Clinical outcomes of prophylactic compression sutures for treatment of uterine atony during the cesarean delivery of twins

BACKGROUND: Twin pregnancy has a high risk for developing uterine atony (UA). This study aimed to evaluate efficacy and clinical outcomes of prophylactic compression sutures to treat UA during twin cesarean section (CS). METHODS: All patient records of twin deliveries by CS after gestational age of 24 weeks in a large maternity hospital in South Korea between January 2013 and June 2018 were reviewed. Patients with monochorionic monoamniotic twins were excluded from data analysis. In total, 953 women were eligible for data analysis. RESULTS: Of the 953 patients, compression sutures were applied to 147 cases with postpartum bleeding that were refractory to uterine massage and uterotonics. Out of the 147, two patients (1.4%) proceeded to additional uterine artery ligation to achieve hemostasis, yielding a success rate of 98.6%. The rate of transfusion after the first 24 h of delivery in the suture group was not significantly different from that in the non-suture group, suggesting that both groups achieved hemostasis at an equal rate after the first 24 h of delivery. The difference in the operation time between the two groups was only 8.5 min. The rate of subsequent pregnancy among the patients who received compression sutures was 44.4%. CONCLUSIONS: Overall, our findings suggest that with early and fast implementation of compression sutures, UA can be treated in the setting of twin cesarean delivery without significantly increasing maternal morbidity.
