Using a conventional hemodialysis machine, the dialysate flow rate is reduced to between 100 mL/min and 300 mL/min (depending on the machine) and the duration of treatment is extended, usually to between 8 and 16 hours. PIRRT using slow hemodiafiltration has been well described as sustained low-efficiency daily diafiltration (SLEDD-f), although there are no data to suggest that convective clearance in this setting provides improved outcomes as compared to diffusive therapies (just as there are no data to support improved outcomes with CVVH or CVVHDF as compared to CVVHD). The technique was well described by Mark Marshall and colleagues from New Zealand more than a decade ago ((Marshall MR, et al. Sustained low-efficiency daily diafiltration (SLEDD-f) for critically ill patients requiring renal replacement therapy: towards an adequate therapy.Nephrol Dial Transplant. 2004 Apr;19(4):877-84); I have attached a link to the PDF of the manuscript to this post.The reply is currently minimized Show -
