血透患者踝肱指数测量时机的选择

Optimal timing of ankle-brachial index measurement in hemodialysis patients

目的探讨血液透析患者透析前及透析中测量踝肱指数(ankle-brachial index,ABI)的关联性。方法选取2016年6月在河南省人民医院维持性透析患者36例,每个患者进行两次ABI测量,分别为透析前15 min和透析开始后测量,收集患者临床资料,对两组ABI数据进行相关性分析。结果透析中测量开始的时间为透析开始后(92±15)min;右侧ABI透析前为1.12±0.15,透析中为1.13±0.17(P=0.504);左侧ABI透析前为1.10±0.16,透析中为1.11±0.15(P=0.166),两组间差异均无统计学意义;Pearson相关分析,左侧ABI r=0.940,右侧ABI r=0.916。结论透析中测量与透析前测量ABI有很好的关联性,可选择透析中进行测量。

Objective To investigate whether ankle-brachial index（ ABI） vary before hemodialysis（ HD） or during HD.Methods Thirty-six undergoing regular HD were enrolled. The ABI was measured 15 min before HD or during HD. Clinical data were collected. Pearson correlation coefficient analysis was performed to estimate the relationship between two groups.Results The HD measurement time was（ 92±15） minutes after initiation of HD. The right ABI before dialysis was（ 1. 12±0. 15）,and after HD was（ 1. 13± 0. 17）,P = 0. 504. The left ABI before HD was（ 1. 10 ± 0. 16）,and after HD was（ 1. 11±0. 15）,P = 0. 166. The two groups were no significant difference. Pearson correlation coefficient analysis,left ABI r was 0. 940,right ABI r was 0. 916. Conclusion ABI didn＇t vary at different measurement time points,it can be assessed during HD.
