Regional Citrate Anticoagulation for Continuous Renal Replacement Therapy During Veno-venous ECMO: a Crossover Randomized Controlled Study

University of Milano Bicocca·interventional·Posted Dec 8, 2021·Updated May 7, 2026

In Brief

A clinical study evaluating Unfractionated heparin + RCA first and Unfractionated heparin first for ARDS, Human and Acute Kidney Injury. Completed, enrolled 18 participants across 1 site.

Detailed Summary

Anticoagulation is an essential component of all extracorporeal therapies. Currently locoregional citrate anticoagulation is the recommended technique for continuous renal replacement therapy (CRRT). However, low clearance of citrate restricts its use to blood flow up to 150 mL/min, preventing its use in ECMO. Renal replacement therapy (RRT) is commonly provided to ECMO patients with AKI. In presence of systemic heparinization for ECMO, additional anticoagulation for the CRRT circuit (i.e. RCA) is usually not employed. Nevertheless, thrombosis occurs more frequently in the CRRT circuit than the oxygenator because of the slower blood flow. The aim of this prospective, cross-over study is to assess, in patients undergoing CRRT during veno-venous ECMO (vv-ECMO), the efficacy and safety of adding regional citrate anticoagulation (RCA) for CRRT circuit anticoagulation.
