RESUMEN
BACKGROUND AND OBJECTIVE: The indication "existential suffering (ES)" for palliative sedation therapy is included in most frameworks for palliative sedation and has been controversially discussed for decades. The appellative character of ES demands rapid relief and sedation often appears to be the best or only solution. ES is still poorly understood and so often neglected by health care professionals due to a lack of consensus regarding assessment, definition and treatment in the international medical literature. Based on a selective review of the literature on ES we propose a different view on the underlying processes of ES and the resulting consequences on medical treatment. METHODS: A narrative review was performed after PubMed search using key terms related to ES and sedation, covering the period from 1950 to April 2023, additionally a selective search in specialist literature on Existential Analysis. Reverse and forward snowballing followed. The language of analyzed publications was restricted to English and German. KEY CONTENT AND FINDINGS: ES is a multidimensional experience that tends to turn into despair and ultimately into a wish to die due to perceived hopelessness and meaninglessness. Pharmacological treatment or sedation do not meet the holistic needs of existential sufferers. The risk of harmful effects by continuous deep sedation seems to be significantly increased for existentially suffering patients. Professional caregivers are burdened by the appellative character of ES, limited treatment options and perceived empathic distress. Without a holistic understanding of the human condition in palliative care, ES cannot be fundamentally alleviated, and existential sufferers have no opportunity to transform and thus mitigate their condition. The recognition of underlying causes of suffering-moods is facilitated by the comprehensive approach of Existential Analysis. CONCLUSIONS: The presented concept of Existential Analysis and the triad of ES are useful instruments for health care professionals to recognize and support underlying moods of existentially suffering patients. Further studies are required. Comprehensive training for professional caregivers on ES is essential to enable them to reflect on their own existential concerns and finiteness as well as those of patients. Continuous deep sedation for ES must remain the exception, equivalent to a last resort option.
