Zorluk: Çok zorAdvance Directives and End-of-Life Care

An 82-year-old woman with advanced Alzheimer disease is admitted to the medical intensive care unit with severe aspiration pneumonia and septic shock. She is obtunded, unresponsive to verbal stimuli, and definitively lacks decision-making capacity. Her prognosis is grave, with death anticipated within hours. The patient has a legally executed advance directive specifying her wish for 'comfort measures only' at the end of life and explicitly designating her eldest son as her sole healthcare proxy.

The patient exhibits severe tachypnea and accessory muscle use, indicating significant air hunger. After discussing the prognosis with the attending physician, the eldest son requests the initiation of an intravenous morphine infusion to relieve his mother's respiratory distress. He acknowledges understanding that this intervention may depress her respiratory drive and hasten her death. Shortly after this discussion, the patient's younger daughter, who is a practicing intensive care unit nurse, arrives at the bedside. She vehemently objects to the morphine, arguing that it will cause fatal respiratory depression. She threatens to file a complaint with the state medical board if the opioid is administered and demands an immediate emergency ethics committee consultation to halt the infusion.

Which of the following is the most appropriate next step in management?

  1. Initiate the intravenous morphine infusion as requested by the eldest son.Cevap
  2. B
    Withhold the morphine infusion temporarily and convene an emergency ethics committee meeting.
  3. C
    Administer a continuous infusion of midazolam instead of morphine to treat the air hunger.
  4. D
    Defer decision-making to the daughter because of her clinical expertise in intensive care.
  5. E
    Seek an expedited court order to confirm the eldest son's authority as the sole proxy.

Cevap

Initiate the intravenous morphine infusion as requested by the eldest son.
The eldest son is the legally designated healthcare proxy, which grants him the exclusive legal authority to make medical decisions on the patient's behalf since she lacks capacity. His request for morphine to treat air hunger is medically appropriate and aligns with the patient's directive for 'comfort measures only'. The administration of medication with the primary intent to relieve suffering, even if it has the foreseeable but unintended consequence of hastening death, is ethically permissible and legally protected under the principle of double effect. The daughter's medical background does not grant her surrogate authority, and delaying palliative care to consult an ethics committee in the presence of a clear, legally appointed proxy would cause the patient unnecessary suffering.

Adım Adım Çözüm

1
Assess the patient's decision-making capacity.
The patient is obtunded and definitively lacks capacity.
To determine if a surrogate decision-maker is required.
2
Identify the legally authorized surrogate decision-maker.
The eldest son is the legally designated healthcare proxy via the advance directive.
To ensure medical decisions are made by the individual with the legal authority to do so.
3
Evaluate the proxy's request for morphine.
The request is medically appropriate for treating terminal air hunger and aligns with the principle of double effect.
To ensure the surrogate's decision does not violate standard medical ethics.
4
Address the younger daughter's objection.
