The article discusses how the area and permeability characteristics of the peritoneal membrane compare with conventional cellulosic hemodialysis membranes. As most patients on chronic peritoneal dialysis require hypertonic exchanges to remove excess total body water, it is probably reasonable to expect peritoneal insulin dialysate to be higher than the mean value of 6 ml/min determined for isotonic exchanges. The portion of the peritoneal membrane that participates in solute exchange from blood to dialysate is considerably less than 1 sq m in area but has greater permeability for intermediate molecular weight solutes than does cellulosic membrane.
