Analysis of prophylactic Bakri balloon tamponade failure in patients with placenta previa

摘要

ObjectiveRecently, Bakri balloon (BBT) was effective for women with placenta previa to reduce hemorrhage. However, about 10% of women needed to receive an invasive strategy. Thus, the identification of risk factors and the development of additional measurements for BBT failure was needed. The aim of our study is to investigate the cause and measurements of failing prophylactic BBT in women with placenta previa.Materials and methodsWomen with placenta previa who underwent cesarean section and had a prophylactic BBT inserted during the operation at our institution between January 2015 and December 2017 were enrolled. Patients requiring additional procedures after cesarean section for massive hemorrhage were defined as BBT failures. Additionally, the patterns and risk factors of BBT failure were retrospectively evaluated.ResultsSeventy women met the inclusion criteria. Of them, 9 (13%) were in the balloon failure group and 61 (87%), in the balloon success group. Between two groups, the median of postoperative blood loss was 1153?g vs. 70?g (p?
