文摘
Despite important advances in the care of postcardiac arrest patients, severe brain injury remains one of the major causes of death in the cardiac intensive care unit. Neurological prognostication after cardiac arrest has evolved significantly since the introduction of therapeutic hypothermia. It now relies on a multimodal approach and a minimal observation period of 72 hours is usually advocated. However, when brain injury is severe and the prognosis considered dismal, patients become eligible for organ donation. Patients with severe anoxic encephalopathy might evolve toward brain death and be candidates for donation after brain death. In the presence of severe brain injury without brain death criteria, when withdrawal of life-sustaining therapy is considered, patients might be eligible for donation after cardiocirculatory death. The diagnosis of brain death, the differences between donation after brain death and donation after cardiocirculatory death, family approach, and donor management in the intensive care unit are discussed. Because these are increasingly encountered situations in the cardiac intensive care unit, it is essential that physicians involved in cardiac critical care be familiar with these concepts.
