Introduction: Methods: The patient was admitted to the ICU and daily review of laboratory tests was performed. After 36 hours of the initiation of the CCVHF levels of CK decrease significantly from 221.731 U/L to 108.000 U/L, with normalization of potassium levels as well with 4.7 mEq/L. Completing the 72 hours of CCVHF the levels of CK were 5.578 U/L, however hyperkalemia and hyperazoemia persisted Creatinine: 4.36 mg/dl, bun 68 mg/dl, potassium 5.8 mEq/L so conventional hemodialysis was prescribed. It is worth clarify that in our center we do not have myoglobin testing so the effectiveness of the therapy was measured by the decrease in CK serum levels. Nevertheless creatinine levels before medical discharge were 4.43 mg/dl therefore it was indicated to continue renal replacement therapy on an outpatient basis; nonetheless one week after hospital discharge, in the ambulatory renal unit recovery of renal function happens and a significant decrease in CK was documented Creatinine: 1.52 mg/dl CK: 398 U/L , so it was decided to withdraw hemodialysis therapy. I have no potential conflict of interest to disclose.
