    (Universidad Privada Norbert Wiener, 2023-01-26) Figueroa Parian, Dinna María; Ayala Peralta, Félix Dasio
    Results: 31 studies were selected. The prevalence of uterine atony ranges from 1.1% to 48.5%. The sociodemographic factors are Hispanic ethnicity with an odds ratio (OR) of 1.24 to 2.1; Asian OR = 1.45 to 1.72; African American OR = 0.99 to 1.14; and advanced maternal age OR = 1.7 to 7.9. Maternal history and comorbidities were: previous postpartum hemorrhage OR = 1.47 to 22.7; previous cesarean section OR = 1.02 to 8.3; previous anemia OR = 1.84 to 4.27; hypertension OR = 1.63 to 4.90; diabetes OR = 1.11 to 1.28; and uterine fibroids OR = 0.74 to 1.84. In pregnancy, fetal macrosomia OR = 1.21 to 6.28; multiple gestation OR = 1.17 to 8.0; placenta previa OR = 3.91 to 9.75; and polyhydramnios OR = 1.0 to 5.97; and labor associated with uterine atony reports prolonged labor OR = 1.30 to 5.24; use of oxytocin OR = 1.04 to 2.97; induction of labor OR = 1.12 to 1.54; chorioamnionitis OR = 1.08 to 4.38; perineal tear OR = 1.27 to 2.12; vaginal trauma OR = 1.56 to 3.07; cervical tear OR = 3.70 to 8.37; and instrumental vaginal delivery OR = 1.05 to 1.88. Conclusions: The prevalence of uterine atony ranges from 1.1% to 48.5%. The main associated factors are ethnicity, advanced maternal age, previous postpartum hemorrhage, previous cesarean section, macrosomia, multiple gestation, placenta previa, prolonged labor, use of oxytocin, induction of labor, chorioamnionitis, perineal tear, and cervical tear.
