IntroductionExtracorporeal cardiopulmonary resuscitation (ECPR) may improve survival in refractory out-of-hospital cardiac arrest (OHCA) but also expand the donor pool as these patients often become eligible for organ donation. Our aim is to describe the impact of organ donation in OHCA patients treated with ECPR in a high-volume cardiac arrest centre.MethodsRate of organ donation (primary outcome), organs harvested, a composite of patient survival with favourable neurological outcome or donation of ≥1 solid organ (ECPR benefit), and the potential total number of individuals benefiting from ECPR (survivors with favourable neurological outcome and potential recipients of one solid organ) were analysed among all-rhythms refractory OHCA patients treated with ECPR between January 2013-November 2022 at San Raffaele Hospital in Milan, Italy.ResultsAmong 307 adults with refractory OHCA treated with ECPR (95% witnessed, 66% shockable, low-flow 70 [IQR 58-81] minutes), 256 (83%) died during hospital stay, 33% from brain death. Donation of at least one solid organ occurred in 58 (19%) patients, 53 (17%) after determination of brain death and 5 (1.6%) after determination of circulatory death, contributing a total of 167 solid organs (3.0 [IQR 2.5-4.0] organs/donor). Overall, 196 individuals (29 survivors with favourable neurological outcome and 167 potential recipients of 1 solid organ) possibly benefited from ECPR. ECPR benefit composite outcome was achieved in 87 (28%) patients. Solid organ donation decreased from 19% to 16% in patients with low-flow <60 min and to 11% with low-flow <60 min and initial shockable rhythm.ConclusionsWhen ECPR fails in patients with refractory OHCA, organ donation after brain or circulatory death can help a significant number of patients awaiting transplantation, enhancing the overall benefit of ECPR. ECPR selection criteria may affect the number of potential organ donors.Copyright © 2024 Elsevier B.V. All rights reserved.
