ABSTRACT
Objective To explore the risk factors of postpartum hemorrhage .Methods From January 2015 to January 2017,72 cases with postpartum hemorrhage in Rongjun Hospital of Lyuliang were selected in the present study.Logistic regression analysis was used to screen the risk factors of postpartum hemorrhage ,and put forward corre－sponding preventive measures according to different risk factors ,in order to reduce the incidence of postpartum hemor－rhage.Results Age[the incidence rate of postpartum hemorrhage in patients more than 33 years old was 15.63%(5/32)],childbirth way [ the incidence rate of postpartum hemorrhage in cesarean section patients was 28.57%(4/14),gestational age[the incidence rate of postpartum hemorrhage in patients with gestational age ＜41 weeks was 7.41%(4/54)],placenta previa [the incidence rate of postpartum hemorrhage was 23.08%(6/26)],the birth canal injury[the incidence rate of postpartum hemorrhage was 14.29%(5/35)],uterine inertia[the incidence rate of postpartum hemorrhage was 37.93%(22/58)],blood coagulation dysfunction [the incidence rate of postpartum hemorrhage was 8.33%(2/24)] and placenta conglutination [the incidence rate of postpartum hemorrhage was 23.08%(3/13)]had influence on postpartum hemorrhage ,through the study of the statistical analysis of a single risk factor,found that the differences were statistically significant (χ2＝15.125,22.034,15.125,22.034,7.114,25.147, 26.301,8.226,all P＜0.05).Through the analysis of single factor and multiple factors unconditioned logistic regres －sion analysis,established risk factor model and found that cesarean section ,uterine inertia,placenta conglutination conformed to the analysis results (β＝2.868,1.484,1.173,E.(β)＝0.088,0.086,0.175,S.95%CI＝3.499－22.734,2.889－6.834,1.368－3.894),but statistically significant differences were observed among different factors (OR＝16.746,4.0123,2.379,all P＜0.05).Conclusion Age,childbirth way,gestational age,placenta previa, birth canal injury, uterine inertia, blood coagulation dysfunction and placenta adhesion all can affect postpartum hemorrhage,in the process of childbirth pregnant women ,should have the possibility of various factors are positive and effective prevention,ready to related work and measures ,in patients with postpartum should also increase the intensity of nursing,preventing postpartum hemorrhage occurs .
