Feasibility and performance of a combined extracorporeal assisted cardiac resuscitation and an organ donation program after uncontrolled cardiocirculatory death (Maastricht II).

INTRODUCTION

Approximately 500.000 people in Europe sustain cardiac arrest (CA) every year, being myocardial infarction the main etiology. Interest has been raised in a new approach to refractory cardiac arrest (rCA) using extra-corporeal oxygenation (ECMO). In settings where it can be rapidly implemented, ECMO assisted resuscitation (ECPR) may be considered. Additionally, donation after circulatory death, which seeks to obtain solid organs donation from patients suffering rCA, has increased its role effectively increasing the pool of donors. Combined programs with integration of ECPR and uncontrolled donation after circulatory determination of death (uDCDD) are worldwide limited and experience integrating these two techniques is lacking.

METHODS

We report a 24 months experience of ECPR and uDCDD kidney transplantation based on a management protocol in a university teaching hospital in the urban area of Lisbon.

RESULTS

Over a period of 24 months, 58 patients were admitted to our ICU with rCA, 6 (10%) in the ECPR program and 52 (90%) in the uDCDD. Seventy-eight percent of patients were male, with an average age of 49 year-old. CA was witnessed in 83% of cases and initial rhythm was ventricular fibrillation in 20 cases (35%). 13 (25%) patients were effective organ donors. Refusal for effective donation was mainly due to prior comorbidities.

DISCUSSION

The development of an integrated program for ECPR and uDCDD is feasible and requires a well-established and efficient activation program. In an era of significant organ shortage, it provides a viable option for increasing the organ donation pool, with promising results.
