What is post-dural puncture headache and how is it managed after regional anesthesia?

• A. CSF leak causing orthostatic headache; management includes bed rest, hydration, caffeine, analgesics; epidural blood patch if persistent.
• B. Migraine-type headache; treat with triptans.
• C. Elevation of intracranial pressure; hyperventilation.
• D. Nausea without headache.

Answer: (A)

Post-dural puncture headache happens when a dural puncture from regional anesthesia creates a leak of CSF. The loss of CSF lowers the pressure around the brain, causing traction on the pain-sensitive meninges. Because CSF pressure rises when you lie down and drops when you sit or stand, the headache is classically orthostatic—it worsens upright and improves when recumbent. It may come with neck stiffness, nausea, photophobia, or ear fullness. Management starts with simple, supportive measures. Ensuring adequate hydration and using caffeine can help, as caffeine briefly constricts cerebral vessels and may boost CSF production. Analgesics are used to control pain, and patients can often rest as tolerated. Epidural blood patch, where a small amount of the patient’s own blood is injected into the epidural space near the puncture site, is reserved for ongoing or very bothersome headaches; it effectively seals the leak and rapidly relieves symptoms in most cases. If the headache does not fit the typical PDPH pattern or does not respond to patching, further evaluation may be needed to rule out other causes.
