Palliative Sedation for Existential Suffering: A Systematic Review of Argument-Based Literature

Rodrigues P., Crokaert J. & Gasmans C. (2018), in Journal of Pain and Symptom Management, 55/6, pp. 1577-1590.
Although unanimity exists on using palliative sedation (PS) for controlling refractory physical suffering in end-of-life situations, using it for controlling refractory existential suffering (PS-ES) is controversial. Complicating the debate is that definitions and terminology for existential suffering are unclear, ambiguous, and imprecise, leading to a lack of consensus for clinical practice.
