Comparison of hemostatic effect of bilateral uterine artery upstream ligation and gauze intrauterine caused by preoperative placenta cesarean section hemorrhage

Abstract

Objective To compare hemostatic effect of bilateral uterine artery superior branch ligation and gauze intrauterine filling two methods for the placenta previa cesarean section bleeding. Methods 100 patients with bleeding in cesarean section were randomly divided into observation group (50 cases) and control group (50 cases). The patients in the observation group were treated with bilateral uterine artery ascending branch, and the control group was treated with gauze.The number of blood transfusion, the time of operation, the amount of bleeding, the time of hemostasis, the number of hysterectomy and the occurrence of complications were compared between the two groups. Results The success rate of hemostasis in the observation group (98.0%) was higher than that in the control group (86.0%), the difference was statistically significant (χ2=4.891, P<0.05). The bleeding volume and hemostasis time were (577.8±55.9) mL, (19.2±10.2)min, the differences between the two groups were statistically significant (t=2.50, 3.25, all P<0.05). The operation time between the two groups had no significant difference (P<0.05). The transfusion rate and incidence rate of complications in the observation group were 8.0% and 6.0%, which were significantly lower than those in the control group (22.0%, 20.0%), and the differences were statistically significant (χ2=3.843, 4.332, all P<0.05). Conclusion The use of bilateral uterine artery esophageal branching in the placenta previa is effective in controlling bleeding, it has rapid bleeding and low incidence of complications, and is worthy of clinical application.
