能够预测哪些剖腹产可能导致子宫破裂

在一项研究中，在今天呈现孕产妇医学（SMFM）年会的社会，研究人员将揭示结果表明，通过使用超声图测量下子宫段（LUS）厚度，它们可以预测子宫疤痕缺陷先前剖腹产和预期哪些患者在随后的子宫破裂有风险的女性，如果他们有劳动力。

疾病控制网站的中心列出了国家重要统计系统的统计数据，表明剖宫产的数量急剧增加。"Preliminary data for 2005 indicate that 30.2% of all live births in the United States were cesarean deliveries, marking the highest U.S. total cesarean rate ever reported. Since 1996, the total cesarean rate has increased by 46%, driven by both an increase in the percentage of all women having a first cesarean and a decline in the percentage of women delivering vaginally after a previous cesarean."

重复剖腹产是一个明显的担忧。"There is a growing concern about the increase in cesarean births because there is a body of evidence showing that they are associated with higher rates of maternal and infant complications," said Emmanuel Bujold, M.D., with the Department of Obstetrics & Gynecology, Faculty of Medicine, Universite Laval, Quebec. "There are far fewer complications to the mother and infants as a result of a vaginal birth," he continued, "So it is important to determine when a patient with a history of prior cesarean section can have a vaginal birth safely."

这项研究看着236名有先前的剖宫产的女性。他们的LUS厚度在妊娠35至38周之间测量。报道了三种完全子宫破裂和六种子宫瘢痕裂开的病例。分析表明，劳动审判期间子宫破裂风险与全延迟厚度的风险有重大关联。完全LU厚度下的23mm厚度和单层肌肉封闭的组合与子宫破裂有显着相关（相对风险：21.8,95％CI：2.1-222，P，<0.0001）。

“研究结果将有助于我们以前给予生育的患者，我们之前给予患有剖腹产的患者，其中在劳动期间在劳动期间的患者患有高风险，”Bujold博士说。“这将有助于我们在下次建议妇女有阴道诞生。”

这些调查结果增加了1996年柳树上发表的罗桑伯格及同事研究的证据，并可能允许产科医生鼓励患者令人放心的LUS厚度有阴道分娩。
