The authors give a short overview about the background of the organisation of the liver transplantation and about the process of the "liver alarm". One of the most important work of the coordinator is to increase the number of organ donation. The other part of the preparation of liver transplantation is to create the recipient waiting list. The organisation of the "liver alarm" needs the work of two coordinators. The donor coordinator keeps contact with the donor hospital, harmonizes the travel of different transplant teams and organizes the organ explantation. In the same time, the recipient coordinator prepares the liver recipient for the liver transplantation and keeps contact with the donor coordinator in the donor hospital. If the donor liver macroscopically seems good for transplantation, the patient can be send to the operating room and the work of the anaesthesiologists and the surgeons starts.
