Clinical outcome analysis of modified B-Lynch sutures in the fundus uteri and part of the corpus uteri for the prevention of intraoperative haemorrhage during caesarean delivery in women with twin pregnancy: a retrospective study.

Objective: To explore the efficacy of modified B-Lynch sutures in the fundus uteri and part of the corpus uteri for the prevention of intraoperative haemorrhage during caesarean delivery in women with twin pregnancy.

Methods: This retrospective analysis covers the clinical data of 40 women with postpartum haemorrhage caused by uterine inertia during caesarean section in women with twin pregnancy in our hospital from January 2018 to May 2022. These women were divided into the group with modified B-Lynch sutures at the fundus and part of the corpus uteri (Group A, 20 patients) and the group with classic B-Lynch sutures (Group B, 20 patients) according to the treatment received. The treatment effect and safety of the two uterine compression sutures were compared.

Results: In this study, no statistically significant differences were found in the outcomes of haemostasis or intraoperative and 24-h postoperative blood loss between the two uterine compression suture groups (P > 0.05). Compared to Group B, Group A showed a significantly reduced operative time, postoperative hospital stay, puerperal morbidity rate, pain score and duration of lochia.

Conclusion: Modified B-Lynch sutures at the fundus and part of the corpus uteri can achieve a haemostatic effect similar to that of the classic B-Lynch suture, while it allows for a shortened operative time and reduced postoperative complications. Modified B-Lynch sutures can serve as a safe, rapid and effective haemostatic method for the prevention and treatment of postpartum haemorrhage during caesarean section in women with twin pregnancy, showing certain validity for promotion in clinics.
