Randomized Controlled Trial Clinical TrialA randomized trial of minidose warfarin for the prevention of late malfunction in tunneled, cuffed hemodialysis catheters.
Minidose warfarin (1 mg/day) has been associated with a 74% reduction in the thrombosis rate of central venous catheters used in oncology patients. To determine the efficacy of minidose warfarin on late malfunction caused by thrombosis or fibrin sheath formation in tunneled, cuffed catheters (TCC) used for hemodialysis (HD), we performed a randomized, placebo-controlled trial. ⋯ Thrombosis prophylaxis using fixed minidose warfarin is not efficacious in TCCs used for HD. However, the present data suggest improved TCC survival in patients with an INR> 1.00. Patients with diabetes and those with a low Hgb or INR have a higher risk of late TCC malfunction.
