How can a spinal headache be prevented after spinal anesthesia?

• A. Keep client supine
• B. Encourage rapid ambulation
• C. Provide caffeine within 30 minutes
• D. Hydrate only with IV fluids

Answer: (A)

Spinal headaches after regional anesthesia come from CSF leaking through the puncture site, lowering intracranial CSF pressure and allowing the brain to sag slightly, which triggers the characteristic post-dural puncture headache. Keeping the patient flat reduces the pressure gradient and minimizes further CSF leakage, giving time for the puncture to seal and for symptoms to be prevented or minimized. Early ambulation or movement can worsen the leak and provoke or intensify the headache, so rapid up-and-about activity is not preventive. Caffeine can help treat PDPH in some cases by causing cerebral vasoconstriction, but it’s not a reliable preventive measure. Hydration is supportive but, by itself, does not reliably prevent the leak or the onset of PDPH. Therefore, maintaining a supine position after spinal anesthesia is the best preventive approach.
