“…9,15 As discussed above, in patients with renal failure the half-life of LMWH is prolonged, which might induce a state of excessive anticoagulation with increased risk of hemorrhagic events. 10,28,29,38,39 Another point to consider is that few amounts of LMWH are removed by the dialyzer during continuous dialysis. This hypothesis is supported by Singer et al, 24 who measured LMWH concentration and anti-factor Xa in plasma and in ultrafiltrate, showing that removal of LMWH by the dialysis filter was insignificant, which could result in drug accumulation.…”

“…10 This might suggest the need to monitor its anticoagulant effect by plasma anti-factor Xa activity. 11 Another important aspect is the lack of an effective antagonist to reverse the anticoagulant effect of LMWH, since protamine has only partial action.…”

“…First, in CKD grade III-V, LMWHs have prolonged half-lives leading to major haemorrhages when fixed dose schedules are employed without appropriate dose reduction. 4 Second, unlike conventional anticoagulants, effects of which can be readily reversed using protamine/FFP/vitamin K, effects of LMWH do not as readily reverse owing to lack of …”

“…Em pacientes criticamente enfermos, especialmente aqueles com insuficiência renal, a farmacocinética das HBPMs está alterada, observando-se prolongamento importante de sua meia vida [20][21][22] . Alguns estudos mostram um aumento significativo na incidência de sangramento em pacientes com insuficiência renal utilizando alguma HBPM 23,24 , justificando a dosagem do fator anti-Xa para monitorizar a atividade antitrombótica da droga. Entretanto, esse controle laboratorial (atividade do fator anti-Xa) não está disponível na grande maioria dos centros, principalmente pelo elevado custo da técnica, o que resulta em considerável aumento dos gastos da terapia dialítica 25 .…”
