Biocompatible membranes in intermittent hemodialysis (IHD) and acute renal failure (ARF): effect on outcomes. The choice of dialysis membrane and its influence on survival from ARF has been of major interest to investigators over the last few years. While the evidence tends to support a survival advantage for biocompatible membranes, most of the studies were not well controlled. The most recent multicenter study showed an improvement in mortality and recovery of renal function with biocompatible membranes; however, this effect was not significant in oliguric patients. Further investigations are required in this area. NS—not significant.
