Abstract

Background and Aim: One of the complications of using catheters is the occurrence of thrombosis, which can be dangerous for patients. The main objective of this study is to compare the effect of heparin, reteplase, and taurolock in the prevention of thrombosis in hemodialysis catheters. Methods: The present study is a clinical trial, in which the effect of three drugs, heparin, reteplase, and taurolock, in the prevention of thrombosis in hemodialysis catheters, has been investigated. The research units were studied in two intervention and control groups. The stratified random allocation method was used to assign patients to five groups (control, Heparin 50, Heparin 1000, reteplase, and taurolock), with strata based on the patient's age (20–70 years), gender, and duration of dialysis. Within each stratum, patients were also assigned to groups using the randomized block permutation method and a random number table tool. To prevent bias, this study is triple‐blinded. This means that the patient, the thrombosis assessor, and the statistical analyst are unaware of the type of intervention received by the patient. Results: Gender (p < 0.999), age distribution (p = 0.774), and duration of dialysis (p = 0.875) showed no statistically significant relationship with thrombosis. However, significant differences were observed among the five groups regarding thrombosis incidence. The relative risk of thrombosis in the Heparin 50, Heparin 1000, reteplase, and taurolock groups compared to the control group was 92.5%, 92.2%, 98.2%, and 89% lower, respectively. Conclusion: Our study underscores the efficacy of heparin, reteplase, and taurolock in preventing thrombosis in hemodialysis catheters. While all three drugs demonstrated efficacy, the Heparin 50 group exhibited the highest relative risk reduction. These findings suggest that heparin, particularly at a low dose, should be considered a standard prophylactic treatment in hemodialysis patients
