accuracy of kt v estimations in high flux haemodiafiltration using per Cent Reduction of urea incorporation of urea rebound
Nephrology Dialysis Transplantation, 1993Co-Authors: Peter G Kerr, Angel Argiles, Bernard Canaud, J L Flavier, C MionAbstract:: The estimation of Kt/V by utilization of the pre- and postdialysis urea conCentrations (per Cent Reduction in urea and In(Upre/Upost)) provides a simple, quick technique that can be applied at the bedside. However, the accuracy of such techniques has been questioned. One possible reason for this inaccuracy may be the frequently observed postdialysis rebound in serum urea. We assessed the urea rebound at 30 min postdialysis in 34 haemodiafiltered patients and compared the calculation of Kt/V using this urea conCentration with that using the immediate postdialysis conCentration. These results were then compared to the Kt/V calculated by urea kinetic modelling (UKM), also utilizing the delayed serum urea conCentration. The degree of urea rebound observed was large, 21.4%, being a reflection of the short-duration, rapid-flux dialysis. The formulae for calculation of Kt/V all significantly correlated with Kt/V by UKM but all gave results significantly different from Kt/V by UKM (P < 0.001 by paired t test). For assessment of Kt/V by these formulae or by UKM, the urea rebound is too large to ignore in the setting of short-duration, rapid-flux dialysis.

Accidents at roundabouts in New South Wales
1990Co-Authors: R T TudgeAbstract:The number of roundabouts in NSW has grown from less than about a dozen in 1981 to over 500 in 1989. Until reCently there have been too few roundabouts in New South Wales to undertake a definitive study of their safety. This study is the first to attempt an analysis of safety at roundabouts in New South Wales. The location of roundabouts is interesting. About 70 per Cent are constructed on local roads and about 75 per Cent of roundabouts are in urban areas. In addition, they tend to be program phenomenon, with about 40 of the 176 councils in New South Wales having nearly 80 per Cent of the roundabouts. This pattern should change as roundabouts become more widely accepted as a traffic control device in New South Wales. The study shows that there has been a 50 per Cent overall Reduction in accidents at roundabouts with a 63 per Cent Reduction in fatal accidents, a 45 per Cent Reduction in injury accidents and a 40 per Cent Reduction in damage only accidents (A).
