Abstract: Objective To evaluate the effect of far infrared radiation on the maturation of newly created arteriovenous fistula (AVF) in patients with end stage renal disease. Methods We enrolled 80 patients who were randomly allocated to the intervention group (n =40) or control group (n=40). The operations of arteriovenous
fistula formation were done by one surgeon. Far infrared radiation was used for the intervention group, 40 minutes 3 times weekly, but not for the control group. Blood flow in AVF (Qa) and fistula diameter were measured by Doppler ultrasonography after the surgery for 1, 2 and 3 months. The physiologically maturated
fistula was then used for dialysis, and the pump blood flow and puncture injury were observed. Results Compared the patients in control group, patients in the intervention group had higher Qa values after far infrared radiation for 2 months (525.4 ± 175.8ml/min vs. 487.8 ± 187.4ml/min; P=0.000) and 3 months (574.2 ± 204.3ml/min vs. 23.2±238.2ml/min; P=0.010). In addition, they had larger AVF diameters after far infrared radiation for 2 months (0.45 ± 0.12mm vs. 0.42 ± 0.11mm; P=0.040) and 3 months (0.47 ± 0.11mm vs. 0.43 ± 0.19mm; P=0.030), more physiological maturation rate (97.4% vs. 84.2%; P = 0.040) at 3 months, and higher clinical success rate (94.9% vs. 84.2%; P= 0.010) within 3 months. Conclusions Far infrared radiation improves blood access flow, and promotes maturation of newly created AVFs in patients with end stage renal disease.
