Abstract

In rapid accelerated hemodialysis (R-AHD), blood partially recirculates from the venous (outflow) to the arterial (inflow) line through a recirculation line (R) to selectively increase the filter blood flow rate (BFR). R-AHDPR uses two blood pump segments at the patient segment of the arterial line and at (R). To determine the effectiveness of R-AHD with regard to increasing anticoagulation and dialysis efficiency, ten children with end-stage renal disease in two stages were studied: stage 1 with 10 routine heparin R-AHD, then 10 half-dose heparin R-AHD, then 145 routine heparin R-AHD sessions for 1 month and then routine heparin double needle hemodialysis (DNHD) for one month (control). In stage 2, the patients with 10 routine heparin-mixed AHDPR and DNHD sessions were dialyzed, then eight low-dose heparin R-AHDPR” sessions, then one of the children with 10 no-heparin R-AHDPR sessions and then 10 routine heparin DNHD sessions” (control). Signs of blood clotting and dialysis efficiency were monitored. Blood clots appeared in four out of 165 R-AHD0 (one pump circuit) sessions but in none of the 28 R-AHDPR sessions. In stage 1, the mean urea reduction rate was 0.60, 0.60 and 0.70 for the R-AHD protocols, compared with 0.71 for the control (P>0.05). In stage 2, the arterial blood urea nitrogen was reduced by 0.66±0.15 after an R-AHDPR period, compared with 0.79±0.18 after a DNHD period (P=0.059). In conclusion, R-AHDPR allowed successful low heparin and no heparin hemodialysis in children without increasing the patients’ BFR. However, the technique did not increase the efficiency of dialysis.
