Clinical evaluation of patients dialysed with double Gambro 4 hours, three times per week.

To reduce the hours and cost of each dialysis and/or to increase adequacy of haemodialysis treatment 14 chronic dialysis patients were dialysed with two Gambro dialysers, 4 hr for 3 days per week. General well-being, anaemia, and nerve conduction velocity improved in some patients during the study period. Increasing dialysis surface area by using two Gambro dialysers enabled reduction of hours of dialysis, which was favourably accepted by all patients and decreased cost of dialysis, mainly by increasing the capacity of a unit to dialyse more patients with the same personnel and equipment.
