The aim of this study was to evaluate the effectiveness of the Bakri balloon in treating postpartum hemorrhage refractory to medical treatment. This retrospective study included 24 women with postpartum hemorrhage treated with a Bakri balloon as a conservative therapeutic option. The Bakri balloon was successful in controlling hemorrhage in 87.5% of the women. It was effective in all women with vaginal delivery (five of five) and in all women with uterine atony who did not respond to medical uterotonic treatment (eight of eight). Its ease of use and high effectiveness make the Bakri balloon a useful approach for the conservative management of acute postpartum hemorrhage. This device reduces bleeding, shortens the hospital stay and avoids the need for more aggressive procedures.
