Haemodynamic management in brain death donors: Influence of aetiology of brain death

Improved Utilization Rate in Solid Organ Donors ≥80 Years: The 7-Year Tuscany Experience

INTRODUCTION

The Tuscany Region has a quite high annual number of donors per million population (100 donors/pmp (annually)). Considering the increasing donor age and organ shortage, the donation and transplantation community needs to expand procurement and transplants from elderly donors. We assessed the utilization rate in donors aged ≥80 years during the study period (2018-2024) in Tuscany.

METHODS

Our retrospective observational study comprised 809 donors aged ≥80 years. We compared Period 1 (from 2018 to 2020, before the COVID pandemic) to Period 2 (from 2021 to 2024, after the COVID pandemic).

RESULTS

cDCD donors significantly increased in Period 2 (0.0001). The utilization rate increased from Period 1 to Period 2 (81.5% vs. 91.7%). In the study period (2018-2024), 377 liver transplants were performed. Overall graft and patient survival at 1, 3, and 5 years when an octogenarian graft was used was 89.4%, 85.0%, 81.8% and 92.5%, 88.7%, 85.5%, respectively. EAD (early allograft dysfunction) was observed in 2.9% of the cases, and IC (ischemic cholangiopathy) developed in 6.3% of the cases. Forty kidneys were transplanted into 22 patients, including 18 dual kidney transplants.

CONCLUSIONS

During the 7-year study period, donors aged ≥80 years represented a consistent subgroup, since they accounted for one-third of the overall donor population. The increase in utilization rate observed during the study period may be related to several factors, both in the procurement and the transplant phase.

Active Donor Management Goals in Serial Donors After Brain Death

OBJECTIVES

Management of potential organ donors is crucial in the donation process, considering that hemodynamic instability is quite common.

MATERIALS AND METHODS

In the this single-center retrospective observational study, we analyzed 87 utilized brain death donors consecutively admitted to our intensive care unit from January 1, 2019, to December 31, 2022. We assessed the achievement of donor management goals during the observation period, and we also evaluated whether the achieve-ment of donor goals differed between younger and older donors (arbitrary age cutoff of 65 years).

RESULTS

In our series, mean age of donors was 67 ± 18 y, and organ-per-donor ratio was 2.3. The number of donor goals significantly increased during the 6-hour observation period (P < .001) and all donor goals were achieved in most donors (84/87) at the end of the observation period with no changes in the use and dose of vasoactive drugs. With respect to age, the number of donor goals was significantly higher in older donors at first evaluation, but goals significantly increased in both age subgroups of donors at the end of the 6-hour observation period.

CONCLUSIONS

Our data strongly suggested that a strict hemodynamic monitoring schedule allows the achievement of donor goals both in older and in younger brain death donors. We confirmed our previous findings that hemodynamic management in brain death donors is influenced by age. A strict hemodynamic monitoring schedule of brain death donors is useful to consistently achieve donor goals.
