Arteriovenous Fistula Recirculation and its Relationship with Some Factors in Hemodialysis Patients

Recirculation rate is essential for the quality of Hemodialysis. Since the treatment of patients is based on the Dialysis Adequacy, the evaluation of recirculation is especially important. This study was performed with the aim of measuring arteriovenous fistula recirculation and its relationship with some factors in Hemodialysis patients. In this Descriptive-Analytical study, all Hemodialysis patients (n=100), in Panje Azar Hospital of Gorgan, whose vessels were accessed by arteriovenous Fistula was studied in the summer of 2009. In order to determine recirculation rate، we used urea based classic method. The cut point of recirculation was considered 10%. The variables studied are Fistula longevity، direction of needle insertion، the space between needles and the place of needles fistula and KUF filteration. Data were analyzed by using descriptive statistics and logistic regression test (odds ratio and ci reported) in the SPSS software. Patients were male (53) and female (47) with the mean age of 50. 93± 17. 23. The mean year of Dialysis history was 4. 04 ± 5. 04. Fifteen percent of patients had recirculation. Average access recirculation of all patients was 0. 067 ± 0. 118. Recirculation rate had significant relationship (P <0­. ­05) with direction of two Arterial-Venous needle and the place of the two needles، which may have been higher. Considering the results of this study, we conclude that emphasis should be applied on instructing correct needle insertion in order to decrease recirculation
