Abstract
INTODUCTION: - Hypotension is a 20% to 30% reduction in systolic blood pressure,
comparing it to initial values or absolute systolic blood pressure values between 100 mmHg
and 90 mmHg. Hypotension during spinal anesthesia for cesarean section is one of the most
common complication which decreases uteroplacental perfusion.
OBJECTIVES: - To assess incidence and risk factors of post spinal hypotension among
pregnant mothers who delivered by elective cesarean sections from January to February
2016
at Gandhi Memorial Hospital, Addis Ababa.
METHODS: - Institution based cross sectional study design was conducted. All list of pregnant
mothers who gave birth by elective cesarean section under spinal anesthesia at Gandhi Memorial
Hospital were included. Training was given for data collectors and supervisors. Regular
supervision and follow up made. Data was entered in to Epi info version 7 software and transported
to SPSS version 20 for analysis. Odd ratio and 95% confidence interval was computed. Bivariate
and Multivariate analysis used to identify factors associated with hypotension.
RESULTS: - The study was conducted on 60 study participants. 24(40%) were equally found
between 25-29 years and 30-34 years. The incidence of hypotension was 80% during five to fifteen
minute and 83% during fifteen to twenty five minute. 70% of the study participants were preloaded
with more than 500ml of crystalloid and 60% were took oxytocin for uterine contraction. Majority
of them were positioned in supine position prior to spinal anesthesia.
CONCLUSION AND RECCOMENDATION: -The incidence of hypotension was high so that
vigorous fluid resuscitation and the use of prophylactic vasopressor were recommended.
