Significant clearance for myoglobin has been reported for high flux membranes from < 8 mL/min (5) up to 22 mL/h (CVVH) (10) and for high cut-off (HCO) membranes a mean clearance rate of 36.2 mL/min in HD mode (7) and 39.2 mL/h in CVVH mode (5). The use of high cut-off (HCO) continuous veno- venous hemodialysis (CVVHD) may constitute a novel therapeutic strategy for effectively reduction of myoglobin in the patient's serum to ameliorate the course of AKI.
