Abruptio placentae rarely produces severe maternal complications while the fetus is alive in utero. The advent of fetal death (grade III) indicates a severe form of abruptio placentae and a real risk that an overt coagulopathy might develop (grade IIIB). Overt coagulopathy associated with a live fetus is, however, uncommon. The advent of an overt coagulopathy should be viewed as ominous. Treatment of abruptio placentae with overt coagulopathy should be directed toward obtaining a rapid and atraumatic vaginal delivery. Once delivery has occurred, spontaneous reversal of the coagulopathy can be anticipated. In the opinion of one of the authors (G.S.), the advent of severe consumption coagulopathy and/or uterine inertia is an indication for intravenous therapy with aprotinin. It has been shown that such therapy will limit DIC, reverse fibrinolysis, reawaken uterine activity, and lead to rapid vaginal delivery within 6-8 hours. Aprotinin is not commercially available for clinical use in the United States. Prolongation of the abruption-delivery interval will worsen maternal prognosis. Accordingly, the advent of uterine inertia prior to complete cervical dilatation is an indication for immediate cesarean section in circumstances where aprotinin is not available. Following delivery, the physician should be on the lookout for postpartum hemorrhage, which may necessitate immediate transfusion, the administration of oxytocics, and/or uterine manipulation. Surgical intervention is rarely indicated in such cases. The patient should also be carefully observed over the ensuing days and weeks for the evolution and resolution of complications, such as renal failure, pulmonary insufficiency, and panhypopituitarism.
胎盘早剥在胎儿尚存活于子宫内时很少会引发严重的母体并发症。胎儿死亡(Ⅲ级)的出现表明胎盘早剥的严重形式以及可能发生明显凝血功能障碍(ⅢB级)的实际风险。然而,与存活胎儿相关的明显凝血功能障碍并不常见。出现明显凝血功能障碍应被视为不祥之兆。对于伴有明显凝血功能障碍的胎盘早剥的治疗应旨在实现快速且无创的阴道分娩。一旦分娩完成,可预期凝血功能障碍会自发逆转。据其中一位作者(G.S.)的观点,严重消耗性凝血功能障碍和/或子宫收缩乏力的出现是应用抑肽酶进行静脉治疗的指征。已表明这种治疗将限制弥散性血管内凝血(DIC)、逆转纤维蛋白溶解、恢复子宫活动,并在6 - 8小时内实现快速阴道分娩。在美国,抑肽酶没有用于临床的商业供应。胎盘早剥至分娩间隔的延长会使母体预后恶化。因此,在宫颈未完全扩张之前出现子宫收缩乏力是在无法获得抑肽酶的情况下立即行剖宫产的指征。分娩后,医生应留意产后出血,这可能需要立即输血、使用宫缩剂和/或进行子宫按摩。这种情况下很少需要手术干预。在随后的数天和数周内,还应仔细观察患者并发症的进展和消退情况,如肾衰竭、肺功能不全和全垂体功能减退。
