Study on risk factors of postpartum hemorrhage in elderly parturients after cesarean section

Abstract

Objective To investigate the risk factors of postpartum hemorrhage in elderly parturients after cesarean section based on logistic regression analysis and to explore nursing strategies. Methods From January 2018 to March 2019, a total of 210 elderly women with cesarean section and postpartum hemorrhage in the Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were selected as the study group.And 420 elderly women who underwent cesarean section and did not have bleeding were selected as the control group, which may cause postoperative bleeding.Factors were analyzed and multivariate logistic regression analysis was performed on the factors that caused significant effects. Results The incidence of pregnancy hypertension, abortion history, uterine atony, macrosomia and placenta previa in the observation group was significantly higher than that in the control group (t=4.118-83.345, P=0.000-0.042). There were no statistically significant differences in gestational diabetes mellitus, postpartum hemorrhage, coagulation function and depression between the two groups(t=0.006-0.788, P=0.375-0.938). Multivariate logistic regression analysis showed that gestational hypertension, history of abortion, uterine atony, macrosomia and placenta previa were risk factors for postpartum hemorrhage in elderly parturients after cesarean section (OR=2.114-19.521, P=0.035-0.001). Conclusion Pregnancy-induced hypertension, history of abortion, uterine atony, macrosomia and placenta previa are the main factors affecting postpartum hemorrhage in elderly women with cesarean section.This provides an effective basis for the nursing of cesarean section postpartum hemorrhage in elderly women.
