| description | Coordinates multidisciplinary treatment with palliative care unit for pain management while avoiding medications that risk inducing hypertensive crisis (e.g., metoclopramide, certain antidepressants) in PPGL patients. Triggered by reports of pain in PPGL patient, especially with bone involvement. |
Apply precautions for pain management in pheochromocytoma and paraganglioma
STEP 1 — Gather Information
Collect pain characteristics (location, severity, quality), assess for bone metastases via imaging or symptoms, review current medications (especially metoclopramide, antidepressants, dexamethasone), and evaluate palliative care needs. → Proceed to medication risk screening.
STEP 2 — Rule In / Rule Out
Is the patient taking any medication known to induce hypertensive crisis (e.g., metoclopramide, tricyclic antidepressants, SNRIs, MAO inhibitors, high-dose dexamethasone)? If yes, discontinue or avoid these agents; if no, proceed to analgesic selection.
STEP 3 — Classify or Stratify
Classify pain severity using WHO analgesic ladder (mild, moderate, severe) and assess for skeletal-related events (spinal cord compression, hypercalcemia, pathological fractures). → Determine analgesic step and need for adjuvant therapy or bone-directed treatment.
STEP 4 — Decide
Initiate multidisciplinary pain management with palliative care unit, select analgesics per WHO ladder avoiding high-risk agents, consider bone-modifying agents (e.g., zoledronic acid) or radiotherapy for bone metastases, and monitor for side effects and blood pressure.
Clinical Guardrails / Mimics / Pitfalls
Do not use metoclopramide for nausea/vomiting due to hypertensive crisis risk; avoid tricyclic antidepressants and SNRIs for neuropathic pain; avoid high-dose dexamethasone; use opioids with prophylactic laxatives to prevent constipation; avoid NSAIDs if renal impairment; ensure blood pressure monitoring during analgesic initiation.
Concrete Clinical Example
A 58-year-old patient with metastatic PPGL to lumbar spine reports worsening back pain (7/10) despite acetaminophen. Current meds include metoclopramide for nausea. Discontinue metoclopramide, start low-dose morphine with laxative, involve palliative care for opioid titration, add zoledronic acid for bone lesions, and coordinate radiotherapy if pain persists.
