[High-efficiency hemodialysis. Review of the literature and initial clinical experience]

A literature review allows us to distinguish two types of high efficiency therapy: HED (high efficiency dialysis), with low ultrafiltration coefficient membranes, and HFD (high flux dialysis), with high ultrafiltration coefficient membranes. Data reported show an unchanged hematochemical with the same, or better, treatment tolerance, but there are few data on hydrosaline balance (and correlate hypertension) and middle moleculas removal. Finally we report the experience of our centre in 59 months of treatment in four patients.
