Purpose Of Review: Palliative sedation has been the subject of intensive debate since its first appearance in 1990. In a 2010 review of palliative sedation, the following areas were identified as lacking in consensus: inconsistent terminology, its use in nonphysical suffering, the ongoing experience of distress, and concern that the practice of palliative sedation may hasten death. This review looks at the literature over the past 6 years and provides an update on these outstanding concerns.
Recent Findings: Good clinical guidelines and policies are still required to address issues of emotional distress and waylay concerns that palliative sedation hastens death.
Summary: The empirical evidence suggests some movement toward consensus on the practice of palliative sedation. However, a continued need exists for evidence-informed practice guidelines, education, and research to support the ethical practice of palliative sedation at the end of life. Until that time, clinicians are advised to adopt a framework or guideline that has been expert driven to ensure consistent and ethical use of palliative sedation at the end of life.

Interventional endoscopy procedures are challenging for anaesthesiologists due to the various patient, procedural, logistic, and position-related issues. Complex endoscopic procedures like biliary interventions and endoscopic myotomy necessitate longer procedural duration. The mode of anaesthesia is usually deep sedation without any definitive airway device and is frequently associated with hypoxemia events which can be catastrophic.

Palliative sedation is intended to be an end of life option that enables healthcare professionals to provide good patient care but there remains controversy on how it is used. Little is known about decision-making processes regarding this procedure.
