Summary A large‐area short‐time (LAST) haemodialysis regimen (three hours by three times per week on a 2·5 M 2 haemodialyser) has been compared with conventional haemodialysis (six hours by three times per week on a 1·3 M 2 haemodialyser) on four patients over a period of eight months. Parameters monitored throughout the study included: Serum biochemistries, haematocrit, extracellular fluid space, platelet function, granulocyte kinetics, immunological status and neurological status. All patients showed weight increases (3–12%) during the LAST dialysis period. These increases were related to problems of intradialytic hypotension which resulted from the increased rate of fluid removal required during the LAST dialysis period. Hypotension was not a problem during routine treatment over six hours. During LAST dialysis all patients showed an increase of 10–20% (P < 0.05) in predialysis serum urea and creatinine and a moderate decrease in predialysis serum bicarbonate (from 24·8 ± 2·2 to 21·4 ± 2·6 mM/I, P < 0.005). This study indicates that, providing fluid balance can be controlled, a LAST dialysis regimen provides comparable therapy to conventional haemodialysis. However, recent studies have suggested that short‐time dialysis may be possible with conventional 1.0 to 1.3 M 2 haemodialysers, indicating that short‐time haemodialysis may not need to involve more costly large‐area haemodialysers.
