Abstract
BackgroundSpinal anesthesia is a type of regional anesthesia that has been practicing for obstetric anesthesia since the beginning of the 20th century. Despite the simplicity and lower maternal mortality risk, compared to general anesthesia, spinal anesthesia is linked to different adverse effects, of which hypotension is the most common complication. The main aim of this study was to determine the incidence and associated factors of hypotension after spinal anesthesia during cesarean section.MethodInstitution-based cross-sectional study was conducted with 410 clients. The study was conducted on cesarean section under spinal anesthesia from 5th January to 30th April 2019, at the Gandhi Memorial Hospital, Addis Ababa, Ethiopia. Both bivariable and multivariable logistic regression analysis were done on the associated factors. The level of statistical significance was represented at p<0.05.ResultsThe incidence of hypotension among mothers who underwent a cesarean section after spinal anesthesia was 64%. Newborn weight ≥4kg (AOR = 5.373; 95%CI: (1.627–17.740)) showed an increase risk of association with hypotension. A baseline systolic blood pressure < 120mmHg (AOR = 6.293; (95%CI: 2.999–13.204)) was found to be associated with increased risk of hypotension. Sensory block height >T6 AOR = 2.230; 95%CI: (1.329–3.741), the time interval between spinal induction and skin incision > 6minutes AOR = 1.803; 95%CI: (1.044–3.114) and anesthetist experience AOR = 5.033(95%CI: 2.144–11.818) were also associated with hypotension.ConclusionThe identified risk factors for hypotension, after spinal anesthesia are sensory height block, weight of the baby, the time interval between spinal induction and skin incision, baseline systolic blood pressure, and anesthetist experience.

Summary
In Ethiopia, there is a high increase in practice of spinal anesthesia [1] Spinal anesthesia is preferred by both mothers and health professionals because of its unique advantages. The incidence of hypotension is 25–75% in general population and even higher in parturient who are undergoing cesarean section due to physiological change of pregnancy that causes compression of inferior vena cava by hypertrophic uterus and the development of collateral venous plexus circulation in epidural space. This physiological change results in increased pressure of the cerebrospinal fluid (CSF) in the lumbosacral area, which results in cephalad spread of local anesthetics [3,4,5]. The main aim of this study was to determine the incidence and associated factors of hypotension after spinal anesthesia during cesarean section
