ABSTRACT
PURPOSE:
Vascular access flow (Qa) measurements are important in the surveillance protocol of hemodialysis vascular access stenosis. The glucose pump technique (GPT) is a technique for Qa measurement based on the dilution technique of a constant glucose infusion that was introduced in 1995. The aim of this study is to verify the clinical efficacy of GPT in vascular access surveillance compared with ultrasound dilution technique.METHODS:
In 31 chronic hemodialysis patients with a AV fistula, we compared Qa measurements performed with GPT in pre-dialysis and the ultrasound dilution technique (Transonic HD01, Transonic System Inc., Ithaca, NY) during hemodialysis.RESULTS:
Mean Qa was 1171 ml/min by GPT versus 1028 ml/min by HD01 (p=0.262). There was a strong linear correlation between the two methods (r=0.61; p<0.01). Ultrasound dilution technique HD01 yielded 6 cases of high risk Qa measurements and GPT yielded 4 cases of high risk Qa measurements. The diagnostic accuracy of GPT tested with the ROC curve was similar with ultrasound dilution technique HD01. The specificity and sensitivity was 80% and 66.7% according to Qa=600 ml/min. But sensitivity was 83.3% according to Qa=750 ml/min.CONCLUSION:
GPT offers the advantage of a simple and economic bedside procedure easily performed before dialysis and had a similar diagnostic accuracy and efficiency compared with ultrasound dilution technique HD01.
