Kidney Donation after Cardiac Death in Korea

Organ donation after cardiac death (DCD) has been suggested due to the shortage of allografts in Korea. We investigated the outcomes of 446 deceased donor kidney transplant recipients in our center between September 1, 1995, and December 31, 2009. Twenty-four (5.4%) of those patients received DCD kidney grafts. The DCD group had a long intensive care unit stay, frequent inotropics use (such as norepinephrine and dopamine), low mean blood pressure and estimated glomerular filtration rate, and high serum creatinine and deceased donor scores compared to the standard criteria donor (SCD) group and the expanded criteria donor (ECD) group. Mean true warm ischemic time of the DCD group was 59.7 minutes based on asystole time. The DCD group had a long hospital stay after transplantation, but there was no statistically significant difference in delayed graft function and primary nonfunction. Serum creatinine levels at 3 months after transplantation in the ECD and DCD group were significantly higher than the SCD group (P < .001) but lower in the DCD group than in the ECD group at 6 months and 9 months (P < .001 and P = .004) posttransplantation. There were no statistically significant differences in serum creatinine levels or in the graft survival rates between groups at 12 months (P = .160 and P = .737). The use of DCD attracted Korean surgeons because DCD allografts are equivalent to a heart-beating donor. Donors who die during the evaluation of brain death should not be abandoned for procurement, and we need to try to harvest allografts after cardiac death (type 4 DCD) to expand donor pools.
