Abstract
Background<br/>Normothermic regional perfusion (NRP) is a novel technique that aids organ recovery from donors after circulatory death (DCDs). However, ethical concerns exist regarding the potential return of spontaneous cerebral and cardiac activity (ROSCCA). This study aimed to determine the likelihood of ROSCCA in NRP‐DCDs of abdominal organs.<br/><br/>Methods<br/>Extracorporeal cardiopulmonary resuscitation (ECPR) for refractory out‐of‐hospital cardiac arrest (OOHCA) was identified as a comparator for NRP‐DCDs and as a validation cohort. A systematic search identified all articles relating to NRP‐DCDs and ECPR‐OOHCA. Rates of ROSCCA and survival outcomes (ECPR‐OOHCA only) were recorded and analysed according to the duration of no perfusion.<br/><br/>Results<br/>In NRP‐DCDs, 12 of 410 articles identified by database searching were eligible for inclusion. There were no instances of ROSCCA recorded among 493 donors. In ECPR‐OOHCA, eight of 947 screened articles were eligible for inclusion (254 patients). Where the absence of perfusion exceeded 5 min in ECPR‐OOHCA, there were no survivors with a favourable neurological outcome.<br/><br/>Conclusion<br/>ROSCCA is unlikely following commencement of NRP and has not occurred to date. Strict observance of the 5‐min interval following asystole provides satisfactory assurance that ROSCCA will not occur following NRP.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
