Medical assistance in dying (MAiD) and palliative sedation (PS) are both legal options in Canada that may be considered by patients experiencing intolerable and unmanageable suffering. A contentious, lively debate has been ongoing in the literature regarding the similarities and differences between MAiD and PS. The aim of this paper is to explore the propositions that MAiD and PS are essentially similar and conversely that MAiD and PS are distinctly different. The relevance of such a debate is apparent for clinicians (...) and patients alike. Understanding the complex and multi‐faceted nuances between PS and MAiD allows patients and caregivers to make more informed decisions pertaining to end‐of‐life care. It is hoped that this paper will also serve to foster further debate and consideration of the issues associated with PS and MAiD with a view to improve patient care and the quality of both living and dying in Canada.

In assisted dying, the end-of-life trajectory is shortened to relieve unbearable suffering. Unbearable suffering is defined broadly enough to include cognitive (early dementia), psychosocial or existential distress. It can include old-age afflictions that are neither life-threatening nor fatal in the “vulnerable elderly”. The voluntary refusal of food and fluids (VRFF) combined with continuous deep sedation (CDS) for assisted dying is legal. Scientific understanding of awareness of internal and external nociceptive stimuli under CDS is rudimentary. CDS may blunt the wakefulness component (...) of human consciousness without eradicating internal affective awareness of thirst and hunger. Patients may suffer because of the slow dying process following dehydration and starvation. The difficulty to adequately control distress, without bringing the dying process to a rapid conclusion by lethal pharmacological interventions, can cause feelings of guilt among hospice and medical staff. Furthermore, the double-effect principle is not applicable in these situations because the primary objective of VRFF is to hasten death. Legal and societal debate should focus on sharpening the boundaries between assisted dying and palliative care. This separation is necessary to: 1) uphold trust in the patient-phyician relationship, and 2) preserve integrity and ethics of the medical profession. (shrink)

Patients who are imminently dying sometimes experience symptoms refractory to traditional palliative interventions, and in rare cases, continuous sedation is offered. Samuel H. LiPuma, in a recent article in this Journal, argues that continuous sedation until death is equivalent to physician-assisted suicide/euthanasia based on a higher brain neocortical definition of death. We contest his position that continuous sedation involves killing and offer four objections to the equivalency thesis. First, sedation practices are proportional in a way that physician-assisted suicide/euthanasia is not. (...) Second, continuous sedation may not entirely abolish consciousness. Third, LiPuma’s particular version of higher brain neocortical death relies on an implausibly weak construal of irreversibility—a position that is especially problematic in the case of continuous sedation. Finally, we explain why continuous sedation until death is not functionally equivalent to neocortical death and, hence, physician-assisted suicide/euthanasia. Concluding remarks review the differences between these two end-of-life practices. (shrink)
