Aim: The rate of postdural puncture headache (PDPH) was compared after caesarean section with spinal anesthesia using the 25 gauge spinal needle with the 27 gauge.
Methods: Present study is a randomized clinical trial and 220 full term women entered for caesarean section. We entered full term women randomly for spinal anesthesia with the 25 gauge (group A) and 27 gauge (group B) Quincke spinal needles. In 3 postoperative days, we fallowed and compared Participants in 2 groups for the rate and severity of PDPH. PDPH was defined occipital or frontal headache that made hard the position on sitting or standing.
Results: Data of 220 patients were analyzed. The rate of PDPH was significantly higher in women in group A compared to group B at first (P=0.015), second (P=0.037) and third (P=0.005) follow up days. The severity of the PDPH was not significantly different between 2 groups in three follow up days. The rate of success in spinal anesthesia achievement was not significantly different between 2 groups.
Conclusion: The results of present study recommended that the size of spinal needle can effect on the rate of PDPH after caesarean section.
