Abstract

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 <0.1 CFU/ml was achieved in 977/978, 288/290, and 278/280, and an endotoxin level <0.03 endotoxin units/ml in 564/576, 330/337 and 318/323 ultrapure water, dialysate, and infusate samples, respectively. Seventy-six intradialytic hypotensive events but no pyrogenic reaction occurred.

Conclusion: The great majority of dialysis fluid samples were considered suitable with a 99% compliance rate. Use of on-line HDF, at a large scale of dialysate and infusate flows, is well tolerated and may be safely performed in critically ill.
