Which neuraxial anesthesia complication is described as a puncture of the dura mater with the epidural needle leading to a CSF leak and spinal headache?

• A. Inadvertent puncture of the Dura mater membrane with epidural needle, CSF leak, causing spinal headache
• B. Infection at the injection site
• C. Catheter migration
• D. Delayed respiratory depression

Answer: (A)

Dural puncture during neuraxial anesthesia allows CSF to leak from the intrathecal space, creating intracranial hypotension that leads to a post-dural puncture headache. This headache is classically orthostatic—worse when upright and relieved by lying down—and may be accompanied by neck stiffness, nausea, and photophobia. The mechanism is loss of CSF volume and pressure, causing traction on pain-sensitive structures as the brain sags slightly when upright. Management focuses on sealing the leak and alleviating symptoms, with options ranging from conservative measures (hydration, caffeine, analgesia, bed rest) to an epidural blood patch for persistent or significant headaches. This scenario is distinct from infection at the injection site, catheter migration, or delayed respiratory depression, which present with different signs and causes not related to CSF leakage.
