Outcome of Cuffed Tunneled Dialysis Catheters for Hemodialysis Patients at a Tertiary Care Hospital: A Descriptive Cross-sectional Study

Abstract

Introduction: Arteriovenous fistula is the most common vascular access for patients requiringhemodialysis, but it is not always possible or practical hence cuffed tunneled dialysis cathetercomes into play. The aim of the study was to determine the outcome of cuffed tunneled dialysiscatheter used for hemodialysis at a teaching hospital. Methods: A descriptive cross-sectional study was conducted between January 2014 and December2019 on 103 chronic dialysis patients with end-stage renal disease presenting to a tertiary carehospital. Ethical approval was received from the institutional review board (2/(6-11) E2/076/77).Whole sampling was done. Data entry and analysis were done in Microsoft Excel 10. Results: The study included 103 patients with 117 cuffed tunneled dialysis catheters placed forhemodialysis. On assessing the outcome of the catheters, the primary and secondary patencyrates of the catheters were 5.85±4.87 and 1.21±3.77 months. Thirty-one (30.1%) patients requiredone intervention, and 11 (10.68%) catheters required 3 or more interventions to maintain patency.Eighteen (17.48%) patients presented with catheter dysfunction while in 11 (10.68%) cases, thecatheter was kinked or malpositioned at the notch. In one patient, procedure was abandoned dueto severe bleeding and in 2 (1.94%) patients dialysis catheters could not be negotiated into the rightatrium and left in brachiocephalic junction. Conclusions: Cuffed tunneled dialysis catheter is effective for maintenance hemodialysis in patientswith the end-stage renal disease if used with proper care during dialysis even in our setup. Theresults and outcomes of the procedure are at par with standards.
