Haemodialysis anticoagulation and adequacy

a. No clear differences in haemodialysis adequacy results have been demonstrated using standard unfractionated heparin and low molecular weight heparins. (Level II evidence, limited data) b. No differences in dialysis adequacy results are achieved using different low molecular weight heparins. (Level II evidence, limited data) c. There is no clear difference in the risk of thrombosis or haemorrhage with low molecular weight heparins compared with standard heparins, although the results of individual studies have been quite variable. (Level I evidence)
