Objective: To determine the efcacy of the Bakri balloon in the prevention of hysterectomy due to postpartum hemorrhage versus conventional management with uterotonics. Material and method: Retrospective observational cross-sectional study in women with postpartum uterine hemorrhage treated at La Samaritana University Hospital in the city of Bogotá, Colombia, between 2013 and 2019. Clinical records were reviewed and divided into two groups: Bakri balloon and uterotonics (no Bakri balloon). Results: Overall, 81 patients with postpartum uterine hemorrhage were included, 27 patients (33.3%) were considered exposed (Bakri balloon) and 54 patients (66.6%) unexposed (no Bakri). The success rate dened as stopping the bleeding and not requiring hysterectomy with the Bakri balloon was 96.3%, versus the no Bakri group, 68.52% (p = 0.04). In addition, the Bakri balloon reduced the risk of hysterectomy by 99% (OR = 0.01; 95% CI 0.008-0.38; p = 0.01), when adjusting for age and gestations. Conclusions: The use of the balloon demonstrated a high rate of effectiveness, decreased the risk of hysterectomy and was shown to be an easy and safe method for the management of postpartum hemorrhage due to uterine atony. aThe Bakri balloon is available to health institutions in countries with limited resources such as ours, where it constitutes an essential tool to deal with a pathology associated with a high risk of mortality as is the case with postpartum hemorrhage.
