Characteristics and factors associated with Uterine Atony in postpartum cesarean women in a Social Security Hospital, 2018- 2023
(Universidad Privada Norbert Wiener, 2024-08-10) Ayala Caballero, Geraldine Andrea; Espinoza Pacheco, Jorge Luis
Objective: To determine the factors associated with uterine atony in cesarean postpartum women at Hospital Suárez Angamos III during the period 2018 to 2023. Material and methods: Quantitative, analytical observational case-control study. The sample size was 144, with uterine atony as the outcome variable and sociodemographic, clinical, and laboratory covariates. A data collection sheet was used, along with descriptive and analytical statistics, calculating the crude and adjusted Odds Ratio (OR) with a significance level of p<0.05. Results: 29.17% (n=14) were over 35 years old, the median blood loss volume was 800cc (IQR: 500-2700), 62.5% (n=30) had comorbidities, 72.92% (n=35) had adequate prenatal care, 25% (n=12) had a long inter-pregnancy interval, 8.33% (n=4) had a history of uterine atony, 50% (n=24) had multiparity, 56.25% (n=27) had previous severe preeclampsia, 91.67% (n=44) had thrombocytopenia, and 79.17% (n=38) had anemia. In the crude and adjusted models using Poisson regression, no statistically significant association with uterine atony was reported. Conclusion: No statistically significant associations were found between uterine atony and sociodemographic, clinical, or laboratory factors in cesarean postpartum women.

Factors associated with postpartum hemorrhage in immediate postpartum women treated at the National Hospital Guillermo Almenara Irigoyen, 2020
(Universidad Privada Norbert Wiener, 2022-12-01) Sanchez Rodríguez, Ena Del Pilar; Sanz Ramirez, Ana María
Objective: To determine the factors associated with postpartum hemorrhage in puerperal women attended at the Hospital Nacional Guillermo Almenara Irigoyen in 2020. Method: The proposed study was a retrospective analytical cross-sectional study with a non-experimental design of cases and controls. The sample consisted of 406 immediate puerperal women, with 203 cases and 203 controls. Results: The sociodemographic factors that had a significant association with postpartum hemorrhage were age (p=0.009) (OR=2.4) and occupation (p=0.021) (OR=1.9). The obstetric factors that had a significant association with postpartum hemorrhage were uncontrolled pregnancies (0.000) (OR=4.1), multiparity (0.016) (OR=3.5), anemia during pregnancy (0.012) (OR=2.2), cesarean section (0.001) (OR=5.2), prolonged labor (0.000) (OR=6.8), retained placental remnants (0.022) (OR=4.2), uterine rupture (0.000) (OR=3.3), uterine atony (0.014) (OR=5.4), perineal tear (0.000) (OR=2.3), and uterine inversion (0.004) (OR=4.8). Conclusion: The study concludes that there are sociodemographic and obstetric factors associated with postpartum hemorrhage in puerperal women.

Postpartum hemorrhage due to uterine atony
(Universidad Privada Norbert Wiener, 2022-02-10) Quispe Cossio, Dalila Isabel; Velasquez Rojas, Yesabella Natali; Rodriguez Chávez, Carlos Leonidas
This case presents a 41-year-old patient, a grand multipara with a history of 5 vaginal deliveries, one of which was macrosomic. Additionally, she has mild preeclampsia. She is admitted at 3 centimeters dilated and experiences hypodynamia during labor, which leads to the stimulation of labor. The delivery initially progresses normally, but then uterine atony develops, which is managed with the application of the red code.

Uso de misoprostol en la prevención de hemorragia posparto en puérperas inmediatas atendidas en un hospital de nivel III en Lima, enero 2024
(Universidad Privada Norbert Wiener, 2025-11-26) Méndez Cotrina, Mervin Erika; Sanz Ramírez, Ana María
Objetivo: Describir el uso de misoprostol en la prevención de la hemorragia posparto en puérperas inmediatas atendidas en un hospital de nivel III en Lima, enero 2024. Material y Método: Enfoque cuantitativo, diseño observacional, descriptivo básico, retrospectivo y transversal. Muestra 74 historias clínicas. Técnica: Análisis documental. Instrumento: ficha de recolección de datos. Análisis descriptivo mediante SPSS. Resultados: los principales factores de riesgo para HPP: multiparidad 89.2%, edad materna avanzada 63.5%, cesárea anterior 4.1%. Principales causas de HPP: macrosomía fetal 2.7%, parto precipitado 2.7%, retención de restos placentarios 23%. El 98.6 % contractura uterina con loquios normales desde los 30 minutos posparto; 25.7 % loquios abundantes. Hipotonía y sangrado activo fueron aislados (≤ 2.8 %). Efectos adversos según dosis administrada de misoprostol: 7% con 400 mcg: 60 % escalofríos y 40% ningún efecto. El 9% con 600 mcg:14.3% náuseas y cefaleas, 100% escalofríos. 84% con 800mcg: 8.1% nauseas, 4.8% vómitos, 17.7% cefalea, 100% escalofríos. Efectos adversos según vía de administración; 6.8% por vía SL: 60% escalofríos, 40% ningún efecto; 87.8% por vía IR: 7.7% nauseas, 4.6% vómitos, 16.9% cefaleas, 100% escalofríos; finalmente, 5.4% por vía IR+ SL: 25% náuseas y cefalea, 100% escalofríos. Conclusiones: El uso de misoprostol favorece en la contractilidad uterina, y estabilidad hemodinámica en la mayoría de puérperas inmediatas, la vía de administración intrarectal presentó mayores efectos adversos, el principal factor de riesgo y causa fueron la multiparidad y retención de restos placentarios respectivamente.

UTERINE ATONY AS A RISK FACTOR ASCIATED TO POSTPARTUM HEMORRHAGE
(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.
