title: A new hemodialysis monitoring device using filtrate concentrations: a comparison with standard serum techniques.
abstract: A new device allowing sampling to be performed at any time, and using the filtrate obtained during hemodialysis is described. The device was used in 27 patients undergoing regular dialysis. Urea, creatinine and potassium were measured in samples taken both from arterial blood and from the device at 10, 40, 120 and 230 minutes after the beginning of the dialysis. The results were compared. A constant bias of about 10% was noted between the two sets of results but statistical analysis showed this was correctable.
