Clinical Effect of Ascending Branch of Uterine Artery Ligation Combined With Postpartum Hemostatic Balloon in the Treatment of Central Placenta Previa
Objective To explore the clinical effect and impact of bilateral uterine artery ascending branch ligation combined with uterine cavity packing with postpartum hemostatic balloon during cesarean section on postpartum hemorrhage caused by central placenta previa.Methods A tota of 80 patients with postpartum hemorrhage caused by central placenta previa admitted to Mindong Hospital of Ningde City from January 2020 to December 2022 were selected as the research subjects.They were divided into an observation group(40 cases)and a control group(40 cases)according to treatment methods.The control group used traditional hemostatic techniques such as uterine compression suture and uterine cavity filling gauze during cesarean section.The observation group used a combined hemostatic technique of bilateral uterine artery ascending branch ligation and uterine cavity packing with Bakri balloons.The treatment effects were compared between the two groups.Results The observation group's haemostasis time,24 h haemorrhage,intraoperative haemorrhage,operation time and blood transfusion rate were better than those of the control group,the differences were statistically significant(P<0.05).After treatment,The hemoglobin level and erythrocyte pressure volume of the observation group were(98.82±3.24)g/L and(32.57±2.08)%,which were higher than those of the control group(95.65±2.77)g/L and(25.65±1.58)%,the differences were statistically significant(P<0.05).In terms of puerperal infection rate,hysterectomy rate,incidence of uterine artery embolism and ICU admission rate,there was no significant difference between the two groups(P>0.05).After treatment,the thrombin time(TT)level of the observation group was higher than that of the control group,and the levels of prothrombin time(PT),D-dimer(D-D)and fibrinogen(FIB)were lower than that of the control group,the difference was statistically significant(P<0.05).Conclusion The combined hemostatic technique of bilateral uterine artery ascending branch ligation combined with uterine cavity packing with postpartum hemostatic balloon has a significant clinical therapeutic effect on postpartum hemorrhage caused by central placenta previa,which can shorten surgical time,reduce bleeding volume,and does not increase the risk of postpartum infection and hysterectomy compared to traditional treatment plans.The research results of this article provide reference content for the later development of standards for the treatment of central placenta previa.
