The efficiency of haemodialysis has been determined when a Watson-Marlow (Kiil) dialyser was used repetitively without changing the membranes. Dialysis efficiency was assessed from the clearance of creatinine and of urea from the patient's blood. No significant deterioration in dialysis could be detected in six dialyses through the same membrane. Leaving the dialyser unit for up to eight hours before washing it out after the completion of each dialysis did not appear to have any effect on dialysis efficiency.
It was concluded that repetitive haemodialysis through the same membranes is possible, but careful monitoring of the patient to assess suitability for such treatment, and subsequently at each dialysis, is essential.
