Infections of vector flow and palindrome catheters in permanent hemodialysis patients; epidemiology, surveillance, and evaluation during a 12-month period

Today, according to the high levels of chronic renal failure prevalence, the application of permanent catheters has been increased. Effective development and identification of influential factors can lead to the long-term usage of catheter, reduced complications and improved life quality in patients. The purpose of this study was to evaluate the infection ofVector flow and the Palindrome catheters during vascular access in permanent hemodialysis patients. This clinical trial study was conducted on 185 hemodialysis patients with a permanent catheter in the Imam Reza Hospital in Kermanshah, Iran (2018). The patients were randomly allocated to the Vector flow(n=76) and the palindrome (n=70) groups. Data analysis was performed using SPSS software and statistical tests. P-value < 0.05 were considered significant. Totally, of 185 hemodialysis patients (59.6%) were male and (44.5%) female (44.5%). The average survival of the Vector flow (52.1%) was 6.55 ± 3.88 for most patients, and the palindrome (47.9 %) was 5.22 ± 2.88. The survival rates of the Vector flow(6.55) were more than the palindrome was (5.22). Also, in this study, survival rates during 3 and 6 months follow-up, was more significant than the palindrome group (P = 0.049). Catheter removal due to infection was observed in 15 patients (P =1.0). In this study, factors of age, gender, out catheter infection did not affect the survival rates in both catheters. In this study,catheter function in the vector flow group was more significant than the Palindrome group. Results showed that different catheter such as shape, tip, and diameter, were not affected by the survival rates of the two types of catheters at 12 month. Also, factors such as infection age, gender, and occupation did not affect the survival rates of permanent hemodialysis catheters in the Vector flow and the palindrome.
