Disseminated intravascular coagulation due to placental abruption with intrauterine fetal death is not uncommon. It can result in increased maternal mortality rates and the need for hysterectomy or greater transfusion volumes if the delivery is not completed within six to eight hours. However, consensus is lacking regarding the delivery approach for cases in which delivery is prolonged.
A 37-year-old Japanese woman was transported to our tertiary center two and a half hours after the onset of labor because of a diagnosis of placental abruption with intrauterine fetal death at 40 weeks and three days' gestation. On arrival, although severe hypofibrinogenemia was observed, there was no external hemorrhage. Because her cervical canal dilation was good (Bishop score, 7), labor was induced using oxytocin. Anti-disseminated intravascular coagulation therapy was simultaneously started via transfusion. After her hypofibrinogenemia resolved, delivery progressed rapidly, and the fetus was delivered approximately 10 hours after the onset. To reduce postpartum hemorrhage, 6g of fibrinogen concentrate and tranexamic acid, an antifibrinolytic agent, were administered immediately before extraction of the dead fetus and placenta. Although the amount of intrapartum hemorrhage was 1824g, there was no abnormal bleeding after delivery, and our patient was discharged three days later.
In cases of placental abruption complicated with disseminated intravascular coagulation, intrapartum administration of coagulation factors can simultaneously promote effective labor and correct hypofibrinogenemia, enabling minimally invasive vaginal delivery.
胎盘早剥伴宫内胎儿死亡导致的弥散性血管内凝血并不少见。如果在六至八小时内未完成分娩,可能会导致孕产妇死亡率上升,以及需要进行子宫切除术或增加输血量。然而,对于分娩延迟的病例,在分娩方式上缺乏共识。
一名37岁的日本女性在分娩开始两小时半后被送往我们的三级中心,因为在妊娠40周零三天时被诊断为胎盘早剥伴宫内胎儿死亡。入院时,虽然观察到严重的低纤维蛋白原血症,但没有外部出血。由于她的宫颈管扩张良好(Bishop评分7分),使用催产素引产。同时通过输血开始抗弥散性血管内凝血治疗。在她的低纤维蛋白原血症得到缓解后,分娩进展迅速,胎儿在分娩开始后约10小时娩出。为减少产后出血,在取出死胎和胎盘前立即给予6克纤维蛋白原浓缩物和抗纤溶药物氨甲环酸。尽管产时出血量为1824克,但产后没有异常出血,我们的患者三天后出院。
在胎盘早剥合并弥散性血管内凝血的病例中,产时给予凝血因子可同时促进有效分娩并纠正低纤维蛋白原血症,实现微创阴道分娩。
