Factors Associated with Postdural Puncture Headache in Woman who Undergo Caesarean Section under Spinal Anesthesia in Tertiary Hospital, Parsa

Background: Postdural puncture headache is one of the second most common complications of spinal anesthesia. This study aimed to find out the factors associated with postdural puncture headache in woman who undergo caesarean section delivery under spinal anesthesia. Methods: A descriptive cross-sectional research design was used. A total of ninety four pregnant mothers who underwent caesarean section delivery under spinal anesthesia were selected by purposive sampling method. A structured interview schedule and observational checklist were used for data collection from Dec 25, 2022 to Jan 7, 2023. Data were entered into the SPSS 20 version and were analysed by using descriptive and inferential statistics. Results: This study shows mean age of the respondents was 25.26+2.87, only 6.4% had developed postdural puncture headache, among more than half (66.7%) of the respondents had raised their heads before 24 hours of anesthesia, about 50% of respondents had a worse headache while raising their head with a pillow and experienced headache within 15min after raising the head. Repeated attempts of spinal anesthesia (p-value is 0.0001) had a statistically significant association with postdural puncture headache. Conclusions: These findings concluded that the incidence of PDPH is 6.4% in caesarean section delivery under spinal anesthesia and multiple attempts contribute to increased PDPH suggesting that repeated attempts of spinal should be minimized to decrease the incidence of post-dural puncture headache.
