Effect of routine rapid insertion of Bakri balloon tamponade on reducing hemorrhage from placenta previa during and after cesarean section.

PURPOSE: To evaluate the effectiveness of routine rapid insertion of a Bakri balloon during cesarean section for placenta previa based on a retrospective control study.

METHODS: Women with singleton pregnancies who underwent cesarean section for placenta previa at our institution between 2003 and 2016 were enrolled. Between 2015 and 2016, women who routinely underwent balloon tamponade during cesarean section were defined as the balloon group. Between 2003 and 2014, women who underwent no hemostatic procedures except balloon tamponade were defined as the non-balloon group. The clinical outcomes of the two groups were retrospectively analyzed.

RESULTS: Of the 266 women with placenta previa, 50 were in the balloon group and 216 were in the non-balloon group. The bleeding amounts were significantly smaller in the balloon group than in the non-balloon group: intraoperative bleeding (991 vs. 1250 g, p < 0.01), postoperative bleeding (62 vs. 150 g, p < 0.01), and total bleeding (1066 vs. 1451 g, p < 0.01). Furthermore, the mean surgical duration was shorter in the balloon group than the non-balloon group (30 vs. 50 min, p < 0.01). In the balloon group, five patients suffered from increasing hemorrhage due to prolapse of the balloon from the uterus after the operation, but the hemorrhage was controlled by balloon re-insertion without additional hemostatic procedures.

CONCLUSIONS: This study demonstrated that the routine rapid insertion of Bakri balloon tamponade during cesarean section significantly decreased intra- and postoperative hemorrhage and shortened the surgical duration in women with placenta previa.
