宝妈到了预产期却还没生该怎么办?

发布日期:2024-06-28 10:46:28编辑:秩名


预产期到了还没生怎么办

很多孕妇都会遭遇到这个情况,预产期过了宝宝还是没动静。如果超过预产期怎么办?实际上预产期只是产妇预计生产的日期,并非精确的分娩日期,医生表示在预产期前后两周内分娩,都属正常。如怀孕24-36周间出生视为早产,在42周以后出生,则为逾期产。那么预产期到了还没生怎么办呢?一起来看看医生怎么说吧。
 
1、不要过于紧张,要注意胎动情况。一旦胎动每小时少于3次或在12小时内少于20次或胎动减弱,则需马上到医院作进一步检查,医生会根据情况决定分娩时机。
 
2、继续进行产检,并把孕早期的检查(如B超、验血、妊娠试验等)结果及胎动出现的时间、结果给医生,让医生再次核对孕周。
 
3、加强产前检查,缩短检查间隔时间,随时与医生取得联系,告知宫内胎动情况,同时B超随访羊水量。如果无异常,可在密切监护下继续妊娠。
 
如果预产期推迟到14天后,达到临床所谓过期妊娠时,由于部分孕妇的胎盘会出现老化、胎儿会出现缺氧窒息,所以对孩子的危害较大,应及时到医院采取措施。
 

到预产期不生的原因

医生表示预产期只是产妇预计生产的日期,并非精确的分娩日期,在预产期前后两周内分娩,都属正常。尽管如此,还是有不少产妇想了解到预产期不生的原因是什么。一起来听听医生的解析吧。
 
过期妊娠的病因尚不明确,但医生总结了几个可能引起过期妊娠的原因
 
1、雌激素水平低尽管临产的机制十分复杂,血中雌激素水平的高低与临产有密切关系,过期妊娠可能与血雌激素水平过低有关。但在大数量的过期妊娠中,并无雌激素水平低于普通正常妊娠的直接证明。
 
2、胎盘硫酸脂酶缺乏胎盘硫酸脂酶缺乏(placental sulfatase deficiency)是一种罕见的伴性隐性遗传病,本病由Ryan 1980年报道,患此症者虽然胎儿肾上腺产生了足量的16α-OH-DHEAS,但由于缺乏胎盘硫酸脂酶,无法将这种活性较弱的脱氢表雄酮转变成雌二醇及雌三醇,以致发生过期妊娠。
 
3、头盆不称过期妊娠中部分胎儿较大,胎头迟迟未入盆,宫颈未受到应有的刺激,使产程的开始推迟。这是较多见的原因。
 
4、遗传有少数妇女的妊娠期较长,数胎均出现过期妊娠,有时尚见于一个家族,说明这种倾向可能与遗传有关。
 

过了预产期如何催生

妊娠达到或超过42周(即超过预产期2周)称为过期妊娠。妊娠过期会使胎盘老化,从而使绒毛间隙血流量明显下降,形成梗塞,进一步使血流量减少,供应给胎儿的氧气和营养物质减少,使胎儿不再继续生长。这种情况下需要进行催生,以保证胎儿的健康而安全。那么有什么催生的方法呢?
 
1、运动催生法
 
准妈妈加强运动能促使胎儿入盆,同时还能锻炼盆底肌肉,增加产力。不过,出门运动的时候最好能找个“保镖”,以防突然发生“紧急情况”。医生表示散步能帮助胎儿下降入盆,松弛骨盆韧带,有利于顺利分娩;产前体操在国外非常流行,体操不但可以促使胎头入盆,而且可以增加骨盆底肌肉的韧性和弹性;爬楼梯可以锻炼大腿和臀部的肌肉群,并帮助胎儿入盆,使第一产程尽快到来。
 
