Risk of heparin lock‐related bleeding when using indwelling venous catheter in haemodialysis

Abstract

A risk of inducing serious bleeding does indeed exist with Dual-Cath heparin locking, especially in postoperative patients. This risk can be reduced by measuring catheter length at the time of placement in order to ensure an appropriate lock volume. Sodium citrate, polygeline, or urokinase are possible alternatives to heparin.
