Purpose: This study aimed to determine whether the direction of arterial needle insertion and the bevel orientation during arteriovenous fistula (AVF) cannulation affect the recirculation rate and dialysis adequacy, thereby providing evidence relevant to dialysis nursing care. A single-group pretest-posttest design was employed. Methods: This study included 54 hemodialysis patients at Hallym University Sacred Heart Hospital from July 24 to September 16, 2023. Eligibility criteria included age ≥ 18, AVF use for ≥ 3 months, no recent vascular interventions, and AVF blood flow ≥ 600 mL/min. The recirculation rate was measured with an HD03 monitor at 2-2.5 hours post-initiation, and dialysis adequacy was assessed via Kt/V. The paired t-test was used for analysis. Results: Among 54 participants, 57.4% were male, and 57.4% had been receiving hemodialysis for ≤ 5 years. The mean AVF blood flow was 982.52 mL/min. No significant differences in the recirculation rate or dialysis adequacy were found based on needle direction or bevel orientation. Conclusion: The findings suggest that arterial needle direction and bevel orientation during AVF cannulation do not significantly impact the recirculation rate or dialysis adequacy. These results support the standardization of AVF cannulation techniques, which would not pose concerns for altering dialysis efficiency. Further studies with larger samples are recommended.
