Aim. Donor warm ischaemic time is identified as the main risk factor for poor outcomes in liver transplantation using donation after circulatory death (DCD) compared to using donation after brain death (DBD). However, benefits of minimizing this time has not been systematically explored. Therefore, we sought to investigate the influence of location of donor life support withdrawal, in either the intensive care unit (ICU) vs. operating theatre (OT) on outcomes. We additionally examined potential benefits of ante-mortem administration of heparin due to its proposed role in reducing micro-thrombi in DCD livers. Methods. A systematic search was conducted through EMBASE, Medline and Cochrane libraries and 23 studies were included for synthesis. Results. Compared to DBD recipients, one-year patient mortality (OT withdrawal: OR = 1.2, 95% CI 0.85-1.68; ICU withdrawal: OR = 2.15, 95% CI 1.15-4.02), one year graft loss (OT: OR = 1.65, 95% CI 1.16-2.36; ICU: OR = 1.98, 05% CI 1.13-3.47) and incidence of ischaemic cholangiopathy (OT: OR = 13.73, 95% CI = 5.18-36.44; ICU: OR = 19.68, 95% CI 7.48-51.75) were all reduced by withdrawal in OT compared to in ICU. Furthermore, the incidence of primary non-function was reduced by administration of heparin to the donor prior to withdrawal of life support (heparin: OR = 3.48, 95% CI 1.79-6.76; no heparin: OR = 11.24, 95% CI 1.99-63.37). Conclusions. Our evidence suggests that withdrawal of life support in the OT can confer significant benefits to outcomes for the recipients, thus facilitating optimal usage of these valuable organs. As such we recommend further evaluation of the outcomes from active withdrawal in the OT and ante-mortem administration of heparin.
