The Efficiency of Temporary Uterine Artery Ligation on Prevention of the Bleeding in Cesarean Section.

Objective: We aimed to evaluate the effect of temporary ligation of the uterine artery on postpartum bleeding during uncomplicated cesarean section.

Design: This was a prospective, randomized, and controlled study. We recruited a total of 200 patients, including 100 cases and 100 controls.

Methods: The bilateral uterine artery was temporarily clamped 2 cm below the uterine incision in the study group and compared with controls. Patient demographics, the amount of intraoperative bleeding, the duration of the operation, the closure time of the uterine incision, the need for additional uterotonics, the need for additional sutures, and the hemoglobin values before and after birth were assessed.

Results: The mean value of the amount of bleeding in the clamped and control groups was 267.3 ± 131.8 mL and 390.2 ± 116.4 mL, respectively. The amount of bleeding was significantly decreased for clamped group (p < 0.001). A significant reduction occurred in the results of pre- and postoperative values of hemoglobin and hematocrit difference, operation duration, and the closing time of the uterine incision in the experimental group which has temporary uterine artery clamping.

Limitations: The cases of recurrent cesareans were not included in this study.

Conclusion: Temporary uterine artery ligation can be used to reduce the amount of bleeding during uncomplicated cesarean delivery and prevent postpartum hemorrhage.
