Abstract：
UNASSIGNED: Though palliative sedation has been recognized as an acceptable practice in Canada for many years now, there is a lack of clinical research and guidelines pertaining to its use as a treatment of existential refractory symptoms in the terminally ill.
UNASSIGNED: This scoping review aimed to survey the literature surrounding palliative sedation and existential suffering and to inform research, policy, and practice.
UNASSIGNED: To address the main research question: Is palliative sedation an acceptable intervention to treat existential refractory symptoms in adults aged 65 and older? a scoping review following Arksey and O\'Malley\'s framework was performed, spanning electronic databases of the peer reviewed and grey literature. Articles were screened for inclusion, and a thematic content analysis allowed for a summary of key findings.
UNASSIGNED: Out of 427 search results, 71 full text articles were obtained, 20 of which were included. Out of these articles, four themes were identified as key findings. These included: (1) Ethical considerations; (2) The role of the health care provider; looking specifically at the impact on nurses; (3) The need for multidisciplinary care teams; and (4) Existential suffering\'s connection to religiosity and spirituality.
UNASSIGNED: Palliative sedation to treat existential refractory symptoms was labelled a controversial practice. A shortage of evidence-based resources limits the current literature\'s ability to inform policy and clinical practice. There is a need for both qualitative and quantitative multi-center research so health care professionals and regional-level institutions have firm roots to establish proper policy and practice.

摘要：
虽然姑息镇静在加拿大已经被认为是一种可接受的做法多年了，缺乏关于将其用作治疗绝症患者中存在的难治性症状的临床研究和指南。
■本范围审查旨在调查有关姑息镇静和生存痛苦的文献，并为研究提供信息，政策,和实践。
■为了解决主要的研究问题：姑息性镇静是治疗65岁及以上成人的存在难治性症状的可接受的干预措施吗？根据Arksey和O\'Malley的框架进行了范围审查，跨越同行评审的电子数据库和灰色文献。对文章进行了筛选，主题内容分析允许总结关键发现。
■在427个搜索结果中，共获得71篇全文，其中包括20个。在这些文章中，四个主题被确定为关键发现.其中包括：（1）道德考虑；（2）医疗保健提供者的作用；特别是对护士的影响；（3）需要多学科护理团队；（4）存在的痛苦与宗教和灵性的联系。
■治疗存在的难治性症状的姑息镇静被标记为有争议的做法。缺乏基于证据的资源限制了当前文献为政策和临床实践提供信息的能力。需要定性和定量的多中心研究，以便医疗保健专业人员和区域一级的机构有坚实的基础来建立适当的政策和实践。
