In planning care after a lumbar puncture, which intervention helps prevent post-procedure complications?

• A. Keep the patient flat for several hours
• B. Encourage vigorous activity
• C. Have the patient walk immediately
• D. Place the patient in Trendelenburg position

Answer: (A)

After a lumbar puncture, a small opening in the dura allows CSF to leak. This leakage can lead to a post-dural puncture headache and other complications if not managed. Keeping the patient flat for several hours minimizes gravity-driven CSF outflow and helps the puncture site seal, reducing the chance of CSF leakage and the associated headache. Moving too soon, via vigorous activity or walking, can aggravate the leak and worsen symptoms. The Trendelenburg position can disrupt intracranial dynamics and is not helpful in this situation. So the flat position directly supports sealing the puncture and stabilizing CSF pressure, preventing post-procedure complications.
