A native arteriovenous fistula (AVF) is recommended for angio access in patients on chronic hemodialysis (HD). Fistula patency has been improved by exposure to Far Infrared light (FIR).
To investigate whether a single FIR treatment could alter blood velocity, AVF diameter or inflammatory markers.
Thirty patients with a native AVF in the forearm were included. Each patient was his/her own control. Ultrasound (US) examinations were performed before and after a single FIR treatment.
A single FIR treatment resulted in a significant increase in blood velocity over the AV fistula from a mean of 2.1 ± 1.0 m/s to 2.3 ± 1.0 m/s (p = 0.02). The diameter of the arterialized vein became wider; 0,72 cm ± 0.02 to 0,80 cm ± 0.02, (p = 0.006). The increase in fistula blood velocity correlated positively with base line serum- urate p = 0.004) and the increase in venous diameter with the base line plasma orosomucoid concentration (p = 0.005).
This study shows that a single FIR treatment significantly increased AVF blood velocity and vein diameter. Thus, one FIR treatment can help maturation of AVF in the early postoperative course.
对于慢性血液透析（HD）患者，建议使用自体动静脉内瘘（AVF）作为血管通路。暴露于远红外线（FIR）可提高内瘘通畅率。
研究单次FIR治疗是否会改变血流速度、AVF直径或炎症标志物。
纳入30例前臂有自体AVF的患者。每位患者均以自身作为对照。在单次FIR治疗前后进行超声（US）检查。
单次FIR治疗使AVF的血流速度显著增加，从平均2.1±1.0米/秒增至2.3±1.0米/秒（p = 0.02）。动脉化静脉的直径变宽，从0.72厘米±0.02增至0.80厘米±0.02（p = 0.006）。内瘘血流速度的增加与基线血清尿酸呈正相关（p = 0.004），静脉直径的增加与基线血浆类粘蛋白浓度呈正相关（p = 0.005）。
本研究表明，单次FIR治疗可显著提高AVF的血流速度和静脉直径。因此，单次FIR治疗有助于术后早期AVF的成熟。
