Femoral Localization and Higher Ultrafiltration Rate but Not Concentration of Heparin Used for Canal Locking of Hemodialysis Catheter Are Negative Predictors for Its Malfunction

Abstract

A lower concentration of heparin (2,500 IU/ml) prevents catheter thrombosis as effectively as a standard one (5,000 IU/ml). Femoral localization of HD catheters and higher UF during the HD procedure are the factors predisposing for catheter malfunction.
