AbstractHuman organ transplantation has begun in the 1960s with donation after circulatory death. At that time this was named non heart beating donation, later donation after cardiac death and nowadays it is named donation after circulatory death. Currently, we are facing a significant shortage of transplant organs in Europe and worldwide. To increase the graft acceptance from donation after controlled or uncontrolled circulatory death, preceding regional normothermic perfusion by an extracorporeal circulation before organ procurement or ex-situ machine perfusion are frequently implemented in clinical practice as organ assessment and reconditioning techniques. Due to these advancements more organs can be potentially transplanted, even after out-of-hospital cardiac arrest (OHCA). First line actors like emergency physicians and pre-hospital paramedics must be aware of such programs to recognize and refer patients for donation in OHCA situations. This review provides an overview of organs transplanted from uncontrolled donation after circulatory death (uDCD) and emphasize the role of the emergency physician in the organ donation cascade. Outcome of uDCD has a lower effectiveness than donation after brain death (DBD) and controlled donation after circulatory death (cDCD) for short term graft survival. However, observational studies illustrate that long term outcome from uDCD is comparable to graft outcome from cDCD and DBD. We summarize the studies reporting the procured organ rate and functional outcome of organs originated from uDCD. European databases indicate a high incidence of OHCA, where resuscitation efforts are initiated but the rate of return of spontaneous circulation (ROSC) remains limited. These patients represent a substantial potential pool of organ donors for uDCD programs. However, these programs tend to overestimate the number of potential donors. While organ procurement from uDCD has yielded favorable outcomes, further research is required to accurately assess the associated costs and benefits and to establish clear donor selection guidelines. Furthermore, the use of new technologies like extracorporeal Cardiopulmonary Resuscitation (E-CPR) for organ donation should be investigated from both medical and economical perspectives. Emergency departments must also explore the feasibility of implementing these programs.© 2024. The Author(s).
