Is the choice of membrane important for patients with acute renal failure requiring hemodialysis?
It has recently been reported that patients with acute renal failure requiring hemodialysis have an improved recovery of renal function and a higher survival rate when the dialysis treatments are performed with a biocompatible membrane rather than a bioincompatible membrane. Our data, obtained in 57 patients with acute renal failure, do not support these findings since neither the mortality nor the required number of dialysis sessions could be influenced by using a biocompatible membrane. The survival rate was similar in both groups (64 versus 72%), and renal function was regained in both groups after 6 dialysis sessions. We conclude that when reviewing the literature as well as other factors, the underlying clinical condition or the skill of the physicians is probably more important than the theoretical superiority of biocompatible membranes.
