Zorluk: OrtaEnd-of-Life and Palliative Care

A 68-year-old man with progressive amyotrophic lateral sclerosis is brought to the emergency department by emergency medical services due to worsening shortness of breath and lethargy over the past 24 hours. On arrival, he is obtunded and responsive only to painful stimuli. Vital signs show a heart rate of 110/min, blood pressure of 145/90 mm Hg, and respiratory rate of 28/min. Oxygen saturation is 82% on room air, and arterial blood gas analysis reveals a pH of 7.18 and a PaCO2 of 85 mm Hg. The patient lacks decision-making capacity. His wife, who is his legally designated healthcare proxy, is present. The electronic medical record contains a valid advance directive completed by the patient three months ago when he had full capacity. The document explicitly states he does not want endotracheal intubation or invasive mechanical ventilation under any circumstances, but he wishes to receive non-invasive positive pressure ventilation for symptom relief. The wife is tearful and states, "I know what the form says, but he was depressed when he signed it. I cannot lose him today. You must intubate him."

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

  1. Initiate non-invasive positive pressure ventilation and decline the request for intubationCevap
  2. B
    Proceed with endotracheal intubation as directed by the legally designated healthcare proxy
  3. C
    Require a court order to determine the patient's legal competence at the time the directive was signed
  4. D
    Withhold all interventions and urgently consult the hospital ethics committee to resolve the conflict
  5. E
    Administer high-dose intravenous lorazepam to alleviate respiratory distress while preparing for intubation

Cevap

Initiate non-invasive positive pressure ventilation and decline the request for intubation
The most appropriate action is to honor the patient's explicitly documented wishes. When a patient loses decision-making capacity, an advance directive serves as their voice. Because the directive clearly addresses the current clinical scenario (refusing intubation but accepting non-invasive ventilation), the physician is ethically and legally obligated to follow it, even if the legally designated healthcare proxy disagrees. The proxy's role is to facilitate the patient's wishes, not to substitute their own preferences.

Adım Adım Çözüm

1
Assess the patient's clinical status and capacity.
The patient is in acute hypercapnic respiratory failure, is obtunded, and lacks decision-making capacity.
Determining capacity is the first step in deciding who directs medical care.
2
Review available advance directives and identify the surrogate decision-maker.
A valid advance directive explicitly refuses intubation but accepts non-invasive positive pressure ventilation. The wife is the healthcare proxy.
When a patient lacks capacity, prior documented wishes guide care. The surrogate's role is to enforce those wishes, not override them.
3
Address the conflict between the surrogate's request and the advance directive.
The physician must honor the clear, applicable advance directive over the wife's emotional request for intubation.
A surrogate decision-maker must follow the principle of substituted judgment, meaning they must make the decision the patient would make. A clear advance directive represents the patient's voice.

Anahtar Kavram

An explicit, valid advance directive supersedes the conflicting wishes of a surrogate decision-maker or healthcare proxy.
