BACKGROUND: The appropriate provision of sedation as a last resort for the relief of suffering in palliative care is dealt with variably in actual practice. This article is intended as an overview of practically relevant information found in treatment recommendations and guidelines. METHODS: A systematic literature search was conducted in the PubMed, Scopus, and Google Scholar databases, and a manual search was carried out online. Recommendations that were not available in either German or English, or that were specific to pediatric practice, were excluded. Publication quality was assessed with the AGREE II instrument (Appraisal of Guidelines for Research & Evaluation II). The recommendations in the documents were qualitatively evaluated. RESULTS: 29 publications (11 journal articles, 18 other) of varying quality according to AGREE II were included. All recommendations and guidelines were essentially based on expert consensus. The common indications for sedation are otherwise intractable delirium, dyspnea, and pain, in patients with a life expectancy of no more than two weeks. Existential distress is a controversial indication. The drug of first choice is midazolam. As the sedating effect of opioids is hard to predict, they should not be used as sedatives. The risks of sedation include respiratory and circulatory depression, as well as the loss of communicative ability, control, and autonomy. It is generally recommended that the patient's symptom burden and depth of sedation should be monitored; clinical and technically supported monitoring are recommended in some publications as well, depending on the situation. CONCLUSION: There is a broad consensus in favor of sedation to relieve suffering in the last days and hours of life. Recommendations vary for patients with a longer life expectancy and for those with existential distress, and with respect to monitoring.
