In this article, we try to discuss risk factors and diagnostic difficulties for uterine rupture.
Case series of 12 cases of uterine rupture observed in the Norfolk and Norwich University Hospital in the UK, with an average yearly birth rate of 6,000 deliveries, over a 6-year period.
In the present case series, there was no maternal mortality, and uterine rupture was a rare occurrence (12 in 36,000 births). Uterine rupture is associated with clinically significant uterine bleeding, fetal distress, expulsion or protrusion of the fetus, placenta or both into the abdominal cavity, and the need for prompt cesarean delivery and uterine repair or hysterectomy. The risk factors for rupture include previous cesarean sections, multiparity, malpresentation and obstructed labor, uterine anomalies, and use of prostaglandins for induction of labor. Previous cesarean section is, however, the most commonly associated risk factor. The most consistent early indicator of uterine rupture is the onset of a prolonged, persistent, and profound fetal bradycardia.
In this case series, we suggest that the signs and symptoms of uterine rupture are typically nonspecific, which makes diagnosis difficult. Delay in definitive therapy causes significant fetal morbidity. The inconsistent signs and the short time in prompting definitive treatment of uterine rupture make it a challenging event. For the best outcome, vaginal birth after previous cesarean section needs to be looked after in an appropriately staffed and equipped unit for an immediate cesarean delivery and advanced neonatal support.
在本文中,我们试图探讨子宫破裂的危险因素及诊断难点。
对英国诺福克和诺维奇大学医院观察到的12例子宫破裂病例进行系列研究,该医院6年期间平均年分娩率为6000例。
在本病例系列中,无孕产妇死亡,子宫破裂发生率较低(36000例分娩中有12例)。子宫破裂与临床上显著的子宫出血、胎儿窘迫、胎儿、胎盘或两者排入或突出至腹腔、需要紧急剖宫产及子宫修复或子宫切除术有关。破裂的危险因素包括既往剖宫产史、多产、胎位异常及产程梗阻、子宫畸形以及使用前列腺素引产。然而,既往剖宫产史是最常见的相关危险因素。子宫破裂最一致的早期指标是出现持续时间长、持久且严重的胎儿心动过缓。
在本病例系列中,我们认为子宫破裂的体征和症状通常不具有特异性,这使得诊断困难重重。确定性治疗的延迟会导致严重的胎儿发病。子宫破裂体征不一致且明确治疗的时间短,使其成为一个具有挑战性的情况。为了获得最佳结果,既往剖宫产术后经阴道分娩需要在人员配备适当且设备齐全的单位进行,以便能立即进行剖宫产及提供高级新生儿支持。
