器官捐献作为器官移植中的核心环节，其如何分配常常引发伦理学的争议。我国的器官捐献原则中所包含的器官捐献者直系亲属优先原则是极具伦理价值及社会效益的，将“器官捐献者及其直系亲属的优先权”表述为“家庭优先原则”更符合中国国情。从生命伦理学“有利、尊重自主、不作恶、公正”四原则出发，为我国的家庭优先原则辩护，以提升民众对我国捐献器官分配体系的信任度，促进我国器官移植工作进一步开展。

Organ donation is recognized as the core part of organ transplantation and its distribution often raises ethical controversy. Organ donor’s lineal consanguinity priority included in Chinese organ donation principles has extreme ethical values and social benefits. Stating "organ donors and their lineal consanguinity priority" as "family priority principle" is much more accorded with China’s national conditions. Beginning with the four principles of "benefit, respect and autonomy, no harm, and justice", this paper defended family priority principle in our country, in order to enhance public trust in organ donation distribution system of our country and promote the further development of organ transplantation.
