摘要： 【摘要】目的调查血液透析过程中泵前动脉压与泵控血流量比值的正常范围并探讨其临床意义。方法纳入2 家三甲医院的血液透析患者527 例，收集透析治疗过程中每个小时的泵前动脉压、静脉压、跨膜压等压力检测指标及泵控血流量情况，并分析泵前动脉压(pre-pump arterial pressure，PreAP)绝对值与泵控血流速(blood flow rate, BFR)的相关性及其比值的95%参考值范围。结果泵前动脉压绝对值与泵控血流量呈显著正相关性(b=10.09, t=65.241, Ptrend＜0.001)；PreAP 绝对值与BFR 比值的水平为(0.43±0.12)，95%参考值范围为(0.20，0.66)。结论明确PreAP 与BFR 比值的参考范围可以早期发现和预防内瘘狭窄的发生，为临床护理提供快速筛查的手段，为持续监测和早期干预提供理论依据。当比值持续超出95%参考值范围，提示血管通路功能可能欠佳，需要仔细评估血管通路是否存在狭窄。

Abstract:

【Abstract】Objective To investigate the normal range of the ratio of pre-pump arterial pressure (PreAP) to blood flow rate (BFR) during hemodialysis and to explore its clinical significance. Methods A total of 527 patients with hemodialysis from two tertiary hospitals were enrolled. The pressure measurement indexes of PreAP, venous pressure, transmembrane pressure and BFR were collected every hour in the dialysis session. The correlation of PreAP and BFR, and the 95% reference range of PreAP to BFR ratio were analyzed. Result The absolute value of PreAP was significantly correlated with BFR (b=10.09, t=65.241, Ptrend＜0.001). The statistical description of the absolute value of PreAP to BFR ratio was 0.43±0.12, and the 95% reference range was 0.20, 0.66. Conclusion Defining the reference range of PreAP to BFR ratio can early detect and prevent the stenosis in internal fistulas, and provide a rapid screening tool for clinical care and a theoretical basis for continuous monitoring and early intervention. The ratio continuously to exceed the 95% reference range suggests the poor function of vascular access, requiring to carefully examine whether stenosis is present in the vascular access.
