[Brain Death and Treatment of (Potential) Organ Donors and Interactions with their Relatives].

In recent years, the diagnosis of irreversible brain function loss in severely brain-damaged patients has gained in importance. Brain death, defined as an irreversible loss of the overall function of the cerebrum, cerebellum and brain stem, is a prerequisite for organ removal in the context of organ donation. The article presents the legal and organizational framework.Brain death is determined on the basis of the latest update of the guidelines of the German Medical Chamber (Bundesärztekammer) using a three-step scheme and consists of clinical and instrumental examinations. After the final diagnosis of brain death, the phase of organ-preserving treatment for the potential organ donor begins. In the case of patients who themselves or their relatives have not agreed to organ donation, the intensive care therapy must be terminated promptly. The legal framework for the determination of brain death and for the removal of organs from potential organ donors is provided by the Transplantation Act. The German Foundation for Organ Transplantation (DSO) is responsible for the coordination of organ donations in Germany. The DSO supports hospitals in many ways during the organ donation process, but also in training courses for medical staff on organ donation. The main contact person of the DSO is the transplant officer in the hospitals. The care of the relatives of a potential organ donor is of great importance.
