Continuous monitoring of the efficiency of haemodialysis by recording the UV transmittance of the dialysis solution.

The efficiency of haemodialysis, the elimination of uraemic retention substances of low and medium molecular weight can be continuously monitored by recording the UV transmittance at 254 nm of the dialysing solution. The method for controlling the efficiency of haemodialysis is optimal if it complies with the following requirements: No or little blood sample is needed. The elimination process can be continuously monitored. The degree of eliminating the hardly dialysable organic compounds and toxic materials can be well measured. Our method was devised to fulfil the above requirements [1]. The results obtained during routine application of the method are reported in this publication.
