Why the study?
Does spinal anaesthesia using a 29-gauge spinal needle reduce the incidence of post-dural puncture headache compared to a 25-gauge spinal needle in pregnant women undergoing LSCS?
Does spinal anaesthesia using a 29-gauge spinal needle reduce the incidence of post-dural puncture headache compared to a 25-gauge spinal needle in pregnant women undergoing LSCS?
The use of a 29-gauge spinal needle significantly reduces the incidence of post-dural puncture headache compared to a 25-gauge needle in pregnant women undergoing caesarean section, although it may require more attempts for successful dural puncture.

May support finer needles to reduce PDPH in obstetric spinal anaesthesia; leaves open confirmation in randomized trials.
Incidence of post-dural puncture headache varies from 0% to 16% depending upon the gauge of spinal needle used. A nonrandomised controlled trial study was conducted to compare the incidence of post-dural headache in spinal anaesthesia using 25gauge and 29-gauge spinal needle. 100 patients between 18 and 40 years age belonging to ASA group I and II of pregnant female patient were taken to receive a spinal anaesthesia with 25-gauge/ 29-gauge spinal needle for LSCS operation. The incidence, type, severity, day of onset and site of post-dural punctured headache was recorded for first 4 operative days and data obtained was analysed for any significant difference among the two groups. Incidence of post-dural spinal headache was significantly high in patients on whom 25-gauge spinal needle was used as compared to those with 29-gauge spinal needle.
