摘　　要：目的:观察血流量正常的狭窄内瘘患者的再循环率与静脉穿刺点位置之间的关系。方法:对15例内瘘静脉有实质性狭窄而血流量正常的患者用彩色B超定位,在相邻的两次透析中分别选用下述不同的穿刺方法,并测定各自的再循环率进行相互比较:A:将静脉穿刺点选在内瘘狭窄处的近心侧。B:将静脉穿刺点选在狭窄的远心侧。结果:B穿刺法测得的再循环率R_B显著地高于A法的值R_A。结论:静脉穿刺点与内瘘狭窄部位之间的位置关系显著地影响了再循环率的测定。Objective: To observe the relationship between the recirculation rate and the location of venous puncture site in the stenotic fistula with normal blood flow.Method: Used color ultrasonic scan to mark the venous puncture sites in the 15 fistula stenotic patients different puncture sites were chosen in the following two consecutive hemodialysis sessions and the recirculation rates were measured respectively for later comparison: A.The venous puncture site was located at the side of the stenosis proximal to heart. B. The venous puncture site was Located at the side of the stenosis distal to heart. Results: The recirculation rate measured in site B (RB) was significantly higher than that in site A (RA) . Conclusion: Different venous puncture sites in stenotic fistula greatly affect the measurement of the recirculation rate.
