rate was between 220-300 mL/min with a mean of 271 ±
18.91 mL/min (Table 1).
The mean blood urea nitrogen (BUN) before low-flux
dialysis was 93.90 ± 20.51 mg/dL, which reduced at the
end of the dialysis to 36.87 ± 13.16 mg/dL. The observed difference
was statistically significant, (P < 0.001). Furthermore,
the mean of the BUN before high-flux dialysis was
95.32 ± 19.69 mg/dl, which reduced to 32.35 ± 8.83 mg/dL
at the end of dialysis, which was statistically significant (P
< 0.001) (Table 2).
The mean of BUN before using the low-flux, (93.90 ±
20.51 mg/dL) and high-flux membrane (95.32 ± 19.69 mg/
dL) were not significantly different (P = 0.725). Although
the mean of BUN after high-flux dialysis (32.35 ± 8.83 mg/
dL) was lower than the mean of the BUN after low-flux dialysis
(36.87 ± 13.16 mg/dL), this difference was not statistically
significant (P = 0.071) (Table 2).
The URR was 60% to 80% for half of the patients in lowflux
dialysis; whereas, 70% of the patients in high-flux
dialysis had the URR of 60% to 80%. The mean of URR for
patients in low-flux dialysis was 0.65 ± 0.14, and in the
high-flux dialysis was 0.65 ± 0.09. Although the adequacy
of dialysis based on URR was higher in the high-flux dialysis,
the difference was not statistically significant (P =
0.211) (Table 3).
In high-flux dialysis, the most frequent (32.5%) of KT/V
was 1.2 to 1.4 (mean 1.27 ± 0.28); while, in low-flux dialysis
the most frequent (30%) of KT/V was 1 to 1.2 (mean 1.1
± 0.32); these differences was statistically significant (P
= 0.017) (Table 4), which reveals the relative adequacy of
high-flux dialysis.
