Implementing On-Line Hemodiafiltration as a Renal Replacement Therapy for ICU Acute Renal Failure: A Single-Center Report of Feasibility, Safety and Hemodynamic Tolerance over a Seven-Year Period

Background/Aims: On-line hemodiafiltration (HDF) is not yet routinely used in ICUs given the potential risk of microbial contamination of dialysis fluids. We evaluated the safety and the tolerance of its use in our ICU. Methods: A weekly measurement of bacterial growth (CFU/ml) and endotoxin level (endotoxin units/ml) was performed in dialysis fluids over a 7-year period. Intradialytic hypotensive events and pyrogenic reactions were collected during 466 on-line HDF sessions. Results: A bacterial count
