Analysis of organ procurement from non-heart-beating donors over a 10-year period in Madrid.

Objectives: The Autonomous Community of Madrid procures the largest number of organs from uncontrolled non-heart-beating donors (NHBD) after circulatory death in Spain. The aim of this study was to analyze the yield of these donations in terms of viable organs procured (category IIa) according to information extracted from the CORE registry of the Spanish National Transplant Organization (ONT) for the Madrid area.
Methods: Retrospective observational study of NHBD data registered between 2007 and 2017, including age, height, weight, body mass index (BMI), emergency care times, method of chest compressions applied (mechanical cardiopump vs manual compressions), and viable organs extracted.
Results: A total of 679 circulatory death donors were registered; 458 (67.6%) of them were utilized donors. The median BMI correlated negatively (-0.161) with the number of viable organs extracted (P<.001). The method of applying chest compressions significantly influenced liver viability: only those extracted after mechanical cardiopump compressions were viable for transplantation. Type of compressions did not effect kidney or lung viability.
Conclusion: Variables to bear in mind as predictors of success in NHBD donation are BMI and type of chest compressions applied.
