A Randomized, Double-Blind Clinical Trial Comparing the 22 Versus 26 Gauge Needle in the Production of the Post-Lumbar Puncture Syndrome in Normal Individuals

Key Points

• This trial aims to compare the incidence of post-lumbar puncture syndrome between two gauge needle sizes in normal individuals.
• Conducted as a randomized, double-blind clinical trial
• Involved normal individuals receiving either a 22 or 26 gauge needle during lumbar puncture
• Evaluated the occurrence of post-lumbar puncture syndrome
• The 22 gauge needle group exhibited a higher incidence of post-lumbar puncture syndrome compared to the 26 gauge needle group.
• Statistical significance for the difference in incidence was observed, indicating a potential preference for the 26 gauge needle.
