Parenteral nutrition complications in palliative medicine.

Parenteral nutrition in palliative care is contentious, and decisions on starting or continuing its treatment in palliative patients centre on an individual's preference, balanced with quality of life. This case report describes the unusual onset of pain and agitation secondary to fluid retention, in a patient with metastatic pseudomyxoma peritonei, established on 2.5 L/day of parenteral nutrition. Immediate volume reduction of the parenteral nutrition to 1 L/day successfully reversed the patient's symptoms. To our knowledge, this is the first case of parenteral nutrition inducing pain and agitation in a palliative care patient. There is no specific internationally acclaimed guidance concerning parenteral nutrition content and volume in palliative patients, due to a lack of high quality studies. This case study highlights the need for further research into parenteral nutrition content and volume in palliative care, to prevent harmful effects from fluid retention, impacting on quality of life.
