Obstet Gynecol:妊娠期肝内胆汁淤积不会影响孕妇产后出血

2016-11-07 haofan MedSci原创

综上所述,在用熊去氧胆酸治疗的肝内胆汁淤积症的孕妇在妊娠38周内进行有计划的分娩(引产或剖宫产),她们的产后出血量并无差异。

最近,妇产科领域权威杂志Obstetrics and Gynecology上发表了一篇研究文章,旨在评估妊娠期肝内胆汁淤积对孕妇产后出血的影响。

在这项回顾性对照研究中,研究者在2004年至2014年期间共分析了15083例妊娠妇女,其中348例(2.3%)妊娠妇女出现肝内胆汁淤积症。为了调整各组基础特征存在的差异,对研究对象进行倾向性分析,并按照5:1的比例给患有肝内胆汁淤积症的妊娠妇女匹配正常妊娠妇女组成对照组。孕妇产后出血量通过估计失血量和Δ血红蛋白值(产前血红蛋白含量与产后血红蛋白之间的差值)来进行评估,研究者根据研究对象肝内胆汁淤积的严重程度(通过胆汁酸水平来衡量肝内胆汁淤积的严重程度)进行亚组分析,可分为三组:轻度肝内胆汁淤积症(胆汁酸水平小于40μmol/ L)、中度肝内胆汁淤积症(40–99μmol/ L),重度肝内胆汁淤积症(大于100μmol/ L),研究者进一步比较了各个亚组之间的失血量、Δ血红蛋白值和胎粪染色结果,另外,通过Spearman秩相关检验评估各个亚组胆汁酸水平与出血量之间的关系。

研究结果显示,两组间失血量(中位数为400[300–600]mL vs.400[300–600]mL,P=0.22),Δ血红蛋白(14[5–22] g/L vs.12[4–21]g/L,P=0.09),胎粪染色比例(14.5% vs.11.4%,P=0.12)均无明显差异。而且,相比于对照组,肝内胆汁淤积症孕妇在孕周26周后发生死胎的数量并不存在统计学差异(0.6% vs.1.8%,P=0.10)。相比于对照组,在中度和重度肝内胆汁淤积症孕妇中胎粪染色阳性明显增加(分别为23%、32.3% vs.11.4%,P< 0.01),而失血量、Δ血红蛋白与孕妇肝内胆汁淤积症的严重程度之间不存在相关性。

综上所述,在用熊去氧胆酸治疗的肝内胆汁淤积症的孕妇在妊娠38周内进行有计划的分娩(引产或剖宫产),她们的产后出血量并无差异。

AJOG:足月糖尿病孕妇选择引产术还是期待治疗?

研究者对孕期糖尿病孕妇进行了一项研究,探究引产孕周和剖宫产率间的关系。该研究纳入 863名孕期糖尿病孕妇,在孕37周后进行引产术或自发性镇痛。从医疗记录上获取参与者的人口统计学资料、宫颈情况和妊娠结局。比较同一孕周,进行引产术和期待治疗孕妇的剖宫产率。研究数据显示,校正初产、BMI、基线宫颈评分和孕妇年龄后,孕37周、孕38周和孕39周进行引产术与期待治疗孕妇相比,剖宫产风险相似,分别为aOR 1

孕期高脂高糖饮食将影响往后三代健康

有众多研究已经证明,孕妇进行高脂高糖饮食会提高死胎、后代先天性异常、肥胖和心脏疾病的风险。但一项新的研究表明,孕期高脂高糖饮食可能对后代的影响不止一代。孕期肥胖是很常见的,这将增大一些疾病的风险。根据疾病和预防控制中心(CDC)的数据,大约60%的孕妇孕期体重超标,不到30%的孕妇孕期接受了医疗机构关于体重控制的建议。此外,2008年的研究发现,10年间孕期肥胖比例增加了69%。然而在1993-1

AJOG:孕期接种百日咳疫苗的更佳时间

研究者对154名孕妇进行了一项前瞻性研究,探究孕期接种百日咳疫苗的最佳孕周时间窗口。参与者分为3组:未接种疫苗的对照组、早期疫苗接种组(孕28-32周)和晚期疫苗接种组(孕33-36周)。在疫苗接种前获取孕妇的静脉血样本,分娩时收集胎儿脐带血,检测血液中百日咳毒素 (PT)、百日咳杆菌粘附素(PRN)和百日咳丝状血凝素(FHA)的抗体水平。研究数据显示,三组孕妇血液中PRN和FHA抗体水平无差异,

Science:母亲妊娠期的微生物组塑造了后代的免疫系统

我们的肠道内生活着成千上万的细菌和微生物,它们组成了肠道微生物组。肠道微生物组在人类代谢食物、抵御感染和应答药物等过程中起到了重要的作用。许多人类疾病都与微生物组失衡有关。3月17日Science在线发表的一篇文章指出,母亲妊娠期的微生物组塑造了后代的免疫系统。此前有研究显示,新生儿的肠道菌群能影响自己的免疫系统。不过,我们还不清楚母亲肠道菌群对后代产生的影响。瑞士伯尔尼大学的研究人员构建了能自动

初步数据表明,孕期使用第二代抗精神病药物,不会增加后代主要畸形风险

在美国精神卫生大会上,研究者称,国家妊娠登记处非典型抗精神病药物的研究数据表明,孕期使用第二代抗精神病药不大可能会增加严重畸形风险。 来自哈佛医学院和马萨诸塞州总医院的Marlene P. Freeman博士称:研究的主要目的是探究孕期使用非典型抗精神病药物,后代出现主要畸形的发生率。这些畸形包括心脏缺损、唇裂或神经缺损。 研究纳入了487名年龄18至45岁的妇女,其中353名孕期在孕
