[Ethical discussion of palliative sedation].

This article discusses ethical implications of palliative sedation at the end of life. Terminal or palliative sedation, like other denominations are discussed in literature, which invite to a profound discussion. From an ethical point of view, terminal or palliative sedation seems to be a way out when in intolerable suffering or situations without prospects, the demand for euthanasia arises. The possibility to use palliative sedation for effective control of otherwise refractory suffering provokes the question if it even can be used with the intention to hasten death. This has led to ethical concerns on the use and limits of sedation. Therefore it seems to be necessary to elaborate clear guidelines in handling sedation in end-of-life care to prevent misuse. The contribution of ethical considerations can clarify the position and use of palliative sedation.
