... HD treatment. Summary: A prospective, multicenter, parallel group comparative trial examined the clinical effectiveness of I-HDF compared with predilution on-line HDF (pre-HDF), the most popular on-line HDF therapy in Japan. Patients were allocated to 2 groups after matching for age (± 5 years...

... to be greatly affected by the dilution modes (methods of infusing substitution fluid) in HDF. In predilution HDF, the substitution fluid is infused upstream of the dialyzer, and the shear stress on blood cells is expected to increase with increasing linear flow velocity. In postdilution HDF, the substitution...

Among dialysis modalities assessed in this study, postdilution HDF offers the most efficient modality both in terms of solute removal capacity and substitution volume used. The predilution HDF mode provides slightly...

... Abstract Mid-dilution (MidD) is a new concept allowing post- and predilution in the same dialyser(Olpur® MD 190). The aim of the study was to compare, in 6 patients, MidD with postandpredilution wird regard to purifi cation tests, such as reduction ratios and instantaneouswhole-blood clearances...
