Continuous veno-venous hemofiltration without anticoagulation in high-risk patients

Abstract: Critically ill patients at high risk of bleeding who require continuous renal replacement therapy (CRRT) can be safely managed without circuit anticoagulation. This strategy minimizes bleeding risks and is associated with an acceptable filter life. CRRT without anticoagulation should be strongly considered in high-risk patients.

“…Thus, the choice of the anticoagulant strategy, possibly limited to the extracorporeal circuit (i.e., regional anticoagulation), represents a key issue for safe and effective RRT in AKI. Although RRT can be performed without anticoagulation (8)(9)(10)(11), this approach increases the risk of delivering low RRT doses in up to 30% of patients (12) because of shorter circuit life, increased downtime, and reduced filter performance (12)(13)(14).…”

“…Despite comparable aPTT values, the filter run times in the heparin group were shorter than those reported in previous studies, where filter lives of between 14 and 24 hours were described. [13][14][15] It could be argued that the dimension of the beneficial effect of iloprost may not be of wider clinical relevance. One explanation for the shorter run times is that the run time of each filter for each patient was included in the calculation of filter patency.…”

“…Vários fatores podem influenciar a sobrevida do capilar e devem ser considerados especialmente nos pacientes críticos, nos quais a anticoagulação freqüentemente é contra-indicada. O fluxo da bomba de sangue deve ser o maior que for tolerado pelo paciente (150 mL/min), e o cateter deve estar totalmente permeável, para evitar aumento na pressão pós capilar de retorno (segmento venoso) e diminuir o número de complicações mecânicas como baixo fluxo no sistema (segmento arterial), situações que estão associadas ao aumento dos episódios de trombose 10,33 . Um estudo 33 mostrou que a sobrevida do filtro na TSRC sem o uso de algum esquema de anticoagulação é aceitável (cerca de 30 horas), com redução das complicações hemorrágicas e um adequado controle metabólico.…”
