Zorluk: Çok zorEnd-of-Life and Palliative Care

A 58-year-old woman is admitted to the hospital with intractable vomiting and severe, diffuse abdominal pain. She has stage IV ovarian cancer with extensive peritoneal carcinomatosis. Laboratory studies are significant for a serum creatinine of 3.8 mg/dL (baseline 0.9 mg/dL). On examination, the patient is lethargic, oriented only to her name, and unable to participate in medical decision-making.

A legally binding living will, signed by the patient one year ago, is present in her electronic medical record. The document explicitly refuses artificial nutrition, hydration, and surgical interventions in the event of an incurable, terminal condition, requesting only symptom-directed comfort care. She did not formally designate a healthcare power of attorney.

The patient is accompanied by her adult son, who has been her sole caregiver. Shortly after admission, the patient's legal husband arrives. The patient and her husband have been informally separated for four years, with no legal separation or divorce filed. The husband demands that the medical team place a percutaneous feeding tube and perform a palliative venting gastrostomy. He states, "I am still her legal husband and highest-ranking decision-maker. I am officially revoking her living will right now." The son strongly objects, demanding the team follow the living will and administer intravenous morphine for her severe pain.

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

  1. Decline the husband's requests, as the living will remains in effect, and administer intravenous fentanyl for symptom control.Cevap
  2. B
    Decline the husband's requests based on the son's objection and administer intravenous morphine for symptom control.
  3. C
    Honor the husband's revocation of the advance directive, as he is the highest-ranking legal surrogate, and consult general surgery.
  4. D
    Consult psychiatry to determine the patient's legal competence before allowing any family member to make decisions contrary to the living will.
  5. E
    Withhold opioid analgesics to prevent worsening encephalopathy in the setting of acute kidney injury and consult the hospital ethics committee.

Cevap

The medical team must honor the living will, declining the husband's demands, and treat the patient's pain using intravenous fentanyl.
The correct action synthesizes both ethical and pharmacologic principles. Ethically, a valid living will represents the patient's direct voice and cannot be revoked or overridden by any surrogate (including a spouse) when the patient lacks capacity. The medical team is legally and ethically bound to honor the document and decline the feeding tube and surgery. Pharmacologically, the patient requires immediate pain management, but her acute kidney injury (creatinine 3.8 mg/dL) makes morphine unsafe due to the accumulation of toxic metabolites. Fentanyl is hepatically cleared and lacks active renally cleared metabolites, making it the safest opioid choice in this scenario.

Adım Adım Çözüm

1
Assess the patient's clinical capacity and the applicability of the advance directive.
The patient lacks capacity (lethargic, oriented to name only) and has a valid, applicable living will that refuses feeding tubes and surgery in her current terminal state.
Establishing capacity determines whether the patient can make her own decisions or if an advance directive/surrogate must be utilized.
2
Evaluate the husband's claim to revoke the living will.
The claim is rejected. A surrogate cannot revoke a patient's valid advance directive.
The living will is the direct expression of the patient's autonomy. Surrogates are meant to enact the patient's known wishes (substituted judgment), not override them.
3
Select the appropriate pharmacologic intervention for severe pain in the setting of acute kidney injury (Cr 3.8 mg/dL).
Fentanyl (or methadone) is selected instead of morphine.
Morphine is metabolized into active, renally cleared metabolites that rapidly accumulate in acute kidney injury, leading to severe neurotoxicity and respiratory depression.

Anahtar Kavram

Surrogate decision-makers cannot revoke a valid living will when a patient lacks capacity; additionally, fentanyl is preferred over morphine in severe renal failure.
