We examined factors affecting catheter Life Time during continuous renal replacement therapy (CRRT). A total of 617 cases in which either a conventional end-hole catheter (Gentle CathTM) or an elliptical end-hole catheter (Power Trialysis®) was used between January 2018 and December 2023 were included. The factors affecting Life Time included previously reported predictors of circuit coagulation and catheter type. Multiple Linear Regression analysis revealed that platelet count (Plt), activated partial thromboplastin time (APTT), soluble fibrin (SF), and catheter type were significantly associated with catheter Life Time, with the Power Trialysis® catheter showing an extended Life Time. Evaluation of the impact of these factors’ indicated that catheter type exerted the second-largest influence on Life Time, after Plt. These findings suggest that catheter type is an important determinant of Life Time during CRRT, with the Power Trialysis® catheter demonstrating the potential to extend Life Time.
