) is more effective and safer for continuous renal replacement therapy in critically ill patients.

Interventions

DRUGDialysate fluid, Filtration replacement fluid

Dose of continuous hemodialysis and/or hemofiltration
