Palliative sedation is used as a last-resort option to treat refractory symptoms of dying patients. Nurses are important participants in the process of sedation. However, little is known about palliative sedation from a nursing perspective.

To analyze the practices and attitudes of nurses concerning palliative sedation. A scoping review guided by Arksey and O`Malley`s methodological framework was used to analyze existing peer-reviewed empirical research on the topic of the practices and attitudes of nurses related to the palliative sedation of patients aged 18 years and older. Of the 316 publications identified from the PubMed, CINAHL and Cochrane Library, 17 full-text articles were included in this review. The data of the included articles were charted (author(s), year of publication, country, objectives, study design, data collection, setting, respondents, definition of palliative sedation, focus of the study and key findings), and the results were summarized with inductive content analysis. The PRISMA-ScR checklist was used as a guideline for the reporting in this review.

During the decision-making concerning the start of palliative sedation, nurses usually have an advocatory and supportive role, although the role varies between different countries. This role then changes to a relatively independent performance of sedation; including administration of the medication, monitoring the effectiveness of sedation, and in some cases taking decisions concerning the medication and dosage policy. Further, nurses provide information and compassionate care to both the patient and the family during the process of palliative sedation. Most nurses view palliative sedation as a positive and sometimes necessary last resort therapy to relieve refractory suffering of dying patients. However, sedation poses ethical problems for many nurses. These problems especially concern the essential elements of deciding to use palliative sedation, the depth of sedation, the potential for shortening life, and the loss of social interaction.
Nurses play a key role in palliative sedation, as they often perform sedation independently and have important information about the needs and wishes of both patients and their families due to their unique position at the bedside of the patient. Although nurses generally see palliative sedation as a positive practice for selected patients, many of them feel it is ethically controversial. This scoping review reveals a great need for further research and discussion on the practices and attitudes of nurses regarding palliative sedation.
