Postpartum hemorrhage (PPH) is commonly defined as a blood loss within 24?h more than 500?ml at vaginal delivery or 1000?ml at cesarean delivery, it was mainly secondary to uterine atony, including atony of the lower uterine segment. Given all this, the bilateral-contralateral cervix clamp was firstly introduced and applied in postpartum hemorrhage, aiming to confirm its efficacy and safety against uterotonics.

Findings suggested that the bilateral-contralateral cervix clamp was simple, effective, safe, low-cost, which could be a complementary treatment for postpartum hemorrhage secondary to uterine atony at the third stage of labor or after delivery, especially appropriate for pregnant women with uterotonic contraindications and hospital in poor conditions.

Totally 47 pregnant women with postpartum hemorrhage secondary to lower uterine segment atony in vaginal delivery or after cesarean delivery were included from March 1, 2020 to May 31, 2020. According to the patient’s informed consent, 22 women accepted cervical clamp to treat and 25 only used uterotonics in the control group. Then hemostatic efficacy and safety of bilateral-contralateral cervix clamp were assessed by retrospective analysis.

It was found that mean blood loss in the clamp group was much less during vaginal delivery or after cesarean delivery, and incidence of uterotonic repeated usage or side effect appeared less than the control group, but there were no statistical differences on hospital stay, hemoglobin, blood transfusion, surgical procedures, also no clamp complications occurred.
