Effect of hemabate combined with low B-Lynch suture in the treatment of refractory placenta previa postpartum hemorrhage

Objective To investigate the efficacy of hemabate combined with low B-Lynch suture in the treatment of refractory placenta previa postpartum hemorrhage. Methods The clinical data from 96 patients with refractory placenta previa postpartum hemorrhage treated in Shanxi Maternal and Child Health Care Hospital from February 2017 to August 2019 were analyzed. And enrolled patients were divided into control group (48 cases) and observation group (48 cases) by their treatment methods. Patients in the control group were treated by oxytocin and interrupted figure 8 suture, and patients in the observation group were treated by hemabate and low B-Lynch suture. The curative effects, volume of bleeding and uterine volume were compared between the two groups. Results The total effective rate of treatment in the observation group was 97.92% (47/48), higher than the 83.33% (40/48) in the control group (P<0.05). The vaginal blood loss at 2 and 24 h after operation in the observation group were (60.39±12.64)ml and (31.26±6.41)ml, respectively, which were lower than the (124.43±24.72)ml and (65.68±9.27)ml in the control group (P<0.05). The uterine volumes in the observation group at 30 and 45 d after treatment were (167.53±18.29) cm3 and (103.14±15.29) cm3, respectively, which were smaller than the (208.42±23.46) cm3 and (146.19±18.37) cm3 in the control group (P<0.05). Conclusions Hemabate combined with low B-Lynch suture is effective in the treatment of refractory placenta previa postpartum hemorrhage, which can reduce postoperative bleeding and promote uterine recovery.
