Dexmedetomidine: A Novel Strategy for Patients with Intractable Pain, Opioid-Induced Hyperalgesia, or Delirium at the End of Life.

Hofherr ML, Abrahm JL, Rickerson E. J Palliat Med; ahead of print. Accessed online on February 15, 2020. DOI: 10.1089/jpm.2019.0427.

In 2002, Soares et al1 reported the use of dexmedetomidine for the treatment of intractable distress in the dying. Later, it was reported that dexmedetomidine was used to facilitate the withdrawal of ventilatory support in palliative care2, as well as for delirium, intractable pain3, and patients with opioid-induced hyperalgesia4.

A new report by Hofherr et al describe eight patients suffering from intractable pain, delirium, or agitation treated with a continuous infusion of 0.1-1.5 mcg/(kg/h) and an optional IV bolus of 0.4-1 mcg/kg for 10 to 30 minutes. The symptoms of these eight patients were improved; distress was reduced and in three cases the opioid dosage was also reduced without withdrawal symptoms.

Dexmedetomidine is an α2-adrenergic agonist with sedative and analgesic properties approved for use in the United States since 1999.

As the authors conclude, more studies are needed in order to explore the use of this medication, which could play an important role in the treatment of patients with severe health-related suffering.

Dexmedetomidine, a selective alpha2agonist, is traditionally used briefly for perioperative anesthesia and sedation of mechanically ventilated patients. Reports of its use in patients with opioid-induced hyperalgesia and intractable pain and delirium suggested it for patients who otherwise may have required palliative sedation to relieve suffering. We present the protocol developed by the interdisciplinary team in our intensive palliative care unit that allows for safe titrated administration without required vital sign monitoring outside the intensive care unit (ICU) (Supplementary Appendix SA1). We describe its efficacy in eight patients who were receiving comfort-focused care.

Media Watch: Updates

New articles on three MediaWatch topics previously covered by Barry R. Ashpole: family caregivers, GPs, and long-term care.

Family Caregivers

Development and Implementation of the Family Caregiver Decision Guide

Quality Health Research, 2020; 30(2): 303-313. The Guide was designed to address the pressing need for interventions to support family members caring for seriously ill people at home. Family was conceptualized as whoever the ill person accepts as family. The Guide focuses on supporting decision making in planning care for their family member. DOI: 10.1177/1049732319887166.

Home Care and End-of-Life Hospital Admissions: A retrospective interview study in English primary and secondary care

British Journal of General Practice, 2019; 69(685): e561-e569. If policy and practice maintain an emphasis on facilitating deaths at home there must be a concurrent focus on ensuring patients can die there safely. Identifying how best to achieve this will require further research and investment to ensure community nursing provision is adequately staffed, responsive and available 24/7.

Australian GPs’ Perceptions of Barriers and Enablers to Best Practice Palliative Care: A qualitative study

BMC Palliative Care | Online – 31 October 2019 – GPs reported difficulties with the provision of palliative care due to: 1) The complex, often emotional nature of doctor-family-interaction; 2) A lack of evidence to guide care; and, 3) The need to negotiate roles and responsibilities. GPs listed strategies to address their workload and improve communication between healthcare providers. DOI: 10.1186/s12904-019-0478-6.
