Abstract

Background: The efficiency of hemodialysis (HD) relies on the success and quality of the access of the vascularity, which could be an arteriovenous (AV) fistula, an AV graft, or a central venous catheter (CVC). Objectives: This work compared AV fistulas and tunneled HD catheters in dialysis efficiency. Methods: This observational analytical cross-sectional study was conducted on 100 subjects aged 21-60, both genders, with end-stage renal disease (ESRD) who had been on regular HD for more than six months. Subjects were divided into two groups equally: Group A: ESRD with an AV fistula group and Group B: ESRD with a tunneled HD catheter group. Results: Malfunction times, infection attacks, and hospitalization were significantly decreased in the AV fistula group compared to the tunneled HD catheter group (P <0.05). Urea clearance and urea reduction ratio were significantly greater in the AV fistula group compared to the tunneled HD catheter group (P<0.001). The blood flow rate was significantly greater in the AV fistula group compared to the tunneled HD catheter group (P <0.001). Pre-dialysis urea and post-dialysis urea were significantly decreased in the AV fistula group compared to the tunneled HD catheter group (P<0.05). Subjective global assessments (SGA score) and ultrafiltration rate were insignificantly varied among the two groups. Conclusion: Tunneled HD catheter implants for maintenance HD are correlated to an elevated risk of all-cause mortality contrasted to individuals with AV fistula. Patients with AV fistulas had reduced hospital stays, decreased mortality, and improved laboratory results compared to patients with tunneled HD catheters.
