Continuous Cervical Epidural Analgesia in Metastatic Spinal Cord Compression

Area of Science:

• Oncology
• Pain Medicine
• Neurology

Background:

• Metastatic spinal cord compression (MSCC) is a severe cancer complication.
• Opioid therapy for MSCC pain often leads to adverse effects like myoclonus and sedation.
• Refractory pain in MSCC poses significant management challenges.

Observation:

• A 63-year-old male with malignant spinal cord compression experienced uncontrolled pain despite pharmacotherapy.
• The patient suffered from opioid-induced myoclonus and sedation.
• A continuous cervical epidural catheter with local anesthetic infusion was administered for 5 days.

Findings:

• The epidural infusion provided significant pain relief.
• Sustained pain relief persisted for up to 64 days post-catheter removal.
• This suggests a deafferentation effect on noxious stimuli.

Implications:

• Continuous cervical epidural local anesthetic infusion may be an effective strategy for refractory MSCC pain.
• Central neuraxial blocks offer a potential rescue therapy for selected MSCC patients.
• This approach may reduce reliance on high-dose opioids and their associated side effects.
