Objective To analyze the influence of different vascular access on the purification effect and safety of maintenance hemodialysis (HD) patients. Methods 60 patients who received HD treatment in our hospital from January 2023 to December 2024 were selected and divided into observation group and control group according to the principle of object matching, with 30 patients in each group. The control group used the internal jugular vein with tunnel dacron catheter (TCC) vascular access, while the observation group used the autologous arteriovenous fistula (AVF) vascular access, and compared the dialysis effect and other indicators between the two groups. Results The urea clearance rate (URR) and urea clearance index (Kt/V) in the observation group were higher after one month of dialysis treatment (P<0.05). After the intervention, the levels of inflammatory indexes and the incidence of complications in the observation group were lower (P < 0.05). Conclusion Using AVF to construct vascular access of HD patients can improve the dialysis effect, promote the adequacy of blood purification, alleviate inflammatory reaction and improve prognosis, and has good application value.
