Abstract
TAVARA, Angie; NUNEZ, Maritza and TRESIERRA, Miguel Ángel. Factors associated with uterine atony. Rev. peru. ginecol. obstet. [online]. 2022, vol.68, n.2, 00005. Epub July 06, 2022. ISSN 2304-5132. http://dx.doi.org/10.31403/rpgo.v68i2424.
Postpartum hemorrhage (PPH) is the most important pathology in terms of maternal mortality, being one of the main public health concerns. Uterine atony is the main cause of PPH.
Objective
: To determine the factors associated with the development of uterine atony.
Methods
: Observational analytical case-control study of 4,148 immediate postpartum patients attended at the Obstetrics Department of the Hospital Regional Docente de Trujillo, Peru, between 2009 and 2019; 1,037 patients presented uterine atony and 3,111 were controls.
Results
: When performing the bivariate analysis, the variables that presented statistical significance as associated factors for the development of uterine atony were cesarean delivery [OR 1.98 (95% CI: 1.71-2.29)], being from the highlands [OR 1.38 (95% CI: 1.12-1.70)], multiple pregnancy [OR 4.48 (95% CI: 3.43-5.83)], dysfunctional delivery [OR 1.82 (95% CI: 1.44-2.31)] and macrosomic fetus [OR 1.37 (95% CI: 1.08-1.73)]. On the other hand, having been primiparous [OR 0.79 (95% CI: 0.65-0.94)] and being multiparous [OR 0.82 (95% CI: 0.69-0.97)] were shown as factors not associated with statistical significance.
Conclusions
: Factors associated with the development of uterine atony were cesarean section as the route of delivery, being from the highlands, and having had a macrosomic fetus, polyhydramnios and multiple pregnancies.
