Brain Reperfusion Or Regain Of Brain Function During Normothermic Regional Perfusion

The aim of this study is to demonstrate that cerebral blood flow and brain function do not resume after death declaration in organ donors who undergo normothermic regional perfusion to restore organ function following death determination by circulatory criteria, when appropriate safeguards are applied. To assess the absence of cerebral perfusion and function, investigators will use continuous and comprehensive multimodal neuromonitoring throughout the withdrawal of life-sustaining therapies, the dying process and the NRP procedure.
