Abstract
Aim: This study, concerning the risk factors of thrombosis on tunneled double-lumen catheters with administration of Heparin locking solution at Prof. Dr. I.G.N.G Ngoerah Hospital, supports the expansion of knowledge in addressing vascular access challenges in Stage V Chronic Kidney Disease patients. Method: Conducted from August 1, 2022, to August 31, 2023, employing a bidirectional cohort study design, analyzing 73 Stage V CKD patients. Among these patients, vascular location, insertion side, and dialysis frequency were assessed. Results: The findings indicate that vascular location, insertion side, and dialysis frequency are not thrombosis risk factors for tunneled double-lumen catheters. Conversely, protective associations were observed for jugular vein location (RR 0.413), right-side insertion (RR 0.42), and twice-weekly hemodialysis (RR 0.388). Analysis of tip position showed a weak negative correlation with thrombosis risk. Conclusion: The study concludes that vascular location, insertion side, and hemodialysis frequency are not thrombosis risk factors, revealing significant protective associations for these variables.
