Effect of Bakri balloon tamponade combined with different suture methods on preventing postpartum hemorrhage in women with pregnancy-induced hypertension undergoing cesarean delivery.

OBJECTIVE: To investigate the effect of Bakri balloon tamponade (BBT) combined with different suture methods on preventing postpartum hemorrhage in women with pregnancy-induced hypertension (PIH) undergoing cesarean delivery (CD).

METHODS: This randomized, double-blind, controlled trial was conducted at The First Affiliated Hospital of Xingtai Medical College from October 2020 to June 2023. Patients with PIH who had persistent bleeding after CD and were unresponsive to uterine contractions, sutures, or uterine disconnection procedures were eligible participants. Eligible participants were randomly assigned to control and study groups, with 50 patients in each group. The control group used BBT combined with B-lynch uterine compression sutures, while the study group used BBT combined with modified Hayman suture. Intraoperative and postoperative bleeding and changes in vital signs were compared between the 2 groups. Moreover, changes in inflammation levels, coagulation function, and sex hormone levels were compared between the 2 groups before and after surgery.

RESULTS: A total of 122 patients with persistent bleeding after CD were recruited, of whom 22 were excluded (16 cases of uterine contractions and/or local uterine myometrial sutures for hemostasis, 4 cases of preoperative uterine artery embolization, and 2 cases of uterine malformations). The intraoperative blood loss, postoperative blood loss at 2 hours, postoperative blood loss at 24 hours, and decrease in red blood cell and hemoglobin in the study group were significantly lower than those in the control group (P < .05). After surgery, the levels of inflammation, coagulation function, and sex hormone in both groups improved compared to before surgery, and the study group was significantly better than the control group (P < .05). In addition, the incidence of postoperative adverse events in the study group was significantly lower than that in the control group (P < .05).

CONCLUSIONS: The hemostatic effect of BBT combined with B-lynch uterine compression sutures is comparable to that of BBT combined with modified Hayman suture for postpartum hemorrhage in pregnant women with PIH undergoing CD, but the latter has less blood loss, attenuated inflammatory response, reduced impact on coagulation function and ovarian function, and a lower incidence of adverse events.
