The ethical validity and clinical experience of palliative sedation.

The physician's main goal in caring for a dying person is to reduce suffering, including pain, physical symptoms, and emotional, psychosocial, and spiritual distress. In refractory and intractable cases, palliative sedation offers a compassionate and humane alternative to conscious and continual suffering, both for the patient and the patient's family. Without a doubt, further studies are necessary, particularly in cases of cognitive impairment, but palliative sedation offers a valuable and efficacious intervention for interminable suffering at the end of life.
