Impact of cardiopulmonary resuscitation on outcome of kidney transplantations from braindead donors aged ≥65 years

INTRODUCTION: Patients with a history of cardiopulmonary resuscitation (CPR) and subsequent brain death are frequently evaluated for organ donation. Whether kidneys from ≥65-year-old braindead donors with a history of CPR can be transplanted with satisfactory outcomes is unknown. MATERIAL & METHODS: All kidney transplants (KTs) from ≥65-year-old donors performed at our center from 1999 to 2018 (n = 185) were retrospectively analyzed and outcome was compared for KTs from donors with and without a history of CPR (n = 27 and n = 158, respectively). RESULTS: No significant differences in the incidence of delayed graft function (DGF) as well as 1- and 3-year graft function were observed between the CPR and the no-CPR group (DGF: 26.0% vs. 31.0%, p = .76; 1-year serum creatinine: 150.4 μmol/L vs. 177.0 μmol/L, p = .11; 3-year serum creatinine: 150.4 μmol/L vs. 168.2 μmol/L, p = .52, respectively). Death-censored graft survival was comparable after 1 and 5 years (CPR group: 81.5% and 76.7% vs. no-CPR group: 86.6% and 75.7%, p = .70). Likewise, patient survival was not significantly different. Multivariable Cox regression analysis also did not identify CPR as a significant risk factor for graft loss or death. CONCLUSION: Our study suggests that, following stringent donor selection, the outcome of KTs from ≥65-year-old braindead donors with and without a history of CPR is comparable.
