Sedation for the relief of refractory symptoms in the imminently dying: a fine intentional line.
There is a continuum of the goals of comfort and function in palliative care that begins with comfort and function being equal priorities and sedation being unacceptable. As disease progresses, the goals and preferences of the patient turn to coping with the loss of function caused by the disease and acceptance of unintentional sedation from the disease, its therapies, or symptom relief interventions. As patients approach the end of life, they may need intentional sedation for the relief of refractory symptoms. Such sedation can be divided into three categories: routine, infrequent, and extraordinary with respect to the frequency, difficulty, and risks involved with the drugs and routes of administration required to induce and maintain a level of sedation that relieves the patient's physical and existential symptoms. Extraordinary sedation with continuous infusions of midazolam, thiopental, and propofol can relieve refractory symptoms in most patients in their final days of life. Palliative care clinicians should become comfortable with the ethical justification and technical expertise needed to provide this essential, extraordinary care to the small but deserving number of patients in whom routine and infrequent sedation does not adequately relieve their suffering.
