目的 探讨不同检测方法对透析器血室容积(TCV)检测值的影响.方法 对60支可重复使用的透析器(低通量透析器和高通量透析器各30支),按检测方法不同分为传统检测组、改良检测组和复用机检测组3组各20支,分别采用传统检测法、改良检测法和复用机检测法对透析器使用前、后行TCV检测,并对结果进行比较.结果 传统检测组、改良检测组和复用机检测组测量6LR透析器和17 R透析器TCV基础值分别为(100.10±0.25)ml、(100.13±0.50)ml、(102.00±1.41)ml和(113.67±1.30)ml、(118.67±1.30)ml、(119.93±1.77)ml;对重复使用后6LR透析器和17 R透析器进行TCV检测,检测值分别为(95.20±7.76)ml、(96.20±7.22)ml、(102.80±4.26)ml和(100.00±11.48)ml、(114.35±3.31)ml、(117.07±2.96)ml;改良检测组与传统检测组对重复使用高通量透析器TCV检测值的比较差异显著.结论 采用改良检测法对重复使用高通量透析器进行TCV检测,能提高TCV检测值的准确性.

Exploration of the method of testing total cell volume

Objective To explore the influence of different testing methods on detecting value of to-tal cell volume. Methods 60 reusable dialyzers(low-flux dialyzer and high-flux dialyzer were 30 respec-tively) were enrolled. They were divided into the traditional testing group, the modified testing group and the automatic dialyzer reuse group with 20 dialyzers in each group according to different detecting methods, the results underwent analysis. Results The basic total cell volume of the traditional testing group, the modified testing group and the automatic dialyzer reuse group were (100.10±0.25) ml, (100.13±0.50) ml and (102.00±1.41) ml in 6LR dialyzer, while in 17R dialyzer, they were (113.67±1.30) ml, (118.67±1.30) ml and (119.93±1.77)ml respectively. The total cell volume of the dialyzer reuse in the traditional testing group, the modified testing group and the automatic dialyzer reuse group were (95.20±7.76) ml, (96.20± 7.22) ml and (102.80±4.26) ml in 6LR dialyzer, while in 17R dialyzer, they were (100.00±11.48) ml, (114.35±3.31 ) ml and (117.07±2.96) ml respectively. There was significant difference between the tradi-tional and the modified testing groups in high-flux dialyzers reuse. Conclusions The modified testing method can improve the accuracy of the testing of total cell volume in high-flux dialyzer reuse.
