Abstract
Background
PDPH is common in the obstetrical population, who frequently receives epidural or spinal
analgesia and anesthesia during labor and delivery. Female sex and young age are reported risk
factors adding additional risks.
Objective
This study will assess the incidence, onset time and severity of PDPH and other symptoms
associated with PDPH, in elective cesarean section patients undergoing spinal anesthesia at
TAH.
Methods
A prospective observational descriptive study was done on ASA I and ASAII patients
scheduled for elective C/S under spinal anesthesia after an informed consent is obtained. The
study was carried out at the maternity operating theatre and maternity wards of TAH. Patients
were contacted by telephone, on the 7th day postoperatively after discharge from hospital. The
study was conducted for a period of 4 months. Approval to conduct the study was obtained
from ethical committee. An interviewer administered data sheet was used as the main
instrument for data collection. Data was analyzed using Statistical package for social sciences
version 20 and presented in tables and pie charts.
Results and conclusion
The incidence of PDPH in elective C/S mothers following spinal anesthesia at TAH maternity
theatre was 38.7%. There was very significant association between needle size and PDPH
incidence. P (0.000), Orientation of the needle bevel perpendicularly to the longitudinal dural
fibres was associated with more risk of develop PDPH compared to parallel orientation p(0.01).
Multiple dural puncture attempts during administration of anesthesia were also associated risk of
development of PDPH as compared to one dural puncture (p=0.02).
