不同动静脉内瘘穿刺间距对维持性血液透析患者透析充分性的影响

Effect of different puncture distances in internal arteriovenous fistula on dialysis adequacy in maintenance hemodialysis patient

目的探讨不同动静脉内瘘穿刺间距对维持性血液透析患者透析充分性的影响。方法根据行血液透析时间的先后次序,将120例维持性血液透析患者分为观察组和对照组,每组各60例,观察组患者穿刺时增加动静脉内瘘的穿刺距离,穿刺距离相距10 cm以上;对照组采用传统方法进行穿刺,未增加穿刺间距。比较两组患者干预前后透析充分性差异。结果干预后观察组患者透析充分性优于对照组和干预前(P<0.05)。结论增加动静脉内瘘的穿刺距离可以提高维持性血液透析患者的透析充分性。

Objective To investigate the effect of different puncture methods on dialysis adequacy in maintenance hemodialysis patients. Methods One hundred and twenty patients receiving maintenance hemodialysis were divided into the observation group and the control group according to the sequence of receiving the hemodialysis with 60 cases in each group. Patients in the observation group were treated with increasing distance arteriovenous fistula of more than 10 cm, while patients in the control group received normal dialysis care without changing the way of puncture. The difference of dialysis adequacy before and after intervention were compared between the two groups. Result The dialysis adequacy after intervention in the observation group was improved significantly compared with the control group（P〈0.05）. Conclusion The dialysis adequacy in patients with maintenance dialysis can be improved by increasing the puncture distance of internal arteriovenous fistula.
