Analysis of related influencing factors and management measures for postoperative bleeding after cesarean section in parturient women with placenta previa
Objective To explore the influencing factors of postoperative bleeding after cesarean section in parturient women with placenta previa,and to guide the development of relevant management measures.Methods A retrospective analysis was conducted on 86 parturient women with placenta previa after cesarean section admitted to the First Hospital of Putian City from February 2020 to December 2022.They were divided into a bleeding group and a nonbleeding group based on whether postpartum bleeding occurred.The general data was collected,univariate analysis was conducted first,and then logistic regression analysis was conducted for items with statistical differences.Results Out of 86 parturient women with placenta previa after cesarean section,29 experienced postoperative bleeding,with a postoperative bleeding incidence rate of 33.72％(29/86).Univariate analysis showed that gestational weeks,parity,gravidity,placental attachment direction,number of uterine procedures,type of cesarean section incision,intraoperative anesthesia method,and history of prenatal bleeding were not associated with postoperative bleeding,without statistically significant differences(P＞0.05).The age,body mass index,type of placenta previa,history of cesarean section,presence of placental adhesions or implantations,history of miscarriage,and newborn birth weight were associated with postoperative bleeding,with statistically significant differences(P＜0.05).Logistic regression analysis showed that age ≥ 30 years old,body mass index ≥ 28 kg/m2,central type of placenta previa,history of cesarean section,placenta adhesion or implantation,history of miscarriage,and newborn weight ≥ 4 kg were independent risk factors for postoperative bleeding after cesarean section in parturient women with placenta previa(P＜0.05 and OR＞1).Conclusion The postoperative bleeding rate of parturient women with placenta previa after cesarean section is relatively high,which is related to factors such as age and body mass index.Clinical management measures should be developed based on these factors to minimize the risk of postoperative bleeding.
