Multicenter prospective observational study on safety and efficacy of regional citrate anticoagulation in CVVHD in the presence of liver failure: the Liver Citrate Anticoagulation Threshold Study (L-CAT)

Regional citrate anticoagulation in continuous venovenous hemodialysis (citrate-CVVHD) has become a widely used technique in the ICU, which decreases risk of bleeding. However, concern exists about safety of citrate in liver failure patients. The aim of our study was to evaluate safety and efficacy of regional citrate anticoagulation in ICU patients with normal and impaired liver function.
