Systemic infusion of unfractionated heparin (UFH) is the standard anticoagulation technique for continuous renal replacement therapy (CRRT) during extracorporeal membrane oxygenation (ECMO), but often fails to avoid CRRT circuit clotting. The aim of this study was to assess, in patients undergoing CRRT during venovenous ECMO (vv-ECMO), the efficacy and safety of adding regional citrate anticoagulation (RCA) for CRRT circuit anticoagulation (RCA + UFH group) compared with the sole systemic heparin anticoagulation (UFH group). We performed a retrospective chart review (2009-2018) of patients treated with CRRT during ECMO. ⋯ No complication ascribable to citrate anticoagulation was recorded. Regional citrate anticoagulation resulted a feasible, safe, and effective technique as additional anticoagulation for CRRT circuits during ECMO. Compared with systemic heparinization only, this technique allowed to reduce the rate of CRRT circuit clotting.

Extracorporeal membrane oxygenation (ECMO) is a low-volume, high-risk modality of care. Clinical specialists (CS) who manage ECMO circuit emergencies vary in background and approach to circuit emergencies based on institutional training standards, leading to variation that may impact the quality of care. Validated checklists to assess CS performance are crucial to eliminate disparities and improve efficiency. ⋯ A Cronbach's α of 0.74 during the second round of responses indicated an acceptable degree of agreement. This study demonstrated content validation of three ECMO emergency checklists to assess performance of ECMO CS using a consensus-based Delphi technique. Future validity evidence should be acquired by implementing these checklists in the simulation environments.
