RESUMO
OBJECTIVES: We developed a new Bakri balloon tamponade (BBT) placement technique after vaginal delivery, which aimed to be faster without balloon slippage. This study compared the new method with standard placement of BBT in women with postpartum hemorrhage (PPH) after vaginal delivery. MATERIAL AND METHODS: This study was undertaken of women who underwent vaginal delivery at the obstetrics and gynecology departments of the Hospital of Chengdu University of Traditional Chinese Medicine, Sichuan Provincial Hospital for Women and Children, and Si Chuan JINXIN Women and Children Hospital between January 2014 and December 2020. Women who underwent BBT for PPH were grouped according to placement method into the old-BBT group and the new-BBT group. RESULTS: Of 20487 childbirths by vaginal delivery, 512 (2.50%) had PPH, 77 women underwent BBT (old-BBT n = 28, new-BBT n = 49). Background characteristics were similar except prothrombin time (PT, p < 0.01) and activated partial thromboplastin time (APTT, p < 0.004) were lower in the new-BBT group than the old-BBT group. The operation time was shorter in the new-BBT group (p < 0.001) with less bleeding (p < 0.003) and saline injection (p < 0.001). A balloon slippage was less likely (p < 0.008) and postoperative bleeding (p < 0.01), transfusion rate (p < 0.03), transfusion volume (p < 0.002), and hospital stay was lower in the new-BBT group (p < 0.015). Multivariate analysis suggested PT (OR = 0.039, 95% CI: 0.002-0.730, p < 0.030), international normalized ratio (OR = 8.244, 95% CI: 3.807-17.850, p < 0.009), and BBT method (OR = 5.200, 95% CI: 1.745-15.493, p < 0.003), were associated with requiring a blood transfusion. CONCLUSIONS: This method of BBT placement reduced operation time, balloon slippage, bleeding, and hospital stay in women with PPH after vaginal delivery.
