“…Recently, a nationwide survey of severe PPH was conducted in Japan, using national health insurance claims. The survey has reported that the rate of severe PPH increased annually 5 . Multiparity, multiple pregnancies, macrosomia, polyhydramnios, hypertensive disorders of pregnancy (HDP), uterine leiomyoma, assisted reproduction technology, maternal hematologic disease, and abnormal placentation, such as placenta previa and placental abruption, are well recognized risk factors for PPH 4,6‐8 .…”

Objective To examine the association between the risk of postpartum hemorrhage (PPH) and poor uterine contractility, which is suggested by the characteristics of labor. Methods This case‐control study used cases recorded in the Japan Perinatal Registry database during the period 2013–2016. After exclusion of women with specified known risk factors for PPH, we enrolled 174 082 primiparas who had a full‐term live singleton vaginal birth. Participants were classified into four classes according to the diagnosis of abnormal labor patterns and use of uterotonics. χ2 tests were used to compare PPH cases with controls, and odds ratios (OR) were calculated by univariate and multivariate analyses. Results Among the enrolled women, 10 508 (6.0%) had PPH. Abnormal labor patterns were significantly associated with an increased risk of PPH. Compared with women without any abnormal labor patterns who had not used uterotonics, women with abnormal labor patterns were at a significantly increased risk for PPH regardless of whether they had used uterotonics (adjusted OR 1.23, 95% confidence interval [CI] 1.10–1.37) or not (adjusted OR 1.30, 95% CI 1.23–1.37). Conclusion Our study suggests that among low‐risk women with PPH, poor uterine contractility in labor could be a significant predisposing risk factor for PPH.

“…An atonic uterus is the most common cause of severe PPH. 1 The reference standard for treating atonic PPH is adequate uterotonics and uterine fundal massage, optionally using bimanual compression of the uterus, intrauterine balloon tamponade, and correction of coagulopathy. Patients who resist these treatments require arterial embolization or surgical interventions such as uterine compression sutures (UCS) or hysterectomy.…”

Introduction Postpartum hemorrhage is the most common cause of maternal death worldwide. Although intrauterine balloon tamponade has been widely used as an effective procedure to control atonic postpartum hemorrhage, intrauterine balloon tamponade fails to control postpartum hemorrhage in approximately one‐fifth of cases. The aim of this study was to evaluate the efficacy of novel intrauterine balloon tamponade systems for postpartum hemorrhage. Material and methods We have developed two novel intrauterine balloon tamponade systems to maintain proper balloon placement. One was a shaft cover with its fixture system and the other was “the Kyoto balloon system” designed to provide direct pressure onto the upper uterine cavity. The efficacy of the intrauterine balloon tamponade systems was evaluated using a silicone three‐dimensionally printed postpartum uterine cavity model. Results Measurements of balloon displacement during inflation showed that the shaft cover significantly prevented the Bakri balloon from being displaced. The residual fluid volume in the upper uterine cavity was significantly less with the Kyoto balloon system than with the Bakri balloon system, indicating the effectiveness of the Kyoto balloon for upper uterine cavity tamponade. Conclusions These innovative intrauterine balloon tamponade systems were effective for prevention of balloon displacement and for balloon tamponade of the upper uterine cavity in a 3D‐printed postpartum‐specific uterine cavity model.

Nationwide survey of severe postpartum hemorrhage in Japan: an exploratory study using the national database of health insurance claims

Abstract: This nationwide survey indicates that the annual incidence of severe PPH is increasing. Furthermore, FFP has become more prevalent in small-scale obstetric facilities.
