After a spinal anesthesia procedure, what is the primary reason to stay flat?

• A. Prevention of spinal headache
• B. Avoid dehydration
• C. Improve digestion
• D. Reduce infection risk

Answer: (A)

After spinal anesthesia, a needle puncture into the dura can allow cerebrospinal fluid to leak. This loss of CSF lowers the pressure inside the skull, and the result can be a post-dural puncture headache. Lying flat helps minimize further CSF leakage and keeps intracranial pressure more stable, reducing both the likelihood and severity of this headache. Hydration, digestion, or infection risk aren't directly tied to the CSF leak mechanism, so they aren't the primary reason to stay flat.
