Methodology: This was a prospective study of 100 patients undergoing surgery under spinal anesthesia. The subjects were divided in two groups. In group I, the anesthesia was applied with 25G quincke needle and in group II, the anesthesia was applied with 27G quincke needle. The patients were evaluated for post dural puncture headache till 72 hours postoperatively. Chi-square test was applied. P <0.05 was taken as significant.
Results: PDPH was seen in 14 (28%) subjects in group I and in 4 (8%) subjects in group II.
Conclusion: 27G needle should be preferred over 25G needle for application of spinal anesthesia due to decreased PDPH
