Initial Management of Headache Due to Dural Tear

Diagnosis and Clinical Presentation

Post-dural puncture headache (PDPH) typically presents as a postural headache that worsens when upright and improves when lying flat, occurring within 5 days of a dural puncture 1
The headache is often accompanied by neck stiffness and/or subjective auditory symptoms 1
The incidence varies widely (2-40%) depending on procedural and patient factors 1
Younger age and female sex are associated with a higher risk of PDPH 1

Maintain adequate hydration with oral fluids 2
Offer regular multimodal analgesia including acetaminophen and NSAIDs to all patients unless contraindicated 2
Short-term opioids may be considered if multimodal analgesia is ineffective 2
Avoid long-term opioid use 2
Administer caffeine in the first 24 hours of symptoms 2
Maximum dose: 900 mg per day (200-300 mg if breastfeeding) 2
Caution: Excessive caffeine may cause adverse effects including withdrawal, dehydration, and seizures 3

Epidural Blood Patch (EBP) should be performed without the need for initial imaging studies 4
For known dural puncture sites, the EBP should be directed at the level of the puncture 4
The effectiveness of EBP is evident by a marked decrease in pain intensity approximately 4 hours after the procedure 1

Consider leaving an intrathecal catheter in place for 24 hours to potentially decrease the chance of developing PDPH 5
Ensure adequate labeling of the intrathecal catheter and take precautions to avoid CSF leakage 5
Consider injecting sterile saline into the intrathecal catheter, though evidence for this effect is limited 5

Follow up with patients until headache resolves 6
Monitor for potential complications:
- Chronic headache 1
- Cerebral venous sinus thrombosis 1

Worsening symptoms despite an EBP 6
New focal neurological symptoms 6
Change in the nature of headache 6
Urgent neuroimaging and specialist referral should be performed if any of these occur 6

Unnecessary imaging studies during the first 72 hours, which may delay definitive treatment 4
Inadequate follow-up arrangements, which may lead to missed complications 6
