What is the recommended posture after spinal anesthesia to minimize headache risk?

• A. Flat on bed for 6 to 8 hours
• B. Sitting upright for 1 hour
• C. Standing
• D. Lying on the side with head down

Answer: (A)

The main idea is to keep CSF pressure stable to prevent leakage from the puncture and reduce brain sag that can cause a post-spinal headache. Lying flat in bed for about 6 to 8 hours after spinal anesthesia does this best by minimizing gravitational flow of CSF and giving the puncture site a chance to seal. Positions that are upright or standing increase CSF leakage and raise the risk of headache. A head-down side-lying position isn’t used for this purpose because it doesn’t offer the same protection against CSF leakage and can bring other complications. So staying flat for several hours is the most effective way to minimize headache risk.
