To prevent headache after spinal anesthesia, the patient should be positioned

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

Answer: (A)

Keeping the patient lying flat after spinal anesthesia helps prevent post‑dural puncture headache. When the dura is punctured, CSF can leak, and the headache occurs mainly when CSF volume and pressure drop, especially with upright positioning. A flat position minimizes the gravitational pull that promotes CSF leakage and reduces brain sagging, giving the puncture site a better chance to seal and CSF pressure to stabilize. That’s why staying supine on the bed for about 6 to 8 hours is the preferred preventive approach. Being upright or standing would increase the CSF pressure gradient and worsen or provoke headache, while a head-down or side-lying position isn’t as effective for this preventive goal.
