Abstract
|
|
|
Objectives: To determine the safety and effectiveness of measurement of vascular access flow using thermodilution or
temperature gradient methods.
Methods: Database search was performed in 8 Korea databases, Ovid-MEDLINE, Ovid-EMBASE and Cochrane Library
until May 4th, 2015. 10 diagnostic evaluation studies were selected. Quality assessment and data extraction were performed by two reviewers.
Results: These methods are a noninvasive test using by blood temperature monitoring module of hemodialysis machine.
It doesn’t affect direct harm to patients as it conducted. The measurement accuracy was reported in 9 studies. These
methods are valid methods to estimate flow vascular access, because these methods showed good agreement and correlation with reference/comparator. The clinical influence was reported in 1 study. Receiver operating characteristic curve analyses confirmed flow measurement to be a useful predictor of fistula failure.
Conclusion: The agreement and correlation between these methods and reference/comparator is affordable. When used
for surveillance to vascular stenosis or vascular access failure, these methods are useful to monitor vascular access flow
trend with hemodialysis patient.
