Post Dural Puncture Headache
摘要
Post-dural puncture headache (PDPH) is a common complication of neuraxial anaesthesia, particularly in young patients, females, and obstetric populations. It typically presents within 48 h of dural puncture and is characterized by a postural headache, worsened in the upright position and relieved when supine. Associated symptoms include nausea, neck stiffness, auditory and visual disturbances. The pathophysiology involves cerebrospinal fluid (CSF) hypotension, brain sagging, and cerebral vasodilation. Conservative treatment includes hydration, bed rest, oral analgesics, and caffeine. Epidural blood patch (EBP) remains the gold standard for severe cases, providing symptom relief in up to 80% of patients, though repeat procedures may be necessary.
