Analysis of influencing factors of severe postpartum hemorrhage
Objective To investigate the independent risk factors of severe postpartum hemorrhage(PPH)in parturient women.Methods A total of 536 paraparients with PPH admitted to Jiujiang Maternal and Child Health Hospital from De-cember 2016 to December 2021 were retrospectively selected as the research objects,and they were divided into non-severe PPH group(n=125)and severe PPH group(n=411)according to the severity of PPH.Univariate analysis and logistic regres-sion analysis were used to investigate the risk factors of severe PPH in parturients.Results The non-severe PPH group and the severe PPH group accounted for 2.1％and 0.49％of all women giving birth,respectively.Unifactor analysis showed that there were statistically significant differences in age,pre-pregnancy body mass index(BMI),delivery times,cesarean section history,excessive amniotic fluid,birth weight,multiple pregnancy,severe preeclampsia,chorioamniitis,prolonged labor,de-livery mode and general anesthesia between the two groups(P＜0.05).The results of multivariate analysis showed that histo-ry of cesarean section(β=0.884,OR=3.15,95％CI=1.02-10.30),prolonged labor(β=1.821,OR=3.62,95％CI=3.21-4.03)and emergency cesarean section(β=0.835,OR=4.75,95％CI=1.32-12.96)were independent risk factors for se-vere PPH(P＜0.05).Conclusion Women who have history of cesarean section,prolonged labor and emergency cesarean sec-tion need to pay attention to avoid unnecessary cesarean section,long delivery and emergency cesarean section incidence,and reduce the occurrence of severe PPH.
