Discussion

Prospective comparative study shows 27G needles reduce PDPH incidence and severity in 80 patients, implying better clinical outcomes than 25G.

27G needles reduced PDPH incidence to 12.5% compared to 30.0% for 25G, indicating significant benefit.
First-attempt procedural success was 75.0% with 27G versus 55.0% with 25G needles, showcasing technical advantages.
Statistical analysis utilized Chi-square and t-tests to assess outcomes, with a significant p-value threshold of <0.05.
The findings indicate that 27G needles lead to fewer headache symptoms and complications such as longer hospital stays.

Khan et al. (2025) studied this question.
