euthanization在生物学中是什么意思

如题所述

　　安乐死

　　中文解释：
　　安乐死指对无法救治的病人停止治疗或使用药物，让病人无痛苦地死去。 “安乐死”一词源于希腊文，意思是"幸福"的死亡。它包括两层含义，一是安乐的无痛苦死亡；二是无痛致死术；我国的定义指患不治之症的病人在垂危状态下，由于精神和躯体的极端痛苦，在病人和其亲友的要求下，经医生认可，用人道方法使病人在无痛苦状态中结束生命过程。

　　英文解释：

　　1. an easy or painless death.
　　2. the deliberate ending of life of a person suffering from an incurable disease. In recent years the concept has been broadened to include the practice of withholding extraordinary means or “heroic measures,” and thus allowing the patient to die (see extraordinary treatment). A distinction was traditionally made between positive or active euthanasia, in which there is the deliberate ending of life and an action is taken to cause death in a person, and negative or passive euthanasia, which is the withholding of life-preserving procedures and treatments that would prolong the life of one who is incurably and terminally ill and could not survive without them. However, now all euthanasia is generally understood to be active, and so the more accurate term forgoing life-sustaining treatment is replacing passive euthanasia. See also advance directives.
