Rehydration in palliative and terminal care: if not--why not?

Area of Science:

• Palliative Care
• End-of-Life Care
• Medical Ethics

Background:

• Dying patients often cannot take oral fluids/nutrition due to disease or sedation.
• Intravenous (i.v.) fluid rehydration is common in acute care but debated in hospice.
• Complex physical, psychological, social, and ethical issues surround fluid management in terminal illness.

Purpose of the Study:

• To review the literature on the benefits and burdens of i.v. fluids in dying patients.
• To explore the symptomatic relief, ethical dilemmas, and communication aspects of i.v. fluid use.
• To discuss alternative fluid replacement methods and decision-making in terminal care.

Main Methods:

• Literature review on i.v. fluids and dehydration in end-of-life care.
• Analysis of conflicting reports on physical discomfort and confounding variables.
• Discussion of ethical considerations, patient-centered care, and futility of treatment.

Main Results:

• Evidence is conflicting regarding symptomatic relief from dehydration in dying patients.
• Confounding variables like medications and mouth breathing complicate assessments.
• i.v. fluids may present a barrier to family connection and send confusing messages about medical intervention.

Conclusions:

• The balance of burdens and benefits of i.v. fluids in terminal care is subjective and unproven.
• Patient comfort should be the primary goal, with decisions individualized and involving patients/carers.
• Prolonging life is secondary; i.v. fluids may be futile and ethically complex in this context.
