The Comparison of Post-dural Puncture Headache- Frequency and Severity on Cesarean Patients that Spinal Anaesthesia Performed with 25G, 27G and 29G Quincke Needles

Objective: the aim of this study is to compare the frequency and severity of post-dural puncture headache (pdph) between the cesarean patients that was spinal anaesthesia performed with 25g, 27g and 29g quincke needles. material-method: following the approval of clinical researches local ethics committee 60 asa i-ii clinical status patients above 18 years that cesarean section was planned included in the study. patients were ramdomised to three groups. the spinal anaesthesia was performed with 25g guided quincke sharp-tipped needle to group i (n=20), with 27g needle in group ii (n=20) and with 29g needle in group iii (n=25). general anesthesia was performed in unsuccessful spinal anaesthesia patients and they were excluded from the study. the pdph, the time and the severity till the second week of the operation and was asked and reported. the severity was degreed according to lybecker classification. results: pdph was reported on 9 of total 60 patients (15.0%). the distribution was as: 5 patients in group i (25.0%), 3 patients in group ii (15.0%), and 1 patient in group iii (5.0%). severe pdph was occurred in 2 patients in group i and was not occurred in any patients in group ii and iii. there was no significany difference istatistically between groups by the means of pdph. conclusions: at least for preventing the risk, although there is no statistically difference between different needle sizes; we think that 29g guided needle may be preferred in the clinical practice if available.
