BackgroundrnPDPH is common in the obstetrical population, who frequently receives epidural or spinalrnanalgesia and anesthesia during labor and delivery. Female sex and young age are reported riskrnfactors adding additional risks.rnObjectivernThis study will assess the incidence, onset time and severity of PDPH and other symptomsrnassociated with PDPH, in elective cesarean section patients undergoing spinal anesthesia atrnTAH.rnMethodsrnA prospective observational descriptive study was done on ASA I and ASAII patientsrnscheduled for elective C/S under spinal anesthesia after an informed consent is obtained. Thernstudy was carried out at the maternity operating theatre and maternity wards of TAH. Patientsrnwere contacted by telephone, on the 7th day postoperatively after discharge from hospital. Thernstudy was conducted for a period of 4 months. Approval to conduct the study was obtainedrnfrom ethical committee. An interviewer administered data sheet was used as the mainrninstrument for data collection. Data was analyzed using Statistical package for social sciencesrnversion 20 and presented in tables and pie charts.rnResults and conclusionrnThe incidence of PDPH in elective C/S mothers following spinal anesthesia at TAH maternityrntheatre was 38.7%. There was very significant association between needle size and PDPHrnincidence. P (0.000), Orientation of the needle bevel perpendicularly to the longitudinal duralrnfibres was associated with more risk of develop PDPH compared to parallel orientation p(0.01).rnMultiple dural puncture attempts during administration of anesthesia were also associated risk ofrndevelopment of PDPH as compared to one dural puncture (p=0.02).rn9rnThe incidence of PDPH is higher in obstetric patients of TAH
