Background:
Critical shortages of organs for transplantation jeopardize many lives. Observational data suggest that better fluid management for deceased organ donors could increase organ recovery. We conducted the first large multicenter randomized trial in brain-dead donors to determine whether protocolized fluid therapy increases the number of organs transplanted.
Methods:
We randomly assigned donors to either protocolized or usual care in eight organ procurement organizations. A "protocol-guided fluid therapy" algorithm targeting the cardiac index, mean arterial pressure and pulse pressure variation was used. Our primary outcome was the number of organs transplanted per donor, and our primary analysis was intention to treat. Secondary analyses included: (1) modified intention to treat where only subjects able to receive the intervention were included and (2) 12-month survival in transplant recipients. The study was stopped early.
Results:
We enrolled 556 donors: 279 protocolized care and 277 usual care. Groups had similar characteristics at baseline. The study protocol could be implemented in 76 % of subjects randomized to the intervention. There was no significant difference in mean number of organs transplanted per donor: 3.39 organs per donor (95 % CI 3.14-3.63) with protocolized care compared to 3.29 usual care (95 % CI 3.04-3.54; mean difference, 0.1, 95 % CI -0.25 to 0.45; p = 0.56). In modified intention-to-treat analysis the mean number of organs increased (3.52 organs per donor, 95 % CI 3.23-3.8), but not statistically significantly (mean difference, 0.23, 95 % CI -0.15 to 0.61; p = 0.23). Among the 1,430 recipients of organs from study subjects with data available, 56 deaths (7.8 %) occurred in the protocolized care arm and 56 (7.9 %) in the usual care arm in the first year (hazard ratio: 0.97, p = 0.86).
Conclusions:
In brain-dead organ donors, protocol-guided fluid therapy compared to usual care may not increase the number of organs transplanted per donor.
