Palliative sedation at end of life - a systematic literature review.

Palliative sedation at the end of life to handle unmanageable symptoms has been much debated. A systematic literature review in three phases including a content analysis of 15 articles published between the years 1990 and 2005 has been conducted. The aim was to describe the phenomenon of 'palliative sedation at the end of life' from a nursing perspective. The results can be summarised in three themes: 'Important factors leading to the patient receiving sedation at the end of life', 'Attitudes to palliative sedation at the end of life' and 'Nurses' experience of palliative sedation at the end of a patient's life'. Together, the themes show that palliative sedation is a phenomenon that could be described as sedation given to fewer than 40% of dying patients during their last 4 days of life. It is usually given because of the patient's pain, agitation and/or dyspnoea. Professionals usually have positive attitudes towards it and their view differs from that of the public's view regarding it as continuously deep sedation, whereas the public regards it as being close to euthanasia. Studies focusing on nursing care during palliative sedation are hard to find and this underlines the importance of further research in this area to elucidate the nurses' role during palliative sedation.
