Introduction

Ethical issues:

  • there is no right answer
  • ethically & legally there is no difference between witholding & withdrawing treatment
  • some patients or families believe that hydration must always be provided even if it causes discomfort, usually based on personal or religious beliefs
  • little benefit in the dying patient & may cause unwanted symptoms

Adverse effects

Laboratory

Notes

Palliative effects of dehydration:*

* Dry mouth is the most frequent complication of dehydration in the dying patient. Sips of water, ice chips & lubricants can alleviate this symptom. Hunger & thirst are rarely a problem.

Prognosis (in absence of hydration):

  • death will generally occur within days of ceasing intake
  • often the patient survives much longer than expected
  • terminally ill patients not given artificial hydration may actually survive longer than those that are hydrated
