Propofol for terminal sedation in palliative care: a systematic review

We undertook a systematic review of published evidence of the effectiveness of propofol for terminal sedation. INCLUSIONS: Prospective or retrospective trials (controlled or uncontrolled) or case series of propofol for sedation in advanced incurable disease in either generalist setting or specialist palliative care units. Use in anesthetic or intensivist settings (e.g., intensive care units); pediatric use. Identification of relevant studies: Using the search terms: [Hospice Care/OR Terminal Care/OR Palliative Care/OR palliative.mp] AND [Propofol/]. Studies were identified using a detailed search strategy from a number of electronic databases: Embase (1988-2005); MEDLINE (1966-2005) Cinahl (1982-2005), Cancerlit (1962-2005) The Cochrane Database of Systematic Reviews 2005 Issue 4. Hand searches of a number of palliative care journals were also undertaken (Palliative Medicine, Journal of Pain and Symptom Management, Progress in Palliative Care, Journal of Palliative Care, Journal of Palliative Medicine). No restriction was placed on the language of the original article. Four articles--all case series or case reports--reporting generally favorable reports of the use of propofol as sedation for intractable symptoms in the last days of life especially when one or more other drugs have failed. Since these four articles are essentially hypothesis-generating, the article also discusses the possibility of the design of a clinical trial to compare propofol with other drugs used in this situation.