2、饮食催生法
 
医生表示,临产时食用冬苋莱粥和空心菜粥,能使孕妈妈更加顺利地分娩,不但加快了产程,也减少了妈妈的痛苦。
 
3、药物催生
 
如果其他方法不能使孕妈妈提早感到阵痛,那么只好用药物催产了。在使用催产素催产前,孕妈妈必须要接受一系列的检查和监测,来评估胎儿状况和胎盘功能。如B超检查能得知胎盘成熟度、羊水量、胎儿大小、脐带血流速度。医生可根据检查结果决定是否需要给准妈妈使用催产素;有经验的产科医师,可通过准妈妈宫颈指诊来评估子宫颈成熟度(子宫颈的柔软度和子宫外口的扩张度),进而考虑是否早一点接受催生处理。
 

预产期不准该注意什么

在预产期提前让宝宝出生不利于其健康,而过期妊娠,不但不利于宝宝的生长发育,相反得给包包健康带来潜在的威胁。如果预产期不准,产妇应该注意些什么呢?准妈妈们一起来看看吧,多加留心,让宝宝顺利出生健康成长。
 
1、尽早住院,抛弃“妈妈腹中呆一天,胜过外面长三天”的错误观念。 
 
2、确定预产期是否真正过期。平时月经周期不很规则的孕妇更应顾及这个问题。这些孕妇可能由于排卵延迟,而使预产期相应推迟。所以按原先最后一次月经日期而推算的预产期并不是真正的预产期,若在那里随意引产可能会造成早产,影响宝宝的健康成长。此时,准妈妈应准确地向医生提供这次妊娠出现早孕反应、胎动的时间以及怀孕早期B超的检查结果。 
 
3、积极配合医生检查和治疗。一旦确诊妊娠已过期或即将过期,医生会进行一毓检查,了解胎盘功能和胎儿生长情况。若胎盘功能正常,短时间内,胎儿还在继续生长,胎儿面临的危险较小,医生会在严密监视下采取引产的方法;若胎盘功能不良,胎儿停止生长,则胎儿面临死亡的威胁,医生会在短期内进行手术终止妊娠,以确保母子平安。 
 
4、切忌自做主张,干扰医生决定。这样不仅可能延误治疗时机,而且还会影响医生的情绪,对已对宝宝都是极为不利的。
 

孕妇分娩前的症状有哪些

医生表示了解孕妇分娩前的症状表现,可以帮助准妈妈们做好分娩前准备。那么孕妇分娩前的症状具体表现为什么呢?一起来听听医生的解析吧。
 
有规律的痉挛或后背痛:这是子宫交替收缩和松弛所以引起的。随着分娩的时间的推进,这种收缩感会加剧。由于子宫颈的胀大和胎儿自生殖道中产出,疼痛是必然的,不过对胎儿有很大的好处。这种现象只是发生在分娩开始时。胎儿头沉入产妇骨盆,产妇感觉好象胎儿要掉下来一样。这种情况多发生在分娩前的一周或数小时。
 
阴道流出物增加:这是由于孕期粘稠的分泌物累积在子宫颈口,由于粘稠的原因,平时就象塞子一样,将分泌物堵住。当接近生产时,子宫颈胀大,这个塞子就不起作用了,因为分泌物会流出来。这种现象多在分娩前数日或在即将分娩前发生。
 
在分娩前的几天甚至几周里,假宫缩可能会做一些前期准备的工作,让你的子宫颈变软、变薄,也许还会使你的子宫颈稍微张开。如果你生过孩子,你的子宫颈在产程开始前,便有可能会打开1~2厘米。但要知道:如果这是你的第一胎,即使你怀孕40周,你的子宫颈张开了1厘米,也不能保证你马上就要生了。
 
随着分娩的临近,如果你的子宫颈开始张开,你可能会排出宫颈粘液栓——少量稠厚的粘液,在过去的9个月里,它起到密封子宫颈管的作用。这块粘栓可能会一次性成块地被排出,也可能会以增多的阴道分泌物的形式在几天内排出。
