[Enoxaparin in the prevention of thrombosis of extracorporeal circulation during dialysis of patients with chronic renal failure]. / L'enoxaparine dans la prévention de la thrombose du circuit extracorporel de dialyse des insuffisants rénaux chroniques.

Chronic renal failure patients under haemodialysis are exposed to two dangers: haemorrhage and clotting of the extracorporeal circulation circuit. This problem can be solved by using low molecular weight heparins. Two studies were conducted to evaluate the effectiveness and safety of a low molecular weight heparin: enoxaparin. The first study, which involved 42 chronic renal failure patients under haemodialysis without any particular risk, enabled the optimum dosage (1 mg/kg bodyweight) to be determined. The second study, which concerned 46 patients at high risk of haemorrhage who received enoxaparin 0.5 mg/kg or 0.75 mg/kg depending on the vascular approach, confirmed that enoxaparin was highly effective (clotting of the extracorporeal circuit in only 0.6 p. 100 of the cases) and well tolerated (bleeding in only 0.2 p. 100 of the cases).
