Lyn Masters is a 69 year old woman who presents to the Emergency Department with severe back pain and weakness in both legs. She has a past history of breast carcinoma 5 years ago, treated with surgery and adjuvant therapy. She notes a 6 month history of progressive fatigue and pain across the pelvis, spine and ribs. X-rays in ED reveal widespread bone metastases. An urgent MRI of the spine reveals multiple bony metastases with impending spinal cord compression at T12, with extension into the spinal canal and cord oedema.
Spinal cord compression is an oncological emergency requiring immediate intervention to prevent irreversible neurological damage.
| Step | Medication | Notes |
|---|---|---|
| 1. Mild pain | Paracetamol ± NSAIDs | NSAIDs particularly effective for bone pain due to anti-inflammatory effect |
| 2. Moderate pain | Weak opioids (codeine, tramadol) | Often combined with step 1 medications |
| 3. Severe pain | Strong opioids (morphine, oxycodone, fentanyl, hydromorphone) |
• Morphine: Start 5-10mg PO q4h, titrate to effect • Provide breakthrough doses (1/6 of daily dose) • Consider long-acting preparations once stable • Manage side effects: laxatives, anti-emetics |
| Category | Specific Factors |
|---|---|
| Medications |
• Opioids (morphine) – most significant • Anticholinergics (for urge incontinence) • SSRI antidepressant • Other: antiemetics, iron supplements |
| Disease-related |
• Hypercalcemia (bone metastases) • Spinal cord compression/neurological deficit • Bowel obstruction (peritoneal disease) • Dehydration |
| General factors |
• Reduced mobility • Poor oral intake • Weakness • Lack of privacy |
Softener + Stimulant is most effective for opioid-induced constipation
| Laxative Type | Examples | Mechanism | Notes |
|---|---|---|---|
| Softeners (osmotic) |
• Docusate • Macrogol (Movicol) • Lactulose |
Draw water into stool |
• Macrogol preferred (more effective, less bloating than lactulose) • Can be used long-term |
| Stimulants |
• Senna • Bisacodyl • Sodium picosulfate |
Increase peristalsis |
• Senna most commonly used in palliative care • Can cause cramping • Safe for long-term use in palliative setting |
| Combination | Co-danthramer, Co-danthrusate | Softener + stimulant | Convenient single preparation (not available in all countries) |
| Specific for opioid-induced |
• Methylnaltrexone (SC) • Naloxegol (PO) |
Peripheral opioid antagonist |
• Expensive, specialist use • For refractory cases • Does not affect analgesia |
If rectal examination reveals impaction:
If constipation not responding to treatment, consider:
Assess what the patient knows:
Determine how much information the patient wants:
Share information sensitively:
"I'm afraid I have some difficult news to share with you..."
"The oncologist has reviewed your recent scans and blood tests. Unfortunately, the cancer is not responding to the chemotherapy and has continued to grow. The oncologist feels that further chemotherapy is unlikely to help and may cause more side effects and reduce your quality of life."
"Although the oncologist is recommending stopping chemotherapy, this doesn't mean we're giving up or that there's nothing we can do. I'd like to arrange for you to meet with our palliative care team. They are specialists in managing symptoms and supporting people living with serious illnesses. Their goal is to help maintain your quality of life and ensure you're as comfortable as possible."
Acknowledge and respond to emotional reactions:
| Technique | Example |
|---|---|
| Name the emotion | "I can see this news is very upsetting for you" |
| Understand | "This must be very difficult to hear" |
| Respect | "You've shown remarkable strength through all of this treatment" |
| Support | "We're going to support you through this" / "You're not alone" |
| Explore | "Tell me what you're most worried about" |
Develop a plan going forward:
