Abstract:Objective To explore the reason and high-risk factors for postpartum hemorrhage in second puerpera. Methods The clinical data of 694 second puerpera in Zhaoqing NO.2 People′s Hospital from June 2015 to June 2017 were retrospectively analyzed. Univariate analysis and multiple Logistic regression analysis were applied to identify the related factors for postpartum hemorrhage in second puerpera. Results The incidence rate of postpartum hemorrhage in second puerpera was 11.67%. Univariate analysis showed that the incidence rate of postpartum hemorrhage was significantly increased in second puerpera with one or more of the following factors: age (>35 years), abnormal gestational week (<37 weeks or >42 weeks), cesarean section history, uterine atony, placenta previa, placental adhesion, placental abruption, soft birth canal injury and cesarean section (P < 0.05). Multiple Logistic regression analysis showed that uterine atony, placenta previa, placental adhesion, placental abruption, cesarean section, age (>35 years), abnormal gestational week (<37 weeks or >42 weeks), soft birth canal injury and cesarean section history were the high-risk factors for postpartum hemorrhage in second puerpera (P < 0.05). Conclusion There are various high-risk factors influencing postpartum hemorrhage in second puerpera, hence, targeted countermeasures should be taken to reduce the occurrence of postpartum hemorrhage.
