[Palliative Sedation: Comments on a controversial topic]

Palliative Sedation: Comments on a controversial topic Abstract. Palliative sedation (PS) is an accepted medical practice for terminally ill patients. It intends the alleviation of unbearable suffering by intentionally lowering the level of consciousness. In contrast to physician assisted suicide and euthanasia, palliative sedation aims to relieve burdensome symptoms with no intention of hastening death. PC can be applied as "intermittent palliative sedation" or "continuous (deep) sedation until death". Most ethical controversies are related to the latter form of PS: 1: Is existential or psychosocial suffering a possible indication for PS? 2: What is the earliest possible time point to start PS? 3: The withdrawal or withholding of artificial nutrition and hydration during PS. A critical reflection of these ethical controversial aspects within the treatment team is highly desirable. However, the patient's well-being and the respect for the patient's decisions that are based on experiences which are made only by him or her, must remain the guiding principle for medical actions.
