[Predilution and postdilution hemodiafiltration].
Over the years hemo(dia)filtration therapies have received considerable impetus owing to the simplified techniques and optimal hydraulic management. Today, these technological improvements allow large amounts of on-line fluid exchange with the resulting clinical benefits. After a brief historical review, this article describes the main characteristics of predilution and postdilution hemodiafiltration based on the current literature, emphasizing the technical peculiarities as well as the clinical advantages in terms of patient survival. Particular attention is paid to the physical and hydraulic principles, and to new programs that optimize dialysis efficiency.
