[Legal aspects of transplant and donation].

The Spanish model of organ and tissue donation enjoys great prestige in the world medical sphere and has been the object of study and imitation in different countries. Part of this success is due to the fact that since the year 1979 different legal norms have been enacted that have regulated and facilitated donation. The current legislation on the donation and transplant of organs and tissues is based on the principles of the gratuity and confidentiality of the donation, indicating the need for facilitating the formation of organisations at the level of the autonomous communities and at the national level. It also contains the requisites for donation of both live donors and deceased donors, establishing the norms for certification of death due to cardiorespiratory arrest and due to the irreversible cease of brain functions.
