Abstract:
Objective: To study the application of glucose infusion test (GIT) in assaying the vascular access recirculation rate in hemodialysis patients. Methods: Access recirculation was assayed by both urea test (UT) and GIT in 82 hemodialysis patients, and 17 patients were also examined by Doppler ultrosonics method. The results of the Doppler ultrosonics were compared with those of UT and GIT. Results: Thirty-seven (45.12%) patients showed positive results with GIT and 29 patients (35.36%) with UT.All 17 patients had recirculation confirmed by Doppler ultrosonics and all had positive results by GIT (100%), but only 9 (52.94%) of the 17 patients had positive results by UT. Conclusion: Comapared with UT, GIT is more sensitive, more ecnomical,and simpler in determining vascular access recirculation, and can be used as a new method for screening vascular access recirculation.
