Logistic regression analysis of risk factors of postpartum hemorrhage of cesarean section / 中国基层医药

ABSTRACT

Objective To investigate the risk actors of postpartum hemorrhage of cesarean section,in order to provide the basis for the prevention of hemorrhage after cesarean section.Methods A case-control study was conducted in 100 cases with postpartum hemorrhage of cesarean section and 200 cases without bleeding of cesarean section.The clinical data were compared and analyzed.The single factor and multiple factors of the Logistic analysis was used to analyze the risk factors of postpartum hemorrhage of cesarean section.Results Fetal macrosomia (OR =3.678,95％ CI1.456-5.345),placenta adhesion (OR =4.264,95％ CI1.556-5.646),placenta praevia (OR =2.754,95％ CI1.754-5.456),multifetal pregnancy (OR =3.964,95％ CI1.274-4.453) were the risk factors of postpartum hemorrhage after cesarean section.Conclusion Evaluation of the above risk factors before cesarean section was important for prevention of postpartum hemorrhage.
