What is the initial management for a spinal headache?

Initial Management of Spinal Headache

The initial management of spinal headache (postdural puncture headache) should be conservative medical management for up to two weeks, as these headaches are typically self-limited with most symptoms fully resolving within 1 week without any treatment. 1

Conservative Management Approach

• Bed rest with the patient lying flat as much as possible for 1-3 days to reduce CSF pressure gradient and minimize leakage 1, 2
• Adequate hydration to support CSF production 2, 3
• Analgesics for pain relief:
  • Acetaminophen and/or non-steroidal anti-inflammatory drugs (NSAIDs) as first-line therapy 1, 2
  • Caffeine sodium benzoate (500 mg intravenously or orally) can be effective in relieving symptoms 4, 5
• Avoid activities that may exacerbate CSF leakage for 4-6 weeks: bending, straining, stretching, twisting, closed-mouth coughing, sneezing, heavy lifting, strenuous exercise, and constipation 1

When to Consider Epidural Blood Patch

• If symptoms are severe or not beginning to resolve by 2-3 days after dural puncture 1, 2
• For moderate-to-severe postdural puncture headache that is refractory to conservative management 3
• The procedure involves:
  • Injection of 15-20 mL of autologous blood with strict aseptic technique 2
  • Blood should be injected slowly and incrementally 2
  • Patient should lie flat for 1-3 days after the procedure 1

Management of Rebound Headache

• Rebound headaches may occur following epidural blood patch treatment and are usually self-limited and minor 1
• Can be managed conservatively without imaging 1
• Acetazolamide may be prescribed to lower CSF production in cases of severe rebound headache 1
• CSF drainage via lumbar puncture or lumbar drain can be considered in severe cases refractory to medical management 1

Important Considerations and Pitfalls

• Avoid medications that could potentially lower CSF pressure or reduce blood pressure, as they may exacerbate symptoms 2
• Monitor for medication overuse headache in patients using frequent analgesics 2
• Opioids may be required for severe pain but should be avoided for long-term management 1, 2
• Patients should be advised not to drive themselves home after procedures 1

Follow-up Recommendations

• Early review within 24-48 hours after any intervention 2
• Regular assessment of headache severity, time able to spend upright, and associated symptoms 2
• If symptoms persist beyond 1 week despite conservative management, consider referral to a specialist neuroscience center 1

Diagnostic Considerations

• If headache persists beyond 72 hours after dural puncture, an epidural blood patch should be considered rather than imaging 1
• For patients with suspected spontaneous intracranial hypotension (without recent spinal intervention), MRI of the brain and complete spine is required to assist in localizing a potential CSF leak 1
