Comparison between standard heparin and tinzaparin for haemodialysis catheter lock.

Tinzaparin offers some advantages over unfractionated heparin (UFH) for hemodialysis circuit anticoagulation. No study has compared these two molecules as hemodialysis catheter locks. This study aimed to compare the efficacy of tinzaparin and UFH as locks for hemodialysis tunnelled central venous catheter in patients with end-stage renal disease (ESRD).
