- W1968038863 abstract "In this study, FLUENT (computational fluid dynamics software) is utilized to compare the performance of three widely used hemodialysis catheters, Niagara double lumen, Flexxicon II double lumen and Hemosplit long-term catheters of BARD Access Systems, in terms of blood flow rate and shorter exposure time. Running the three models at a fixed blood flow rate of 300 ml/min, it is found that Niagara catheter displays the lowest shear rates, yet high enough to induce thrombosis, which occurs as a result of platelet aggregation. High vorticity magnitudes exceeding 50,000s−1 are detected near the venous luminal walls of the Hemosplit catheter rendering the formation of Hemolysis which causes free toxic hemoglobin to circulate in the blood stream. Furthermore, the highest shear rates are found to occur at the arterial inlet, downstream the openings where inflow of blood occurs. It was found that the Niagara catheter, with open side holes, is the most recommended among the three considered catheters." @default.
