H₂S-Enriched Flush out Does Not Increase Donor Organ Quality in a Porcine Kidney Perfusion Model.

ABSTRACT: Kidney extraction time has a detrimental effect on post-transplantation outcome. This study aims to improve the flush-out and potentially decrease ischemic injury by the addition of hydrogen sulphide (H₂S) to the flush medium. Porcine kidneys (n = 22) were extracted during organ recovery surgery. Pigs underwent brain death induction or a Sham operation, resulting in four groups: donation after brain death (DBD) control, DBD H₂S, non-DBD control, and non-DBD H₂S. Directly after the abdominal flush, kidneys were extracted and flushed with or without H₂S and stored for 13 h via static cold storage (SCS) +/- H₂S before reperfusion on normothermic machine perfusion. Pro-inflammatory cytokines IL-1b and IL-8 were significantly lower i
