Withdrawing life-sustaining treatment from severely brain-damaged persons

Area of Science:

• Medical Ethics
• Neurology
• Critical Care Medicine

Background:

• Ventilator support withdrawal is standard for unconscious, non-breathing patients when treatment is futile.
• Permanently unconscious patients who can breathe but not swallow present a consistent practice challenge.
• Ongoing treatment for these patients is also considered futile, yet withdrawal of artificial nutrition and hydration lacks clear guidelines.

Purpose of the Study:

• To review the medical, legal, and ethical literature regarding the withdrawal of tube feeding in patients with severe brain damage.
• To identify and propose consistent criteria for the withdrawal of life-sustaining treatment in permanently unconscious patients.

Main Methods:

• Literature review of medical, legal, and ethical discussions on withdrawing artificial nutrition and hydration.
• Analysis of existing practices and ethical considerations for end-of-life care in severe brain injury.

Main Results:

• Significant disagreement exists in the literature regarding the criteria and procedures for withdrawing tube feeding.
• Withdrawal of treatment, including artificial nutrition and hydration, is not euthanasia; death results from the underlying illness.

Conclusions:

• Proposed criteria for withdrawing treatment include permanent unconsciousness, permanent loss of life-sustaining function, sufficient time for prognosis certainty, independent medical specialist concurrence, and informed consent from family or legal agents.
• Establishing consistent guidelines is crucial for ethical and consistent end-of-life care for patients with severe brain damage.
