Symptom management at end of life

Pain Management - The Final Comfort

• Goal: Patient comfort, not prolonging life or hastening death. Use a multimodal approach.
• Assessment: Use a validated pain scale (e.g., Numeric Rating Scale 0-10).
• Opioid Therapy: The cornerstone of severe pain management.
  • Morphine is the gold-standard first-line agent.
  • Start with short-acting opioids (e.g., oral morphine 5-15 mg q4h PRN).
  • Convert to long-acting formulations (e.g., MS Contin, Fentanyl patch) once pain is stable.
  • Titration: Increase dose by 25-50% for persistent pain. No ceiling dose.

⭐ Principle of Double Effect: It is ethically permissible to administer potentially life-shortening medication (e.g., high-dose opioids) to relieve suffering, provided the primary intention is symptom relief, not causing death.

Respiratory Relief - Breath & Peace

• Primary Goal: Alleviate the subjective sensation of dyspnea, not solely to correct underlying hypoxia.

• Initial Management: First, identify and treat reversible causes (e.g., fluid overload, pneumonia, bronchospasm, PE).

• Pharmacologic Therapy:

  • Opioids: First-line treatment for refractory dyspnea.
    • Start low-dose Morphine (2.5-5 mg PO q4h PRN).
    • Titrate dose based on symptom relief.
  • Anxiolytics: Benzodiazepines (e.g., lorazepam) can be added to manage anxiety associated with breathlessness.

⭐ Opioids are the standard of care for end-of-life dyspnea, regardless of pain presence. Their primary effect is central, reducing the brain's perception of air hunger.

Gut & Mind - Calm & Quiet

• Nausea & Vomiting:
  • Identify cause: Opioids, metabolic (↑Ca), GI obstruction.
  • Agents: Haloperidol (broad-spectrum), Metoclopramide (prokinetic), Ondansetron (for chemo/radiation).
• Constipation:
  • Opioid-induced is near-universal. Prophylaxis is key.
  • 📌 Mnemonic: "Mush & Push" - Docusate (softener) + Senna/Bisacodyl (stimulant).
  • Methylnaltrexone for refractory cases (doesn't cross BBB).
• Agitation & Delirium (Terminal):
  • First, rule out/treat reversible causes (e.g., pain, urinary retention).
  • Meds: Haloperidol is first-line. Lorazepam for refractory agitation.

⭐ Exam Favorite: Benzodiazepines (e.g., lorazepam) can worsen delirium in the elderly unless it's due to alcohol/benzo withdrawal. Use antipsychotics like haloperidol first.

• Respiratory Secretions ("Death Rattle"):
  • Caused by inability to clear oral secretions. Reposition patient first.
  • Meds: Anticholinergics like Glycopyrrolate or Scopolamine.

High‑Yield Points - ⚡ Biggest Takeaways

• Opioids (morphine) are the cornerstone for managing both pain and dyspnea; titrate to comfort, not fear of respiratory depression.
• The "death rattle" (excess secretions) is treated with anticholinergics like scopolamine or glycopyrrolate.
• For agitation and delirium, haloperidol is the drug of choice, not benzodiazepines, which can worsen confusion.
• Always prescribe prophylactic laxatives (senna, docusate) with opioids to prevent severe constipation.
• The doctrine of double effect ethically justifies providing palliative medications that may unintentionally hasten death.
