孕育拦路虎:先兆流产怎么办?
  2024/04/23| 阅读次数:181
怀孕对一个家庭而言是惊喜的、期待的,准妈妈会每天憧憬宝宝发育,直到顺利生下宝宝。


然而,事情不会总是那么尽如人意,怀孕的一路上会出现几只“拦路虎”,先兆流产就是其中之一。


什么是先兆流产?


先兆流产是指在妊娠早期出现的阴道少量出血,时下时止,伴有轻微下腹痛和腰酸的一种疾病,妊娠12周内为早期先兆流产,12-28周的则称晚期先兆流产。

因此,先兆流产有3个明显症状:阴道出血、下腹痛和腰酸。怀孕过程中,一旦出现了这3种症状,千万别迟疑立刻就医。

值得注意的是,先兆流产的发生率并不低,报道的发生率为12%~24%[1],而实际的发生率可能更高,因为有些流产会发生在月经期前后,似月经期延长或月经间隔延长,比如生化妊娠。

更尴尬的是,如果反复流产2次及以上,就会变成习惯性流产,发生率为1-2%。但是一旦经历3次流产,下次流产的几率就陡增为30%~45%[2]。

那么为什么会流产呢?其实原因是多方面的,主要是两种:染色体异常和母体因素。

在早期自然流产中有50%~60%的妊娠物有染色体异常。夫妇中如有一人染色体异常,则可传至子代,可导致流产或反复流产。

母体因素主要有:内分泌异常、子宫缺陷、全身性疾病以及免疫功能异常等,这些都会影响胚胎在子宫内茁壮成长。其中内分泌异常最为常见的就是黄体功能不足。


如何治疗先兆流产?


先兆流产的治疗目的是尽可能的使妊娠继续,常见的治疗方法主要是以下3种:

01
适度卧床
卧床休息并不是说24小时都躺在床上不动,可以起床完成简单的日常活动,如吃饭、喝水、上厕所、散步,活动的选择和持续时间以不使自己感觉到疲惫及加重先兆流产的症状为宜。

如果整天都卧床休息的话,会使孕妇全身血液循环变得更缓慢,容易出现下肢、盆腔的深静脉血栓,影响最后的妊娠结局。
02
药物治疗
药物治疗常见的就是各类保胎药,比如孕激素等。孕激素可以维持子宫内膜生长,利于受精卵着床、成长,可以抑制宫缩,降低子宫肌肉对各种刺激的敏感性。

烯丙雌醇作为孕激素的一种,发挥多重机制治疗先兆流产:促进受精卵着床,改善胎盘功能, 拮抗催产素、前列腺素对子宫的刺激。

自1972年在匈牙利上市以来,共被29个国家批准使用,有50余年的临床使用经验,被证实是安全可靠的,无不良反应及重大安全事故报道。
03
保持放松愉悦的心情
先兆流产保胎期间孕妇一定要保持心情放松愉悦,不要给自己太大的压力,因为有一部分自然流产是因为孕妇中枢神经兴奋所致。

因此,一定要注意调节自己的情绪,消除紧张、焦躁、恐惧心理,切记不可情绪波动过大,比如大喜、大悲、大怒、大忧,负面的情绪不利于胎儿的生长发育。
