Abstract

BACKGROUND

It is important to know the relative clearances obtained when using single-needle versus double-needle cannulation techniques.

METHOD

Twelve hemodialysis treatments were conducted using a machine that is capable of single-needle as well as double-needle cannulation. Single-needle and double-needle blood flow rates, as well as urea clearance, were compared.

RESULTS

The measured blood flow rates were 368 ± 11 ml/min, 294 ± 4 ml/min, 200 ± 0 ml/min, and 100 ± 0 ml/min during double-needle hemodialysis and were 201 ± 10.9 ml/min, 173 ± 44.9 ml/min, 103 ± 4.1 ml/min, and 45 ± 4.9 ml/min during single-needle hemodialysis. The hemodialysis urea clearances at similar blood flow rate (approximately 200 ml/min) were 167 ± 4 ml/min and 161 ± 9 ml/min (paired t test; p > 0.05), respectively.

CONCLUSION

The measured blood flow rates and urea clearances during single-needle hemodialysis were approximately half of the measured blood flow rate during double-needle hemodialysis, and should be used in selected settings.

摘要

背景

了解使用单针与双针插管技术时获得的相对清除率很重要。

方法

使用一台能够进行单针和双针插管的机器进行了12次血液透析治疗。比较了单针和双针的血流速率以及尿素清除率。

结果

在双针血液透析期间测得的血流速率分别为368±11毫升/分钟、294±4毫升/分钟、200±0毫升/分钟和100±0毫升/分钟，在单针血液透析期间分别为201±10.9毫升/分钟、173±44.9毫升/分钟、103±4.1毫升/分钟和45±4.9毫升/分钟。在相似血流速率（约200毫升/分钟）下的血液透析尿素清除率分别为167±4毫升/分钟和161±9毫升/分钟（配对t检验；p>0.05）。
