Abstract

  High Flow means the increase of dialysate flow rate in continuous renal replacement therapy (CRRT) and at least 1L/h is required. These words are used together continuous hemodialysis (CHD) or continuous hemodiafiltration (CHDF) . High Volume means the increase in the filtration flow rate in CRRT and requires a filtration flow rate of at least 1L/h. These words are used together continuous hemofiltration (CHF) or CHDF. When both the dialysate flow rate and filtration flow rate are increased to more than 1L/h, this is called High Flow-High Volume (HF-HV) CHDF. HF-HV CHDF improved the recovery rate from hepatic coma in our institute. Ronco et al. provided data that showed that high volume CHF (more than 35ml/kg/hr filtrate) was associated with a better survivor rate than lower volume CHF (20ml/kg/hr filtrate) . For septic shock patients, high volume CHF or HFHV-CHDF might offer/provide a better prognosis than conventional dose CRRT.
