动静脉内瘘使用平行向心性穿刺法建立血液净化血管通路的效果

Effect of parallel axipetal centesis in vascular access setting-up

目的比较平行向心穿刺法和传统穿刺法在透析效率方面的差异，探讨其可行性与有效性。方法采用自身对照方法，观察维持性血液透析患者30例，分别采用平行向心穿刺法和传统穿刺法建立血管通路，比较2种穿刺方式对透析效率的影响。结果2种穿刺方法均可达到有效透析血流量，透析前后尿素、肌酐、尿酸及磷的下降率和Kt／V差异无统计学意义（P〉0．05）。结论平行向心穿刺法较之传统穿刺法具有诸多优点，且能保证透析效果，是一种更为理想的新型血液透析穿刺方法。

Objective To compare the parallel axipetal centesis with traditional centisis in hemodialysis efficiency, and discuss the practicability and effectiveness. Methods 30 patients with maintenance hemodialysis were involved. Parallel axipetal centesis and traditional centesis were applied by means of self control and hemodialysis efficiency was compared. Results Effective blood flow could be achieved with both centesis methods. There was no significant difference of the rate of descend in blood urea, creatine, uric acid and phosphorus and Kt/V between the two groups （P 〉 0. 05 ）. Conclusions Parallel axipetal centesis has numerous advantages compared to traditional eentesis, and the hemodialysis efficiency remains high. Thus the parallel axipetal centesis is an ideal new-style centesis for hemodialysis.
