A clinical study of the efficacy of combined hemodialysis and hemoperfusion in the prevention of uremic encephalopathy

Objective To evaluate the efficacy of combined hemodialysis-hemoperfusion therapy compared with conventional dialysis in preventing uremic encephalopathy. Methods 45 enrolled patients on maintenance hemodialysis were randomized to receive conventional hemadialysis(control group,21 cases)or combined with monthly sequential hemoperfusion (study group,24 cases). The duration of hemoperfusion was 2-3 hours and 4.5 hours for use of hemodialysis. Blood flow rates were maintained at 200-250 ml/min and dialysate flow rate was at 500 ml/min. Anticoagulation was performed with heparin sodium or low-molecular-weight heparin calcium. Observation was made on incidence of uremic encephalopathy. Results 7 cases developed uremic encephalopathy in control group compared to only 1 case in study group, in which significant improvement of quality of life was also observed. Conclusion Use of hemodialysis-hemoperfusion therapy could effectively prevent the development of uremic encephalopathy in maintenance dialysis patients.
