In refractory cardiac arrest, extracorporeal cardiopulmonary resuscitation may increase the survival chance. However, in cases of unsuccessful treatment, extracorporeal cardiopulmonary resuscitation may additionally provide an important source of organ donors. Therefore, we hypothesized that implementing extracorporeal cardiopulmonary resuscitation service into a high-volume cardiac arrest center’s routine would increases organ donors’ availability.

Our retrospective observational study analyzed out-of-hospital cardiac arrest patients admitted to the General University Hospital in Prague between 2007 and 2020.

The following groups were analyzed regarding the recruitment of donors: before and after extracorporeal cardiopulmonary resuscitation implementation. We assessed the number of donors referred, the number of organs harvested, and the organ’s survival.

We analyzed the results of 1,158 patients after out-of-hospital cardiac arrest. In the conventional approach period, 11 donors were referred, of which 7 were accepted. During the extracorporeal cardiopulmonary resuscitation period, the number of donors increased to 80, of whom 42 were accepted. The number of donated organs was 18 and 119 in the respective periods, corresponding to 3.6 vs 13.2 (p = 0.033) harvested organs per year. One-year survival of transplanted organs was 94.4% vs 99.2%, and 5-year survival was 94.4% vs 95.9% in relevant periods. Conventional and extracorporeal cardiopulmonary resuscitation did not affect donor organ survival.

Establishing a high-volume cardiac arrest center providing an extracorporeal cardiopulmonary resuscitation service may increase not only the number of prolonged cardiac arrest survivors but also the number of organ donors. In addition, the performances of donated organs were high and comparable between both treatment methods.
