Efficacy of Bakri Intrauterine Balloon in Managing Postpartum Hemorrhage: A Comparative Analysis of Vaginal and Cesarean Deliveries with Placenta Accreta Spectrum Disorders

Abstract

Background: The incidence of placenta accreta spectrum disorder (PAS) has been increasing in past decades, and women with PAS are a high-risk maternal population. This study aimed to explore the performance of Bakri intrauterine balloon tamponade (IUBT) in the treatment of postpartum hemorrhage (PPH), among those with and without PAS. Material/Methods: The outcomes of 198 women who underwent treatment for PPH using IUBT were retrospectively analyzed. The demographics and maternal outcomes were analyzed for vaginal and cesarean births, with PAS and without PAS. Results: Compared to women with vaginal births (n=130), women who underwent cesarean births (n=68) showed a higher proportion of age 335 years (c2=6.85, P=0.013), multiple births (c2=13.60, P<0.001), preeclampsia (c2=9.81, P=0.002), use of transabdominal IUBT (c2=84.12, P<0.001) and pre-IUBT interventions (c2=41.61, P<0.001), but had less infused volume of physiological saline (t=6.41, P<0.001). Women with PAS (n=105) showed a higher rate of pre-IUBT intervention (c2=4.96, P=0.029) and transabdominal IUBT placement (c2=9.37, P=0.002) than non-PAS women (n=93). The 36 women with PAS (n=36) showed a higher rate of preeclampsia (c2=4.80, P=0.029), pre-IUBT intervention (c2=5.90, P=0.015), and transabdominal IUBT placement (c2=14.94, P<0.001) and a shorter duration from delivery to Bakri insertion (c2=3.31, P=0.002), than non-PAS women (n=32). Conclusions: PAS was a major cause of PPH at 198 vaginal and cesarean births. An accurate and timely pre-IUBT intervention and Bakri IUBT placement was critical for controlling PPH in cesarean births, especially in women with PAS.
