目的:探讨维持性血液透析(maintenance hemodialysis, MHD)患者动静脉内瘘血流量(arteriovenous fistula blood flow, AVFB)与透析中动脉压的相关性。方法:选取3家医院2016年1月至2019年1月利用动静脉内瘘行MHD的慢性肾衰竭患者150例作为研究对象，根据动静脉内瘘血流量测量值分为3组，不足600 ml/min为低流量组，600～1000 ml/min为中流量组，超过1 000 ml/min为高流量组。动静脉内瘘吻合术后随访20个月，观察不同组别患者透析过程中动脉压监测值和内瘘失功发生情况。结果:AVFB与透析中动脉压及内瘘失功呈负相关。结论:MHD患者动静脉内瘘使用过程中，需注意对血流量的动态监测，动静脉内瘘血流量控制在600～1 000 ml/min为宜，透析过程中动脉压监测值维持在-80～-120 mmHg为宜，可减少对内瘘功能的影响。“,”Objective:To explore the correlation between arteriovenous fistula blood flow (AVFB) and arterial pressure in maintenance hemodialysis (MHD) patients.Methods:A total of 150 patients with chronic renal failure who used arteriovenous fistula for MHD in 3 hospitals from January 2016 to January 2019 were selected as the research subjects. According to the blood flow of the arteriovenous fistula, the patients were divided into 3 groups, e. g.less than 600 ml/min was the low flow group, 600-1 000 ml/min was the medium flow group, more than 1 000 ml/min was the high flow group. The occurrence of arterial pressure monitoring value and internal fistula failure were observed duling 20-months follow-up.Results:AVFB was negatively correlated with arterial pressure during dialysis and internal fistula failure.Conclusion:During the use of arteriovenous fistula, we should pay attention to the dynamic monitoring of blood flow. It is advisable to control the arteriovenous fistula blood flow at 600 to 1 000 ml/min, and it is advisable to maintain the arterial pressure monitoring at -80 to -120 mmHg during dialysis, which can reduce the impact on the patient’s internal fistula function.
