Analysis of Factors Affecting Postpartum Hemorrhage in Twin Pregnancy

Abstract

Objective: To explore the factors affecting postpartum hemorrhage in twin pregnancy. Methods: The clinical data of 839 twin pregnancy patients who delivered at the Second Hospital of Shandong University from May 2010 to July 2020 were retrospectively analyzed. According to the amount of postpartum hemorrhage, patients were divided into postpartum hemorrhage group (PPH group) and non- PPH group. The basic population information and clinical data during pregnancy were compared between the two groups. Results: A total of 839 women with twin pregnancy were included in this study, and hemorrhage occurred in 11% (n=96). The Binary logistic regression model predicts the risk of factor of postpartum hemorrhage in twin pregnancy: gestation week of delivery, placenta previa, polyhydramnios, acute delivery, anemia, placental adhesions and DIC (disseminated intravascular coagulation). Conclusions: There are many factors that affect postpartum hemorrhage in twin pregnancy. Choosing the right gestational week for delivery, strengthening pregnancy management, and improving pregnancy complications can reduce the risk of postpartum hemorrhage in twin pregnancy.
