What is the best approach to manage dyspnea (shortness of breath) in patients at the end of life?

Management of Dyspnea at the End of Life

Opioids are the most effective and widely studied agents for palliation of dyspnea in end-of-life patients and should be the mainstay of pharmacological management, with benzodiazepines as adjunctive therapy for associated anxiety. 1, 2

Assessment and Initial Approach

• Regularly assess patients with serious illness at the end of life for dyspnea, as it is one of the most distressing symptoms experienced by dying patients 1, 2
• For non-communicative patients, use physical signs of respiratory distress such as labored breathing as indicators of potential dyspnea 1
• Determine the estimated life expectancy (years, months to weeks, or weeks to days) to guide appropriate intervention strategies 1

Treatment Algorithm Based on Life Expectancy

For Patients with Years of Life Expectancy:

• Treat underlying causes and comorbid conditions when appropriate:
  • Consider radiation/chemotherapy for malignancies 1
  • Implement therapeutic procedures for cardiac, pleural, or abdominal fluid 1
  • Use bronchoscopic therapy, bronchodilators, diuretics, steroids, antibiotics, or transfusions as indicated 1
  • Administer anticoagulants for pulmonary emboli 1
• Provide symptomatic relief:
  • Offer oxygen therapy for patients with hypoxemia or those reporting subjective relief 1
  • Implement nonpharmacologic interventions including fans, cooler temperatures, stress management, and relaxation therapy 1, 3
  • Provide educational, psychosocial, and emotional support for the patient and family 1

For Patients with Months to Weeks of Life Expectancy:

• If opioid naïve, administer morphine 2.5-10 mg PO every 2 hours as needed or 1-3 mg IV every 2 hours as needed 1
• If already on chronic opioids, consider increasing the dose by 25% 1
• For dyspnea associated with anxiety, add benzodiazepines (if benzodiazepine naïve, start with lorazepam 0.5-1 mg PO every 4 hours as needed) 1, 2
• Consider noninvasive positive-pressure ventilation (CPAP, BiPAP) only if clinically indicated for severe reversible conditions 1
• If fluid overload is contributing:
  • Decrease or discontinue enteral or parenteral fluid 1
  • Consider low-dose diuretics 1
• Manage excessive secretions with:
  • Scopolamine 0.4 mg subcutaneous every 4 hours as needed or 1.5 mg patches (1-3 patches every 3 days) 1
  • Alternative options: atropine 1% ophthalmic solution 1-2 drops sublingually every 4 hours as needed, or glycopyrrolate 0.2-0.4 mg IV or subcutaneous every 4 hours as needed 1
• Provide anticipatory guidance for patient and family regarding the dying process related to respiratory failure 1
• Offer emotional and spiritual support 1

For Patients with Weeks to Days of Life Expectancy (Actively Dying):

• Intensify palliative care interventions and consider consultation with a palliative care specialist 1
• Consider sedation for intractable symptoms when other measures fail 1
• Continue aggressive symptom management focused on comfort 1, 2

Special Considerations

• For acute progressive dyspnea, more aggressive opioid titration may be required 1
• Early involvement of palliative care specialists and/or hospice services facilitates optimal symptom management and transitions of care 2
• A simple fan directed at the face can provide significant relief and should be considered given its minimal burden and cost 3
• Address advance care planning, including discussions about mechanical ventilation preferences, to prepare for potential respiratory decline 4

Common Pitfalls to Avoid

• Undertreatment of dyspnea due to concerns about respiratory depression from opioids; evidence supports their safety and efficacy when appropriately dosed 1, 5
• Overreliance on oxygen therapy in non-hypoxemic patients; while it may provide subjective relief for some, it is not universally beneficial 1, 3
• Failure to address the psychological and emotional components of dyspnea, which can significantly amplify the symptom 2, 5
• Delaying palliative interventions until the very end of life; early implementation of symptom management strategies improves quality of life 1, 4
